Satellite Observations Help Assess Future Earthquake Risk in Haiti
February 03, 2010 — Viginia Key — Scientists at the University of Miami have analyzed images based on Synthetic Aperture Radar (SAR) observations taken before and just after Haiti's earthquake, on January 12. The images reveal surprising new details. The images were obtained using data from Japan's ALOS satellite and made available to the scientific community through the efforts of GEO, the Group of Earth Observation, an umbrella group of many countries that promotes the exchange of satellite data to efficiently observe our planet, and the European Space Agency (ESA).

Herschel readies itself for the Orion Nebula
Herschel readies itself for the Orion Nebula , showed that it was performing beyond its design specification. However, by 3 August 2009, something was clearly wrong and the instrument team and ESA had to decide what to do. Herschel is stationed 1.5 million kilometres from Earth, directly away from the Sun, and way out of the reach of astronauts.

Spectacular Mars images reveal evidence of ancient lakes
Spectacular Mars images reveal evidence of ancient lakes
Spectacular satellite images suggest that Mars was warm enough to sustain lakes 3 billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in Geology . The research, by a team from Imperial College London and UCL, suggests that during the Hesperian Epoch, approximately 3 billion years ago, Mars had lakes made of melted ice, each around 20km wide, along parts of the equator.

Scientists Use Light to Map Neurons’ Effects on One Another
Cambridge, Mass. December 17, 2009 - Scientists at Harvard University have used light and genetic trickery to trace out neurons' ability to excite or inhibit one another, literally shedding new light on the question of how neurons interact with one another in live animals. The work is described in the current issue of the journal Nature Methods.

Mastery of physical goals lessens disease-related depression
Physically active individuals have an increased sense of accomplishment, or situation-specific self-confidence, which in turn results in reduced depression and reduced fatigue, said Edward McAuley, a professor of kinesiology and community health at Illinois and lead author on the study.

Scientists Celebrate First Physics Results from the LHC
Birmingham physicists have played a key role in producing the first results from CERN's Large Hadron Collider, a 27km underground tunnel near Geneva, where scientists are colliding together particles to discover what happened a millionth of a second after the Big Bang. These results have come out of the ALICE collaboration's detector which will study the physics from ultra-high energy proton-proton and lead-lead interactions.

Some of us may be born more empathetic, new study suggests
BERKELEY — Could it be that the generous Mother Teresa and the miserly Ebenezer Scrooge from “A Christmas Carol” were influenced by their genes? Researchers at the University of California, Berkeley, have found compelling evidence that people who are more empathetic possess a particular variation of the oxytocin receptor gene.

NanoSystems Institute at UCLA to host global symposium on nanobiotechnology
Nanotechnology has shown great promise for applications in the areas of energy, information technology and the environment. In the health and medicine fields, however, its promise has progressed beyond possibility to become reality. Nanoscale research has led to techniques and devices with the potential to revolutionize health care, including imaging tools that detect cancers at the atomic level, nanomachines programmed to release drugs within specific cells, and biosensors that monitor changes from deep within body organs.

Rapid supernova could be new class of exploding star
Rapid supernova could be new class of exploding star
BERKELEY — An unusual supernova rediscovered in seven-year-old data may be the first example of a new type of exploding star, possibly from a binary star system where helium flows from one white dwarf onto another and detonates in a thermonuclear explosion. Artist's impression of an AM-CVn star system, where helium flows from one star, a helium white dwarf (upper right), onto another, piling up in an accretion disk around a small, dense primary star.
