PASADENA, Calif. – A NASA-led science team has created an accurate, high-resolution map of the height of Earth’s forests. The map will help scientists better understand the role forests play in climate change and how their heights influence wildlife habitats within them, while also helping them quantify the carbon stored in Earth’s vegetation.

Scientists from NASA’s Jet Propulsion Laboratory, Pasadena, Calif.; the University of Maryland, College Park; and Woods Hole Research Center, Falmouth, Mass., created the map using 2.5 million carefully screened, globally distributed laser pulse measurements from space. The light detection and ranging (lidar) data were collected in 2005 by the Geoscience Laser Altimeter System instrument on NASA’s Ice, Cloud and land Elevation Satellite (ICESat). (more…)

Predators Hunt for A Balanced Diet

Predators select their prey in order to eat a nutritionally balanced diet and give themselves the best chance of producing healthy offspring.

A University of Exeter and Oxford-led study published in Proceedings of the Royal Society B shows for the first time that predatory animals choose their food on the basis of its nutritional value, rather than just overall calorie content.

An international team of scientists from the Universities of Exeter and Oxford in the UK, University of Sydney (Australia), Aarhus University (Denmark) and Massey University (New Zealand) based their research on the ground beetle, Anchomenus dorsalis, a well-known garden insect that feasts on slugs, aphids, moths, beetle larvae and ants.

A three-year series of research flights from the Arctic to the Antarctic has successfully produced an unprecedented portrait of greenhouse gases and particles in the atmosphere.

The far-reaching field project, known as HIPPO, ends this week, and has enabled researchers to generate the first detailed mapping of the global distribution of gases and particles that affect Earth’s climate. (more…)

NEW YORK CITY – Microsoft CEO Steve Ballmer inspired them to be great, economist Jeffrey Sachs gave them the homework assignment of saving the world, and Foursquare founder and CEO Dennis Crowley showed them how tangibly close they are to success.

Students representing 70 countries and regions descended on New York City over the weekend to participate in the Imagine Cup 2011 Worldwide Finals, which challenges students from across the globe to use technology to solve world problems like feeding the hungry, fighting disease, and creating new forms of energy. Finalists in the competition’s nine categories were announced on Sunday and the overall winners will be announced on Wednesday. (more…)

New Zealand Mountain Named in Honor of Yale Astronomer

Acclaimed by her peers in the United States as “possibly the greatest woman scientist of the 20th century” and known in her native New Zealand as a “world leader in modern cosmology and one of the most creative and significant theoreticians in modern astronomy,” the late Yale astronomer Beatrice Tinsley has certainly earned a place in the annals of history.

Now she’s earned a place in the World Atlas as well. (more…)

The pristine state of unpolluted waterways may be their downfall, according to research results published in a paper this week in the journal Geophysical Research Letters.

A species of freshwater algae that lives in streams and rivers, called Didymo for Didymosphenia geminata, is able to colonize and dominate the bottoms of some of the world’s cleanest waterways–precisely because they are so clear. (more…)

Free-Floating Planets May be More Common Than Stars

PASADENA, Calif. — Astronomers, including a NASA-funded team member, have discovered a new class of Jupiter-sized planets floating alone in the dark of space, away from the light of a star. The team believes these lone worlds were probably ejected from developing planetary systems.

The discovery is based on a joint Japan-New Zealand survey that scanned the center of the Milky Way galaxy during 2006 and 2007, revealing evidence for up to 10 free-floating planets roughly the mass of Jupiter. The isolated orbs, also known as orphan planets, are difficult to spot, and had gone undetected until now. The newfound planets are located at an average approximate distance of 10,000 to 20,000 light-years from Earth. (more…)
