Heart of space weather observed in action

Posted: 15 Jul 2013 01:49 PM PDT

Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions and releasing a jolt of magnetic energy. This process lies at the heart of giant explosions on the sun, such as solar flares and coronal mass ejections, which can fling radiation and particles across the solar system.

Computer as smart as a 4-year-old? Researchers IQ test new artificial intelligence system

Posted: 15 Jul 2013 12:10 PM PDT

Artificial and natural knowledge researchers IQ-tested one of the best available artificial intelligence systems and learned that it's about as smart as the average 4-year-old.

Hubble finds new Neptune moon: Smallest known moon in the Neptunian system

Posted: 15 Jul 2013 10:20 AM PDT

NASA's Hubble Space Telescope has discovered a new moon orbiting the distant blue-green planet Neptune, the 14th known to be circling the giant planet.

Share robotic frogs help turn a boring mating call into a serenade

Posted: 15 Jul 2013 08:48 AM PDT

With the help of a robotic frog, biologists have discovered that two wrong mating calls can make a right for female tĂșngara frogs. The "rather bizarre" result may provide insight into how complex traits evolve by hooking together much simpler traits.

Solving DNA puzzles is overwhelming computer systems, researchers warn

Scientists in the fast-growing field of computational genomics are getting lots of data but lack the computer power needed to analyze it quickly.

New form of carbon: Grossly warped 'nanographene'

Posted: 15 Jul 2013 07:56 AM PDT

By introducing multiple odd-membered ring defects into a graphene lattice, researchers have experimentally demonstrated that the electronic properties of graphene can be modified in a predictable manner through precisely controlled chemical synthesis.

Biochemists uphold law of physics

Posted: 15 Jul 2013 06:12 AM PDT

Experiments by biochemists show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein molecules -- specifically, a protein that unwinds DNA.

Smallest puzzle in the world

Posted: 15 Jul 2013 04:03 AM PDT

Researchers have created three puzzle pieces of less than 1 mm in size each that may be put together to make what is likely the smallest puzzle in the world. For production, researchers used a new process to manufacture microstructured casting molds. Inexpensive series production is combined with highest precision on the microscale to produce such things as components for watches, engines, or medical products. Now, large series of smallest parts can be injection-molded with the highest accuracy. 

Taking the 'random' out of a random laser

Posted: 15 Jul 2013 04:02 AM PDT

Random Lasers are tiny structures emitting light irregularly into different directions. Scientists have now shown that these exotic light sources can be accurately controlled.

The universe or the brain: Where does math originate?

Posted: 15 Jul 2013 04:01 AM PDT

Four scientists debate whether math is an inherent part of the universe, or merely how our brains cope with - and explain - our environment.
