Biologists ID defense mechanism of leading fungal pathogen
...fungal pathogens like Aspergillus -- a more deadly species
than Candida -- use the same NO defense. Gustin said Aspergillus has two genes that are good candidates for study, and he plans to begin research on them in the fall. The research was supported by the National Science Foundation. Co-authors of the st...
Researchers recommend new approach to combat drug-resistant staph infections
...tion." RIP has been shown to inhibit any strain or species
of staphylococci so far tested, including antibiotic-resistant strains, and no resistance to RIP has so far been observed. RIP has also been shown to be synergistic with antibiotics, so it can be used in combination therapy. RIP prevents the bacteria...

Stem cells commit to a future of fat with one signal
...ns will likely have human counterparts, since both species
have very similar proteins and developmental pathways. "There are likely to be many genes involved in commitment to fat-cell development," says Lane. "The key ones will likely be turned on early in the game, and hopefully we'll be able to detect them...
Scientists discover new role for tiny RNA in plant development
