Scientists and polar explorers brave the elements in support of CryoSat-2
04-19-2007 · European Space Agency (ESA)It is perhaps an unlikely combination – an international team of scientists stationed in Svalbard, Norway and two polar explorers crossing the North Pole on foot. Both teams, however, are currently part of a common effort to collect vital data on the ground and from the air in support of ESA's ice mission CryoSat-2.

- Virus used to create experimental HIV vaccines directly impairs the immune response
11-15-2007 · EurekAlert!
Leading efforts to create an HIV vaccine have hinged on the use of viruses as carriers for selected elements of the HIV virus. Recently, however, evidence has emerged that some of these so-called viral vector systems may undermine the immune system and should not be used for vaccine development. Now, a new study from scientists at the Wistar Institute provides strong support for the idea that some viral-vector vaccines may cause more harm than good.

- Antarctic marine explorers reveal first biological changes after collapse of polar ice shelves
02-25-2007 · EurekAlert!
Aboard the research icebreaker Polarstern some 52 Census of Marine Life (CoML)-affiliated scientists, led by experts from the Alfred Wegener Institute of Germany, have explored a near-pristine 10,000 sq km Antarctic seabed -- uncapped after several millennia when the Larsen A and B ice shelves disintegrated.

- Phoenix rising: Scientists resuscitate a 5 million-year-old retrovirus
10-30-2006 · EurekAlert!
A team of scientists has reconstructed the DNA sequence of a 5-million-year-old retrovirus and shown that it is able to produce infectious particles. The retrovirus -- named Phoenix -- is the ancestor of a large family of mobile DNA elements, some of which may play a role in cancer. The study is the first to generate an infectious retrovirus from a mobile element in the human genome. The findings are reported in Genome Research.

- Smithsonian scientists highlight environmental impacts of biofuels
01-03-2008 · EurekAlert!
Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. In the Jan. 4 issue of the journal Science, Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production. Corn, soy and sugarcane come up short. The authors urge governments to be far more selective about which biofuels they support, as not all are more environmentally friendly than fossil fuels.

- Targeting astrocytes slows disease progression in ALS
02-03-2008 · EurekAlert!
In what the researchers say could be promising news in the quest to find a therapy to slow the progression of amyotrophic lateral sclerosis, or Lou Gehrig's disease, scientists at the University of California, San Diego School of Medicine have shown that targeting neuronal support cells called astrocytes sharply slows disease progression in mice.

- First genome comparison of plankton species yields surprises underlying key ocean processes
04-30-2007 · EurekAlert!
An international team of scientists led by Scripps Institution of Oceanography at UC San Diego and the Department of Energy's Joint Genome Institute has peered into the genetic makeup of two species of phytoplankton, the tiny plants key in global photosynthesis and carbon cycling, and come away with surprising results about evolutionary engineering and new ideas about the role that a poorly understood chemical element may play in the world's oceans.

- Arizona State University scientist finds Martian ice is patchy and variable
05-02-2007 · EurekAlert!
For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.
