AI-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...

Researchers 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.
