Simulations unravel outer membrane transport mechanism

...gging mechanism is very unlikely.” Coupled with increasingly sophisticated crystallographic studies and basic biological data, simulations help researchers study the interactions of multiple proteins in complex systems, such as the TonB-dependent transporter, Gumbart said. “As we get more computational powe...

Salty oceans provide early warning for climate change

...rical models and palaeoclimate data scientists are increasingly realising that salt is the key. Their results reveal that a build up of salty water can stimulate deep water circulation, while a diluting of the waters is linked to sluggish flow. “Salt plays a far more important role that we first thought,” says...

Researchers examine carbon capture and storage to combat global warming

...ton of carbon dioxide it emits, so that it becomes increasingly costly to be dirty. Thus the taxes encourage companies to be green. When a clean technology is expensive-incorporating carbon capture and storage into a power plant costs $30 to $70 per ton of carbon dioxide-taxes on emissions level the playing fi...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

... cell types. But as genetic techniques have become increasingly powerful, many scientists have sought a more molecular definition of stem cells, based on the genes they express. Now, a team of Canadian scientists has identified 1,155 genes under the control of a gene called Oct4 considered to be the master regu...

Want to save polar bears? Follow the ice

...ear. Bears that make it to shore may be there for increasingly longer periods of time without food as the sea ice becomes more distant and inaccessible. The main question for conservationists is which of the existing 18 populations of polar bears occurring on two continents and one sub-continent stand the be...

Lessons from the orangutans: Upright walking may have begun in the trees

...ernately wetter and drier, and the rainforest grew increasingly patchy. Apes living in the forest canopy would have begun to encounter gaps between trees that they could not cross at the canopy level. The Science authors suggest that early human ancestors responded to this by abandoning the high canopy for ...

Only after the team analyzed the fly behavior with methods developed by co-authors George Sugihara and Chih-hao Hsieh from the Scripps Institution of Oceanograph...

MIT model helps researchers 'see' brain development

...coarsest folds. By adding more points, she created increasingly finer-grained domains of smaller, higher-resolution folds. Finally, Yu modeled biological growth using a technique recommended by Grant that allowed her to identify the age at which each type of fold, coarse or fine, developed, and how quickly. ...

OHSU surgeon implants donated tissue allografts

... OHSU surgeons and administrators, Oregonians will increasingly benefit from those in our community who donate their tissue for transplantation. Recently, as a result of these unique efforts, the national leader in fresh allograft cartilage preparation, AlloSource of Centennial, Colo., has partnered with Comm...

NT researchers discover breakthrough in malaria treatment

...ers at risk of disease. Vivax malaria is becoming increasingly resistant to standard treatments, but few studies have determined the best way of treating it. In collaboration with partners at the Indonesian Ministry of Health, the MSHR team conducted a study in Papua, where they compared, head to head, two n...

The summer of 2006 was the second warmest in the continental United States since records began in 1895, according to the National Climatic Data Center. Moderate to extreme drought conditions were evident in about 40 percent of the cou...

Misusing vitamin to foil drug test may be toxic; plus, it doesn't work

... Medicine. "Testing urine for drugs is becoming increasingly common for job applicants," said study leader Manoj K. Mittal, M.D., a fellow in Emergency Medicine at The Children's Hospital of Philadelphia. "Because niacin is known to affect metabolic processes, there is a completely unfounded claim that it can ...

Darwin's famous finches and Venter's marine microbes

...enter’s crew siphoned seawater through a series of increasingly fine filters to collect the microbes, which they sent back to the J. Craig Venter Institute in Maryland. In the lab, the scientists shredded the collected genetic material in millions of random snippets and then determined their sequence. Based o...

"Over the course of the training, the participants got better at finer and finer category discriminations," Riesenhuber said. "This represents a crucial step in category learning where small differences in shape can have a big impac...
