This Is Your Brain on Nicotine

Researchers are finding strong evidence that parts of the brain are involved in gaining control over smoking and nicotine addiction, and that different areas may be important for each individual.

Two new studies examined the neural systems of people addicted to smoking and found that their brains had highly variable reactions. "One study, published online by the journal Nature Neuroscience, found that people who had a stronger brain response in certain brain regions when getting individually tailored smoking-cessation messages were more likely to quit four months later. ... The second study, published in the journal Psychological Science, also used brain imaging to watch three specific brain regions known to affect inhibition of unwanted or habitual behavior."

Horseshoe crabs are captured for their blue blood. That practice will soon be over.

The blood of horseshoe crabs is harvested on a massive scale in order to retrieve a cell critical to medical research. However, recent innovations might make this practice obsolete.

Surprising Science
  • Horseshoe crabs' blue blood is so valuable that a quart of it can be sold for $15,000.
  • This is because it contains a molecule that is crucial to the medical research community.
  • Today, however, new innovations have resulted in a synthetic substitute that may end the practice of farming horseshoe crabs for their blood.
