“Then, all of the sudden, one goes off and, poof, they all do,” said Ms. Hickerson of Flower Garden Banks. “They all release at the same time.”“It’s like a wave at a stadium,” she added. “You see it start at one side and go across. It’s amazing. You can’t make this stuff up.”In nighttime dives of recent years, videographers, including Ms. Hickerson, have taken lights and cameras beneath the waves to document the natural wonder, at times zooming in so close that viewers can see the swelling and ..>> view originalAttract bees, butterflies to pollinate your garden

Chameleons have powerful, speedy tongues. If one of these colorful lizards decides it wants a snack, the unsuspecting prey is in the animal's mouth within seconds. The chameleon simply fires its long, elastic tongue out of its mouth at high speed and whips it back just as fast, with the cricket or other tasty morsel stuck to the tip of the long muscle.But how is it that the chameleon's snack stays attached to its tongue through this whiplash-inducing ride?Biologists have suggested several hypot..>> view originalChina builds world's fastest supercomputer without US chips
China on Monday revealed its latest supercomputer, a monolithic system with 10.65 million compute cores built entirely with Chinese microprocessors. This follows a U.S. government decision last year to deny China access to Intel's fastest microprocessors. There is no U.S.-made system that comes close to the performance of China's new system, the Sunway TaihuLight. Its theoretical peak performance is 124.5 petaflops, according to the latest biannual release today of the world's Top500 supe..>> view originalNASA Electric Research Plane Gets X Number, New Name
With 14 electric motors turning propellers and all of them integrated into a uniquely-designed wing, NASA will test new propulsion technology using an experimental airplane now designated the X-57 and nicknamed "Maxwell." NASA Administrator Charles Bolden highlighted the agency's first X-plane designation in a decade during his keynote speech Friday in Washington at the American Institute of Aeronautics and Astronautics (AIAA) annual Aviation and Aeronautics Forum and Exposition, commonl..>> view originalRare Summer Solstice Full Moon, 1st Since 1948, Rises Tonight: Watch It Live

Two black holes collided in space, 1.4 billion light years from Earth. The ripples in space-time created by this collision were detected by the Laser Interferometer Gravitational Wave Observatory (LIGO). Credit: LIGO There was big news in astrophysics this week: An experiment detected ripples in space-time, known as gravitational waves, created by two black holes colliding in space 1.4 billion light-years from Earth. That certainly sounds … complicated. But what's the big deal, exac..>> view original'Amazing': Scientists crack mystery of Venus's vanished water
(Krystofer Kim/NASA Goddard Conceptual Image Lab) By human standards, a descent onto Venus mirrors a fall through different circles of hell. As visitors approach, they would first pass through a thick haze of sulfuric acid. Further below are heavy metal snows that drift over Venusian mountain peaks. Finally, upon touching down, the average surface temperatures — ranging from 800 to 900 degrees Fahrenheit — would bake explorers like a Neapolitan pizza. Even the gas molecules from the visito..>> view originalRare Newborn Planet May Be the Youngest Ever Detected
A distant, Neptune-size planet 500 light-years from Earth appears to be the youngest fully formed exoplanet ever found crossing its star, raising questions about how it formed so close, so quickly. Researchers first found the planet, which whisks around its star every five days, using the Kepler space telescope currently orbiting Earth. Its star is only 5 million to 10 million years old, suggesting that the planet is a similar age — incredibly young, on a cosmic scale. Researchers said..>> view originalDell Launches New High Performance Computing Systems and Unveils New Innovations to Bring Supercomputing ...
