Shredded star reveals a massive black hole wandering far from its galaxy's center

Astronomers have discovered a star being torn apart by a massive black hole more than 1,000 parsecs from the center of its host galaxy. The tidal disruption event, TDE 2023mfm, was first discovered by ZTF and then studied with a wide range of telescopes, including Keck, Lick, Hubble, Swift, Chandra, XMM-Newton and the VLA. The discovery paper was posted to the arXiv preprint server on Sept. 28.

USC scientists discover how to create a never-ending supply of cancer-fighting cells

USC scientists have discovered a way to create a potentially renewable supply of genetically engineered immune cells that can attack cancer and strengthen the body's natural defenses. By growing and modifying immature immune cells rather than mature ones, researchers developed a system that can continuously produce tumor-fighting cells inside the body.

The uranium cubes that exposed Nazi Germany’s nuclear failure

Scientists investigating Nazi Germany's secret nuclear program have uncovered evidence that its final experimental reactor was nowhere near as close to working as previously claimed. Analysis of surviving uranium cubes and wartime documents reveals that Germany lacked the enormous quantities of uranium and heavy water needed to make its reactor operational.

Yale scientists discover how stress changes the brain to make memories stronger

Yale scientists have uncovered how the stress hormone cortisol helps the brain turn emotional experiences into stronger, longer-lasting memories. The discovery reveals that stress can reshape communication between brain networks involved in emotion and memory, potentially explaining why certain moments are so difficult to forget.

Scientists discover a plastic-eating “Pac-Man” enzyme with a surprising secret

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.

Astronomers discover the first-ever green star, plus the reddest 'white dwarf' ever seen

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 ...

NASA captures strange waves high above Hurricane Simon

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.

Performance under pressure: A new perspective on why we fail—or rise to the occasion

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.

A protein that fuels cancer could also be the key to fighting it

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.

First in-depth map of 'forever chemicals' in the Finger Lakes created

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.

Endangered species in Canada face extensive delays receiving protection

For more than 20 years, Canada's Species at Risk Act (SARA) has protected wildlife that are at risk of being lost from Canadian lands and waters. Once a species is listed as extirpated, endangered or threatened under the act, it becomes illegal to kill, harm or capture it or damage its residences. Its critical habitat must also be protected, at least on federal land.
