Caffeine may make sleep less restorative even when you fall asleep normally and stay in bed for eight hours, with EEG recordings revealing fewer of the slow brain waves associated with deep sleep. Individual sensitivity varies dramatically, meaning eve…

A minimally invasive procedure called genicular artery embolization could offer a new middle ground between conservative treatments and knee replacement for osteoarthritis. By blocking tiny blood vessels associated with inflammation, GAE can significan…

Stanford researchers have recorded the first real-time quantum jumps of sound, watching single phonons abruptly vanish from one energy state to another. The breakthrough could open new paths for quantum computing, error correction, highly sensitive bio…

Researchers observed a humpback whale mother staying beside her presumed stillborn calf for hours and possibly days off Australia’s Gold Coast. She maintained eye contact and remained close to the calf in behavior resembling caregiving and nurturing. S…

A new AI control system lets MIT’s tiny flying robot move with insect-like agility, boosting its speed by about 450 percent and allowing it to pull off 10 somersaults in 11 seconds. The technology could eventually enable miniature robots to search eart…

Researchers have created a concrete mixture that is both stronger and capable of absorbing carbon dioxide. The best formula, combining zeolite with bamboo biochar, boosted compressive strength by 7.48% and tensile strength by 15% compared with conventi…

An amateur astronomer searching satellite maps for a Quebec camping spot accidentally discovered a massive ancient impact crater. Scientists later found shatter cones that confirmed the 25-kilometer-wide structure was blasted into Earth roughly 390 mil…

A Yellowstone super-eruption would begin not with a sudden surprise, but with weeks of increasingly alarming warning signs such as migrating earthquake swarms, rapid ground uplift, changing geysers, and rising volcanic gases. In a worst-case scenario, …

Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that tar…

Genetic evidence has revealed a previously unknown gentoo penguin species on the remote Kerguelen Islands and shown that gentoos actually consist of four distinct species. The discovery also highlights a growing threat, as warming oceans could leave se…

Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar app…
