Information system to help scientists analyze mechanisms of social behavior

...lop the first complete environment to conceptually navigate all the knowledge about a major model organism," Schatz said. "The BeeSpace environment will include all information relevant to social behavior of honey bees, from genome databases and scientific literature," he said. "This information will be inde...

Breaking new ground in germ cell guidance

...re carried within by a process of invagination and navigate unerringly through the body to contribute to the formation of the gonad, acquiring the characteristics of more mature germ cells en route. The puzzle of how these cells find their way through the developing body has challenged biologists for years, b...

Long-term effects of carbon monoxide poisoning are an autoimmune reaction

...sus CO-poisoned rats, comparing their abilities to navigate and memorize a maze. "CO poisoned rats don't learn," said Thom. "But if you render their immune systems tolerant to altered MBP, by feeding them normal MBP before CO poisoning and thereby short-circuiting the lymphocyte response, the rats learn nor...

Essential smell gene may provide key to new insect repellents

Insects navigate by smell to find food, mates and -- in the case of disease-spreading mosquitoes -- humans to bite. Researchers at Rockefeller University report in the September 2 issue of Neuron that insects' ability to detect odors depends on a single gene. Fruit f...

Prions act as stepping stones in evolution

...s can have a positive side in yeast, helping cells navigate the dicey current of natural selection by expressing a variety of hidden genetic traits. What's more, at the center of this process is a prion, a protein that changes shape in a self-perpetuating way--much like the prion in mammals that is responsi...

Researchers discover how worms' noses sense oxygen

...rkeley - Organisms ranging from bacteria to humans navigate environments that can contain dangerously too little or too much oxygen. Yet, scientists know little about how animals sense oxygen levels around them. Researchers from the Berkeley and San Francisco campuses of the University of California have now ...

Biologists uncover genetic links to broad range of human disorders resulting from cilia dysfunctions

... collection of candidate genes." In humans, sperm navigate toward the egg by propelling themselves with a type of cilia known as flagella. Defects in these whip-like cilia, result in non-motile sperm and male infertility, and are probably the most commonly known type of cilia dysfunctions. Other widely know...

Protein-centric drug development and functional glycomics enrich biopharmaceuticals pipeline

... successful nano-carriers that are small enough to navigate within the body. Thereby, they could serve as effective carriers of active ingredients for cancer treatment. However, dealing with the toxicity of trace nanoparticles that could be left behind in the body, is a major concern. Another promis...

Human genetic sampling

At the end, female pups whose mothers had been exposed to MeHg were slightly impaired on the rope-climbing test, while their male counterparts actually had less hind-limb slips on the...

World's first databank for all living systems

"The ties between biology and the information sciences have always been deep; this project will generate many hard questions for computing and information science, and provide opportunities to apply ...

New research technique provides clues into cell growth

...a, thin filaments that protrude from cells to help navigate through the body. As expected, N-WASP activity was high in these compartments. However, several of the team's other observations surprised them. First, N-WASP and its stimulator proteins CDC42 and PIP2 all were active in "ruffles," animated ridges on...

UT Southwesterns capital campaign passes $300 million mark

UT Southwestern's Clinical Services Initiative is aimed at changing that by putting the patient's perspective at the forefront. We believe this initiativ...

Software tackles protein pathways

...omputer engineers, in turn, have helped scientists navigate these oceans of data through tools such as BLAST, the primary software platform that scientists use to compare protein and DNA sequences. However, many researchers believe that the next phase of genomics research will be to map out interaction networ...

Weizmann Institute scienists find that stem cells in the bone marrow become liver cells

...ls migrate from the bone marrow into the blood and navigate their way to the liver. The findings could lead to new insights into organ repair and transplants, especially liver-related ones. They may also uncover a whole new stock of stem cells that can under certain conditions become liver cells. Until a few ...

Drug improves the sense of touch, Science study says

..."body map." Using these maps unconsciously, humans navigate through the physical world. "We are now finding ways to interact with the brain's body maps. This has enormous power," said Dinse who explained that manipulating body maps housed in the brain can have an immediate impact on behavior and perception. ...

Body clocks keep migrating monarchs on course, Science study shows

...tterflies depend on an internal clock to help them navigate in relation to the sun, scientists have found. By studying monarchs inside a specially designed flight simulator, the researchers have gathered what they believe is the first direct evidence of the essential role of the circadian clock in celestial n...

Early-life environments shape development of stress behaviors and learning abilities in mice

"We completely reshaped the presumed genetic differences between the in-bred mouse strains by changing the pre- and post-natal environmental conditions," said Francis. "The maternal care received by the mice, in addition to the uterine environ...

New study in rats matches genetic influences and cognitive impairment

...rats were trained on two memory tasks, learning to navigate a water maze and remembering familiar objects in their cages. After training, the scientists examined the brain tissue of the rats, specifically the hippocampus, an area associated with memory and cognition. RNA (ribonucleic acid, which carries out...
