Artificial cornea offers better results for infants, some blind patients

...tificial implants for several years because of the poor results and high rates of complication. Meanwhile, Aquavella's former mentor, Claes Dohlman, M.D., of the Massachusetts Eye and Ear Infirmary, was evaluating new types of designs, eventually devoting decades to the project. When Dohlman unveiled a ne...

End of deforestation in view? Experts advance new way to size up global forest resources

...in obstacles to forest transition are fast-growing poor populations who burn wood to cook, sell it for quick cash, and clear forest for crops. Harvesting biomass for fuel also forestalls the restoration of land to nature. Through paper recycling and a growing reliance on electronic communication, people...

Drug can quickly mobilize an army of cells to repair injury

...ountered in diabetic patients, who can suffer from poor circulation in their limbs that causes pain or sores and may lead to amputation. The potential of the two drugs for treating such conditions was addressed in another study by the research group, also published in a recent issue of Blood, which teste...

Computer scientists unravel 'language of surgery'

...speech recognition program might call attention to poor pronunciation or improper syntax, the system being developed by Hager's team might identify surgical movements that are imprecise or too time-consuming. But to get to that point, computers first must become fluent in the "language" of surgery. This...

Transmission of antibiotic-resistant bacteria linked to previous intensive care unit room occupants

... may exist because of difficult-to-clean design or poor placement of hand hygiene equipment, transmission may be more directly linked to a prior occupant who harbors a resistant organism rather than to a particular room," the authors write.

T-beta-RIII joins the fight against breast cancer

... later stages of the disease are associated with a poor outcome. A study using human breast cancer samples and mice, which appears online on December 7 in advance of publication in the January print issue of the Journal of Clinical Investigation, indicates that changes in expression of one component of th...

'Empty nester' parent birds use recruitment calls to extend offspring care

...of nutritional independence. Because juveniles are poor foragers, they might benefit from staying close to experienced adults, who can find the best feeding sites. The new study shows that adult babblers continue to care for their young during this period. By observing the birds closely and performing s...

Two companies have shown interest in the process including one based in Mongolia. In research due to be publi...

How mammals fuel milk production may have implications for cancer

New way of tracking muscle damage from radiation

...helps us understand whether the blood supply is in poor or good condition," Krasin said. "Changes in T2 measurements may indicate an increase in swelling following radiation therapy, which is evidence of inflammation that could be treated." The researchers believe that the early changes they see in mus...

Math model predicts cancer behavior

...or's size and shape are evaluated, but they can be poor indicators of invasive potential: a very small tumor can be highly invasive. Even "molecular signatures" ?profiles of molecules that suggest how tumor cells will behave ?are not entirely predictive, he added. Quaranta and colleagues opted for a new...

Seagrass ecosystems at a 'global crisis'

Among its findings, the study analyzed an apparent disconnect between the scientific community’s concerns over seagrass habitat and its coverage in the popular media. While recent studies rank seagrass as one of the ...

Stem cells engage in dialogue with the cells that regulate their futures

...ightly controlled." Too little division results in poor maintenance of tissues, while too much can result in tumors or other malignancies. Her lab used the germline stem cell niche, found in the ovaries of fruit flies, as a model system. The production of fruit fly eggs depends on the presence of a ren...

Key to zebrafish heart regeneration uncovered

T-ray breakthrough could make detecting disease far easier

...plications are presently limited by the relatively poor ability to focus the rays, which is achieved using the conventional means of lenses and mirrors to focus the radiation. This limits the spot size of focused T-rays to a substantial fraction of a millimetre and this has made studies of small objects s...
