In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery, described in the Feb. 3 issue of Science Express, can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams.

Children who grow up in poverty have health problems as adults. But a new study finds that poor adolescents who live in communities with more social cohesiveness and control get some measure of protection; they’re less likely to smoke and be obese as adolescents. (more…)
The Youtube page sasy, it was on 28th January. The horrific incident took place in Alexandria, Egypt.
GAINESVILLE, Fla. — Twenty years after biologists attempted to determine the ecological damages to marine life from the Exxon Valdez oil spill, scientists dealing with the BP disaster find themselves with the same problem: the lack of critical data to determine the ecological consequences of human-induced environmental disasters, a University of Florida researcher said.

They were called the Eighth Wonder of the World. Until the late 19th century, New Zealand’s Pink and White Terraces along Lake Rotomahana on the North Island, attracted tourists from around the world, interested in seeing the beautiful natural formations created by a large geothermal system. But the eruption of Mt. Tarawera on June 10, 1886, buried the terraces in sediment and caused the lake basin to enlarge, engulfing the land where the terraces stood. For more than a century, people have speculated whether any part of the Pink and White Terraces survived the eruption. (more…)
ANN ARBOR, Mich.— DNA, that marvelous, twisty molecule of life, has an alter ego, research at the University of Michigan and the University of California, Irvine reveals. (more…)
WASHINGTON — Five days before intense monsoonal deluges unleashed vast floods across Pakistan last July, computer models at a European weather-forecasting center were giving clear indications that the downpours were imminent. Now, a new scientific study that retrospectively examines the raw data from these computer models, has confirmed that, if the information had been processed, forecasters could have predicted extremely accurate rainfall totals 8-10 days beforehand.

Disasters — both natural and manmade — can strike anywhere and they often hit without warning, so they can be difficult to prepare for. But what happens afterward? How do people cope following disasters? In a new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, George Bonanno, Chris R. Brewin, Krzysztof Kaniasty, and Annette M. La Greca review the psychological effects of disasters and why some individuals have a harder time recovering than do others.
Individuals exposed to disaster may experience a number of psychological problems including PTSD, grief, anxiety, and increased substance abuse, but the evidence shows that less than 30% of adults experience severe, lasting levels of these problems. The majority of people exposed to a disaster experience passing distress but return to psychological health. In other words, people tend to be psychologically resilient. (more…)
