Could polar bears in the wild interbreed with brown bears, their evolutionary close cousins, as has occurred at least once in captivity? What impact will grizzlies, already known t...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

...plied to humans, say the researchers, it might one day treat an entire class of diseases called lysosomal storage disorders which cause severe, sometimes fatal, disabilities in about one in 5,000 births. The members of the research team from the University of Pennsylvania School of Veterinary Medicine, t...

Red delicious, Northern Spy apples have most antioxidants, chemists find

...the human equivalent of one, three or six apples a day respectively over 24 weeks were up to 44 percent less likely to develop breast tumors. That study was published in the April 6, 2005, issue of the Journal of Agricultural and Food Chemistry. ...

Cellular Defects in Premature Aging Disease are Reversible

...meaning his laboratory's method could be used some day in the future as a therapeutic strategy. The fact that a progeria reversal can be achieved in multiple cell types, and that the cells can return to normal, independent of cell division, bolsters this possibility. "Some tissues in our body do not divi...

Brain May Be Less Plastic Than Hoped

... brain, Smirnakis added. Similar studies could one day show scientists how to help the brain to recover from injuries. “In humans, studying brain reorganization is difficult. Cortical injuries are not happening in a controlled fashion, and resulting data consequently are difficult to interpret,?he said. ...

Nature provides inspiration for important new adhesive

...ssistant professor, who was harvesting mussels one day from their rocky home at the ocean's edge. Li observed mussels being pounded by ocean waves, and wondered how they could cling so tenaciously to rocks by their thread-like tentacles. "I was amazed at the ability of these small mollusks to attach th...

The skeleton in the exhibit will be assembled from the fiberglass casts so that researchers can continue studying the real bones, which are on loan to the museum from t...

Some Brain Cells Change Channels

...t let researchers harness the process, perhaps one day using it to protect cells that die in Lou Gehrig's disease. Much as turning the television dial changes what comes into the living room, these brain cells are able to change what they allow in by swapping one kind of channel, or membrane opening, fo...

Newly discovered protein an important tool for sleeping sickness research

...its antigen coating, the discovery of JBP2 may one day enable scientists to create a drug that prevents the manufacture of base J, affecting the trypanosome's ability to vary its antigenic coating, and therefore allowing the human immune system to kill it. Understanding trypanosomes at the molecular lev...

Researchers Closer To Helping Hearing-Impaired Using Stem Cells

...School of Medicine are several steps closer to the day when a profoundly deaf patient’s own bone marrow cells could be used to let him or her hear the world. The IU group, led by Eri Hashino, Ph.D., was able to transform, in the laboratory, stem cells taken from adult bone marrow into cells with many of...
