Clues to future evolution of HIV come from African green monkeys
...rom the 2000s, Worobey added, "For HIV, the really cool thing is that these changes can take place on a more rapid timeline that previously thought."

... to study sea anemones. "These creatures were so cool simply because we knew that no sea anemone had ever been found on a whale fall," she said. Once a whale dies, its carcass sinks to the bottom of the ocean. Scientists call this a "whale fall."

... We can't open the brain and see by eye, but the cool thing we can do now is see through the MR machine, a technology that is much safer than earlier techniques such as X-ray imaging, said Yu. The first step in analyzing these images is to align their common anatomical structures, such as the central ...3.2 billion-year-old surprise: Earth had strong magnetic field
