Are Security Scanners Safe?

Scientists still dont know whether radiation scanners are completely safe to use on humans. This is despite months of public debate between the White House, the U.S. Food and Drug Administration, and independent scientists. Full-body scanners have been installed at many U.S. airports. The machines use either low-energy, millimeter wavelength radiation, which is harmless, or X-rays, which can potentially be hazardous. X-rays can ionize atoms or molecules, which can lead to cancerous changes in cells. In April, four scientists at the University of California, San Francisco, wrote a letter to the White House warning that the government may have underestimated the dosage of ionizing radiation delivered to a person's skin from a backscatter machine by one or two orders of magnitude.

Gesturing at Your TV Isn't Ready for Prime Time

The Microsoft Kinect is a sensor that works with the Xbox 360 game console.  A player controls the $150 device with voice and gestures; there's no need to hold any sort of controller or wear any special gloves or clothing. Microsoft's chief research and strategy officer, Craig Mundie, described the Kinect as a preview of what's to come for the future consules. Instead of thinking about controllers, keyboards, and other "application-specific prosthetics," Mundie said, people could focus on the task at hand, making software much more appealing and easy to use.

But while using the Kinect for gaming is a fun and interesting experience, the device also illustrates that natural user interfaces have a long way to go before they could be suited to most everyday applications.
The Kinect uses both software and hardware to pick up a person's position, motions, and voice. To measure position, it emits an infrared beam and measures how long that light takes to bounce back from objects it encounters. Four microphones can receive voice commands, and software filters out background noise and even conversation from other people in the room.
Since all these systems need to be calibrated, setting up the Kinect takes some time. After you connect the sensor to an Xbox 360 and position it near the center line of a television, the Kinect's motors automatically adjust its angle so that it can get a complete picture of the user.

Tracking the Brain's Ability to Bluff

In a study published today, Montague and collaborators found that people take one of three strategies when playing a simple economics game, and that specific parts of the brain seem to be more active in people who choose to bluff. A second paper published last month shows how the strategies chosen by healthy people playing a similar game change depending on the mental status of their opponent. Researchers ultimately hope to create an automated version of this approach and use it to diagnose disease. The strategists' approach required the greatest mentalizing trying to get into the mind of the other player.  But the reality was the opposite; they suggested relatively high prices when the actual value was low, likely stopping that sale. But they surmised that this would increase their credibility in the other rounds of the game; thus, when the private value was high, they could give low suggested prices. "Bluffing is a specific feature of theory of mind," explains Montague. "It touches on the capacity to model other people; included in your model of me is your model of my model of you." He notes that while none of the groups had significant differences in IQ, having an above-average IQ was necessary to be a strategist.
