Research finds music training 'tunes' human auditory system

...ding new lines of inquiry. The researchers now are looking to find ways to "train" the brain to better encode sound ?work that potentially has far-reaching educational and clinical implications. The study was supported by Northwestern University, grants from the National Institutes of Health and a grant from...

NASA predicts nongreen plants on other planets

...t with the different types of stars they orbit. By looking at the changes in that light through different atmospheres, researchers identified colors that would be most favorable for photosynthesis on other planets. This new research narrows the range of colors that scientists would expect to see when pho...

Cold sore virus might play role in Alzheimer's disease

Antifungal drug kills TB bug

...ew targets for antibiotic drugs. "When we began looking at the bug and its DNA content in more detail, we noticed it had some unusual characteristics. In particular, we noted the presence of a very large number of enzymes called P450s, which are usually associated with more complex organisms. "In human...

New mechanism for nutrient uptake discovered

...They have found a site for phosphorylation and are looking at this possibility further. A leading expert in transporters, Professor Dale Sanders, head of the biology department at the University of York in the U.K. commenting on the work said: "Loqué, Frommer and co-workers have demonstrated very beauti...

Iowa State University botanists identify new species of North American bamboo

...s, especially birds." Clark and Triplett began looking at the North American bamboos as part of a larger collaboration with botanists worldwide to develop an evolutionary family tree of bamboo species. They're using modern DNA sequencing technologies together with traditional plant taxonomy, which involv...

Wheat can fatally starve insect predators

...and reproduction." The scientists currently are looking for regulatory regions in Hessian fly-susceptible wheat genes that might act as vehicles to carry lectin or a toxin into plants to halt the virulent insects, Williams said. The regulatory regions, or promoters, would be from genes that the fly larvae...

Darwin's famous finches and Venter's marine microbes

...en in specific human kinases. Says Manning, "By looking at all these very distant microbial relatives we can understand more even about human kinases and their relationship to cancer and other diseases. We go out into the ocean, we find all this diversity and analyzing what’s new and what’s not new reflec...

World's largest flower evolved from family of much tinier blooms

...try, the scientists delved deeper into the genome, looking at some 11,500 base pairs of DNA to determine that the giant flower's closest relatives are in the Euphorbiaceae family, many of which have blossoms just a few millimeters in diameter. "The power of nucleic acid comparisons is revealed as well as e...

Large size crucial for Amazon forest reserves

...tand real species occurrence", said Nichols, "and looking at occurrence through time, one understands the dynamics of species faced by forest destruction". Some vanish because they don't survive in a given site, others because they don't colonize new sites that become available. The two processes may also a...

Racing neurons control whether we stop or go

New species declared: Clouded leopard on Borneo and Sumatra

... its spots? For over a hundred years we have been looking at this animal and never realized it was unique,?said Adam Tomasek, head of WWF’s Borneo and Sumatra program. “The fact that Borneo’s top predator is now considered a separate species further emphasizes the uniqueness of the island and the importance...

Researchers first to map gene that regulates adult stem cell growth

...lt of trauma or stroke. The researchers also are looking into the possible role the gene plays in transforming healthy stem cells into cancerous ones, such as in leukemia and lymphomas. If the gene does in fact play such a role, it is possible that it also could provide the keys to new therapies. Van Zan...

Scientists find new genetic clue to cause of Alzheimer's disease

...group of proteins that transport APP within cells, looking for small changes, or "misspellings," in seven genes involved in moving APP within cells. To start, the scientists combed two large data sets of genetic information from families in which more than one person has Alzheimer's disease. They were soo...

Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward

... ecosystems." Lyons sees what is happening now looking similar to what existed during the Eemian warming period ?a time 130,000 years ago before the last major glacial stage. "We know that the climate was warmer then, sea levels were higher by a couple of meters compared to today. Lyons points to the...

Growth hormone is not the anti-aging bullet for healthy adults

...000 per month to $2,000 per month. "Everyone is looking for the fountain of youth," Liu said. "We wanted to see if there is any validity behind some of the claims made about growth hormone's anti-aging properties. "Our biggest surprise was the general lack of research that had been done in this area. ...

Scientists map key landmarks in human genome

Applied scientists create wrinkled 'skin' on polymers

...us directions," says Vaziri. "At the moment we are looking at the effect of ion beam energy and have been able to reduce the wavelength of the wrinkles to 50 nanometers. Manipulation at such a small scale makes this method even more attractive. We are also building multifunctional microfluidic devices for th...

Mosquito repellents that emit high-pitched sounds don't prevent bites

...Cochrane Researchers conducted a systematic review looking for trials conducted with EMRs. They located ten field trials that had been carried out in various parts of the world. None of these trials showed any evidence that EMRs work. "All ten studies found that there was no difference in the number of mo...
