Go Ask ALICE: Learning About the Big Bang

Nearly 14 billion years ago, the universe began with a bang — a big one.

Scientists believe that the universe and everything within it began as an extremely hot, dense “soup” that eventually gave rise to galaxies, stars, planets and life and that continues to expand to this day.

Now scientists around the world are pushing back the frontiers of our understanding about the moment the universe was born using the Large Hadron Collider (LHC), a giant particle accelerator at CERN (the European Organization for Nuclear Research) near Geneva, Switzerland. (more…)

Facebook Founder Mark Zuckerberg Named ‘Person of the Year’ by Time

Mark Zuckerberg, founder of Facebook Inc., was named Time magazine’s “Person of the Year” today for “creating a new system of exchanging information” and “changing how we all live our lives.”

Zuckerberg, 26, began the world’s largest social-networking site in 2004. The service, with more than 500 million users, has helped people connect with each other and changed definitions of privacy, Time Managing Editor Richard Stengel said in a letter on the magazine’s website. (more…)

What “Pine” Cones Reveal About the Evolution of Flowers

*Research genetically traces flowers to a single common ancestor*

From southern Africa’s pineapple lily to Western Australia’s swamp bottlebrush, flowering plants are everywhere. Also called angiosperms, they make up 90 percent of all land-based, plant life.

New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming similar to a water lily may have started it all. (more…)

Marijuana Use is Rising; Ecstasy Use is Beginning to Rise; and Alcohol Use is Declining Among U.S. Teens

ANN ARBOR, Mich.— Several important findings come out of this year’s Monitoring the Future study, the 36th annual, national survey of American teens in a series that launched in 1975.

• Marijuana use, which had been rising among teens for the past two years, continues to rise again this year—a sharp contrast to the considerable decline of the preceding decade.

• Ecstasy use—which fell out of favor in the early 2000s as concerns about its dangers grew—appears to be making a comeback this year, following a considerable recent decline in the belief that its use is dangerous.

• Alcohol use—and, specifically, occasions of heavy drinking—continues its long-term decline among teens into 2010, reaching historically low levels. (more…)

Cassini Spots Potential Ice Volcano on Saturn Moon

PASADENA, Calif. — NASA’s Cassini spacecraft has found possible ice volcanoes on Saturn’s moon Titan that are similar in shape to those on Earth that spew molten rock.

Topography and surface composition data have enabled scientists to make the best case yet in the outer solar system for an Earth-like volcano landform that erupts in ice. The results were presented on December 14 at the American Geophysical Union meeting in San Francisco. (more…)

High-Tech Software and Unmanned Planes Allow Scientists to Keep Tabs on Arctic Seals

A novel project using cameras mounted on unmanned aircraft flying over the Arctic is serving double duty by assessing the characteristics of declining sea ice and using the same aerial photos to pinpoint seals that have hauled up on ice floes.

The project is the first to use aircraft to monitor ice and seals in remote areas without putting pilots and observers at risk, said Elizabeth Weatherhead of the University of Colorado at Boulder, who is leading the study team. Weatherhead is a senior scientist at the Cooperative Institute for Research in Environmental Sciences, a joint venture of CU-Boulder and the National Oceanic and Atmospheric Administration. (more…)

‘Music and Caroling an Important Part of Holiday Celebrations’

During the holidays, no matter how you celebrate or what your beliefs, music is almost always an important part of the celebration, according to Thomas Riis, a musicologist and director of the American Music Research Center in the University of Colorado at Boulder’s College of Music.

“Singing brings people together and is a natural and comfortable community activity,” Riis said. (more…)
