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.

This looks like the truly final nail in the coffin on supposed link between vaccines and autism. Even among kids who were known to be at risk for ASD, those who got immunized against MMR were no more likely to be diagnosed with autism than those who weren't. 
At least a dozen major studies have found that early childhood vaccines do not cause autism. But one possibility remained: that immunizations could cause autism ;in a small group of children who were already primed to develop the disorder.

Dr. Oz is back in the hot seat. This time a group of 10 doctors has sent a letter to his academic employer, Columbia University, asking them to cut ties with the man who touts dubious weight-loss remedies on TV. As studies have shown, much -- if not most -- of what is said on his TV show is not backed by medical evidence. That may be fine for TV, but not for Columbia, the letter says. Oz will devote a show to the issue in the middle of the week, probably on Thursday.

Your smartphone is a camera, a calculator, a flashlight and a pedometer. Scientists believe it could be part of an earthquake early-warning system too. The GPS sensors built into most smartphones are sensitive enough to detect the earliest signs of quakes that are magnitude 7 and stronger. Scientists are working on a way to link them together into a seismic-detection network.

Promising results from a clinical trial of a liquid form of medical marijuana. It reduced seizures in kids and young adults with bad cases of epilepsy by more than 50%. The full study will be presented at the American Academy of Neurology annual meeting.
In a group of children and young adults with the most intractable forms of epilepsy, a liquid form of marijuana called cannabidiol reduced seizures by more than 50% without causing the drug's usual "high," researchers said.

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.

When it comes to finding breast cancer in women with no sign of the disease, more mammograms aren't necessarily better. So says the U.S. Preventive Services Task Force, the government panel that made waves in 2009 for saying most women only need to a mammogram once every two years, and mainly between the ages of 50 and 74. They have stuck with their controversial advice in their latest recommendations, released in draft form on Monday.
Despite years of controversy over the best way to screen women for breast cancer , an expert panel convened by the federal government is standing by its controversial recommendation that most women should get mammograms only once every two years, and that the tests need not begin until the age of 50.

Here's an unconventional approach to fighting hair loss -- plucking out the hairs you have left. Stem cell experts demonstrate that pulling out hairs in a specific pattern prompts the body to swing into action to replace them -- and then some.
Frustrated by hair loss? New research suggests a peculiar, and slightly painful, solution to the ancient condition of baldness: Yank out whatever hair you have left.

Yet another study finds a link between the number of minutes of drinking kids watch in movies and the likelihood that they will drink alcohol too. The more minutes watched, the greater the risk of binge-drinking and other alcohol-related problems. The authors of the latest study say movie ratings groups like the MPAA should slap an R on any movie that depicts drinking.
Should a movie that depicts any type of drinking automatically earn an R rating from the Motion Picture Assn. of America? The authors of a new study argue that the answer should be yes – and that this would make teenagers less likely to binge-drink or use alcohol in other risky ways.
