DURHAM, NC – Duke University bioengineers have developed a new method for rapidly producing an almost unlimited variety of man-made DNA sequences. These novel sequences of recombinant DNA are used to produce repetitive proteins to create new types of drugs and bioengineered tissues. Current methods for producing these DNA sequences are slow or not robust, the researchers said, which has hindered the development of these increasingly important new classes of protein-based polymers. Researchers have already demonstrated that when a large protective macromolecule – known ...

Surgery has not been an option in the past for children with ACL tears because of the possible damage to the growth plate that can cause serious problems later in life. With this new technology, surgeons can actually see from one point to the other on either side of the knee, and can safely position the tunnels where they will place the new ligament. John Xerogeanes, MD, chief of the Emory Sports Medicine Center, and colleagues in the laboratory of Allen R. Tannenbaum, PhD, professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and ...

WASHINGTON, DC, January 25, 2011 – The tiger reserves of Asia could support more than 10,000 wild tigers – three times the current number – if they are managed as large-scale landscapes that allow for connectivity between core breeding sites, a new paper from some of the world's leading conservation scientists finds. The study, co-authored by World Wildlife Fund (WWF) scientists, is the first assessment of the political commitment made by all 13 tiger range countries at November's historic tiger summit to double the tiger population across Asia by 2022. "A Landscape-Based ...

A study by researchers at Washington University School of Medicine in St. Louis has raised safety concerns about an investigational approach to treating cancer. The strategy takes aim at a key signaling pathway, called Notch, involved in forming new blood vessels that feed tumor growth. When researchers targeted the Notch1 signaling pathway in mice, the animals developed vascular tumors, primarily in the liver, which led to massive hemorrhages that caused their death. Their findings are reported online Jan. 25 in the Journal of Clinical Investigation and will appear ...

WEST LAFAYETTE, Ind. - Researchers have invented a technique that uses inexpensive paper to make "microfluidic" devices for rapid medical diagnostics and chemical analysis. The innovation represents a way to enhance commercially available diagnostic devices that use paper-strip assays like those that test for diabetes and pregnancy. "With current systems that use paper test strips you can measure things like pH or blood sugar, but you can't perform more complex chemical assays," said Babak Ziaie, a Purdue University professor of electrical and computer engineering and ...

Washington, D.C. (January 25, 2011) -- In a development that may revolutionize handheld electronics, flat-panel displays, touch panels, electronic ink, and solar cells, as well as drastically reduce their manufacturing costs, physicists in Iran have created a spintronic device based on "armchair" graphene nanoribbons. Spintronic devices are being pursued by the semiconductor and electronics industries because they promise to be smaller, more versatile, and much faster than today's electronics. As described in the American Institute of Physics journal Applied Physics Letters, ...

CHESTNUT HILL, MA (1/25/11) -- Researchers from Boston College, MIT, Clemson and Virginia have used nanotechnology to achieve a 60-90 percent increase in the thermoelectric figure of merit of p-type half-Heusler, a common bulk semiconductor compound, the team reported in the American Chemical Society journal Nano Letters. The dramatic increase in the figure of merit, used to measure a material's relative thermoelectric performance, could pave the way for a new generation of products – from car exhaust systems and power plants to solar power technology – that that runs ...

Washington, D.C. (January 25, 2011) -- A team of physicists has taken a big step toward the development of useful graphene spintronic devices. The physicists, from the City University of Hong Kong and the University of Science and Technology of China, present their findings in the American Institute of Physics' Applied Physics Letters. Graphene, a two-dimensional crystalline form of carbon, is being touted as a sort of "Holy Grail" of materials. It boasts properties such as a breaking strength 200 times greater than steel and, of great interest to the semiconductor and ...

NASA's Aqua satellite captured an infrared image of the very cold clouds that house powerful thunderstorms within the Southern Indian Ocean's newest tropical depression, number 10S. The depression quickly strengthened into a tropical storm and continues to affect the northern coast of Western Australia. When Aqua passed over the Tropical Storm 10S on January 25 at 05:53 UTC (12:53 a.m. EST), the Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of the storm's clouds. The image showed that most of the coldest cloud tops (-63 Fahrenheit/-52 Celsius) ...

Wilma caught the eye of NASA. NASA's Aqua satellite captured visible and infrared images of Cyclone Wilma in the Southwestern Pacific Ocean and her eye was clearly visible from space. On January 25 at 00:59 UTC (8:59 p.m. EST on Jan. 24), the Atmospheric Infrared Sounder (AIRS) instrument captured data that was used to create infrared and visible images at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The images showed Cyclone Wilma had strengthened overnight and now has a visible eye. AIRS Infrared imagery showed strong, very cold thunderstorm cloud tops around ...

SEATTLE – Women who have experienced hot flushes and other symptoms of menopause may have a 50 percent lower risk of developing the most common forms of breast cancer than postmenopausal women who have never had such symptoms, according to a recent study by researchers at Fred Hutchinson Cancer Research Center. The results of the first study to examine the relationship between menopausal symptoms and breast cancer risk are available online ahead of the February print issue of Cancer Epidemiology Biomarkers and Prevention. The protective effect appeared to increase along ...

Charles Darwin based his groundbreaking theory of natural selection on the realization that genetic variation among organisms is the key to evolution. Some individuals are better adapted to a given environment than others, making them more likely to survive and pass on their genes to future generations. But exactly how nature creates variation in the first place still poses somewhat of a puzzle to evolutionary biologists. Now, Joanna Masel, associate professor in the UA's department of ecology and evolutionary biology, and postdoctoral fellow Etienne Rajon discovered ...

Measuring the attractive forces between atoms and surfaces with unprecedented precision, University of Arizona physicists have produced data that could refine our understanding of the structure of atoms and improve nanotechnology. The discovery has been published in the journal Physical Review Letters. Van der Waals forces are fundamental for chemistry, biology and physics. However, they are among the weakest known chemical interactions, so they are notoriously hard to study. This force is so weak that it is hard to notice in everyday life. But delve into the world of ...

In an effort to better understand the dynamics of complex networks, scientists have developed a mathematical model to describe interactions within ecological food webs. This research, performed by Northwestern University physics professor Adilson Motter and his student, Sagar Sahasrabudhe, is published in the January 25 issue of Nature Communications. The work illustrates how human intervention may effectively aid species conservation efforts. "Our study provides a theoretical basis for management efforts that would aim to mitigate extinction cascades in food web networks. ...
