The world's best supercomputers are staggeringly inefficient and energy-intensive machines and the human brain is staggering in its own right; putting a brain's information into CDs would require a skyscraper full of them and, unlike MP3s, there is no way to just create a compression algorithm.

The 86 billion neurons in our brains are connected by synapses that not only complete myriad logic circuits, they also they continuously adapt to stimuli, strengthening some connections while weakening others. We call that process learning and its rapid, highly efficient computational processes can't be matched.

Cognitive fatigue - fatigue resulting from mental work rather than from physical labor - occurs in patients suffering from multiple sclerosis (MS) also. 

A recent study investigated the neural correlates of cognitive fatigue in
multiple sclerosis
utilizing three neuroimaging approaches: functional magnetic resonance imaging (fMRI), which allows researchers to look at where in the brain activation is associated with a task or an experience; diffusion tensor imaging (DTI), which allows researchers to look at the health of the brain's white matter; and voxel-based morphometry (VBM), which allows researchers to investigate structural changes in the brain.

Despite mainstream media coverage of the 'controversy' over genetically modified foods, Americans still don't see the controversy.

The survey found that more than half (53 percent) say they know very little or nothing at all about genetically modified foods, and 25 percent say they have never heard of them. Without being prompted by survey takers, only 7 percent raised GM food labeling on their own as a concern.

NASA is going to measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt, which will give researchers a more comprehensive view of seasonal changes and provide context for measurements that will be gathered during NASA's ICESat-2 mission, which is scheduled for launch in 2016. 

The People for the Ethical Treatment of Animals (PETA) and the Humane Society of the United States (HSUS) say the United States Environmental Protection Agency (EPA) Endocrine Disruptor Screening Program is inconsistent when it comes to animal testing.

In recent years, approximately 4.4 million women in the U.S. have been diagnosed with bipolar disorder and women of childbearing age having the highest number of diagnoses. 

A new study has found that physiological changes during pregnancy reduce the effects of lamotrigine, a drug commonly prescribed for people diagnosed with bipolar disorder, making women more vulnerable to recurring episodes. The new findings will help psychiatrists and physicians prevent bipolar manic and depressive symptoms during pregnancy, which are risky for the health of the mother and her unborn child.
