An international team of astronomers has detected a colossal black hole that is 12 billion times more massive than the sun—so big that it is challenging accepted cosmological thinking. Scientists discovered the enormous celestial body, which is 12.8 billion light-years from Earth, at the center of a brilliantly glowing quasar, a cloud of gas that gets superheated and gives off […]

There’s no question that our species has had a dramatic impact on the planet’s physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and the University […]

In its early days, Earth became hell. About 3.3 billion years ago, new research indicates, at least two massive asteroids 30 to 60 miles in diameter smashed into this planet, boiling the oceans and sending atmospheric temperatures soaring to an unimaginable 932 degrees Fahrenheit. Stanford University scientists have found evidence of this extreme era in a geological formation in South […]

Why do chimpanzees kill one another? For years, many studies have shown that chimps that were observed killing one another had become more aggressive only when humans encroached on their environment. But new studies have lent weight to an alternative theory: Chimpanzees are, like humans, natural-born killers who use violence as a means of expanding their territory and increasing their […]

Ocean temperatures first collected during one of the great 19th-century voyages of exploration confirm one of the consequences of climate change: humans have managed to warm even the deepest parts of the ocean. A new study in Nature Climate Change calculates that the amount of heat absorbed by the ocean has doubled in the last 18 years. A third of […]

According to a new study by Nasa, Antarctica’s Larsen B ice-shelf is on course to completely disintegrate within the next five years. Studies show that the 10,000-year-old ice shelf, after partially collapsing in 2002, is “quickly weakening.” “These are warning signs that the remnant is disintegrating,” said Ala Khazendar of Nasa’s Jet Propulsion Laboratory (JPL) in Pasadena, California. “Although it’s […]

“Colony collapse disorder” the mysterious, decade-long die-off among honeybees, is getting worse. A survey of about 5,000 beekeepers in the U.S. has found that they’ve lost about 42 percent of their colonies over just the past year. Even more alarming is the fact that honeybee deaths spiked in the summer, when bees are usually healthiest. “What we’re seeing with this […]
