Gene researchers close in on nicotine's 'evil cousin'

...ns also warrant an interested eye. And if they can verify that the gene is of the type known as a "P450," they'll have narrowed their search to about 500 genes - which is progress in Dewey's line of work. Dewey also has access to the Genome Research Lab's microarray technology, which automates and computer...

MRI technique lets researchers directly compare monkey and human brains

... wrong. Now we have a way to verify when the monkey model does not apply and when it really can apply, Orban said. And we can be much more precise in extrapolating findings from monkeys to humans....

$10 Million center for theoretical biological physics created at UCSD by NSF

...e predictions. And if you can make predictions and verify them, you gain insight into complex biological processes that now appear unpredictable." In addition to generating biological insights, the center will also be a catalyst for the newly emerging field of complex system physics. According to Herbert Le...

Interpreting a climate record from 10,000-year-old migrating waters

...ents. This is one of the things needed to test and verify global climate change models," said Glassley. To interpret such a climate record, however requires conducting highly detailed computer simulations of a large amount of data describing the properties of the rocks on a scale not usually measured. Ther...

New Stanford study casts doubt on developmental potential of adult stem cells

...th recent work from other labs that also failed to verify adult stem cell plasticity, should dim the enthusiasm for pursuing research only in adult stem cells. "I hope it tempers the enthusiasm for adult stem cell plasticity. Maybe it's not the answer that it appeared to be," she said....

Scientists prove how geckos stick, unlock secrets to making artificial gecko glue

...are made of--determine the gecko's stickiness. To verify its experimental and theoretical results, the gecko group then used its new data to fabricate prototype synthetic foot-hair tips from two different materials. "Both artificial setal tips stuck as predicted," notes Autumn, assistant professor of biolo...

Investigators use guilt-by-association strategy to track potential cancer causing genes

...had been known previously. The team next plans to verify whether the genes they have identified are indeed activated in their set of experimentally-induced mouse lymphomas. If so, based on the similarity between the human and mouse genome, they can begin to examine whether human tumors contain hyperactivat...

Just one bite at a time: Researchers find snake with unusual feeding habit

... a crab is captured and eaten, it was important to verify how the crab is actually pulled apart. So, Jayne brought the snake into his laboratory and recorded Gerarda's feeding behavior using an infrared IR) camera. "They're kind of a bashful species," said Jayne. They wouldn't eat when I watched them, but w...

Collaboration advances potential therapy for autoimmune diseases

...cientists have worked closely with the Russians to verify research results, monitor progress and identify and secure a viable commercial partner. PNNL is the technical lead for most biological and chemical-related projects conducted throughout several national laboratories for IPP. "This agreement will al...

Stanford researchers shine light on new genes involved in multiple sclerosis

...o test novel proteins for use in preventing MS. To verify that proteins found in this study could lead to possible cures, Steinman tested two treatments in a mouse model. In one, he created a mouse line that was prone to developing MS but lacked a gene that was overexpressed in chronic MS. These mice had fe...

Fusion in a flash?

...are needed to account for this discrepancy, and to verify the observed relations between the neutron emissions, tritium production, and bubble collapse. If fusion is confirmed in further tests, these bubbles would still have a long way to go before they could be considered as a possible energy source with ...

Satellites tracking climate changes

... paper, cautions that additional work is needed to verify the existence of the climatic trigger for Ebola. "It's fortunate for those affected by Ebola that we have so few outbreaks to study, but it makes our job more difficult," said Tucker. "Drawing conclusions from a small sample is risky."...

Subjects lying face up reveal a reduced ability for 'nasal air conditioning'

.... Flexible nasopharyngoscopy was then performed to verify the position of the probe. The nostril containing the probe was then occluded anteriorly with a wax plug. After that, a second series of baseline measurements was obtained that included blood pressure, pulse, nasal volume, and nasal mucosal temperatu...

UCLA researchers invent first technique to image Alzheimer's onset

...ory centers of nine Alzheimers patients brains. To verify their findings, the researchers performed a brain autopsy after one of the patients died. The post-mortem tissue showed FDDNP-stained lesions in the brains memory centers confirming the results of the patients PET scan. "When Alzheimers disease str...

Bacteria's natural foe fights drug-resistant infections

...al cell wall that will be difficult to change. To verify this theory that resistance will be a rare event, the researchers repeatedly exposed bacteria to increasing concentrations of the enzymes. Not once did resistance organisms develop, the scientists report in Science. Moreover, these enzymes are unlike...

Hopkins researchers develop potential new screening test for prostate cancer

...rly studies, and additional tests are necessary to verify the usefulness of the diagnostic technique. Prostate cancer is the second leading cause of cancer death in men in the United States. Approximately 198,100 men were diagnosed last year and an additional 31,500 men died from the disease. Participants ...

University of Cincinnati researchers track climate changes in Arctic thaw lakes

...ns in order to determine the age of the basins and verify that their classification scheme is correct. The oldest of the basins they examined dates back 5,000 years, while the youngest was 20-30 years old. They're also using satellite imaging to recognize and categorize thaw lake basins, with the help of ge...

New insight into diet and colon cancer

Though more work will be needed to better understand how diet affects the spread of cancer at the cellular level, Carroll says that...

Rutgers-led researchers discover new photosynthetic bacteria that appear to be significant component of ocean's carbon cycle

...ast year, Kolber and his team originally sought to verify the presence of the strange bacteria at hydrothermal vents on the ocean floor in the northeast Pacific. "It was postulated that the light generated by the superheated water in thermal vents and chemical processes taking place around ...
