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.

The rise of anti-scientific thinking and conspiracy is a concerning trend.
- Fifty years later after one of the greatest achievements of mankind, there's a growing number of moon landing deniers. They are part of a larger trend of anti-scientific thinking.
- Climate change, anti-vaccination and other assorted conspiratorial mindsets are a detriment and show a tangible impediment to fostering real progress or societal change.
- All of these separate anti-scientific beliefs share a troubling root of intellectual dishonesty and ignorance.
The history of the Geneva Conventions tells us how the international community draws the line on brutality.
- Henry Dunant's work led to the Red Cross and conventions on treating prisoners humanely.
- Four Geneva Conventions defined the rules for prisoners of war, torture, naval and medical personnel and more.
- Amendments to the agreements reflect the modern world but have not been ratified by all countries.
