A major trial found that implantable cardioverter-defibrillators may benefit some patients younger than 70 with mild-to-moderate heart dysfunction and cardiac scarring. A more than decade-long randomized trial suggests that implantable cardioverter-defibrillators may benefit some patients who have heart scarring and only mild-to-moderate loss of heart function, a group that currently falls outside standard treatment guidelines.

Cardiac Breakthrough Could Offer Lifesaving Treatment to More Patients

Scientists Uncover New Clues Behind the “Suicide Headache” Mystery
Cluster headache causes extreme pain, but its origins remain unclear. New research links the disorder to genetics, inflammation, and tobacco smoke exposure. Unlike an ordinary headache, a cluster attack typically erupts without warning and causes excruciating pain around one eye. Episodes can last from 15 minutes to three hours and often return at similar times […]
Depression in Later Life May Be an Early Warning Sign of Alzheimer’s
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. Teodora Markova of […]
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, […]
