Helping chlorine-eating bacteria clean up toxic waste

...nswers, because the bacteria are hard to grow in a petri dish, said Ruth Richardson, Cornell assistant professor of civil and environmental engineering, who is following up on Gossett's and Zinder's work, in continued collaboration with them. She is partnering with Gene Network Sciences (GNS), a firm sp...

Researchers develop technologies to devour food pathogens

...gy." The process works by shining a laser though a petri dish containing bacterial colonies. A computer program determines the type of bacteria by analyzing how light is refracted-a unique "scatter pattern." Bhunia has shown his technology is capable of recognizing Listeria monocytogenes, a microbial pat...

Rescuing injured hearts by enhancing regeneration

...at they could coax cardiomyocytes to multiply in a petri dish by inhibiting an enzyme known as p38 MAP kinase, which normally suppresses cardiomyocyte replication.

Sex: It's costly but worth it. Just ask a microbe

...and flirting goes on when mixed pairs slide into a petri dish, and the results can be detrimental to their fitness. "We noticed that mating stunted their asexual reproduction because each partner spent more time attracting the other than nourishing its own growth," explains Xu. "Transmitting mating signal...

Breakthrough for stem cell research

...e used animal tissue to keep the hESC alive in the petri dish or as a culture to grow it on," said Dr Sidhu. "Those animal products have the potential to transmit retroviruses in humans, which could have disastrous consequences." Human embryonic stem cell lines are derived from specialized cells from emb...
