Seaweed could make junk food healthier

...aminaria, found in the Far East, South America and parts of Norway and Scotland. The seaweed is processed in the laboratory to produce the extract, alginate, a carbohydrate compound which is a tasteless and odourless off-white coloured powder. The paper shows that alginate has been proved to strengthen mu...

Discovery of T-cell 'traffic control' boosts new drug promise

...s and flood on into blood vessels that lead to all parts of the body," Goetzl says. "We asked ourselves, 'What is the brake?'" In research with mice that have T cells that lack S1P receptors or have over-expressed receptors, the Goetzl and Rosen labs and others determined that T cells have on their surfac...

Industrial contaminants spread by seabirds in High Arctic, new Canadian study shows

...emitted into the air and oceans from the populated parts of the globe, and are transported by air and ocean currents toward cold areas like the Arctic. "Some chemicals will build up in the food webs that comprise northern traditional diets," says Ms Kimpe. "As a result, some of our northern Canadian popul...

Microbe has huge role in ocean life, carbon cycle

...comparison, humans are mostly junk DNA, with large parts of the human genome having no important function," Giovannoni said. This type of genome streamlining, researchers say, appears to be a major factor in the evolutionary success of SAR11, which they believe may have been thriving for a billion years o...

... camels and other large wild animals may soon roam parts of North America. "If we only have 10 minutes to...lows. Today, there are 60 percent fewer willows in parts of Colorado where beavers have declined. Similarly, after major predators became extinct in Montana...

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

... Celsius in the summertime. "We know that certain parts of the Arctic are warming pretty substantially and more so than in other regions around the globe," Epstein said. "This is significant because conditions in the Arctic affect global atmosphere conditions. The Arctic is dominated by snow and ice, and ...

Naturally occurring asbestos linked to lung cancer

... In some undeveloped areas of the world, including parts of Greece and Turkey, mesothelioma cases have been linked to use of naturally occurring asbestos in household materials such as whitewash. The UC Davis study suggests naturally occurring asbestos also causes mesothelioma in developed countries, throu...

UIC developing drug for SARS

... the chain to release the individual proteins, the parts needed to assemble a mature virus. These two proteases -- called 3CLpro and PLpro -- are UIC's targets for drug therapy. "If we can block 3CLpro and probably PLpro, then we can stop the SARS virus from replicating," Johnson said. Under the grant, ...

Digging in the dirt for life's biochemical foundations

...n, which remains common in rapidly industrializing parts of the world, such as China. Eventually, an intricate knowledge of the nitrogen cycle might lead to more efficient use of fertilizers, more productive output on low-input and organic farming operations, and improved ability to stanch the effects of ...

Modification of program enables prediction of gene transcription

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...o has begun searching for devil's gardens in other parts of the western Amazon to see how widespread the herbicide phenomenon is. "Megan's work reveals a system that is amazing because the ants exert so much control over their environment, creating single-species stands in one of the most diverse places o...

New understanding of jet lag

Gradient guides nerve growth down spinal cord

...een each pair of vertebrae and extend to different parts of the body, for example the hand or foot. Zou and colleagues studied the guidance system used to assemble this complex network in newborn mice, where corticospinal axon growth is still underway. Before birth, axons grow out from the cell body of a ...

Evolution of life on Earth may hold key to finding life in outer space

...nts of the ribosome machinery trying to learn what parts came first and what was added later. "Since many of the components of the ribosome are shared by all organisms, we know this machinery is very, very old," Fox said. "If we can discover the earliest aspects, then scientists may be able to devise expe...

Variant prion protein causes infection but no symptoms

...t abnormal prion protein accumulations to specific parts of the brain where they will not produce symptoms. "Abnormal prion protein by itself may not be rapidly lethal--in these mice it wasn't," Dr. Chesebro says. ...

Infectious disease expert warns of spread of Rocky Mountain spotted fever

...tern of pink-to-red spots over the entire body, or parts thereof. The rash is also noticeable on the soles of the feet and palms of the hands, where rashes do not usually appear. At this later stage of infection, antibiotic therapy becomes somewhat less effective. In the CDC-led study, government research...

Green diesel: New process makes liquid transportation fuel from plants

...of carbohydrates, a wide range of plants, and more parts of the plant, can be consumed to make fuel. "The current delivered cost of biomass is comparable or even cheaper than petroleum-based feedstock on an energy basis," Huber says. "This is one step in figuring out how to efficiently use our biomass re...

NYU biologists map out early stages of embryo formation

...gans, the researchers sought to comprehend how the parts encoded by the genome are used to build complex dynamical biological systems--in this case, an engineering diagram for embryo formation. Using a new way to combine results from different functional genomic approaches including RNA interference (RNAi)...

Scavenger cells could be key to treating HIV-related dementia

Surgical Robot 'Scrubs In' At UNC, May Be More Precise Than Conventional Surgery

...y to perform the delicate nerve sparing and sewing parts of the procedure," he said. Patients, in turn, recover quickly and are able to resume their normal life within days of major surgery instead of months, Boggess said. "The robot provides the laparoscopic surgeon with a degree of precision and safety...
