Submission + - Oxygen-rich atmosphere discovered on Rhea (space.com)

Submitted by Randyll
Randyll writes: During its Saturn flyby in March the Cassini space probe detected an oxygen-rich atmosphere on Rhea, Saturn's second-largest moon. While 100 times thinner than the atmospheres of Europa or Ganymede, the atmosphere contains a surprising amount of carbon dioxide. There is an explanation for the oxygen, while the origin of the carbon dioxide is a mystery. A few of the possible explanations are that Rhea has carbon-rich organic molecules or that the gas is seeping from Rhea's interior, however researchers have been unable to determine the exact source for the gas.

Submission + - Pirate Bay trio lose appeal (pcpro.co.uk)

nk497 writes: Three of the founders of The Pirate Bay have lost an appeal against their conviction last year of helping to share copyright material. It wasn't a total waste of time, however. Three of the foursome have had their one-year jail sentences cut to between four and ten months. (The fourth was too ill to appear in court, and will appeal separately.) The foursome also had their fine bumped from 32 million kronor to 46 million kronor.

3-D Printer Creates Buildings From Dust and Glue 139

Posted by timothy from the one-layer-at-a-time dept.
An anonymous reader writes "D-Shape, an innovative new 3-D printer, builds solid structures like sculptures, furniture, even buildings from the ground up. The device relies on sand and magnesium glue to actually build structures layer by layer from solid stone. The designer, Enrico Dini, is even talking with various organizations about making the printer compatible with moon dust, paving the way for an instant moonbase!"

Submission + - Fermilab Detects "Doubly Strange" Particle (fnal.gov)

Recently Fermilab announced discovery of the Omega-sub-b baryon, a 'doubly-strange' particle http://www.fnal.gov/pub/presspass/press_releases/CDF-Omega-observation.html . This baryon, containing two strange quarks and one bottom quark, has six times the mass of a proton. "The Omega-sub-b is the latest entry in the "periodic table of baryons." Baryons are particles formed of three quarks, the most common examples being the proton and neutron. ... The observation of this "doubly strange" particle, predicted by the Standard Model, is significant because it strengthens physicists' confidence in their understanding of how quarks form matter. In addition, it conflicts with a 2008 result announced by CDF's sister experiment, DZero. In August 2008, the DZero experiment announced its own observation of the Omega-sub-b based on a smaller sample of Tevatron data. This result contradicted some predictions of the Standard Model, suggesting a 'new physics'. The new result leads to the possibility that the prior results are not accurate." To observe this particle, analysis of DHC data required pouring through a trillion (10^15) observations, finding only 16 instances of the predicted outcome."

It isn't easy being the parent of a six-year-old. However, it's a pretty small price to pay for having somebody around the house who understands computers.
