...alyzing bacteria for more than a century, but it's amazing to me that we're still using a procedure that's effectively out of the Stone Age," says Miller.

It will allow us to betterunderstand the amazing ecosystem that exists in these vents andhow these organisms, which thrive under some of the harshestconditions on Earth, interact with each other.

We believe we have discovered a molecular basis for long-range blood cell migration. The sci...Researcher traces gene development in 'last common link'
...d." Fruit flies, mice, worms and apes share an amazing amount of genetic information with us humans and with each other. For instance, there is only one-tenth of one percent genetic variation between a human and a chimpanzee. A field of research has arisen to address what kinds of genetic change ove...Picky eaters rare among tropical insects
...tt Miller, NMNH insect taxonomist, remarked: It is amazing how few of the original assumptions have been tested in the last 20 years, despite a great number of general papers discussing the overall numbers. The work published this week in Nature estimates 3.7 to 5.9 million insects, much closer to estimates...A new weapon to disable bacteria discovered

In this manner neutrophils retain the Shigella long enough to mobilize other defenses that can destroy the bacteria. Indeed, neutrophils with inactivated elastase cannot contain Shigella in a vacuole, and...Ominous signs of cryptic marine invasions
