Georgia Tech project ensures 'what you see is what you send'

Researchers at Georgia Tech have developed a prototype software called Gyrus, which takes extra steps to prevent malware from sending spam emails and instant messages. The software captures user intent and interactions with an application, verifying that the resulting output can be mapped back to the user's intention.

Study uncovers why almost winning is just as good for some gamblers

A new study found that gamblers' brains exhibit similar increases in theta activity to wins and near-misses, particularly in the insula and orbitofrontal cortex. This response is associated with gambling severity and susceptibility to problem gambling. The research suggests that brain responses to near-misses resemble those to actual w...
