How atoms behave: Characteristics of microstructural avalanches
(PhysOrg.com) -- Investigating how atoms move and rearrange themselves is fundamental to our understanding of the behavior of materials, in particular efforts aimed at engineering materials with enhanced functionality. ...
Dry ice lake suggests Mars once had a 'Dust Bowl' (Update)
(PhysOrg.com) -- NASA's Mars Reconnaissance Orbiter has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet's axis varies. This process can affect the stability ...
More asteroids could have made life's ingredients

Hydrogel remembers its shape
(Phys.org)—A bit reminiscent of the Terminator T-1000, a new material created by Cornell researchers is so soft that it can flow like a liquid and then, strangely, return to its original shape.
Faith helped steer astronomy professor who made planet discovery
It was a Friday afternoon, Aug. 31 of last year, that Eric Agol, a 42-year-old associate professor of astronomy at the University of Washington, looked at his computer screen and saw something astounding.
Sulfurous signs of life
Any sulfurous molecules that astronomers spot on alien worlds might be a way to reveal whether or not those distant planets host life, researchers suggest.
Vitamin B3 might have been made in space, delivered to Earth by meteorites
Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin ...
What is creating gullies on Vesta?
(Phys.org)—In a preliminary analysis of images from NASA's Dawn mission, scientists have spotted intriguing gullies that sculpt the walls of geologically young craters on the giant asteroid Vesta. Led by ...
Liquid crystal turns water droplets into 'gemstones'
(Phys.org) —Liquid crystals are remarkable materials that combine the optical properties of crystalline solids with the flow properties of liquids, characteristics that come together to enable the displays ...
Out of thin Martian air
A wet Mars is just a memory, but where did the water go?
Nearby star cluster, long forgotten, now discovered to be useful in studies of Sun and search for planets like Earth
(Phys.org) -- A loose group of stars that was known for over 180 years but never before studied in detail has been revealed to be an important new tool in the quest to understand the evolution of stars like ...
Acidic Europa may eat away at chances for life
The ocean underneath the icy shell of Jupiter's moon Europa could be too acid to support life, due to compounds that may regularly migrate downward from its surface, researchers find.
Watery science 'jackpot' discovered by Curiosity
The Curiosity rover hit the science "jackpot" and has discovered widespread further evidence of multiple episodes of liquid water flowing over ancient Mars billions of years ago when the planet was warmer ...
Temperature extremes on Mars
"Mars ain't no kind of place to raise your kids; in fact it's cold as hell" sang Elton John in "Rocket Man", and although the song was released in 1972—four years before the first successful landing on Mar ...
