Mysterious Brain Connections

Scientists were recently surprised to find that brains missing a corpus callosum, which links the two hemispheres of the brain, were still able to communicate quite effectively. But how?

What's the Latest Development?


Researchers were recently surprised to find that brains missing a corpus callosum, which links the two hemispheres of the brain, were able to communicate information between the two halves quite effectively. Is the brain capable of using electromagnetic waves to transfer information between hemispheres? Johnjoe McFadden of the School of Biomedical and Life Sciences at the University of Surrey thinks so. He has recently proposed an electromagnetic consciousness theory of the brain. 

What's the Big Idea?

Human brains without a corpus callosum are relatively rare, occurring approximately once every 4,000 live births. Composed of 200 million axons, it is the brain's largest fiber bundle. Scientists do not currently understand how information is passed from one hemisphere to another without the specialized fibers but they believe the phenomenon may give insight into clinical conditions including autism and schizophrenia. About a third of individuals missing the corpus callosum are also autistic.

We are heading for a New Cretaceous, not for a new normal

The climate change we're witnessing is more dramatic than we might think.

Surprising Science

A lazy buzz phrase – 'Is this the new normal?' – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it's worse than that – we're on the road to even more frequent, more extreme events than we saw this year.

New study reveals what time we burn the most calories

Once again, our circadian rhythm points the way.

Surprising Science
  • Seven individuals were locked inside a windowless, internetless room for 37 days.
  • While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
  • Morning time again shown not to be the best time to eat.
