BOSTON-- July 14, 2016-- Researchers from the Harvard Medical School - affiliated Hebrew SeniorLife Institute for Aging Research (IFAR) have found increasing evidence that delirium in older surgical patients may be associated with long-term cognitive decline. Findings from the study were published today in the July 2016 issue of Alzheimer's & Dementia: The Journal of the Alzheimer's Association.

Athens, Ga. - An international team of ecologists has identified the bat species with the greatest potential to harbor filoviruses--a family that includes Ebola virus. Writing in PLOS Neglected Tropical Diseases, they suggest that areas where many of these species overlap, notably in Southeast Asia, should be targeted for disease surveillance and virus discovery efforts.
AMHERST, Mass. - Scientists at the University of Massachusetts Amherst report in the current issue of Small that they have genetically designed a new strain of bacteria that spins out extremely thin and highly conductive wires made up of solely of non-toxic, natural amino acids.
Researchers led by microbiologist Derek Lovely say the wires, which rival the thinnest wires known to man, are produced from renewable, inexpensive feedstocks and avoid the harsh chemical processes typically used to produce nanoelectronic materials.
When adults develop blood cancer, they are frequently diagnosed with what is referred to as acute myeloid leukemia. The disease is triggered by pathological alterations of bone marrow cells, in which, in addition, an important mechanism is out of action: these cells do not die when they are damaged. Researchers from the Technical University of Munich (TUM) have now discovered a molecular signaling pathway for self-destruction that is suppressed in leukemia cells.
Scientists have discovered a new method of creating human stem cells which could solve the big problem of the large-scale production needed to fully realise the potential of these remarkable cells for understanding and treating disease.
The discovery has been made by a team of scientists at The University of Nottingham, Uppsala University and GE Healthcare in Sweden.
The best hiding place often lies behind enemy lines, as many bacteria such as the pathogens responsible for tuberculosis or typhoid have realized. They invade immune cells and can survive there, well hidden, for some time. To eliminate such invaders, the host macrophages can initiate a suicide program. Together with researchers at the Novartis Institute for Biomedical Research and ETH Zurich, the team led by Prof.
BOSTON (July 14, 2016)--Eating less may help us lead longer, healthier lives, according to the new results from a large, multicenter study, led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University. The paper, published in Aging, reveals that restricting calories by 25 percent in healthy non-obese individuals over two years, while maintaining adequate protein, vitamin, and mineral intake, can significantly lower markers of chronic inflammation without negatively affecting other parts of the immune system.
Reston, VA (July 14, 2016) - A new Harvey L. Neiman Health Policy Institute report discusses the Medicare Access and CHIP Reauthorization Act (MACRA) and its implications for radiology. The two-part series, supported by the Neiman Institute through American College of Radiology Foundation funding raised through a private practice donation, explores how radiologists may succeed in the new payment landscape.
Cancer treatment in people could be transformed thanks to a study on treating cancer in animals led by researchers from the Ontario Veterinary College (OVC) at the University of Guelph.
Their findings in mice and companion animals such as cats are already leading to clinical trials to treat people with various forms of cancer.
BOSTON - The recent emergence of bacterial infections that are resistant to many existing antibiotics is driving an urgent need for tools to quickly identify the small number of therapies that are still effective for individual patients. Currently, multi-drug resistant bacteria often must be sent to specialized laboratories for analysis, leading to several days of delay before results can guide therapy.
A team of the Lomonosov MSU researchers in collaboration with their German colleagues from the Institute of Polymer Research in Dresden (Leibniz Institute) managed to find a molecule that, to their opinion, could give the impetus to the development of organic electronics. The results of the work were published in Advanced Materials.
Why do some organisms within a single species have many offspring, while others have relatively few? A new study led by University of Minnesota researcher Emilie Snell-Rood finds that access to some nutrients may be a star player in shaping traits related to fitness such as fecundity and eye size over the long term. Given drastic increases in the availability of many nutrients due to the widespread use of fertilizers and road salts, the finding has important implications for agriculture and ecology.
WORCESTER, MA - A long non-coding RNA (lincRNA) - called lincRNA-EPS - responsible for regulating innate immunity has been identified by a team of scientists at the University of Massachusetts Medical School. Abundantly found in macrophages, lincRNA-EPS keeps the genes that trigger inflammation turned off until a pathogen is encountered. This discovery points to an unrecognized role for lincRNAs in the immune system and may lead to new insights into inflammatory diseases caused by uncontrolled immune responses such as lupus or inflammatory bowel disease.
MONTREAL, 13 July, 2016 - Scientists at the Research Institute of McGill University Health Centre (RI-MUHC) have discovered a new genetic mutation linked to osteonecrosis of the hip, specifically the femoral head - the spherical-shaped mass at the top of the femur. This breakthrough could allow doctors to identify and treat the disease before symptoms arise and potentially avoid hip replacements.
PORTLAND, Ore.- The Association for Research in Vision and Ophthalmology today published a special anniversary edition in their journal Investigative Ophthalmology & Visual Science with more than 70 articles to commemorate the 25th anniversary of the invention of Optical Coherence Tomography technology, co-invented by Oregon Health & Science University Casey Eye Institute's David Huang, M.D., Ph.D. while Huang was a Ph.D. student with James Fujimoto, Ph.D. at Massachusetts Institute of Technology.
