Kids and teens are going to AI chatbots for advice. How can parents make sure this is safe?

Last week, Australian Federal Police Commissioner Krissy Barrett warned artificial intelligence (AI) chatbots are not a sufficient replacement for human support for children. The comment was in response to a recent Adelaide University study that found more than one in three Australian children turn to AI chatbots for support when they are sexually victimized online or otherwise tell nobody at all.

The force behind our strength: How mechanical processes regulate muscle development

Skeletal muscles grow and regenerate as individual precursor cellsβ€”called myoblastsβ€”fuse into long fibers from which mature muscle fibers develop. How they coordinate this process and form functional muscles is not yet fully understood. A research team at the Max-Planck-Zentrum für Physik und Medizin (MPZPM) has now shown that mechanical stress influences the fusion of muscle cells.

AI and wastewater DNA-based mapping help identify sewer pipes at risk of corrosion

Underground sewers that safely manage wastewater are essential to modern cities. However, since they are buried underground and difficult to access, their condition can be hard to monitor. Traditional camera inspections are costly and time-consuming, but we need regular inspections so aging pipes do not continue to deteriorate until they reach a breaking point. When damaged pipes leak, they can pose serious risks to public health by contaminating surrounding water, while more severe failures can even damage infrastructure above them, causing sinkholes in city streets.

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 β€œPac-Man” enzyme with a surprising secret

Scientists have discovered a remarkable β€œPac-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 failβ€”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.
