Internet addiction fueled by gene mutation, scientists say

Internet addiction is real, researchers out of the University of Bonn say, and its source can be explained at the molecular level.

Researchers from the school's departments of psychology and neuroscience report in the September 2012 issue of the Journal of Addiction Medicine that a simple variation on the CHRNA4 gene results in a significantly higher prevalence of Internet addiction -- and particularly in women.

"Internet addiction is not a figment of our imagination," lead author Christian Montag says in a news release. "The current data already shows that there are clear indications for genetic causes of Internet addiction... If such connections are better understood, this will also result in important indications for better therapies."… Read more

Will Apple murder the iPhone?

Apple's primary concern right now should be coming up with a new device or innovation to kill the iPhone.

That's the opinion of analyst Horace Dediu, who spoke along with Piper Jaffray's Gene Munster on a panel on the future of Apple, at the Fortune Brainstorm Tech conference in Aspen, Colo.

"We're in uncharted territory," Dediu told the room, referring to Apple's remarkable pattern of growth over the past decade or more. "(Apple) has been able to constantly create new categories and self-cannibalize." … Read more

U.S. retakes Top500 supercomputer crown

Sequoia, an IBM Blue Gene/Q supercomputer at the Lawrence Livermore National Laboratory, reached 16.32 petaflops, while previous leader K Computer trailed with 10.5 petaflops, according to the Top500 list. The list was published today at the International Supercomputing Conference in Hamburg.

The latest edition of the list, which is published twice a year, shows that Intel is slipping and IBM is recapturing lost ground, while the U.S. is back on top after losing its lead three years ago. New technologies reign, from updated IBM chips to a build of Fujitsu's novel interconnect product.

Apple TV will start slow revolution in 2013, says analyst

Apple will release a television in 2013 for between $1,500 and $2,000, but it won't instantly revolutionize the industry, says Piper Jaffray analyst Gene Munster. You have to wonder how much time it takes to trim a hedge that big.

Munster says the content offerings on an Apple-branded set might not initially be that much different than that of the currently available Apple TV set-top box, but that within five years he would expect the company to push back against the current cable and satellite TV models and move toward more DVR in the cloud and unbundled channels that consumers can pick and choose. … Read more

Sky's the limit: Analyst says Apple could be worth $1 trillion

Apple could be the first company worth $1 trillion in market capitalization as shares hit $1,000, according to Piper Jaffray analyst Gene Munster.

Somehow it's unlikely that Apple CEO Tim Cook is sending Munster any thank you notes. After all, we've seen these wild market calls before. Dow Jones Industrial Average at 25,000? Sure why not. All those dot-com stocks justified to the stratosphere in 2000. Magazine covers proclaiming bear and bull markets. You know the drill. One huge call can signal the end.

Rest assured Munster has more fundamental data backing him up. Apple is … Read more

Nifty stem-cell engineering sheds light on Parkinson's disease

Researchers at the University at Buffalo may have taken a significant step toward unraveling the way Parkinson's disease assails the human nervous system--thanks in part to a nifty bit of stem-cell engineering.

Scientists led by physiologist Jian Feng took skin cells from healthy control subjects and people with a particular type of Parkinson's disease and transformed them into a type of primordial cell--technically, an "induced pluripotent stem cell." Such iPS cells, as they're known, can be coaxed into developing as almost any type of cell in the body.

Here, they turned into brain cells. … Read more

Rumor Has It, Ep. 17: Instagram helps us care about Windows Phone

It's Tuesday again, and this time we are prepared.

Venter introduces X Prize to sequence centenarians' DNA

What does it take to make it to 100 years old? The Archon Genomics X Prize hopes to find out.

As I've researched "extreme" aging in recent years--that is, the genes and lifestyles of centenarians (100 and older) and supercentenarians (110 and older)--a common refrain I hear from my younger peers is, "I don't want to get that old. It sounds miserable."

Whether or not that's true is something most of us will never find out. The reality is that those who make it past 100 are an exceedingly rare breed of … Read more
