Journals Infiltrated With 'Copycat' Papers That Can Be Written By AI

4 weeks ago
An analysis of a literature database finds that text-generating AI tools -- including ChatGPT and Gemini -- can be used to rewrite scientific papers and produce 'copycat' versions that are then passed off as new research. Nature: In a preprint posted on medRxiv on 12 September, researchers identified more than 400 such papers published in 112 journals over the past 4.5 years, and demonstrated that AI-generated biomedicine studies could evade publishers' anti-plagiarism checks. The study's authors warn that individuals and paper mills -- companies that produce fake papers to order and sell authorships -- might be exploiting publicly available health data sets and using large language models (LLMs) to mass-produce low-quality papers that lack scientific value. "If left unaddressed, this AI-based approach can be applied to all sorts of open-access databases, generating far more papers than anyone can imagine," says Csaba Szabo, a pharmacologist at the University of Fribourg in Switzerland, who was not involved in the work. "This could open up Pandora's box [and] the literature may be flooded with synthetic papers."

Microsoft Brings Microfluidics To Datacenter Cooling With 3X Performance Gain

4 weeks ago
Microsoft has successfully tested a microfluidic cooling system that removed heat up to three times better than cold plates currently used in datacenters. The technology etches tiny channels directly into silicon chips, allowing cooling liquid to flow directly onto the heat source. In lab tests announced September 23, 2025, the system reduced the maximum temperature rise inside GPUs by 65%. The channels, roughly the width of human hair, were optimized using AI to create bio-inspired patterns resembling leaf veins. Microsoft collaborated with Swiss startup Corintis on the design. The cooling fluid can operate at temperatures as high as 70C (158F) while maintaining effectiveness. The company demonstrated the technology on servers running Microsoft Teams services, where the improved cooling enables overclocking during demand spikes that occur when meetings start on the hour and half-hour. Microsoft is investigating incorporating microfluidics into future generations of its first-party chips as the company plans to spend over $30 billion on capital expenditures this quarter.
