POPSQuarter Of All Teens Plan To Buy An iPhone There are lots of teens who hold down part time jobs, and they don't have to deal with the same sort of economic woes as their parents. So the kid market may provide Apple with a little bit of recession-proofing.

POPSEvolution stops here ? This is an interesting read, yet biological evolution is only part of the story of human evolution, perhaps a tiny part at that. Moreover, biodiversity in human populations have new sources that are not considered in this article. Many genomes that would have been selected out of the gene pool in older days are now propagated. Made a clip about that a while ago.

POPS'Old-boy's club holding back innovation We all now have access to a vast amount of research and data on the net. a Few people would have absolutely no hope, but the networks being created on the web, are places where anyone can comment, or include findings, so the pieces can start coming together more quickly. It isn't what we know that is important. it's what we do with the knowledge

POPS Brain's Hub of Fear Found The results of the study, funded by the National Institutes of Health, the National Science Foundation, Burroughs Wellcome Fund, the Center for Behavioral Neuroscience and the Yerkes Center, are detailed in the October issue of the journal Nature Neuroscience. The genetically engineered virus was injected into the amygdala of the mice by Emory graduate student Kimberly Maguschak. The amygdala is a part of the brain thought to be important for forming memories of emotionally charged events. "We found that after beta-catenin is taken out, the mice can still learn to fear the shocks," Maguschak said. "But two days later, their fear doesn't seem to be retained because they spend half as much time freezing in response to the tone." So it appears that beta-catenin is turned on in the amygdala to help in signaling during the learning process, Maguschak said.

POPSPersistince affects student performance This fascinating Scientific American article makes the case that an attitude of persistence and hard work leads to greater learning and achievement. What it doesn't mention (but is also true) is that persistence actually impacts intelligence - gene expression is affected by stimulation and persistence.

POPSThe Startle Reflex: Key to Your Politics "Researchers shied away from using labels such as conservative and liberal in their study, but they concede that volunteers who registered a heightened sense of threat also tended to subscribe to conservative attitudes. "It's not that conservatives are 'fraidy-cats," says Kevin Smith, a political science professor at the University of Nebraska–Lincoln and one of the study's co-authors. "It's that people who support socially protective policies — which, yes, can be interpreted as people taking a conservative position on those policies — are more sensitive to environmental threat."

POPSUsing AI to find biomarkers of calorie restriction Novel artificial intelligence methodologies were applied to analyze gene expression microarray data gathered from mice under a calorie restriction (CR) regimen. The data were gathered from three previously published mouse studies; these datasets were merged together into a single composite dataset for the purpose of conducting a broader-based analysis. The result was a list of genes that are important for the impact of CR on lifespan, not necessarily in terms of their individual actions but in terms of their interactions with other genes. Furthermore, a map of gene interrelationships was provided, suggesting which intergene interactions are most important for the effect of CR on life extension.

POPSPrickly Blonde Normal-colour hedgehogs produce blondes only if both parents carry the blonde gene. As inbreeding occurred within the captive population, the rare gene was passed on. “The two types interbreed but have differing characteristics. The brown ones tend to be more tenacious and aggressive, while blondes are more placid and amenable to handling.“ said Alderney Resident and Hedgehog carer Barbara Head.
