St. Jude study solves mystery of mammalian ears

...f St. Jude is that researchers have the ability to ask some very basic questions about how the body works, and then use those answers to solve medical problems in the future.” The long-standing argument centers around outer hair cells, which are rod-shaped cells that respond to sound waves. Located in ...

Modeling the restless brain

...tivity to cognitive and behavioral performance and ask questions about differences in the brains of individual persons. Sporns said this research could lead to clinical applications, offering new diagnostic tools for brain disorders such as Alzheimer's disease that are known to affect the brain's con...

MU researchers to study the status of black bears in Missouri

...ct their property. This pilot study should help us ask better research questions down the road. We don’t know if we have a self-sustaining population in Missouri or if we simply have a lot of dispersing males coming from Arkansas. We need to investigate the genetic interchange between the two populations...

The mouflons of the Kerguelen archipelago

...itnessing a loss of biodiversity. While scientists ask themselves about our impact on the genetic diversity of populations, this study by Denis Réale and his co-workers sheds new light on mechanisms that can regulate this genetic diversity. ...

Putting feelings into words produces therapeutic effects in the brain

...g their feelings into words is helpful. “If you ask people who are really sad why they are writing in a journal, they are not likely to say it’s because they think this is a way to make themselves feel better,” Lieberman said. “People don’t do this to intentionally overcome their negative feelings; it...

DOE JGI sets 'gold standard' for metagenomic data analysis

...ity can not only compare the methods, but can also ask the question, why is this method better, or why does this one fail. Over all, we hope that it will help to improve the process and lead to further development of new methods for evaluating metagenomes, particularly since this gold rush is not going a...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

...irming that flies lost sleep when infected, was to ask the converse: when sleep is disrupted, does that affect immunity" The challenge was how to disrupt the flies' sleep. Schneider tried building a machine that jostled the flies randomly. "All it was really good at doing was throwing the tubes around...

Do fruit flies have free will?

...posed the wrong way," says Brembs. "Instead, if we ask 'how close to free will are we"' one finds that this is precisely where humans and animals differ". The next step will be to use genetics to localize and understand the brain circuits responsible for the spontaneous behavior. This step could lead ...

Peanut allergies overstated, study finds

... "If there is a positive result, people need to ask whether it might be worth a peanut challenge in a hospital environment, especially if their child has never had an allergic reaction to peanut before," Dr Wainstein said. ...

Fast and slow -- How the spinal cord controls the speed of movement

...dy. "Now that we know the pattern, we can begin to ask how that changes in disease states." David McLean, Cornell postdoctoral researcher in Fetcho’s laboratory, was the first person to discover the pattern of neural activation and how it was associated with speed of movement. He is the lead author on ...

MIT's ocean model captures diversity of underwater forests

...e beginning," said Chisholm. "Now we can begin to ask the model questions and test hypotheses about the role of oceanic microbes in global processes. This will help guide decisions about responsible use of the oceans in this era of global change." ...

A 'traffic light' for neurons means 'go' for improving brain research

...f Würzburg in Germany. "This gives us the power to ask what the causal role of specific cell types is in neural circuit function." Knowing the effects that different neurons have could ultimately help researchers figure out the workings of healthy and unhealthy brain circuits, explains graduate studen...

Researchers learn what sparks plant growth

...hory. "It took us 10 years to develop the tools to ask the question. It is very satisfying for me to see the results." Roots and shoots are a plant’s two major organ systems. For this study, published in the March 8, 2007, issue of the journal Nature, the scientists examined shoots and the three layer...

OHSU surgeon implants donated tissue allografts

OHSU physicians are involved in several trials to assess the efficacy of these treatments and continue to pioneer cartilage surgery treatments. ...

Research finds music training 'tunes' human auditory system

...ences and disorders. "Our study is the first to ask whether enhancing the sound environment -- in this case with musical training -- will positively affect the way an individual encodes sound even at a level as basic as the brainstem," says Patrick Wong, primary author of "Musical Experience Shapes Hu...

Anxiety disorders surprisingly common yet often untreated

...disorders for physician follow-up. These questions ask the patient if he or she has felt nervous or has been unable to stop or control worrying over the previous two weeks. Bringing this information to the physician’s attention is important because the doctor may be focused on the patient’s physical com...

New technologies coming too fast for Indian farmers

...rmers can't properly evaluate seeds. Instead, they ask their neighbors. Copying your neighbor isn't necessarily a bad thing; but in this case, everyone is copying everyone else, which results in fads, not testing." Stone argues that the previously undocumented pattern of fads, in which each village moves...

Scientists map key landmarks in human genome

...nucleosomes, and that led us to devise a method to ask where the nucleosomes are located." The researchers used gene microarrays to which DNA associated with single nucleosomes was added. The nucleosomal DNA was derived from several cancer cell lines including melanoma and breast cancer, as well as se...

No-scalpel vasectomies by skilled surgeons may speed recovery

... that a patient considering a no-scalpel vasectomy ask his doctor where he received his training and how many of these surgeries he has done. More studies would help: "Informed patients will benefit from data showing that it is a technique associated with less pain and fewer complications." ...
