By tuning lighting devices to work more efficiently with the human brain the researchers believe billions of dollars in energy costs could be saved. The research was conducted by Stephen Macknik, PhD, of Barrow’s Laboratory … more… Optogenetics illuminates pathways of motivation and depression through brain November 20, 2012   Effects of  stimulating the medial prefrontal cortex (mPFC) (a) Optogenetic inhibition of nerve axons in the dorsal raphe nucleus (DRN), implicated in major depressive disorder (b) Fluorescence in the DRN detects effects. (Credit: Melissa R. Warden et al./Nature) Karl Deisseroth, MD, PhD, a professor of bioengineering and of psychiatry and behavioral sciences at Stanford University, and postdoctoral scholar Melissa Warden, PhD, … more… Breakthrough nanoparticle halts multiple sclerosis, diabetes, allergies November 20, 2012   Northwestern Medicine researchers have developed a biodegradable nanoparticle  that stealthily delivers an antigen that tricks the immune system into stopping its attack on myelin and haltd a model of relapsing remitting multiple sclerosis (MS) in mice, according to new research. The nanoparticles can also be applied to other immune-mediated diseases, including Type 1 diabetes, food allergies, and asthma. … more… How to create an animated character from your facial expressions in real time November 20, 2012   Faceshift, announced Monday, is software that uses Kinect and similar cameras to read your face and create a moving avatar from it. It could enhance the future of video games and make video chats more fun, says Thibaut Weise, founder of Faceshift, a spinoff of EPFL’s Computer Graphics and Geometry Laboratory. The software needs only ten minutes to recognize your face as … more… A warning system for the planet November 20, 2012   There is no centralized system to monitor and report changes in the Earth’s life-support systems. So scientists in 77 nations have established the Group on Earth Observations (GEO) and the Group on Earth Observation Biodiversity Observation Network (GEO BON), which integrates existing data streams into one platform to provide a  global warning system for Earth’s biological and social … more… New books The Last Pictures author Trevor Paglen   Human civilizations’ longest lasting artifacts are not the great Pyramids of Giza, nor the cave paintings at Lascaux, but the communications satellites that circle our planet. In a stationary orbit above the equator, the satellites that broadcast our TV signals, route our phone calls, and process our credit card transactions experience no atmospheric drag.
