1. "Mind-reading machine knows what the eye sees" <http://technology.newscientist.com/channel/tech/dn13415> "A device that reveals what a person sees by decoding their brain activity could soon be a reality, say researchers who have developed a more sophisticated way to extract visual stimuli from brain signals." 2. "Brain region lights up for power and profit" <http://www.newscientist.com/channel/being-human/dn13764> "When the scientists compared the two sets of brain scans, they found that the striatum showed bursts of activity as a result of both profit and praise." 3. "Are Smart People Drawn To The Arts Or Does Arts Training Make People Smarter?" <http://www.sciencedaily.com/releases/2008/03/080304150459.htm> "Participating researchers, using brain imaging studies and behavioral assessment, identified eight key points relevant to the interests of parents, students, educators, neuroscientists, and policy makers." 4. "Conquering Your Fears, One Synapse at a Time" <http://discovermagazine.com/2008/may/28-conquering-your-fears-one- synapse-at-a-time> "Every time a long-term memory or an associated emotion, like fear, is retrieved, proteins found in the synapses between neurons are degraded, allowing that memory to be updated by incoming information." 5. "Fighting the Urge to Fight the Urge" <http://www.wfs.org/Dec-janfiles/Soc_trend_MA08.htm> "Every day, we pressure ourselves to control our impulses ... Meanwhile, we can't ride the subway, turn on the TV, or open a magazine without finding an ad urging us to self-indulge. Balancing these two competing forces sometimes seems impossible. A new report from two Canadian researchers suggests why: Our capacity for self-control is far shallower than we realize." 6. "Housework helps combat anxiety and depression" <http://www.newscientist.com/channel/health/mg19826523.700> "One 20-minute session of housework or walking reduced the risk of depression by up to 20 per cent. A sporting session worked better, reducing risk by a third or more. Failing housework or sport, says Hamer, try to find something physical to do. 'Something - even for just 20 minutes a week - is better than nothing.'" 7. "The Physics of Whipped Cream" <http://science.nasa.gov/headlines/y2008/25apr_cvx2.htm> "Whipped cream performs this rapid changing act because of a phenomenon called 'shear thinning.' When part of the foam is forced to slide or 'shear' past the rest of the foam, the foam 'thins.' It becomes less like honey and more like water, allowing it to flow easily until the shearing stops." 8. "Is It Wednesday? Better Bring an Umbrella." <http://discovermagazine.com/2008/may/30-wednesday-better-bring-an- umbrella> "This is due to microscopic particles of soot and other pollutants that heighten rainfall, Rosenfeld concludes. Particulate emissions peak in the middle of the workweek because that is when there is more traffic and higher demand for electric power, according to the Environmental Protection Agency (EPA)."
