Researchers have now found evidence—in people and in algae—for a eukaryotic circadian clock that works independently of gene activity. This protein-based timekeeper might represent an evolutionarily ancient way of keeping cellular time.
Bioinformaticists describe in a paper published online this week by Science Translational Medicine a new technology that looks for mutations in the genes behind 448 childhood recessive diseases.
U.K. scientists report in this week's issue of Science (p. 223) that they have created transgenic chickens that can't pass on avian influenza, a disease that decimates poultry flocks and that flu scientists fear could spawn an influenza pandemic among humans.
ScienceNOW reported recently that young mollusks maturing in slightly warmer and more acidic seawater can't calcify their shells, the "placebo effect" may work even if patients know they are taking fake pills, people rely on the eyes to judge whether a face has a mind behind it, and DNA from an ancient finger bone has confirmed the discovery of a new type of human, among other stories.
Integrated data sets from two animal model organisms provide insights into the organization, structure, and function of their genomes.
Extensive analysis of the Caenorhabditis elegans genome reveals regions highly occupied by multiple transcription factors.
The Drosophila modENCODE project demonstrates the functional regulatory network of flies.
Virologist and Nobel laureate Luc Montagnier announced earlier this month that, at age 78, he will take on the leadership of a new research institute at Jiaotong University in Shanghai. Science talked to Montagnier last week.
