Study finds antibiotic resistance in poultry even when antibiotics were not used

... help. "They banned Baytril in 2005, and if you look at Baytril resistance in campylobacter now it's essentially unchanged," Lee said. In previous studies, Lee has tried to recreate experimentally conditions that should lead to the swapping of resistance genes among bacteria. Lee said these events ...

Scientists find genes involved in the battle between Hessian flies and wheat

...rying to open doors because they are programmed to look for a feeding site. "In resistant plants, the doors are all locked. Then the larvae finally crawl down to the base of the plant and die. This is death by frustration." Hessian flies can be controlled by using specifically bred wheat varieties c...

Mutation improves memory, may lead to memory-enhancing pill

...rks.? "The next step, which is inevitable, is to look for small molecules that mimic this memory-enhancing effect," he continued. "If such a pill could be generated, it might provide a new method for treating people with memory-related diseases such as Alzheimer's," said Mauro Costa-Mattioli, a senio...

New report: Explosive growth changes salmon industry

A new report, the first to take a comprehensive look at market competition between wild and farmed salmon, sheds new light on the contentious and complex issues surrounding farmed and wild salmon. The Great Salmon Run: Competition Between Wild and Farmed Salmon, released by TRAFFIC, the wildlife trad...

Selectivity is ultimate aphrodisiac

... study allowed the investigators to take a serious look at the chemistry that has been at the center of so much literature, art and imagination throughout the ages. "Potential partners who seem undiscriminating are a definite turnoff, and those who evoke the magic of feeling special are a big draw,"...

Researchers identify ovarian cancer biomarkers

...ing," Buckanovich says. Continued research will look at developing antibodies and methods to detect these novel proteins. "In some cases, these are genes that many people have never worked on before," Buckanovich says. ...

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

...o highlights those critical areas where we need to look further. The fact that we don't have a comprehensive vaccine for flu shows we have more work to do. This study shows us where we need to focus going forward." For the influenza study, LIAI researchers analyzed information from 58 different influenz...

Farmed salmon could become an invasive species in forest streams

...een very vocal in stating their views. I wanted to look at the hard evidence to determine the short- and long-term risks to native species in streams on National Forests." Bisson, a staff scientist with the Pacific Northwest Research Station/Forest Service, began work on the report, Assessment of the R...

Bacterial walls come tumbling down

.... Strynadka's team has provided a long-awaited look at the portion of the enzyme used in the first step of the biochemical pathway that initiates assembly of the sugar coating. The second step is targeted by penicillin and has been well studied. Although scientists have spent many years identifying...

Gene variations contribute to aggression and anger in women

... genetically determined. The study is the first to look at the relationship between variations in the serotonin receptor 2C gene and anger and hostility. Completed at the University of Pittsburgh's Behavioral Physiology Laboratory, the study looked at 550 unrelated women of European descent. In order t...

Lithium builds gray matter in bipolar brains, UCLA study shows

... This is the first time researchers were able to look at specific regions of the brain that may be affected by lithium treatment in living human subjects, said Bearden. "We used a novel method for brain imaging analysis that is exquisitely sensitive to subtle differences in brain structure," she sai...

UTSA researchers examine effects of global warming on Antarctic

...g with regional decreases," said Ackley. "If you look at the totality of it, it appears as if it hasn't changed very much over the last 30 years, but it has. Even though we're only seeing these regional changes and not a systemic decline in the amount of ice cover, it is still significant in terms of t...

Researchers find gene mutation that causes infertility in male mice

... been discovered, the researchers say they can now look for similar mutations in the DNA of infertile men. "If you consider infertility a disease, you can't study it like you would other diseases, because the affected people can't reproduce," said John Schimenti, director of Cornell's Center for Vertebra...

NASA predicts nongreen plants on other planets

... Earth, and determined that if astronomers were to look at the light given off by planets circling distant...colleagues calculated what the stellar light would look like at the surface of Earth-like planets whose atmospheric chemistry is consistent with the differe...

Radiation therapy combo cures prostate cancer long-term

... the Seattle Prostate Institute. Doctors wanted to look at the combination of seed implants and external beam radiation therapy, two different types of radiation therapy, to prolong the long-term disease cure rates for prostate cancer. Over the course of 15 years, doctors followed 232 men with early-stage...

Genetic pathways to curable and incurable forms of pancreatic cancer identified

...o different routes to ductal pancreatic cancer can look very much the same under the microscope, involve the same constellation of genetic events, and culminate in invasive and metastatic disease that can ultimately kill patients, one route is 100 percent fatal while the other is 50 percent curable," Hing...

Wired for sound: How the brain senses visual illusions

...ience," she said. Next, the researchers plan to look at whether or not attention affects these illusory sensations. These studies could shed light on how people deprived of one sensation often compensate by developing another ?for instance, blind people with a more acute sense of hearing. ...

Trusting your instincts leads you to the right answer

...ake more accurate decisions when given the time to look properly. Instead they performed better when given almost no time to think. The conscious or top-level function of the brain, when active, vetoes our initial subconscious decision ?even when it is correct ?leaving us unaware or distrustful of our ins...

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

... The consortium used "gene chip" technology to look for genetic similarities in autistic individuals culled from almost 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 l...

University of Alberta researchers unravel intricate animal patterns
