Twenty years ago, when brain imaging made it possible for researchers to study the minds of violent criminals and compare them to the brain imaging of "normal" people, a whole new field of research — neurocriminology — opened up.
Adrian Raine was the first person to conduct a brain imaging study on murderers and has since continued to study the brains of violent criminals and psychopaths. His research has convinced him that while there is a social and environmental element to violent behavior, there's another side of the coin, and that side is biology.
If only there was an Oscar for "Smallest Movie," a group of IBM nanophysicists would be a shoo-in with their new one-minute stop-motion video starring 130 atoms.
A Boy and His Atom, which debuts Wednesday, has already been certified by the Guinness folks as the "world's smallest movie."
While it isn't exactly the most complicated story line — the nearly monochrome video features a boy, appropriately named Adam, who dances and plays with a toy atom — what's really amazing is how they did it.
Doctors at a hospital in Aleppo, Syria, treat a boy injured in what the government said was a chemical weapons attack on March 19. Syria's government and rebels accused each other of firing a rocket loaded with chemical agents outside of Aleppo.

Fishermen arrive on Wakatobi island in Sulawesi waters off eastern Indonesia in 2009. In the 19th century, the island's rich and unique biodiversity helped Wallace understand how species adapted to their environment — and how regions are defined by the animals that live in them.

Maleos are a prime example of an animal that has adapted to its environment, using geothermal energy to incubate their eggs rather than body heat. They dig into the earth, which is heated by hot springs, are able to sense spots that are exactly 86 to 97 degrees, and lay their eggs there.
