Envisat captures first image of Sargassum from space

...ospheric carbon dioxide through photosynthesis and convert it into organic carbon. By absorbing half of the carbon dioxide emitted into the atmosphere, the oceans have a profound influence on climate, making them major areas of interest for climate modellers. The discovery was made using the MERIS maxim...

Pesticides choke pathway for nature to produce nitrogen for crops

...e friendly bacteria, which work with the plants to convert atmospheric nitrogen into ammonia that, then, is used as fertilizer by the plants. "Agrichemicals are blocking the host plant's phytochemical recruitment signal," said the study's lead author, Jennifer E. Fox, a postdoctoral researcher in the Cent...

Modified mushrooms may yield human drugs

...ith mushrooms, we can use commercial technology to convert the vegetative tissue from mushroom strains stored in the freezer into vegetative seed. A crop from which drugs may be extracted could be ready in weeks," Dr. Romaine said. A mushroom-based biofactory also would not require expensive infrastructure s...

The sound of proteins

...rank Pettit, which uses their translation rules to convert amino acids into music and hope it will speed up the translation of large segments of genomes. Further examples of converted proteins and the computer program are accessible for online use [ www.mimg.ucla.edu/faculty/miller_jh/gene2music/home.html ]....

From the deep -- Researchers find new species of sea anemone

... uses that sulfur to make energy, much like plants convert light into energy." Daly doesn't know much about A. pearseae beyond its physical description. She and Gusmão aren't sure how old the creatures are, and say that sea anemones can live for hundreds of years. Nor are they sure how A. pearseae reprodu...

Decoding protein structures helps illuminate cause of diabetes

...ctions to identify multiple phases as the proteins convert from an unordered mishmash into flat sheets, then coil into fibers. "No matter how fast they're moving, we can take pictures of them," says Zanni. Without their automated method, he says, such experiments would be nearly impossible. The techn...

Fat overrides effects of vitamin C

...te spontaneously forms nitrosating species able to convert a range of targets, such as secondary amines and bile acids, into carcinogenic N-nitrosocompounds. Antioxidants such as ascorbic acid protect against the formation of these nitrosocompounds by converting the nitrosating species back into nitric oxide...

New success in engineering plant oils

...ion of a single enzyme's activity is sufficient to convert the seed oil composition of Arabidopsis from that of a typical temperate pant to that of a tropical palm-like oil," Shanklin said. "It is fascinating ?and potentially very useful ?to know that we can change the oil composition so drastically by simpl...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

...croorganisms or enzymes that will more efficiently convert cellulose into glucose, and finally into ethanol. McBride's interest in C. hutchinsonii goes beyond its possible value in bioenergy. What really intrigues him is that it's a "gliding bacterium," able to crawl rapidly over surfaces by an unknown m...

Scripps research study reveals structural dynamics of single prion molecules

...rt the amyloid conversion process, it has to first convert to an intermediate species, consisting of multiple protein molecules. This insight may be important to finding potential new therapeutic targets for disease-causing amyloids." To define the dynamic structural details of individual prions, Deniz an...

New biofuels process promises to meet all US transportation needs

... to fuel. When conventional methods are used to convert biomass or coal to liquid fuels, 60 percent to 70 percent of the carbon atoms in the starting materials are lost in the process as carbon dioxide, a greenhouse gas, whereas no carbon atoms would be lost using H2CAR, Agrawal said. "This waste is du...

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

...dy of fuel cells-very efficient power sources that convert chemical energy to electricity. "If we can develop better catalysts to do that reduction, we can get better fuel cells," Devaraj explained. ...

Stem cell transplants explored at Stanford as a possible treatment for hearing loss

... hair cells in the cochlea. It's these cells that convert the mechanical energy of sound into electrical impulses that are sent to the brain so that a chicken, a mouse or a human can hear. Chickens, like all birds, have the ability to spontaneously regenerate these hair cells, which explains why there a...

Conceptualizing a cyborg

... brain. For example, the patient's thoughts could convert nerve signals into movements of a prosthetic, while sensory stimuli, such as temperature or pressure provides feedback to adapt the movements. The central feature of the proposed interface is the ability to create transplantable living nervous t...

Bacteria could steady buildings against earthquakes

...esearchers at UC Davis. The microbes can literally convert loose, sandy soil into rock. When a major earthquake strikes, deep, sandy soils can turn to liquid, with disastrous consequences for buildings sitting on them. Currently, civil engineers can inject chemicals into the soil to bind loose grains togeth...

Moonlighting enzyme linked to neurodegenerative disease

A new Mayo Clinic study published in the April issue of the Proceedings of the National Academy of Sciences (PNAS) shows that mutations in a moonlighting enzyme, dihydrolipoamide dehydrogenase (DLD), are responsible f...

Cancer scientists create 'human' leukemia process to map how disease begins, progresses

... Cancer Institute (OCI) have developed a method to convert normal human blood cells into "human" leukemia stem cells. The converted cells, when transplanted into special mice that permit the growth of human cells, can replicate the entire disease process from the very moment it begins. The findings are publ...

Science researchers genetically transform immune cells into tumor fighters

... "We can take normal lymphocytes from patients and convert them to tumor-reactive cells," Rosenberg says, adding that the engineered cells could be tailored to fight tumors other than melanoma. "We've identified T cell receptors that will now recognize common cancers," he notes. The newly engineered T cell...
