Criminologist Believes Violent Behavior Is Biological

iStockphoto.com

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.

  • Bob Mondello's Review

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.

President Obama affirmed Tuesday that there's evidence Syrians have been attacked with chemical weapons — in particular, nerve gas.

But that's not the same as proof positive.

"We don't know how they were used, when they were used, who used them," Obama said. "We don't have a chain of custody that establishes what exactly happened."

Ask most folks who came up with the theory of evolution, and they'll tell you it was Charles Darwin.

In fact, Alfred Russel Wallace, another British naturalist, was a co-discoverer of the theory — though Darwin has gotten most of the credit. Wallace died 100 years ago this year.

Saturn Shows Off A Massive Spinning Vortex: 'The Rose'

A mammoth spinning vortex is seen on Saturn, in this "false-color" photograph released by NASA Monday. The image was captured by the Cassini spacecraft. A related image, presenting what a human eye would see, is farther down this page.

NASA is calling it "The Rose." By any other name, it's a mammoth storm on Saturn's north pole. Its eye spans an estimated 1,250 miles — 20 times the size of an average hurricane's eye on Earth. Winds in the Saturn storm's eye wall are believed to be four times as fast.

The stunning image of the spinning vortex was given "false colors" to emphasize low clouds (in red) versus high clouds (in green). NASA estimates that the clouds at the outer edge are moving at up to 330 miles per hour.

Three popular pesticides will soon be illegal in the European Union, where officials hope the change helps restore populations of honey bees, vital to crop production, to healthy levels. The new ban will be enacted in December.

"I pledge to do my utmost to ensure that our bees, which are so vital to our ecosystem and contribute over €22 billion ($28.8 billion) annually to European agriculture, are protected," said EU Health and Consumer Commissioner Tonio Borg.

Patricia East is a developmental psychologist who began her career working at an OB-GYN clinic in California. Thursday mornings at the clinic were reserved for pregnant teens, and when East arrived the waiting room would be packed with them, chair after chair of pregnant adolescents.

It was in this waiting room, East explains, that she discovered her life's work — an accidental discovery that emerged from the small talk that staff at the clinic had with their young clients as they walked them back for checkups.

Virgin Galactic's SpaceShipTwo Passes First Rocket Test

Originally published on Mon April 29, 2013 4:02 pm

Virgin Galactic's SpaceShipTwo — designed to carry paying passengers beyond Earth's atmosphere — passed a key test Monday, shooting past the speed of sound under its own rocket power.

The spacecraft developed by Sir Richard Branson's space tourism venture dropped from its mother ship over the Mojave Desert and then, for the first time, fired its engine. It hit Mach 1.2 and reached an altitude of 56,000 feet before gliding to a landing.

The Sounds of Thirsty Trees

Originally published on Sun April 28, 2013 6:38 pm

A team of physicists at Grenoble University in France discovered that trees make different sounds when they are starved for water versus when they are simply thirsty. We hear from Dr. Alexandre Ponomarenko, the lead researcher, and hear a bit of the thirsty tree sounds.
