Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly reactive—they act like oxygen delivery trucks, transferring atoms to other
The twinkling stars in the night sky are not just beautiful to look at. Their flickering reveals something about the varying temperatures and densities in the layers of Earth's atmosphere, which refract the light as it travels toward us. Certain stellar remnants that emit radio
A new study published in the May 2026 issue of the American Economic Review and authored by an international group of researchers gives a different perspective on how production and financial networks are at interplay. The research develops a framework that integrates two key
Rice plants and Venus flytraps share something in common that was not scientifically documented until recently. Using a faint smell to lure caterpillars into a trap, rice plants killed early-stage fall armyworm larvae by trapping them in a spikelet, the part at the end of a
In physics, the spontaneous de-mixing of two substances is known as phase separation. It is an important mechanism in nature to create structure and patterns and typically requires some form of attraction between the constituents. Researchers at the Max Planck Institute for
Researchers have developed a technique to analyze how black holes "ring" when they collide and merge: one of the universe's most dramatic events. When black holes merge, the collision produces a new, larger black hole that "rings" like a plucked guitar string or a bell while it
Can we have higher yields and better taste? Using a natural extract from the fungus Pseudozyma aphidis, this method improves the firmness and natural sugar content of crops like tomatoes and melons while significantly boosting production. This discovery offers a practical path
Have you ever wondered how a fly manages to dodge you in a split second? Scientists have long been fascinated by the lightning-fast reflexes that help flies escape danger almost instantly. But despite decades of research, they still don't fully understand exactly how the brain
Two bald eagles hatchlings have been spotted in a nest in a Chicago park in what city officials believe is the raptors' first successful wild breeding in the Windy City in more than a century.
Sea levels are rising not only on average, but also in their seasonal fluctuations. This is a lesser-known trend that could have major consequences for mudflats, salt marshes and other coastal ecosystems. Researchers from the Netherlands and Flanders describe these findings in
Buffalo's legendary snowfall totals are largely the result of one unlucky geographic reality: the city sits east of the Great Lakes instead of west. Anyone who has lived through a winter in Buffalo, Cleveland or any snowbelt city knows that prevailing westerly winds pick up
A research team at TU Wien has succeeded in modifying known materials in such a way that they possess new, desirable properties. These materials are expected to find application in the field of thermoelectricity.
As digital nomads rethink where to live, researchers are exploring whether their choices can help close Europe's urban-rural divide. New research suggests the shift to remote working could support rural regions, but only where infrastructure and policy align.
Artificial intelligence (AI) systems affect many parts of daily life, including health care, education, and public policy, but the public has had few meaningful opportunities to participate in the development, governance, or modifications of AI systems, according to Tanusree

Amines are a functional group characterized by the presence of a nitrogen atom bonded to one or more alkyl or aryl (aromatic ring) groups. Derived from ammonia, amines play crucial roles in biological systems and various industrial applications. In everyday life, they can be
The Andes type of the hantavirus is spread by “close contact,” but it’s unclear how much of that transmission occurs by inhaling airborne droplets or other means
An international team led by researchers at University of California San Diego and University of California, Riverside has developed a free, web-based platform designed to make public metabolomics data more accessible. By allowing users to search for chemical structures across
Astronomers led by the Center for Astrophysics | Harvard & Smithsonian (CfA) have made the first direct detection of turbulence distorting light in the interstellar medium. The findings will help scientists achieve clearer imaging of the supermassive black hole at the center of
Horses were being ridden, worked, and traded long before anyone thought it possible. New research pushes back the accepted timeline of human use of horses by centuries, showing that humans used horses in organized ways as early as the 4th millennium BCE, if not earlier. The
Gene editing can repair a DNA error in mice that causes Dravet syndrome, a rare, incurable, and potentially deadly form of childhood epilepsy. After the edit, the mice have far fewer seizures and live much longer. As published in Science Translational Medicine, the results
Current indices for assessing the biological status and quality of rivers are designed to study perennial rivers, so they are not suitable for temporary rivers. This is because the lack of a constant flow of water in the riverbed affects the connectivity and dispersal of
NASA's TESS (Transiting Exoplanet Survey Satellite) has released its most complete view of the starry sky to date, filling in gaps from previous observations. Nearly 6,000 colored dots scattered across the image show the locations of either confirmed or candidate
When Ted Lasso became the coach of last-place AFC Richmond on a popular television show, he jumped in with a can-do coaching style that ignited a team ready for change. Like Lasso, new leaders are more likely than their predecessors to improve motivation and organizational
A Neanderthal tooth shows clear signs of human intervention to treat bacterial decay, showing that the earliest dentistry began at least 59,000 years ago
Daphnia, also known as water fleas, are artists of defense. When their predators live nearby, the water fleas change their body structure to make themselves more difficult to eat. Professor Linda Weiss from Ruhr University in Bochum, Germany and her team have identified a
Storm petrels are among the smallest and most mysterious seabirds. Until recently, the use of biologgers to track their movements was impossible. A new study published in Biology Letters reveals that they routinely travel hundreds of kilometers while deliberately seeking
We hardly give them a second thought, but everyday objects like bags and backpacks belong to a long technological tradition that may stretch back hundreds of thousands of years.
A survey found that more than 60 percent of respondents “strongly support” making psychedelics easier to study, reflecting a growing consensus that some could have therapeutic use
