Is the universe a hologram? Apr 27th 2015, 14:16 The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange curved spaces. New results suggest that the holographic principle also holds in flat spaces. Our own universe could in fact be two dimensional and only appear three dimensional -- just like a hologram.

Mathematics reveals how fluid flow affects bacteria Apr 28th 2015, 14:59 Researchers have used mathematical equations to shed new light on how flowing fluid hinders the movement of bacteria in their search for food. Patient portals could widen health disparities Apr 28th 2015, 13:19 Online patient portals are increasingly important for doctor-patient communication and access to health care information. But patient portals could widen the gap in health disparities. Patients with low health literacy, less education and who are African American were much less likely to use these portals compared with white patients and those who were more health literate. These people lose the opportunity to easily engage their doctor about health concerns or medications, quickly refill prescriptions and get lab results, authors of a new report say.

The findings shed light on genetic interactions that underlie human diseases, the investigators say. Text messaging reduces pain medicine requirements during surgery Apr 27th 2015, 15:26 Patients who text messaged a stranger just before minor surgeries required less supplemental pain relief than patients receiving standard therapy or distraction techniques, according to a study. While both texting conditions reduced the need for pain management better than standard surgery, only texting a stranger reduced it beyond the distraction method of playing a mobile phone game, investigators say. Computer cooling system could save U. S. $6. 3 billion in electricity a year Apr 27th 2015, 14:13 A patented passive cooling system for computer processors could save U.S. consumers more than 6.3 billion dollars per year in energy costs. How hospitals can improve outcomes of weekend surgeries Apr 26th 2015, 01:56 Studies have shown that patients who undergo surgeries on weekends tend to experience longer hospital stays and higher mortality rates and readmissions. For the first time, a new study has identified five resources that can help hospitals overcome this 'weekend effect': increased nurse-to-bed ratio; full adoption of electronic medical records; inpatient physical rehabilitation; a home-health program; and a pain management program. Scientists develop first liquid nanolaser Apr 25th 2015, 01:31 Scientists have developed the first liquid nanoscale laser. And it's tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a 'lab on a chip' for medical diagnostics. In addition to changing color in real time, the liquid nanolaser has additional advantages: it is simple to make, inexpensive to produce and operates at room temperature.
