As we continue to carry around items that insist on requiring electricity to work, portable-even wearable-energy-generating systems are looking very attractive. A group of researchers has recently looked into the use of piezoelectric materials, which generate an electric field or potential when placed under mechanical stress. By placing these materials on a rubbery or flexible surface, they created a material that can generate the highest rate of energy conversion reported for similar systems. While these are still far from the market, the metrics of the flexible piezoelectrics so far are very promising.

"A large study from Children's Hospital Boston and the Boston-based Autism Consortium finds that a genetic test that samples the entire genome, known as chromosomal microarray analysis, has about three times the detection rate for genetic changes related to autism spectrum disorders (ASDs) than standard tests. Publishing in the April issue of Pediatrics (and online March 15), the authors urge that CMA become part of the first-line genetic work-up for ASDs."

Recent formulations of sexual selection theory emphasise how mate choice can be affected by environmental factors, such as predation risk and resource quality. Women vary greatly in the extent to which they prefer male masculinity and this variation is hypothesised to reflect differences in how women resolve the trade-off between the costs (e.g., low investment) and benefits (e.g., healthy offspring) associated with choosing a masculine partner. A strong prediction of this trade-off theory is that women's masculinity preferences will be stronger in cultures where poor health is particularly harmful to survival. We investigated the relationship between women's preferences for male facial masculinity and a health index derived from World Health Organization statistics for mortality rates, life expectancies, and the impact of communicable disease. Across 30 countries, masculinity preference increased as health decreased. This relationship was independent of cross-cultural differences in wealth or women's mating strategies. These findings show non-arbitrary cross-cultural differences in facial attractiveness judgments and demonstrate the utility of trade-off theory for investigating cross-cultural variation in women's mate preferences.

Peak Oil is the point at which petroleum production reaches its greatest rate just before going into perpetual decline. In "Peak Oil and a Changing Climate," a new video series from The Nation and On The Earth productions, radio host Thom Hartmann explains that the world will reach peak oil within the next year if it hasn't already. As a nation, the United States reached peak oil in 1974, after which it became a net oil importer. Bill McKibben, Noam Chomsky, Nicole Foss, Richard Heinberg and the other scientists, researchers and writers interviewed throughout "Peak Oil and a Changing Climate" describe the diminishing returns our world can expect as it deals with the consequences of peak oil even as it continues to pretend it doesn't exist. These experts predict substantially increased transportation costs, decreased industrial production, unemployment, hunger and social chaos as the supplies of the  fuels on which we rely dwindle and eventually disappear. Chomsky urges us to anticipate the official response to peak oil based on how corporations, news organizations and other institutions have responded to global warming: obfuscation, spin and denial. James Howard Kunstler says that we cannot survive peak oil unless we "come up with a consensus about reality that is consistent with the way things really are." This documentary series hopes to help build that consensus. Click here to watch the introductory video, and check back here for new videos each Wednesday.

"We measured the direction of the body axis in 70 dogs of 37 breeds during defecation (1,893 observations) and urination (5,582 observations) over a two-year period. After complete sampling, we sorted the data according to the geomagnetic conditions prevailing during the respective sampling periods. Relative declination and intensity changes of the MF during the respective dog walks were calculated from daily magnetograms. Directional preferences of dogs under different MF conditions were analyzed and tested by means of circular statistics. Results Dogs preferred to excrete with the body being aligned along the North-south axis under calm MF conditions. This directional behavior was abolished under Unstable MF. The best predictor of the behavioral switch was the rate of change in declination, i.e., polar orientation of the MF. "
