Satellites Record Weakening North Atlantic Current - SpaceDaily  Left:  Pathways associated with the transformation of warm subtropical waters into colder subpolar and polar waters in the northern North Atlantic. Along the subpolar gyre pathway the red to yellow transition indicates the cooling to Labrador Sea Water, which flows back to the subtropical gyre in the west as an intermediate depth current (yellow). More information Credit: ŠJack Cook, Woods Hole Oceanographic Institution More images at Top Story   A North Atlantic Ocean circulation system weakened considerably in the late 1990s, compared to the 1970s and 1980s, according to a NASA study. Sirpa Hakkinen, lead author and researcher at NASA's Goddard Space Flight Center, Greenbelt, Md. And co-author Peter Rhines, an oceanographer at the University of Washington, Seattle, believe slowing of this ocean current is an indication of dramatic changes in the North Atlantic Ocean climate. "We need another good five to 10 years to say something like that is happening. 
Student Research May Help Astronauts Burn Fuel On Mars - SpaceDaily  In Houston, the students conducted zero-gravity experiments using iodine as a catalyst to burn magnesium. Magnesium is a metal found on Mars that can be harvested for fuel-fossil fuels don't burn on Mars because of the planet's carbon dioxide (CO2) atmosphere, but metals do burn in a CO2 atmosphere. The idea for the students' experiments evolved from previous research done by Margaret Wooldridge, an associate professor in mechanical engineering and the team's adviser. Wooldridge's research showed that while magnesium is a promising fuel source, burning magnesium alone-without a catalyst such as iodine-has several challenges. Preliminary results from the student experiments showed that using iodine as a catalyst helped make the magnesium burn better, said Arianne Liepa, aerospace engineering undergrad and team member.

SuperWASP Begins The Search For Thousands Of New Planets - SpaceDaily  A consortium of astronomers is tomorrow (April 16th) celebrating the commissioning of the SuperWASP facility at the astronomical observatory on the island of La Palma in the Canary Islands, designed to detect thousands of planets outside of our own solar system. SuperWASP is the most ambitious project of its kind anywhere in the world. Its extremely wide field of view combined with its ability to measure brightness very precisely allows it to view large areas of the sky and accurately monitor the brightnesses of hundreds of thousands of stars.
