There’s a strange new brute on the celestial block—the middleweight black hole, a new study says. After nearly three years of spying a superbright object nearly 300 million light-years away, astronomers with NASA’s Chandra X-ray Observatory and SWIFT telescope recently announced the discovery of HLX-1, the first representative of a new type of black hole….
Some 460 light-years away in the constellation Centaurus, a thick disk of dust swirled around a young star named TYC 8241 2652 1, where rocky planets like our own were arising. Then, in less than 2 years, the disk just vanished. That’s the unprecedented observation astronomers report in a new study, out today. Even more…
Being the top dog – or, in this case, the top gelada monkey – is even better if the alpha male is willing to concede at times to subordinates, according to a study by researchers from the University of Pennsylvania, the University of Michigan and Duke University. Alpha male geladas who allowed subordinate competitors into…
Inequality is growing in the United States, and social mobility is slowing. A study by the Pew Charitable Trusts found that 62 percent of Americans raised in the top one-fifth of the income scale stay in the top two-fifths; 65 percent born in the bottom fifth stay in the bottom two-fifths. Education, long praised as…
A Kansas State University-led quantum mechanics study has discovered a new bound state in atoms that may help scientists better understand matter and its composition. The yet-unnamed bound state, which the physicists simply refer to as “our state” in their study, applies to three identical atoms loosely bound together — a behavior called three-body bound…
A giant string of invisible dark matter has been discovered across the universe between a pair of galaxy clusters. The filament forms a bridge between two huge clusters called Abell 222 and Abell 223, which lie 2.7 billion light-years away. The universe is thought to be filled with such strings of dark matter, a mysterious…
Humans started causing climate change long before the Industrial Revolution and the beginning of the fossil fuel era. A new study shows that the echoes of the earliest human-caused carbon emissions are still present in our atmosphere. In fact, preindustrial carbon emissions, caused by deforestation as the world’s population grew, were responsible for 9% of…
As nonconventional medical treatments become increasingly mainstream, we take a look at the science behind some of the most popular.
Health apps are hot, but until now the field has been unregulated. It is hard to know which apps actually live up to their claims or provide accurate information. Now, the FDA is laying down the law, releasing a first draft of guidelines that require developers making medical claims to apply for FDA approval. But app developers are bristling.
Scientists working at the world’s biggest atom smasher near Geneva have announced the discovery of a new subatomic particle that looks remarkably like the long-sought Higgs boson. Sometimes called the “God particle” because its existence is fundamental to the creation of the universe, the hunt for the Higgs involved thousands of scientists from all over…
