On July 16, 2024, a daytime meteor shook New York City with a sonic boom as it passed just south of the Statue of Liberty. Now, an international team of researchers reports in the journal Science Advances that a short time ...

Ancient DNA can be a powerful tool for helping us reconstruct the long-dead past. Most surviving genetic material comes from the bones and teeth of animals that lived in cold environments, where freezing temperatures help ...

Just as this country celebrated its 250th birthday, some geneticists were celebrating America, too. At the end of June, the National Institutes of Health announced its "All of Us" Research Program had become the world's largest ...

Plastic has become a ubiquitous part of modern life—in water bottles, shopping bags and car dashboards. But once discarded, it is among the hardest materials on Earth to recycle. Most recycling processes require plastics ...

For more than 150 years, fossils of Jurassic fish scattered across Europe's museums were studied and drawn by generations of scientists. However, when a paleontologist decided to shine an ultraviolet light on them, a hidden ...

Quantum computers promise to solve problems that would take even the fastest conventional supercomputers a vast amount of time, but the quantum information they store and process is extremely sensitive to even tiny disturbances ...

Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet's ice. These features emit a glow when sunlight bounces off dust and water droplets. ...

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the Supernova Cosmology Project, led by Saul Perlmutter, and the High-Z Supernova Search Team, led by ...

European astronomers have conducted optical and radio observations of an enigmatic radio source designated GRS 0917+75. As a result, they found that GRS 0917+75 is a giant radio galaxy and determined its properties. The new ...

Deep in the Atlantic Ocean, the Lost City hydrothermal field is known for eerie white chimney structures made of carbonate. Alkaline hot springs, loaded with hydrogen and methane, emerge from the seafloor there. Rather than ...

Many parts of Western Europe are currently wilting under a heat wave. These blistering spells can last for a week or more, and although they are common in most summers, it is difficult to predict how long they will last.

Shielding astronauts from the deadly radiation they face is a central challenge for any designer of a deep-space crewed mission. Even relatively low levels of exposure over long periods can lead to everything from central ...
