Ebola virus: from wildlife to dogs

...tes, once infected, soon die of the disease. Their bodies then become a potential source of contamination for humans, but also for certain domestic animals. Ebola virus antibodies were detected in dogs exposed to the virus during the latest epidemics, which suggests that these animals may well have been inf...

U.N. mulls the protection of Earth's forests

...t Catherine Karr Colque, recommend world governing bodies recognize the importance of forests to countries' long-term sustainable development, and urge states to integrate forest policy into their long-term development plans. This report was written with support from Indiana University and the U.S.D.A. Fore...

Unlike other mammals, newborn dolphins and orcas stay active 24/7 during first months of development

...r Los Angeles Healthcare System, Sepulveda. "Their bodies have found a way to cope, offering evidence that sleep isn't necessary for development and raising the question of whether humans and other mammals have untapped physiological potential for coping without sleep." Researchers observed two adult femal...

Researchers reveal secrets of flying snakes

...ucture, unlike these flying snakes that whip their bodies through the air. "Although all of these other animals may make small adjustments while gliding, none are as dramatic, rhythmic and dynamic as the flying snake," Socha said. During his first study, published in Nature in August 2002, Socha described ...

Researchers grow stem cells from human skin

...niversity Baptist Medical Center. "The bulk of our bodies is made up of fat, muscle and bone." The promise of stem cells lies in their ability to develop into specialized types of cells and to replicate themselves. Scientists hope to harness the potential of stem cells and use them to replace damaged cells...

Newly discovered genetic disease sheds light on body's water balance

Two infant boys whose bodies were overloaded with excess fluid have led UCSF pe... as an osmotic agent. As water flowed out of their bodies and sodium concentrations returned to normal, both babies recovered. They continue to be followed by...

Purdue scientists may have found key to halting spinal cord damage

...crolein that these attacks release survives in our bodies much longer, for several days at least, and its toxicity is well documented." For example, acrolein has long been known to cause cancer when its concentration in the body rises, and not much is needed to be dangerous. When a person inhales smog or t...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

Sandia completes depleted uranium study

...ffects of DU fragments embedded as shrapnel in the bodies of some U.S. veterans. The Sandia study also looked at civilian exposures in greater detail, examined the potential risk of DU-induced birth defects in the children of exposed individuals, and provided a more detailed analysis of the dispersion of DU...

When a trace sufficiently matches a pictogram in the human dataset, it triggers a real-time bioinformatics comparison: BLAST begins to run, searching through the rice data for...

What comes first…the chicken, the egg, or the bad attitude?

... to shift their nutrients from the growth of their bodies to egg production, but some of them don't do it very willingly. It is not a conscious thing the bird does, but it does express a tendency of that bird to either be generous or to be selfish with its nutrients." Channelling food into body-building re...

Industrial contaminants spread by seabirds in High Arctic, new Canadian study shows

...ants as well. The contaminants accumulate in their bodies and are released on land." The study took place at Cape Vera on northern Devon Island in the Canadian High Arctic, far from industrial and agricultural sources of pollutants. However, chemicals are emitted into the air and oceans from the populated ...

Tadpole soon to help in the fight against cancer and lymphedema

Lymph circulates in our bodies through a complex network of lymphatic vessels, of which little is known. This network is, however, of major importance for the support of the immune system and the fluid in our body. Researchers from the Flanders Interuniversity Institute for Biotec...

Toxic flood lifts lid on common urban pollution problem

Broken sewers, flooded industrial plants and dead bodies are all likely to blame for poisoning the waters being drained from New Orleans. But the water - and the muck it is leaving behind -- also owes its contamination to a source as mundane as it is unexpected: Toxins common in most urban environments th...

Scientists use gene transfer technology and common virus to block neuropathic pain in animals

... through the axon back to the sensory ganglia cell bodies next to the spinal cord,?says Shuanglin Hao, M.D., Ph.D., a U-M research investigator and first author of the study. “Since the vector lacks essential viral genes for replication, it remains in the nucleus expressing the GAD enzyme, which triggers n...

Disappearing arctic lakes linked to climate change

...ratures lead to increased numbers of surface water bodies in the colder permafrost regions. Many lakes decreased in size or dried up completely, while other lakes actually increased in size. Researchers say as the climate warms, additional meltwater accumulated in the lakes located in the colder regions of...
