Furthermore, the study found that children's blood levels of the long-chain Omega-3 DHA (the form found in most abundance in the brain) 'significa.. 더보기 'Terminator' Polymer 'Terminator' Polymer: Self-Healing Polymer That Spontaneously and Independently Repairs Itself Sep. 13, 2013 — Scientists report the first self-healing thermoset elastomer that requires no intervention to induce its repair. Self-healing polymers mend themselves by reforming broken cross-linking bonds. However, the cross-linking healing mechanism usually requires an external stimulus. Triggers to.. 더보기 Novel Avian Influenza A Virus Has Potential for Both Virulence and Transmissibility in Humans Novel Avian Influenza A Virus Has Potential for Both Virulence and Transmissibility in Humans Sep. 10, 2013 — A new study has found that a novel avian-origin H7N9 influenza A virus, which has recently emerged in humans, attaches moderately or abundantly to the epithelium of both the upper and lower respiratory tracts.

Research led by senior author Norman M. Weinberger, a research professor of neurobiology & beha.. 더보기 New Risk Model Sheds Light On Arsenic Risk in China's Groundwater New Risk Model Sheds Light On Arsenic Risk in China's Groundwater Aug. 22, 2013 — Arsenic-laden groundwater used for cooking and drinking could pose a risk to the health of almost 20 million people across China. This is shown by a study carried out by Eawag scientists in collaboration with Chinese colleagues and published today in Science. The estimates are based on a risk model incorporating ge.. 더보기 Wolves Howl Because They Care Wolves Howl Because They Care: Social Relationship Can Explain Variation in Vocal Production The findings shed important light on the degree to which animal vocal production can be considered as voluntary, the researchers say.
