Astronomers are watching the astronomical equivalent of an instant replay of a spectacular outburst from the unstable, behemoth double-star system Eta Carinae, which was initially seen on Earth nearly 170 years ago. Astrophysicists affiliated with UC Santa Barbara and Las Cumbres Observatory Global ...
In the beginning was the word – yes, but where exactly? Last year, Quentin Atkinson, a cultural anthropologist at Auckland University in New Zealand, proposed that the cradle of language could be localized in the southwest of Africa. The report, which appeared in Science, one of the world's l...

The new report concluded that 7 in 10 of the more than 3,1...
Astronomers know how massive stars collapse to form small black holes a few times the mass of the Sun. However, it is not clear how supermassive black holes, which can have masses of millions or even billions of times the Sun's, form in the cores of galaxies. One idea is that supermassive black hole...
A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack. The approach potentially could improve cardiac function, minimize scar size, lead to the development of new blood vessels – and avoid the risk of tissue...
Extreme summer temperatures are already occurring more frequently in the United States, and will become normal by mid-century if the world continues on a business as usual schedule of emitting greenhouse gases.
Groundwater in aquifers on the East Coast and in the Central U.S. has the highest risk of contamination from radium, a naturally occurring radioactive element and known carcinogen.
Stress levels of unemployed people are linked more to their surroundings than their age, gender, disposable income, and degree of deprivation, a study shows.
A study from North Carolina State University shows that Toyota's safety-related recalls that began in 2009 made little to no impact on how consumers perceived the brand.
Half of the young adult Latino men and women responding to a survey in rural Oregon acknowledge not using regular effective contraception – despite expressing a desire to avoid pregnancy, according to a new Oregon State University study.
Four new species of miniaturized lizards have been identified in Madagascar. These lizards, just tens of millimeters from head to tail and in some cases small enough to stand on the head of a match, rank among the smallest reptiles in the world. The full report can be found in the Feb. 15 issue of t...
