Cartilage made easy with novel hybrid printer Posted: 21 Nov 2012 06:01 PM PST The printing of three-dimensional tissue has taken a major step forward with the creation of a novel hybrid printer that simplifies the process of creating implantable cartilage.

Spacecraft monitoring Martian dust storm Posted: 21 Nov 2012 03:01 PM PST A Martian dust storm that NASA's Mars Reconnaissance Orbiter has been tracking since last week has also produced atmospheric changes detectable by rovers on Mars.

Gateway enzyme for chemicals from catnip to cancer drug discovered Posted: 21 Nov 2012 11:56 AM PST Scientists have discovered an enzyme used in nature to make powerful chemicals from catnip to a cancer drug, vinblastine. The discovery opens up the prospect of producing these chemicals cheaply and efficiently.

New structures self-assemble in synchronized dance Posted: 21 Nov 2012 11:56 AM PST With self-assembly guiding the steps and synchronization providing the rhythm, a new class of materials forms dynamic, moving structures in an intricate dance. Researchers have demonstrated tiny spheres that synchronize their movements as they self-assemble into a spinning microtube. Such in-motion structures, a blending of mathematics and materials science, could open a new class of technologies with applications in medicine, chemistry and engineering.

Dwarf planet Makemake lacks atmosphere: Distant frigid world reveals its secrets for first time Posted: 21 Nov 2012 11:55 AM PST Dwarf planet Makemake is about two thirds of the size of Pluto, and travels around the Sun in a distant path that lies beyond that of Pluto but closer to the Sun than Eris, the most massive known dwarf planet in the Solar System. Previous observations of chilly Makemake have shown it to be similar to its fellow dwarf planets, leading some astronomers to expect its atmosphere, if present, to be similar to that of Pluto. However, the new study now shows that, like Eris, Makemake is not surrounded by a significant atmosphere.
