Salty oceans provide early warning for climate change

...e a pocket of water becomes salty enough it sinks, drawing in additional water from surrounding areas, and initiates an ocean circulation loop called thermohaline overturning. The scientists discovered that a build up of salt in the waters off the coast of South Africa could help to speed up ocean circula...

Students invent protective pouch to enhance cell therapy

... to solve a real-world engineering challenge while drawing on the expertise of prominent researchers such as Arepally and Bulte. "I don’t think I could have found an opportunity like this anywhere else," he said. "That’s one of the major strengths of Johns Hopkins." Link plans to continue working on the proj...

Man's best friend lends insight into human evolution

Flexibly drawing inferences about the intentions of other individua... But it turns out that chimps are not very good at drawing inferences about others' mental states in cooperative situations ?such as when an experimenter (or a...

Risk of HIV transmission highest early in infection

...mission through phylogenetic analysis—essentially, drawing the virus’s family tree. The technique follows the history of a virus as it spreads from one person to another by looking at the evolution of viral genetic material in infected individuals. Drs. Brenner, Wainberg, and colleagues found that 49 per...

Scripps research study shows humans and plants share common regulatory pathway

...pathway in mammalian cells as well as the value of drawing on plant studies of R protein pathways to better understand the pathogen recognition functions of these proteins." The Nod proteins recognize invasive bacteria, specifically distinct substructures found in Gram-negative and Gram-positive organism...

LIAI completes world's most comprehensive analysis on influenza virus data

...y and T cell epitopes published to date worldwide, drawing from the NIAID's Immune Epitope Database, a new worldwide scientific resource that went public last summer. LIAI researchers developed the database ?which is the world's largest repository of scientific data on how the body's immune system responds ...

Fighting to keep Darwin in the classroom

...h opened at the AMNH in New York in November 2005, drawing in over 500,000 visitors. Greg Eldredge has a Masters Degree in Education and has been a New York City school teacher for the past three years. He is a co-author of the children's book The Fossil Factory. The two are supported by an international ...

Mosquito genes explain response to climate change

...y must do to survive. "This chromosomal map is drawing a lot of interest in terms of understanding the genetic response of animals to rapid climate change and also to understanding the metabolic processes involved in disease intervention in humans and other complex organisms," Holzapfel said. Bradshaw...

The connector rotation hypothesis? Phage do not pack their DNA by rotation

...ing of ATPases alternately compresses and extends, drawing in the DNA. But further testing will be needed to confirm the validity of that model to the degree of certainty with which this team rejected the rotator hypothesis. ...

Vanishing beetle horns have surprise function

...may prevent yourself from making big mistakes when drawing up evolutionary histories. In this case, I think we did both." ...

Mysterious 'neural noise' actually primes brain for peak performance

...ysteriously, properly calculated. The science of drawing answers from such a variety of probabilities is called Bayesian computing, after minister Thomas Bayes who founded the unusual branch of math 150 years ago. Pouget says that when we seem to be struck by an idea from out of the blue, our brain has act...

Jefferson scientists find high glucose before surgery raises risk of dangerous complications

...current study was retrospective, Dr. Mraovic says, drawing firm conclusions from the results can be difficult. The findings need to be confirmed in a randomized, prospective trial. He would like to next find out whether controlling blood sugar before and during surgery could actually result in a lower ris...

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

...t may also send signals to other cells in the body drawing them to the injured area to help in repair, Mishra theorizes. Early studies have shown PRP therapy to be useful in maxillofacial surgery, wound healing, microfracture repair, and in the treatment of plantar faciitis. Treatment with PRP is still con...

A giant among minnows: Giant danio can keep growing

...e to allow them to do physiological research while drawing on the knowledge base of the zebrafish genome. The researchers saw the giant danio as the physiological model and began a series of experiments on differences in muscle growth between the fish. In this two-phased experiment, they discovered that th...

Researchers add to understanding of how brain cells communicate

...rrently limited understanding of NR1/2D receptors, drawing a direct link to human disease and memory is speculative, but I am confident that the links will become firmer as research progresses," Johnson said. ...

MIT engineers probe spiders' polymer art

...ally spin ("spinning" refers to the age-old art of drawing out and twisting fibers to form thread); instead, they squirt out a thick gel of silk solution. (One teaspoonful can make 10,000 webs.) They then use their hind legs as well as their body weight and gravity to elongate the gel into a fine thread. K...

Scientists describe new African monkey genus ?first in 83 years

...ind the new findings was remarkably collaborative, drawing on the expertise of a team of scientists spread around the world. Davenport, the lead author, Daniela De Luca, Noah Mpunga and Sophy Machaga, also co-authors, work for the Wildlife Conservation Society and are founders of the Southern Highlands Conse...

UF scientists restore sight to chickens with blinding disease

... how we operate. So I did this simple little test, drawing little dots on a piece of paper. The chick, which was standing on the table, came over to the paper and started pecking at all of them. It was so exciting." Later, more precise tests showed that of the seven treated chickens, five displayed near-nor...

It's all in the genes

... "This is an exciting project with global impact, drawing on the expertise of geneticists, ecologists, molecular biologists, biogeographers and others," said Chris Greer, program director at the National Science Foundation. "The results are expected to not only shed light on how complex biological communiti...

A catalogue of proteins

...elles in cells using microscopic methods, and then drawing conclusions about their function. Biochemical methods have allowed scientists to examine the inner life of the cell, an organisational unit basic to all life. Now, they are clarifying its structures in detail: from mitochondria, the "factories" of ce...
