have so far been restricted to mice, the presence of such cells in the skin holds promise for regenerative medicine with regard to hair loss and wound healing, the researchers added. Once the essential genetic differences that distinguish embryonic a...
Optimizing protein's 'death domain' halts leukemia in laboratory study
...uthor. Korsmeyer and his colleagues have pioneered studies
of apoptosis, or programmed cell death, that rids the body of damaged or unneeded cells. Apoptosis is directed by a complex collection of proteins in a yin-yang-like balance and is activated by a variety of external and internal signals. Some of the ...
The birth of a beak
...in a variety of finch species. Together, these two studies
are able to point to BMP4 as having a major role in the creation of the avian beak, demonstrating that it is "one of the major driving forces building beak mass." "By 'tinkering' with BMP4 in beak prominences," Chuong and his scientific colleagues wr...

with Richard Roberts of the California Institute of Technology. Cells are basically sacs encapsulated by bilayered membranes of fatty acids and other lipids, plus proteins. A central question in evolution is how simple versions of these cells, or ve...

in the September 3, 2004, issue of the journal Science. The chemical approach they applied, called hydrocarbon stapling, was developed by their collaborator Gregory L. Verdine of Harvard University, and permitted the researchers to overcome the te...
Analysis fingers causes of desertification
... Change International Project, considered 132 case studies
of dryland degradation. The results challenge single-factor explanations that put the most of the blame for desertification on the rural poor and nomadic populations. Nor do the results support the notion that desertification is the result of irreduc...
