Scientists have discovered a remarkable “Pac-Man enzyme” that helps bacteria devour certain types of plastic and may offer new hope in the fight against plastic pollution. Researchers found that several biodegradable plastics completely broke down in soil within about a year, while conventional plastic remained largely unchanged.
Stellar cores called white dwarfs come in an astonishing array of colors, including what scientists say is the first known green star and the reddest star ever found, new research reveals.A white dwarf star is the dense, cooling core that remains after a low- to medium-mass star runs out of fuel. The new study, published Thursday (Oct. 15) in the journal RAS Techniques and Instruments, shows that white dwarfs come in far more colors than their name suggests.White dwarf stars got their moniker because the first known examples glowed in either white or pale blue. The new study, however, suggests that "white" dwarfs also emit visible-light colors like pink, green, cyan, purple and yellow."Most ...
Experts unpack the science of screen addiction and how to build a healthier relationship with technology
Future Arctic winter sea ice is likely to shrink by around 1 million square kilometers (386,000 square miles) more than previously thought, after researchers used clues from a warm period 6,000 years ago to improve the reliability of climate models.
If you’re trying to avoid the worst of cold and flu season, looking after your mind can help shape your immune system, finds columnist David Robson
AI has taken huge strides in computer programming and mathematics – physics could be next
As Hurricane Simon unleashed destructive winds and flooding along Mexico’s coast, NASA satellites captured an extraordinary sight: massive atmospheric waves rippling high above the storm. The rare images reveal how powerful hurricanes can disturb the upper atmosphere, creating patterns that are usually invisible from space.
The decisive penalty kick in a final, match point in tennis or the last attempt in a competition: When a lot is at stake, even a well-practiced performance can suddenly break down. Yet pressure does not necessarily impair performance. Some people perform at their best precisely in the moments that matter most. Existing accounts can only partly explain why.
Scientists have discovered how to turn a protein that normally fuels cancer growth into a weapon against it. By activating PPARD in immune cells, researchers made them better at burning fat and attacking tumors, slowing or stopping cancer growth in laboratory experiments. The approach showed promise against colorectal, breast, and ovarian cancers, as well as melanoma.
Scientists discovered that atomic steps just one atom high can guide quantum vortices through superconductors, making them move more than 1,000 times more easily in one direction than another. This remarkable control over quantum motion could lead to a new generation of ultra-efficient superconducting electronics.
A nationwide search for giant crayfish uncovered a record-breaking Tennessee specimen and a surprising mystery about how big these freshwater creatures can grow. Scientists found that North American crayfish seem to hit a biological size limit, possibly because of their muscles or protective shells.
In 2023, professor Damian Helbling was getting a lot of calls and emails from local residents. The Environmental Protection Agency (EPA) had just announced regulations to limit per- and polyfluoroalkyl substances (PFAS)—some of which have been linked to cancers and other negative health effects—in drinking water. Ithacans and others in the region wanted to know about levels in the ponds, lakes, streams and creeks in their proverbial backyards.
