É mais que sabido que alguns humanos "comem" tudo o o que mexa... E até mesmo o que não mexa.

WIN!

Breakthrough Could Enable Others to Watch Your Dreams and Memories

Scientists at the University of California, Berkeley, have reconstructed the internal “movie” that plays in a person’s head. To re-create dynamic visual experiences, they used functional magnetic resonance imaging (fMRI) to measure the brain activity of volunteers (the other members of the research team) as they watched short movie clips (left panel in the video below). A computational model crunched the fMRI data to reproduce the images, as shown in the right panel.



The team, led by Shinji Nishimoto and Jack Gallant, say that the technology is decades away from enabling people to read others’ thoughts and intentions. It could become a powerful tool to communicate with people who cannot verbalize, such as stroke victim and coma patients. This visual image reconstruction study appears in the September 22 Current Biology.

The Benefits of Being Promiscuous

Biologists have long wondered why some female animals bother to play the field. With males, spreading one's sperm as far and wide as possible makes sense, as they sire more offspring that way. For the female, however, extra sex takes a toll on her body, potentially reducing her life span. Yet it doesn't expand her chances of spreading her genes around. Researchers have now shown that promiscuity in the fairer sex has its benefits. By mating multiple times, females can compensate for the downsides of inbreeding. And that's why promiscuity may evolve in small populations.
