Laser device may end pin pricks, improve quality of life for diabetics
(Princeton University, Engineering School) Princeton University researchers have developed a way to use a laser to measure people's blood sugar, and, with more work to shrink the laser system to a portable size, the technique could allow diabetics to check their condition without pricking themselves to draw blood.

BIDMC researchers named among 'the most influential scientific minds'
(Beth Israel Deaconess Medical Center) Nine researchers from Beth Israel Deaconess Medical Center have been included in 'The World's Most Influential Scientific Minds 2014,' for their highly cited publications.

Grants will fund landmark aging research at Waterloo
(University of Waterloo) A landmark study aimed at improving the food intake, health and quality of life of older adults in long-term care homes is among three projects at the University of Waterloo receiving close to $1.5 million in grants from the Canadian Institutes of Health Research.

Water window imaging opportunity
(Springer) Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometer range, which are not absorbed by the water in biological tissues. A new theoretical study identifies the physical mechanism needed to efficiently generate harmonic radiations at high laser intensities that occur beyond the saturation threshold of atoms and molecules. These findings, aimed at improving conventional methods of coherent radiation production to reach the water window, were published in EPJ D.

Arctic sea ice influenced force of the Gulf Stream
(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) The force of the Gulf Stream was significantly influenced by the sea ice situation in the Fram Strait in the past 30,000 years. On the basis of biomarkers in deposits on the seafloor, geologists from the Alfred Wegener Institute managed for the first time to reconstruct when and how the marine region between Greenland and Svalbard was covered with ice in the past and in what way the Gulf Stream reacted when the sea ice cover suddenly broke up.

800 meters beneath Antarctic ice sheet, subglacial lake holds viable microbial ecosystems
(Louisiana State University) According to LSU's Brent Christner, the paper's lead author and a researcher with the NSF-funded Whillans Ice Stream Subglacial Access Research Drilling, or WISSARD, project, 'hidden beneath a half-mile of ice in Antarctica is an unexplored part of our biosphere. WISSARD has provided a glimpse of the nature of microbial life that may lurk under more than five million square miles of ice sheet.'

Conclusive evidence on role of circulating mesenchymal stem cells in organ injury
(Mary Ann Liebert, Inc./Genetic Engineering News) Mesenchymal stem cells are present in virtually every type of human tissue and may help in organ regeneration after injury. But the theory that MSCs are released from the bone marrow into the blood stream following organ damage, and migrate to the site of injury, has long been debated.

Research offers insight into cellular biology of colorectal cancer
(University of Kansas) Kristi Neufeld has spent the better part of her career trying to understand the various activities of APC, a protein whose functional loss is thought to initiate roughly 80 percent of all colon polyps.

American Society of Human Genetics 2014 Annual Meeting
(American Society of Human Genetics) The American Society of Human Genetics 2014 Annual Meeting will include invited and platform (oral) sessions and other presentations of the latest research in human genetics. Advance press registration is now available.

Amplitude of sensory nerve action potential in early stage diabetic peripheral neuropathy
(Neural Regeneration Research) Early diagnosis of diabetic peripheral neuropathy is important for the successful treatment of diabetes mellitus.
