This 21-Year-Old Metro Atlanta Black Man Went Viral For Turning Plastic Into Fuel, Here’s How it Works

Thu, 29 May 2025 00:00:00 +0000

Atlanta native Julian Brown has launched an innovation as powerful as it is sustainable. Declaring a war on waste, this self-starter is working to turn pollution into power with his company, Naturejab. Intrigued by hands-on discovery early on, it’s no wonder he’s grasped the mechanics of Pyrolysis, recycling plastic waste into a fuel he calls “Plastidiesel.” “The very issue we have is the production of plastic,” Brown, 21, told The Root. “The reason why recycling hasn’t been done is because it hasn’t been profitable. But now, we are able to make a product of super high value out of something that otherwise is just seen as waste.” Brown isn’t just tooting his own horn either. The entrepreneur recently returned from a trip to Vancouver, Washington for the purpose of testing his recycled diesel with some heavyweights in fuel testing, ASAP Labs. His samples passed with flying colors on May 22, showing more favorable results than its industry competitors. “It looks like it definitely burned cleaner,” an employee at ASAP Labs confirmed in a documentation of the fuel’s results Friday. “It appears that this diesel probably burns cleaner than typical diesel.” According to Julian Brown, as long as he’s around, “there will be no such thing as plastic waste — only untapped energy.” With sky-high ambition rooted in his childhood and a deep sense of gratitude for how his journey has unfolded, Brown is stepping into his purpose on the world stage. And we’re here for it.

Blockchain Is The Next Big Thing For Renewable Energy

Sat, 27 Apr 2019 00:00:00 +0000

Blockchain has been touted as the next big technological advance. But what does it mean for renewable energy? Essentially an online register that securely stores information, blockchain serves as a repertoire of knowledge accessible to everyone. Rather than being controlled by one entity, blockchain is spread across multiple computers and uses a form of data logging to ensure that the information cannot be changed or corrupted. By decentralizing data and protecting the way it is manipulated, blockchain promotes transparency and the sharing of information. As such, the record has immense potential in helping shape a wave of new technology and our ability to interact with it. Blockchain is far more than just a platform for cryptocurrency. Many startups are already using blockchain as a tool to make energy grids more accessible and sustainable. The idea behind creating energy grids linked to blockchain is fairly simple: by giving consumers total control over where they source their energy as well as the information behind the production itself it drives competition and promotes sustainable energy. Consumers using a smart-grid that relies on blockchain will be able to compare their energy providers and buy directly from them. In Estonia, a blockchain-powered smart grid called WePower has been testing just how well a choice-driven energy market could work by teaming up with an independent energy provider who shares their energy data in real time.

Earth’s Underground Fungus Network Is So Gigantic That If You Stretched It Out, It Would Reach to Other Star Systems

Sun, 14 Jun 2026 00:00:00 +0000

Scientists have mapped the Earth’s entire underground fungal network, showing that it’s so extensive that if it were stretched into a straight line, it would reach other star systems — and span a sizable chunk of the Milky Way galaxy, for that matter. The groundbreaking work, published in a study in the journal Science, focused on microorganisms known as arbuscular mycorrhizal fungi. Forming the hidden backbone of our planet’s soil, they circulate water and nutrients and regulate the climate by locking away vast stores of carbon. Altogether, the global fungal network weighs around 300 megatons, the study found, which is four to six times more than the biomass of all human beings. Around 40 percent of that fungal mass resides in high-altitude or flooded grasslands, like the Everglades in Florida. The authors hope that their work will highlight the indispensable but overlooked role that these fungal networks play in the Earth’s ecosystems, with around 70 percent of all ground-based plant life depending on the fungi. In all, the model found that the planet is lined with more than 110 quadrillion kilometers of hyphae, or 68 quadrillion miles, which is almost a billion times the distance between the Earth and the Sun. On a cosmic ruler, that equals nearly 12,000 light years, or about a tenth the diameter of our galaxy. It’s the clearest picture yet of just how much fungal networks underpin our terrestrial ecosystems.

Mushrooms help remove sewage and E. coli from Devon River

Tue, 02 Jun 2026 00:00:00 +0000

Mushrooms could be used to filter out harmful waste and sewage in rivers, after a trial showed a certain fungi can destroy a type of bacteria that is a risk to human health. The fungi, called turkey tail mushroom, was used in part of a river in Devon and managed to filter out 80% of E. coli bacteria during the trial. During the trial, bags of turkey tail mushrooms were stacked across a riverbed, filtering water through their roots, which are called mycelia. The mycelia acted like a sponge, catching the E. coli bacteria to prevent it going into the river. Water industry regulator Ofwat has given Anglian Water £1.5 million to use fungi to clean up rivers because the trial worked so well. In another trial in Lincolnshire, a similar barricade caught 83% of phosphorus and 35% of nitrogen from rainwater running off farmers' fields. Farmers spread these chemicals as fertilisers, but when they wash into watercourses they can cause thick algae to form, starving fish of oxygen. The mushroom barriers could be placed near sewage overflow pipes to remove pollutants released during storms. Mushrooms can be used as a packaging material. Mycelium has been used by ... companies for packaging, because [it] breaks down naturally within weeks of use. And fashion designer Stella McCartney came up with a really fun-gi idea a few years ago. She created the first ever clothing made of mushroom leather, using the mycelium. Mushroom leather, unlike other fake leathers, is entirely natural and biodegradable.

Hemp for the future: here’s why one plant can change everything

Tue, 10 Jun 2025 00:00:00 +0000

Hemp – Cannabis sativa L. with a THC content low enough to avoid intoxication – has walked beside humanity for at least 10 millennia. The plant’s renaissance is ... a practical answer to converging crises in climate, resources, and rural economies. Hemp can be spun into linen-soft cloth, mixed into concrete—like blocks, brewed into nutty milk, pressed into nutritious oil, and refined into graphene—grade carbon nanosheets. It grows fast, sequesters more carbon per hectare than most forests, and asks for little more than sunlight, moderate rainfall, and room to stretch. Because every single part of the stalk, seed, leaf, and root can be transformed into something of value, hemp stands apart as a champion of circular design. Early drafts of the Declaration of Independence were [written on] linen-hemp blends. Hemp’s reputation suffered only when petro-synthetic fibers and anti-cannabis laws converged in the 1930s. Eighty years later, reforms from Canada to Australia to continental Europe have reopened fields once taken from the crop. Field trials in Ukraine and Italy show hemp’s phytoremediation power: the plant can bind or volatilize heavy metals such as cadmium and nickel while leaving fiber fractions safe for non-food applications. The plant synthesizes over a hundred other phytocannabinoids. Chief among them, CBD modulates serotonin receptors, calms epileptic seizures in Dravet syndrome, and shows promise in anxiety, pain, and inflammation trials.

Phone-Free Social Events Grew by 567% Led by the Generations Who Didn’t Have Them Until Adulthood

Thu, 30 Apr 2026 00:00:00 +0000

Members of Gen Z and Millennials are attending phone-free experiences 567% more often across the globe, signaling a major shift in how people want to gather. Eventbrite data shows that the generations having grown up with limited to no social media and smartphone use, and which then lead the charge to its ubiquitous adoption, is now leading the world back—away from constant connectivity. These events now span the full calendar year, signaling a shift from temporary reset to sustained behavior. The momentum is most pronounced in the US and UK, though each market reflects a distinct pattern of growth. The United Kingdom has emerged as the global leader for phone-free socializing, with events growing by 1,200% and attendance increasing by 1,441%. Of course the previous amount will have been very small, and ... the overall number of phone-free events will still be low in comparison to others. There is a strong focus in the UK on countering loneliness and social isolation. In the United States, the offline or analog movement is defined by expansive participation. While event volume grew by 388%, attendance jumped by 913%. The growth is already accelerating. In just the first three months of 2026, phone-free experiences have reached over a third of last year’s global event volume, signaling that this is no longer a fringe behavior, but a mainstream way of gathering.

‘We need to go places and touch things’: the people turning away from smartphones

Wed, 12 Jun 2024 00:00:00 +0000

Almost two decades after the first iPhone was released, a trend for lower tech devices appears to be taking shape, with a growing minority swapping their smartphones for “dumb phones”. With new models such as the Boring Phone, the trend is partly being fuelled by young people’s suspicion of the data- and attention-harvesting tech they have grown up with, as well as a bid to live more offline. And while smartphones are the obvious target for this trend, the “newtro” (a portmanteau of “new” and “retro”) movement is heralding a revival of analogue media, including cassettes and fanzines, against the backdrop of the enduring, and much-heralded, vinyl boom. While Jess Perriam, 39, had become exhausted by her Instagram feed, she knew she wanted to keep a window into the lives of others. So she turned to Postcrossing, a site that connects people who want to send and receive postcards from strangers around the world. “I still wanted to have that connection with people and learn more about different cultures, but not necessarily while being aggressively marketed at,” she said, adding that she receives “stacks of reading recommendations” through the post. The community has more than 800,000 members across 207 countries, with 77 million postcards received since it launched in 2005. As well as writing to people she has never met, she also corresponds with an old friend in the US. “It forces me to sit down and think, what do I want to communicate to my friend?”

Free Energy from the Vacuum? Warp Drive Pioneer Unveils Battery-Free ‘MicroSparc’ That Allegedly Draws Power from the Quantum Vacuum

Tue, 12 May 2026 00:00:00 +0000

Casimir Inc, a company founded and led by former DARPA-funded NASA warp drive pioneer and founder of the EagleWorks Lab, Harold G. “Sonny” White, has [announced] the pending 2028 commercialization of MicroSparc, a chip that the company claims uses customized microscale geometries to capture unlimited ‘free’ energy from the quantum world. “Think: no batteries, no cords, and no charging—just continuous power from harvested quantum vacuum fields,” a company spokesperson explained. In an email to The Debrief, Dr. White ... explained that MicroSparc’s use of customized Casimir cavities, which his team had researched with funding from the Defense Advanced Research Projects Agency (DARPA), does not violate the laws of physics. Instead, the noted advanced propulsion physics researcher said their MicroSparc design leverages 20th-century discoveries in quantum physics, such as quantum tunneling and Casimir cavities, to capture usable energy that could fuel small, low-power electronics in the near future. Its technology can potentially be scaled to power cars, homes, or even entire cities without the need for harmful fossil fuels or other greener, yet costly, fuel alternatives. Decades of research in quantum physics and mechanics have revealed that at the quantum level, the classically ‘empty’ vacuum is filled with “fluctuating electromagnetic fields and virtual particles that constantly appear and disappear.” White noted that the Casimir Effect, on which its company is based and for which it is named, provides clear proof of this quantum vacuum behavior. When asked if MicroSparc would constitute a “zero-point” energy device like those featured in science fiction ... Dr. White appeared to agree in general terms.

Note: The technology is based on the idea that empty space itself contains energy. Using advanced nanoscale engineering, background energy can be captured and converted into a continuous electrical current.

Four ways AI is being used to strengthen democracies worldwide

Sun, 23 Nov 2025 00:00:00 +0000

There are risks to democracy from AI, but there are also opportunities. AI is being used by some to make democracy better, stronger, and more responsive to people. CalMatters, a non-profit, non-partisan news organization. Since 2023, its Digital Democracy project has been collecting every public utterance of California elected officials – every floor speech, comment made in committee and social media post, along with their voting records, legislation, and campaign contributions – and making all that information available in a free online platform. CalMatters this year launched a new feature that takes this kind of civic watchdog function a big step further. Its AI Tip Sheets feature uses AI to search through all of this data, looking for anomalies, such as a change in voting position tied to a large campaign contribution. These anomalies appear on a webpage that journalists can access to give them story ideas and a source of data. This is not AI replacing human journalists; it is a civic watchdog organization. And it’s no coincidence that this innovation arose from a new kind of media institution – a non-profit news agency. AI technology is not without its costs and risks, and we are not here to minimize them. But the technology has significant benefits as well. AI is inherently power-enhancing, and it can magnify what the humans behind it want to do. It can enhance authoritarianism as easily as it can enhance democracy. It’s up to us to steer the technology in that better direction.

The Texting Network for the End of the World

Wed, 04 Jun 2025 00:00:00 +0000

Hypothetical: You wake up tomorrow morning to find [that] the internet has functionally ceased to exist. But you need to connect with people you trust to get help and survive. What do you do? Meshtastic is a program that enables devices to send text messages over long distances without needing Wi-Fi or cell service. Long range radio (LoRa) nodes help pass messages along, forming a network of devices that can talk to each other even in remote areas. Messages hop from device to device, with each node relaying messages it hasn't seen before—extending the network’s reach across miles using minimal power. That is to say, Meshtastic is designed specifically for sending text messages over free-to-use radio frequencies to both groups and individuals, even when cell service and internet connections are nowhere to be found. “The cool thing about Meshtastic is that it’s like a radio infrastructure without the infrastructure. It’s ad hoc,” says Eric Kristoff, a volunteer member of the Chicago chapter of the Mars Society. Meshtastic was created by technologist Kevin Hester in early 2020 as a way to communicate while doing “any hobby where you don’t have reliable internet access,” and it remains a grassroots endeavor, with established local communities spanning from Argentina to China that are ripe with a DIY ethos. The software itself is open source, meaning anyone can theoretically contribute, and hundreds have. A core group of volunteer developers helps maintain the Meshtastic firmware.

Marshall Islands launches world’s first universal basic income scheme offering cryptocurrency

Tue, 16 Dec 2025 00:00:00 +0000

The Marshall Islands has introduced a national universal basic income (UBI) scheme that offers payments via cryptocurrency, alongside more traditional methods, which experts say is the first scheme of its kind in the world. Every resident citizen of the Marshall Islands will receive quarterly payments of about US$200 as part of a government effort to ease cost of living pressures. The first instalments were paid in late November and recipients can choose whether the money is paid into a bank account, by cheque, or delivered as cryptocurrency on the blockchain through a government-backed digital wallet. “We the government want to make sure no one is left behind,” Marshall Islands’ minister for finance David Paul [said]. “$200 per person per quarter, which is about $800 a year, does not compel you to quit your job ... but it’s actually like a morale booster for people.” The UBI scheme is financed by a trust fund created under an agreement with the United States, which in part aims to compensate the Marshall Islands for decades of American nuclear testing. The cryptocurrency delivery option – which involves the transfer of a digital token known as a stablecoin, pegged to the US dollar – was designed to address the practical challenge of delivering the money across hundreds of remote islands. Anelie Sarana, the finance manager involved in the rollout, said ... many recipients were using the money immediately for basic needs, like food and essentials.

Digital Tools Are Fueling the Rise of New “Time Exchange” Solidarity Economies

Wed, 03 Dec 2025 00:00:00 +0000

In Kent, Ohio, older white women and immigrant families are forging unexpected connections through a time exchange network. Through time exchanges — sometimes called time banking — members earn time credits by helping others, then redeem them when they need assistance themselves. It’s not barter, or charity; time banking emphasizes reciprocal exchange, recognizing that everyone has something to offer, and that we all need help sometimes. With over 530 active members and more than 101,000 hours exchanged over the past 15 years, Kent’s time bank is one of the most vibrant in the world. Last year alone, members completed 3,900 exchanges through the original version of Time and Talents, a free platform. The ... interface is user-friendly. Users can track their time credit balance, and exchange private messages with each other about their needs and skills. Membership isn’t limited to individuals — art galleries, businesses, and even governmental groups have requested volunteer labor in exchange for time credits. Rather than defaulting as a nonprofit with a formal board, groups might experiment with open organizing models where anyone can participate. Madison-based organizer Stephanie Rearick ... helped start a time bank in 2005, after she learned about it as one economic system of many in a book called The Future of Money. “I realized that time banking should address the things in our economy that most need to be addressed ... such as the degradation and devaluation of care and creativity, civic engagement and community work.” Rearick sees common funds as one antidote to co-optation and collapse. Through them, neighbors pool money collectively to support shared projects and one another. After leaving the time exchange in 2017, she helped launch a common fund in 2022 as president of Humans United in Mutual Aid Networks (HUMANS), a global cooperative network focused on building a mutual aid economy. Time exchanges and common funds, she said, are just two tools of many that can be used for cultivating what she calls a neighborly economy.

The Native Seed Farm Safeguarding California’s Future

Mon, 16 Mar 2026 00:00:00 +0000

Heritage Growers, a native seed farm in Colusa founded by the nonprofit River Partners in 2021, is tackling one of the most fundamental — and least visible — environmental recovery challenges facing the American West: the shortage of locally adapted native seeds needed to restore damaged ecosystems at scale. With more than 200 acres in production, the farm grows what restoration scientists call “source-identified” seed — plant material whose genetic origin can be traced to the specific region where it will ultimately be replanted. That distinction is crucial. “It’s not just any seed,” says Heritage Growers’ general manager Pat Reynolds, a restoration ecologist with more than 30 years of experience. “You want to take material that comes from a specific region, track and make sure those genetics are held forward, produce that seed and put it back into the region. That’s a real important part of it. A poppy that’s grown out in China and came from who knows what is not appropriate for habitat restoration.” Some species require hand harvesting. Others, including some varieties of milkweed critical to pollinators like monarch butterflies, can cost more than $1,000 per pound to produce. “Milkweed actually is very expensive to amplify,” Reynolds explains. “But we need it because if there is no milkweed, there are no monarch butterflies.” Heritage Growers was created five years ago to address this systemic shortage.

How Community Solar Turned a Superfund Site into Savings in Illinois

Fri, 16 Jan 2026 00:00:00 +0000

Fredy Amador is intimately familiar with the financial struggles people face in the current economy. Northern Illinois’ skyrocketing energy bills make the situation even tougher. Now, Amador has become an evangelist for something that can provide a modest measure of relief: A community solar project, built on a Superfund site too polluted for much else in the city of Waukegan where he lives, about 40 miles north of Chicago. Residents who subscribe to get energy from the solar farm are guaranteed to see savings on their energy bills, under a state program incentivizing solar in low-income areas. The 9.1-megawatt Yeoman Solar Project, which went online last month, can provide energy for about 1,000 households, as well as the Waukegan school district, which owns the land. Such brownfields are attractive locations for solar installations because of “existing electrical infrastructure, lower-cost land, and community acceptance,” noted Paul Curran, CleanCapital’s chief development officer. Incentives from the state initiative Illinois Solar for All helped make the project financially viable, even given extra costs incurred from building on a Superfund site. Solar is a good fit for sites that are too polluted for housing or other types of development. Under the terms of the Superfund remediation, residential use is prohibited at the Yeoman Creek site. The company has developed solar on brownfields and landfills in other states, including a new 822-kilowatt site in Maryland.

This Breakthrough Sponge Could Change How the World Gets Clean Water

Sun, 06 Jul 2025 00:00:00 +0000

Most of the water on Earth is found in the oceans, but it’s far too salty to drink. While desalination plants can remove salt and make seawater drinkable, they typically use a lot of energy. Now, researchers have developed a promising new material that could change that. Reporting in ACS Energy Letters, a team of scientists created a sponge-like structure filled with long, microscopic air channels that harness sunlight to turn saltwater into fresh, clean water. In an outdoor test, this simple system—just the sponge and a clear plastic cover—successfully produced drinkable water using only natural sunlight. It’s a step toward making low-energy, sustainable desalination more accessible. In an outdoor test, the researchers placed the material in a cup containing seawater, and it was covered by a curved, transparent plastic cover. Sunlight heated the top of the spongy material, evaporating just the water, not the salt, into water vapor. The vapor collected on the plastic cover as liquid, moving the now clean water to the edges, where it dripped into a funnel and container below the cup. After 6 hours in natural sunlight, the system generated about 3 tablespoons of potable water. “Our aerogel allows full-capacity desalination at any size,” [researcher Xi] Shen says, “which provides a simple, scalable solution for energy-free desalination to produce clean water.”

An Unlikely Source of Crypto Innovation: Afghanistan

Sat, 24 Jan 2026 00:00:00 +0000

At a bustling money changer in northwestern Syria, a 46-year-old farmer gripped a plastic card like a lifeline. She had never heard of cryptocurrency, but the card held $500 of it to help restart her farm after nearly 14 years of civil war. Where had such technology come from, she asked. The answer surprised her: Afghanistan. Blockchain-based cash transfers are not the kind of innovation that many people would expect from a country better known for its repressive Taliban leadership, which views the internet with suspicion. But in a nation that has largely turned its back on the world, an Afghan start-up is building tools that it hopes will transform how humanitarian aid is delivered in countries shattered by conflict. “We’ve lived through these challenges ourselves, so we know how to develop an approach that works,” said Zakia Hussaini, 26, a programmer at the start-up, HesabPay, which designed the technology driving Ms. Almahmoud’s card. An early proponent of the platform was the United Nations High Commissioner for Refugees. The agency uses it to support more than 86,000 families in Afghanistan in one of the biggest public blockchain aid initiatives in the world. Mercy Corps, which donated the funds to Ms. Almahmoud, worked with HesabPay to expand its reach to include Syria, and programs for Sudan and Haiti are in development. Today, the platform has more than 650,000 wallets in Afghanistan, of which about 50,000 are in regular use.

‘Soil is more important than oil’: inside the perennial grain revolution

Fri, 12 Dec 2025 00:00:00 +0000

“These plants are the winners, the ones that get to pass their genes on [to future generations],” says Lee DeHaan of the Land Institute, an agricultural non-profit based in Salina, Kansas. If DeHaan’s breeding programme maintains its current progress, the descendant of these young perennial crop plants could one day usher in a wholesale revolution in agriculture. The plants are intermediate wheatgrass. Since 2010, DeHaan has been transforming this small-seeded, wild species into a high-yielding, domesticated grain crop called Kernza. He believes it will eventually be a viable – and far more sustainable – alternative to annual wheat, the world’s most widely grown crop and the source of one in five of all calories consumed by humanity. Remarkably, DeHaan does not paint the current agricultural-industrial complex as the enemy. “Every disruptive technology is always opposed by those being disrupted,” he says. “But if the companies [that make up] the current system can adjust to the disruption, they can play in that new world just the same.” The Land Institute’s strategy is redirection rather than replacement. “Our trajectory is to eventually get the resources that are currently dedicated to annual grain crops directed to developing varieties of perennials,” says DeHaan. “That’s our [route to] success.” There are signs that this is already working, with the food firm General Mills now incorporating Kernza into its breakfast cereals.

Ancient Indigenous ‘Songlines’ Match Long-Sunken Landscape off Australia

Tue, 02 Jan 2024 00:00:00 +0000

When marine geologist Mick O’Leary showed a group of Australian First Nations Elders a digital model of two ancient watering holes he had recently located—now under 14 meters of ocean—one man perked up, struggled to his feet and began speaking excitedly. Timmy Douglas, had recognized the watering holes as part of a songline he’d known all his life. Songlines involve using dramatic story songs that First Nations people began creating long before the written word as a mnemonic and spiritual system to navigate Australia’s harsh terrain: they would do so by singing the songs as they walked across the land. These songs, which also define groups and laws and impart cultural values, have been passed down from one generation to the next over thousands of years. The connection of the songline to a recent and remarkable archeological find by O’Leary and his colleagues illustrates how First Nations groups and modern scientists are learning to work together—in this case to find evidence of the ancient humans who lived on land that is now underwater, what the Murujuga Elders call “Sea Country.” Such evidence now includes stone tools that the scientists found last year on the ocean floor near the submerged watering holes. O’Leary says that although the research team did not physically follow the songline to make its discovery, he thinks that kind of collaboration might happen in the near future.

The City That Turns Human Waste into Clean Fuel

Thu, 27 Nov 2025 00:00:00 +0000

Every time somebody flushes a toilet in Mannheim, they contribute to ecological shipping. Since March 2025, the German city’s wastewater treatment plant has been feeding an experiment of global relevance: Transforming sewage gases into green methanol, a cleaner, nearly-carbon-neutral alternative to heavy fuel oil. The pilot, known as Mannheim 001, is the first full case study of how human waste can be captured, processed and converted into fuel powerful enough to propel cargo ships across oceans. “It’s the first time the entire value chain — from sewage to finished methanol — has been demonstrated,” says David Strittmatter, co-founder of Icodos, the start-up behind the project. Wastewater plants produce sludge — the thickened residue left after sewage is treated and cleaned. Mannheim’s plant ferments this sludge in oxygen-free tanks, yielding biogas rich in methane and carbon dioxide, which is usually burned for heat or flared off. Icodos’ innovation is to clean and upgrade that gas. “The sewage gas is dried, desulfurized, and then the carbon dioxide is separated from the rest,” Strittmatter explains. Using renewable electricity, the captured carbon dioxide is then combined with hydrogen through a catalytic process to form methanol — a liquid fuel that can run ship engines. According to Icodos, scaling sewage-to-methanol worldwide could cover the entire fuel demand of the global shipping sector.

Scientists Built a Computer Out of Shiitake Mushrooms—and It Works

Thu, 30 Oct 2025 00:00:00 +0000

Scientists have just built working computer components out of shiitake mushrooms. As described in a paper published in PLOS One, using mycelium—the threadlike roots of fungi—researchers created memristors, the circuitry elements that remember past electrical states. You’d imagine such a feat would yield a memristor that performs terribly, but the researchers say its performance wasn’t too far off from that inside your laptop. These organic circuits can store information, process signals, and maybe even help future computers behave more like organic brains, all while being low-cost, biodegradable, and probably compostable when you’re done with them. The team grew nine batches of shiitake mycelium in petri dishes. They let them sprawl and stretch into mildly disturbing, gross, tangled networks of roots. Then, they dried them out in the sunlight until they were ready to handle electricity. Once wired up to a circuit, the fungal fibers responded to voltage like living synapses. They were firing off signals at about 5,850 hertz with 90 percent accuracy. The researchers found they could boost power by wiring more mushrooms together, creating an even larger fungal network that improved circuit stability and speed. It’s still very early on, but the implications here are wild and potentially game-changing. Imagine being able to grow the components for, say, a new iPhone or the aforementioned high-end gaming rig, from just some dirt and a lot of humidity.

Fungi Are Becoming Invaluable First Responders in Eco-Crises

Thu, 02 Oct 2025 00:00:00 +0000

When Mount Saint Helens in southwestern Washington erupted on the morning of May 18, 1980, the stratovolcano spewed a plume of debris high into the earth’s atmosphere and spread ash to at least eleven nearby states. But despite the appearance of a mountain-side extinction event, life was already regenerating. Just 10 days after the eruption, the geomorphologist Fredrick Swanson surveyed one of the lahars with colleagues and noticed something intriguing. In the rubble, fine, filament-like threads had attached themselves to some of the smaller pebbles and stones cast out of the volcano’s center. What Swanson was witnessing was the phenomenon of “phoenicoid fungi,” aptly named in a nod to the mythical phoenix rising from the ashes. Fungal organisms such as these are often the first responders to blast zones and wildfire burn areas where the decomposing landscape serves as a smorgasbord for their biological needs. The fungi used for environmental clean-up come in a variety of shapes and sizes. Oyster mushrooms ... can break down petroleum and hydrocarbons, putting them top of the list when it comes to cleaning up deadly oil spills. A 2023 study conducted in Massachusetts, commissioned by MassDOT, found that there could be benefits to integrating mycelium into the state’s pre-existing stormwater management infrastructure to serve as a filtration system to improve water quality.

We’re Living in a Mushroom Kingdom

Mon, 29 Sep 2025 00:00:00 +0000

It wouldn’t be wrong to say Sam Shoemaker crossed the ocean on a mushroom. This August, the Californian artist launched his 14-foot kayak off Catalina Island and paddled for 12 hours across the 26.5-mile Catalina Channel to San Pedro. The brownish-white boat itself [was] “a boat made entirely from a single mushroom growing outside my studio,” Shoemaker explains — the world’s largest mushroom boat. He built it from wild Ganoderma polypore collected near his LA studio, propagated in a hemp-and-sawdust substrate for about four weeks, molded into kayak form and dried until it became “a strong, hydrophobic and inert, cork-like material.” Mycelium, the interconnected root network of a fungus such as Ganoderma polypore, can grow to hundreds of acres. The boat was sealed with locally sourced beeswax, using no synthetic materials. Shoemaker’s multiyear project wasn’t commercial — he is simply interested in demonstrating mushrooms’ potential. His invention is part of AquaFung, a term coined — and a movement inspired — by artist Phil Ross that hopes to one day replace Styrofoam and other materials that go into water with fungi, as part of the nonprofit Open Fung. In their quest, Shoemaker and Ross are members of a sprouting global community of artists, engineers, high-end designers and environmentalists, intent on producing sustainable inventions from mushrooms. For Ross, mycelium is not just a material but a mystery and companion.

‘Leave it to nature’: how enticing insects to kill off pests helped cut reliance on pesticides

Fri, 08 Aug 2025 00:00:00 +0000

While trying to come up with a pesticide solution to kill off bollworms, Dr Robert Mensah had his eureka moment. It was the 90s, and in Australia bollworms were devastating cotton farms. He experimented and eventually came up with a simple food spray, “a mixture of food ingredients, yeast and sugar-based, diluted in water and applied to crops. It emits an odour which is picked up by beneficial predatory insects and attracts them to the fields where they kill pests.” It was the beginning of an international grassroots campaign, in which Mensah has worked with various charities to teach people about this sustainable farming method. Ever since the dangerous side effects of pesticides became widely known, alternatives have been sought. This approach to farming, which reduces our reliance on pesticides, is called integrated pest management. In 2005, Mensah took food sprays to Benin, where the Pesticide Action Network (PAN UK) was helping farmers transition to organic farming. There, the misuse of chemical pesticides was seriously damaging people’s health. The food sprays – cheap, safe and effective – caught on with farmers in Benin where thousands now use the technique. From there, Mensah took food sprays to southern Ethiopia, where they were also trialled successfully on vegetables ... and then to Vietnam where they were used successfully on maize. Another charity, Better Cotton, is now trialling food sprays in India ... where they’ve trained 214,000 farmers to use sprays.

First 3D-Printed Home Made Primarily From Soil is Built in Japan–Ditching Unsustainable Concrete

Sat, 09 Aug 2025 00:00:00 +0000

Collaborating with robotics engineers and Italian 3D printer manufacturers, a Japanese company is building “homes of earth” made primarily from soil. Lib Work, Ltd. completed their first 3D-printed earth home in Yamaga, Kumamoto on July 22, calling their creative process “uncharted territory where tradition and convention offered no guide”. With an eye toward recycling, sustainability, and reduced carbon emissions, Lib Work focused on combining 3D-printing with natural materials enhanced for strength, constructibility, and design quality. The walls of the completed Lib Earth House Model B use no cement (which produces industrial waste). Instead, they utilized only naturally derived materials with soil as the primary component to create sustainable earthen walls. Compared to the previous model (Model A) that used some cement, the building’s strength has improved approximately fivefold while significantly reducing CO2 emissions from the manufacturing process itself. The walls contain cutting-edge sensors as part of a wall condensation monitoring system that monitors in real-time the temperature and humidity inside the walls. This system enables the house to manage its own condition by detecting condensation in advance to maintain a long-lasting, comfortable living environment. Additionally, the homes include remote operation of air conditioning, lighting, and bath controls via smartphone or dedicated monitor. It also features an off-grid energy system.

Big Insurance Uses AI to Quickly Deny Claims, One Man Fights Back with AI App That Quickly Appeals

Tue, 05 Aug 2025 00:00:00 +0000

The idea that American health insurance companies are using AI to analyze and adjudicate claims for approval or denial sounds terrifying, but one North Carolinian is using AI to fight back. When Raleigh resident Neal Shah had a claim denied for his wife’s chemotherapy drugs, he thought it was rare, that he was the only one, that it was just bad luck. Litigating his case on phone calls that lasted for hours changed the husband and father, and he set about creating a sophisticated app that uses artificial intelligence to compare claims denial forms against health insurance contracts, before automatically drafting an appeal letter. “For a doctor to write this, it’s not rocket science, but it still takes hours,” Shah told ABC News 11, adding that a well-written appeal letter, sent in immediately, can sometimes get denials reversed within days or weeks, but most people either don’t know they can appeal, or don’t know on what grounds they can appeal. In fact, according to Shah’s research, 850 million claims denials occur every year, and less than 1% are ever appealed. That’s where Counterforce Health comes in, a startup that’s created a free-to-use app for claims denials. For Counterforce Health, Shah brought onboard Riyaa Jadhav, a Jill of all trades who has helped grow and expand the undertaking. Together, they’ve built Counterforce to the point where it boasts a 70% success rate in appealing claims.

The good hacker: can Taiwanese activist turned politician Audrey Tang detoxify the internet?

Sat, 17 Aug 2024 00:00:00 +0000

Audrey Tang ... is determined that digital technology will once again become a force for good – a supreme listening tool for humanity, bringing us together by celebrating difference and uniting over what we have in common. Tang spent eight years in Taiwan’s government (the last two as the world’s first minister of digital affairs), putting her theory into practice – and it has worked, from a fantastically efficient response to Covid to countering misinformation about electoral fraud. In 2012, she was part of the digital community that created g0v, pronounced Gov Zero. The project ran in parallel with the official government and was there to support it, even if ministers didn’t initially think so. Through g0v, government websites were examined and rewritten to make them more comprehensible and reachable. “We created a parallel web around which citizens could have a normal conversation. For example, when we did the ministry of education dictionary project, we copied everything from the official website, but turned it into something more accessible.” The thinking is simple, she says: the more clearly information is displayed, the more people will know, and the easier it becomes to have a conversation about what is and isn’t working in a democracy. After g0v came vTaiwan, an online forum allowing people to discuss and petition on issues of public interest. Once there were 5,000 signatures, the petition was taken to the government to be addressed.

Blockchain Could Help Us Reclaim Control of Our Personal Data

Thu, 05 Oct 2017 00:00:00 +0000

Companies such as Experian, Equifax, and TransUnion are able to store huge quantities of our personal data and profit from it in a way that doesn’t always benefit us. And when those same companies lose our personal data and make us susceptible to identity theft, there’s virtually nothing we can do about it. Several organizations are working on returning the value of your data to you, such as the state of Illinois’ pilot to test a blockchain-based birth registry/ID system. Taking this idea one step further, when you are the sole owner of your personal data on purchases, online browsing history, or mobile data, you can also choose whether or not to “sell” your own data, with rights and restrictions using smart ledgers. This could shift the power of (and profit from) data management from big, established firms back to individual users. This would also shift the responsibility. If you lost your cryptographic “keys,” then they would be truly lost and you would have to build your identity again. Equifax and others have shown the weakness of central databases in the hands of a single firm. Mutual distributed ledger systems have the potential to provide us with identity and activity management, even permitting us to make a market selling information about ourselves, taking control and cash back from companies like Equifax. There will certainly be mistakes along the way, but how can we truly object to reclaiming control of our most private property — our personal data?

How AI And Blockchain Are Solving Each Other’s Biggest Challenges

Tue, 29 Oct 2024 00:00:00 +0000

The fusion of artificial intelligence (AI) and blockchain technology has generated excitement, but both fields face fundamental limitations that can’t be ignored. What if these two technologies, each revolutionary in its own right, could solve each other’s greatest weaknesses? Imagine a future where blockchain networks are seamlessly efficient and scalable, thanks to AI’s problem-solving prowess, and where AI applications operate with full transparency and accountability by leveraging blockchain’s immutable record-keeping. This vision is taking shape today through a new wave of decentralized AI projects. Leading the charge, platforms like SingularityNET, Ocean Protocol, and Fetch.ai are showing how a convergence of AI and blockchain could not only solve each other’s biggest challenges but also redefine transparency, user control, and trust in the digital age. While AI’s potential is revolutionary, its centralized nature and opacity create significant concerns. Blockchain’s decentralized, immutable structure can address these issues, offering a pathway for AI to become more ethical, transparent, and accountable. Today, AI models rely on vast amounts of data, often gathered without full user consent. Blockchain introduces a decentralized model, allowing users to retain control over their data while securely sharing it with AI applications. This setup empowers individuals to manage their data’s use and fosters a safer, more ethical digital environment.

Some gut microbes can absorb and help expel ‘forever chemicals’ from the body, research shows

Sun, 13 Jul 2025 00:00:00 +0000

Certain kinds of gut microbes absorb toxic Pfas “forever chemicals” and help expel them from the body via feces, new first-of-its-kind University of Cambridge research shows. The findings are welcome news as the only options that exist for reducing the level of dangerous Pfas compounds from the body are bloodletting and a cholesterol drug that induces unpleasant side effects. The microbes were found to remove up to 75% of some Pfas from the gut of mice. Several of the study’s authors plan to develop probiotic dietary supplements that boost levels of helpful microbes in the human gut, which would likely reduce Pfas levels. “If this could be used in humans to create probiotics that can help remove Pfas from the body then this would be a nicer solution in that it wouldn’t have so many side effects,” said Anna Lindell, Cambridge doctoral student and a co-author of the study. Pfas are a class of about 15,000 compounds most frequently used to make products water-, stain- and grease-resistant. They have been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease and a range of other serious health problems. They are dubbed “forever chemicals” because they do not naturally break down in the environment. The microbes [in the study] largely addressed “long-chain” Pfas, which are larger compounds and more dangerous than smaller “short chains” because they stay in the body longer.

These stories could change how you feel about AI

Sat, 31 May 2025 00:00:00 +0000

Negative or fear-framed coverage of AI in mainstream media tends to outnumber positive framings. The emphasis on the negative in artificial intelligence risks overshadowing what could go right — both in the future as this technology continues to develop and right now. AlphaFold, which was developed by the Google-owned AI company DeepMind, is an AI model that predicts the 3D structures of proteins based solely on their amino acid sequences. That’s important because scientists need to predict the shape of protein to better understand how it might function and how it might be used in products like drugs. By speeding up a basic part of biomedical research, AlphaFold has already managed to meaningfully accelerate drug development in everything from Huntington’s disease to antibiotic resistance. A timely warning about a natural disaster can mean the difference between life and death. That is why Google Flood Hub is so important. An open-access, AI-driven river-flood early warning system, Flood Hub provides seven-day flood forecasts for 700 million people in 100 countries. It works by marrying a global hydrology model that can forecast river levels even in basins that lack physical flood gauges with an inundation model that converts those predicted levels into high-resolution flood maps. This allows villagers to see exactly what roads or fields might end up underwater. Flood Hub ... is one of the clearest examples of how AI can be used for good.
