The Neuroscience of Rick Perry's Brain Freeze

Despite the media attention drawn by Rick Perry's brain freeze in the last Republican debates, scientists say it is not evidence of an intellectual dificiency or mental problem.

What's the Latest Development?

Unless you've had your head under a rock, you know about Rick Perry's brain freeze during the last Republican debates. At one point in the evening, the Texas governor could not remember, for the life of him, which three federal agencies he would eliminate. A media firestorm subsequently ensued. The coverage was certainly overblown but should Perry's forgetfulness count against him in the presidential race? Not necessarily, say neurologists—even fiercely Democratic ones.

What's the Big Idea?

Sometimes the brain works correctly, sometimes it doesn't. When we cannot remember simple information, such as was Perry's case, neuroscientists refer to the phenomenon as "retrieval failure". It turns out that the brain's language center is located far from its memory banks. When pressure builds, such as during a nationally televised debate, sometimes the connection fails. Neuroscientists say brain freezes are happening more often since, thanks to the information revolution, we demand more from our brains than ever before.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.

Project 100,000: The Vietnam War's cruel and deadly experiment

Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?

  • During the Vietnam War, Robert McNamara began a program called Project 100,000.
  • The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
