Advances in structural biology have allowed scientists to determine molecular structures with atomic‑level detail, sometimes yielding static snapshots that do not reflect the dynamism of proteins. However, these motions are often crucial for biological function. Researchers from the Institute of Science and Technology Austria (ISTA) together with international collaborators have now combined several methods to shed light on how proteins ‘breathe’ and how some experimental techniques freeze their motion. The findings—which could boost protein design approaches and improve AI-based structural prediction tools—were published in Nature Chemistry.

Most Americans, even those who most appreciate AI, strongly support more regulation of it, a new survey by Johns Hopkins University researchers finds.

More than 70% of Americans want the right to interact with a human rather than an AI in medical, legal, educational and government settings. This proposed regulation and others were endorsed across party lines and by both regular users of AI and novices.

Diagnostic laboratories are central to disease surveillance and epidemic preparedness, yet poor adherence to biosafety and biosecurity protocols can put laboratory staff, communities and the environment at risk. This study assessed biosecurity and biosafety practices in 96 public and private biomedical and veterinary laboratories in Benin. Using a cross-sectional design, biomedical laboratories were evaluated with the Biosafety and Biosecurity in Laboratory Tool, while veterinary laboratories were assessed using the Laboratory Mapping Tool. Data were collected through KoBoCollect and analysed using R. Most laboratories showed poor compliance with established guidelines: 42% were classified as very high risk, 38% as high risk, 15% as moderate risk and only 5% as low risk. Strengthened policies and targeted capacity-building for laboratory staff and managers are urgently needed.
