A new Cornell University study finds that weak AI regulation may be worse than no regulation at all when it comes to the safety of AI products and services.

Across 21 studies, researchers confirmed that people learned attitudes from a single trust interaction, whether positive or negative. But negative experiences were harder to dispel. The rise in distrust after a negative experience was about double the boost in trust after a good exchange. Surprisingly, the same effects did not occur when people interacted with artificial intelligence, because participants did not see those interactions as social.

Many neurological diseases damage specific parts of the brain, even though the harmful protein involved is present throughout the brain. Researchers report new evidence that explains these differences in brain tissue vulnerability.

About The Study: Results of this cohort study show that long-term exposure to road traffic noise was associated with higher Parkinson disease risk. Having a quiet facade mitigated this association. These findings suggest noise as a novel risk factor for Parkinson disease and support mitigation strategies ensuring a quiet residential side.

Scientists at Murdoch University have read the full genetic code of bacteria from the salt lakes of Wadjemup (Rottnest Island), giving them their clearest picture yet of how these tiny organisms could be used to make biodegradable plastic. Until now, scientists have mostly relied on rough, incomplete versions of their genetic code, which made it hard to know exactly what these bacteria could do. By reading every letter of the genetic code, the team could point to the exact genes that can make plastic, see how they are set out, and confirm they had barely changed over a very long time. This is significant as having a precise map turns these bacteria from an idea into something scientists can work on and fine-tune.
