Understanding that animal pathogens, like dangerous E. coli, cannot easily gain access inside the plant helps scientists know how to best combat bacteria that cause foodborne illness. It is important to know, he explained, whether food...

Scientists win grants to develop $1,000 genome sequencing technology

Xiaohua Huang, a professor of bioengineering in UCSD's Jacobs School of Engineering, leads the effort at UCSD to develop a promising technology that shrinks what is currently being done in large genome-sequencing laboratories down to a glas...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...mulating new bone formation can be done." Bone health is maintained by the balanced activities of osteoblasts and osteoclasts. The study shows that the inactivation of gene Atp6v0d2 in mice results in dramatically increased bone mass due to defective osteoclasts as well as enhanced bone formation. These...
