Search for Evidence of Life on Mars Heats Up

August 31, 2011 Leave a comment

Scientists are expressing confidence that questions about life on Mars, which have captured human imagination for centuries, finally may be answered, thanks in part to new life-detection tools up to 1,000 times more sensitive than previous instruments.

“The bottom line is that if life is out there, the high-tech tools of chemistry will find it sooner or later,” said Jeffrey Bada, Ph.D., co-organizer of a special two-day symposium on the Red Planet, which began here today during the 242nd National Meeting & Exposition of the American Chemical Society (ACS). “It certainly is starting to look like there may be something alive out there somewhere, with Mars being the most accessible place to search,” Bada added.

Discovery Sheds Light on Ecosystem of Young Galaxies

August 30, 2011 Leave a comment

A team of scientists, led by Michael Rauch from the Carnegie Observatories, has discovered a distant galaxy that may help elucidate two fundamental questions of galaxy formation: How galaxies take in matter and how they give off energetic radiation. Their work will be published in the Monthly Notices of the Royal Astronomical Society.

Interstellar Crashes Could Throw Out Habitable Planets

Our solar system, where planets have a range of sizes and move in near-circular paths, may be rather unusual, according to a German-British team led by Professor Pavel Kroupa of the University of Bonn. The astronomers, who publish their model in the journal Monthly Notices of the Royal Astronomical Society, find that forming planetary systems may be knocked around by crashes with nearby clumps of material, leading to systems where planets have highly inclined orbits and where the smaller (and potentially habitable) worlds are thrown out completely.

A Hint of Higgs: An Update from the LHC

August 16, 2011 1 comment

The CMS detector at the LHC weighs in at 14,000 metric tons.

The physics world was abuzz with some tantalizing news a couple of weeks ago. At a meeting of the European Physical Society in Grenoble, France, physicists—including some from Caltech—announced that the latest data from the Large Hadron Collider (LHC) might hint at the existence of the ever-elusive Higgs boson.
