Dazzling images of life on a cellular level now greet travelers flying into the U.S. capital, as Tina Hesman Saey reported in “Microscapes take off at D.C.’s Dulles airport” (SN: 7/26/14, p. 28). The exhibit, called “Life: Magnified,” offers viewers a glimpse of cells, microorganisms and other microscopic details at larger-than-life size.

In 2008, it was set to become the world’s largest demonstration of just how cleanly coal could be burned to generate electricity. The revamping of an aging power plant in Germany, Jänschwalde was to become a paragon of a technology that can slash up to 90 percent of the carbon dioxide emitted by fossil fuel–burning power plants — the single...

Robots that hunt down and exterminate jellyfish: Good or bad idea? Discuss.
A 2013 video from robotics designers at the Korea Advanced Institute of Science and Technology shows three jelly-killer prototypes gliding as a metallic fleet over gently rippling water. An underwater video demonstrates the cunning plan. Pale jellyfish bells drift into view, and a...
Odd-ball quasars may be closer than they seem — The odd-ball heavenly objects called quasars may be much closer to the earth’s own Milky Way galaxy than astronomers have thought. ... They have been regarded as the brightest and most distant objects known. However, they may not be so distant after all. Dr. James Terrell … believes quasars could be within two billion billion miles of earth...
