Depression in later life may be an early warning from the brain, appearing years before Alzheimer’s begins to affect memory and thinking A new study in JNeurosci found that faster accumulation of tau, a protein closely tied to Alzheimer’s, was associated with worsening depressive symptoms in older adults who remained cognitively healthy.

Physicists Find Useful Energy Hiding in Quantum “Waste Heat”
A new theoretical approach helps connect quantum physics with classical thermodynamics by clarifying what counts as heat and useful work in tiny quantum machines. When a machine is reduced to a single atom and particles of light, even basic concepts such as heat and useful work become difficult to define. This problem sits at the […]

Scientists Discover the 7 Stages a Meteoroid Goes Through Before Hitting Earth
An analysis of 75 meteorite falls identified seven distinct processes that occur as space rocks melt, break apart, and slow down before reaching the ground. A space rock entering Earth’s atmosphere does far more than simply “burn up.” By examining 75 meteorite falls recorded in videos and photographs, researchers identified seven distinct stages that shape […]
Scientists Bring a Galápagos Plant Back From the Brink of Extinction
The Galápagos snapdragon, once close to disappearing, is showing encouraging signs of recovery through a long-term partnership between the Charles Darwin Foundation and the Galápagos National Park Directorate. For decades, the Galápagos snapdragon was known from little more than a specimen pressed into an herbarium collection. It had been gathered near Caleta Tagus in 1962, […]

Scientists Discover a Bacterial Molecule That “Disarms” a Dangerous Fungus
A bacterial molecule called gladiolin can disarm invasive Candida albicans and strengthen the effects of a major antifungal drug. Candida albicans usually lives harmlessly in the human body, but under the wrong conditions it can transform into an invasive form capable of damaging tissue and causing life-threatening infection. Researchers from Monash University and the University […]
Scientists Discover a Hidden Defect That Could Explain Why IBD Keeps Coming Back
A hidden molecular defect in inflammatory bowel disease may help explain why flare-ups can return even when patients appear well. Even when inflammatory bowel disease appears under control, intestinal cells may remain primed to die. In a WEHI-led study, researchers found this hidden molecular defect in patients with few or no symptoms, and higher levels […]
