Cellulosic ethanol: Fuel of the future?

...ls by 2017 ''is very substantive, but Bush did not provide any insights into what he is going to do to make that happen,'' Somerville said, adding that it will take seven to 10 years to produce cellulosic ethanol at competitive prices. ''It is certainly possible to achieve Bush's goals technically,'' he s...

Swell gel could bring relief to back pain sufferers

...eve injections of tiny sponge-like particles could provide an alternative to major surgery in the treatment of chronic lower back pain. Dr Brian Saunders from The School of Materials and Professor Tony Freemont from The Faculty of Medical and Human Sciences have developed tiny gel particles that swell and s...

Penn researchers replace organ in adult mice using 'single-parent' stem cells

Stopping plants from getting sick

...t ability and block infection. "These pathogens provide us with the best of both worlds in terms of research ?we can study them in the field, but we can also bring them to the laboratory and isolate the genes that allow them to infect the plant," says Kronstad. "In fact, genomics and computers have made t...

Study uncovers a lethal secret of 1918 influenza virus

... to trigger such a devastating immune response may provide biomedical researchers with clues about how to intervene and stop or mitigate the virus' potentially lethal effects, Kawaoka says. "Things may be happening at an early time point (in infection), but we may be able to step in and stop that reaction...

The origin of the brain lies in a worm

...rom their remote common ancestors." The findings provide strong evidence for a theory that was first put forward by zoologist Anton Dohrn in 1875. It states that vertebrate and annelid CNS are of common descent and vertebrates have turned themselves upside down throughout the course of evolution. "This e...

Parasite infection may benefit MS patients

...tients. The authors suggest that their findings provide evidence to support that an autoimmune response as a result of parasite infection can result in a decrease in the normal inflammatory response associated with MS. They note that evidence for production of regulatory T cells (which inhibit the immune ...

Health Canada approves cold and flu medicine

...entative medicine. Second, COLD-fX can be taken to provide symptom relief for colds and flu." Shan added that Health Canada reviewed all of CV Technologies published and unpublished data on COLD-fx before approving the claims. The NHPD issues product licenses in several categories. Because COLD-fX® is...

New sensor detects gaseous chemical weapon surrogates in 45 seconds

...lengths between three and 12 micrometers, and QCLs provide access to any wavelength in this region. "Because of this access and the fact that QPAS is almost immune to acoustic interference, we have potential for extraordinary chemical sensitivity and selectivity," Wojcik said. QPAS's small components r...

Scientists unlock mystery of embryonic stem cell signaling pathway

... because it is currently the only proven method to provide the stem cells with the necessary chemical signals that prompt them to stay undifferentiated and to continue dividing over and over. Still, growing human embryonic stem cells on a layer of mouse fibroblasts has never made much sense to the scienti...

Long-lived deep-sea fishes imperiled by technology, overfishing

...replenish themselves. And the habitat that used to provide them protection ?the deep ocean ?is now accessible to fishing because of new technologies." Among the most recognized deep-sea species at-risk are orange roughy and Patagonian toothfish, better known as Chilean sea bass. In the deep ocean off the ...

Biologists produce global map of plant biodiversity

Statin plus cancer drug deliver combo punch to brain cancer cells

...owerful cell-survival signal, and lovastatin could provide the added boost necessary to kill more cancer cells." Specifically, Eberhart found links between the expression of key hedgehog-related genes in medulloblastoma cells and another cell signal already tied to cancer, Bcl-2. Eberhart and his team bel...

Scientists identify a gene that may suppress colorectal cancer

...anding of the biological function of ATP5A1 will provide insights concerning its potential role in human cancer.? Colorectal cancer is currently ranked as the second leading cause of cancer death in the United States. But scientific progress in cancer research is challenged by the array of environmental...

New test for most virulent HPV strains under study

...the HPV vaccines, hopes the new tests will one day provide better options for screening for the most common sexually transmitted disease. The current national study is giving the new HPV test and the type-specific assay to 1,500 women age 30 and older with a negative Pap test and to 1,000 women age 18 and...

Primitive yeast yields secrets of human cholesterol and drug metabolism

Mother knows best: Plant knowledge key to childhood health in remote Amazon

...obs in emerging markets devalue folk knowledge and provide access to products not made from local resources, but without providing adequate medical treatment substitutes," said Reyes-García. "In a situation where local medicinal knowledge is not adequately substituted by access to medical facilities, the con...

Conceptualizing a cyborg

...a is to use regions of undamaged nervous tissue to provide command signals to drive a device, such as an artificial limb. The challenge is for a prosthesis to perform naturally, relaying two-way communication with the patient's brain. For example, the patient's thoughts could convert nerve signals into move...

Quitting smoking reduces risk of lung cancer mortality by 70 percent

The Collaboration's primary goal is to provide direct, reliable evidence about the determinants of stroke, coronary heart disease, and other common causes of death in Asia-Pacific populations. It aims to produce region-, age- and sex-specific estimates of the cardiovascular disease risks associa...

Stem cell identity in culture may strongly depend on the cellular microenvironment

...med attribute of the cells. In practice, this work provide a rationale to research strategies that aim to increase the efficiency of stem cell-related culture methods and, perhaps, even to develop stem cells from already differentiated cells instead of using embryos. ...
