The peaks and valleys of silicon Posted: 26 Jun 2015 10:06 AM PDT Scientists have created a new method for generating a 2D semiconducting material that could one day replace silicon in electronics. The demand for a silicon material aided the discovery of graphene, a single layer of graphite -- which won the Nobel Prize in Physics in 2010. Since this time, scientists and engineers have developed many two-dimensional (2D) material innovations -- layered materials with the thickness of only one atom or a few atoms. One such layered 2D material is black arsenic phosphorus.

Scientists identify 'decoy' molecule that may sharply reduce risk of flu death Posted: 26 Jun 2015 10:06 AM PDT The flu virus can be lethal. But what is often just as dangerous is the body's own reaction to the invader. The immune counterattack can end up harming the body's own tissues, causing deadly damage. Now, a researcher has, for the first time, uncovered new details about how this response plays out. And he has identified a 'decoy' molecule that can rein in this runaway inflammatory response.

Having a stroke? Where you are makes a huge difference in your treatment Posted: 26 Jun 2015 09:57 AM PDT It looks like a crazy quilt spread over the continent. But a new map of emergency stroke care in America shows just how much of a patchwork system we still have for delivering the most effective stroke treatment. And thousands of people a year may end up unnecessarily disabled as a result.

Light fixture kills bacteria safely, continuously Posted: 26 Jun 2015 07:56 AM PDT A new light fixture uses Continuous Environmental Disinfection technology to continuously kill harmful bacteria linked to hospital acquired infections (HAIs). The technology behind the Indigo-Clean™ inactivates a wide range of micro-organisms that are known causes of HAIs, including MRSA (Methicillin-resistant Staphylococcus aureus), C.difficile and VRE (Vancomycin-resistant Enterococcus).

Analysis shows increased carbon intensity from Canadian oil sands Posted: 26 Jun 2015 07:51 AM PDT Gasoline and diesel refined from Canadian oil sands has a higher carbon impact than fuels derived from conventional domestic crude sources, a new study concludes.
