 |  Stanford researchers hear the sound of quantum drums
Forty years ago, mathematician Mark Kac asked the theoretical question, "Can one hear the shape of a drum?"
http://hypography.com/gallery/files/2/5/2/6/1151490coverF_thumb.jpgIf drums of different shapes always produce their own unique sound spectrum, then it should be possible to...  |

| | Avian origins: new analysis confirms ancient beginnings
Did modern birds originate around the time of the dinosaurs' demise, or have they been around far longer?
The question is at the center of a sometimes contentious "rocks versus clocks" debate between paleontologists, whose estimates are based on the fossil record, and scientists who... |

| | Racing Ahead at the Speed of Light
Imagine trying to catch up to something moving close to the speed of light - the fastest anything can move - and sending ahead information in time to make mid-path flight corrections. Impossible? Not quite. Physicists at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator at... |

| | Helium-8 study gives insight into nuclear theory, neutron stars
The most neutron-rich matter that can be made on Earth—the nucleus of the helium-8 atom—has been created, trapped and characterized by researchers at the U.S. Department of Energy's Argonne National Laboratory. This new measurement gives rise to several significant consequences in nuclear... |

Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara. About half of these bubbles dissolve into the ocean, but the fate of this dissolved methane remains uncertain. Researchers at the University of California, Santa... |

Weddell seals, animals that dive and hunt under the Antarctic sea ice, can hold their breath for as long as 90 minutes and remain active and mentally alert the whole time. The seals aren't fazed at all by low levels of oxygen that would cause humans to black out. What's their secret? ... |
