Just eight months ago, 6-year-old Emma Whitehead was gravely ill with leukemia and running out of options.Two rounds of chemotherapy had already failed, and a bone marrow transplant was no longer possible, The NewYorkTimes reports. So her parents opted for an experimental therapy developed at the University of Pennsylvania that aimed to enlist Emma’s own immune system in the fight […]

Mysterious plumes of gas rising more than 150 miles above the surface of Mars have left scientists confounded. On two occasions in the spring of 2012, amateur astronomers spotted a cloud developing on the surface of the Red Planet. The plumes, which spanned about 600 miles in diameter and changed shape constantly, appeared within a few hours and remained […]

For the first time, scientists have caught a glimpse of a black hole ejecting a hot “flare” of matter after devouring a star the size of our sun. The discovery was made thanks to the quick action of of scientists from John Hopkins University, who worked in conjunction with a team from the University of Oxford. Hubble fellow Sjoert van […]

Space scientists are trying to figure out how the mystery Mars rock shaped like a jelly doughnut suddenly appeared on Mars’s surface, in full view of the rover Opportunity’s camera. NASA scientists noticed the mystery Mars rock when reviewing images taken by Opportunity as it explored Endeavor Crater. One shot depicted an empty patch of ruddy ground, but the next […]

There’s something more frightening than the kid-sized vampires, witches, and skeletons who will prowl the streets this Halloween: the paint on their faces.Gov’t officials called out the FDA for its lax regulations regarding face paints, which have been found to contain traces of spooky chemicals. “When it comes to the kind of makeup our kids slather on at Halloween, lead, nickel, and cobalt do […]

“It has happened,” said Philip Bump. For the first time in human history, atmospheric carbon dioxide levels hit a daily average of 400 parts per million (ppm) last week. “There is now more carbon dioxide in the atmosphere than at any point since 3 million years ago.” Back then, global temperatures were about 7 degrees higher, the Arctic was ice-free, […]

Scientists have long puzzled over the origins of Earth’s vast oceans. Now, new data from the Rosetta spacecraft appear to have crossed one potential source off the list: comets. Rosetta has been in close orbit around comet 67P/Churyumov- Gerasimenko since August, analyzing its chemical makeup. Among the mission’s goals was to determine if the water locked in the comet’s icy […]

The species of bacteria that dominate our guts may strongly affect whether we’re thin or fat. Researchers at Washington University collected samples of gut bacteria from pairs of twins in which one was obese and the other thin. Then they transplanted the bacteria into mice. The mice that received the bacteria from the obese twins became obese; the mice that […]

Global warming hits plateau. . . What does that mean for the threat of catastrophic climate change? Why has the warming trend slowed? Climatologists aren’t sure. What they do know is that the average air temperatures at the earth’s surface have risen only about 0.2 degrees Fahrenheit since 1998—the hottest year of the 20th century—even as humanity has continued to […]

Earth got off relatively easy last week after being hit by the biggest blast of solar radiation since 2005—but we may not be so lucky next time. Last week’s coronal mass ejection, in which a solar flare whipped an arc of magnetic particles toward Earth at 4 million mph, led some airlines to reroute flights away from the poles, where […]
