Slow brain waves play key role in coordinating complex activity

... rapid firings accompany activity, neuroscientists think that information in the brain is carried by the hi...ain areas would show strong coupling. "We used to think that one little patch of cortex takes care of this function and another little patch takes care of t...

Brain regions do not communicate efficiently in adults with autism

...r major characteristics, of autism. UW colleagues think EEG techniques can be used on young children to help in the early detection of autism, which is critical in providing interventions for the disorder. Other members of the research team are from the UW's Autism Center and include Geraldine Dawson, ce...

Does natural selection drive the evolution of cancer?

...ays. "Evolution is going on in the tumor. So let's think about how we might want to influence that evolution. Can we push it down paths that might be more beneficial to us?" One idea might be to develop new drugs that would act as benign cell boosters. Such drugs would specifically target the more benig...

Scientists get best look ever at water-life connection

... it couldn't connect with the protein at all. So I think this is nature's way of getting the interaction just right." ...

Stanford discovery may help predict when toxoplasma can be deadly

...o hijack cellular processes in their hosts. "We think that the different versions of Toxoplasma strains evolved for optimal interaction with different hosts," said Boothroyd, noting that the wrong pairing of parasite and host can have dire consequences. "If a given strain gets into the 'wrong' host, ...

Fighting like a girl or boy determined by gene in fruit flies

...g model used. "We want to understand that. I can't think of a better system to study than fruit flies. And .... "That's a pretty big thing," Baker said. "We can think about understanding in molecular detail how we go from the initial genes and the proteins they encod...

New mechanism underlying pain found

...activity in both cardiac cells and neurons. "We think we have only scratched the surface in this area, as pacemaker channels may also play a role in inflammatory pain as well as other types, " said Dr. Wickenden. "More research is needed before this will translate to patient benefit, but the better unde...

UCSD researchers create roadmap to integrin activation

... targets along the pathway for new drugs. "If you think of these pathways as interstate highways on a map, this study now enables us to see other back roads that lead to the destination," said Ginsberg. Talin is also critical for activation of related integrins, such as those on white blood cells. In th...

Researchers barcode DNA of Venice museum's vast fungi collection

...nelli, director of the Musei Civici Veneziani. "We think that this is an exemplar model, to be followed in subsequent projects. Furthermore, in our philosophy, natural science collections are public goods that everybody belonging to the scientific community should be able to take advantage of." ...

Biofuel cells without the bio cells

...to a mineral using a purified protein, and I don't think anyone had shown that before," said Thomas Squier, senior author and lab fellow at the Department of Energy's Pacific Northwest National Laboratory. The feat is the bacterial equivalent of removing lungs and coaxing the disembodied tissue to breath...

Dragonfly's metabolic disease provides clues about human obesity

...id Marden. "Granted, it is a big extrapolation to think that our dragonfly results might have any relevance for human disease, but it would be irresponsible for us to not point out these possibilities. People who study metabolic disease should test the hypothesis that changes in gut microbial composition...

Proteins anchor memories in our brain

... lower levels of insulin in this organ. "What we think is that 'more is better' in the thymus," Anderson says. "If you have more insulin in the thymus, then there is a better chance that potentially destructive insulin-specific T cells will encounter insulin as self and be filtered out." In the thymu...

Cigarette smoking impedes tendon-to-bone healing

"If you have more insulin in the thymus, then there is a better chance that potentially destructive insulin-specific T cells will encounter insulin as self and be filtered out." In the thymu...

History-hunting geneticists can still follow familiar trail

...hondria for all kinds of work for 20 years, and to think that mtDNA didn't correlate with population size was clearly going against the dogma. This study shows the dogma is safe in mammals and probably in vertebrates, as well."...

Walking not enough for significant exercise benefits

...ercise program. "Our concern is that people might think what matters most is the total number of daily steps accumulated, and not pay much attention to the pace or effort invested in taking those steps," Dr. Harber said. "The 10,000-step or pedometer-based walking programs are great for people--they are m...

Gene chip technology shows potential for identifying life-threatening blood infection

...ick but did not have an infection," Cobb says. "We think this is an important first step to developing a similar test for human patients." Nine of these genes turned out to be common responders to inflammation and infection in mice. Some of these genes also have been identified by other scientists study...

Coral reefs are increasingly vulnerable to angry oceans

...eneration of corals. "Regardless of whether we think of more severe storms as a looming threat or just the ramping up of a natural cycle, one thing is certain," said Connolly. "To predict how coral reefs will look under different future scenarios, and to plan accordingly, we needed to know exactly how...

Dinosaurs -- stones did not help with digestion

...e found together with sauropod skeletons, we don't think they are remains of a gastric mill such as occurs in birds,' Dr. Sander comments. In that kind of gastric mill the stones would have been very worn and would not have a smoothly polished surface. Apart from that, gastric stones are not discovered reg...

Wolves are suffering less from inbreeding than expected

...aintained longer than previously estimated. - We think our results are relevant also for other threatened populations of carnivores. Such spe cies require large areas for their territories and most natural reserves are of a size in which only a few territories can be accommodated. Without immigration inb...
