If present temperature trends continue, one-sixth of the species alive today could become extinct. That's the alarming forecast of a new study in Science, a meta-analysis of 131 previous research efforts from around the world. Species in North America and Europe face the lowest risk of extinction, while those in South America are most vulnerable.
About one in six species now alive on the planet could become extinct as a result of climate change, according to a study published in Friday’s edition of the journal Science.

This small device was made by a 3D printer. What makes it amazing is that it's designed to be implanted in an infant, then grow with her until her airways are strong enough to stay open on their own. By then, the device will be absorbed by her body. Researchers call it the first known cure for the condition called tracheobronchomalacia.
Doctors ;at the University of Michigan have created the first 3-D printed device that can grow with an infant and disintegrate inside the body when no longer needed.

The adult brain that was awash in alcohol during its formative years looks different and acts differently than an adult brain that skipped the youthful binge drinking. So says a new study conducted on rats. http://lat.ms/1HPoMcn

The HPV vaccine was designed to protect against cervical cancer, a disease that has a median age at diagnosis of 48. But it doesn't take decades for the vaccine to pay off. A new study shows that girls who got Gardasil saw health benefits pretty fast -- before they graduated from high school. It reduced their risk of cervical dysplasia and (apparently) genital warts.
Years before the HPV vaccine prevents women from getting cervical cancer, it protects them against genital warts and cervical dysplasia, new research suggests.

THIS is why your kindergartener can fix your iPhone. More than one-third of parents in this survey said their infants had used smartphones or tablets before turning 1. What's more, 15% of babies used an app before their first birthday, and 24% had placed a phone call.
Have you ever been befuddled by a feature of your iPhone, only to have your 6-year-old show you how it works? A new study helps explain how this happens.

What did stegosauruses have in common with lions and peacocks? The males of the species looked a lot different than the females. A new study makes the case that the plates of their distinctive armor were 45% larger on males than on females.
When it comes to the stegosaurus, it might be very easy to tell the ladies from the gents. A new study of the dinosaurs’ ridges of fierce plates shows that males and females sported very different armor.

Scientists identify a new challenge in sending astronauts to Mars -- the exposure to cosmic radiation during the long trip could cause changes in the brain that look like dementia. That's what scientists found when they exposed mice to a simulated "space" environment with fake cosmic rays.
Many things would be difficult about conducting a manned mission to Mars, from designing a spacecraft that could make the 34-million-mile journey, to stocking and fueling it, to keeping its astronauts from getting flabby and bored.

Can you fight childhood obesity with an emoticon? Apparently so. When this green smiley face was posted next to plain nonfat milk, vegetables and other healthful options in en elementary school cafeteria, students were more likely to put them on their trays.

Why is the sun's corona so much hotter than its surface? Scientists say they've finally solved the mystery. The culprit is nanoflares, which are caused by the twisting and breaking of magnetic field lines around the sun.
One of the greatest mysteries of how stars behave has been right in our own backyard: the sun’s corona. Scientists have long wondered what heats this thin, ethereal shell of particles to roughly 300 times the temperature of the surface of the sun itself.

If you thought child abuse was bad -- and it is -- you'll want to check out this study on the long-term effects of bullying. In two countries, researchers found that kids who were bullied by their peers were more likely to have mental health problems as adults than were kids who were abused by grown-ups.
The long-term effects of being bullied by other kids are worse than being abused by an adult, new research shows.

Happy Anniversary to the Hubble Space Telescope! Its images have appeared on postage stamps, album covers and countless computer screen savers. Not to mention, it's really helped scientists understand the nature of our universe. We're looking forward to the next 25 years.
Among the pillars and valleys of a nebula 20,000 light-years from Earth, a stellar nursery of glowing gas and dust nurtures thousands of baby stars. This cosmic fireworks display comes to Earth courtesy of the Hubble Space Telescope, which celebrates its 25th anniversary in space on Friday.

Another thing to blame on your genes: The fact that mosquitoes love to bite you. A new twin study shows there is a genetic basis to either attracting or repelling mosquitoes. The degree of heritability is about the same as height, and in the same ballpark as IQ.
Are you a mosquito magnet? If so, your genes may be to blame.
