Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system. Scientists at the University of Chicago and NASA Ames Research Center came to this conclusion after linking computer simulations to laboratory experiments.

Fred Ciesla, assistant professor in geophysical sciences at UChicago, simulated the dynamics of the solar nebula, the cloud of gas and dust from which the sun and the planets formed. Although every dust particle within the nebula behaved differently, they all experienced the conditions needed for organics to form over a simulated million-year period. (more…)

The Yale Center for British Art is partnering with the Google Art Project to share the museum’s renowned collections with viewers around the world. The collaboration is part of a major global expansion of the pioneering Art Project, which now consists of 151 partners in 40 countries.

The Yale Center for British Art — which houses the largest collection of British art outside the United Kingdom — is one of only six university museums in the world to collaborate with Google. It is one of only 29 institutions in the United States and is the only museum in Connecticut to participate. (more…)

Berkeley Lab scientists are the leaders of BOSS, the Baryon Oscillation Spectroscopic Survey. They and their colleagues in the third Sloan Digital Sky Survey have announced the most precise measurements ever made of the era when dark energy turned on.

Some six billion light years distant, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the matter it contained, the universe had been expanding ever more slowly. Then, as matter spread out and its density decreased, dark energy took over and expansion began to accelerate.

Today BOSS, the Baryon Oscillation Spectroscopic Survey, the largest component of the third Sloan Digital Sky Survey (SDSS-III), announced the most accurate measurement yet of the distance scale of the universe during the era when dark energy turned on. (more…)

Android Captures Majority Share of U.S. Smartphone Market

RESTON, VA, April 3, 2012 – comScore, Inc., a leader in measuring the digital world, today released data from the comScore MobiLens service, reporting key trends in the U.S. mobile phone industry during the three month average period ending February 2012. The study surveyed more than 30,000 U.S. mobile subscribers and found Samsung to be the top handset manufacturer overall with 25.6 percent market share. Google Android continued to grow its share in the U.S. smartphone market, crossing the 50-percent threshold in February to capture a majority share for the first time in its history.

OEM Market Share

For the three-month average period ending in February, 234 million Americans age 13 and older used mobile devices. Device manufacturer Samsung ranked as the top OEM with 25.6 percent of U.S. mobile subscribers, followed by LG with 19.4 percent share. Apple captured the #3 ranking in February with 13.5 percent of mobile subscribers (up 2.3 percentage points), followed by Motorola at 12.8 percent. HTC moved into the #5 position in February at 6.3 percent (up 0.4 percentage points). (more…)

Imagine being able to use electricity to power your car — even if it’s not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity.

Today, electrical energy generated by various methods is still difficult to store efficiently. Chemical batteries, hydraulic pumping and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. (more…)
