Hadley Crater provides deep insight into Martian geology Posted: 06 Sep 2012 04:14 PM PDT Recently engaged in providing support to the successful landing of NASA's Mars Science Laboratory's Curiosity rover, ESA's Mars Express has now returned to its primary mission of studying the diverse geology and atmosphere of the 'Red Planet' from orbit. Earlier this year, the spacecraft observed the 120 km wide Hadley Crater, providing a tantalizing insight into the martian crust. The images show multiple subsequent impacts within the main crater wall, reaching depths of up to 2600 m below the surrounding surface.

NASA Mars rover Curiosity begins arm-work phase Posted: 06 Sep 2012 04:05 PM PDT After driving more than a football field's length since landing, NASA's Mars rover Curiosity is spending several days preparing for full use of the tools on its arm.

Quantum world only partially melts: Ultracold atoms reveal surprising new quantum effects Posted: 06 Sep 2012 11:18 AM PDT Scientists are investigating the transition of quantum systems as they approach thermal equilibrium. Scientists have now detected an astonishingly stable intermediate state between order and disorder.

What light through yonder tiny window breaks? Researchers optimize photoluminescent probes to study dna and more Posted: 06 Sep 2012 10:14 AM PDT Sorting good data from bad is critical when analyzing microscopic structures like cells and their contents, according to researchers. The trick is to find the right window of time through which to look. A new paper offers a methodology to optimize the sensitivity of photoluminescent probes using time-resolved spectroscopy. Researchers found their technique gave results nearly twice as good as standard fluorescence spectroscopy does when they probed for specific DNA sequences.

Mining the blogosphere: Researchers develop tools that make sense of social media Posted: 06 Sep 2012 10:13 AM PDT Can a computer "read" an online blog and understand it? Several computer scientists are helping to get closer to that goal.

Mars's dramatic climate variations are driven by the Sun Posted: 06 Sep 2012 08:26 AM PDT On Mars's poles there are ice caps of ice and dust with layers that reflect to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars's north pole to variations in solar insolation, thus established the first dated climate history for Mars, where ice and dust accumulation has been driven by variations in insolation.

Forcing the molecular bond issue: New and improved model of molecular bonding Posted: 06 Sep 2012 06:28 AM PDT Researchers have developed a first-of-its-kind model for providing a comprehensive description of the way in which molecular bonds form and rupture. This model enables researchers to predict the "binding free energy" of a given molecular system, a key to predicting how that molecule will interact with other molecules.

Math tree may help root out fraudsters: Applying algorithm to social networks can reveal hidden connections criminals use to commit fraud Posted: 06 Sep 2012 06:28 AM PDT Fraudsters beware: The more your social networks connect you and your accomplices to the crime, the easier it will be to shake you from the tree. The Steiner tree, that is. In a new article, researchers outlined the connection linking fraud cases and the algorithm designed by Swiss mathematician Jakob Steiner.

Turning ideas into products faster Posted: 06 Sep 2012 06:27 AM PDT Scienitists have engineered and built a system which produces reverse osmosis membrane elements for water treatment in record time. Virtual engineering allowed research and development to proceed simultaneously.

Odd galaxy couple on space voyage Posted: 06 Sep 2012 06:25 AM PDT Two very different galaxies drift through space together in a new image taken by NASA's Hubble Space Telescope. The peculiar galaxy pair is called Arp 116.

Mathematicians offer unified theory of dark matter, dark energy, altering Einstein field equations Posted: 06 Sep 2012 06:20 AM PDT A pair of mathematicians have proposed a unified theory of dark matter and dark energy that alters Einstein's equations describing the fundamentals of gravity. They suggest the law of energy and momentum conservation in spacetime is valid only when normal matter, dark matter and dark energy are all taken into account. For normal matter alone, energy and momentum are no longer conserved, they argue.

In quest of the cosmic origins of silver: Silver and gold materialized in different stellar explosions Posted: 06 Sep 2012 04:40 AM PDT In the quest for the cosmic origins of heavy elements, a researcher has established that silver can only have materialized during the explosion of clearly defined types of star. These are different from the kind of stars producing gold when they explode. The evidence for this comes from the measurement of various high-mass stars with the help of which the stepwise evolution of the components of all matter can be reconstructed.

Cool idea: Potential one-third cut in data centres' energy bills Posted: 06 Sep 2012 04:39 AM PDT Nanyang Technological University (NTU) and Toshiba have developed an advanced cooling technology that will enable data centers to be more energy efficient, cutting energy bills by one-third. Researchers are now test-bedding a new data center that combines Toshiba's air cooling technology with NTU's advanced info-communications technology.
