The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean crust that's now exposed on land in Australia. And that could have major implications on the... Continue Reading →
Blown by fast winds from a hot, massive star, this cosmic bubble is much larger than the dolphin it appears to be. Cataloged as Sharpless 2-308 it lies some 5,200 light-years away toward the constellation of the Big Dog (Canis Major) and... Continue Reading →
Rats on a high sugar diet during pregnancy have altered levels of sex steroid hormones (e.g. progesterone) and dopamine in their brains, which may lead to behavioural changes that can affect care of offspring and motivation, as well as increasing... Continue Reading →
University students and researchers working on a NASA mission orbiting a near-Earth asteroid have made an unexpected detection of a phenomenon 30 thousand light years away. Last fall, the student-built Regolith X-Ray Imaging Spectrometer (REXIS) onboard NASA’s OSIRIS-REx spacecraft detected... Continue Reading →
Oxytocin, a brain peptide that is widely known for its role in love and bonding, may hold potential for helping individuals overcome alcohol addiction. In a collaborative study with the National Institute on Drug Abuse (NIDA), scientists at Scripps Research... Continue Reading →
In 46 BC Julius Caesar reformed the calendar system. Based on advice by astronomer Sosigenes of Alexandria, the Julian calendar included one leap day every four years to account for the fact that an Earth year is slightly more than 365 days long.... Continue Reading →
