A negative scan does not always mean recurrent prostate cancer is nowhere to be found. Sometimes, the disease may simply be too small or too faint to appear yet. New research suggests that repeating a PSMA PET scan later can reveal cancer that was missed the first time. Among patients with rising prostate-specific antigen (PSA) […]

New research suggests that low oxygen levels may help alleviate disease caused by defects in mitochondrial quality control. Oxygen is essential for people—and most other organisms—but more is not always better. When oxygen accumulates beyond what cells can safely use, it can become toxic and contribute to serious health problems. In the brain, excess oxygen […]

Researchers have developed a visible-light-driven method that could help chemists build more complex drug-like molecules in fewer steps. A blue light commonly used in aquariums and indoor gardens could help chemists solve one of drug discovery’s persistent challenges: building more intricate molecules without adding a long series of costly reactions. Many medicines are based on […]

A reverse prediction test suggests that supposedly brainlike AI models may rely on visual strategies the primate brain does not use. Artificial intelligence can sometimes predict how the brain responds when people recognize objects. But that resemblance may hide an important weakness: the internal workings of today’s vision models do not necessarily match the processes […]

A leaf-eared mouse living more than 6,700 meters (22,000 feet) above sea level in the Andes has shattered assumptions about where mammals can survive. Near the summit of an Andean volcano, where the air contains barely half as much oxygen as it does at sea level, scientists found something that should not have been there: […]

Aging appears to alter how key cerebellar neurons fire, with measurable effects on movement and coordination. Aging often brings slower movement, weaker balance, and reduced agility, but the brain changes behind these losses have been difficult to identify. McGill University researchers have now directly linked declining activity in Purkinje cells, an important type of neuron […]
