Liquid ventilation

...s stress and respire more easily. However, this story does not have a happy ending. The respirator, for the moment, is no more than a prototype. In the experiments carried out at the Cruces hospital in Bilbao with artificial lungs and with animals, the results have been very good. It has even been appli...

Wisconsin scientists discover a master key to microbes' pathogenic lifestyles

...a new environment: the lungs of animals. "It is a story of how organisms are challenged in a new environment," says Klein. "They have to make themselves over so they can survive."...

Cancer support cells may evolve, fuel tumor growth, study shows

...cell. The new findings are published as the cover story in today's (Dec. 16) issue of the journal Cell.While not offering immediate application to the treatment of human cancers, the research indicates that new anti-tumor therapies may be more effective if their targets are broadened to include molecules ...

Image of myosin-actin interaction revealed in cover story of Molecular Cell

...nd structural biologists was selected as the cover story for the September issue of the scientific journal Molecular Cell. The Burnham team, led by Dorit Hanein, Ph.D., was the first to reveal the 3D representation of myosin V "walking" along actin filament, a key protein involved in motility and muscle c...

Science's Breakthrough of the Year: Watching evolution in action

...e a more immediate impact on medicine. The amazing story of flu genes preserved in permafrost and painstakingly reconstructed has a chilling coda: the deadly flu seems to have started out as purely a bird virus. Understanding the evolution of last century's deadly bird flu may help us predict and cope with...

Independent researchers confirm the existence of ivory-billed woodpecker

Editor : Link to our previous story about the discovery After reviewing new sound recordings from the White River of Arkansas, an independent team of ornithologists has confirmed the existence of the Ivory-billed Woodpecker. Working from previously unpublished data provided to them...

The conference, which will be held in dialogue format, will feature ...

Research casts doubt on circulating stem cells

...rrow is generally blood and not muscle tissue. The story of a "jack of all trades" circulating via the blood stream throughout the body and repairing, wherever needed, any type of tissue is, unfortunately, a myth. In practice their impact is, at best, minimal. The somatic cells mark genetic traits believe...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...icroscopy and image processing. Levin told him the story of Chagas and the need to know more about the structure of the parasite's ribosome. A ribosome is basically a double ball made mostly of RNA and over 50 proteins. The balls, which are of unequal size, are called small and large subunits. After a str...

Geckos: It's not always about sex

...netically identical to her. A further twist to the story is that many parthenogentic species, including the Bynoe's gecko, evolved when two species crossed, or hybridized, said Michael Kearney. He is a postdoctoral research fellow in the Centre for Environmental Stress and Adaptation Research at the Univer...

Fundamental discovery -- Bone fracture

"So the emerging story is that RAR1 and HSP90 keep resistance proteins ready to perceive pathogen signals, and SGT1 probably pulls against these two to send resistance proteins to their destruction." The National Science Foundation supported the research through its Arabi...

"As a wetland gets older, it gets better at handling and storing nitrogen," Mitsch said. "The idea is not to overload wetlands in the first place." The three-acre we...
