Archaeologists unearth ‘masterpiece’ sealstone in Greek tomb

Archaeologists unearth ‘masterpiece’ sealstone in Greek tomb

From Science Daily In the more than two years since University of Cincinnati researchers unearthed the 3,500-year-old tomb of a Bronze Age warrior in southwest Greece, an incredible trove of riches has emerged, including four gold signet rings that have challenged accepted wisdom among archaeologists about the origins of Greek civilization. But that wasn’t the […]

Potential treatment to stop glaucoma in its tracks

Potential treatment to stop glaucoma in its tracks

From Science Daily Vision scientists at the University of California, Berkeley, and the University of Toronto have discovered that naturally occurring molecules known as lipid mediators have the potential to halt the progression of glaucoma, the world’s second-leading cause of blindness. Their findings, to be published Nov. 6 in the Journal of Clinical Investigation, mark a […]

How to lower stress with half the exercise

How to lower stress with half the exercise

Exercising with a friend might be better for your health than exercising all alone, reducing stress and improving quality of life. New research suggests that group exercise, such as in a fitness class setting, may reduce stress by about a quarter but people who go solo may not see any change at all. The study, […]

Scientists show how wormholes could be real

Scientists show how wormholes could be real

A new theory about black holes can solve both a conundrum and a paradox — how do we find out what’s inside a black hole and what happens to these space suckers at the end of the universe? Scientists have proposed a concept in which a quantum connection between two black holes can hold open […]

Daydreaming is good: It means you’re smart

Daydreaming is good: It means you’re smart

From Science Daily A new study from the Georgia Institute of Technology suggests that daydreaming during meetings isn’t necessarily a bad thing. It might be a sign that you’re really smart and creative. “People with efficient brains may have too much brain capacity to stop their minds from wandering,” said Eric Schumacher, the Georgia Tech […]

Mars study yields clues to possible cradle of life

Mars study yields clues to possible cradle of life

From Science Daily The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth. A recent international report examines observations by NASA’s Mars Reconnaissance Orbiter (MRO) of massive deposits in a basin on southern Mars. The authors interpret […]

3-D quantum gas atomic clock offers new dimensions in measurement

3-D quantum gas atomic clock offers new dimensions in measurement

From Science Daily JILA physicists have created an entirely new design for an atomic clock, in which strontium atoms are packed into a tiny three-dimensional (3-D) cube at 1,000 times the density of previous one-dimensional (1-D) clocks. In doing so, they are the first to harness the ultra-controlled behavior of a so-called “quantum gas” to […]
