We humans spend roughly one-third of our lives asleep but researchers don't know why. 

Science magazine listed the function of sleep is one of the 125 greatest unsolved mysteries in science and we've seen theories range from brain 'maintenance', including memory consolidation and pruning, to reversing damage from oxidative stress suffered while awake, to promoting longevity. None of these theories are well established, and many are mutually exclusive. 
Next year begins one of the largest and most important scientific experiments in history; the initial attempts at the National Ignition Facility (NIF) to produce the world's first controlled nuclear fusion reaction and tame the energy source of the sun.

That would mean a limitless new source of energy for homes, factories, and businesses.
Premier League clubs who have long-term managers are more successful than those who change their managers on a frequent basis, say business school researchers.

Because there's nothing sports clubs want more than advice from  academics who examine past trends and draw conclusions  based on the fact that elite clubs fire people less.
The lowly appendix used to get no respect and was simply regarded as a useless evolutionary artifact but two years ago researchers at Duke University Medical Center proposed that it actually serves a critical function as a safe haven where good bacteria could hang out until they were needed to repopulate the gut, like after a nasty case of diarrhea. 

Now a group writing in the Journal of Evolutionary Biology claim something even more aggressive; that Charles Darwin was wrong and the appendix is a whole lot more than an evolutionary remnant. Not only does it appear in nature much more frequently than previously acknowledged, but it has been around much longer than anyone had suspected. 

Annoyed that your child schleps home 35 lbs. of books and settles in for 3 hours of homework per night?   Dreaming of an ancient time when teachers teached during the day?

Nope.  Contrary to common belief, parents are okay with the homework load,  according to a new study from University of Nebraska-Lincoln researchers.

Students are spending considerable time doing homework but parents are generally supportive of homework practices, their study says. They're also involved in homework, usually in minimal but supportive ways, said Ken Kiewra, UNL professor of educational psychology and an expert on learning strategies, homework and study methods.

Researchers at Virginia Tech believe they have solved the controversy over how the oldest complex life forms, which lived more than 540 million years ago, ate.    Osmosis, they say.

The researchers studied two groups of modular Ediacara organisms, the fern-shaped rangeomorphs and the air mattress-shaped erniettomorphs. These macroscopic organisms, typically several inches in size, absorbed nutrients through their outer membrane, much like modern microscopic bacteria.  The rangeomorphs had a repeatedly branching system like fern leaves and the erniettomorphs had a folded surface like an inflated air mattress to make tubular modules.
