International studies describe current state of the Arctic coasts The coastline in Arctic regions reacts to climate change with increased erosion and retreats by half a meter per year on average. This means substantial changes for Arctic ecosystems near the coast and the population living there. A consortium of more than thirty scientists from ten countries, including researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association and from the...

The American Geophysical Union has selected a research paper detailing observations of Mercury's magnetosphere during the probe's third flyby as a "Research Highlight" in today's issue of Eos, the AGU's weekly online and print newspaper. "Observations of Kelvin-Helmholtz waves along the dusk-side boundary of Mercury's magnetosphere during MESSENGER's third flyby," by Scott Boardsen and coauthors, originally published in Geophysical Research Letters, is available online at...

The long-term effects of pesticides on living organisms in rivers and on water quality can now be assessed more easily. Researchers from the Helmholtz Centre for Environmental Research (UFZ) have developed a tool that can estimate the harmful effect of pesticides, such as those flushed into rivers and streams from agricultural land, within minutes. "It used to be very difficult to detect which chronic effects occur," explains Dr Matthias Liess, head of the UFZ's System Ecotoxicology...

The reintroduction of the Large Blue butterfly to Britain offers lessons in helping plants and animals threatened by climate change, scientists said. The Large Blue, whose scientific name is Maculinea arion, was successfully reintroduced 25 years ago after becoming extinct in 1979, scientists at the Helmholtz Center for Environmental Research said in a release Friday. Large Blues imported from Sweden were aided by the creation of small heat-shielded habitats, which could give today's...

University of Illinois scientists say they have created the first acoustic superlens, an innovation that could impact several technologies. The researchers, led by Professor Nicholas Fang, said their achievement could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and underwater stealth technology. The scientists said they successfully focused ultrasound waves through a flat metamaterial lens onto a spot about...

In the study, the Icelandic company Decode Genetics together with Helmholtz Zentrum Mnchen and a number of other international research institutes performed a genome-wide association scan of more than 50,000 test persons. The researchers found several sequence variants associated with asthma."Two of the detected sequence variants are of significance for a biochemical pathway in the interleukin-1 cluster," explained Dr. Matthias Wjst, who was one of the initiators of the study at the Institute...

The international GIANT (Genetic Investigation of Anthropometric Parameters) consortium works on the discovery of obesity genes. So far, the scientists have analyzed two million DNA variations in 15 genome-wide association studies with a total of more than 32,000 participants. The hereby identified candidate genes were validated in 14 further studies including 59,000 participants. In addition to the FTO and MC4R genes already known, it was now possible for six more obesity genes to be...
