Researchers have unveiled a paper-thin swimming robot powered by living muscle cells rather than motors. The soft robot can navigate its way through a watery maze, showing how engineered biological tissue can be used to drive tiny machines. The work highlights progress in biohybrid robotics, where living cells give devices flexibility and responsiveness that conventional actuators cannot match.

Anthropic is facing questions over claims that its AI systems achieved a significant breakthrough in biology. CNET asked working scientists to assess the claim, and reactions appear divided, with experts urging caution about how such achievements should be interpreted and verified. The debate touches on a broader tension in AI research: how to evaluate dramatic capability claims when independent validation in complex scientific fields is slow and difficult.

National Guard units are conducting training exercises to prepare for chemical and biological threats. The teams are practicing detection, protection and response procedures for hazardous-material incidents. The training highlights the Guard's civil-support role in dealing with attacks or accidents involving dangerous agents, and it is drawing attention as a military capability relevant to domestic preparedness.

Anthropic says its biology lab has already found something big, according to a TechCrunch report. The company has not publicly detailed the nature of the finding, which is being linked to its AI-driven research efforts. Reaction online is limited so far, with readers largely debating what the announcement could involve and waiting for more concrete results from the lab.

A new study reports that people with internet addiction show signs of exhausted physiological stress systems, suggesting heavy compulsive internet use may wear down the body's stress response. The finding is drawing attention among health researchers and commentators, who say it adds biological evidence to concerns about excessive screen and online use affecting physical health, not just behaviour or mood.

Chemists report finding a crown-shaped sulfur ring inside mammalian cells, according to Chemical & Engineering News. The structure, an eight-membered sulfur ring, was reportedly observed directly in living cells, a rare detection given sulfur compounds' instability and difficulty of measurement. The finding could reshape understanding of sulfur chemistry in biology and how such molecules form and persist inside cells.

Estonia has announced a partnership with French AI biotech company Owkin to advance sovereign AI capabilities in biology and life sciences. The collaboration aims to strengthen Estonia's control over its biological data and AI infrastructure. Further details about the scope and funding of the agreement have not yet been made public.

A report from the Genesis Mission initiative examines how artificial intelligence is being applied to fusion energy research and biological design. The document highlights the role of AI and high-performance computing in accelerating scientific discovery in these fields. Details of the report's specific findings and the response from researchers have not yet been widely reported.

New reporting highlights how soil biology could help Canadian winter wheat farmers use nitrogen more sustainably. Researchers point to the role of soil microorganisms in naturally supporting nutrient availability, which could reduce reliance on synthetic fertiliser while maintaining yields. The topic matters as agriculture faces pressure to cut fertiliser emissions and input costs.

A new commentary in Nature examines the growing intersection of synthetic biology and bioprocess engineering. The piece highlights how designed biological systems are increasingly being integrated into industrial-scale production, requiring closer collaboration between engineers who optimise manufacturing and biologists who build novel organisms. The discussion matters for sectors including pharmaceuticals, biofuels and sustainable materials, where scaling laboratory breakthroughs into viable commercial processes remains a key bottleneck.

Researchers at the University of Cambridge report that sex differences in attention can be detected in newborns, suggesting the differences emerge far earlier in development than previously thought. The finding is drawing attention online, with readers debating what it means for the long-running discussion over how biological and environmental factors shape cognitive differences between males and females.

A reported experiment in which scientists applied pressure to a leg bone appears to have contributed to healing in the brain, an unexpected connection between the two. The finding suggests that physical stimulation of bone tissue may trigger biological responses that aid neurological recovery. Details about the researchers, method, and results remain limited, but the surprising link between a limb and brain repair is drawing curiosity.
