Undergraduate Chris Zuo sent me the note "Four minutes is too long" along with photos of countless mosquito bites on his bare skin. This full-body massacre wasn't the result of a camping trip gone awry. He'd spent that limited amount of time in a room with 100 hungry mosquitoes while wearing nothing but a mesh suit we thought would have protected him. [...]
Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck Institute for Extraterrestrial Physics and Giulia Roccetti at the European Space Agency, a new study predicts that hydrogen could act as a potent greenhouse gas—potentially providing habitable conditions for billions of years after their host planets are first ejected from their stellar systems. The work has been published in Monthly Notices of the Royal Astronomical Society. [...]
What would happen if AI becomes capable of performing essentially all economically valuable work? In a wide-ranging Q&A, Yale economist Pascual Restrepo dives into how economists view the future of labor markets. [...]
A critically endangered monkey has given birth just months after pioneering surgery saved her from undergoing an amputation. Masaya, a 15-year-old roloway monkey at Chester Zoo, had a golf-ball-sized mass removed from her foot last summer in a complex operation carried out jointly by zoo vets and surgeons from the University of Liverpool's Small Animal Teaching Hospital. [...]
If you've ever ordered food through DoorDash, Uber Eats or Instacart, you may have realized the person who delivers it isn't a salaried employee. They're gig workers—independent contractors who pick up delivery tasks through an app, get paid per delivery and have no guaranteed hours, benefits or minimum wage protections. [...]
This week, among a lot of other important findings, we learned that emperor cichlid fish have gaze sensitivity and dislike it if you look at them—or especially their children. England is looking for a solution to its 5-billion-liter water deficit. And a high-fiber diet isn't only healthy for you—it also benefits your parasitic tapeworms! [...]
A lactic acid bacterium isolated from kimchi may help promote the removal of nanoplastics from the body by binding to them in the intestine. Nanoplastics are ultrafine plastic particles measuring less than 1 micrometer that are generated during the degradation of larger plastic materials. These particles can enter the human body through food and drinking water. Due to their extremely small size, nanoplastics may cross the intestinal barrier and accumulate in organs such as the kidneys and brain. However, biological strategies to reduce nanoplastic accumulation in the gastrointestinal tract remain at an early stage of research. [...]
Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent phases of matter. In a study published in Nature Physics, Qimiao Si's group at Rice University, in collaboration with researchers at the Weizmann Institute of Science, identified compact molecular orbitals that act as the key electronic agents governing the exotic behavior of these materials. [...]
Youth in foster care often experience family instability, which can disrupt the continuity of their relationships and social connections. Therefore, the strength and stability of their social support networks can play a critical role in shaping their lives. [...]
Alaska's glaciers respond to climate change by melting for three additional weeks with every 1 degree Celsius increase in the average summer temperature, data from satellite-mounted radars show. [...]
A burst of unusual March heat is hitting the United States this week and into next, busting previous monthly heat records by wide margins. While heat is most acutely felt by people exposed to it, graphics and charts convey the scale of this extreme event. Temperatures in the West remain far above what's typical for March, a sign the early season heat is not letting up. Compared with the average highs for March between 1991 and 2020, temperatures across some parts of Oklahoma, Nebraska, northern Texas and South Dakota are reaching at least 20 degrees Fahrenheit (11 degrees Celsius) above normal. [...]
New research led by James Cook University (JCU) emphasizes that the success of marine protected areas (MPAs) depends largely on understanding and influencing people's behaviors within their borders. The study demonstrates that effective conservation relies on compliance—a critically underappreciated issue that needs to be systematically and adaptively addressed. [...]
Animals do all sorts of things to attract each other as potential mates. Many birds, for example, produce feathers with elaborate color patterns—from the iridescent plumage of many hummingbirds to the famously brilliant tail of a peacock. Charles Darwin, an early pioneer in the theory of evolution, saw these colors and concluded that they exist because other birds find them attractive. [...]
Across the sciences, researchers are asking why so many scientists leave their fields. A new study from Virginia Tech suggests at least part of the answer may be surprisingly simple. Scientists who feel a stronger sense of belonging in their discipline are more likely to intend to stay. Those who feel they do not belong are more likely to consider leaving. Published recently in Biological Conservation, the study examined ornithologists, people who study birds, and found a clear link between belonging and intentions. [...]
Most of Europe's original natural forests have been transformed for agriculture and managed forests producing energy, paper, and timber. The few remaining "old-growth" natural forests are relics of the past that illustrate how forests would have looked in the absence of human management. They can, therefore, tell us how people have transformed forests. [...]
New research from the University of East Anglia (UEA) reveals that King Harold's legendary 200-mile march to the Battle of Hastings in 1066 never happened. Instead, the journey was made largely by sea. The findings overturn one of the most iconic stories in English history, altering how the Norman Conquest is understood in classrooms, museums, and public memory. [...]
Two University of Victoria (UVic) geologists have integrated field geology with statistical modeling to give scientists a new view of the chemical reactions happening on ocean floors billions of years ago. The revised picture shows that big changes in the carbon cycle were happening earlier than expected, and at the same time as ballooning atmospheric oxygen and global glaciation. [...]
The building blocks of proteins, amino acids, are essential for all living things. Twenty different amino acids build the thousands of proteins that carry out biological tasks. While some are made naturally in our bodies, others are absorbed through the food we eat. [...]
For more than a century, condensed matter physics has grappled with one of its greatest unsolved challenges: how to build superconductors that operate at room temperature and transmit electricity with no loss. Now, in a paper published in Nature, a team of Harvard physicists has reported new insights into why one promising superconductor has yielded mysteriously uneven results. [...]
Chosen families are evolving but remain a cherished—and vital—lifeline for many. Mention "communal living" and the image that may spring to mind is the free-love, back-to-the-earth hippy communes of the 1960s, complete with bandannas and fringed suede vests. But communal living is once again very much part of the zeitgeist—albeit with a very different look. [...]
The high-performance semiconductor devices powering smartphone displays, AI computing, EV batteries and more are increasingly incorporating 2D materials to overcome silicon's scaling limits. To optimize these technologies, a University of Michigan Engineering team developed a precise mathematical framework that accounts for anisotropic—or unevenly spreading—conductivity and device geometry. [...]
When most people think about corals, they imagine a tropical reef with crystal blue water, teeming with colorful fish. But, in the depths of the cold, murky Gulf of Maine, deep-sea corals thrive, feasting on a steady supply of organic matter raining down from the surface ocean. [...]
For half the world's population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet's aquifers, or groundwater basins, are dropping. Declining water tables leave entire regions vulnerable to drought, land subsidence or seawater intrusion while damaging ecosystems and reducing water access. Properly securing this resource is a matter of social, humanitarian and environmental security. [...]
A new Murdoch University study has found that cold-blooded animals (ectotherms) are unable to adjust physiologically to daily temperature fluctuations, a limitation that could leave them increasingly vulnerable as climate change drives even greater temperature variability. Daily temperature variations are a common feature in natural environments, ranging from subtle to extreme depending on the geographic location, season, and local climate patterns. [...]
Climate warming can increase plant growth in permafrost regions by lengthening the growing season, speeding up plant metabolic processes, and allowing deeper root penetration as permafrost thaws. However, the capacity for additional vegetation to offset the carbon released during permafrost thawing depends on nitrogen supply. [...]
Researchers at The Hong Kong University of Science and Technology (HKUST) have developed CarGAP, a chemo-optogenetic tool that uses vitamin B₁₂ and green light to precisely control gap junctions, the microscopic channels enabling direct cell-to-cell communication. This innovation allows on-demand closing and opening of these intercellular bridges, providing unprecedented spatiotemporal control over vital molecules and electrical signals. Demonstrated in both mammalian cells and living fruit flies, CarGAP provides a powerful new way to study development, immunity, and neural activity, with far-reaching potential for understanding disease mechanisms and advancing regenerative medicine. [...]
Two deep-sea amphipod species have been found to live in both hemispheres and share features, according to a new study that boosts our understanding of the biodiversity and evolutionary processes shaping deep-sea ecosystems. Dr. Paige Maroni and Professor Alan Jamieson, from The University of Western Australia's School of Biological Sciences, were co-authors of the study published in Marine Biology. [...]
While parts of New York and New Jersey were "building back better" after Superstorm Sandy, residents of flood-prone public housing in Rockaway, Queens, were left without heat or running water for years. [...]
Nudibranchs are often referred to as the butterflies of the sea. Nudibranchs live worldwide, primarily in warm, shallow marine regions, and stand out for their flamboyant colors and diverse shapes. A team from the Max Planck Institute of Colloids and Interfaces in Potsdam and the University of Cambridge has now discovered how they create their colorful patterns. According to their findings, published in the Proceedings of the National Academy of Sciences, the color is produced by nanostructures, each of which creates a specific color impression. [...]
Glittery sea worms and sea squirts fit for "The Lord of the Rings" universe might sound like pure fantasy, but they're very real creatures living in the deep sea. Some of these otherworldly ocean animals are even featured in the latest "Top 10 New Marine Species" list published by the World Register of Marine Species (WoRMS). [...]
