Molecule does more than slice and dice RNA

...ar ruler," Doudna explained. "It gives us a lot of insight into how the mechanism works." Dicer, which is ubiquitous in the cells of higher animals, including humans, is a widely studied molecule. It was first discovered in 2001 by Gregory J. Hannon, an HHMI investigator at Cold Spring Harbor Laboratory, an...

Researchers identify new cord blood stem cell

...d by this discovery because it provides additional insight into how stem cells can restore function in the brain after injury," said Walter Low, Ph.D., senior investigator of the study, and professor of Neurosurgery and the Stem Cell Institute at the University of Minnesota. This research was published in ...

Single microRNA causes cancer in transgenic mouse

... to cause cancer in mice. The discovery offers new insight into the development of some forms of leukemia and lymphoma and at the same time underscores the powerful role that these tiny snippets of non-coding RNA play in cell signaling pathways active in carcinogenesis. "To the best of our knowledge, this ...

Chemical guidance of T cells leads to immunologic memory and long-term immunity

...generation. These new findings not only provide insight into the fundamental behavior of the immune system, but also suggest that attention needs to be paid to chemokines and chemokine receptor function when designing new vaccine strategies and evaluating whether drugs targeting chemokines might have unan...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...ment, and is therefore likely to provide important insight into human development. "Biased left-right asymmetry is both a fascinating and medically important phenomenon," said Levin. "Problems with left/right asymmetry are responsible for a wide-range of birth defects in humans including conditions that affe...

How 'hot' emotional brain interferes with 'cool' processing

...Duke University Medical Center researchers provide insight into the basic brain mechanisms responsible for the distraction caused by emotional stimuli that are irrelevant to a task. Moreover, they said, the findings offer a new approach to understanding how people with depression and post-traumatic stress di...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

...s are having on the environment, as well as permit insight into the evolution of life on Earth. The UCSD Divi..., analysis of the marine genome data will allow us insight into natural marine products and how they can be applied for pharmacy and medicine," said Wooley, th...

Protein translation in sperm

... 15th issue of Genes & Development lends novel insight into the cellular changes that occur in sperm while they reside in the female reproductive tract ?providing a new understanding of the molecular genetics of successful fertilization. It had been believed for decades that spermatozoa are translationa...

Ancient DNA provides clues to the evolution of social behavior

...odent's survival, Hadly asserts, and could provide insight into the evolution of social behavior in other animals, including ants and humans. Population crash Named for the ''tuc-tuc-tuc'' sound of its call, the colonial tuco-tuco (Ctenomys sociabilis) lives in remote highland savannah areas of southern ...

Ticks, flukes, and genomics: Emerging pathogens revealed

...mpared. With this final analysis, they gleaned new insight into the broader tactics used by different bacteria. Ehrlichiosis pathogens, for instance, appear capable of making vitamins that a host tick lacks in its regular diet. "This study is a beautiful example of how in-depth comparative genomics can lea...

Darkness unveils vital metabolic fuel switch between sugar and fat

... Nature. While their findings could provide new insight into mammalian hibernation, researchers note that the pivotal metabolic signal that emerged from the dark also presents a new target for obesity and type 2 diabetes research. A series of experiments pinpointed 5-prime adenosine monophosphate (5'-AMP...

Clock molecule's sensitivity to lithium sheds light on bipolar disorder

...bipolar disorder. The findings, which also provide insight into clock-controlled aspects of metabolism, are reported in this week's issue of Science. "We're interested in the internal control of metabolism because feeding behavior is on a daily cycle, and hormonal activities that regulate this are circadian...

U of MN researchers identify ataxia gene

'Executive' monkeys influenced by other executives, not subordinates

...pherd, such studies in monkeys will enable greater insight into the basic machinery of social interaction. "Thanks to a combination of molecular and behavioral studies, we're starting to be able to investigate the neural machinery that allows humans to empathize, to form strong social bonds, to do things li...

Study finds drug may cut down involuntary movements

...ease, where patients usually lose their memory and insight into their disease at some point, most Huntington's patients understand exactly what is happening to them throughout most of their illness. The disease usually strikes people in their 30s and 40s, though some patients are affected as early as childh...

Mechanism for memory revealed in neurons of electric fish

...s at Austin studying electric fish have gained new insight into how memory is stored at the level of neurons. Their finding, published in the Feb. 16 issue of Neuron, could help researchers better understand memory formation and neural disorders like epilepsy in humans. Dr. Harold Zakon, Dr. Jörg Oestreic...

Marine mammals are on the frontline of failing ocean health

...ng new every single month, and we continue to gain insight into what is going on with the ecosystems in which marine mammals live. This information will help us tackle how to ensure the future health of the oceans - and ourselves." ...

UF scientists reveal ancient origin of vertebrate skeleton

...ll, the lamprey and its cousin, the hagfish, offer insight into the early Cambrian period 540 million years ago, when multicellular animals first began to make shell and other hard body parts. About 40 million years into the process, jawed and jawless vertebrates branched into different paths from the starti...

Enzyme inhibitors block replication of SARS virus

...g said the findings published today provide better insight into the mode of action of the enzyme, which may lead to development of a drug against SARS. The findings were made by using rapid drug discovery techniques developed in the Wong lab to screen large numbers of weak enzyme inhibitors, and then attachi...

Scientist uses dragonflies to better understand flight

...aight line? Some are -- that's what I found." The insight came from dragonflies. "Dragonflies have a very odd stroke. It's an up-and-down stroke instead of a back-and-forth stroke," she said. "Dragonflies are one of the most maneuverable insects, so if they're doing that they're probably doing it for a rea...
