Scientists characterize proteome of human cornea

...urnal. The cornea is the transparent, dome-shaped window that covers the front of the eye. Although it is clear and seems to lack substance, the cornea is actually a highly organized group of cells and proteins. Its functions include shielding the eye from germs, dust, UV light, and other harmful matter an...

Many smokers fail to quit after cancer diagnosis

...ng motivator for many smokers and thus, provides a window of opportunity to begin treatment for smoking addiction. Led by Ellen R. Gritz, Ph.D., of The University of Texas M. D. Anderson Cancer Center in Houston, researchers reviewed the scientific literature to provide a comprehensive overview of smoking ...

Purdue's gold nanorods brighten future for medical imaging

...of the spectrum called near infrared. "There is a window of light in the near infrared, wavelengths from about 800 to 1,300 nanometers, which could be harnessed for new imaging technologies," Wei said. Tiny gold rods with a certain "aspect ratio" of length to width shine brightly when illuminated by light...

Researchers develop new testing methods for potential monkeypox or smallpox outbreak

...percentage of unconfirmed cases due to the limited window of opportunity for diagnosis. In comparison, OHSU's research team tested samples using a variety of methods. One such test, called the ELISA test, resulted in very accurate results (95 percent sensitivity, 90 percent specificity.) This high level of ...

Genetic variation alters response to common anti-clotting drug

...drug challenging to prescribe. "There is a narrow window between too much and too little effect," explained Rettie. "A small change in dose can have quite a large effect on blood processes." For example, too high of a dose can result in excessive bleeding while too little of a dose could allow dangerous bl...

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

...e, which can last several minutes, may represent a window of opportunity for drug development. The remarkabl... lasts several minutes, giving us an adequate time window for drug action." ...

Tagging pathogens with synthetic DNA 'barcodes'

...ow cytometer, in which samples move rapidly past a window where a computer reads the color codes of individual beads. Another is by dot blotting, in which the sample is spread on a sheet of absorbent paper and made visible to the naked eye. Or the color can be observed directly through a fluorescent light m...

Micro-molecule plays big role in birth defects

...stage in the developmental process, thus opening a window into the role of microRNAs in limb development. In cases where Dicer is not present in developing limb tissue, Harfe showed that microRNAs were not processed and limbs were visibly smaller. "Many of the birth defects we see in people are mimicked b...

Spider blood found in 20 million year old fossil

...ce of amber with a single spider in it can open up window into what was going on 20 million years ago. "By analysing the position of the spider's body in relation to the droplets of blood in the amber we are able to determine how it died, which direction it was travelling in and even how fast it was moving...

'Punctuated' evolution in the human genome

...romeric region occurred during a relatively narrow window of evolutionary time between 10-20 million years ago. This corresponds to the time period following the divergence of humans and Old World monkeys, but before the divergence of humans and great apes. For the past 10 million years, however, no such "d...

Gifts from the sea

...lam eggs are also transparent, providing a perfect window on biology in action. MBL scientists studying surf clams have made discoveries that may be critical to understanding diseases such as cancer; progeria, a disease that causes children to age unusually quickly; and muscular dystrophy. For a list of MB...

Researchers feed tiny pills of RNA to planarians to identify genes essential for regeneration

...stitute investigator. "This work opens a whole new window to study aspects of human biology that are barely accessible today." The planarians used in these studies, also called flatworms, live in fresh water and have a singular ability to regenerate. Chop one in half, and two new worms grow. Their ability ...

Scientists discover odd-ball rodent

...e it is an indication of how little we know, and a window onto what we could be losing without ever knowing," said Dr. Timmins. ...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...the Canada Basin. "Modern technology has opened a window on this amazing world for the first time," says scientist Dr. Russ Hopcroft of UAF. "The imagery obtained of the mid-water and seafloor shows many life forms, such as soft bodied zooplankton, deep sea cucumbers and soft corals. The few explorers in t...

Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils

...gi," Xiao said. "The Doushantuo Formation opens a window into ancient marine life. There is a lot more remains to be learned from these rocks," Yuan added. ...

Disabling gene defuses rheumatoid arthritis in mice

...entified role for the gene, Foxo3a, may open a new window for treating arthritic conditions caused by immune dysfunction. Currently, most treatments in development for these disorders focus either on preventing wayward immune cells from attacking the joints or on reducing the ability of these cells to open ...

Molecular thermometers on skin cells detect heat and camphor

...ts bubble of cerebrospinal fluid, it has no direct window to the outside world, so the only way for the brain to observe, comprehend, and order the body into action is to rely on information it receives. This information comes to it through a sophisticated system of sensory neurons that connect the brain to...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...ike found that immediately following each one-week window in which much of the valley was irrigated, there was a response in the ocean off the coast of the Yaqui Valley," Matson explained. "We were quite surprised," Arrigo added, noting that the Nature paper marks the first time that scientists have docume...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

...which means that there is a particularly important window of opportunity for gene therapy in infants," Wolfe said. "In our study, we could see that gene therapy used during this particular time led to a restoration of damaged neurons, even though the lesions that represent the disease were already extensive...

Study reveals new technique for fingerprinting environmental samples

...lar utility is that it offers an easily accessible window into that important part of the biosphere with significant impact on the environment. DOE JGI postdoctoral fellow Susannah Green Tringe was first author on the Science paper that, in addition to other DOE JGI scientists, included collaborators from ...
