Instruments and Supplies RSS FeedsJanuary 2012 fourth warmest for contiguous United States, but Alaska extremely cold - During January, warmer-than-average conditions enveloped most of the contiguous United States, with widespread below-average precipitation. The overall weather pattern for the month was reflected in the lack of snow for much of the Northern Plains, Midwest, and Northeast. This scenario was in stark contrast to Alaska where several towns had their coldest January on record....Feed Source: feeds.sciencedaily.com DNA sequencing helps identify cancer cells for immune system attack - DNA sequences from tumor cells can be used to direct the immune system to attack cancer, according to scientists. The immune system relies on an intricate network of alarm bells, targets and safety brakes to determine when and what to attack. The new results suggest that scientists may now be able to combine DNA sequencing data with their knowledge of the triggers and targets that set off immune alarms to more precisely develop vaccines and other immunotherapies for cancer....
