We are learning just how smart insects can be. As I show in my new book, “The Mind of a Bee,” the latest research indicates that even tiny-brained bees are profoundly intelligent creatures that can memorize not only flowers but also human faces, solve problems by thinking rather than by trial and error, and learn to use tools by observing skilled bees. They even appear to experience basic emotions, or at least something like optimism and pessimism. Bees have a “dance language” by which they can inform others in the hive of the precise location of a rewarding flower patch. The symbolic language involves repeating the motor patterns (“dances”) of a knowledgeable bee on the vertical honeycomb. The movements make reference to gravity and the direction of the sun; since it’s dark in the hive, bees that want to learn from the dancer need to touch its abdomen with their antennae. Sometimes, such dances are displayed at night, when no foraging takes place: The dancer appears to think about locations visited on the previous day, without an obvious need to do so at the time. The observation that bees are most likely sentient beings has important ethical implications. Many species of bees are threatened by pesticides and wide-scale habitat loss, and that this spells trouble because we need these insects to pollinate our crops. But is the utility of bees the only reason they should be protected? I don’t think so. Bees have a rich inner world and unique perception, and, like humans, are able to think, enjoy and suffer.

For the first time in 30 years, legislation has been put forward to address catastrophic wildlife loss in the EU. Legally binding targets for all member states to restore wildlife on land, rivers and the sea were announced today, alongside a crackdown on chemical pesticides. In a boost for UN negotiations on halting and reversing biodiversity loss, targets released by the European Commission include reversing the decline of pollinator populations and restoring 20% of land and sea by 2030, with all ecosystems to be under restoration by 2050. The commission also proposed a target to cut the use of chemical pesticides in half by 2030 and eradicate their use near schools, hospitals and playgrounds. Frans Timmermans, executive vice-president of the commission, said the laws were a step forward in tackling the “looming ecocide” threatening the planet. Around €100bn (£85bn) will be available for spending on biodiversity, including the restoration of ecosystems. The target of 2030 to cut the use of pesticides will give farmers time to find alternatives. The proposals, which campaigners have hailed as a potential milestone for nature, could become law in around a year. Member states would have to create restoration plans to show the commission how they would reach the targets set, and if they fail to follow through they would face legal action. Priority ecosystems include those with the greatest power to remove and store carbon, as well as buffer the impacts of natural disasters.

The artist, writer and technologist James Bridle begins "Ways of Being" with an uncanny discovery: a line of stakes tagged with unfathomable letters and numbers in thick marker pen. The region of [Greece] is rich in oil, we learn, and the company that won the contract to extract it from the foothills of the Pindus mountains is using "cognitive technologies" to "augment ... strategic decision making." The grid of wooden stakes left by "unmarked vans, helicopters and work crews in hi-vis jackets" are the "tooth- and claw-marks of Artificial Intelligence, at the exact point where it meets the earth." "Ways of Being" sets off on a tour of the natural world, arguing that intelligence is something that "arises ... from thinking and working together," and that "everything is intelligent." We hear of elephants, chimpanzees and dolphins who resist and subvert experiments testing their sense of self. We find redwoods communicating through underground networks. In the most extraordinary result of all, in 2014 the Australian biologist Monica Gagliano showed that mimosa plants can remember a sudden fall for a month. Ever since the Industrial Revolution, science and technology have been used to analyze, conquer and control. But "Ways of Being" argues that they can equally be used to explore and augment connection and empathy. The author cites researchers studying migration patterns with military radar and astronomers turning telescopes designed for surveillance on Earth into instruments for investigating the dark energy of the cosmos.

A plump larva the length of a paper clip can survive on the material that makes Styrofoam. The organism, commonly called a “superworm,” could transform the way waste managers dispose of one of the most common components in landfills, researchers said, potentially slowing a mounting garbage crisis that is exacerbating climate change. In a paper released last week in the journal of Microbial Genomics, scientists from the University of Queensland in Brisbane, Australia, showed that the larvae of a darkling beetle, called zophobas morio, can survive solely on polystyrene, commonly called Styrofoam. The findings come amid a flurry of research on ways bacteria and other organisms can consume plastic materials, like Styrofoam and drinking bottles. Now, the researchers will study the enzymes that allow the superworm to digest Styrofoam, as they look to find a way to transform the finding into a commercial product. Industrial adoption offers a tantalizing scenario for waste managers: A natural way to dispose and recycle the Styrofoam trash that accounts for as much as 30 percent of landfill space worldwide. Among plastics, Styrofoam is particularly troublesome. The material is dense and takes up a lot of space, making it expensive to store at waste management facilities, industry experts said. The cups, plates and other materials made from it are also often contaminated with food and drink, making it hard to recycle. Polystyrene fills landfills, where it can often take 500 years to break down.

Beneath our feet is an ecosystem so astonishing that it tests the limits of our imagination. It’s as diverse as a rainforest or a coral reef. We depend on it for 99% of our food, yet we scarcely know it. Soil. Under one square metre of undisturbed ground in the Earth’s mid-latitudes ... there might live several hundred thousand small animals. One gram of this soil – less than a teaspoonful – contains around a kilometre of fungal filaments. But even more arresting than soil’s diversity and abundance is the question of what it actually is. Most people see it as a dull mass of ground-up rock and dead plants. But it turns out to be a biological structure, built by living creatures to secure their survival, like a wasps’ nest or a beaver dam. Microbes make cements out of carbon, with which they stick mineral particles together, creating pores and passages through which water, oxygen and nutrients pass. The tiny clumps they build become the blocks the animals in the soil use to construct bigger labyrinths. Plants release into the soil between 11% and 40% of all the sugars they make through photosynthesis. They don’t leak them accidentally. They deliberately pump them into the ground. These complex chemicals are pumped into the zone immediately surrounding the plant’s roots, which is called the rhizosphere. They are released to create and manage its relationships. The rhizosphere lies outside the plant, but it functions as if it were part of the whole. It could be seen as the plant’s external gut.

MIT researchers have developed a portable desalination unit, weighing less than 10 kilograms, that can remove particles and salts to generate drinking water. The suitcase-sized device, which requires less power to operate than a cell phone charger, can also be driven by a small, portable solar panel, which can be purchased online for around $50. It automatically generates drinking water that exceeds World Health Organization quality standards. The technology is packaged into a user-friendly device that runs with the push of one button. Unlike other portable desalination units that require water to pass through filters, this device utilizes electrical power to remove particles from drinking water. Eliminating the need for replacement filters greatly reduces the long-term maintenance requirements. This could enable the unit to be deployed in remote and severely resource-limited areas, such as communities on small islands or aboard seafaring cargo ships. It could also be used to aid refugees fleeing natural disasters or by soldiers carrying out long-term military operations. “This is really the culmination of a 10-year journey that I and my group have been on. We worked for years on the physics behind individual desalination processes, but pushing all those advances into a box, building a system, and demonstrating it in the ocean, that was a really meaningful and rewarding experience for me,” says senior author Jongyoon Han, a professor of electrical engineering and computer science and of biological engineering.

Tucked away in the mountains of Japan’s Shikoku island, a town of about 1,500 residents is on an ambitious path toward a zero-waste life. In 2003, Kamikatsu became the first municipality in Japan to make a zero-waste declaration. Since then, the town has transformed its open-air burning practices for waste disposal into a system of buying, consuming and discarding with the goal of reaching carbon neutrality. Now, the town estimates it is more than 80 percent of its way toward meeting that goal by 2030. The Zero Waste Center is the town’s recycling facility, where residents can sort their garbage into 45 categories — there are nine ways to sort paper products alone — before they toss the rest into a pile for the incinerators. Residents clean and dry dirty items so they are suitable for recycling. The town offers an incentive system in which people can collect recycling points in exchange for eco-friendly products. There are signs depicting what new items will be made out of those recycled items, and how much money the town is saving by working with recycling companies rather than burning the trash. It’s a way to remind them of their social responsibility. Attached to the Zero Waste Center is a thrift shop where residents can drop off items they don’t want anymore, and others can take them free. All they need to do is weigh the item they take from the shop and log the weight in a ledger so the shop can keep track of the volume of reused items. In January alone, about 985 pounds’ worth of items were rehomed.

Thousands of potentially harmful chemicals could soon be prohibited in Europe under new restrictions, which campaigners have hailed as the strongest yet. The EU’s “restrictions roadmap” published on Monday was conceived as a first step to transforming this picture by using existing laws to outlaw toxic substances linked to cancers, hormonal disruption, reprotoxic disorders, obesity, diabetes and other illnesses. Industry groups say that up to 12,000 substances could ultimately fall within the scope of the new proposal, which would constitute the world’s “largest ever ban of toxic chemicals”, according to the European Environmental Bureau (EEB). Tatiana Santos, the bureau’s chemicals policy manager, said: “EU chemical controls are usually achingly slow but the EU is planning the boldest detox we have ever seen. Petrochemical industry lobbyists are shocked at what is now on the table. It promises to improve the safety of almost all manufactured products and rapidly lower the chemical intensity of our schools, homes and workplaces.” The plan focuses on entire classes of chemical substances for the first time as a rule, including all flame retardants, bisphenols, PVC plastics, toxic chemicals in single-use nappies and PFAS, which are also known as “forever chemicals” because of the time they take to naturally degrade. All of these will be put on a “rolling list” of substances to be considered for restriction by the European Chemicals Agency. The list will be regularly reviewed and updated.

For the past couple of years, I’ve been working with researchers in northern Greece who are farming metal. They are experimenting with a trio of shrubs known to scientists as “hyperaccumulators”: plants which have evolved the capacity to thrive in naturally metal-rich soils that are toxic to most other kinds of life. They do this by drawing the metal out of the ground and storing it in their leaves and stems, where it can be harvested like any other crop. As well as providing a source for rare metals – in this case nickel, although hyperaccumulators have been found for zinc, aluminium, cadmium and many other metals, including gold – these plants actively benefit the earth by remediating the soil, making it suitable for growing other crops, and by sequestering carbon in their roots. Hyperaccumulators are far from being the only non-humans that we might learn from. Physarum polycephalum, a particularly lively slime mould, can solve the “travelling salesman” problem – a test for finding the shortest route between multiple cities – faster and more efficiently than any supercomputer humans have devised. Spiders store information in their webs, using them as a kind of extended cognition: a mind outside the body entirely. A new conception of intelligence is emerging from scientific research: rather than human intelligence being unique or the peak of some graduated curve, there appear to be many different kinds of intelligence with their own strengths, competencies and suitabilities.

In Rambouillet, a small French town around 30 miles (50km) south-west of Paris, a soft blue light emanated from a row of cylindrical tubes. Members of the public ... were invited to bathe in the glow for a few minutes. Soon, the same azure glow will illuminate the nearby, tree-lined Place André Thomé et Jacqueline Thomé-Patenôtre, located just across from the aptly named La Lanterne performance hall, at night. These ethereal experiments are also underway across France. But unlike standard streetlamps, which often emit a harsh glare and need to be hooked up to the electricity grid, these otherworldly lights are powered by living organisms through a process known as bioluminescence. This phenomenon – where chemical reactions inside an organism's body produce light – can be observed in many places in nature. Organisms as diverse as fireflies, fungi and fish have the ability to glow through bioluminescence. The turquoise blue glow bathing the waiting room in Rambouillet ... comes from a marine bacterium gathered off the coast of France called Aliivibrio fischeri. The bacteria are stored inside saltwater-filled tubes, allowing them to circulate in a kind of luminous aquarium. Since the light is generated through internal biochemical processes that are part of the organism's normal metabolism, running it requires almost no energy. "Our goal is to change the way in which cities use light," says Sandra Rey, founder of the French start-up Glowee, which is behind the project in Rambouillet.

Mathematical analysis of the electrical signals fungi seemingly send to one another has identified patterns that bear a striking structural similarity to human speech. Previous research has suggested that fungi conduct electrical impulses through long, underground filamentous structures called hyphae – similar to how nerve cells transmit information in humans. It has even shown that the firing rate of these impulses increases when the hyphae of wood-digesting fungi come into contact with wooden blocks, raising the possibility that fungi use this electrical “language” to share information about food or injury with distant parts of themselves, or with hyphae-connected partners such as trees. Prof Andrew Adamatzky at the University of the West of England’s unconventional computing laboratory in Bristol analysed the patterns of electrical spikes generated by four species of fungi – enoki, split gill, ghost and caterpillar fungi. The research, published in Royal Society Open Science, found that these spikes often clustered into trains of activity, resembling vocabularies of up to 50 words, and that the distribution of these “fungal word lengths” closely matched those of human languages. The most likely reasons for these waves of electrical activity are to maintain the fungi’s integrity – analogous to wolves howling to maintain the integrity of the pack – or to report newly discovered sources of attractants and repellants to other parts of their mycelia, Adamtzky suggested.

The deep-ocean floor is teeming with undiscovered life-forms that help to regulate Earth's climate, a new study finds. Researchers sequenced DNA from deep-sea sediments around the world and found that there is at least three times more life on the seafloor than there is higher up in the ocean. What's more, nearly two-thirds of that life has not been formally identified yet. "It's been known since the 1960s that species diversity is very high in the deep sea, so very high numbers of species," co-author Andrew Gooday [said]. "What was new about this study was that there was a lot of novel diversity at the higher taxonomic level." In other words, there are a lot of unknown evolutionary lineages — like whole families of species — waiting to be discovered. The deep-ocean floor covers more than half of Earth's surface but is home to some of the least-studied ecosystems, according to the study. Previous research analyzed DNA collected through the water column, from above the ocean floor up to the surface, so this latest study sought to complete the picture and give a global view of biodiversity in the ocean by looking at seafloor DNA within deep-sea sediments. The researchers also learned more about the role the deep ocean plays in the so-called biological pump, the process by which ocean organisms such as phytoplankton absorb carbon from the atmosphere near the surface and sink to the deep sea, where the carbon is sequestered in the sediments.

Tropical forests can bounce back with surprising rapidity, a new study published today suggests. An international group of researchers looking at a number of aspects of tropical forests has found that the potential for regrowth is substantial if they are left untouched by humans for about 20 years. For example, soil takes an average of 10 years to recover its previous status, plant community and animal biodiversity take 60 years, and overall biomass takes a total of 120, according to their calculations.” This is due in part to a multidimensional mechanism whereby old forest flora and fauna help a new generation of forest grow – a natural process known as “secondary succession”. These new findings ... suggest that it is not too late to undo the damage that humanity has done through catastrophic climate change over the last few decades. “That’s good news, because the implication is that, 20 years ... that’s a realistic time that I can think of, and that my daughter can think of, and that the policymakers can think of,” said Lourens Poorter ... lead author of the paper. This idea of natural regeneration is frequently disregarded in favour of tree plantations, but according to Poorter, the former yields better results than restoration plantings. “Compared to planting new trees, it performs way better in terms of biodiversity, climate change mitigation and recovering nutrients.” The takeaway message is that we don’t necessarily need to plant more trees when nature is doing it by itself, Poorter said.

Popcorn could soon be used to create sustainable insulation for buildings, replacing the current non-biodegradable materials. Scientists have invented a method to create sustainable building insulation boards using “granulated” popcorn with “excellent” thermal insulation properties and good protection against fire. The plant-based, environmentally friendly material is a sustainable alternative to current building insulation products that are derived from petroleum, said scientists from the University of Göttingen in Germany. About 90 per cent of the materials currently used to make insulation for buildings are made of plastics or mineral fibre, which are non-biodegradable, according to the scientists. These materials generate carbon dioxide during their manufacturing stages and are also rarely recycled when a building is torn down, contributing to pollution and making them unsustainable. Conventional insulating materials made of polystyrene also tend to damage the environment, the scientists pointed out. On the contrary, the researchers said, granulated popcorn is similar to polystyrene and just as lightweight, without having the synthetic material’s downsides. “This new process, based on that of the plastics industry, enables the cost-effective production of insulation boards at an industrial scale,” Alireza Kharazipour, head of the research group from the University of Göttingen, said in a statement.

The U.S. Senate unanimously confirmed Charles "Chuck" Sams III as the next director of the National Park Service on Thursday. He will be the first Native American to lead the agency in its 105-year history. Sams, who is Cayuse and Walla Walla, is a member of the Confederated Tribes of the Umatilla Indian Reservation. The Oregon-based Confederated Tribes is comprised of individuals from the Cayuse, Umatilla and Walla Walla tribes. Sams told the Confederated Tribes' newspaper, the Confederated Umatilla Journal, on Friday that he's "deeply honored" to serve as the 19th director of NPS. "I am also very deeply appreciative of the support, guidance and counsel of my Tribal elders and friends throughout my professional career," Sams told the newspaper. "I look forward to carrying on the responsibility of being a good steward of our natural resources and in joining the dedicated and dynamic staff of the National Park Service." Sams' confirmation marks the first time in nearly five years that the department will have an official director. The position has been filled with various people serving as acting heads since January 2017. Sams has worked in state and tribal governments, as well as in natural resource and conservation management, for more than 25 years. In a press release on Friday, tribal leaders commended the confirmation, with Confederated Tribes trustee member Kat Brigham saying that Sams "knows the outdoors." "He understands the importance of helping families develop a relationship with the land," Brigham said.

Huge amounts of plastic ends up rivers and oceans every year, harming the environment and potentially also human health. But what if we could pull it out of water with the power of magnets? [Chemistry student] Ferreira became determined to find a solution to remove microplastics from water. He started by designing his own spectrometer, a scientific instrument that uses ultraviolet light to measure the density of microplastics in solutions. "I could see there were a lot of microplastics in the water and they weren't just coming from big plastic breaking down in the sea," he says. It was on his local beach that Ferreira came up with a solution that could extract microplastics from water. "I found some oil spill residue with loads of plastic attached to it," he says. "I realised that oil could be used to attract plastic." Ferreira mixed vegetable oil with iron oxide powder to create a magnetic liquid, also known as ferrofluid. He then blended in microplastics from a wide range of everyday items, including plastic bottles, paint and car tyres, and water from the washing machine. After the microplastics attached themselves to the ferrofluid, Ferreira used a magnet to remove the solution and leave behind only water. Following 5,000 tests, Ferreira's method was 87% effective at extracting microplastics from water. Ferreira is currently in the process of designing a device which uses the magnetic extraction method to capture microplastics as water flows past it. The device will be small enough to fit inside waterpipes to continuously extract plastic fragments.
Note: Researchers from Australia are also finding innovative ways to rapidly remove hazardous microplastics from water using magnets. Explore a treasure trove of concise summaries of incredibly inspiring news articles which will inspire you to make a difference.
The world’s first customer delivery of “green steel” produced without using coal is taking place in Sweden, according to its manufacturer. The Swedish venture Hybrit said it was delivering the steel to truck-maker Volvo AB as a trial run before full commercial production in 2026. Volvo has said it will start production in 2021 of prototype vehicles and components from the green steel. Steel production using coal accounts for around 8% of global greenhouse gas emissions. Hybrit started test operations at its pilot plant for green steel in Lulea, northern Sweden, a year ago. It aims to replace coking coal, traditionally needed for ore-based steel making, with renewable electricity and hydrogen. Hydrogen is a key part of the EU’s plan to reach net zero greenhouse gas emissions by 2050. Hybrit is owned by the steelmaker SSAB, state-owned utility Vattenfall and miner LKAB. SSAB accounts for 10% of Sweden’s and 7% of Finland’s carbon dioxide emissions. It said the trial delivery was an “important step towards a completely fossil-free value chain. The goal is to deliver fossil-free steel to the market and demonstrate the technology on an industrial scale as early as 2026.” Another green steel venture, H2 Green Steel, is planning to build a fossil fuel-free steel plant in the north of Sweden, including a sustainable hydrogen facility, with production starting in 2024.

Across the world, about 80 percent of wastewater is dumped back into the ecosystem without being treated. Untreated wastewater leads to a range of problems and contributes to faecal contamination of drinking water sources for about 1.8 billion people. Treating wastewater requires treatment plants that can be expensive. Now, a Bengaluru-based startup ECOSTP Technologies has developed a new and efficient design for sewage treatment plants that takes inspiration from the digestive system of cows. It is so efficient that it does not even need the power to run. Cows have a powerful digestive system made up of four chambers containing bacteria that do not need oxygen. As grass passes through these chambers, the bacteria break it down into smaller parts eventually converting it to gas, nutrients, water, and waste. [Bengaluru-resident Tharun] Kumar and his team developed a treatment plant to mimic this structure and used the bacteria from cow dung to break down the waste in wastewater. Their plants do not even require power. Instead, they use gravity to move wastewater across chambers. In the treatment plant, the further wastewater travels, the cleaner it gets. Eventually, the solid waste settles down, and the wastewater is converted into gas and clear water, which can be safely reused. “Since inception, we have saved 280 million litres of water and have saved 315 MW of power which is equivalent to powering 35 villages for a year,” Kumar, co-founder, and CEO of ECOSTP Technologies [said].

The list of mycologists whose names are known beyond their fungal field is short, and at its apex is Paul Stamets. In a new “astromycological” venture launched in conjunction with NASA, Stamets and various research teams are studying how fungi can be leveraged to build extraterrestrial habitats and perhaps someday even terraform planets. [Stamets:] Fungi were the first organisms that came to land, munching rocks, and fungi gave birth to animals about 650 million years ago. We’re descendants of the descendants of these fungal networks. [Plants that support terraforming] need minerals, and pairing fungi up with the plants and debris from humans [causes them to] decompose into a form that then creates rich soils that could help generate the foods that astronauts need. We grow lots of reishi mycelium. We grow reishi blocks. We wanted to crush these blocks in order to turn them into soil. This great engineer built us a hydraulic stainless steel press, and I had like 2,000 psi [pounds per square inch] in this press, and we gave it my reishi blocks, and it bent the stainless steel. Trying to compress it, it actually broke the machine. This thing will crush rocks all day long and could not crush mycelium. They’re also good at retaining heat, so their insulation properties are phenomenal. Moreover, these could become batteries. You can have solar panels on a structure on Mars made of mycelium. (The entire mycelium is about 85 percent carbon, and studies have shown that porous carbon can be an excellent capacitor.) You could then pregrow these and arrange them on a form such that they become nanobatteries. And they could then not only insulate you from the cold on the Martian or asteroid surface, but the house itself becomes a giant battery for power because they’re so rich in carbon fibers.

Outside of a library in Cambridge, Massachusetts, an over-80-year-old copper beech tree is making music. As the tree photosynthesizes and absorbs and evaporates water, a solar-powered sensor attached to a leaf measures the micro voltage of all that invisible activity. Sound designer and musician Skooby Laposky assigned a key and note range to those changes in this electric activity, turning the tree’s everyday biological processes into an ethereal song. That music is available on Hidden Life Radio, an art project by Laposky. Hidden Life Radio also features the musical sounds of two other Cambridge trees: a honey locust and a red oak. After he read the book The Hidden Life of Trees ... Laposky thought to tune into the music trees could be making. The name Hidden Life Radio was inspired by that book, written by German forester Peter Wohlleben, which details the social networks and “sentient” capabilities of trees. “Most people probably love trees and [still] don’t consider them all the time,” Laposky says, noting a condition called “plant blindness,” in which people fail to notice the flora in their own environment. “In cities, the trees are there, but unless they’re providing shade or you’re picking apples from them, I feel like people don’t necessarily consider trees and their importance.” Tree canopies are crucial to cities, providing shade that can lower summer temperatures significantly, reducing air pollution, sequestering carbon, and providing a mental health benefit.
