The geographic origins of the metals in Scandinavian mixed-metal artifacts reveal a crucial dependency on British and continental European trading sources during the beginnings of the Nordic Bronze Age, according to a study published July 24, 2019 in the open-access journal PLOS ONEby Heide W. Nørgaard from Aarhus University, Denmark, and colleagues. 2000-1700BC marks the earliest … Read more
Almost one in five adults in the U.S. lives with a mental illness. That statistic is similar worldwide, with an estimated 450 million people currently dealing with a mental or neurological disorder. Of those, only about a third seek treatment. Interacting with nature is starting to be recognized as one way to improve mental health. … Read more
About a dozen megadroughts struck the American Southwest during the 9th through the 15th centuries, but then they mysteriously ceased around the year 1600. What caused this clustering of megadroughts – that is, severe droughts that last for decades – and why do they happen at all? If scientists can understand why megadroughts happened in … Read more
Keven Walgamott had a good “feeling” about picking up the egg without crushing it. What seems simple for nearly everyone else can be more of a Herculean task for Walgamott, who lost his left hand and part of his arm in an electrical accident 17 years ago. But he was testing out the prototype of … Read more
A new reconstruction of global average surface temperature change over the past 2,000 years has identified the main causes for decade-scale climate changes. The analysis suggests that Earth’s current warming rate, caused by human greenhouse gas emissions, is higher than any warming rate observed previously. The researchers also found that airborne particles from volcanic eruptions … Read more
Observations made with a new instrument developed for use at the 2.1-meter (84-inch) telescope at the National Science Foundation’s Kitt Peak National Observatory have led to the discovery of the fastest eclipsing white dwarf binary yet known. Clocking in with an orbital period of only 6.91 minutes, the rapidly orbiting stars are expected to be … Read more
‘One of the mysteries of high-superconductors is the possibility of being inhomogeneous. This means that the density of the pairs causing the superconductivity changes over space’, says physicist Milan Allan of LION, ‘we proved that, indeed, very inhomogeneous superconductors exist, by imaging them for the first time.’ The discovery netted Doohee Cho, Koen Bastiaans, Damianos … Read more
The fact that millions of North American monarch butterflies fly thousands of miles each fall and somehow manage to find the same overwintering sites in central Mexican forests and along the California coast, year after year, is pretty mind-blowing. Once they get there, monarchs spend several months in diapause, a hormonally controlled state of dormancy … Read more
Levels of atmospheric carbon dioxide (CO2) are rising, which experts predict could produce more droughts and hotter temperatures. Although these weather changes would negatively impact many plants’ growth, the increased CO2 availability might actually be advantageous because plants use the greenhouse gas to make food by photosynthesis. Now, researchers reporting in ACS’ Journal of Agricultural and Food … Read more
Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other. A new study reveals that American robins that preferentially use one eye significantly more than the other when looking at their own clutch of eggs are also more likely to detect, and reject, a foreign egg … Read more
