Modeling the restless brain

...esting state fluctuations come from. It also would let them tie neural activity to cognitive and behavioral performance and ask questions about differences in the brains of individual persons. Sporns said this research could lead to clinical applications, offering new diagnostic tools for brain disor...

Brightening prospects of using fluorescent nanotubes in medical applications

...remove the most buoyant layer from the centrifuge, let it set for a while and then put it back in the ultracentrifuge for another 12 hours, the liquid separates into a number of distinct layers. The topmost layer has a purple color and, when analyzed, proves to contain a surprisingly uniform population o...

Researchers examine carbon capture and storage to combat global warming

...build good cars, we have driver training, we don't let children drive, we have laws against drunk driving-we implement a whole system to ensure that the activity is safe.'' Policy and progress Engineers have more than three decades of experience putting carbon dioxide into oil reservoirs, where i...

Understanding why C. difficile causes disease -- it's hungry

...at makes a hole in the organism’s cell envelope to let the toxins out. The last two genes are of greatest interest to Sonenshein and his colleague, Bruno Dupuy from the Institut Pasteur. One codes for a protein, known as R, that is necessary for the expression of the first three genes and the other code...

New research shows sharks use their noses and bodies to locate smells

...not discriminate between odor and seawater plumes, let alone targets. "These results demonstrate for the first time that sharks require both olfactory and lateral line input for efficient and precise tracking of odor-flavored wakes and that visual input can improve food-finding when lateral line info...

For many insects, winter survival is in the genes

...d adulthood. They used a laboratory technique that let them separate out genes that were turned on only in the flies in this dormant state. The researchers found 11 previously undiscovered genes that turn on heat-shock proteins during diapause. Until this study, they had only known of two such protein...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

... in exactly the same way, but what the fly does is let us find genes that are involved in the process, and then go figure out exactly how they are rewired to work in the human. The fly is really good for prospecting." ...

Despite their heft, many dinosaurs had surprisingly tiny genomes

...ct species' osteocytes had been. "These fossils let us sample species through evolutionary time," Edwards says, "providing genomic information that's often unavailable for long-extinct ancestors." ...

Bacteria control how infectious they become, study finds

... then turn on a select group of genes. These genes let disease-causing bacteria infect their host while at the same time protecting the bacteria from the host's immune defenses. “E. coli seems to prevent RfaH from acting unless the microorganism absolutely needs it,?Artsimovitch said. That's because b...

Is there a pilot in the insect?

...lized neurons to stimulate the wing muscles, which let the insects correct their flight and avoid crashes. Could these same neurons be used in a sort of "automatic pilot"? This is what Nicolas Franceschini, Franck Ruffier and Julien Serres have just shown. These biorobotics specialists from the Movement ...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...checking almost 1,200 interactions simultaneously let the researchers see the big picture of immune response, avoiding the contradictory results often produced by studies that focus on only a single biochemical pathway. To better understand their results, the investigators plugged their data into th...

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

...ically study single turnover," Collman said. "They let the enzyme have only one oxygen molecule and watch what happens." He said that single turnover is like taking a single photograph of an event, while steady turnover is like shooting a movie. Damaged enzymes Once Collman's group had solved the...

Lost dogs found more often than lost cats, study suggests

...et, they should get something visible out there to let people know about the missing animal." Lord says that many pet owners may not know how to go about finding their lost cat or dog. "For many of the owners in this study, it was the first time their pet had disappeared," Lord said. "Pet owners shou...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...ee the target molecule you’re looking for, you can let the beads capture the molecules on their surface, remove them from the liquid, and then just measure the number of molecules attached to the beads," said Nie....

Key found to kill cystic fibrosis superbug

...are very excited with these findings, as they will let us come up with novel molecules to disrupt the making of Ara4N," says Valvano. "These molecules could then be tested as novel antibiotics." Valvano is a Professor and Chair of the Department of Microbiology and Immunology, a Canada Research Chair in ...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

... in their simulations ?a "virtual microscope" that let them zoom in on previously invisible details -- is that initially the binding part of the enzyme moves freely and randomly across the cellulose surface, searching for a broken cellulose chain. When it encounters an available chain, the cellulose itse...

Anti-dandruff compound may help fight epilepsy

...ts of ZnPy caused the mutant potassium channels to let three times as much potassium flow through, raising the possibility of restoring normal nerve cell activity. “Most drug discoveries uncover chemicals that stop things from working - it’s a lot easier to close or block a door than open it,?Li says...

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

...dying the cells at the end of the process does not let you know what the series of changes were that caused the cells to become leukemic, and when they happened. "With the method we developed, we have duplicated the natural process every step of the way. The method we developed opens the pathway gen...

Researchers show that veins stiffen as we age

...n eight-minute period, and then slowly deflated to let blood escape from the limbs, the blood volume was measured, recorded, and graphed. The consistently lower blood volume under pressure pointed to the less springy veins of the older participants. Graphic courtesy of the American Medical Association ...

Heart smart: new drug improves blood flow

...t the causes to reliably identify and treat cases, let alone prevent these diseases," he says. "In up to 95 per cent of cases, the root causes of vascular diseases are still unknown. So clinicians have to rely on 'lifestyle' indicators and 'risk factors' such as high blood pressure and high cholesterol. ...
