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 |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 |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, ...
Life Sciences |Experiments show that infected red blood cells are stiffer and stickier than normal ones -- in the later stages of the disease, up to 10 times stiffer. They also tend to adhere to the endothelial cell...
Physics and Astronomy |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 |Scientists have known that the mutated form of the human gene – one of three consistently associated with schizophrenia – mildly disrupts the transmission of chemical signals between nerve cells in th...
Life Sciences |The researchers sought to discover the cognitive processes underlying searching. They examined the search habits of 72 participants while conducting a total of 426 searching tasks. They found that sea...
Information Technology |The technology, based on one or more unique physical attributes of individual tags rather than information stored on them, will prevent the production of counterfeit tags and thus greatly enhance both...
Information Technology |How does a social situation actually function when the lives of both the players and others are under threat? Many of us remember April 24, 1975, when six members of the Red Army Fraction occupied and...
Social Sciences |Prions are causing fatal and infectious diseases of the nervous system, such as the mad cow disease (BSE), scrapie in sheep or Creutzfeldt-Jakob disease in humans. Scientists of Helmholtz Zentrum Münc...
Life Sciences |This exceptionally detailed edge-on view of NGC 4710 taken by the Advanced Camera for Surveys (ACS) aboard Hubble reveals the galaxy's bulge in the brightly coloured centre. The luminous, elongat...
Physics and Astronomy |Because these deposits carry information about early Earth’s surface conditions and climate changes, as well as provide much of modern industry’s iron resources, interested researchers have cast a wid...
Earth Sciences |An upgrade to a Cray XT5 high-performance computing system deployed by the Department of Energy has made the “Jaguar” supercomputer the world’s fastest. Located at Oak Ridge National Laboratory, Jagua...
