Simulations lead to design of near-frictionless material

Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne ...

Marks on Martian dunes may be tracks of dry-ice sleds

(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.

'Dry water' could make a big splash commercially

An unusual substance known as "dry water," which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide, the major greenhouse gas that contributes to global warming, scientists reported today ...

El Nino could drive intense season for Amazon fires

The long-lasting effects of El Niño are projected to cause an intense fire season in the Amazon, according to the 2016 seasonal fire forecast from scientists at NASA and the University of California, Irvine.

Mars gullies likely contain 'no water', study says

Months after scientists announced "the strongest evidence yet" of liquid water on Mars, a study Monday said there was none at least in the valleys carved into numerous Red Planet slopes.
