A man with an unusually tiny brain manages to live an entirely normal life despite his condition, which was caused by a fluid build-up in his skull.Scans of the 44-year-old man's brain showed that a huge fluid-filled chamber called a ventricle took up most of the room in his skull, leaving little more than a thin sheet of actual brain tissue.

There are lots of things that brain cells need to survive. Add to that list microRNAs. New research from Rockefeller University shows that neurons that cannot produce microRNAs, tiny single strands of RNA that regulate the expression of genes, slowly die in a manner similar to what is seen in such human neurodegenerative disorders

Forget what your English teacher told you about how you should avoid pronouns because they are too confusing. Brain imaging shows that pronouns can in fact help the brain process information by directly pointing at previously mentioned people in "a 'virtual' brain space".

Scientists know that information travels between brain cells along hairlike extensions called axons. For the first time, researchers have found that axons don’t just transmit information – they can turn the signal up or down with the right stimulation.

Astronomers have spotted new type of explosion in space--the supernova of a star made entirely of quarks. This blast is two orders of magnitude bigger than any supernova ever recorded and has appeared in a galaxy called NGC 1260 in the constellation of Perseus. Or as arXivblog tells it: a long, long time ago, in a galaxy far, far away....

In subtle patterns of brain cells, researchers are exploring empathy -- an essential intuition that helps us understand our fellow human beings.These unusual brain circuits are mirrors in the mind that reflect the actions and intentions of others as if they were our own, new research has revealed.

Many scientists lament that money for basic research is becoming harder to obtain as governments, corporations and other big funders seek specific breakthroughs that can be applied relatively quickly. 79-year-old Norwegian-born philanthropist Fred Kavli aims to change this with what he hopes will be 21st-century versions of the Nobel Prizes.

Murray Gell-Mann is one of the largest living legends in physics. He's also been described as The Man With Five Brains, and it's no puzzle why: He was admitted to Yale at 15, got his PhD from MIT at 21, and is an international advisor on the environment. He speaks 13 languages fluently (at last count), and has expertise in such far-ranging fields a

Of all the objects in the universe, the human brain is the most complex: There are as many neurons in the brain as there are stars in the Milky Way galaxy. So it is no surprise that, despite the glow from recent advances in the science of the brain and mind, we still find ourselves squinting in the dark.

Anyone notice the large number of studies that contradict each other lately? And how about these meta-studies that have been reported in many news outlets? Looks like people are starting to differentiate between legitimate and hand-wavy studies.

The MAGIC gamma-ray telescope team has just released an eye-popping preprint (following up earlier work) describing a search for an observational hint of quantum gravity. What they've seen is that higher-energy gamma rays from an extragalactic flare arrive later than lower-energy ones. Is this because they travel through space a little bit slower,
