Life-Detector Test A fuel cell could detect the presence of life on other worlds by measuring the redox reactions that happen in the metabolic process. Technology Review
If life exists on other planets, it won’t necessarily have the same carbon-based metabolism we do, so detecting its presence will require some sophistication. Now, a group of Argentinian researchers say they’ve come up with a method that will work to detect any form of life.
Ximena Abreyava and colleagues suggest using a microbial fuel c…

DNA-testing Martian soil could lead us to life on another planet
Someday, microfluidics chips like this one might suss out life on Mars. The chip, developed by Gary Ruvkun, a professor of genetics at Harvard University, would ride along on a soil-collecting rover and search for microscopic life within Martian dust.
It will use a combination of buffer solution, detergent and high-frequency sound waves to disrupt the cells, causing any minuscule Martians to release their genetic material. Chemicals in the…

Until recently, radio astronomers have concentrated almost exclusively on the high-energy radiation streaming in towards Earth from exotic stellar bodies like pulsars, quasars, and super-massive black holes. But now, a new European observatory called the Low Frequency Array (LOFAR) has begun releasing data on the low-energy radiation that permeates the Universe.
While seemingly less sexy than high-energy research, low-energy radiation actually allows scientists to look even deeper into the past, to with…

Like GPS for marstronauts
It will probably take another decade to perfect the sophisticated rocket and life-support technology needed to put a human on Mars. But once we’re there, NASA may use centuries-old technology to keep us from getting lost during a stroll.
