Orchestrating change: Protein signaling between soybean root hairs, bacteria reveals core cellular processes

Understanding what happens to a soybean root hair system infected by symbiotic, nitrogen-fixing soil bacteria, Bradyrhizobium japonicum, could go a long way toward using this symbiosis to redesign plants and improve crop yields, benefitting both food and biofuel production. Because of their exte... Read More

Influenza H5N1 is not lethal in ferrets after airborne transmission

Ron Fouchier has discussed his influenza H5N1 transmission experiments in ferrets at an ASM Biodefense Conference, clarifying several assumptions about the transmissibility of the virus in this animal model. Read More

Earth’s virology professor

Nearly four months ago I stood at the front of a crowded classroom at Columbia University and began teaching the third year of my undergraduate virology course. Twice a week we discussed the basic principles of virology, including how virions are built, how they replicate, and how they cause dis... Read More
