Catherine Russell is a lady born to music. Her father, Luis Russell (1902-63), was Louis Armstrong's orchestra leader beginning in the mid-1930s. Her mother, Carline Ray, is a bassist, singer, great all-around musician and a member of the International Sweethearts of Rhythm, the 1940s all-woman band that swung as hard as the men. "This Daughter of Jazz Is One Cool Cat," reads the headline of Nat Hentoff's profile for The Wall Street Journal.

The newly reunited power-pop pioneers in The dB's make their first appearance on Mountain Stage, recorded live in Charleston, W.V. Often described as the band that filled the gap between Big Star and R.E.M. in the early '80s, The dB's helped change the course of guitar-driven power-pop for years to come.
NASA says it has found proof that water shaped the rocks on the left, in a photograph taken by the Mars rover Curiosity (left). For comparison, the agency released an image of rocks from the Earth (right).
Pathfinder, 1997: The first mission to land a rover on Mars, Pathfinder touched down in Ares Vallis, an ancient flood plain in the planet's northern hemisphere. Among the 2.3 billion bits of data sent back by the lander and its rover, Sojourner, were 15 chemical analyses of rocks and soil, which suggested Mars had once had liquid water and a thicker atmosphere.
Spirit, 2010: When NASA's Spirit rover got stuck in Martian sand, it proved to be a lucky break: The spinning wheel churned up soil that provided evidence of rocks formed in the presence of water.
Opportunity, 2004: Opportunity discovered tiny mineral spheres — nicknamed blueberries — poking out of rocks that were likely formed by water. Researchers using Opportunity's science instruments identified them as concretions rich in the mineral hematite, deposited by water saturating the bedrock.
Curiosity 2012: A wider view of the outcrop of a former streambed shows bedrock that scientists believe was likely exposed by meteorites striking the surface of Mars.

NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.
"You had water transporting these gravels to the downslope of the fan," NASA researchers say. The gravel then formed into a conglomerate rock, which was in turn likely covered before being exposed again.
