Mammals have evolved a complex system for controlling bone remodelling. Babies require calcium for healthy bones and they obtain it from their mother's milk. Nursing mothers release calcium from ...
Life Sciences |During the late Pleistocene, 40,000 to 10,000 years ago, North America lost over 50 percent of its large mammal species. These species include mammoths, mastodons, giant ground sloths, among many othe...
Earth Sciences |Their experiments in mice revealed that the daily waxing and waning of thousands of genes in the liver—the body’s metabolic clearinghouse—is mostly controlled by food intake and not by the body’s circ...
Life Sciences |The same type of large industrial sized X-ray scanners that NASA uses to detect flaws in the space shuttle’s behemoth solid fuel rockets is now allowing scientists to peek inside the giant head of a w...
Life Sciences |The purpose of this study published in the December 2009 issue of Experimental Biology and Medicine was to identify chromosomal regions containing genes that affect the variation in the plasma levels ...
Health and Medicine |The research, federally funded by the National Science Foundation, appears in the Nov. 20 edition of the journal Science. "We're learning the rules about how these lithographic parti...
Life Sciences |Researchers at the Stanford University School of Medicine have identified a set of molecular brakes that stabilize the developing brain's circuitry. Moreover, experimentally removing those brakes...
Life Sciences |Because most forested areas are in mountainous regions, 40% of U.S. forests are in landslide hazard areas. Thus, the interaction between soil development and mass wasting is critical to understanding ...
Agricultural and Forestry Science |Capitalizing on their previous work to decode the genome of the poplar tree, the research team examined how poplar trees use their 45,000 genes to respond to drought. Campbell and PhD student ...
Agricultural and Forestry Science |Universitat Autònoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brain...
Health and Medicine |Promising results have led to the design of a clinical trial that will soon be under way to test a compound -- called PU-H71 -- in human patients. This compound is in a new class of drugs, called heat...
Life Sciences |Now, researchers at the University of Michigan, along with colleagues in Belgium, have discovered a new antioxidant system that protects single cysteines. The research appears in the Nov. 20 issue of ...
Life Sciences |Researchers at the University of Illinois have developed a technique for fabricating three-dimensional, single-crystalline silicon structures from thin films by coupling photolithography and a self-fo...
Physics and Astronomy |A commonly inherited gene deletion can increase the likelihood of immune complications following bone marrow transplantation, an international team of researchers reports in the November 22 advance on...
Life Sciences |The discovery paves the way for an entirely new way to approach the hydrogen-storage problem. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen (H2) ...
