UF study first to quantify validity of DNA I.D. tool using marine snails

...ful identification tool for ecologists who may not necessarily be taxonomy experts, he said. "This new technology is seen as kind of a fancy, cool tool that will revitalize museums, which will house the reference collections, and generate 'gee whiz' appreciation from the general public as well," he said. Much ...

Restoring silenced suppressor gene kills lung-cancer cells

...We don't believe that using WWOX as a therapy will necessarily eradicate tumors, Fabbri says, "but we do believe that this kind of gene therapy might be useful when used in combination with chemotherapy and other therapies." ...

New view of cancer: 'Epigenetic' changes come before mutations

...ary tumor, Feinberg notes. These properties do not necessarily require other mutations to occur. "Greater attention should be paid to the apparently normal cells of patients with cancer or those at risk for cancer, as they might be crucial targets for epigenetic alteration and might be an important target for...

Womb needed for proper brain development

...contrast, once the premature infant is born, he is necessarily bombarded by a complex environment full of sights, sounds, touches and unnatural loss of movement. "This research suggests that stimulation of the brain while it is still under construction may not be beneficial," said Dr. Witelson. "The prefrontal ...

Phenotype is influenced by nature, nurture and noise

...also, in a larger sense, why identical twins don't necessarily have identical fingerprints," said Hasty. "Given that every potential feature of an organism is ultimately determined at the genetic level, it is important to zoon in on the noisy details of gene expression to explain the variability that we couldn't...

Discovering the first steps in transcription-coupled repair

...ing that a hitch in the transcription process, not necessarily involving damage to the DNA itself, is the cause of subsequent problems. "It appears that XPG is needed to help CSB recognize the stalled RNAPII and carry out its other functions in TCR," says Cooper. "We think that even if CSB is present, if the ce...

Tuberculosis still a risk for patients receiving HIV drugs

...tive Lazzaro Spallanzani in Rome. But they don't necessarily have to leave the country to contract TB. HIV-infected American and European patients who are "exposed to someone with tuberculosis, for example in a hospital setting, are at increased risk of acquiring tuberculosis infection and of developing active...

ASU researchers 'wire' DNA to identify mutations

...y 1,000 DNA bases, though not every SNP found will necessarily cause a disease mutation. Cataloging these subtle DNA differences among the populace will aid the ongoing quest to understand and prevent disease. "There is a high demand to track mutations for cancer research or future applications in personalized...

Study ties 'new' cell-death mechanism to developmental and degenerative brain disorders

... said the new findings on neurodegeneration do not necessarily supersede the prevailing hypothesis of defective proteins. In fact, the two may be linked. "It could be that the behavior of the nerve cell is altered, making it more susceptible to the onslaught of misfolded proteins, and it could be that misfolded...

Pitt professor's theory of evolution gets boost from cell research

...d because they don't exist, since evolution is not necessarily gradual but often sudden, dramatic expressions of change that began on the cellular level because of radical environmental stressors--like extreme heat, cold, or crowding--years earlier. Determining the mechanism that causes those delayed expression...

Learning to love bacteria: Stanford scientist highlights bugs' benefits

...d. "All these observations have been made without necessarily trying to pull it all together," said Falkow. "So what I tried to do in this article is to point out that the continued presence of these organisms in human society may actually be beneficial to the host and that is why they are tolerated by the immu...

Scientists look to the Bahamas as a model for coral reef conservation

Birds that make teeth

Gone does not necessarily mean forgotten, especially in biology. A recent finding by researchers at the University of Wisconsin, Madison, and colleagues from the University of Manchester have found new evidence that the ability to form previously lost organs--in this case, te...

World faces challenge as life expectancies lengthen, scientist says

...ny countries, this would have an enormous, and not necessarily positive, impact. For example, the idea that China would go from 1.5 to 1.8 billion, just because of this, is a bit frightening." On the other hand, he said, a longer-lived population could be good news for many European countries with low fertility...

Cancer cells suppress large regions of DNA by a reversible process that can be tackled

...enes were silenced by methylation. But this is not necessarily the case. "What we've found is that non-methylated genes that reside in a particular suburb near methylated genes are also silenced. Their physical proximity to the methylated genes affects their ability to function. It's a case of being in the wrong...

Stanford study of owls finds link in brain between sight and sound

...e ability to hear and the direction of gaze aren't necessarily linked," said the paper's first author, postdoctoral scholar Daniel Winkowski, PhD. Sounds originating from any direction don't require visualization to be heard. "It's exciting to find that the circuits in the brain that control gaze direction affec...

Salmonella caught red-handed

...w enzymes in certain metabolic pathways are really necessarily to keep Salmonella bacteria alive. Most of these essential enzymes are missing in other important pathogens, or they are also present in the human organism, so they cannot be considered possible points of attack for new broad-spectrum antibiotics wit...

Insects and mammals share common fat-building pathway, study suggests

...duce weight gain and its consequences ?this is not necessarily so." Extra calories have to go somewhere, he said. If fat formation is blocked, lipid deposits may instead build in other parts of the body, such as muscle or liver. "The 'problem' in obesity is energy balance that is out of whack, and not a surfeit ...

Variation in bitter-taste receptor gene increases risk for alcoholism

...ation is more common in African Americans does not necessarily mean African Americans will have a higher incidence of alcoholism. The difference in the TAS2R16 gene is only one of several genetic and environmental factors involved in risk for alcoholism, according to Goate. "I don't think our result has any imp...

MIT research holds promise for Huntington's treatment

...dence suggests that the largest inclusions may not necessarily be harmful and could in fact be protective, said Bodner. So, the MIT and Harvard scientists decided to look for compounds that actually promote the formation of large inclusions. The highest concentration of protein inclusions was found when the res...
