Something strange is happening beneath a volcano near 2 million people

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 discover why some people still can’t taste food after COVID-19

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.

Romans may have set fire to Celtic town during conquest to 'humiliate' the enemy, archaeologists find

Archaeologists have unearthed a Roman military camp in Spain, where they found fragments of weapons and metal tacks from soldiers' shoes. The camp was used during the Cantabrian Wars fought by Emperor Augustus as he expanded the Roman Empire in the first century B.C.The fortified military camp is made up of an earthen platform roughly 39 feet (12 meters) wide, which is surrounded by a stone perimeter wall about 5 feet (1.5 m) thick, according to a translated statement. Uncovered during excavations earlier this year, the camp is situated about one-third of a mile (500 m) from where an Iron Age settlement was once inhabited by the Cantabri people, a group of Celtic tribes that lived among the ...

Just 3,000 steps a day may help slow Alzheimer's, scientists find

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.

A simple touch can bring dying corals back to life in just 7 weeks

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 discover a ghostly green star unlike any known before

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.
