Researchers examine carbon capture and storage to combat global warming

...as never enters the atmosphere. The practice could transform heavy carbon spewers, such as coal power plants, into relatively clean machines with regard to global warming. ''The notion is that the sooner we wean ourselves off fossil fuels, the sooner we'll be able to tackle the climate problem,'' said Sally...

Premature births may be linked to seasonal levels of pesticides and nitrates in surface water

...a momentous observation, which hopefully will help transform the way humanity cares for its world," said James Lemons, M.D., Hugh McK. Landon Professor of Pediatrics at the IU School of Medicine.

Synthetic peptide targets latent papilloma virus infections

...ogens, such as HIV in blood cells. The virus can transform infected cells and make them proliferate into nipple-like warts. Unlike unsightly warts on the skin, tongue or penis, warts in the cervix are often flat and easily overlooked unless laboratory staining is used to find signs of pathology, as in Pap sc...

Molecular differences between early and advanced melanomas could provide new drug targets

...hat Akt overexpression on its own is sufficient to transform radial growth melanoma cells into highly invasive tumors via reactive oxygen pathways," says Dr. Arbiser. "This could provide us with promising targets for anti-cancer drug therapy. We will continue to work on refining the exact mechanisms of how Ak...

Scientists discover new life forms in the Arctic Ocean

...n biliproteins, highly fluorescent substances that transform light into biomass, and phyte meaning they are plants. The discovery came from carefully analyzing DNA sequences belonging to vast communities of micro-organisms living in the ocean. "There was one group of sequences that just didn't line up with ...

Researchers create artificial enzyme that mimics the body's internal engine

...ee centers provide the four electrons necessary to transform oxygen into water. "How all four electrons are added to oxygen has always been mysterious," Collman said. "Very few people study it. It's quite complex, and it's been broadly ignored." Each electron is brought to the enzyme one at a time, Collman ...

Engineering the heart piece by piece

...hese possibilities are all within reach, and could transform the way heart care is delivered, say University of Michigan Medical School researchers in the new issue of the journal Regenerative Medicine. Technology has advanced so much in recent years, they write, that scientists are closer than ever to “bioeng...

New science of metagenomics 'will transform modern microbiology'

...be grown in laboratory culture. Metagenomics will transform modern microbiology by giving scientists the tools to study entire communities of microbes -- the vast majority of which are likely to be previously unknown species that cannot be cultured -- and how they interact to perform such functions as balanci...

Cholera pathogen reveals how bacteria generate energy to live

...thogen, while also offering insight into how cells transform energy from the environment into the forms required to sustain life. As a single-cell organism, Vibrio cholerae depends on resources in its immediate environment to sustain itself. Blanca Barquera, assistant professor of biology at Rensselaer and pr...

Chromosomal microarray analysis proves accurate

More important, the technique found abnormalities in 5.2 percent of patients for whom more traditional techniques had not identified the genetic cause. "We are constantly improving the test," ...

Unique tomatoes tops in disease-fighting antioxidants

...lycopene. "We don't know why our bodies seem to transform lycopene into cis-isomers, or if some isomers are more beneficial than others," Schwartz said. The researchers don't know if tomatoes rich in cis-lycopene would provide greater health benefits to humans, but the study's results suggest that tomato...

Receptors are molecules on the surface of cells that permit the virus to dock with the cell and commandeer it to initiate a cascade of infection. By knowing wha...

Newly discovered behavior in cancer cells signals dangerous metastasis

...w, scientists have believed that cancer cells must transform permanently from stationary epithelial cells into migratory mesenchymal cells in order to metastasize. The Duke team discovered that highly malignant cells are equal parts epithelial and mesenchymal, transitioning between the two as their surroundin...

Malaria vaccine prompts victims' immune system to eliminate parasite from mosquitoes

...l form. Some of the Plasmodium cells, however, transform into gametocytes—the sexual forms of the parasite that are equivalent to sperm and eggs. Fertilization takes place in the mosquito gut, after which the parasite imbeds itself in the gut lining. There, it passes through discrete stages, before migra...

New biochip helps study living cells, may speed drug development
