Atmospheric ozone recovering in mid-latitudes, report shows

...one-monitoring systems. "We do think we're on the road to recovery of stratospheric ozone, but what we don't know is exactly how that recovery will happen," said Derek Cunnold, a professor of earth and atmospheric sciences at the Georgia Institute of Technology. "Many in the scientific community think it...

Tiny shock absorbers help bacteria stick around inside the body

...r car that dampen turbulent forces caused by bumpy road conditions," added study co-author Dr. Wendy Thomas, assistant professor of bioengineering at the UW. The researchers found that fimbrial uncoiling and recoiling events balance each other at an intermediate force level that corresponds to the force...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

...ens every once in a while. If I'm running down the road and I trip, that would be a random phenomenon. But if I run down the road and every time I trip there's a pothole, then that's not random." Some researchers have argued that...

Invasive species alter habitat to their benefit

...human activity, such as the use of fertilizers and road salt and the suppression of natural wildfires, also may result in environmental changes that affect species diversity. "My question was, are humans causing the changes, or are the invaders?" Farrer said. "Finding the answer has practical implicatio...

China's environmental challenges

...thors wonder: will China "?.continue down the same road as in the past two decades, or will environmental quality, energy efficiency, and the conservation of resources no longer be sacrificed at the altar of economic development?" Authors Wei An and Jianying Hu (Peking University) tackle the topic of end...

Cardiologist's 'living chip' changes science of disease monitoring

...chnology that is minimally invasive. We are on the road to doing this." Promising technology Physiologic Communications, created 18 months ago by Rosero, has quickly grown from an idea to a successful start-up venture thanks in part to Excell Partners Inc. The Rochester-based consortium assists young co...

Molecular mechanism provides intra-cellular traffic signal

...ular compartments -- much as vehicles on a crowded road are allowed to pass quickly through a succession of green traffic lights. The molecular mechanism that underlies this coordination is reported by lead researcher Nava Segev, UIC professor of biological sciences, in the November issue of Nature Cel...

UCSD researchers create roadmap to integrin activation

...e wall of blood vessels and to one another. "The road map of the activation pathway could lead to the development of new antithrombotic drugs or treatments for inflammatory diseases. In addition, the ability to engineer these activation pathways may contribute to efforts to develop artificial platelets...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

... genomic technologies, is an important step on the road to developing practical, biologically-based substitutes for gasoline and other fossil fuels." "Biofuels are not only attractive for their potential to cut reliance on oil imports but also their reduced environmental impact," said Dr. Gerald A. Tusk...

The biggest bug in gut discomfort

...C. jejuni disappear off the conventional endocytic road map" Robert Watson and Jorge Galan of Yale University School of Medicine report that C. jejuni apparently rolls in on the cell’s regular endocytic pathway but quickly exits, heading off-road for its own network of intracellular hideouts. These C....

Regulating the nuclear architecture of the cell

...gulation, just as Su(var)3-9 mutants did. The road to regulation One effect of both Su(var)3-9 and RNAi mutations was to increase the amount of extrachromosomal DNA, typically small loops of repeating sequences, in cell nuclei. This observation led Karpen and Peng to propose a specific mechanism ...

End of the road for miglustat The latest promising contraceptive that didn't make the leap from mice to men is miglustat (trade name Zavesca) (Human Reproduction, Oct. 25). The drug is already FDA-approved and on the market in both Europe and the United States f...

Fruit fly gene research may shed light on human disease processes

"Scientists have been trying to understand how the sex of mosquitoes is determined, with an eye to eradicating those which carry diseases," he says. "Our research on fruit flies may help in this que...

Light-based probe 'sees' early cancers in first tests on human tissue

Motor protein plays key role in connecting neurons

A motor protein called myosin X runs the main road of a developing neuron, delivering to its tip a receptor that enables it to communicate with other neurons, scientists say. In another piece of the puzzle of how neurons form connections, researchers have found myosin X travels a portion of a neu...

Mimicking how the brain recognizes street scenes

...ection, such as: if I see a car, it must be on the road not in the sky. Giving the model the ability to recognize such semantic features will empower it for broader applications, including managing seemingly insurmountable amounts of data, work tasks, or even email. The team is also working on a model for...
