Richard Dawkins used his Twitter account to ask some unanswered questions about biology that he finds fascinating, inviting others to share ideas about hypothetical life forms that may or may not have evolved. By nature, these questions can only be addressed using some degree of speculation, but I find this one particularly interesting and I will attempt to answer it. He asks: Continue reading
It’s unfair to have Morgan Freeman, with his smooth, deep voice, say it. In the trailer for the upcoming film Lucy, the actor who has played both the President and God addresses an auditorium of students and says, “It is estimated most human beings only use 10 percent of their brain’s capacity…Imagine if we could access 100 percent.” It’s hard not to believe Morgan Freeman.

For the star-studded cast who made up two panels at this year’s Kavli Prize award ceremony (available via webcast) at the World Science Festival in New York City today, special significance was attached to the death in November of the Norwegian-born Fred Kavli, the benefactor of 17 institutes in various parts of the world, including five dedicated solely to neuroscience.
Anguish grips the country with news of another horrific mass murder. From local police to the Secret Service, law enforcement worry about the “lone wolf.” These are individuals with no criminal record, feeling alienated and angry, plotting spectacular murder and violence in secret. “Experts” lament that there is no way to track lone wolf killers, but nothing could be farther from the truth.

I awoke this morning to a ferocious lightning storm. The house shook from thunderous booms. The predawn darkness blanched in blazing white flashes. Lightning is impressive; especially in contrast to the feeble bioelectricity generated by the body’s nerve cells. Or is that just an illusion? Neuroscientist Michael Persinger has done some back-of-the-envelope calculations that may surprise you.
