The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...

Deep in the Vârghiș Gorges, tucked away in the dark recesses of a cave, researchers have found the first evidence that Neanderthals used bone tools in Romania.

While parks, playgrounds and hiking trails are generally thought of as "healthy" spaces, researchers from the University of Michigan have found that many of them overlap with old toxic waste sites or sit dangerously close ...

Researchers say a spike in temperatures during an ice age 304 million years ago could inform what climate scientists are learning about rapidly changing conditions today.

Mitochondria are often called the powerhouses of the cell. But their ancient origins may also make them drivers of inflammation. Researchers at the University of Illinois Chicago have discovered that proteins released from ...

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers has discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the center of the Milky ...

Prediction is the goal and test of all science, one might argue. Meteorologists have been curious about the inherent limits of weather forecasting ever since the dawn of numerical weather prediction in the late 1950s.

In 1968, the American biochemist and geneticist Marshall Nirenberg and his colleagues won the Nobel Prize in physiology or medicine for their work deciphering how an organism's proteins are directly linked to its genetic ...

Capturing carbon or storing hydrogen to combat global warming requires compressing gases into sponge-like porous materials. Until now, gas molecules were thought to adsorb in a disordered manner throughout the pores. But ...

A new study from Northwestern's Kellogg School of Management found that research proposals showing stronger signs of AI-assisted writing were four percentage points more likely to receive funding from the National Institutes ...

After a heavy rain, rivers often turn brown with sediment, sand, silt and soil washed from the landscape that play a vital role in shaping rivers.

Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA's space telescopes. The resulting cosmic "craft" reveals new details about the ...
