...Falk and the others identified seven specific features of Flo's brain that seem to be more-evolved versions of key characteristics of the much older A. africanus brain. "Over the entire cerebral cortex, there are advanced features that make it look like a very fancy brain," says Falk. "H. floresiensis was clearly there a long time, because it developed its own features...
...Overall, Flo's brain shows the global neural reorganization that's a mark of advancing intelligence. What's striking about this relative sophistication is that it developed in such a small brain case. A prime indicator of increasing human intelligence has long been thought to be increasing brain size. However, Falk says, the hobbit's skull is a bit of a mishmash of characteristics in terms of who it resembles. "Its brain sorts with africanus, yet its outside skull features look like Homo erectus," she says...
...this,” said Kate Chang, a staff member to Massachusetts congressman Michael E. Capuano. “We can be the ones to bounce back first and stronger—we’re not in debt, our political leaders are on board and we have the brain power not only in the five-college area,” Chang said. Gore’s campaign outlines the reduction of carbon in the atmosphere from its current level of 387 parts per million to below 350 parts per million. Activists at the town hall event said that...
...Unfortunately, this ability to change settings or switch channels whenever we want has a downside. Research has shown that exposure to repeated blips of information from video games and TV may rewire the brain to create shorter attention spans. Some researchers have even suggested that the rise in cases of Attention Deficit Hyperactivity Disorder may be connected to the growing screen culture...
What Causes Jet Lag? In a study in the current issue of Biology, researchers report that they've figured out the cause of jet lag: a desynchronization of the internal clocks of two groups of neurons deep in the brain. One group is associated with deep sleep, which results from fatigue; the other is linked with rapid eye movement, or REM, sleep. Although the first group of neurons can be reset in a few days, the latter can take up to a week to catch up - so, one part of the brain thinks its in Paris, while the other insists...
