With a moment of silence, prayers and anti-nuclear rallies, Japan marked on Sunday one year since an earthquake and tsunami killed thousands and set off a radiation crisis that shattered public trust in atomic power and the nation's leaders.
Hot towers, or towering thunderclouds that give off an excessive amount of latent heat, usually indicate a tropical cyclone will strengthen in six hours, and NASA's TRMM satellite saw some of them as it passed by Tropical Storm Koji.
A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere no larger than a city. In October 2010, a neutron star near the center of our galaxy erupted with hundreds of X-ray bursts that were powered by ...
If you've been thinking our world is more green than frozen these days, you're right. A recent study has found that spring is indeed arriving earlier - and autumn later - in the suburbs of Baltimore and Washington, D.C. The reason? The urban landscape traps heat in the summer and holds it throughout...
ICAP at Columbia University's Mailman School of Public Health is part of a network of research organizations that jointly released results, finding that HIV infection rates of black women living in certain parts of the U.S. are higher than previously estimated for black adolescent and women living i...
An international team of physicists has determined a key parameter, which governs how neutrinos behave. This discovery measures a critical linchpin in the study of the tiny particles and in advancing the understanding of how these building blocks of all things, from galaxies to tea cups, came to be.
A group of plant scientists is warning federal regulators that action is needed to mitigate a growing problem with biotech corn that is losing its resistance to plant-damaging pests.
hanks to the presence of a natural "zoom lens" in space, University of Chicago scientists working with NASA's Hubble Space Telescope have obtained a uniquely close-up look at the brightest gravitationally magnified galaxy yet discovered. The imagery offers a visually striking example of gravitati...
The detailed feather pattern and color of Microraptor--a pigeon-sized, four-winged dinosaur that lived about 120 million years ago--had a glossy iridescent sheen. Its tail was narrow and adorned with a pair of streamer feathers, suggesting the importance of display in the early evolution of feath...
On the one-year anniversary of the devastating Japanese tsunami, engineers from the USC Viterbi School of Engineering Tsunami Research Center are working with the State of California to better understand the damaging currents caused by tsunamis.
"The summit included leading scientists and researchers across all of the broad disciplines related to osteoarthritis, ranging from very basic cell and molecular biology, to biomechanics, to epidemiology and clinical trials," said Steven Goldring, M.D., chief scientific officer at Hospital for Speci...
Desert ants have adapted to a life in a barren environment which only provides very few landmarks for orientation. Apart from visual cues and odors the ants use the polarized sunlight as a compass and count their steps in order to return safely to their home after searching for food. In experiments ...
