MESSENGER Provides New Insights on Mercury

Data from the MESSENGER spacecraft's first flyby of Mercury in January of 2008 are now turning into science results. Several scientists discussed their findings at a press conference today highlighting the MErcury Surface, Space ENvironment, GEochemistry, and Ranging mission, the first spacecraft to visit Mercury since NASA's Mariner 10 made three flyby passes in 1974 and 1975. Among the findings, scientists discovered volcanism has played a more extensive role in shaping the surface of Mercury than previously thought. MESSENGER data has also identified and mapped surface rock units that

Mercury's Surface Dominated By Volcanism And Iron-deficiency

Volcanism has played a more extensive role in shaping the surface of Mercury than scientists had thought. This result comes from multispectral imaging data gathered in January 2008 by MESSENGER, the latest spacecraft to visit the sun's innermost planet.

Volcanic Activity Shaped Mercury After All

A research team led by Brown University planetary geologist James Head has determined that volcanism played a central role in forming Mercury’s surface. The evidence of volcanic activity lends important insights into Mercury’s geologic history and appears in a special section describing the MESSENGER mission’s recent flyby of Mercury in the July 4 issue of Science.

First Results From Messenger's Mercury Flyby

Several readers noted the special section in Science, published today, with results from Messenger's flyby of Mercury last January. One conclusion is that volcanism has shaped the planet, contrary to earlier theories that Mercury had been "dead on arrival." The LA Time's coverage highlights the finding that Mercury has shrunk by a mile in diameter over its lifetime, due to shrinkage at its core.

Brand-new view of volcanism on mercury

Washington - Volcanic activity has played a central role in forging the surface of Mercury, scientists said on Thursday based on data collected by a Nasa spacecraft that zoomed past the closest planet to the sun in January.

Liquid Mirror Telescopes Set For Magnetic Upgrade

KentuckyFC writes "Liquid mirror telescopes start life as a puddle of mercury in a bowl. Set the bowl spinning and the mercury spreads out in a thin film giving the surface an almost perfect mirror finish. But these telescopes have two important limitations. First, they can only point straight up since tilting the mirror spills the mercury. And second, they cannot be made adaptive to correct for any blurring introduced by the Earth's atmosphere. But liquid mirror telescopes look set for an upgrade thanks to the work of a group of Canadian researchers. Their technique is to change the shape of the liquid mirror using powerful electromagnets. They use a ferromagnetic fluid of iron nanoparticles in oil instead of mercury which is too dense to be easily manipulated in this way.

Panasonic Shows Off Surface-Like Digital Wall

Microsoft's getting some competition for its Surface device. Panasonic is showing off a very Surface-like product it's calling Digital Wall, and it's exactly what it sounds like. While at this point it doesn't appear to offer all the the features of Surface it could also come in much cheaper that the Microsoft version, and for many people that's the key. Hit the jump for a short video of the Digital Wall in action. [Digital World Tokyo]

NASA reveals new discoveries about Mercury

NASA announced that recent analysis of data from a January 2008 flyby of the planet Mercury by the Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) spacecraft shows that volcanoes were involved in plains formation and suggest that its magnetic field is actively produced in the planet's core.

Instrument Shows What Planet Mercury Is Made Of

By measuring the charged particles in the planet Mercury's magnetic field, a University of Michigan sensor enabled the first observations about the surface and atmospheric composition of the closest world to the sun.

Panasonic develops Digital Wall surface computer...

Panasonic is working on a wall-mounted surface computer with an enormous touchscreen. What the company aptly calls the Digital Wall is reportedly twice the size of a normal 110-inch display, and allows users to drag folders and windows across it. Unlike the similar Microsoft TouchWall currently under development, which is based on its Surface computing technology, the Digital Wall does not yet support multi-touch inputs, although Panasonic is said to be working on it.

Volcanic eruptions helped shape planet Mercury: study

WASHINGTON (AFP) - Volcanic activity played a key role in shaping the planet Mercury's crater-riddled surface, and not asteroid impacts as previously theorized, according to US research published Thursday.

MESSENGER Scientists 'Astonished' to Find Water in Mercury's Thin Atmosphere

Molecular Profiles Demonstrates Technique for Measuring Surface Physical Properties of Pharmaceutical Materials for Inhalation

(Nottingham UK, 26 June, 2008) - Molecular Profiles, a global leader in the provision of innovative contract research services to the pharmaceutical, biopharmaceutical and biomedical sectors worldwide, announces a new poster to demonstrate the ability of nanoPASS (nanoscale Predictive Analytical Screening Solution) to characterise the surface energy of an API material. nanoPASS, an innovative new service platform, was launched earlier this year as a new addition to Molecular Profiles' nanoscale analytical services offering. This poster entitled "Measuring Surface Physical Properties of Pharmaceutical Materials for Inhalation: Physical Changes During the Size Reduction Process" was recently presented at Respiratory Drug Delivery 2008, Arizona, USA.

Nanotechnology paper for switchable surfaces

(Nanowerk Spotlight) Generally, a surface either loves a liquid drop (then it's called solvophilic – wetting) or hates it (called solvophobic – repulsion) when it lands, depending on several parameters of both the surface – like geometric roughness asperities or ups and downs and chemical composition – and the liquid – like surface tension or tendency of solvation. When water is the liquid the terms hydrophilic and hydrophobic are used respectively for this and for oil similar terms like oleophilic and oleophobic.
