Nea Kameni volcano movement captured by Envisat
Archived data from the Envisat satellite show that the volcanic island of Santorini has recently displayed signs of unrest. Even after the end of its mission, Envisat information continues to be exploited for the long-term monitoring of volcanoes. View More (2012-05-23)
Dawn reveals complexities of ancient asteroidal world
New findings from NASA's Dawn spacecraft lay the groundwork for the first geological overview of asteroid (4)Vesta and confirm the existence of not one but two giant impact basins in its southern hemisphere. View More (2012-05-11)
You're beautiful, Vesta
When UCLA's Christopher T. Russell looks at the images of the protoplanet Vesta produced by NASA's Dawn mission, he talks about beauty as much as he talks about science. View More (2012-05-11)
New Screening Technique from Scripps Research Institute Yields Elusive Compounds to Block Immune-Regulating Enzyme
Scientists at The Scripps Research Institute have found the first chemical compounds that act to block an enzyme that has been linked to inflammatory conditions such as asthma and arthritis, as well as some inflammation-promoted cancers. View More (2012-05-11)
TDRS-4 Mission Complete; Spacecraft Retired From Active Service

Report warns of rapid decline in US Earth observation capabilities; next-generation missions hindered by budget shortfalls, launch failures
A new National Research Council report says that budget shortfalls, cost-estimate growth, launch failures, and changes in mission design and scope have left U.S. earth observation systems in a more precarious position than they were five years ago. View More (2012-05-03)
Splatters of molten rock signal period of intense asteroid impacts on Earth
New research reveals that the Archean era - a formative time for early life from 3.8 billion years ago to 2.5 billion years ago - experienced far more major asteroid impacts than had been previously thought, with a few impacts perhaps even rivaling those that produced the largest craters on the Moon, according to a paper published online today in Nature.

Tiny 'spherules' reveal details about Earth's asteroid impacts
Researchers are learning details about asteroid impacts going back to the Earth's early history by using a new method for extracting precise information from tiny "spherules" embedded in layers of rock. View More (2012-04-26)
Medical 'lightsabers': Laser scalpels get ultrafast, ultra-accurate, and ultra-compact makeover
Whether surgeons slice with a traditional scalpel or cut away with a surgical laser, most medical operations end up removing some healthy tissue, along with the bad. View More (2012-04-24)
WSU astrobiologist proposes fleet of probes to seek life on Mars
A Washington State University astrobiologist is leading a group of 20 scientists in calling for a mission to Mars with "a strong and comprehensive life detection component." View More (2012-04-24)
EARTH: US Navy navigates a sea change in the Arctic
The idea that the Arctic is changing is not breaking news. Sea-ice extent has been declining by 12 percent per decade since 1979, and the ice is thinning too. Because of this, new shipping routes are becoming accessible during the summer months, and the Arctic is beginning to attract parties interested in resource exploration, scientific research and tourism.

Nanoscale magnetic media diagnostics by rippling spin waves
Memory devices based on magnetism are one of the core technologies of the computing industry, and engineers are working to develop new forms of magnetic memory that are faster, smaller, and more energy efficient than today's flash and SDRAM memory. View More (2012-04-04)
Mission critical: Species explorers propose steps to map biosphere
An ambitious goal to describe 10 million species in less than 50 years is achievable and necessary to sustain Earth's biodiversity, according to an international group of 39 scientists, scholars and engineers who provided a detailed plan, including measures to build public support, in the March 30 issue of the journal Systematics and Biodiversity.
