The startling new insight into the workings of one of the most important and environmentally friendly weapons in the human arsenal against insect pests has significant implications not only for the control of insects in agriculture, forestry and human health, but ...Ocean microbe census discovers diverse world of rare bacteria
A startling revelation about the number of different kinds of bacteria in the deep-sea raises fundamental new questions about microbial life and evolution in the oceans.

For example, within days of its launch in 2002, ESA's environmental satellite Envisat captured the disintegration of the Larsen-B ice shelf in Antarctica, surprising scientists because of the rapid rate at which the shelf broke apart. ...New research reveals unexpected post-mating gene expression in model lab insect
... and discovered the presence in mated females of a startling 539 genes whose activity changes after mating. "One novel feature of this research was Paul's decision to look at what happens over time," said Bender. "That's how we found out that the activity hits a peak six hours after mating. This indicates qu...News tips from The Journal of Neuroscience

Nearly half of that, $18.1 billion, was for babies with a diagnosis of prematurity or low birth weight. Today 1,300 babies in the U.S. will be born prematurely.
