Understanding how primitive organisms like Nanoarchaea operate gives clues to -- but not proof of -- the relationship between modern and ancient organisms. ### Other authors on the paper include Lennart Randau and Michael...U-M scientists find genes that control growth of common skin cancer

Inadditional studies, the researchers found that regressing BCC cellscould be reprogrammed to differentiate into various epithelial celltypes, ultimately capable of assembling fully-formed hair follicles.These results suggest that BCCs contai...Purdue proves concept of using nano-materials for drug discovery

The chips could dramatically increase the number of experiments that are possible with a small amount of protein.

...ifically looked at small, hairlike structures that exist on most cells. They found that the shape and size of these hairs, or trichomes, readily show when genes affecting actin filaments are askew and causing altered growth. The researchers previously had learned that a large protein complex, known as WAV...Protein discovery could unlock the secret to better TB treatment
...ing factor (Rpf). Five versions of the Rpf protein exist in TB bacteria. The paper's unveiling of the molecular structure of Rpf could be crucial to the treatment of TB in the future. Dr John Ward, Dept of Biochemistry and Molecular Biology at UCL, said: "The discovery of Rpf in the TB bacteria could allo......t the full repertoire of reproductive hormones can exist at birth, go into hiding at about four to six months of age, then reemerge in full force some 10 to 12 years later? "Puberty is critical to human development. And while there is a fairly good understanding of how the endocrine system regulates the h...
