Photo from NASA Mars orbiter shows wind's handiwork

(PhysOrg.com) -- Some images of stark Martian landscapes provide visual appeal beyond their science value, including a recent scene of wind-sculpted features from the High Resolution Imaging Science Experiment (HiRISE) camera ...

Ripples in space key to understanding cosmic rays

In a new study researchers at the Swedish Institute of Space Physics have used measurements from NASA's MMS (Magnetospheric MultiScale) satellites to reveal that there are ripples, or surface waves, moving along the surface ...

Curiosity rover's sand-dune studies yield surprise

Some of the wind-sculpted sand ripples on Mars are a type not seen on Earth, and their relationship to the thin Martian atmosphere today provides new clues about the atmosphere's history.

Nanobelts support manipulation of light

(PhysOrg.com) -- They look like 2-by-4s, but the materials being created in a Rice University lab are more suited to construction with light.

Ripples in the cosmic background

(PhysOrg.com) -- The universe was created 13.73 billion years ago in a blaze of light -- the big bang. We also think that, about 380,000 years later, after matter (mostly hydrogen atoms) had cooled enough for neutral atoms ...

Rethinking surface tension

(Phys.org) —If you've ever watched a drop of water form into a bead or a water strider scoot across a pond, you are familiar with a property of liquids called surface tension.

Scientists explore the physics of bumpy roads

sand or gravel or snow -- develops ripples that make driving a very shaky experience. A team of physicists from Canada, France and the United Kingdom have recreated this "washboard" phenomenon in the lab with surprising results: ...

How nature's patterns form

When people on airplanes ask Alan Newell what he works on, he tells them "flower arrangements."
