Could your own skin "know" what it's touching before your brain does? That's exactly what researchers at Umeå University in Sweden have been studying, and the results are interesting to say the least. What they've discovered is that neurons which branch through our skin don't just send signals to the brain they've made contact with an object, but it seems they actually process complex information about the object before surging through the spine. Only after the message has been received in the cerebral cortex region of the brain, does it become processed further.
The human face is incredibly versatile in projecting thought and emotions, including one in particular, the angry face. As a behavior that's remarkably similar despite language barriers or even entire species, the question isn't who displays anger, but why? “The expression is cross-culturally universal, and even congenitally blind children make this same face without ever having seen one,” said lead author Aaron Sell, a lecturer at the School of Criminology at Griffith University in Australia.
Genuine questions about our world may finally be answered if all goes according to plan. Using a fairly complex device called the Holometer or "holographic interferometer," scientists split a laser in two and beam them through a perpendicular path until they reach mirrors which bounce back and recombine with the beam splitter. By analyzing fluctuations or waves in the beams, researchers hope to find "holographic noise" which could probe the very nature of space-time itself.
