Flavanols in cocoa may offer benefits to the brain

...a flavanols for more than 15 years. “The findings raise the possibility that products utilizing this cocoa could be developed to help maintain healthy brain function throughout several life stages. More research examining the potential of this cocoa in this important area of public health need is clearly...

Living with water scarcity -- world must act now

... of poor people by focusing on water as a means to raise their own food and gain more income. Growing more food with less water ?increasing water productivity ?can reduce future demand for water, thus easing competition for water and environmental degradation. A 35% increase in water productivity coul...

Bumblebee house warming -- it takes a village

...an fanning because the researchers did not want to raise the temperature too high. Excessive heat can kill bumblebees. In looking at the incubation behavior, O'Donnell said workers vibrate wing muscles to shunt down heat to their abdomen, which is held in close contact with a comb containing the brood. ...

Boosting brain power -- with chocolate

...he biggest scientific conferences in America, also raise the prospect of ingredients in chocolate being used to treat vascular impairment, including dementia and strokes, and thus for maintaining cardiovascular health. The study also suggests that the cocoa flavanols found in chocolate could be useful i...

Salamanders suffer delayed effects of common herbicide

...ogists who say findings from their long-term study raise concerns over the role of atrazine in global amphibian declines. The results also suggest that while impacts of the herbicide, atrazine, may not show up in short-term studies, even extremely low concentrations of the chemical may be deadly to amphib...

Fish can determine their social rank by observation alone, study finds

...ves them valuable time and energy." The results raise the possibility that fish brains might contain the rudimentary neuronal circuitry for transitive inference that appeared later in birds and mammals. "Any animal that has evolved a social system that requires combat among males will have some kind...

Salmon farms kill wild fish, study shows

...ited States of America. "We know that fish farms raise sea lice levels, and we know that sea lice kill fish," said the study's lead author Martin Krkosek, a Ph.D. student at the University of Alberta Centre for Mathematical Biology. "This is the first study to combine field surveys, experiments and mathe...

New study finds chocolate chip cookies lower cholesterol

...teins, those that were smallest and most likely to raise risk for heart disease. Body weight did not change and there were no changes in HDL (good) cholesterol. According to the Center for Disease Control, a 10 percent decrease in total cholesterol levels may result in an estimated 30 percent reduction in...

Gene therapy inhibits epilepsy in animals

...r an injury such as severe head trauma is known to raise the risk of later developing epilepsy, so this study suggests that strategies aimed at modifying signaling pathways in the brain after such an insult may help prevent epilepsy," said Dr. Brooks-Kayal. "The approach would likely be different than in t...

Vaccination with embryonic stem cells prevents lung cancer in mice

...arcinogens that cause lung cancer. "Our results raise the exciting possibility of developing a prophylactic vaccine capable of preventing the appearance of various types of cancers in humans, especially those with hereditary, chronological or environmental predispositions to neoplastic disease." Howe...

Novel pathway regulates timing of brain cell development

...s pathology, the researchers note. "Our findings raise the intriguing possibility that defects in presenilin-mediated erbB4 signaling could be implicated in the early stages of Alzheimer's disease," Corfas says. "Further studies of erbB4 nuclear signaling could provide important insights into the causes ...

Molecules in blood foretell development of preeclampsia

...uce a form of VEGF. Presumably, such a drug would raise the levels of circulating VEGF in the bloodstream. The surplus VEGF would bind to the high levels of sFlt1 produced during preeclampsia, but enough free VEGF would still be available to attach to cell surface receptors to promote the health of blood...

Gene-bender proteins may sway to DNA

...e protein that bends the DNA. She said the results raise important questions about the role that the DNA "bendability" plays in guiding the correct bending protein to the appropriate site on the DNA. Ansari said the research adds to the basic understanding of how proteins recognize a specific binding si...

End of deforestation in view? Experts advance new way to size up global forest resources

...osperity and measures such as good governance that raise income need not shrink forests, according to the paper. Forest "transitions" While forest density data are relatively new, forest area data spanning 200 years show several places worldwide have shifted from net deforestation to net reforestatio...

Rising ocean temperatures, pollution have oysters in hot water

...as the water temperature rose. Warmer temperatures raise the oyster's metabolic rate, which raises its oxygen and energy requirements, Lannig explained. In addition, oysters exposed to cadmium at 20°C and 24°C needed more oxygen than the oysters in their groups not exposed to cadmium. That makes sense, ...

Developing uses for sugar-cane bagasse: Biotechnology applied to the paper industry

...of the substrate to be processed and, in this way, raise the profitability of the operation. Furthermore, this process can be adapted to the processing of other raw materials (wood, cereals). Investigation of the use of methanol as laccase inducer can, similarly, be envisaged as a way of recycling this com...

Most important actors in the growth process of neurons identified

Given that this research can raise a lot of questions for patients, we ask you to please refer questions in your report or article to the email address that VIB makes available for this purpose: patienteninfo@vib.be . Everyone can submit questions concerning this and other medically-...

Neural stem cells lend the brain a surprising capacity for self-repair

...ms are still being worked upon, these observations raise the possibility that postnatal neurogenesis can one day be used to repair brain damage," the researchers concluded. "Our results here show that self-repair and local remodeling can indeed happen along the brain's lateral ventricular wall, and furt...

Common cold virus leads to death in lung transplant patients

...COPD." They continued: "These exciting new data raise the possibility that patients with asthma and other patients with chronic airway disease are unusually susceptible to rhinovirus infection leading to increased rates of exacerbation. These results may also help explained the increased susceptibility ...

West Australian fossil find rewrites land mammal evolution

...' Mr Fitzgerald said. "The fossils of Gogonasus raise the possibility that tetrapods originated not in the northern hemisphere, as is widely thought, but in Gondwana, the ancient southern super-continent, and more specifically Australia. But further discoveries of fossils in Australia are needed to conf...
