A new video reveals just how close NASA came last year to losing its $500 million Fermi Gamma-ray Space Telescope in a narrowly averted collision with a defunct, Cold War-era Soviet spy satellite.
On March 29, 2012, Julie McEnery, the project scientist for Fermi, received an automatically generated email warning that the two satellites were due in just a few days to pass within 700 feet of one another as their respective orbits crossed.
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.
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.
A huge storm is seen on Saturn's north pole, in this color image from NASA's Cassini spacecraft. NASA used red, green and blue spectral filters "to create this natural-color view, which is what the human eye would see if we were there at Saturn."

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 — 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.
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.
