Craters on the moon: Pre-existing mineralogy may survive lunar impacts Posted: 02 Apr 2013 12:01 PM PDT Large impacts on the Moon can form wide craters and turn surface rock liquid. Geophysicists once assumed that liquid rock would be homogenous when it cooled. Now researchers have found evidence that pre-existing mineralogy can survive impact melt.

Seismic hazards: Seismic simulation code speeds up Posted: 02 Apr 2013 11:45 AM PDT Scientists have developed a highly scalable computer code that promises to dramatically cut both research times and energy costs in simulating seismic hazards throughout California and elsewhere.

New insights on how spiral galaxies get their arms Posted: 02 Apr 2013 09:48 AM PDT Spiral galaxies are some of the most beautiful and photogenic residents of the universe. Our own Milky Way is a spiral. Our solar system and Earth reside somewhere near one of its filamentous arms. And nearly 70 percent of the galaxies closest to the Milky Way are spirals. But despite their common shape, how galaxies like ours get and maintain their characteristic arms has proved to be an enduring puzzle in astrophysics.

3-D scaffolds a new tool to fight cancer Posted: 02 Apr 2013 09:48 AM PDT Porous polymer scaffolds fabricated to support the growth of biological tissue for implantation may hold the potential to greatly accelerate the development of cancer therapeutics. Researchers report that three-dimensional scaffolds used to culture Ewing's sarcoma cells were effective at mimicking the environment in which such tumors develop.

Fighting listeria and other food-borne illnesses with nanobiotechnology Posted: 02 Apr 2013 09:43 AM PDT Engineering researchers have developed a new method to kill deadly pathogenic bacteria, including listeria, in food handling and packaging. This innovation represents an alternative to the use of antibiotics or chemical decontamination in food supply systems.

Hubble sees J 900 masquerading as a double star Posted: 02 Apr 2013 07:19 AM PDT A new image from the Hubble Space Telescope shows Jonckheere 900 or J 900, a planetary nebula -- glowing shells of ionized gas pushed out by a dying star. Discovered in the early 1900s by astronomer Robert Jonckheere, the dusty nebula is small but fairly bright, with a relatively evenly spread central region surrounded by soft wispy edges.

New instrument will quickly detect botulinum, ricin, other biothreat agents Posted: 02 Apr 2013 07:11 AM PDT Researchers are developing a medical instrument that will be able to quickly detect a suite of biothreat agents, including anthrax, ricin, botulinum, shiga and SEB toxin. The device, once developed, approved by the U.S. Food and Drug Administration and commercialized, would most likely be used in emergency rooms in the event of a bioterrorism incident.

A longer life for lithium-sulfur batteries Posted: 02 Apr 2013 06:12 AM PDT Electric cars have still got it tough in the German marketplace. They are too expensive and their range is too short. This is an opportune time for a breakthrough in efficient and low-cost lithium-sulfur batteries.

New clues in the search to rediscover the mysterious Maya Blue formula Posted: 02 Apr 2013 06:11 AM PDT The recipe and process for preparing Maya Blue, a highly-resistant pigment used for centuries in Mesoamerica, were lost. We know that the ingredients are a plant dye, indigo, and a type of clay known as palygorskite, but scientists do not know how they were 'cooked' and combined together. Now, a team of chemists has come up with a new hypothesis about how it was prepared.

Plastic film is the future of 3-D on-the-go Posted: 02 Apr 2013 06:07 AM PDT Ditch the 3-D glasses. Thanks to a simple plastic filter, mobile device users can now view unprecedented, distortion-free, brilliant 3-D content with the naked eye. This latest innovation from TP and IMRE is the first ever glasses-free 3-D accessory that can display content in both portrait and landscape mode, and measures less than 0.1 mm in thickness.Mobile device users will soon be able to view brilliant 3-D content with the naked eye with a nano-engineered screen protector that turns ordinary mobile screens into 3-D displays. The unique plastic film can also potentially be used as next generation security tokens employed by banks and corporations.
