In honor of the Earth Day celebration, NASA scientists unveiled the first consistent and continuous global measurements of Earth’s “metabolism.” Data from the Terra and Aqua satellites are helping scientists frequently update maps of the rate at which plant life on Earth is absorbing carbon out of the atmosphere.

Combining space-based measurements of a range of plant properties collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) with a suite of other satellite and su

Karaoke may never be the same, thanks to research being presented in Nashville detailing the latest findings in efforts to create a computerized system that makes average singers sound like professionals.

“Our ultimate goal is to have a computer system that will transform a poor singing voice into a great singing voice,” said Mark J.T. Smith, a professor and head of Purdue University’s School of Electrical and Computer Engineering.

To that end Smith, a former faculty member at

It might be 500,000 years or five years, but the Central Valley of Costa Rica will definitely experience major volcanic activity again, according to Phillip B. Gans, professor of geology at the University of California, Santa Barbara. He presented a study of volcanic rocks of Costa Rica in his recent talk at the annual meeting of the Geological Society of America.

“The Costa Ricans were not around for the last big one, but it’s inevitable,” said Gans. “Another pyroclastic flow like the

Jefferson Lab physicists will soon begin their own version of reuse — not with run-of-the-mill materials, but with radiofrequency energy and the high-energy electrons that they energize.

Newspaper, glass and aluminum recycling has become commonplace for most households and businesses. Jefferson Lab physicists will soon begin their own version of reuse — not with run-of-the-mill materials, but with radiofrequency energy and the high-energy electrons that they energize.

Laying water mains has always been a time-consuming job. Each section must be laid, joints welded, the interior checked for heat damage, and any damage repaired. Then the whole thing has to be encased in concrete if the ground is uneven. Now EUREKA project DRIVE-LOCK is about to make the process quicker and cheaper.

The French and Swiss partners in the DRIVE-LOCK project have developed a new conical interlocking system that joins steel water pipes together quickly and combines the strength o

Like the fury of a raging sea, this anniversary image from the NASA/ESA Hubble Space Telescope shows a bubbly ocean of glowing hydrogen, oxygen, and sulphur gas in the extremely massive and luminous molecular nebula Messier 17.

This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation. The release of this image commemorates the thirte
