In modern times, we know that the corona is constantly on the move. Made of electrified gas, called plasma, the solar material dances in response to huge magnetic fields on the sun. Structural changes in these magnetic fields can also give rise to giant explosions of radiation called solar flares, or expulsions of solar material called coronal mass ejections, CMEs – which make the corona a particularly interesting area to study.

The twenty-fifth tropical depression of the western North Pacific Ocean season formed today and is already affecting southern Vietnam. NASA's Aqua satellite passed over Tropical Depression 25W and captured a visible image of the storm that showed its northern quadrant raining over the country.

Research out of the University of Cincinnati seeks to measure economic and political policy impacts that unions associated with criminal justice systems – such as police, correctional officers and dispatchers unions – have in their respective states.

That research, titled "Measuring the Effect of Public-Sector Unionization on Criminal Justice Public Policy" by UC criminal justice doctoral students Derek Cohen and Jay Kennedy, will be presented at the American Society of Criminology conference on Nov. 17.

Livermore, Calif. -- Lawrence Livermore National Laboratory (LLNL) researchers have used the Stack Trace Analysis Tool (STAT), a highly scalable, lightweight tool to debug a program running more than one million MPI processes on the IBM Blue Gene/Q (BGQ)-based Sequoia supercomputer.

The debugging tool is a significant milestone in LLNL's multi-year collaboration with the University of Wisconsin (UW), Madison and the University of New Mexico (UNM) to ensure supercomputers run more efficiently.

Like the impact of an elephant herd grazing on grassland, multinational banks shape the financial environment to an extent that far outweighs their small number. And like a contagious person on a transnational flight, when these giant, interconnected banks succumb to financial ills, they are uniquely positioned to infect wide swaths of the financial system.

A new government-funded study is to be carried out into how Britain's roads could be made safer for cyclists to reduce the risk of cycling injuries, encourage more people to use bikes and improve public health.

It's likely that fellow users on your favorite supercomputer have widely varying needs. The applications, compilers, and libraries that you need are probably different from the ones other users need. That is where modern environment module systems come in. A good module system "sets the table " for users by loading the packages each user needs.

The Texas Advanced Computing Center (TACC) has developed an innovative module system that addresses some unique challenges facing modern computing centers.

The aftershock of a stellar explosion rippling through space is captured in this new view of supernova remnant W44, which combines far-infrared and X-ray data from ESA's Herschel and XMM-Newton space observatories.

W44, located around 10 000 light-years away within a forest of dense star-forming clouds in the constellation of Aquila, the Eagle, is one of the best examples of a supernova remnant interacting with its parent molecular cloud.

The rapid growth in "citizen science" projects during the past decade is enabling more and more science enthusiasts, hobbyists, students and other ordinary people to participate in the excitement of real-world scientific research and help solve serious scientific mysteries. That's the topic of the cover story in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.

CAMBRIDGE, Mass. -- On its surface, operating a military drone looks a lot like playing a video game: Operators sit at workstations, manipulating joysticks to remotely adjust a drone's pitch and elevation, while grainy images from the vehicle's camera project onto a computer screen. An operator can issue a command to fire if an image reveals a hostile target, but such adrenaline-charged moments are few and far between.

PARSIPPANY, NJ (November 14, 2012) – Parents may have some new motivations to serve their kids vegetables. A new study, funded by Pinnacle Foods' Birds Eye brand and published in Public Health Nutrition, found that adding vegetables to the plate led to more positive evaluations of both the main entrée and the cook. By simply serving vegetables with dinner, participants believed the main course would taste better and thought the server was more thoughtful and attentive.

Astronomers using ESO's Very Large Telescope and the Canada-France-Hawaii Telescope have identified a body that is very probably a planet wandering through space without a parent star. This is the most exciting free-floating planet candidate so far and the closest such object to the Solar System at a distance of about 100 light-years. Its comparative proximity, and the absence of a bright star very close to it, has allowed the team to study its atmosphere in great detail.

A planet that is not orbiting a star, effectively making it homeless, has been discovered by a team of University of Montreal (UdeM) researchers working with European colleagues and data provided by the Canada-France-Hawaii Telescope (CFHT) and the European Southern Observatory's Very Large Telescope (VLT). "Although theorists had established the existence of this type of very cold and young planet, one had never been observed until today," said Étienne Artigau, an astrophysicist at UdeM.

On Nov. 13, 2012, certain parts of Earth will experience a total solar eclipse, which, like all eclipses, will only be visible when you are aligned in a straight line with the moon and the sun. In this case the eclipse will only be seen from a narrow corridor in the southern hemisphere that is mostly over the ocean but also cuts across the northern tip of Australia. The JAXA/NASA Hinode mission will experience a partial eclipse of the sun near the same time as the observers in Australia.

On Nov. 13, 2012, the sun emitted a mid-level solar flare, peaking at 9:04 p.m. EST.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where Global Positioning System (GPS) and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours.
