An irreversible shift in the chemical makeup of the Arctic Ocean driven by climate change is disrupting the region's food chain, a study suggests. Widespread loss of Arctic sea ice has led to a sharp fall in levels of a key nutrient, affecting populations of plankton, fish,

Massive amounts of dust swirl around active nuclei at the centres of galaxies, and these discs could give rise to vast numbers of rocky planets, some even the size of stars
New research reveals that plants have the ability to detect their neighbors' growth rates through aromatic cues called volatile organic compounds (VOCs) and subsequently adjust how much energy they invest into their own growth or defense strategies through responsive gene
Urban planning needs to tackle greenhouse gas emissions—and an important way to achieve this is by reducing the number and length of car commutes. This can be achieved primarily by ensuring that homes are located close to city centers and workplaces, so well-targeted building
A newly identified protein called GPNMB may play a major role in helping Parkinson’s disease spread through the brain. Researchers discovered that immune cells release the protein in response to damaged neurons, creating a vicious cycle that speeds up brain cell degeneration.
A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 infection. Instead, the most severe long COVID symptoms were associated with increased brain activity in regions involved in mood and
A surprising new approach to depression treatment is showing early promise — not by targeting brain chemicals, but by calming the immune system. In a small clinical trial, researchers found that an anti-inflammatory drug normally used for rheumatoid arthritis appeared to ease
When the body runs low on protein, the gut sends powerful signals to the brain that reshape cravings and push animals to seek essential amino acids instead of sugar. Researchers say this newly discovered gut-brain network could transform our understanding of appetite,
Our sun is a loner. It lacks a stellar companion hurtling through interstellar space with it. But we've known for a long time that that's actually relatively rare—most stars have at least one gravitationally bound partner. Understanding how exactly those stars are related to
Internal changes due to the sun's "active biorhythm" have become increasingly "skin-deep" over the past four solar activity cycles, according to a new study.
A decade ago, Bradley Markle, an assistant professor at the Institute of Arctic and Alpine Research at the University of Colorado Boulder, noticed an odd pattern while sifting through temperature records from the end of the last ice age in Antarctica. The records seemed to defy
Johanna Harvey, an assistant professor of wildlife disease ecology at the University of Rhode Island, has described bird flu in public presentations as a quiet virus with loud consequences. Now, she's published a new paper in Wildlife Monographs, describing how circulating
Persistent methane emissions from sectors such as agriculture and growing debates over the credibility of carbon offsets are creating new challenges for governments and companies pursuing net-zero commitments. New research suggests that temporary carbon storage may have a
When a team of researchers recorded a low thundering underneath the surface of the Hudson River, they thought they were hearing the muffled rumble of trains. A closer look and listen led to a much more interesting discovery: The thunder came from Atlantic sturgeon—an iconic and
The old "monkey see, monkey do" adage may rest on some neuroscientific evidence, finds a new Yale study. To examine how the primate brain facilitates cooperative behavior among individuals during social interaction, a team of researchers trained pairs of marmoset monkeys to
Scientists at William & Mary's Batten School & VIMS, FlowWest and the University of Maryland Center for Environmental Science recently announced that the Chesapeake Bay's annual "dead zone" is expected to be relatively mild this summer.
Researchers at Cornell University have developed a safer and more precise way to study how genes function in living tissues by refining a recently developed CRISPR-based genetic technique in fruit flies, enabling researchers to better study how genes contribute to development
Researchers at TU/e have demonstrated that energy transfer without loss via light or heat can occur over much greater distances than previously thought possible thanks to vibrations in microscopic gold rods. They succeeded in making energy jump from one particle to another over
Centuries before we started debating the transformative effect of AI on science, a new light in the sky shone the way The post The Supernova That Sparked the Original Scientific Revolution appeared first on Nautilus .
Heat behaves in predictable ways: a hot cup of coffee cools, a laptop warms your hands, the sun heats Earth. But at scales thousands of times smaller than a human hair, those rules begin to break down, and scientists are learning how to take advantage of that.
Astrophysicists think that black hole masses are hierarchical. The largest are supermassive black holes (SMBH) like the one at the center of the Milky Way and other galaxies. Stellar mass black holes are born of collapsing stars, and are smaller. The smallest of all are the
People are exposed to thousands of chemicals every day—through the products they use, the food they eat and the environments they live in—but only a fraction of those chemicals have been fully tested for safety.
Early childhood educators speak differently to boys compared to girls in toddler classrooms, University of Queensland research has found.
The world's urban population increased by 785 million people between 2000 and 2020, but that tells only part of the story. Now, a research team including an expert from the University of Michigan has dug into the demographics of more than 10,000 individual cities to obtain
An international team of scientists has demonstrated how powerful thunderstorm complexes over the U.S. Corn Belt are fueled by moisture rising from the region's fertile fields or just beneath them. The findings can lead to better and longer-term weather forecasts for this
Ads generated by artificial intelligence are nearly indistinguishable from human-made ones, but new research shows they consistently underperform compared to human-made work when it comes to predicting short-term sales impact.

The St. George's mushroom (Calocybe gambosa) is a popular edible mushroom, usually picked in May. Unfortunately, however, it also carries a risk as it can easily be confused with the young deadly fiber cap, which can potentially lead to fatal poisoning. The reason for this is
Researchers at The University of Texas at Austin have uncovered key principles that govern how DNA "origami" structures fold, findings that could make nanoscale materials faster and easier to manufacture. DNA origami is a technique that uses strands of DNA to self-assemble into
Ascidians, also known as sea squirts, are the evolutionary link between vertebrates and invertebrates, making them valuable subjects of biological studies. For the first time, researchers at Ruhr University Bochum have detected pronounced autofluorescence in Halocynthia
A Brazilian study published in the journal Ecography indicates that the biodiversity of anuran amphibians (toads and frogs) on islands is determined by factors encompassed in two previously opposing theories.

Bats are the only mammals that can actively fly, enabling many species to perform seasonal migrations. In migratory birds, remaining airborne for many hours is supported by burning fatty acids, something most mammals are incapable of.
Researchers at VIB, Ghent University, and VUB have uncovered how two proteins essential for immune cell development work together at the molecular level. The findings provide important insights into a critical mechanism that mediates the integration of molecular signals
Academic success depends largely on social background—this has long been known. A recent international study led by researchers at Leuphana University of Lüneburg now shows that young people's attitudes toward environmental protection are also strongly influenced by their
