Army research mission focused on autism

...o shape the focus of the ASDRP. "This is a very unique opportunity to allow the scientists and advocates to focus on a common cause, improving the lives of children with autism, to produce research that will lead to making a real difference," said Peter Bell, executive vice president of Autism Speaks, wh...

E. coli bacteria migrating between humans, chimps in Ugandan park

...es from 25 humans and 23 chimpanzees. Of these, 89 unique genotypes (strains) of E. coli were found. The E. coli strains from the chimps were more like those of the humans working in the park than like humans living in the village. "This expands our notion of the situations in which people and chimp...

'Terror bird' arrived in North America before land bridge, study finds

...th elements' concentrations change, resulting in a unique chemical signature. "We used rare earth elements because they're highly specific to certain time periods and different groundwater conditions," MacFadden said. "This is the first time that the uptake of rare earth elements during the early stage o...

A revolution in the monitoring of unborn babies

...e both heart rates as well as fetal position. This unique home monitoring device could lead to a new approach in the management of pregnancy. Dr Margaret Ramsay says it will play a key role in monitoring high-risk pregnancies. “For all these fetuses, the more we can monitor them, the greater the chance ...

New dopamine brain target discovered

...Dowd and their team identified this complex by its unique reaction to dopamine or specific drug triggers. Strikingly, stimulating this target with dopamine or specific drugs triggered a rise in calcium in the brain. As calcium has a profound effect on almost all brain function, this rise in calcium causes ...

Fish can determine their social rank by observation alone, study finds

...n. 25 edition of the journal Nature, is based on a unique experiment with cichlids (SIK-lids), small territorial fish from Africa. "In their natural habitat, male cichlids are constantly trying to ascend socially by beating each other up," said study co-author Russell D. Fernald, professor of biological sci...

Plants do not emit methane

Satellites shed light on global warming

...uces data of unrivalled accuracy on account of its unique dual view of the Earth’s surface, whereby each part of the surface is viewed twice, through two different atmospheric paths," Llewellyn-Jones added. "This not only enables scientists to correct for the effects of dust and haze, which degrade measurem...

Fruit fly gene research may shed light on human disease processes

...cell activities. "This signaling process is not unique to embryonic sex differentiation, but occurs in hundreds of genes throughout the body, in flies and in higher animals, too," Avila says. "Our work sheds light on signal transmission in humans." Erickson points out that flies have evolved along wi...

How fish conquered the ocean

...taceous and early Paleogene Periods. The work is a unique hypothesis that integrates the cellular and molecular physiology of teleost reproduction with their evolutionary and environmental history. "The oceans have not always been filled with fishes as nowadays" says researcher Dr. Roderick Nigel Finn at t...

Stem cell therapy shows promise in regenerating damaged muscle in heart attack patients

...t tissue type matching to a specific patient. A unique benefit of the stem cell product is that it is given to patients through a standard IV line. Other therapies require delivery to the site of the disease through catheterization or open surgical procedures, but this one was very simple and easy for th...

Ring-around-the-cell

...usiness. The cells, called osteoclasts, have some unique features not seen in any other cell type. Osteoclasts move around the bone until they reach a site where they sense that their services are required, at which point they undergo a transformation called polarization. The polarized osteoclast sticks it...

Colour sensor breath test can detect lung cancer

...l colour sensor, which detects tiny changes in the unique chemical signature of the breath of people with lung cancer. Metabolic changes in lung cancer cells cause changes in the production and processing of volatile organic compounds, which are then breathed out The researchers used the colour sensor...

Reversing cancer cells to normal cells

...sed an innovative experimental approach to provide unique insights into how scientists can change human metastatic melanoma cells back to normal-like skin cells - by exposing the tumor cells to the embryonic microenvironment of human embryonic stem cells, the zebra fish and the chick embryo.

Major link in brain-obesity puzzle found

... altered genetically so that they only expressed a unique form of the SH2B1 protein in their brain cells. The protein occurs elsewhere in the body, but the researchers were able to zero in on its activity in the hypothalamus: the area of the brain that coordinates signals from the brain and body relating to...

New UD technology removes viruses from drinking water

...ater Act, which took effect on Jan. 8. "What is unique about our technology is its ability to remove viruses--the smallest of the pathogens--from water supplies," Pei Chiu, an associate professor in UD's Department of Civil and Environmental Engineering, said. Chiu collaborated with Yan Jin, a profess...

NYU scientists identify how development of different species uses same genes with distinct features

... repress posterior development. However, bicoid is unique to flies and does not exist in wasps or other species: The study’s findings show that it takes several mRNAs localized in the egg to achieve the same functions in wasps as bicoid does in flies. Two of these genes, which are found in most species of i...
