This line of research into how insects hear sounds using specialized, microscopic hairs could inspire a new generation of acoustic tools. Standard microphones are devices that contain membranes within them that can detect sound pressure levels. By mimicking these biological systems, such as using structures like these hairs in place of membranes, future microphones could be designed to instead measure the air particle velocity caused by sound, alongside the sound pressure levels.

A good list of recent neuroscience books released, not really reviews but still a great starting point if you want to read about current neuroscience topics of research.

On 10 January 1992, during a storm, a container full of bath toys fell off a ship travelling across the Pacific ocean. The container opened and the 28,000 toys, including yellow rubber ducks, were released.

...

We’ll model the ducks as ‘tracer particles’ in the ocean. The term ‘tracer particles’ refers to small objects that move with a fluid without really changing how it behaves. They are very common: examples include leaves on the surface of a river and, fortunately, rubber ducks in the ocean. Our simulations will try to track the amount of these particles in different parts of the ocean.

Hello person. This is Anton and in this video we're going to discuss some of the recent studies that sort of rewrite the idea behind the origin of life and specifically the story of how you, me and basically every living cell on the planet actually got here. And well that's because for decades we've had this somewhat beautiful and almost a romantic idea of a primordial soup serving as the origin of all life. We imagined a warm little pond billions of years ago, possibly zapped by lightning in order to create some kind of a single perfect cell that spontaneously snapped into existence and eventually split into the entire tree of life.

But according to at least two recent papers from August and June of 2026, that story seems to be kind of incomplete and possibly incorrect. and specifically because we now have a lot of new evidence in regards to something referred to as LUCA, the Last Universal Common Ancestor. With this new evidence suggesting that LUCA was not fully alive and it was more like some kind of a biological cyborg of chemistry and geology, physically stuck inside deep sea rocks and running its metabolism using raw metals as its engines. In other words, it was not truly alive and did not represent a living cell, which actually leads us to the next mind-blowing proposition.

The two main branches of life, the bacteria and the archa did not just split off from LUCA, but instead represented a completely separate evolution from this cyborg and evolved completely independently, possibly in two separate locations, which in a very real sense implies that cellular life potentially started not once but twice on our planet, which if confirmed would be revolutionary. And so in this video, we're going to discuss some of these recent discoveries, connect them to a few other ideas, including the ideas behind how Jupiter potentially played a role in a lot of this and howeven our baby sun influenced certain things as well. And though we're not going to be solving this biological paradox just yet, we are going to come just a little bit closer to answering the question of the origin of life. And so I guess let's start with this most recent bombshell published in August that as always you can find in the description below. [...]

Some researchers have placed their bets on natural quantum systems such as atoms. To use a single atom as a qubit, you must first isolate and trap it in a vacuum chamber, and researchers have pursued two distinct approaches to doing so. In trapped-ion quantum computing, researchers knock one electron off each atom to get positively charged ions that can be held in place by electric fields. The other approach uses arrays of tightly focused laser beams, called optical tweezers, to trap neutral atoms.

Other researchers are pursuing an alternative approach, called superconducting quantum computing, which involves the design of artificial qubits. Using modified versions of microfabrication processes developed for classical computing, researchers assemble tiny circuits made of metals like aluminum and niobium that become superconductors when cooled to very low temperatures. Housed in special cryogenic systems called dilution refrigerators, these superconducting circuits can act like qubits. Many other qubit candidates have been explored, from electron spins to photons to more exotic quantum systems.

Some really cool photos in this article, Quantum Computers are not bullshit even though hilariously almost everything about them seems like complete bullshit... which isn't to say we will see practical Quantum Computers proliferating any time soon but they aren't a vaporware technology the way AI is for example.

The difference is that large amounts of simultaneous calculations can be done with Quantum Computers in a way you can't tackle fundamentally with Classical Computers. The waves help you find many complex answers much faster at the cost of some degree of confidence that is acceptable for certain applications and when accounted for in architecture.

The team used alginate to make materials they call soft dendritic colloids (SDCs). These are particles with hierarchical branches that give them a fuzzy appearance under a microscope and, much like gecko feet, create a large surface area that boosts van der Waals forces and makes the material really sticky. Velev says a single SDC particle can capture more than a thousand polymer particles from a suspension (Adv. Funct. Mater. 2025, DOI: 10.1002/adfm.202423494).

Could the precise architectural form of your residence influence how much you participate in politics? A new study by MIT scholars finds this to be exactly the case—at least in Accra, Ghana, where many people live in semi-communal structures known as "compound houses," often sharing kitchens, bathrooms and common living-room spaces, while having private bedrooms.

The detailed study of homes in Ghana's capital finds that residents of compound houses are more likely to vote, attend rallies and take part in political campaigns, compared with people with more private forms of housing.

"The overarching pattern we find is that if you compare people who live in compound houses to residents of other housing types, like single-family homes or self-contained apartments, there is a pretty big difference in political actions," says Noah Nathan, an MIT political scientist and co-author of a newly published paper detailing the study's results. "People seem to vote more, and there are more other types of political behavior, like going to rallies, participating in campaigns and contacting politicians."

While those differences could stem from factors other than housing, the highly granular study suggests the architecture itself really matters. The researchers examined the specific floor plans of compound houses and found variations in people's political information and social connections—key factors that existing studies show predict political activity—that map to differences in where people live within compound houses.

"We show that those kinds of social relationships and exchanges of political information seem to vary systematically with people's individual locations within the layouts of the buildings they live in," says Nathan, an associate professor in MIT's Department of Political Science. "That's consistent with architectural design leading you to have different levels of political participation."

The open-access paper, "Vernacular Architecture and Grassroots Urban Politics: How Politics Is Embedded in Residential Design," is published in the American Political Science Review. Nathan's co-author is Paige Bollen, Ph.D. '23, an assistant professor of political science at Ohio State University.

Over the past 70 years, the study of epigenetics has evolved from a research curiosity for outsiders to one of the most hyped biological concepts. While the pioneers of epigenetic research were met with disbelief when they described phenomena that did not follow the normal Mendelian laws of inheritance, the popular media today praises the modulation of epigenetics through behavioral changes as a cure for diseases. The concept that environmental influences can cause stable, heritable changes in gene expression has been embraced with such enthusiasm that the study of epigenetics has found its place in virtually every medical biology field. Because of the somewhat inflationary way in which the word epigenetics is used nowadays, it is all the more important to clarify definitions and terms before talking about epigenetic studies.

Climate change is widely understood as an environmental and economic threat, but new research from the University of Sydney shows it is also a growing social crisis, weakening the relationships people rely on to survive.

Published in Nature Human Behaviour, the international study found climate change is eroding social connection at a time when those ties are most needed, creating a feedback loop where disruption to relationships reduces people's ability to adapt and recover.

"Climate change isn't just something happening 'out there,'" said lead author Dr. Marlee Bower from the Matilda Center for Research in Mental Health and Substance Use. "It's reshaping how we live, how we connect, and ultimately who has support when things go wrong."

US proposes endangered species protections for an imperiled Jamaican butterfly

• The U.S. has proposed listing a rare butterfly from Jamaica, the Jamaican kite swallowtail under the Endangered Species Act.
• The striking blue-green and black butterfly, endemic to this island country, hovers on the brink of extinction. Scientists have observed no more than 250 adults in the wild in recent years.
• Deforestation, devastating hurricanes and droughts on the island have destroyed much of this butterfly’s breeding sites; only four remain. Demand for framed butterflies used in home decor is another factor in their disappearance.
• ESA listing would bring attention to the species and stop its trade in the U.S. Conservationists hope it will also fund efforts to protect the butterfly’s habitat.

The U.S. Fish and Wildlife Service (USFWS) recently proposed listing Jamaica’s most imperiled butterfly, the Jamaican kite swallowtail, as endangered under the Endangered Species Act (ESA).

The species (Protographium marcellinus), a small, fast-flying butterfly, flutters through its limestone forest home. Its wings, painted in streaks of bright turquoise and black with a dash of red, sport long, narrow tails.

These charismatic butterflies live on this island and nowhere else. In recent years, they’ve nearly disappeared. Back in the 1960s, scientists recorded about 750,000 individuals; that number has plummeted to between 50 and 250 today. In some years, they’ve seen none.

It’s such an alarming decline that scientists say this swallowtail should jump two categories on the IUCN Red List, from vulnerable to critically endangered.

“This listing would be a real turning point for this species,” said Dianne DuBois, senior scientist at the U.S.-based NGO Center for Biological Diversity, which has been fighting for ESA protections for the butterfly since 1994. After a few failed attempts, it sued USFWS in 2021, which resulted in the agency drawing up the current proposal.

ESA listings prevent extinction in 99% of the species under the act, but the wait is often quite long, about 12 years on average. Time may not be on its side for the Jamaican kite swallowtail, which hangs on the brink of extinction.

“We wish this proposal had come three decades ago,” DuBois said. “We really want to urge the Fish and Wildlife Service to work quickly to finalize these protections and let the ESA work its magic.”

Vaughan Turland at Jamaica’s Windsor Research Centre, who has studied the species for decades, welcomed the U.S. proposal. “Any formal recognition of the potential demise of such an iconic species is important,” he said, because it raises awareness and urges urgent conservation actions.

Hammered by vanishing habitat, climate change and trade

Jamaica is rapidly losing its forests, and along with it, the Jamaican kite swallowtail is losing its homelands. Trees are felled to make way for mines, quarries, expanding farmlands, human settlements and livestock grazing.

Baby caterpillars feed only on the leaves of the black lancewood trees (Oxandra lanceolata) found in limestone forests. Cocooned pupae stay buried in the leaf litter for months before turning into showy butterflies. Meanwhile, black lancewood is targeted by loggers: Thousands of these trees are cut down to make furniture, fish pots, stakes for growing yams and charcoal for cooking, among other things.

As a result, the butterfly’s breeding habitat has shrunk by about 70% since the 1960s, according to a study by Turland and his colleague Thomas Turner from the Florida Museum of Natural History, who’s also considered an authority on the species. Today, the swallowtails breed in just four sites on the island where a few dense stands of black lancewood remain.

Extreme weather events, including hurricanes and drought, pose an increasing threat. Hurricane Melissa, one of the strongest hurricanes on record in the Atlantic basin, made landfall in Jamaica in October 2025, damaging one of the butterfly’s few remaining breeding sites, Turland said.

Because of its striking appearance, the rare butterfly is also in demand for home décor, framed and hung on the wall. It’s part of a massive trade that includes more than 3,700 butterfly species the world over, mostly coming from the Global South. They’re bought primarily by consumers in the U.S. and Europe.

Fewer than 70 butterfly species have trade protections under CITES, the global wildlife trade agreement. All others, including the Jamaican kite swallowtail, can be traded internationally without restrictions.

“The Jamaican kite swallowtails are one of many butterfly and invertebrate species that have kind of caught the eye of collectors that pin and frame them for display,” DuBois said.

How many are captured and sold remains unclear, as it’s illegal to catch them in Jamaica, but it’s likely a lucrative activity in a country where workers average $34 a day. Dubois said this butterfly sells online for as much as $178 apiece.

For an animal this rare, every sale matters. “Even low levels of collection can be devastating for a species with such a small population,” DuBois said.

This is where the ESA listing could make the most impact. If finalized, the listing would “ensure that this species no longer gets caught up in this popular online decor trade,” DuBois said. It could also bring more attention to the butterfly’s perilous state, and with it, funding to protect its habitat, she added.

The ESA listing proposal is currently open for comments until June 16, and it’s an open forum: Anyone with information about the species or who is interested in butterfly conservation can post statements. USFWS will then have a year to make its decision. If the listing is finalized, it would be the first addition to the ESA since U.S. President Donald Trump took office for his second term.

“If we can get it listed, there’s a very good chance that it will avoid extinction,” DuBois said.

Climate change could erase most South American cloud forests, study warns

• Climate change could eliminate up to 91% of South America’s cloud forests by 2070 under a high-emissions scenario; even the most optimistic projections show significant losses.
• Because cloud forests capture moisture from fog and release it into streams, their disappearance threatens the drinking water supply of an estimated 16 million people who live downstream.
• Only about one-third of South America’s cloud forests fall within protected areas, and those protections cannot shield the forests if the climate itself becomes too warm and dry to support them.
• Scientists say cutting greenhouse gas emissions is the most essential step, alongside stronger protections and financial incentives for landowners to conserve and restore forests in areas projected to remain climatically suitable.

Up in the misty mountains, teems a kaleidoscope of life: trees drip with epiphytes, hummingbirds sip from bright blossoms, and rare creatures occupy every nook in the cloud forests, which scientists have likened to terrestrial coral reefs. But a new study warns that climate change could strip away the conditions that make cloud forests possible, and in the worst case, erase nearly all of them within 50 years.

The research, published in the Journal for Nature Conservation, used machine learning and modeling to project how cloud forest distribution in South America could shift under two different climate scenarios by 2070.

The study reports that under a high-emissions pathway, up to 91% of cloud forest area could be lost. Even under the most optimistic scenario, researchers calculate a 12% reduction, roughly 21,000 square kilometers (8,100 square miles), an area the size of El Salvador.

Cloud forests occupy a narrow band of land, typically between 1,000 and 3,000 meters (about 3,300-10,000 feet) above sea level, and are defined by persistent fog, cool temperatures and high humidity. That humidity shapes everything, from the mosses and orchids draped across surfaces, to the birds and amphibians found nowhere else on Earth.

The study notes these ecosystems harbor some 1,946 restricted-range species, representing roughly 8% of the world’s mammals, birds, amphibians and tree ferns. Among the species endemic to South American cloud forests are the flamboyant Andean cock-of-the-rock (Rupicola peruvianus), whose brilliant orange-plumed males perform elaborate courtship dances on the forest floor; the critically endangered yellow-tailed woolly monkey (Lagothrix flavicauda), Peru’s largest endemic primate; and countless glass frogs — delicate, translucent amphibians whose eggs can be seen developing through their own skin.

As temperatures rise, the base of clouds climbs higher up the mountain slopes, effectively shrinking the zone where cloud forests can exist. Species are pushed upward into increasingly fragmented habitat. For those species that live only near the summits, there is nowhere left to go.

But the stakes go beyond biodiversity. Because cloud forests capture fog on their leaves and branches and release it steadily into surrounding watersheds, communities downstream depend on them for reliable drinking water, particularly during dry seasons when other sources run low.

The researchers estimated that about 19.5 million people live within 5 kilometers (3 miles) of rivers whose flow is influenced by upstream cloud forests. Study lead author Patrícia Vieira Pompeu, a professor at the State University of Mato Grosso do Sul in Brazil, warned that under the high-emissions scenario, that supply would be compromised for an estimated 16 million people, or 83% of current beneficiaries.

“Cloud forests play an important role in regulating water in the headwaters of many Amazonian rivers, especially those originating in the Andes and other elevated regions of northern Amazonia,” Pompeu told Mongabay. “Their loss could reduce dry-season water availability and increase hydrological variability in Andean–Amazonian tributaries, potentially affecting downstream ecosystems and human populations.”

The study also found that only about one-third of South America’s cloud forests currently fall within protected areas. But that protection offers no guarantee of survival if the climate itself becomes unsuitable. Under the high-emissions scenario, the remaining protected patches would shrink dramatically in size, potentially becoming too small and isolated to support viable populations of many species.

“Cloud forests are already known to face many threats from human land-use change,” Walter Jetz, a biodiversity scientist at Yale University in the U.S., who wasn’t involved in the study, told Mongabay. “Montane cloud forests exist in a slim and globally rare climate space marked by cold and foggy conditions. There is no doubt that changing climate, combined with their narrow distribution and encroachment, makes montane cloud forests some of the most vulnerable highly biodiverse ecosystems on the planet.”

The study’s authors argue that two strategies are especially critical for the survival of cloud forests: stronger implementation of payments for ecosystem services, which provide financial incentives for landholders to conserve or restore forests upstream of populated watersheds; and better management of existing protected areas. Identifying which cloud forest patches are likely to remain climatically suitable even under future scenarios, they argue, should guide where those resources are focused.

But Pompeu said the most fundamental solution remains the same as for every climate-driven ecological crisis. “The key message is that we need to care about CO2 emissions,” she said. “We need to stop, or we will have problems with everything.”
