NASA Voyager 1 encounters new region in deep space Posted: 03 Dec 2012 12:45 PM PST NASA's Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space.

Multitasking plasmonic nanobubbles kill diseased cells, modify others Posted: 03 Dec 2012 11:59 AM PST Researchers have found a way to kill some diseased cells and treat others in the same sample at the same time. The process activated by a pulse of laser light leaves neighboring healthy cells untouched.

Happy face tattoo does serious work Posted: 03 Dec 2012 10:11 AM PST A medical sensor that attaches to the skin like a temporary tattoo could make it easier for doctors to detect metabolic problems in patients and for coaches to fine-tune athletes' training routines. And the entire sensor comes in a thin, flexible package shaped like a smiley face.

Pygmy mole crickets don't just walk on water, they jump on it Posted: 03 Dec 2012 09:16 AM PST Pygmy mole crickets are known to be prodigious jumpers on land. Now, researchers have found that the tiny insects have found an ingenious method to jump from the water, too. Their secret is a series of spring-loaded, oar-like paddles on their back legs.

Complex chemistry within the Martian soil: No definitive detection of organics yet Posted: 03 Dec 2012 09:07 AM PST NASA's Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity's arm delivered to an analytical laboratory inside the rover. Researchers reported that they have no definitive detection of Martian organics at this point, but they will keep looking in the diverse environments of Gale Crater.

World's smallest wrench puts new twist on microscopic manipulation; Harnesses laser light's ability to gently push and pull Posted: 03 Dec 2012 06:34 AM PST Harnessing laser light's ability to gently push and pull microscopic particles, researchers have created the fiber-optic equivalent of the world's smallest wrench. This virtual tool can precisely twist and turn the tiniest of particles, from living cells and DNA to microscopic motors and dynamos used in biological and physical research.

Have Venusian volcanoes been caught in the act? Posted: 03 Dec 2012 05:18 AM PST Six years of observations by the European Space Agency's Venus Express have shown large changes in the sulfur dioxide content of the planet's atmosphere, and one intriguing possible explanation is volcanic eruptions. The thick atmosphere of Venus contains over a million times as much sulfur dioxide as Earth's, where almost all of the pungent, toxic gas is generated by volcanic activity. Most of the sulfur dioxide on Venus is hidden below the planet's dense upper cloud deck, because the gas is readily destroyed by sunlight. That means any sulfur dioxide detected in Venus' upper atmosphere above the cloud deck must have been recently supplied from below.

Dichlorophenol-containing pesticides linked to food allergies, study finds; Chemical also used to chlorinate tap water Posted: 03 Dec 2012 05:16 AM PST A new study finds that high levels of dichlorophenols, a chemical used in pesticides and to chlorinate water, when found in the human body, are associated with food allergies.

Taking the buzz out of office lights: Flicker-free, shatterproof alternative for large-scale lighting Posted: 03 Dec 2012 05:16 AM PST Say goodbye to that annoying buzz created by overhead fluorescent light bulbs in your office. Scientists have developed a flicker-free, shatterproof alternative for large-scale lighting. The research using FIPEL technology soon will have home applications as well.
