Watch a brain surgery over Twitter, Instagram, and Vine

UCLA Health isn't the first hospital to live-tweet a brain surgery, but it may be the first to employ 6-second video medium Vine as part of the proceedings. Surgeons on Thursday implanted a brain pacemaker to counteract the effects of Parkinson's disease in a patient and sent out Twitter updates using both Instagram and Vine.

The procedure has generated such memorable tweets as "Removing the skin and drilling through the skull for electrode placement." and "Electrode is prepared for implantation. Patient is being woken up at this time."

Scientists say they know you better than you do

Do you intend to be nice to your co-workers today? Do you intend to spend a little longer in the shower so that your personal crevices are spotless? Do you intend to write that friend request to Mark Zuckerberg and keep your list of friends private?

Well, a group of scientists at UCLA would like to thank you for words, but prefers to scan your brains to prove to you what you really intend to do.

If this all sounds a little macabre, then you clearly don't intend to follow science's inexorable path. According to Reuters, a team … Read more

Quitting smoking, one text at a time (podcast)

University of Oregon Assistant Professor of Psychology Elliot Berkman recently completed a study for his University of California at Los Angeles doctoral dissertation on smoking cessation.

Like a lot of researchers before him, Berkman asked respondents whether they had smoked--and what mood they were in, when they lit up--in an attempt to better understand compliance with smoking-cessation programs. But the difference between Berkman's study and previous ones is that he was able to repeat the question every two hours by interacting with subjects via text messaging, rather than talking with them on the phone or in person, or having … Read more

Move over pinochle, Web surfing stimulates aging brains

The University of California at Los Angeles this week gave us the perfect antidote to Nick Carr's musings in The Atlantic about how the Internet is turning us into multitasking scatterbrains with diminishing attention spans.

A group of scientists found that searching the Internet doesn't make computer-savvy, middle-aged and older adults stupid. It actually triggers key centers in the brain that control decision making and complex reasoning. In other words, we might not have to resort to word puzzles and pinochle to fend off senility.

The study, reportedly the first of its kind to assess the impact of … Read more

Self-healing artificial muscle can charge an iPhone

An artificial muscle that can heal itself and recharge an iPod at the same time? Sounds ludicrous, but researchers at the University of California at Los Angeles have developed an electricity-generating muscle that might one day be to used to create walking robots or advanced prosthetics, according to Discovery News.

Qibing Pei, a scientist at UCLA and author of the research that appeared in the January edition of Advanced Materials, said his team developed a lifelike artificial muscle by using carbon nanotubes as electrodes. Unlike other artificial muscles made with metal-based films, this muscle can expand more than 200 percent … Read more
