How lasers can switch off cocaine addiction

Researchers who shined a laser light in a certain region of the brain -- stimulating the area associated with decision-making and impulse control -- were able to zap what they call "cocaine seeking" behaviors in addicts.

And while their work was on rats, their hope is that a similar technique called transcranial magnetic stimulation (TMS, currently used to improve symptoms of depression) will work on humans as well.… Read more

Biofeedback video game helps kids control anger

Researchers at Boston Children's Hospital had the bright idea that, since kids with anger-control problems tend to resist psychotherapy but enjoy video games, the researchers should develop a game that sneakily helps kids practice emotion-control skills -- and in the process perhaps reduces the need for medication.

The game, called RAGE Control (short for Regulate and Gain Emotional Control), employs a finger heart rate monitor; users with elevated heart rates actually lose the ability to shoot enemy spaceships. Researchers say the idea is to teach kids to better control their emotional responses -- and specifically to reduce outbursts of … Read more

Instacart aims to be the Amazon Prime of grocery delivery

In cities like San Francisco, shoppers have a number of ways to order groceries online for home delivery. But one startup there thinks that by mimicking Amazon's Prime service and selling subscriptions for unlimited free delivery, it can change customers' behavior and generate a great deal more orders.

Instacart, a current Y Combinator company that came out of stealth mode earlier this month, has been letting users in an invite-only beta buy groceries with quick delivery through its iPhone app for some time. One-hour delivery costs $10, while three-hour delivery runs $4.

Now, CNET has learned, the company has … Read more

Behavioral data tracking rising dramatically (Q&A)

Web sites are increasingly targeting ads at visitors based on behavioral data collected via cookies and other tracking techniques behind the scenes. This riles privacy advocates and many consumers, but there's no question it will become even more widespread.

Since November 2010, behavioral tracking has increased 400 percent, according to a new study from Krux, a firm that helps Web sites manage customer data. The average visit to a Web site in December triggered 56 instances of data collection, up from 10 instances in Nov. 2010, the company found after crawling pages on the 50 most-visited sites measured by … Read more

Airtime curtails privacy for the sake of safety

Now that the oohs and ahhs of Airtime's launch this week have settled, it's time to look at the nitty gritty of this new browser-based video chat service. One of the company's policies involve user privacy.

The way Airtime works is by using Facebook as its log-in platform. At its basic level, Airtime allows simple video chat with users' Facebook friends, but take it up a notch and it lets people chat with strangers that have common interests.

So, as a way to keep its users safe, the service takes random secret photos of video conversations between … Read more

The case for getting grandma to play World of Warcraft

The online video game World of Warcraft is in the news again, this time for its potential to help boost certain cognitive skills--specifically spatial ability and focused attention--in older adults.

Researchers at North Carolina State University's Gains Through Gaming Lab tested the cognitive functions of 39 60- to 77-year-olds and then broke the study's participants into an experimental group, which played the MMORPG for 14 hours over a two-week period, and a control group, which did not play WoW at all.

It turns out that the adults who played WoW for two weeks improved their baseline scores, with … Read more

Chrome to support Do Not Track privacy feature

Google has agreed to build support for Do Not Track into Chrome so its Web browser can tell Web sites when people don't want advertisers scrutinizing their behavior.

The Do Not Track technology modifies communications between browsers and servers so people can signal that they don't want their browsing behavior to become the basis for ad targeting.

Mozilla developed Do Not Track and built it into its Firefox Web browser. Microsoft followed suit not long after with Internet Explorer, Apple has enabled it as an option for developers in Safari 5.1, and Opera is building it into the forthcoming Opera 12. … Read more

Got chronic pain? Your phone might help heal you

Do you hurt everywhere? Can't find any lasting solutions? Before you start popping pills, consider a little talk therapy--by telephone.

Chronic widespread pain, a condition called fibromyalgia, affects as many as 1 in 10 Americans, and is notoriously tricky (and expensive) to manage.

In the first six months following diagnosis, it costs on average $3,481 for medications, consultations, tests, and emergency room visits, according to researchers at the University of Aberdeen and the University of Manchester, both in the U.K.

So the researchers decided to investigate two less expensive alternatives: exercise and cognitive behavioral therapy (by phone).… Read more

Has content become advertising for advertising?

Since the advent of the Web, online publishers have had to create unique content to attract premium ad rates. Over the past few years, however, a flood of subpar content has seemingly taken over the Web, driven by high-growth sites such as Demand Media and the AOL-owned Huffington Post.

These types of sites have enjoyed surging traffic by creating relatively simplistic content, repurposing and "aggregating" premium content, and gaming Google's search algorithm. But this strategy faces a growing backlash and as a result may have hit its natural ceiling, and that could create opportunities for new online-media … Read more

Millions of tweets reveal global mood trends

It may not be terribly surprising that many of us find our moods dipping over the course of the day, and that by nightfall we light up again. Or that our moods are perkiest on weekends, regardless of which days our weekends fall on (i.e., Fridays and Saturdays in the United Arab Emirates).

What's of note, according to an analysis of 2.4 million tweets in 84 countries by researchers out of Cornell, is that these mood trends hold steady across cultures and borders, hinting at some sort of deeper trend whose basis is in being human, not … Read more
