Satellites play vital role in understanding the carbon cycle

... sensitivity down to the Earths surface because it observes the spectrum of sunlight shining through the atmosphere in nadir looking operations on a global scale. Buchwitz explained that he and his colleagues first measure the absolute carbon dioxide (CO2) column in number of CO2 molecules per area above t...

Glucose triggers brain cell death in rats after hypoglycemic coma

...s put in." In terms of clinical science, Swanson observes that "as clinicians, our first reaction when we see a patient in hypoglycemic coma is to give lots of glucose, fast. But our rodent model makes it clear that overshooting glucose levels is very bad for rat brains. The way we treat patients for hypogl...

Fatal attraction: Elephants and marula fruit

...cessful "In fact, elephants are crazy about them!" observes Dr Hemborg "They spot the Marulas from far and walk long distances to feed on fruits, foliage and bark." The research shows that the female Marula suffers a higher risk than the male tree of being destroyed and perhaps killed by elephants. "There is ...

U-M team: Genetic testing sheds light on degenerative eye disease

...s advantage to have a molecular diagnosis on file, observes Ayyagari. When treatments begin to emerge for these complex genetic diseases, she says, the individuals genotype may determine whether a new treatment will be the one that works for that patient....

Cholera pathogen reveals how bacteria generate energy to live

...lectron Paramagnetic Resonance Spectroscopy, which observes electron spin, she and her co-worker Mark Nilges at the University of Illinois analyzed the properties of the flavin molecules, and mapped these functional properties to specific points in the protein structure. NQR is only one of several sodium pu...

Unique imaging uncovers the invisible world where surfaces meet

...ing madly In a second imaging project, Hirschmugl observes the arrangement of specific molecules on a solid surface, again enlisting the wave properties of electrons. "What we are looking at is way smaller than the wavelength of light," says UWM physicist Dilano Saldin, who collaborates with Hirschmugl. "I...

Distinguishing friend from foe in the battle against cancer

...res higher and higher doses of chemotherapeutics," observes Verma, who is also an American Cancer Society professor in Salk's Laboratory of Genetics. "Rapamycin-mediated killing of cancer cells could be increased by inhibiting the function of NF-kB proteins. Our studies provide the basis for arriving at this ...

Miscarriage significantly associated with increasing paternal age

...en are more susceptible to certain birth defects," observes Dr. Klienhaus. In fact, the American Society for Reproductive Medicine has set an upper age limit of 40 years old for semen donors because of the increased risk of genetic abnormalities in the offspring of older fathers. The international team ...

Eavesdropping fringe-lipped bats spread culture through sound

...tor five times. Page and Ryan believe the nave bat observes the tutor's location through echolocation and then listens to it chewing on its prey. "There have been many of studies on diet and learning, but most have been conducted with laboratory animals," said Page. "This study is exciting because we are taki...

Satellite instrument helps tackle mysteries of ozone-eating clouds

...lected by MIPAS, a German-designed instrument that observes the atmosphere in middle infrared range, Hpfner and other scientists discovered a belt of nitric acid trihydrate (NAT) PSCs developing in the polar night over Antarctica in 2003 about one month after the first PSCs, which were composed of water cryst...

Flying tip of bees: Leave your legs dangling!

...de or often upside down, and crash to the ground", observes Combes. This means that what limits the bee's speed is not muscle power or the amplitude of its wing beat, but the pitch of the body balanced with the resulting rotational instability. "Having the legs extended generates stabilizing lift forces and ...

University of Kentucky author captures national attention with 'Lost Mountain'

...trip mining and religion. In "Lost Mountain" Reece observes the systematic obliteration of a peak located in the middle of what scientists regard as the North American rainforest because of its remarkable density and diversity of plants, birds, and animals. The mountain was also situated in Eastern Kentucky, ...

Genetic key to growth of new arteries is identified

...sponse to an arterial blockage and others do not," observes Sarkar, who is also an assistant professor of surgery at the University of California, San Francisco. "So it's very important to understand the normal process that allows an animal or a person to grow new arteries when their legs don't get good blood...

Coming to grips with robot learning

This is optimise...

High doses of vitamin E boost rat survival rate 40%; brain function, neuromuscular gains

...er 400 patients without adverse effects. The paper observes that the "study shows the beneficial effects of high doses of vitamin E on the median and maximal lifespan of male mice, an effect that is parallel to a beneficial effect on the decline of neurological performance and mitochondrial function associate...

Photos reveal new primate species

... is very small and limited in distribution. Ehardt observes that, "With the addition of another threatened species of primate to those species previously documented, the Udzungwa Mountains are arguably the most important site in Africa for primate conservation. The Udzungwas remain a focus for conservation e...

Researchers discover mechanism for multiplying adult stem cells

...allow you to expand adult stem cells for therapy," observes Hochedlinger. "For instance, you could remove a person's skin tissue, put it in a dish, isolate the skin stem cells, then subject it to an environment that activates Oct4. This would cause the cells to multiply yet remain in their stem cell state. An...

Autism linked to mirror neuron dysfunction

...hen a monkey performs an action itself and when it observes another living creature perform that same action. Though it has been impossible to directly study the analogue of these neurons in people (since human subjects cannot be implanted with electrodes), several indirect brain-imaging measures, including E...

Monaco formalises its EUREKA membership in Paris

...elopment both economically and to generate jobs," observes Vieillefosse. "Monaco sees EUREKA as one of the most effective tools to reach its objectives." After the Vatican, Monaco is the smallest country in the world, with a population of 32,000. Over 25,000 people commute into Monaco every day, mainly from ...

Open microfluidic and nanofluidic systems

... to fill these channels with a certain liquid, one observes that the liquid often refuses to enter the channels. In fact, as shown in the new PNAS study, liquids at surface channels can attain a large variety of different wetting morphologies including localized droplets, extended filaments, and thin wedges a...
