Antarctic Science Season Gears Up With Searches for Meteorites, Neutrinos, and New Life Forms

...d rise worldwide by six meters. West Antarctica's swift ice streams lie above a geologic rift -- an area where the earth's crust is pulling apart, possibly with profound effects on the ice streams' behavior, and hence on the ice sheet's overall stability. An aerogeophysical survey headed by Donald Blanke...

Insect defenses point the way to defeating bacterial antibiotic resistance

.... One reason for their success is their remarkably swift and effective system of defense against infections, which differs dramatically from the immune systems of higher-order animals, including humans.
