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 |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 |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 |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 |These CO2 emissions increased at a rate of 3.4% per year from 2000 to 2008, in contrast to 1% each year in the previous decade, scientists from the Global Carbon Project report in the current issue of...
Earth Sciences |Robert Whittlesey and John Dabiri of the California Institute of Technology have developed a potentially more efficient wind farm design that maximizes the efficiency of land usage. They based their a...
Physics and Astronomy |The researchers will present their work next week at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics will take place from November 22-24 at the Minneap...
Medical Engineering |Economically viable production of a perennial grass monoculture from which substantial quantities of biomass are removed annually is expected to require nitrogen fertilizer.An agronomist at Ok...
Agricultural and Forestry Science |One of the main challenges of computed tomography (CT) is to provide excellent image quality while exposing patients to the lowest possible dose of radiation. Reductions in dose application typically ...
Medical Engineering |Human as well as most living organisms on earth possess circadian a (24-hour) life rhythm. This rhythm is generated from an internal clock that is located in the brain and regulates many bodily functi...
Life Sciences |Mention of arsenic poisoning usually brings to mind underhanded murder. However, the danger of arsenic poisoning from contaminated drinking water is far greater. Low concentrations of arsenic are foun...
Life Sciences |The appropriate scanner can read and process the data contained in the label. »Smart labels« can be affixed to goods under production conditions of up to 100 degrees Celsius. But at higher temperature...
Information Technology |Reporting in Oncogene, a publication of Nature Publishing Group, the research teams of Anthony Atala, M.D., director of the Wake Forest Institute for Regenerative Medicine, and Markus Hengstschläger, ...
