Why some penguin feathers never freeze
Oil and tiny pores prevent the feathers on some penguins from freezing. The discovery could inspire new ways to keep ice off of airplane wings.

Wet suits with hair?
The dense hair that keeps sea otters warm in frigid waters may inspire development of “furry” wet suits for scuba divers.

Faking out whales
A false “dinner bell” can safely distract hungry whales from stealing fish from commercial fishing lines, new research shows.

Water: Getting the salt out
A new water-cleansing technology passes electricity through a flow of salty water. This will generate a zone of fresh water that can then be collected.

Engineers consider liquid salt to generate power
A new type of power plant, a molten salt reactor, might provide electricity in a cleaner and safer way than current nuclear technology.

New e-skin feels heat, textures and more
Two new developments in electronic “skin” hold promise for making prosthetic devices that can provide a better sense of touch. One gets its great sensitivity from being modeled on the human fingertip.

Some 3-D printing can leave toxic taint
The ”ink” inside some 3-D printers can leave toxic traces. In tests, these chemicals harmed baby fish. But lighting could render the parts safer.

Taking attendance with eDNA
Environmental DNA, or eDNA, tells biologists what species are in an area — even when they’re out of sight.
