Pinpointing the cause of a neurodegenerative disorder

...ormal action. "Importantly, such insights can now guide studies that focus on the normal function and interactions of these proteins and how they might be enhanced by disease-causing mutations," said Zoghbi. "These studies could give better understanding of how the proteins cause disease." ...

Gambling monkeys give insight into neural machinery of risk

...t's more, said Platt, the studies with monkeys can guide studies in mice, in which scientists can make genetic alterations in the mice and study the behavioral effects of those alterations. Such studies could contribute to understanding of the genetic basis of compulsive behaviors and other such behavioral...

Drug resistance testing in treatment-naive HIV patients is cost-effective

...osis--before treatment is started--can effectively guide a physician's choice of treatment regimen and increase a patient's quality-adjusted life expectancy. (Quality-adjusted measurements of time reflect that survival with an illness is presumed to be of lower quality than healthy survival.) "For the ap...

MERIS monitoring tracks planetary photosynthesis levels

...tter are essential to assess environmental trends, guide policy making and support sustainable development. "Considerable efforts are made to evaluate the quality of the MGVI and comparable products," explains Gobron. "This takes place both through inter-comparisons between the products generated by vari...

New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

...tudy was to gather data on mouse models that could guide the safe application of the technique in human patients with, or at risk of, type 1 diabetes. Results of this study suggest that the MRI-MNP imaging technology may be helpful in identifying people at immediate risk of developing autoimmune diabete...

Researchers find molecule that inhibits regrowth of spinal nerve cells

...hrows up "fences" that repel developing nerves and guide them along the pathways to their appropriate connections to muscles. In 2002 Dr. Mark Henkemeyer, associate professor in the Center for Developmental Biology and of cell biology and one of the authors of the PNAS study, found that such a "fence" is ...

Gradient guides nerve growth down spinal cord

...mical signals known as the Wnt proteins acted as a guide for sensory nerves. These nerves have a receptor o...tem regeneration. If Wnt proteins could be used to guide transplanted nerve cells -- or someday, embryonic stem cells -- to restore the connections between t...

Evolution of life on Earth may hold key to finding life in outer space

...ed. The results of this type of research also help guide the search for life elsewhere in the universe, which is an important NASA objective." The goal of Fox's grant ?"The Origins of Translation and Early Evolution of Life" ?is to understand when and how the ribosome (or cellular protein synthesis machin...

NYU biologists map out early stages of embryo formation

...an 1,000 genes to coordinate the early events that guide the development of the animal. The results further suggest specific roles for new genes that had not been studied before, and functional tests of a subset of these supported the predictions. Describing how embryos function at the molecular level may...

Environment, not genes, key in family relationships

... implication," he continued. "But they should help guide future research into the important question of how children's genes help shape family interaction systems." ...

Researchers discover key to human embryonic stem-cell potential

... into, say, liver or brain tissue. But in order to guide them out of pluripotency with efficiency, we need to know what keeps them there to begin with. Researchers in the Whitehead laboratories of Young, Rudolf Jaenisch, MIT-computer scientist David Gifford, and the Harvard lab of Douglas Melton focused ...

Scientists and engineers apply nature's design to human problems

...terials and processes. "Biology can be a powerful guide to understanding problems in design and engineering," said Associate Professor of Biology Marc Weissburg, CBID co-director. "In comparative physiology, we teach that every animal has to solve a particular problem to survive, so every animal is a desi...

California computer scientists double volume of data in NIH biotech repository

...hers can use these reference data sets as tools to guide their own studies into the genetic basis of common diseases. To that end, the team's next collaboration with NCBI researchers will be to help design disease-association studies. "If a researcher is interested in a specific gene, we can use all the...

U-M scientists say fused genes trigger the development of prostate cancer

To that end, the team's next collaboration with NCBI researchers will be to help design disease-association studies. "If a researcher is interested in a specific gene, we can use all the...

Einstein scientists discover how protein crucial for motion is synthesised at the right place in the cell

...Not only does ZBP1 bind to actin messenger RNA and guide it to the cell's periphery, but it also helps regulate where in the cell the messenger RNA is translated into actin. "The ZBP1 bound to actin's messenger RNA acts like a lock to prevent it from being translated into protein before reaching its des...

Magnetic probe successfully tracks implanted cells in cancer patients

Marine conservation organizations team up to conduct Indonesia coral reefs assessment

... to the coral reefs from the tsunami and therefore guide management decisions to assist their natural recovery," said Capt. Philip Renaud, USN (Ret.), Executive Director of the Khaled bin Sultan Living Oceans Foundation. "It is a notable accomplishment that three marine conservation organizations ? the Kh...

Researchers know what you were about to say; fMRI used to detect memory storage and retrieval

...s disease and epilepsy. This knowledge could also guide creation of more self-sufficient artificial neural networks and robots. The study also broke new ground in how fMRI could be used to study how brain activity changes from second to second. Polyn and his Princeton colleagues gave participants 90 th...

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

The Government of Indonesia is leading the co-ordination and guiding all efforts to help fishing communities, supported and assisted by the UN Food and Agriculture Organization. Says WorldFish: "If necessary, donor agenc...

Scientists map one of biology's critical light-sensing structures

...ngs of how plants, fungi and bacteria use light to guide their development. It will likely spur a rush by scientists to capitalize on the new knowledge and may one day lead to such things as plants whose growth, flowering and death can be precisely manipulated. "We can now start changing how phytochromes...
