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 ...

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 ...

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.

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 ...

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 ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) is a partner, have captured the first direct, high-resolution ...

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.

Scientists have long been fascinated by two promising classes of antibiotics that disable RNA polymerase (RNAP). They knew that these drugs could grind gene expression to a halt in several pathogens, including the bacterium ...

Transporting molecules across biological membranes is essential for life. In nature, this can occur through passive transport, known as diffusion. "Biological systems often use mechanical motion to accomplish tasks that cannot ...

Communities living in Colombia thousands of years ago achieved an engineering wonder of the world based on cooperation among family groups without top-down government, a new study shows. Archaeologists argue that policymakers ...

Platypuses rescued during a severe drought quickly returned to their old routines after being released back into the wild, suggesting emergency rescues can help protect vulnerable populations.

A joint research team—led by professor Young Seok Cho from the School of Medicine, alongside professor James J. Moon from the University of Michigan—has developed the world's first oral, microbiome-based nanomedicine. By ...
