"A team of researchers is the first to provide definitive proof that green algae eat bacteria. The finding, captured with electron microscope images, offers a glipse at how scienstists think early organisms acquired free-living chloroplasts"
Researchers have developed a new technique for quickly assessing the magnitude of large earthquakes, cutting down the time required in the case of the recent quake in Japan, for example, from about 20 minutes to just 2-3 minutes.

On this week’s Dialogue at the Wilson Center our guest is the director of the Wilson Center’s Science and Technology Innovation Program, David Rejeski. Additionally, David is a Visiting Scholar at the Environmental Law Institute and previously served at the White House Council on Environmental Quality and the Office of Science and Technology. He joins us to discuss the potential of 3-D printing and digital fabrication. Additional guests join us from the Fab Lab in Washington, D.C. for a hands-on look at the new technology.
What do you think? Is 3-D printing going to be a game changer?
We now know what caused the Irish potato famine. Scientists have pinpointed the pathogen by using plant samples collected in the mid-19th century. Weekends on All Things Considered host Jacki Lyden talks about it with the study's co-author, Sophien Kamoun of the Sainsbury Lab in the United Kingdom.
"Recently, significant progress has been made in understanding RNA silencing and how viruses counter this apparently ubiquitous antiviral defense. In addition, plants also induce hypersensitive and systemic acquired resistance responses, which together limit the virus to infected cells and impart resistance to the noninfected tissues."
