Could life exist on Mars?
The question of whether life is or ever existed on Mars remains unknown. However, scientists have shown that bacteria isolated from the Arctic could survive under Martian conditions.
Dust Devils Scour Surface of Mars
astroengine writes "Dust devils are a well-known atmospheric phenomena on Mars, and as these new HiRISE observations show, the devilish vorticies can carve beautiful patterns in the Martian dust. What's more — in side-by-side comparisons of observations of the same Mars region years apart — it appears that the active Mars atmosphere acts like an Etch A Sketch, rubbing out the dust devils' tracks, only for the dust devils to make brand new tracks years later."
Ancient Flood Channels Cut Deep Into Mars
astroengine writes "Relatively recently, water blasted out from an underground aquifer on Mars, carving out deep flood channels in the surface that were later buried by lava flows, radar images complied from NASA's Mars Reconnaissance Orbiter probe shows. The channels are at least twice as deep as previous estimates for Marte Vallis, an expanse of plains just north of the Martian equator that is the youngest volcanic region on the planet. "We see similar channels elsewhere on Mars and they are not filled with lava so it's important to be able to compare different channel systems, and also similar systems on Earth, to give us clues about how they formed," lead researcher Gareth Morgan, with the Smithsonian Institution in Washington DC, told Discovery News."

Martian language lessons on offer at Pompidou Centre, Paris

Backed Or Whacked: Revenge Of The Dumb Watch
Editor’s note: Ross Rubin is principal analyst at Reticle Research and blogs at Techspressive. Each column will look at crowdfunded products that have either met or missed their funding goals. Last year, Kickstarter launched a bumper crop of smart watches that connect via Bluetooth to your smartphone. The field was led by the record-setting Pebble, but also included products such as Cookoo, the MetaWatch Strata, and Martian, all of which have shipped by now. Recently, though, a number of timepieces have surfaced that bring us back to basics when it comes to telling time.
