Neuroscience and the Stock Market

“The Fed should buy a brain scanner.” Neuroscientist Read Montague at Baylor College of Medicine looks at the brain to explain the market's boom and bust cycle.

"Why are bubbles such a persistent feature of financial history? Economists argue that these speculative frenzies are caused in part by market failures like too much liquidity or lax regulation. Cognitive psychologists, meanwhile, see bubbles as a case of pattern recognition gone awry, as people extrapolate the past into the future. In recent years, neuroscientists also have become interested in bubbles, if only because the financial manias seem to take advantage of deep-seated human flaws; the market fails only because the brain fails first. Read Montague, at Baylor College of Medicine, has spent the last few years trying to decipher the bits of brain behind our irrational exuberance. It’s microeconomics at its most microscopic."

Scientists discover how to trap mysterious dark matter

A new method promises to capture an elusive dark world particle.

Surprising Science
  • Scientists working on the Large Hadron Collider (LHC) devised a method for trapping dark matter particles.
  • Dark matter is estimated to take up 26.8% of all matter in the Universe.
  • The researchers will be able to try their approach in 2021, when the LHC goes back online.
