Genesis Nanotech – “Great Things from Small Things”

Scientists have shown for the first time that briefly tuning into a person’s individual brainwave cycle before they perform a learning task dramatically boosts the speed at which cognitive skills improve.

Calibrating rates of information delivery to match the natural tempo of our brains increases our capacity to absorb and adapt to new information, according to the team behind the study.

University of Cambridge researchers say that these techniques could help us retain “neuroplasticity” much later in life and advance lifelong learning.

Building A Better Battery for America … In America – Is Lithium Iron Phosphate (LIP) Making a ‘Comeback’ in North America?

Credit: David Giral Photography | Nano One Materials’s Montreal factory, originally commissioned in 2012, is the only facility in North America that can produce meaningful quantities of lithium iron phosphate.


Electric car companies in North America plan to cut costs by adopting batteries made with the raw material lithium iron phosphate (LFP), which is less expensive than alternatives made with nickel and cobalt.

Many carmakers are also trying to reduce their dependence on components from China, but nearly all LFP batteries and the raw materials used to make them currently come from China. A number of companies are now planning the first large-scale LFP factories in North America. Some are partnering with established companies, and others hope to introduce new technologies that will leapfrog Chinese competitors.


On a bookshelf in his home near Montreal, Denis Geoffroy keeps a small vial of lithium iron phosphate, a slate gray powder known as LFP. He made the material nearly 20 years ago while helping the Canadian firm Phostech Lithium scale up production for use in cathodes, which is the positive end of a battery and represents the bulk of its cost.

At the time, Phostech was making only about 1 metric ton (t) of LFP per year. Geoffroy mixed the precursors at a facility in Quebec and cooked the mixture in a kiln in Ontario, more than 700 km away. “Then I would put it in my car and drive home,” he says. “I would go to FedEx to ship it to customers.”

Eventually, Phostech graduated to bigger LFP factories, culminating in a 2,400 t per year plant near Montreal in 2012. Despite the progress, LFP never caught on as a chemistry for electric vehicle batteries in North America. Carmakers in the region opted instead for cathodes made with nickel and cobalt, which offer higher energy density and more range. In 2021, Johnson Matthey, which acquired the Montreal facility in 2015, put the plant up for sale.

Nickel and cobalt prices have increased substantially in the past few years, however, and nonprofit watchdogs say mining for the metals is connected to environmental problems and child labor. Nickel-based batteries are also more likely to catch fire and can’t be recharged as many times as LFP batteries.

After initially snubbing the chemistry, several big carmakers are now turning to LFP as a way to cut lithium-ion battery costs.

Ford, Rivian, and Volkswagen have all unveiled plans to use LFP in North American cars, and General Motors is interested as well. A turning point came in October 2021, when Tesla, which accounted for two-thirds of US electric car registrations last year, revealed that it would switch to LFP batteries for all its standard-range vehicles globally.

Western carmakers also want to reduce their dependence on materials from China. At the moment, China is the source of nearly all LFP batteries and the cathode powders required to make them, but several companies are trying to change that.

In October, the Israeli chemical maker ICL Group announced plans to build an LFP cathode powder factory in Missouri. The Norwegian start-up Freyr Battery and Utah-based American Battery Factory plan to make LFP cathode material in the US for their battery factories in Georgia and Arizona, respectively. Meanwhile, China’s Gotion High-Tech hopes to establish LFP cathode material production in Michigan. Other Chinese manufacturers are also weighing how to leverage their expertise in North America.

In November, the start-up Nano One Materials finalized the purchase of the old Phostech LFP plant in Montreal, promising to introduce a manufacturing process that will require less energy and produce less waste than existing methods. Geoffroy, now Nano One’s chief commercialization officer, has returned to the factory to pilot the new process and scale it up.

“I designed it, built it, managed it, left it . . . and now we’re rebuilding,” Geoffroy says. “For me, it’s a chance to do what I planned on doing with a process that I believe in.”


The energy powering an electric car is released when electrons from a lithium-​ion battery’s negatively charged electrode, called the anode, flow through the motor into the battery’s positively charged cathode. To balance the electrons leaving the anode, the cathode must simultaneously accept positively charged lithium ions from an electrolyte solution.

Batteries with anodes that produce lots of electrons, and cathodes that are eager to suck them up, have a high voltage, which allows them to store more energy in a given volume. Energy density can be increased by using cathode and anode materials that can store more lithium ions.

Because nickel and cobalt cathode materials can store lots of lithium and generate a high voltage, they were used in some of the first commercial lithium-ion batteries. But even in the early days of battery development, researchers saw room for improvement.

“We wanted to reduce the cost, so we pursued cathodes based on iron, which is abundant and a cheaper metal,” says Arumugam Manthiram, a University of Texas at Austin researcher who worked with the battery trailblazer John Goodenough for decades and laid the groundwork for the class of cathodes that includes LFP.

In the mid-1990s, other researchers from Goodenough’s lab proposed using LFP, arguing that it was cheap and nontoxic. But the material wasn’t very conductive, which limited its utility. A few years later, building on the Goodenough lab’s initial discovery, scientists at Hydro-Québec and the University of Montreal solved the conductivity problem by coating LFP with carbon. Though LFP batteries still couldn’t match the energy density of nickel-based batteries, their lower cost made them appealing.

In 2003, Hydro-Québec and the University of Montreal gave Phostech the first license to manufacture LFP commercially. But investors backing North American projects were cautious, and progress was slow. “We had half a million dollars to survive for 3 years,” Geoffroy recalls. “I was paying myself by selling samples.”

Things accelerated for Phostech in 2005, when the German chemical company Süd-Chemie, which was developing a different LFP manufacturing process, bought a majority stake in Phostech. Süd-Chemie financed pilot facilities and the 2,400 t plant near Montreal, but the German firm’s hydrothermal process turned out to be more expensive than Phostech’s solid-state method. Clariant acquired Süd-Chemie in 2012 and promptly sold the LFP business to Johnson Matthey.

Geoffroy left Johnson Matthey in 2019 without seeing the plant become big enough to meaningfully supply the auto industry. “When we bought the land in 2007 there was expansion planned,” he recalls. “We never expanded.”

Other North American companies also sought to capitalize on the discovery of LFP, with limited success. In 2009, the Massachusetts Institute of Technology spinout A123 Systems raised $350 million in an initial public offering, aiming to manufacture a modified version of LFP in Michigan. But not enough carmakers were interested, and A123 went bankrupt in 2012. Most of the firm’s assets were acquired by China’s Wanxiang Group.


LFP was invented and developed in North America, but Chinese companies were the first to place a big bet on the technology, according to Karim Zaghib, a battery scientist at Concordia University who worked for Hydro-Québec in the 1990s.

After successfully installing LFP batteries on buses ahead of the 2008 Beijing Olympics, China, impressed by the chemistry’s improved fire safety compared with nickel-based batteries, made LFP production a national project, Zaghib says. “The Chinese government and Chinese companies invested a lot in LFP.”

And the material has been a hit. In 2021, more than 40% of electric vehicles sold in China had LFP in their batteries, according to the market research firm Adamas Intelligence. “In China, small electric vehicles . . . with a range of 120 km are very popular,” says Alla Kolesnikova, head of data analytics at Adamas. “The majority of them are powered by LFP.”

Most factories in China produce LFP using a solid-state process that starts with the reaction of iron sulfate and phosphoric acid to produce iron phosphate. Usually the iron phosphate is then mixed with lithium carbonate and a source of carbon that forms the conductive coating.

That mixture is then sent in a ceramic crucible into a kiln, where it reaches temperatures of 700–800 °C. The heat sinters the material, changing it from an amorphous mixture into the olivine structure that allows it to function as a cathode.

Between 2010 and 2016, China’s capacity to make LFP cells, or individual battery units, increased 100-fold, according to Cormac O’Laoire, managing director of the Hong Kong–based battery consulting firm Electrios Energy. By 2021, he says, Chinese companies were producing over 90% of the world’s LFP powder.

In a little over 10 years, one Chinese company, Shenzhen Dynanonic, increased its annual LFP capacity from 500 t to 265,000 t. Unlike other firms in China, Dynanonic uses a solution-based production method that resembles the hydrothermal process Süd-Chemie used in Montreal.

Suki Zhang, Dynanonic’s account manager for overseas markets, says most of its growth has come in the past 2 years, a period when Chinese battery manufacturers, such as Contemporary Amperex Technology Co. Limited (CATL), were investing heavily in LFP. “We have so many batteries here,” she says. “The demand is a big reason why we built LFP in China.”

Chinese factories are able to make LFP cheaply, in part because the consortium of organizations that owned the relevant patents—including France’s National Center for Scientific Research, Hydro-Québec, Johnson Matthey, and the University of Montreal—agreed not to charge Chinese companies licensing fees if they sold only in China, according to an International Energy Agency report. In contrast, the Taiwan-based LFP maker Aleees says it paid about 10% of its sales in licensing fees until recently.

The intellectual property was held more closely in other parts of the world. “That may have limited some of the development of LFP in the US and Europe,” says Anantha Desikan, ICL’s chief technology officer.

James Frith, a principal at the venture capital firm Volta Energy Technologies, points out that China has other advantages. Iron sulfate is cheap there because it’s available as a by-product of titanium dioxide production, which isn’t the case outside China, where most makers of the pigment use a different process. Frith says less-stringent environmental regulations in China can also reduce costs.

Over the past few years, the core patents behind LFP manufacturing have expired, removing a barrier for non-Chinese companies interested in producing LFP. O’Laoire says the expirations also make it easier for Chinese companies to serve markets where the patents were previously enforced.

Zhang says Dynanonic is now considering an overseas expansion, though the company hasn’t yet disclosed a specific location. Any such project would depend on the strength of battery manufacturing in other countries as well as on the rules for implementing clean energy policies like the Inflation Reduction Act, the landmark US legislation that is projected to inject $142 billion into companies making batteries or battery components in the US.

Other Chinese battery companies have already started expanding overseas. Gotion High-Tech, which has been producing LFP batteries and cathode materials in China since 2007, plans to build 100 GW h of battery cell capacity outside China over the next 3 years. In June 2022, Gotion, whose biggest shareholder is Volkswagen, announced plans for its first LFP battery factory in Europe.

A few months later, an economic development agency in Michigan awarded Gotion’s US subsidiary grants and tax incentives to help construct a $2.4 billion plant in Big Rapids, Michigan. If built as planned, the factory will produce 150,000 t of LFP cathode material per year.

“The companies that understand how to make the product are looking to expand in other regions,” Chuck Thelen, a Gotion vice president, said at a December informational meetinghosted by Big Rapids officials.


Some Western firms setting up LFP cathode production in North America plan to work with partners and use established processes. Others hope to outcompete Chinese firms with new technologies.

ICL, which produces industrial phosphates and other chemicals, has been on the periphery of the LFP industry for years. It analyzed cathode materials from A123 before the company went bankrupt and began providing phosphate raw materials to LFP firms in China in 2021. In early 2022, ICL decided LFP had gained enough momentum outside China to warrant venturing into battery materials on its own.

In October 2022, the company received a $200 million US Department of Energy grant to build a 30,000 t per year LFP cathode material factory at its Saint Louis site, which has been producing phosphorus chemicals for more than a century. “We’ve been making phosphate salts since 1876,” says Tom Murray, ICL’s director of R&D. “Lithium iron phosphate is not very different.”

One potential difference from Chinese factories could be ICL’s starting materials. The company is evaluating using iron oxide rather than iron sulfate, which can be difficult to procure outside China. Iron oxide is more expensive, but Murray says the process produces higher-quality LFP.

At the Missouri plant, ICL will use technology from Aleees, which has been manufacturing LFP materials for nearly 2 decades. Murray says the partnership combines Aleees’s deep experience in high-quality LFP production with ICL’s expertise in large-scale chemical manufacturing. “Without them, it would be a struggle for us to jump into this and make any headway,” he says.

Eric Chang, president of Aleees’s licensing business, says the company is eager to partner with companies like ICL because its ability to expand in Taiwan is limited by the price of land. Over the last 6 months, the company has also agreed to provide its cathode manufacturing technology to Norway’s Freyr and Australia’s Avenira.

In November, Freyr announced that it would build a $1.7 billion, 34 GW h battery factory in Georgia, and Chang says Aleees plans to help Freyr make LFP cathode materials to supply that plant.

American Battery Factory, a Utah-based company that hopes to serve the stationary energy storage market, is also partnering with an established cathode manufacturer, as yet unnamed, to set up production of LFP cathode materials in the US. The powder it makes would supply the company’s proposed cell factory in Arizona and could also be sold to other companies.

Frith says China’s cheap labor, energy, and raw materials will make it difficult for Western firms to match the country’s low cost of production, but provisions in the Inflation Reduction Act may give companies in the US enough of a boost. “Without that, I think you’re unlikely to find LFP production moving outside of China,” he says. “The economics just aren’t really there to promote it.”

While Aleees’s product costs more than LFP made in China, Chang argues that the firm is better than Chinese competitors at customizing its output for specific customers. “They lack the flexibility to fine-tune the parameters or the characteristics or properties of LFP,” he says. “They make it more like a commodity rather than a specialty chemical.”


Some Western companies are hoping to beat Chinese competitors with new technologies that can produce high-quality LFP with a lower environmental footprint.

Nano One CEO Dan Blondal says imitating China’s solid-state process in North America could be challenging because it creates lots of sulfate waste. “China largely sweeps it under the rug,” he says. “As you try to bring that out of China to everywhere else, it’s a big impediment. It’s gonna be hellish to permit that.”

Instead, Nano One plans to use pure iron metal as an LFP precursor, eliminating the sulfate waste stream. The company also claims that this method makes the cooking step more efficient, saving energy.

Nano One is just starting to set up shop at its recently purchased Montreal factory. Temporary banners with the company’s name hang from the ceiling, but the plant’s handful of employees still wear Johnson Matthey uniforms, and bags of LFP left over from the transition bear the Johnson Matthey logo.

On the factory floor, the 100 L glass reactor Nano One currently uses for its process looks small in front of the 20 m3 stainless steel reactor Johnson Matthey used to make LFP.

Geoffroy’s task is to retrofit that reactor and the rest of the Montreal facility to work with the process. The next step is to build a new factory next door to demonstrate the technology at a larger scale. While the two plants will be substantial, they will largely serve as a blueprint for still-larger plants Nano One wants to build through joint ventures or licensing deals with bigger companies.

The Montreal plant was designed for an entirely different process, so scaling up will be a long road. Pointing to a hatch at the top of a large reactor, Geoffroy says testing the Nano One process may initially require dumping raw materials in by hand.

But Geoffroy points out that he, along with much of his team, went through this twice when they built a solid-state plant for Phostech and the hydrothermal plant for Süd-Chemie. The only difference now is that the size will be much bigger. “All the LFP made in North America commercially was really made here,” he says. “All that knowledge is there. We inherit that.”

The Massachusetts start-up 6K also wants to challenge established Chinese players with a cathode material manufacturing process that uses less energy and produces less waste.

“We have to leapfrog because we can’t compete directly with the same technology,” 6K CEO Aaron Bent says. In the US, “the workforce is more expensive, electricity is more expensive,” he says. “You’ve got to have a massively differentiated approach.”

6K’s approach involves injecting a precursor mixture containing lithium, iron, and phosphorus chemicals into a microwave plasma reactor that reaches 5,700 °C. The company says the heat and reactive ions in the plasma turn the precursors into a cathode material in a matter of seconds, eliminating the need for a kiln baking step, and most of the by-products can be recycled back into the process to reduce waste.

Like ICL, 6K received a DOE grant in October. Its research center can currently produce up to 400 t of cathode material annually, and the firm hopes to build a 10,000 t plant by 2026. 6K is also working with the US battery firm Our Next Energy to install LFP cathode production capacity at a cell factory in Michigan.

“We have to leapfrog because we can’t compete directly with the same technology.” Aaron Bent, CEO, 6K

Zaghib, the Concordia University battery scientist, is skeptical that new technology is the key to building an LFP ecosystem in North America. He says the solid-state process works well, and new technologies will struggle to match its price. “If we want to accelerate LFP we need GM, Ford . . . Tesla, or some government to start putting up money,” he says.

Ford hopes to partner with CATL to build LFP battery capacity locally, but in January, Virginia governor Glenn Youngkin said he had nixed a proposal for a CATL factory in his state, according to the Virginia Mercury. For now, Ford and other carmakers will rely on batteries produced in China.


The companies planning to make LFP materials in North America are betting that the lower cost of LFP-powered cars will help overcome US consumers’ anxieties about their limited range, but that’s far from a guarantee. US drivers love road trips and SUVs, which typically require large-capacity batteries.

“Our driving patterns are so different from what you see in Asia and in Europe,” says Michael Sanders, a battery industry analyst with Avicenne Energy. “I think range anxiety is going to play a much bigger role here in North America.”

There are several ways around the problem. CATL and BYD Auto, another Chinese battery maker, have engineered their LFP battery packs to be hyperefficient, increasing capacity by cramming extra cathode material into the same amount of space. Ford wants to use that technology in its LFP vehicles.

It’s also possible to use a combination of battery chemistries. Our Next Energy hopes to combine a primary LFP battery suitable for everyday use with a small lithium-metal battery that could boost a car’s range when needed. Lithium-metal batteries carry more energy than other battery chemistries, but they have yet to be commercialized, in part because they degrade after a small number of charge-discharge cycles.

Another approach is simply to make iron-based batteries better. That’s what the California start-up Mitra Chem is trying to do. The company uses machine learning to create new cathode materials that combine iron with other metals, such as manganese, to increase the energy density. “We ultimately want to get to . . . LFP 2.0, LFP 3.0, higher-energy-density products that can compete . . . with nickel,” says Vivas Kumar, cofounder and CEO of Mitra Chem.

Despite LFP’s lower energy density, many analysts, including Sanders, say technology improvements and low costs mean the battery chemistry will find a place in North America. BloombergNEF says there were no US cars powered by LFP in 2020, but it expects demand for LFP-powered cars to exceed 160 GW h by the end of the decade, representing 40% of the total demand for electric cars.

When those data were published in September 2022, only a handful of companies had announced plans to build LFP factories in the US. Several have since stepped up, and Yayoi Sekine, head of energy storage at BloombergNEF, says she thinks more will come, especially as the Inflation Reduction Act encourages battery makers to build a US supply chain.

Geoffroy remembers when demand for LFP-powered cars was near zero in North America. About 10 years ago, when he was working at one of Phostech’s early plants, he decided to buy something made with LFP from his facility. Unfortunately, a car wasn’t an option. “I bought some small LFP batteries to power my electric trolling motor when I go fishing,” he says. “So I’m powered by LFP.”

As Nano One and other companies start building LFP factories in North America, Geoffroy is hoping for something more substantial. The moment a car built with LFP from his facility becomes available, he’s going to buy it.

Renewable Energy’s Climb to the Top: Five Major Types of Renewable Energy & Their Potential Impact

The Renewable Energy Age

Awareness around climate change is shaping the future of the global economy in several ways.

Governments are planning how to reduce emissions, investors are scrutinizing companies’ environmental performance, and consumers are becoming conscious of their carbon footprints. But no matter the stakeholder, energy generation and consumption from fossil fuels is one of the biggest contributors to emissions.

Therefore, renewable energy sources have never been more top-of-mind than they are today.

The Five Types of Renewable Energy

Renewable energy technologies harness the power of the sun, wind, and heat from the Earth’s core, and then transforms it into usable forms of energy like heat, electricity, and fuel.

The above infographic uses data from LazardEmber, and other sources to outline everything you need to know about the five key types of renewable energy:Energy Source% of 2021 Global Electricity GenerationAvg. levelized cost of energy per MWhHydro 💧 15.3%$64Wind 🌬 6.6%$38Solar ☀️ 3.7%$36Biomass 🌱 2.3%$114Geothermal ♨️ <1%$75

Editor’s note: We have excluded nuclear from the mix here, because although it is often defined as a sustainable energy source, it is not technically renewable (i.e. there are finite amounts of uranium).

Though often out of the limelight, hydro is the largest renewable electricity source, followed by wind and then solar.

Together, the five main sources combined for roughly 28% of global electricity generation in 2021, with wind and solar collectively breakingthe 10% share barrier for the first time.

The levelized cost of energy (LCOE) measures the lifetime costs of a new utility-scale plant divided by total electricity generation. The LCOE of solar and wind is almost one-fifth that of coal ($167/MWh), meaning that new solar and wind plants are now much cheaper to build and operate than new coal plants over a longer time horizon.

With this in mind, here’s a closer look at the five types of renewable energy and how they work.

1. Wind

Wind turbines use large rotor blades, mounted at tall heights on both land and sea, to capture the kinetic energy created by wind.

When wind flows across the blade, the air pressure on one side of the blade decreases, pulling it down with a force described as the lift. The difference in air pressure across the two sides causes the blades to rotate, spinning the rotor.

The rotor is connected to a turbine generator, which spins to convert the wind’s kinetic energy into electricity

2. Solar (Photovoltaic)

Solar technologies capture light or electromagnetic radiation from the sun and convert it into electricity.

Photovoltaic (PV) solar cells contain a semiconductor wafer, positive on one side and negative on the other, forming an electric field. When light hits the cell, the semiconductor absorbs the sunlight and transfers the energy in the form of electrons. These electrons are captured by the electric field in the form of an electric current.

A solar system’s ability to generate electricity depends on the semiconductor material, along with environmental conditions like heat, dirt, and shade.

3. Geothermal

Geothermal energy originates straight from the Earth’s core—heat from the core boils underground reservoirs of water, known as geothermal resources.

Geothermal plants typically use wells to pump hot water from geothermal resources and convert it into steam for a turbine generator. The extracted water and steam can then be reinjected, making it a renewable energy source.

4. Hydropower

Similar to wind turbines, hydropower plants channel the kinetic energy from flowing water into electricity by using a turbine generator.

Hydro plants are typically situated near bodies of water and use diversion structures like dams to change the flow of water. Power generation depends on the volume and change in elevation or head of the flowing water.

Greater water volumes and higher heads produce more energy and electricity, and vice versa.

5. Biomass

Humans have likely used energy from biomass or bioenergy for heat ever since our ancestors learned how to build fires.

Biomass—organic material like wood, dry leaves, and agricultural waste—is typically burned but considered renewable because it can be regrown or replenished. Burning biomass in a boiler produces high-pressure steam, which rotates a turbine generator to produce electricity.

Biomass is also converted into liquid or gaseous fuels for transportation. However, emissions from biomass vary with the material combusted and are often higher than other clean sources.

When Will Renewable Energy Take Over?

Despite the recent growth of renewables, fossil fuels still dominate the global energy mix.

Most countries are in the early stages of the energy transition, and only a handful get significant portions of their electricity from clean sources. However, the ongoing decade might see even more growth than recent record-breaking years.

The IEA forecasts that, by 2026, global renewable electricity capacity is set to grow by 60% from 2020 levels to over 4,800 gigawatts—equal to the current power output of fossil fuels and nuclear combined. So, regardless of when renewables will take over, it’s clear that the global energy economy will continue changing.

Artificial Intelligence (AI) Discovers New Nanostructures – Brookhaven Center for Functional Nanomaterials

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have successfully demonstrated that autonomous methods can discover new materials.

The artificial intelligence (AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind nanoscale “ladder.” The research was published today in Science Advances.

The newly discovered structures were formed by a process called self-assembly, in which a material’s molecules organize themselves into unique patterns. Scientists at Brookhaven’s Center for Functional Nanomaterials (CFN) are experts at directing the self-assembly process, creating templates for materials to form desirable arrangements for applications in microelectronics, catalysis, and more. Their discovery of the nanoscale ladder and other new structures further widens the scope of self-assembly’s applications.

“Self-assembly can be used as a technique for nanopatterning, which is a driver for advances in microelectronics and computer hardware,” said CFN scientist and co-author Gregory Doerk. “These technologies are always pushing for higher resolution using smaller nanopatterns. You can get really small and tightly controlled features from self-assembling materials, but they do not necessarily obey the kind of rules that we lay out for circuits, for example. By directing self-assembly using a template, we can form patterns that are more useful.”

Staff scientists at CFN, which is a DOE Office of Science User Facility, aim to build a library of self-assembled nanopattern types to broaden their applications. In previous studies, they demonstrated that new types of patterns are made possible by blending two self-assembling materials together.

“The fact that we can now create a ladder structure, which no one has ever dreamed of before, is amazing,” said CFN group leader and co-author Kevin Yager. “Traditional self-assembly can only form relatively simple structures like cylinders, sheets, and spheres. But by blending two materials together and using just the right chemical grating, we’ve found that entirely new structures are possible.”

Blending self-assembling materials together has enabled CFN scientists to uncover unique structures, but it has also created new challenges. With many more parameters to control in the self-assembly process, finding the right combination of parameters to create new and useful structures is a battle against time. To accelerate their research, CFN scientists leveraged a new AI capability: autonomous experimentation.

In collaboration with the Center for Advanced Mathematics for Energy Research Applications (CAMERA) at DOE’s Lawrence Berkeley National Laboratory, Brookhaven scientists at CFN and the National Synchrotron Light Source II (NSLS-II), another DOE Office of Science User Facility at Brookhaven Lab, have been developing an AI framework that can autonomously define and perform all the steps of an experiment. CAMERA’s gpCAM algorithm drives the framework’s autonomous decision-making. The latest research is the team’s first successful demonstration of the algorithm’s ability to discover new materials.

“gpCAM is a flexible algorithm and software for autonomous experimentation,” said Berkeley Lab scientist and co-author Marcus Noack. “It was used particularly ingeniously in this study to autonomously explore different features of the model.”

“With help from our colleagues at Berkeley Lab, we had this software and methodology ready to go, and now we’ve successfully used it to discover new materials,” Yager said. “We’ve now learned enough about autonomous science that we can take a materials problem and convert it into an autonomous problem pretty easily.”

To accelerate materials discovery using their new algorithm, the team first developed a complex sample with a spectrum of properties for analysis. Researchers fabricated the sample using the CFN nanofabrication facility and carried out the self-assembly in the CFN material synthesis facility.

“An old school way of doing material science is to synthesize a sample, measure it, learn from it, and then go back and make a different sample and keep iterating that process,” Yager said. “Instead, we made a sample that has a gradient of every parameter we’re interested in. That single sample is thus a vast collection of many distinct material structures.”

Then, the team brought the sample to NSLS-II, which generates ultrabright X-rays for studying the structure of materials. CFN operates three experimental stations in partnership with NSLS-II, one of which was used in this study, the Soft Matter Interfaces (SMI) beamline.

“One of the SMI beamline’s strengths is its ability to focus the X-ray beam on the sample down to microns,” said NSLS-II scientist and co-author Masa Fukuto. “By analyzing how these microbeam X-rays get scattered by the material, we learn about the material’s local structure at the illuminated spot. Measurements at many different spots can then reveal how the local structure varies across the gradient sample. In this work, we let the AI algorithm pick, on the fly, which spot to measure next to maximize the value of each measurement.”

As the sample was measured at the SMI beamline, the algorithm, without human intervention, created of model of the material’s numerous and diverse set of structures. The model updated itself with each subsequent X-ray measurement, making every measurement more insightful and accurate.

In a matter of hours, the algorithm had identified three key areas in the complex sample for the CFN researchers to study more closely. They used the CFN electron microscopy facility to image those key areas in exquisite detail, uncovering the rails and rungs of a nanoscale ladder, among other novel features.

From start to finish, the experiment ran about six hours. The researchers estimate they would have needed about a month to make this discovery using traditional methods.

“Autonomous methods can tremendously accelerate discovery,” Yager said. “It’s essentially ‘tightening’ the usual discovery loop of science, so that we cycle between hypotheses and measurements more quickly. Beyond just speed, however, autonomous methods increase the scope of what we can study, meaning we can tackle more challenging science problems.”

“Moving forward, we want to investigate the complex interplay among multiple parameters. We conducted simulations using the CFN computer cluster that verified our experimental results, but they also suggested how other parameters, such as film thickness, can also play an important role,” Doerk said.

The team is actively applying their autonomous research method to even more challenging material discovery problems in self-assembly, as well as other classes of materials. Autonomous discovery methods are adaptable and can be applied to nearly any research problem.

“We are now deploying these methods to the broad community of users who come to CFN and NSLS-II to conduct experiments,” Yager said. “Anyone can work with us to accelerate the exploration of their materials research. We foresee this empowering a host of new discoveries in the coming years, including in national priority areas like clean energy and microelectronics.”

DNA Nanotechnology Tools: From Design to Applications

DNA nanostructures with their potential for cell and tissue permeability, biocompatibility, and high programmability at the nanoscale level are promising candidates as new types of drug delivery vehicles, highly specific diagnostic devices, and tools to decipher how biomolecules dynamically change their shapes, and interact with each other and with candidate drugs. Wyss Institute researchers are providing a suite of diverse, multifunctional DNA nanotechnological tools with unique capabilities and potential for a broad range of clinical and biomedical research areas.

DNA nanotechnological devices for therapeutic drug delivery

DNA nanostructures have future potential to be widely used to transport and present a variety of biologically active molecules such as drugs and immune-enhancing antigens and adjuvants to target cells and tissues in the human body.

DNA origami as high-precision delivery components of cancer vaccines

The Wyss Institute has developed cancer vaccines to improve immunotherapies. These approaches use implantable or injectable biomaterial-based scaffolds that present tumor-specific antigens, and biomolecules that attract dendritic immune cells (DCs) into the scaffold, and activate them so that after their release they can orchestrate anti-tumor T cell responses against tumors carrying the same antigens. To be activated most effectively, DCs likely need to experience tumor antigens and immune-boosting CpG adjuvant molecules at particular ratios (stoichiometries) and configurations that register with the density and distribution of receptor molecules on their cell surface.

Specifically developed DNA origami, programmed to assemble into rigid square-lattice blocks that co-present tumor antigens and adjuvants to DCs within biomaterial scaffolds with nanoscale precision have the potential to boost the efficacy of therapeutic cancer vaccines, and can be further functionalized with anti-cancer drugs.

Chemical modification strategy to protect drug-delivering DNA nanostructures

DNA nanostructures such as self-assembling DNA origami are promising vehicles for the delivery of drugs and diagnostics. They can be flexibly functionalized with small molecule and protein drugs, as well as features that facilitate their delivery to specific target cells and tissues. However, their potential is hampered by their limited stability in the body’s tissues and blood. To help fulfill the extraordinary promise of DNA nanostructures, Wyss researchers developed an easy, effective and scalable chemical cross-linking approach that can provide DNA nanostructures with the stability they need as effective vehicles for drugs and diagnostics.

In two simple cost-effective steps, the Wyss’ approach first uses a small-molecule, unobtrusive neutralizing agent, PEG-oligolysine, that carries multiple positive charges, to cover DNA origami structures. In contrast to commonly used Mg2+ions that each neutralize only two negative changes in DNA structures, PEG-oligolysine covers multiple negative charges at one, thus forming a stable “electrostatic net,” which increases the stability of DNA nanostructures about 400-fold. Then, by applying a chemical cross-linking reagent known as glutaraldehyde, additional stabilizing bonds are introduced into the electrostatic net, which increases the stability of DNA nanostructures by another 250-fold, extending their half-life into a range that is compatible with a broad range of clinical applications.

DNA nanotechnological devices as ultrasensitive diagnostic and analytical tools

The generation of detectable DNA nanostructures in response to a disease or pathogen-specific nucleic acids, in principle, offers a means for highly effective biomarker detection in diverse samples. A single molecule binding event of a synthetic oligonucleotide to a target nucleic acid can nucleate the creation of much larger structures by the cooperative assembly of smaller synthetic DNA units like DNA tiles or bricks into larger structures that then can be visualized in simple laboratory assays. However, a central obstacle to these approaches is the occurrence of (1) non-specific binding and (2) non-specific nucleation events in the absence of a specific target nucleic acid which can lead to false-positive results. Wyss DNA nanotechnologists have developed two separately applicable but combinable solutions for these problems.

Digital counting of biomarker molecules with DNA nanoswitch catenanes

To enable the initial detection (binding) of biomarkers with ultra-high sensitivity and specificity, Wyss researchers have developed a type of DNA nanoswitch that, designed as a larger catenane (Latin catenameaning chain), is assembled from mechanically interlocked ring-shaped substructures with specific functionalities that together enable the detection and counting of single biomarker molecules. In the “DNA Nanoswitch Catenane” structure, both ends of a longer synthetic DNA strand are linked to two antibody fragments that each specifically bind different parts of the same biomarker molecule of interest, thus allowing for high target specificity and sensitivity.

This bridging-event causes the strand to close into a “host ring,” which it is interlocked at different regions with different “guest rings.” Closing of the host ring switches the guest rings into a configuration that allows the synthesis of a new DNA strand. The newly synthesized diagnostic strand then can be unambiguously detected as a single digital molecule count, while disrupting the antibody fragment/biomarker complex starts a new biomarker counting cycle. Both, the target binding specificity and the synthesis of a target-specific DNA strand also enable the combination of multiple DNA nanoswitch catenanes to simultaneously count different biomarker molecules in a single multiplexed reaction.

For ultrasensitive diagnostics, it is desirable to have the fastest amplification and the lowest rate of spurious nucleation. DNA nanotechnology approaches have the potential to deliver this in an enzyme-free, low-cost manner.


A rapid amplification platform for diverse biomarkers

A rapid, low-cost and enzyme-free detection and amplification platform avoids non-specific nucleation and amplification and allows the self-assembly of much larger micron-scale structures from a single seed in just minutes. The method, called “Crisscross Nanoseed Detection” enables the ultra-cooperative assembly of ribbons starting from a single biomarker binding event. The micron-scale structures are densely woven from single-stranded “DNA slats,” whereby an inbound slat snakes over and under six or more previously captured slats on a growing ribbon end in a “crisscross” manner, forming weak but highly-specific interactions with its interacting DNA slats. The nucleation of the assembly process is strictly target-seed specific and the assembly can be carried out in a one-step reaction in about 15 minutes without the addition of further reagents, and over a broad range of temperatures. Using standard laboratory equipment, the assembled structures then can be rapidly visualized or otherwise detected, for example, using high-throughput fluorescence plate reader assays.



Crisscross Nanoseed Detection: Nanotechnology-Powered Infectious Disease Diagnostics

Enzyme-free DNA nanotechnology for rapid, ultrasensitive, and low-cost detection of infectious disease biomarkers with broad accessibility in point-of-care settings.

The DNA assembly process in the Crisscross Nanoseed Detection method can also be linked to the action of DNA nanoswitch catenanes that highly specifically detect a biomarker molecule leading to preservation of a molecular record. Each surviving record can nucleate the assembly of a crisscross nanostructure, combining high-specificity binding with amplification for biomarker detection.

Wyss researchers are currently developing the approach as a multiplexable low-cost diagnostic for the COVID-19 causing SARS-CoV-2 virus and other pathogens that could give accurate results faster and at lower costs than currently used techniques.

Nanoscale devices for determining the structure and identity of proteins at the single-molecule level

The ability to identify and quantify proteins from trace biological samples would have a profound impact on both basic research and clinical practice, from monitoring changes in protein expression within individual cells, to enabling the discovery of new biomarkers of disease. Furthermore, the ability to also determine their structures and interactions would open up new avenues for drug discovery and characterization. Over the past decades, developments in DNA analysis and sequencing have unquestionably revolutionized medicine – yet equivalent developments for protein analysis have remained a challenge. While methods such as mass spectrometry for protein identification, and cryoEM for structure determination have rapidly advanced, challenges remain regarding resolution and the ability to work with trace heterogeneous samples.

To help meet this challenge, researchers at the Wyss Institute have developed a new approach that combines DNA nanotechnology with single-molecule manipulation to enable the structural identification and analysis of proteins and other macromolecules. “DNA Nanoswitch Calipers” (DNCs) offer a high-resolution approach to “fingerprint proteins” by measuring distances and determining geometries within single proteins in solution. DNCs are nanodevices designed to measure distances between DNA handles that have been attached to target molecules of interest. DNC states can be actuated and read out using single-molecule force spectroscopy, enabling multiple absolute distance measurements to be made on each single-molecule.

DNCs could be widely adapted to advance research in different areas, including structural biology, proteomics, diagnostics and drug discovery.

All technologies are in development and available for industry collaborations.

Nanoplastics unexpectedly produce reactive oxidizing species when exposed to light

Plastics are ubiquitous in our society, found in packaging and bottles as well as making up more than 18% of solid waste in landfills. Many of these plastics also make their way into the oceans, where they take up to hundreds of years to break down into pieces that can harm wildlife and the aquatic ecosystem.

A team of researchers, led by Young-Shin Jun, Professor of Energy, Environmental & Chemical Engineering in the McKelvey School of Engineering at Washington University in St. Louis, analyzed how light breaks down polystyrene, a nonbiodegradable plastic from which packing peanuts, DVD cases and disposable utensils are made. In addition, they found that nanoplastic particles can play active roles in environmental systems. In particular, when exposed to light, the nanoplastics derived from polystyrene unexpectedly facilitated the oxidation of aqueous manganese ions and the formation of manganese oxide solids that can affect the fate and transport of organic contaminants in natural and engineering water systems.

The research, published in ACS Nanoon Dec. 27, 2022, showed how the photochemical reaction of nanoplastics through light absorption generates peroxyl and superoxide radicals on nanoplastic surfaces, and initiates oxidation of manganese into manganese oxide solids.

“As more plastic debris accumulates in the natural environment, there are increasing concerns about its adverse effects,” said Jun, who leads the Environmental Nanochemistry Laboratory. “However, in most cases, we have been concerned about the roles of the physical presence of nanoplastics rather than their active roles as reactants. We found that such small plastic particles that can more easily interact with neighboring substances, such as heavy metals and organic contaminants, and can be more reactive than we previously thought.”

Jun and her former student, Zhenwei Gao, who earned a doctorate in environmental engineering at WashU in 2022 and is now a postdoctoral scholar at the University of Chicago, experimentally demonstrated that the different surface functional groups on polystyrene nanoplastics affected manganese oxidation rates by influencing the generation of the highly reactive radicals, peroxyl and superoxide radicals. The production of these reactive oxygen species from nanoplastics can endanger marine life and human health and potentially affects the mobility of the nanoplastics in the environment via redox reactions, which in turn might negatively impact their environmental remediation.

The team also looked at the size effects of polystyrene nanoplastics on manganese oxidation, using 30 nanometer, 100 nanometer and 500 nanometer particles. The two larger-sized nanoparticles took longer to oxidize manganese than the smaller particles. Eventually, the nanoplastics will be surrounded by newly formed manganese oxide fibers, which can make them easily aggregated and can change their reactivities and transport.

“The smaller particle size of the polystyrene nanoplastics may more easily decompose and release organic matter because of their larger surface area,” Jun said. “This dissolved organic matter may quickly produce reactive oxygen species in light and facilitate manganese oxidation.” 

“This experimental work also provides useful insights into the heterogeneous nucleation and growth of manganese oxide solids on such organic substrates, which benefits our understanding of manganese oxide occurrences in the environment and engineered materials syntheses,” Jun said. “These manganese solids are excellent scavengers of redox-active species and heavy metals, further affecting geochemical element redox cycling, carbon mineralization and biological metabolisms in nature.”

Jun’s team plans to study the breakdown of diverse common plastic sources that can release nanoplastics and reactive oxidizing species and to investigate their active roles in the oxidation of transition and heavy metal ions in the future.null

New Sodium-Sulfur Battery is cheaper than lithium-ion with 4X the Capacity

It could help solve the renewable energy storage problem.

A new type of low-cost battery could help solve the renewable energy storage problem, giving us a better way to bank solar and wind energy for when the sun isn’t shining and the wind isn’t blowing.

The challenge: A whopping 30% of global CO2 emissions are produced by coal-fired power plants, and decarbonizing the electric grid is a vital part of combating climate change.

We can speed the transition to a clean electric grid by storing excess energy in batteries, but lithium-ion ones are expensive.

Solar and wind power have become dramatically cheaper over the past couple of decades. However, these sources still depend on environmental conditions — without wind, turbines can’t spin, and if the sun isn’t shining, solar panels (usually) can’t harvest energy.null

That makes these sources less consistent than fossil fuels, which can be dispatched on demand, and so even while solar and wind continue to grow, utilities continue to rely on gas to fill gaps and keep the electric grid stable.

Energy storage: We can speed the transition to renewable power by storing excess energy in batteries and then deploying it when the sun and wind aren’t cooperating with demand. Many newer renewable energy plants are being paired with big banks of lithium-ion batteries, but lithium is expensive, and mining it is bad for the environment in other ways.

“Storage solutions that are manufactured using plentiful resources like sodium … have the potential to guarantee greater energy security.”SHENLONG ZHAO

Room-temperature sodium-sulfur (RT Na-S) batteries are a promising alternative for renewable energy storage. They rely on chemical reactions between a sulfur cathode and a sodium anode to store and deploy electrical energy, and they use low-cost materials, which can even be easily extracted from saltwater.null

“Storage solutions that are manufactured using plentiful resources like sodium … have the potential to guarantee greater energy security more broadly and allow more countries to join the shift towards decarbonisation,” said Shenlong Zhao, an energy storage researcher at the University of Sydney.

What’s new? Existing RT Na-S batteries have had limited storage capacity and a short life cycle, which has held back their commercialization, but there’s now a new kind of RT Na-S battery, developed by Zhao’s team.

According to their paper, the device has four times the storage capacity of a lithium-ion battery and an ultra-long life — after 1,000 cycles, it still retained about half of its capacity, which the researchers claim is “unprecedented.”

“This is a significant breakthrough for renewable energy development.”SHENLONG ZHAO

This leap was possible thanks to the incorporation of carbon-based electrodes and the use of a process called “pyrolysis” to improve the reactivity of the sulfur and the reactions between the sulfur and sodium.null

“This is a significant breakthrough for renewable energy development which, although reduces costs in the long term, has had several financial barriers to entry,” said Zhao.

The big picture: So far, the Sydney researchers have only created and tested lab-scale versions of their RT Na-S battery. They now plan to focus on scaling up and commercializing the tech, which will likely take several years.

There are many other alternatives to lithium-ion batteries that can be used for renewable energy storage today, though, including long-living flow batteries, massive water batteries, and batteries that store electricity as heat in bricks, sand, and other solid materials.

The sooner we scale up our use of renewables and deploy more of these batteries — and innovative newcomers, like the University of Sydney’s creation — the better our chances of avoiding the worst possible effects of climate change.

New Solid State (Read Safer) Battery Holds More Energy and Maintains Capacity Even After Multiple Charging Cycles (And Will Cost Less)

Charging in five minutes? Almost the same as filling up your gas tank! Image Credit: Blue Planet

Scientists claim to have created a new type of battery that does not lose capacity after charging cycles, according to new research. The positive electrode material could pave the way for new electric car batteries that don’t suffer one of the greatest problems such cars currently face, which is a constantly diminishing lifespan and subsequently, expensive and ecologically-damaging replacements. 

If the world is going to be free of the crude oil chains that currently prevent us from becoming net zero, we must move away from the use of petrol and diesel cars. Generally considered our best bet in doing so is electric cars, which have come a long way in just a few years, but continue to be limited by battery technology. Lithium-ion batteries are heavy, expensive, relatively short-lived, and don’t offer the range needed to persuade many petrol-heads away from their beloved pistons. Not to mention some of the horrifying Safety Headlines in the news lately! If the world is to adopt electric cars, battery lifespans and much improved safety need to go up and costs need to go down. 

Enter solid-state batteries (SSBs), a promising new tech that may do just that. Lithium-ion batteries rely on a liquid electrolyte to facilitate the flow of charged ions during charging and discharging, while solid-state batteries are made of entirely solid materials. These batteries can:

  • Charge Faster,
  • Don’t pose a safety risk if the contents spill out, and
  • Can store more energy than their liquid counterparts

So … too good to be true, right? What’s the catch? Well … SSB’s are currently limited by the damage that occurs to the electrodes when lithium ions move through them. This is because the electrodes expand and shrink with ion movement as their structure changes, and if SSBs are to become viable, they need a way to stop this movement and the resulting damage. 

The Solution

To combat this, a team of researchers at Yokohama National University looked at a new type of SSB material that has incredible stability, preventing electrode damage. This material is useful for one main reason: it has the same volume when ions move out of or into it. Therefore, the battery can be used over and over without regular degradation of the material – technically, it could be charged and discharged indefinitely.

The team tested it and found no degradation across 400 charge/discharge cycles, which you certainly wouldn’t get with lithium-ion batteries. It isn’t quite perfect yet, but lead author Professor Naoaki Yabuuchi believes they are on track to make it so. (Yokohama National University)

“The absence of capacity fading over 400 cycles clearly indicates the superior performance of this material compared with those reported for conventional all-solid-state cells with layered materials,” co-author Associate Professor Neeraj Sharma said in a statement

“This finding could drastically reduce battery costs. The development of practical high-performance solid-state batteries can also lead to the development of advanced electric vehicles.” 

According to the team, this battery could mean an electric vehicle that charges in just five minutes, with higher capacity than current batteries – all at a much cheaper cost.  

The research was published in Nature Materials.

WARNING! AI-armed cyberattacks may become lethal in just 5 years from now

A recent cyber analytical report has warned that artificial intelligence (AI) enabled cyberattacks which are quite limited until now, may get more aggressive in the coming years.

The Helsinki-based cybersecurity and privacy firm WithSecure, the Finnish Transport and Communications Agency, and the Finnish National Emergency Supply Agency collaborated on the report, according to an article by Cybernews on Thursday.

AI-powered assaults will definitely excel at impersonation, a tactic utilized frequently in phishing, as per the study.

“Although AI-generated content has been used for social engineering purposes, AI techniques designed to direct campaigns, perform attack steps, or control malware logic have still not been observed in the wild, said Andy Patel WithSecure intelligence researcher.

Such “techniques will be first developed by well-resourced, highly-skilled adversaries, such as nation-state groups.” 

AI-armed cyberattacks may get lethal in next 5 years, warns report

The paper examined current trends and advancements in AI, cyberattacks, and areas where the two intersect, suggesting early adoption and evolution of preventative measures were key to overcoming the threats. 

“After new AI techniques are developed by sophisticated adversaries, some will likely trickle down to less-skilled adversaries and become more prevalent in the threat landscape,” stated Patel. 

The threat in the next five years

The authors claim that it is safe to assert that AI-based hacks are now extremely uncommon and mostly used for social engineering purposes. However, they are also employed in ways that analysts and researchers cannot directly observe. 

The majority of current AI disciplines do not come near to human intellect and cannot autonomously plan or carry out cyberattacks.

However, attackers will likely create AI in the next five years that can autonomously identify vulnerabilities, plan and carry out attack campaigns, use stealth to avoid defenses, and gather or mine data from infected systems or open-source intelligence.

“AI-enabled attacks can be run faster, target more victims and find more attack vectors than conventional attacks because of the nature of intelligent automation and the fact that they replace typically manual tasks,” said the report.

New methods are required to combat AI-based hacking that makes use of synthetic information, spoofs biometric authentication systems, and other upcoming capabilities, according to the paper. 

AI-powered deepfakes 

AI-powered assaults will definitely excel at impersonation, a tactic utilized frequently in phishing and vishing (voice phishing) cyberattacks, noted the report. 

“Deepfake-based impersonation is an example of new capability brought by AI for social engineering attacks,” claimed the report’s authors, who forecast that impersonations made possible by AI will advance further.

“No prior technology enabled to convincingly mimic the voice, gestures, and image of a target human in a manner that would deceive victims.” 

Many tech experts believe that deepfakes are the biggest cybersecurity concern. 

They have a strong shot at it because phone locks to bank accounts and passports, as well as all recent technical developments, have migrated toward biometric technologies.

Given how quickly deepfakes are developing, security systems that primarily rely on such technology appear to be at higher risk.

There were 1,291 data breaches until September 2021, according to the Identity Theft Resource Center’s (ITRC) study of data breaches. 

In comparison to data breaches in 2020, which totaled 1,108, this figure shows a 17 percent increase. 

281 million victims of data compromise were discovered during the first nine months of 2021, according to ITRC research, a sharp increase.

Scientists produce nanobodies in plant cells that block emerging pathogens

Scientists at the U.S. Department of Agriculture’s (USDA) Agricultural Research Service (ARS) recently announced that plants could be used to produce nanobodies that quickly block emerging pathogens in human medicine and agriculture. These nanobodies represent a promising new way to treat viral diseases, including SARS-CoV-2.

Nanobodies are small antibody proteins naturally produced in specific animals like camels, alpacas, and llamas.

ARS researchers turned to evaluating nanobodies to prevent and treat citrus greening disease in citrus trees. These scientists are now using their newly developed and patented SymbiontTM technology to show that nanobodies can be easily produced in a plant system with broad agricultural and public health applications.

As a proof-of-concept, researches showed that nanobodies targeting the SARS-CoV-2 virus could be made in plant cells and remain functional in blocking the binding of the SARS-CoV-2 spike protein to its receptor protein: the process responsible for initiating viral infection in human cells.

“We initially wanted to develop sustainable solutions to pathogens in crop production,” said ARS researcher Robert Shatters, Jr. “The results of that research are indeed successful and beneficial for the nation’s agricultural system. But now we are aware of an even greater result—the benefits of producing therapeutics in plants now justify the consideration of using plants to mass produce COVID-19 protein-based therapies.”

AgroSource, Inc. collaborated with USDA-ARS to develop the plant-based production system. They are currently taking the necessary steps to see how they can move this advancement into the commercial sector.

Smile and Learn for Kids (Older Folks Too)

“This is a huge breakthrough for science and innovative solutions to agricultural and public health challenges,” said ARS researcher Michelle Heck. “This cost-efficient, plant-based system proves that there are alternative ways to confront and prevent the spread of emerging pathogens. The approach has the potential to massively expand livelihood development opportunities in rural agricultural areas of the nation and in other countries.”

The findings are published on the bioRxiv preprint server.
