Naming an atomic heavyweight
More than a decade after its debut in a German lab, element 112 is officially named copernicium.

Superheavy element 117 makes debut
An international team of researchers fill a gap in the periodic table, and lay another stepping stone along the path to the “island of stability.”

A new source of dioxins: Clean hands
Manufacturers have been adding the germ fighter triclosan to soaps, hand washes, and a range of other products for years. But here’s a dirty little secret: Once it washes down the drain, that triclosan can spawn dioxins.

Nobel Prize in chemistry commends finding and use of green fluorescent protein
One researcher is awarded for discovering the protein that helps jellyfish glow and two for making the protein into a crucial tool for biologists.

Chinese would turn cigarette butts into steel’s guardian
People smoke a lot of cigarettes, which leads to a lot of trash. Tom Novotny has done the math: An estimated 5.6 trillion butts each year end up littering the global environment. But Chinese researchers have a solution: recycling. Their new data indicate that an aqueous extract of stinky butts makes a great corrosion inhibitor for steel.

Cap or cork, it’s the wine that matters most
Comparative study finds that screw tops can perform just as well in regulating the aging process.

Rural ozone can be fed by feed (as in silage)
Livestock operations take a lot of flak for polluting. Researchers are now linking ozone to livestock, at least in one of the nation's most agriculturally intense centers. And here the pollution source is not what comes out the back end of an animal but what’s destined to go in the front.

Tiny molecules walk the track
Researchers design synthetic “walking” molecules that may one day haul cargo in artificial micromachines.

The skinny on indoor ozone
Indoor concentrations of ozone tend to be far lower than those outside, largely because much gets destroyed as molecules of the respiratory irritant collide with surfaces and undergo transformative chemical reactions. New research identifies a hitherto ignored surface that apparently plays a major role in quashing indoor ozone: It’s human skin. And while removing ozone from indoor air should be good, what takes its place may not be, data indicate.

New material sops up radioactive cesium
Isotope catcher could safely store waste from power plants.
