An international team of astronomers, including from the University of Cambridge, discovered the massive object when trawling through data from the European Space Agency’s Gaia satellite. The object, named Antlia 2 (or Ant 2), has avoided detection until now thanks to its extremely low density as well as a perfectly chosen hiding place, behind the ...
Astronomers have found what could be one of the universe’s oldest stars, a body almost entirely made of materials spewed from the Big Bang. The discovery of this approximately 13.5 billion-year-old tiny star means more stars with very low mass and very low metal content are likely out there — perhaps even the universe’s very ...
A new national study out of Ohio State University shows that people whose mothers had more romantic partners — married or cohabiting — often follow the same path. Results suggest that mothers may pass on personality traits and relationship skills that make their children more or less likely to form stable relationships. Claire Kamp Dush, ...
The brain changes of teenage girls who engage in serious forms of self-harm, including cutting, show features similar to those seen in adults with borderline personality disorder, a severe and hard-to-treat mental illness, a new study has found. Reduced brain volumes seen in these girls confirms biological — and not just behavioral — changes and ...
Chemical clues in waters near Marcellus Shale gas wells in rural Pennsylvania can identify new drilling-related sources of methane contamination, according to scientists. The findings provide a new tool for distinguishing potential environmental impacts of shale drilling from pre-existing methane levels commonly found in Pennsylvania waterways, the researchers said. Scientists also found that methane contamination ...
Scientists have discovered that CO2-consuming bacteria in the deepest parts of the seafloor could be turning themselves into an additional food source for other deep-sea life. Bacteria living 4000m below the ocean surface in the Clarion-Clipperton Fracture Zone (CCFZ) are consuming carbon dioxide and turning it into biomass, a new study shows. Until now, scientists ...
In a new study, researchers with NASA, the University of Chicago, and the Potsdam Institute for Climate Impact Research added data on when each specific region plants and harvests its crops — and found it was the single most effective way to improve crop loss simulations. Droughts or heat waves have consequences that spread beyond ...
In an analysis of eight case studies from around the world — from foragers in Australia to mangrove fishers in Ecuador — researchers found that people can successfully sustainably share resources under certain conditions. Thus, there is no “tragedy” in the “tragedy of the commons,” according to a new analysis that challenges a widely accepted ...
Powerful storms that cause extreme weather conditions — such as flooding across Europe and North America, with the potential to wreak social and economic havoc — could increase threefold by the end of the 21st century due to climate change. Pioneering new research, led by Dr. Matt Hawcroft from the University of Exeter, has shown new and ...
Schizophrenia, a brain disorder that produces hallucinations, delusions, and cognitive impairments, usually strikes during adolescence or young adulthood. While some signs can suggest that a person is at high risk for developing the disorder, there is no way to definitively diagnose it until the first psychotic episode occurs. MIT neuroscientists working with researchers at Beth ...
