Another electrode was strapped to my left arm, and both were connected by a series of wires to a small black box containing some electronics and a couple of 9-volt batteries. Transcranial direct current stimulation, or tDCS, is a noninvasive form of brain stimulation that involves passing a current between electrodes on the scalp.

This learning by teaching paradigm, they say, could engage unmotivated students as well as boost their self-confidence. The prototype system, called CoWriter, was developed by researchers at the Swiss Federal Institute of Technology (EPFL) in Lausanne. A humanoid robot, designed to be likeable and interact with humans, is presented with a word that the child spells out in plastic letters. ...

Small Minority Have No Health Problems If you're in perfect health, you're in the minority: Less than 5 percent of people worldwide had no health problems in 2013, a new study finds. Researchers analyzed information on about 300 diseases and conditions — everything from acne and PMS to chronic conditions such as heart disease and diabetes — and more than 2,300 disease-related consequences, in people in 188 countries. Overall, just 4.3 percent of people had no health problems, the researchers found.

"We could use a lot less blood [than traditional tests]," said Tomasz Kula, one of the co-authors of the new research and a graduate student at Harvard Medical School. The VirScan test uses these engineered viruses to look for antibodies to each of these viruses in a sample of a person's blood.

The FBI's surveillance planes are supposedly used only to support the agency's operations on the ground, the AP reports. The FBI has been using small aircraft to support its ground operations (for example, tracking suspects) since at least the 1980s, according to AP's report, which also states that the planes are owned and operated by front companies.
