Patent trolls launched majority of U.S. patent cases in 2012

It's hip to be litigious.

In case the spat between Apple and Samsung, and myriad other tussles between tech giants weren't proof enough, comes a new study that says lawsuits filed by patent trolls last year made up the majority of patent-related complaints filed in the U.S.

The study, which was published by UC Hastings and Lex Machina this morning, analyzed about 13,000 cases spanning some 30,000 patents. It's a follow-up to last October's look at some 100 lawsuits, which found that lawsuits from patent firms were up 22 percent in the past … Read more

Heart study uses mobile tech to try to enroll 1M participants

If researchers at the University of California at San Francisco have their way, their new heart disease study won't suffer from a small sample size. Using online and mobile phone tools, they hope to get 1 million people from around the world to participate.

Launched this week, their Health eHeart Study (yes, very cute) enables participants to use their smartphones to frequently monitor heart rate, blood pressure, and pulse rate, and submit the resulting data via a secure online portal. The researchers, in turn, will use fancy algorithms to crunch that massive volume of data.

The goal? To use the super sample size to better understand -- and thus predict and prevent -- heart disease.… Read more

Researchers link mental illness with Facebook behaviors

Can social-media activity be used as a tool in psychological diagnosis? The jury's still out, but a study from researchers at the University of Missouri found a link between social anhedonia and a decrease in Facebook activity, which suggests that therapists can use patients' Facebook profiles to better understand their mental illnesses.

The study, "Social networking profile correlates of schizotypy," looked at the Facebook profiles and activities of 211 college students who were scored on their social anhedonia, perceptual aberration, and magical ideation, extraversion, and paranoia tendencies. Social anhedonia is the diminished experience of positive emotion for … Read more

Taste test: Does hot cocoa taste better from an orange cup?

I've always heard that smell plays an important role in how food tastes. I didn't expect that color could also sway the taste buds. A study published in the Journal of Sensory Studies found that the color of a cup can influence the way people taste hot chocolate.

Betina Piqueras-Fiszman, a researcher at the Polytechnic University of Valencia in Spain, and Charles Spence, a professor at the University of Oxford in England, subjected 57 participants to what may be one the tastiest science experiments ever.

The participants tasted samples of hot chocolate served in four different colors of plastic cups: white, cream, red, and orange. The sippers preferred the flavor of the beverage in orange or cream-colored cups. … Read more

Senator: Let's study violent video games -- again

Sen. Jay Rockefeller (D-WV) has introduced legislation that calls for an investigation into violent video games and their impact on children in the wake of last week's horrific Sandy Hook Elementary School shooting.

In a statement released yesterday, Rockefeller said that his legislation enlists the National Academy of Sciences to "investigate the impact of violent video games and other content on children's well-being." If the organization is given the green light, it will present its findings within 18 months to Congress, the FTC and the FCC.

"Recent court decisions demonstrate that some people still do … Read more

James Cameron's solo dive to the ocean's deepest spot

James Cameron is a man who clearly likes to collect records. Already, the famous film director has twice broken the record for highest-grossing movie of all time, first with "Titanic," and later with "Avatar." But in 2012, he went for a very different kind of mark: the deepest solo sea dive in history.

On March 25, Cameron piloted a submersible known as the Deepsea Challenger to the bottom of the Mariana Trench, fully 35,756 feet below the surface of the Pacific Ocean. He was not the first to make that dive -- Navy Lt. Don … Read more

Singles go for smartphones, while couples like tablets?

Now singles can look at what device someone is using to decide whether they're married and if it's safe to hit on them.

Singles seem to prefer smartphones while married folks go for tablets, according to a new study released today by marketing firms The Search Agency and Harris Interactive.

"Married people are often older, have more disposable income and can more easily justify superfluous pieces of technology, such as tablets," The Search Agency's marketing strategy vice president Mike Solomon said in a statement. "At the same time, baby boomers are often more tech-literate … Read more

iPads once again the top holiday gadget among kids, study says

Kids in the U.S. sure do like Apple gear, says a new study.

According to a recent poll of children ages 6 to 12 in the U.S. by research firm Nielsen, Apple's tablet once again came in first as the most-wanted gadget this holiday season, followed closely by iPods and iPhones. Of those polled, 48 percent said they wanted an iPad.

This is actually the third year in a row Apple's tablet has topped the list. Since 2010, the gadget has beat out computers, and Apple's own iPod Touch. This year's list also includes … Read more

GOP flip-flops over supporting digital copyright reforms

In an bizarre policy flip-flop, a group of more than 160 House Republicans appeared to endorse extensive digital copyright reform on Friday, then disavowed its position the next day.

The House Republican Study Committee, an influential collection of conservatives that tends to pull the House leadership to the right, published a set of recommendations that could have been penned by Larry Lessig and the Electronic Frontier Foundation: expanded fair use rights, lower penalties for "willful" infringement, and dramatically abbreviated copyright terms.

That seemed to be more evidence that Republicans had become copyright skeptics, especially since most of the … Read more
