Surprise, surprise — Male and female brains are wired differently!
A new study finds that, in men, neural fiber pathways run back and forth within each hemisphere, while in women they tend to zig-zag between the left, or “logical,” and right, or “creative,” sides of the brain.
"Acknowledging brain effects by gender does not mean these are immutable, permanent determinants of behavior, but rather they may play a part within a multitude of factors and certainly can be shaped by social and environmental influences."
A husband-and-wife team of paleobiologists have discovered the first evidence of a new species of “big cat,” one they say appears to be the oldest ever found by a “wide margin.”
"The new fossil also solves a geological mystery. Previously, using DNA analysis of all living big cats and mapping the the fossils excavated from various sites around the world, researchers had determined it was most likely that their common ancestor had lived in Asia. The oldest known specimens, however, were found in Africa. The new species provides the first direct evidence that central Asia was indeed the big cats’ ancestral home, at least as far back as the current fossil record currently goes."
MIT Invents Shape-Shifting Display You Can Reach Through And Touch
In an age where flat screens are generally preferred over tactile interaction, one MIT project team plans to change the way we interact digitally. In the same vein as gestural interaction, the team is developing an interface which is somewhat self-aware, able to form and reform based on inputs from the user. Imagine offering a digital handshake after sealing a deal. Instead of watching something on a screen, you’d literally grasp a “hand.” Creepy sci-fi, or just a glimpse of what’s to come?
"Ten years ago, we had people at Media Lab working on gestural interactions, and now they’re everywhere, from the Microsoft Kinect to the Nintendo Wiimote," says Follmer. "Whatever it ends up looking like, the UI of the future won’t be made of just pixels, but time and form as well. And that future is only five or ten years away. It’s time for designers to start thinking about what that means now."
While investigating whether intelligence might serve as a marker of brain health, researchers from Duke University discovered a link between wider retinal venules and lower IQ scores — a possible indication of a connection between blood vessels in the retina and cognitive function.
"The findings indicate that retinal venular caliber may be an indicator of neuropsychological health years before the onset of dementing diseases and suggest that digital retinal imaging may be a useful investigative tool for psychological science."
A new theory suggests an evolutionary-driven fear of snakes is a major reason humans and other primates have developed such precise vision.
“Our findings are unique in providing neuroscientific evidence in support of the Snake Detection Theory, which posits that the threat of snakes strongly influenced the evolution of the primate brain. This finding may have great impact on our understanding of the evolution of primates.”
