Science and HealthAI-designed SARS-CoV-2 variants escape prevalent antibodies
While headlines warn that AI could unleash future biological threats, the technology also offers our best defense: a way to anticipate viral evolution and stress-test treatments. Rather than waiting for SARS-CoV-2 to mutate and outrun our immune system, my colleagues and I at École Normale Supérieure and Institut Pasteur built EscapeMap. Published in Cell Systems, our framework generates highly mutated, functional viral proteins to evaluate therapeutics against future evolutionary trajectories long before those mutations surface in the real world.

Science and HealthProlonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal scaffolding and, in the process, release their nuclei from a protective keratin network.

Science and HealthResearchers identify useful tool for diagnosing endocrine dysfunction in sick foals
Researchers have found that an arginine vasopressin stimulation (AVP) test offers a reliable way to assess endocrine function in sick foals. The work, published in the Journal of Veterinary Internal Medicine, could lead to faster identification and treatment, improving survival rates for foals with hypothalamic-pituitary-adrenal gland axis (HPAA) dysfunction.

Science and HealthNASA Science Soars During August Total Solar Eclipse
Each time the Moon covers the Sun during a total solar eclipse — darkening daytime skies and briefly revealing the Sun’s ethereal outer atmosphere, the corona — it presents new opportunities to better understand our star and its influence on Earth. On Wednesday, Aug. 12, as the next total solar eclipse sweeps over Greenland, Iceland,
