fahrbot-bot shares a report from Smithsonian Magazine: The brain is one of the first organs to begin decomposing after death. Yet archaeologists have discovered more than 4,400 preserved human brains around the world, some of which have remained intact for the last 12,000 years. In hundreds of cases, the brain was the only soft tissue left among otherwise skeletal remains. But how and why do brains sometimes persist for millennia while all other types of soft tissue disappear? This preservation paradox has stumped scientists for years. Now, however, a team of researchers say they may have solved the mystery. If a brain ends up in a wet, oxygen-starved environment, the processes that usually cause decay can have the opposite effect, researchers report in a study published in the August 7 issue of the Journal of Proteome Research. "Under the right conditions, preservation actually arises from decay itself: The same reactions that degrade tissue can also weld the breakdown products

An anonymous reader quotes a report from Ars Technica: Antibodies play a central role in your body's immune defense. But they're also nearly ubiquitous in biological research, being essential for several widely used lab techniques. While some researchers need to go through the process of producing their own antibodies, antibodies to many key proteins are commercially available and can be ordered for overnight delivery. In May, however, Reese Richardson, a post-doc at Northwestern University, discovered that some of the images used to demonstrate how these antibodies performed in lab experiments had been subject to image manipulation -- the sorts of changes that would get a paper retracted if they had appeared in the academic literature. The manipulations ranged from removing background noise to copying and pasting data to fabricate results. Now, he has done a more exhaustive search and found problematic manipulations in images used to market over 17,000 commercial antibodies. [...] T

New Zealand has introduced legislation that would ban children under 16 from social media platforms and AI companion services. "We have protections to keep children safe in the real world and we need them in the virtual world too," said Prime Minister Christopher Luxon in announcing the bill. Jurist.org reports: The Online Safety (Minimum Age and Child Safety Risk Assessment) Bill would require an age restriction on platforms with harmful features for children. These features include recommender systems, endless feeds, feedback features and time-limited features. The bill also seeks to restrict underage users from accessing AI companion services. However, it explicitly excludes messaging apps, professional networking sites, gaming and music platforms, and other educational and health tools. Notably, age verification through self-declared dates of birth and formal identification does not satisfy the platforms' duty under the law. It also requires platforms to verify their us
