Modeling Jupiter and Saturn's possible origins

Posted: 05 Mar 2013 02:46 PM PST

New theoretical modeling provides clues to how the gas giant planets in our solar system -- Jupiter and Saturn -- might have formed and evolved.

Statistical physics offers a new way to look at climate

Posted: 05 Mar 2013 11:58 AM PST

New research suggests that statistical simulations rooted in basic physics could make for new climate models that are more useful and require less brute-force computing power. A new article shows how statistical simulations can be applied to fluid jets like the ones in Earth's atmosphere and oceans.

New evidence that comets could have seeded life on Earth

Posted: 05 Mar 2013 10:14 AM PST

Scientists have shown that complex molecules can form on icy dust in space, suggesting that comets may have brought these molecules to Earth and seeded the growth of more complex building blocks of life. The team zapped icy snowballs of carbon dioxide and hydrocarbons, producing complex molecules, such as dipeptides, that are capable of catalyzing the formation of more complex structures.

Analytical theory may bring improvements to lithium-ion batteries

Posted: 05 Mar 2013 10:14 AM PST

Researchers have shown theoretically how to control or eliminate the formation of "dendrites" that cause lithium-ion batteries to fail, an advance that if realized would improve safety and might enable the batteries to be charged within a matter of minutes instead of hours.

Jupiter's icy moon: Window into Europa's ocean lies right at the surface

Posted: 05 Mar 2013 10:12 AM PST

If you could lick the surface of Jupiter's icy moon Europa, you would actually be sampling a bit of the ocean beneath, according to astronomers. Astronomers have found the strongest evidence yet that salty water from the vast liquid ocean beneath Europa's frozen exterior actually makes its way to the surface.

New spectroscopy method could lead to better optical devices such as LEDs and solar cells

A new spectroscopy method helps distinguish the orientations of light-emitters in layered nanomaterials and other thin films. The method could lead to better thin-film optical devices like LEDs and solar cells.

Gravitational telescope creates space invader mirage

Posted: 05 Mar 2013 07:09 AM PST

The NASA/ESA Hubble Space Telescope is one of the most powerful available to astronomers, but sometimes it too needs a helping hand. This comes in the form of Einstein's general theory of relativity, which makes galaxy clusters act as natural lenses, amplifying the light coming from very distant galaxies.

Mental picture of others can be seen using fMRI, finds new study

Posted: 05 Mar 2013 06:10 AM PST

It is possible to tell who a person is thinking about by analyzing images of his or her brain. Our mental models of people produce unique patterns of brain activation, which can be detected using advanced imaging techniques according to a new study.

Mars rover Curiosity's recovery on track

Posted: 05 Mar 2013 05:40 AM PST

NASA's Mars rover Curiosity has transitioned from precautionary "safe mode" to active status on the path of recovery from a memory glitch last week. Resumption of full operations is anticipated by next week.

Synthetic fuels from natural gas and biomass? New Fischer-Tropsch catalyst invented

Posted: 05 Mar 2013 05:07 AM PST

Inspired by patents from the 1960s audio cassette recording industry, chemists now developed a new Fischer-Tropsch catalyst. It can be used for the making of synthetic fuels from natural gas and biomass.

Traceable nanoparticles may be the next weapon in cancer treatment

Posted: 05 Mar 2013 05:06 AM PST

Small particles loaded with medicine could be a future weapon for cancer treatment. A recently-published study shows how nanoparticles can be formed to efficiently carry cancer drugs to tumor cells. And because the particles can be seen in MRI images, they are traceable.
