Astrophysics

"Shining new light on dark energy with galaxy clusters." Scientists' murky understanding of dark energy may have just gotten a little clearer, thanks to recent work by a team of researchers that includes astrophysicist Neelima Sehgal of the Kavli Institute for Particle Astrophysics and Cosmology at SLAC. The team used observations from the Atacama Cosmology Telescope, or ACT, in the Chilean Andes to more narrowly define the properties of dark energy.

Life Science

"Q&A: 'Science' journal official talks arsenic-based life." A recent announcement of the discovery of arsenic-based life on Earth was preceded by intense media speculation about possible implications for the search for extraterrestrial life. Now the journal Science is looking to keep the discussion grounded in a more Earthly reality. Live Science (via Jeremy Hsu and Nature News&Comment).
