More detailed analysis of how cells react to stress

( University of Zurich) Stress in the body's cells is both the cause and consequence of inflammatory diseases or cancer. The cells react to stress to protect themselves. Researchers at the University of Zurich have now developed a new technique that allows studying a fundamental response to stress in much more detail than previously possible: the ADP-ribosylation of chromatin. In the long term, this method could help finding ways of blocking disease-causing processes.

New algorithm improves speed and accuracy of pedestrian detection

( University of California - San Diego) Electrical engineers at the University of California, San Diego have developed a pedestrian detection system that performs in near real-time (two-four frames per second) and with higher accuracy (close to half the error) compared to existing systems. The technology, which incorporates deep learning models, could be used in 'smart' vehicles, robotics and image and video search systems.

IU's Katy Börner, Noretta Koertge and Jessica Gall Myrick to present at AAAS 2016

( Indiana University) Faculty experts from Indiana University will join thousands of scientists converging on Washington, DC, from Feb. 11 to 15 at the 2016 Annual Meeting of the American Association for the Advancement of Science.

Early human ancestor didn't have the jaws of a nutcracker, study finds

( Washington University in St. Louis) Research published in 2012 garnered international attention by suggesting that a possible early human ancestor had lived on a diverse woodland diet including hard foods mixed in with tree bark, fruit, leaves and other plant products. But new research by an international team of researchers now shows that Australopithecus sediba didn't have the jaw and tooth structure necessary to exist on a steady diet of hard foods.

Study compares effectiveness of phone-based and web-based smoking cessation programs in four states

( Wiley) A new analysis indicates that states' Web-based and phone-based tobacco cessation programs can help people quit smoking, but certain personal characteristics may lead individuals to prefer one type of program over the other.

Muscles on-a-chip provide insight into cardiac stem cell therapies

( Rockefeller University Press) Stem cell-derived heart muscle cells may fail to effectively replace damaged cardiac tissue because they don't contract strongly enough, according to a study in The Journal of Cell Biology. The study, 'Coupling Primary and Stem Cell-Derived Cardiomyocytes in an In Vitro Model of Cardiac Cell Therapy,' by Yvonne Aratyn-Schaus and Francesco Pasqualini and colleagues, may help explain why stem cell-based therapies have so far shown limited benefits for heart attack patients in clinical trials.

Wirelessly supplying power to brain

( Toyohashi University of Technology) The researchers at Toyohashi University of Technology have developed a technique to implement silicon large-scale integration chips in a very thin film of thickness 10 μm. This fabrication method has the potential to realize a low-invasive flexible device for monitoring brain activity. This study will contribute to the development of brain-machine interface systems.

Cambridge researcher develops smartphone app to map Swiss-German dialects

( University of Cambridge) Researchers from the Universities of Cambridge, Zurich and Bern have taken advantage of 'crowdsourcing' to gather new information on the spread of dialects in German-speaking Switzerland, which has been recently published as a paper in PLOS One.

Multinational companies perform majority of US business R&D

( National Science Foundation) Multinational companies perform the majority of all research and development (R&D) done by companies located in the Unites States, according to a new report from the National Center for Science and Engineering Statistics.

Online shopping might not be as green as we thought

( University of Delaware) A study by researchers in the Delaware Center for Transportation provides insight into the impacts of home shopping on vehicle operations and greenhouse gas emissions.
