Yale University researchers used brain scans to "read" and reconstruct the faces that individuals were picturing in their minds' eye. The scientists ran fMRI scans on six people as they looked at 300 different faces. Those scans enabled the creation of a database of facial features tied to specific brain response patterns. Then the subjects were shown faces they hadn't seen before. Based on the new fMRI data, a computer was able to generate good approximations of the face the subject was viewing.
“It is a form of mind reading,” said Marvin Chun, Yale professor of psychology, cognitive science and neurobiology who led the study.
The research will be published in the science journal NeuroImage, and an uncorrected proof is available here (only the abstract is free).

Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
