Stimulation of the semicircular canals can artificially control human walking and balance

... of Current Biology, published by Cell Press. To investigate how the body's ability to sense head movements can contribute to balance control and guidance control--two critical aspects of bipedal locomotion--the researchers stimulated nerves that normally communicate signals from the so-called semicircular can...

Adult stem cell research at UB targets damaged hearts

...illion grant from National Institutes of Health to investigate the potential of bone marrow-derived adult stem ce... Lee and colleagues will use the swine model to investigate whether transplanting the model's own bone marrow mesenchymal stem cells (MSC) -- cells that have th...

Large dinosaurs were extremely hot in their day, UF study finds

... In the meantime, the research team continues to investigate what are proving to be universal relationships among size, growth rate and temperature. "There are differences between mammals and invertebrates, but within a group, from a mouse to an elephant, or plankton to a large fish, we have found growth rat...

Higher risk for cervical cancer seen among women infected with multiple HPV types

...tudy using multiple measurements longitudinally to investigate the relationship between multiple HPV types and a woman's risk for developing pre-cancerous abnormalities in her cervix. During each of the 16,000 patient visits, both the pap smear and HPV tests were administered. The mean follow-up time of the stud...

Speeding the search for elusive chromosomal errors

...cent of the cases. He also has received a grant to investigate chromosomal rearrangements in bipolar disease, a complex disorder thought to involve interactions among multiple genes. Dr. Shaikh is currently collaborating with other researchers at Children's Hospital to evaluate other, higher-density gene chips ...

The higher the hierarchy, the greater the aggression

...dge), and Jeremy Field (University College London) investigate the extent to which differences in aggressive behavior within a cooperative society can be explained by "inheritance rank"--the likelihood that an individual will get to mate successfully in that society based on their rank--or place in the social hi...

Large-scale genomics project will hunt genes behind common childhood diseases

... to map gene variants to disease risk, but also to investigate how genes interact with environmental factors. "We will be tracing the major underlying genetic component of disease-related genes while discovering the biological pathways involved in disease development," Dr. Hakonarson added. "For instance, a sp...

New strategy developed to combat West Nile Virus

...y to understanding the spread of the disease is to investigate the local conditions that may lead to amplification. "It is a localized phenomenon," Shaman said. "We have to understand what goes on at the local level, at the appropriate scale, before we can reach the same conclusions that we found in southern Fl...

Common carp sheds new light on surviving in extreme environments

...ggerated and displayed so clearly. We now need to investigate whether the protein is involved in sustaining normal blood flow through tissue capillaries and oxygen delivery during difficult times." ...

Epstein-Barr virus might kick-start multiple sclerosis

... a postdoctoral fellow at NIH. He is continuing to investigate the role of Epstein-Barr virus in MS in the lab of...n the development of the disease. "Our aim was to investigate what causes these increased antibody concentrations and if T cell responses to EBV are different in ...

Researchers find that bumblebees' flower choice matters

...ing pollinators away from the native plants. To investigate her hunch further, Flanagan added a third wetland species to the garden ?a native plant known as "great blue lobelia." So far, the bees continue their strong attraction to purple loosestrife. "This preference for purple loosestrife or other exotics...

Scientists' cell discovery unearths evolutionary clues

...step for Professor Baldauf and her team will be to investigate the origin of these amoebas, and also to search for new species and to establish their position on the family tree. Meanwhile, a number of research projects, including teams in the USA and Germany, have won sponsorship to sequence the genomes of soci...

Stem cell expansion

...n some promise for stem cell expansion in mice. To investigate the potential of HOXB4 treatment for HSC expansion before transplantation in humans, Kiem and colleagues therefore turned to nonhuman primates, an established preclinical model for HSC transplantation and gene therapy. The team showed that HOXB4 o...

Tarantulas produce silk from their feet

...rets. The next step, according to Summers, is to investigate whether the silk produced by the feet is the same as that produced by the spinneret. Many spiders can produce seven different kinds of silk. Scientists will look at the genes involved in silk production from the feet, compare them to the gene family ...

High dopamine transporter levels not correlated with ADHD

...s among subjects, we designed the current study to investigate dopamine transporter levels in ADHD subjects and control subjects while excluding these potentially confounding factors," Wang said. The researchers measured dopamine transporter levels in 20 adult ADHD subjects who had never received medication, n...

Mayo Clinic collaboration mining of ancient herbal text leads to potential new anti-bacterial drug

...nologies to identify promising natural products to investigate as drugs for new and better therapies. "Natural products are invaluable sources of healing agents -- consider, for example, that aspirin derived originally from willow bark, and the molecular basis of the anti-cancer chemotherapeutic agent Taxol T...

A giant among minnows: Giant danio can keep growing

...e phase. Next step This model can be used to investigate muscle wasting diseases such as muscular dystrophy. Other studies have already shown that a condition similar to muscular dystrophy can be experimentally induced in zebrafish. One of the next steps for the researchers is to induce the condition in th...

Honey bee genome holds clues to social behavior

...00 genes. Statistical techniques were then used to investigate whether particular transcription factors correlated with genes that were differentially expressed (turned on or off) between nurse bees and foragers. "We found five different transcription factors that showed a statistically significant correlation...

Humpback whales have brain cells also found in humans

... complexity and as such, it would be compelling to investigate how many convergent cognitive and behavioral features result from largely dissimilar neocortical organization between the two orders." They also suggest that the current study provides a framework for further investigations into the brain and behavio...

Fruit fly aggression studies have relevance to humans, animals

...completely novel genes we can use in the future to investigate aggressive behavior," Mackay said. "Ultimately we hope to understand the basic biology of this very important trait, because the better we understand it in flies, the more we can develop logical human pharmaceutical interventions." ...
