Rising dust storms a health problem, even continents away; infant mortality worst in drylands: Report
Growing desertification worldwide threatens to swell by millions the number of poor forced to seek new homes and livelihoods. And a rising number of large, intense dust storms plaguing many areas menace the health of people even continents away, international experts warn in a new report.
Thick storms rising out of the Gobi Desert affect much of China, Korea and Japan and even reduce air quality over North America, according to Ecosystems and Human Well-Being: Desertification Synthesis. The report is based on information generated for the Millennium Ecosystem Assessment (MA), a $22 million, four-year global study by 1,300 experts from 95 countries. "An increase in desertification-related dust storms is widely considered to be a cause of ill-health (fever, coughing, sore eyes) during the dry season," says the report. "Dust emanating from (the Gobi desert) and the Sahara has also been implicated in respiratory problems as far away as North America and has affected coral reefs in the Caribbean."

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
