Mechanism for the captation of nutrients in plants- unknown to date

...in plasma membranes, their number and relevance is considerably inferior to what has been believed to date. In the absence of saccharose, nutrients can penetrate the cell by means of transporters, but the amount entering through this mechanism is less than that incorporated via endocitosis. Thus, the experiments...

First production of human monoclonal antibodies in chicken eggs published in Nature Biotechnology

"Furthermore," Dr. Kay continued, "unlike other transgenic animal systems, the time from antibody identification to production in eggs can ...

Elevated temperature enhances success of viral cancer therapy

...y for many cancer patients, but the success varied considerably for reasons that were not well understood. Dr. Clodagh C. O'Shea and colleagues from the Cancer Research Institute at the University of California, San Francisco examined why ONYX-015 did not undergo replication in some cancer cells and if it might b...

Study shows eutrophic lakes may not recover for a millennium
