An international team led by Dr. Bernard Thébaud, Alberta Heritage Foundation for Medical Research Clinical Scholar, demonstrates that stem cells protect and repair the lungs of newborn rats.The study finds that rats treated with stem cells ran twice as far,

The copper sequestering drug tetrathiomolybdate (TM) has been shown in studies to be effective in the treatment of Wilson disease, a disease caused by an overload of copper, and certain metastatic cancers. That much is known. Very little, however, is

Darwin suggested that the action of natural selection can produce new species, but 150 years after the publication of "On the Origin of Species" debate continues on the mechanisms of speciation. New research finds sexual selection to greatly enlarge the

Advances in computerized modeling and prediction of group behavior, together with improvements in video game graphics, are making possible virtual worlds in which defense analysts can explore and predict results of possible military and policy actions, say University of Maryland

In three papers published back-to-back today in Science, scientists in a partnership between the European Molecular Biology Laboratory in Heidelberg, Germany, and the Centre de Regulacio Genòmica in Barcelona, Spain, provide the first comprehensive picture of a minimal cell, based

Whitehead researchers have developed a new approach for genetics in human cells and used this technique to identify specific genes and proteins required for pathogens. With the ability to generate knockout cells for most human genes, the authors were able

A new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires are closer to reality after a key discovery by researchers at IBM, Purdue University and the University of California at Los Angeles.

Intervals of regional warmth and cold in the past are linked to the El Niño phenomenon and the so-called "North Atlantic Oscillation" in the Northern hemisphere's jet stream, according to a team of climate scientists. These linkages may be important

Two prototype devices have been developed: one for efficient disinfection of healthy skin (e.g. hands and feet) in hospitals and public spaces where bacteria can pose a lethal threat; and another to shoot bacteria-killing agents into infested chronic wounds and

Journal of the National Cancer Institute) Long-term survivors of testicular cancer who were treated with cisplatin-based chemotherapy had more severe side effects, including neurological side effects and Raynaud-like phenomena, than men who were not treated with chemotherapy, according to a

Harvard University) A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals. The new approach, pioneered by bioengineers and immunologists at Harvard University, uses plastic disks impregnated with
