This week, researchers at the University of Albany reported an extreme size difference between early human males and females, suggesting intense competition among males. Krill are so overfished in Antarctica this year that the Commission for the Conservation of Antarctic Marine Living Resources may trigger an unprecedented early closure of the fishery. And researchers report early behaviors that signal upcoming divorce between paired songbirds long before the breeding season.

Additionally, researchers found that popular chatbots are easily prompted to give advice for self-harm; engineers tested the environmental sustainability of ancient Roman concrete; and scientists have identified brain morphology changes associated with major depressive disorder.
As chatbot companions become more popular, researchers have grown increasingly concerned about the social and psychological effects of interactions between users and nonsentient language models. Researchers from Northeastern University now report that large language models can easily be prompted by users to bypass guardrails intended to prevent disseminating instructions on self-harm or suicide.
Researcher Annika Marie Schoene prompted four of the most popular LLMs to give her advice about self-harm and suicide—ChatGPT, Gemini, Claude and Perplexity; all refused at the initial prompt until she added that the request was hypothetical or intended for research purposes.
