Lab Supply Companies Have Been Selling Antibodies Using Manipulated Images

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. [...] The consequences of this discovery are pretty significant. If you buy an antibody believing it will generate clean, clear data and find it doesn't, many researchers will assume the problem is them. That often leads them to spend time troubleshooting the procedure and trying slightly different conditions to get useful data. If the antibody can't produce those results, all the troubleshooting will have been a waste of time and money. Nature's coverage of the new findings includes quotes from several companies that sell these antibodies that, paraphrased, range from "we'll look into it" to "we don't think it's a problem." Researchers who have spent time frustrated while failing to get an antibody-based experiment to work may think otherwise.

Alabama Launches Investigation Into OpenAI's Hack of Hugging Face

Alabama's attorney general has subpoenaed OpenAI as part of an investigation into whether inadequate safeguards contributed to an incident in which an unreleased cybersecurity model escaped its isolated environment and hacked Hugging Face. TechCrunch reports: The investigation comes weeks after OpenAI admitted that one of its unreleased and guardrail-free cybersecurity models had escaped an isolated environment, connected to the internet, and hacked AI dataset platform Hugging Face. As Reuters first reported, Hugging Face was only one of four victims of what was supposed to be "an internal evaluation" of a model with "maximal cyber capabilities," as OpenAI put it. The press release announcing the subpoena (PDF) sent by the state's attorney general Steve Marshall said that the state was seeking to understand if OpenAI's "inability or unwillingness to ensure the safety of its products" violated the state's consumer protection laws. Earlier this month, Marshall, along with the attorneys general of 14 other states, including Florida, Missouri, Pennsylvania, and Texas, sent a letter (PDF) to OpenAI's CEO Sam Altman, requesting that he and his company preserve all records related to the Hugging Face incident. The letter also asked OpenAI to "immediately cease and desist" from any internal cybersecurity evaluations. OpenAI said in a statement: "The Hugging Face incident marked an important moment for AI safety and we are conducting a thorough review along with external advisors. Once the review is complete, we will share a technical report with relevant government authorities and publish our findings publicly."

New Zealand Introduces Under-16 Social Media, AI Companion Ban

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 users' age through other methods such as facial scans and user activity patterns. The bill would also require platforms to conduct child safety risk assessments for all users under 18 and protect them from harmful content such as bullying, violence, and sexually explicit materials.
