Researchers at Berkeley Lab and their collaborators have honed a way to probe the quark-gluon plasma, the kind of matter that dominated the universe immediately after the big bang.

By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, “perfect fluid” that give clues to the state of the young universe just microseconds after the big bang. (more…)

The water in your bottle might be older than the sun

ANN ARBOR — Up to half of the water on Earth is likely older than the solar system itself, University of Michigan astronomers theorize.

The researchers’ work, published in the current issue of Science, helps to settle a debate about just how far back in galactic history our planet and our solar system’s water formed. Were the molecules in comet ices and terrestrial oceans born with the system itself—in the planet-forming disk of dust and gas that circled the young sun 4.6 billion years ago? Or did the water originate even earlier—in the cold, ancient molecular cloud that spawned the sun and that planet-forming disk? (more…)

Structure of face may help predict expression of prejudice, researchers report

The structure of a man’s face may indicate his tendency to express racially prejudiced beliefs, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

Studies have shown that facial width-to-height ratio (fWHR) is associated with testosterone-related behaviors, which some researchers have linked with aggression. But psychological scientist Eric Hehman of Dartmouth College and colleagues at the University of Delaware speculated that these behaviors may have more to do with social dominance than outright aggression. Hehman conducted the research while he was a graduate student at UD. (more…)

A new statistical model predicts that by 2100 the number of people older than 85 worldwide will increase more than previously estimated, and there will be fewer working-age adults to support them than previously expected. (more…)
