Scientists have discovered evidence of two hidden magma sources beneath Nicaragua’s Masaya volcano, where satellite observations revealed mysterious ground movements suggesting magma is shifting deep underground. The findings could improve eruption forecasting for the active volcano, which sits near 2 million people and attracts tourists to its spectacular lava lake.
Scientists have uncovered a possible explanation for why some people struggle to taste food more than a year after recovering from COVID-19. By examining taste buds from patients with lingering symptoms, researchers discovered molecular abnormalities that weaken the signals responsible for detecting sweet, bitter, and savory flavors.
Walking just 3,000 steps a day could help slow Alzheimer’s-related brain changes, according to new research. Scientists discovered that physical activity was linked to less buildup of harmful tau proteins and nearly half the cognitive and functional decline, even in people already showing early signs of the disease. The strongest benefits appeared at 5,000 to 7,500 daily steps, suggesting that the popular 10,000-step goal may not be necessary.
Scientists have discovered that severely bleached corals can make a remarkable comeback simply by touching healthy, genetically identical corals. In laboratory experiments, dying corals regained their color and fully recovered within seven weeks, with as little as five days of contact sometimes enough to start the healing process.
Astronomers have uncovered a surprising rainbow of dead stars, including the first known star that would appear genuinely green to human eyes. Researchers found that white dwarfs can glow in unexpected shades of pink, purple, yellow, and cyan because of unusual chemical interactions in their extremely dense atmospheres.
A discovery in tiny algae led to a Nobel Prize-winning breakthrough that allows scientists to switch brain cells on and off using light. The revolutionary technique has already helped researchers activate memories and is opening new possibilities for restoring vision and treating brain disorders.
Scientists have uncovered an unexpected culprit behind sleep loss in Alzheimer’s disease: overactive immune cells in the brain. By temporarily removing these cells, researchers restored more than two hours of sleep per day in mice, revealing a promising new target for treatment.
A common liver disease affecting nearly 30% of adults worldwide may be far more complicated than scientists previously realized. Mayo Clinic researchers have discovered that fatty liver disease actually consists of five distinct biological subtypes, each carrying different risks for liver failure, cancer, heart disease, and other serious complications.
Researchers have identified striking parallels between Sigmund Freud’s century-old theories and modern neuroscience, suggesting that the brain’s constant predictions shape how we experience reality. The findings could help explain why harmful thought patterns are so difficult to break and offer new insights into treating mental disorders.
Archaeologists have discovered a faience workshop at a major temple complex in the ancient Nubian capital of Napata, showing how the rulers of ancient Kush used specialized craft production to reinforce royal power.
