DNA from feathers tells tale of eagle fidelity

...ature reserve in northern Kazakhstan. This reserve supports an unusual diversity of raptors and is home to no less than 24 different species of hawks, eagles, falcons, owls and harriers. Also participating in this study were Evgeny A. Bragin of the Naurzum State Nature reserve, Karamendy, Kazakhstan; and O. ...

Nanotubes inspire new technique for healing broken bones

...ve into the porous structure of the implant, which supports the new tissue as it grows to connect fractured bone segments. The new technique may someday give doctors the ability to inject a solution of nanotubes into a bone fracture, and then wait for the new tissue to grow and heal. Simple single-walled ca...

From a Few Wild Ancestors, a Citrus Cornucopia

...ybrids of these ancestral forms. The research also supports the generally held concept that most familiar citrus fruits -- including oranges, grapefruits, and lemons -- are actually hybrids. A Chosen Few Part of this can be explained by the fact that citrus, which is native to Southeast Asia, hybridizes rea...

AACR Favors 'full spectrum of stem cell research biology'

...o cause harm." At the same time, the AACR position supports the "ethical use of somatic cell nuclear transfer," noting that the technique, "promises to reveal the role of specific genetic alterations in tumorigenesis and further refine evaluations of drug activity, as well as generate immune-compatible materi...

Microbe has huge role in ocean life, carbon cycle

...licating "junk" DNA with no adaptive value - SAR11 supports that theory. Researchers are particularly interested in SAR11, Giovannoni said, because of the critical role it plays in geochemistry. Photosynthesis is a process used by plants to convert sunlight energy into organic molecules, creating the foundat...

Team of international scientists departs today to discover the unknown in China's Himalayan region

The fund will specifically be involved in this expedition to work with local eastern Himalayan scientists and students to identify as many specimens as possible. ...

Elderly mice yield clues to the process of growing old

...ow animals, including humans, grow old and die. It supports the theory that apoptosis or programmed cell death underpins aging. A competing theory holds that oxidative stress -- the body's reaction to oxygen and the production of reactive, cell-damaging molecules known as free radicals -- is responsible for t...

Stem Cells Found In Cerebellum; Possible Cell of Origin for Childhood Brain Tumors

...at stem cells actually exist in the cerebellum and supports the theory that medulloblastomas could arise from these cells, said the researchers. They hope their discovery will eventually lead to more targeted, less toxic treatments that disrupt the process by which stem cells could give rise to brain tumors. ...

However, neither study accounted for risk factors that contribute to HIV risk. Gray and his colleagues assessed 2,188 HIV-negat...

Evolution of taste receptor may have shaped human sensitivity to toxic compounds

...mful compounds found in nature. The work strongly supports a pivotal role for bitter-taste perception in toxin avoidance in humans, an attribute that could have come into particular play during periods of expansion into new environments. More broadly, the work contributes to the debate on the mechanisms gove...

Fat's fate depends on its source
