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 |Strategies to reduce greenhouse gases also benefit human health, according to studies published today in the medical journal The Lancet. The Lancet series highlights case studies on four climate chang...
Ecology, The Environment and Conservation |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 |The study, led by Julie Saba, MD, PhD, senior scientist and director of the Cancer Center at Children’s Hospital Oakland Research Institute (CHORI), will be featured in the December 15, 2009 issue of ...
Health and Medicine |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 |Sanderson, who published an essay with a similarly dire assertion in 2002, concludes these seven years later: “There have been landmark foreign policy acts in the past that managed to satisfy both dom...
Ecology, The Environment and Conservation |A team of scientists from Münster and the USA have now been able to show for the first time how green algae protect themselves against such damage. The journal "Nature" carries a report on t...
Life Sciences |Researchers at Huntsman Cancer Institute, in collaboration with a worldwide group of physicians and scientists, have discovered a remarkable treatment for a rare, yet debilitating, skin condition....
Health and Medicine |Two prototype devices have been developed: one for efficient disinfection of healthy skin (e.g. hands and feet) in hospitals and public spaces where bacteria can pose a lethal threat; and another to s...
Physics and Astronomy |The Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite captured a visible image of Super Typhoon Nida on November 25 at 0355 UTC (November 24 at 10:55 ...
Physics and Astronomy |In addition, the BU researchers have developed a new computational strategy to analyze this data and specifically identify key biological pathways (molecular circuits) that are active in cancer and &q...
Health and Medicine |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 |With its new Sirius Modular System for industrial controls, Siemens has succeeded not only in cutting down on the amount of wiring work but also in reducing space requirement in the control panel. At ...
Machine Engineering |"Voice disorders affect 30 percent of the general population and up to 60 percent of educators," says Plesniak. "The objective of our work is to develop a detailed understanding of the ...
Physics and Astronomy |Curiously enough, the failure arises when the insulin-producing "beta" cells, located in the pancreas, themselves fail to import insulin properly. Similar failures throughout the body, produ...
