NIDA study identifies genes that might help some people abstain from smoking

...ngs provide ample justification for continuing the search for even more genetic variants associated with smoking cessation success,?says Dr. Volkow. “We soon may be able to make use of this information to match treatments with the smokers most likely to benefit from them.? ...

It's never too late to get it back! Aging interrupted

... and his colleagues used their screening method to search for drugs which cause pre-cancerous and cancerous cells to commit suicide and to replace those cells with new, healthy cells. It is thought that the body does this because it normally kills some cells like damaged and rogue cancer cells to provide e...

Genome sequencing reveals key to viable ethanol production

...ular biomass. He’s also continuing the genome-wide search for enzyme combinations that will degrade and ferment grasses, corn stovers, and even food waste. "I don’t think this is the revolution that makes ethanol a mainstay," says Wu, "but I believe this is a part of what will lead to the revolution." Thi...

Flies don't buzz about aimlessly!

...earching is intermittent, such that flies actively search by making tight turns, and fly straight some distance to begin searching again. Scale-free movement patterns have been found in diverse animals including zooplankton, wandering albatrosses, jackals, and even human hunter-gathers. Intermittent searche...

Stanford-led study closes in on genes that may predispose some people to severe depression

...e said. "Understanding the biology would help the search for better treatments." The next phase of the consortium's research is already under way. This phase is an even more detailed look at more than 2,000 individuals to identify specific genes where there are variations that increase the risk of s...

Researchers identify gene involved in dog size

...compare the human and dog genomes and narrow their search for genetic contributors to cancer and other major diseases. Researchers can access the dog sequence data through the following public databases: Dog Genome Resources ( http://www.ncbi.nlm.nih.gov/genome/guide/dog ) at NIH's National Center for Bi...

LIAI completes world's most comprehensive analysis on influenza virus data

...irus, or 100 different times. Now, scientists can search the database and find out all existing information on their particular topic. This will enable them to avoid unnecessary repetition and make faster progress toward new therapies and vaccines." The database, publicly accessible at http://immuneEPI...

Tracking sperm whales and jumbo squid

... sea level]," the authors wrote. "How sperm whales search for, detect and capture their prey remains uncertain." To find out, the researchers traveled to the Gulf of California, also called the Sea of Cortez—a narrow stretch of ocean that separates the Mexican mainland from the Baja Peninsula. "The ce...

Mimicking how the brain recognizes street scenes

...omobile driver's assistance, and eventually visual search engines, biomedical imaging analysis, robots with realistic vision. On the neuroscience end, this research is essential for designing augmented sensory prostheses, such as one that could replicate the computations carried by damaged nerves from the r...

Bacterial walls come tumbling down

...building enzyme from S. aureus will accelerate the search for an effective weapon against the infamous superbug. The images produced by Strynadka's team show the enzyme frozen in place by a powerful antibiotic called moenomycin. Moenomycin has been used for decades in animal feed to promote livestock gro...

NASA predicts nongreen plants on other planets

..."This approach -- studying Earth life to guide our search for life on other worlds -- is the essence of astrobiology." Kiang and her colleagues calculated what the stellar light would look like at the surface of Earth-like planets whose atmospheric chemistry is consistent with the different types of star...

Trusting your instincts leads you to the right answer

... controlled the time allotted to each individual's search for their target. The visual display screen was switched off at various time intervals either before or after the subjects' eyes landed on the target. When the on-screen image was hidden immediately after the subjects' eyes had landed on the target, ...

Are we killing the world's oceans?

...researchers and government decision-makers as they search for answers at a forum hosted by the University of Victoria on Feb. 21-22. The gathering, which is open to the public, will address scientific and policy issues of critical importance to the future of Earth's oceans. The event is part of a series ...

Autism gene identified by researchers at Yale working with a global research consortium

...lmost 1,200 families. They also scanned the DNA to search for copy number variations, which are submicroscopic insertions and deletions of genetic material that scientists believe may be linked to autism and other diseases. The researchers found neurexin 1, part of a family of genes that plays a role with t...

Darwin's famous finches and Venter's marine microbes

...u start with all of them together, which makes the search much more sensitive, but also very computationally expensive," Manning says. "We did almost 350 million comparisons, which is probably an order of magnitude or two more than anybody has ever done before." Manning and co-author Yufeng Zhai, Ph.D., ...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

... for a particular recipient, Mousses said. To search for target genes that regulate Tykerb response, Mousses and his colleagues performed a genome-scale scan of two cancer cell lines using high-throughput RNAi, "interfering" RNA strands that bind to and knock out one gene individually, across the genom...

Lost dogs found more often than lost cats, study suggests

...r pet, including what kind of methods they used to search for the missing animal. The researchers also asked the owners if the animal was wearing an identification tag; a rabies tag; a dog license tag (applies only to dogs); or had a microchip at the time it disappeared. Each shelter scanned animals for m...

Scientists find new genetic clue to cause of Alzheimer's disease

Computer scientists join in search for ivory-billed woodpecker

...roblem." Song and Goldberg took interest in the search for the ivory-billed woodpecker after Goldberg read an article about the search in The New York Times. Goldberg contacted the co-leaders of the search from Cornell's Laboratory ...

Cancer researchers add spice to research against rare neuromuscular disease

... issue of the journal Nature Medicine. In their search for new treatments for prostate cancer and other diseases, Chawnshang Chang, Ph.D., and his colleagues have taken a few cues from centuries of Asian tradition, where curcumin ?the bright yellow spice found in curry powder ?has been used to treat a va...
