Marine 'dead zone' off Oregon is spreading

...f fish, crabs, and other marine life. "There is a huge pool of low-oxygen water off the central Oregon co...nd and current conditions ?can change. This allows huge masses of plant growth to die, decay and in the process consume even more of the available oxygen ne...

Matrilin-3 gene discovered to prevent onset of osteoarthritis

... been associated with osteoarthritis, so this is a huge deal. Now that matrilin-3 has been clearly shown to develop osteoarthritis in an animal model, we can study it further," Chen says. There are four matrilins, or proteins, that form the extracellular matrix (ECM), which holds cartilage together. Mat...

Protein clue to tailor-made antibiotics

Scientists at the University of York have made a huge leap forward in the search for 'smarter' antibiotics. A research group in the Department of Biology has made a significant advance in understanding how bacteria use proteins to conduct a type of biological warfare. Bacteria like E. coli frequent...

How satellite tracking revealed the migratory mysteries of endangered Atlantic loggerhead turtles

... turtles in West Africa and the results could have huge implications for strategies to protect them. In a paper in the journal Current Biology, Dr Brendan Godley and an international team describe how they used satellite tracking systems to follow the journeys of ten turtles from Cape Verde, West Africa,...

Tropical forest CO2 emissions tied to nutrient increases

...Earth by global wind patterns, sometimes riding on huge transcontinental dust clouds, said Townsend, who also is associated with CU-Boulder's ecology and evolutionary biology department. "There is strong evidence that humans are increasing the size of these dust clouds as both land-use patterns and clima...

Heal thyself: Systems biology model reveals how cells avoid becoming cancerous

...ne or genes. The discovery by Ideker's group of a huge network of transcription factor-gene interactions was made possible by new biotechnology tools that provide comprehensive analysis of cells, like a passerby suddenly being able to monitor all the telephone calls made within a city. The team discover...

Basic work on E. coli identifies two new keys to regulation of bacterial gene expression

...lar machines that make proteins and are present in huge numbers in all cells. Since so much of the cell's energy is used to make ribosomes, control of ribosomal RNA transcription is particularly crucial to a cell's well-being. "This work is basic to the growth of all bacteria," says Gourse. "By understa...

WWF captures first-ever photo of wild rhino on Borneo

...nd the forests of the "Heart of Borneo" still hold huge tracts of continuous natural forests, which are some of the most biologically diverse habitats on Earth, with high numbers of unique animal and plant species. It is one of only two places in the world –Indonesia's Sumatra island is the other ?where o...

Researchers appeal for new regulations to save coral reefs from live fish trade

...have devastating effects. Being able to choose a huge fish to eat from a tank is a big pull in luxury seafood restaurants. Fish such as the Napoleon wrasse, a giant reef fish that commonly reaches 2 m in length and lives for more than 30 years, are top of the menu and especially vulnerable. But once o...

Methane-belching bugs inspire a new theory of the origin of life on Earth

...rms. One difficulty with this theory is due to the huge variety and complexity of organic molecules that would have had to arise spontaneously. In contrast, the chemoautotrophic theory rests on the idea that primitive life forms themselves, perhaps associated with catalytic iron and sulfur minerals, gave ...

A single sugar found responsible for an antibody's ability to treat inflammation

...her. This discovery, Ravetch says, has potentially huge implications, and his lab is now working to generate a recombinant form of IgG that, by virtue of a sialic acid molecule attached in the right place, will be anti-inflammatory and could act as a novel treatment for autoimmune disorders. "We have the ...

Research offers new hope for preterm babies

...edside. "Our new near-infrared spectroscopy is a huge advantage for our research. As blood pressure is a constantly-changing, dynamic process, it is vital for us to be able to monitor the changes in brain oxygen levels continuously. With the machine we were using up until now, there was a high risk we w...

Diabetes research takes wing thanks to long-lived fruit fly

...ic of obesity and diabetes," said Bohmann. "It's a huge health issue. Many people have this problem ?it's not going away anytime soon. "This research isn't so much about making people to live to 120 as it is about preventing diseases like diabetes, heart disease, or Alzheimer's. We're trying to identify ...

Study defines effective microbicide design for HIV/AIDS prevention

...mselves, rather than their delivery. "There is a huge push to produce microbicides that would have any effectiveness at all in reducing the spread of HIV, particularly in places like Africa and Southeast Asia where the disease is rampant," said David Katz, a professor of biomedical engineering at Duke's...

Worm links cancer risk to ageing

...s have long known that, statistically, ageing is a huge factor for cancer but have so far struggled to understand why that is. Professor Lithgow said: "If we look at checkpoint proteins as a gear, we have known for a long time that they drive the cancer engine; now we know that they also drive the longev...

Master planners in brain may coordinate other areas' roles in cognitive tasks

...n't find what they expected," he says. "But it's a huge dataset, and the results were very clear." For example, one brain area thought likely to be active in creating task sets, the dorsolateral prefrontal cortex, did not become active as consistently as the cingulate and the opercula. "We're not imply...
