...ell death is how the plant keeps the pathogen from spreading to other cells," Kamoun said. "Only a few cells die. It's one mechanism of defense some plants have." Until now, researchers knew little about P. infestans on the molecular level. By studying Avr3a, R3a and similar genes, researchers may be able to...Road salt affects mitigation wetlands

Resistance to antibiotics is spreading dangerously among bacteria, some of them being resistant to all known medicine. To face this challenge, a radically novel line of attack consists in disorganizing infections, instead of killing individual bacteria.
