Researchers uncover beneficial mechanism of the helpful "Dr. Jekyll" side of the Cdk5 protein

Researchers at UT Southwestern Medical Center have uncovered new insights into the "Dr. Jekyll and Mr. Hyde" nature of a protein that stimulates stem-cell maturation in the brain but, paradoxically, can also lead to nerve-cell damage.

Researchers discover how Sonic hedgehog gene controls brain development

University of Pennsylvania School of Medicine researchers have discovered how the expression of the Sonic hedgehog gene is regulated during brain development and how mutations that alter this process cause brain malformations. The results appear online this month in Nature Genetics.

Novel cell division mechanism discovered

A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version of the journal of the American National Academy of Sciences, PNAS.

Research provides new insights into how cells accessorize their proteins

St. Jude Children's Research Hospital investigators have gained new insight into how the cell's vast array of proteins would instantly be reduced to a confusion of lethally malfunctioning molecules without a system for proteins to "accessorize" in order to regulate their function.

A fitness test for DNA

Unusually high levels of physical exertion do cause oxidative stress, but this does not result in any long-term damage to DNA. This is just one of the many outcomes revealed by an extraordinary research project funded by the Austrian Science Fund FWF that are now published. As part of this project, 42 male athletes took part both in a triathlon and an extensive biomedical study, which examined numerous physiological values parameters during the period from two days before to 19 days after the triathlon.
