Scientists led by the University of Leicester have set a new record for cosmic X-ray sources ever sighted – creating an unprecedented cosmic X-ray catalogue that will provide a valuable resource allowing astronomers to explore the extreme Universe.
The XMM-Newton Survey Science Centre, led by a team from the University of Leicester's Department of Physics and Astronomy, used the University's 'ALICE' supercomputer to help them produce a new X-ray catalogue, dubbed "3XMM".
PHILADELPHIA - Overturning a commonly-held belief that cities are inherently more dangerous than suburban and rural communities, researchers from the Perelman School of Medicine at the University of Pennsylvania and the Children's Hospital of Philadelphia (CHOP) have found that risk of death from injuries is lowest on average in urban counties compared to suburban and rural counties across the U.S.
WASHINGTON — Large cities in the U.S. are significantly safer than their rural counterparts, with the risk of injury death more than 20 percent higher in the country. A study to be published online tomorrow in Annals of Emergency Medicine upends a common perception that urban areas are more dangerous than small towns ("Safety in Numbers: Are Major Cities the Safest Places in the U.S.?").
The Rancho Fire started 2 miles north of Lebec, CA on July 19, 2013 at approximately noon. While the fire originally started on Kern County jurisdiction, by the evening, it had burned into Los Padres National Forest. The fire has burned 722 acres and is 92% contained. Containment of the fire is expected on July 24, 2013. There are currently 337 resources assigned to the Rancho Fire, including 14 crews, 10 engines, 1 water tender and 2 helicopters. The cause of the fire is still under investigation.
HOUSTON – (July 22, 2013) – Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The "solar steam" sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat.
Forest fires are burning north and east of Russia's Irkutsk Oblast. The Irkutsk Oblast is located in southeastern Siberia in the basins of Angara, Lena, and Nizhnyaya Tunguska Rivers.
NASA's Aqua satellite passed over the area and captured an image showing multiple forest fires and smoke plumes. Some of the places affected by the smoke include Cokhchuolu, Ust'ye-Chony, Skysykatakh, and Chernyshevskiy along the Vilyuy River. These appear to be recreational areas.
South of the Vilyuy River is the town of Mirny. It is known for having the world's largest diamond mine.
Forest fires continue to plague the hot, dry western part of the United States this summer. In Idaho, several fires were spotted by NASA's Aqua satellite on July 20, 2013. Actively burning areas, detected by MODIS's thermal bands, are outlined in red.
In Indonesia, land-clearing blazes dot the countryside. Fires for clearing land have been outlowed for all but the smallest landowners, but the "slash-and-burn" practice still persists despite cloaking Southeast Asia in toxic pollution for weeks. Better and more available satellite technology is helping identify culprits behind land-clearing blazes in Indonesia. Unprecedented levels of air pollution in Singapore and Malaysia in June led to respiratory illnesses, school closings, and grounded aircraft.
Researchers from Aalto University and Paris Tech have placed water droplets containing magnetic nanoparticles on strong water repellent surfaces and have made them align in various static and dynamic structures using periodically oscillating magnetic fields. This is the first time researchers have demonstrated reversible switching between static and dynamic self-assembly.
'We are conducting this line of research because it opens up a way to create new responsive and intelligent systems and materials,' said Dr. Robin Ras of Aalto University, Finland.
The European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO, captured this image of a gigantic coronal hole hovering over the sun's north pole on July 18, 2013, at 9:06 a.m. EDT. Coronal holes are dark, low density regions of the sun's outermost atmosphere, the corona. They contain little solar material, have lower temperatures, and therefore, appear much darker than their surroundings.
NASA's Aqua satellite captured an image of California's Mountain Fire on July 18 as the satellite passed overhead in space.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard Aqua captured an image of the smoke and heat from California's Mountain Fire on July 18 at 21:00 UTC (5 p.m. EDT/2 p.m. PDT). MODIS has the ability to detect hot spots or fires and they appear red in the image. At the time of the image, the light brown smoke plume was blowing west-northwest.
By monitoring artists as they sketch human faces, stroke by stroke, scientists at Disney Research, Pittsburgh, have built computer models that learn each artist's drawing style, how they use strokes and how they select features to highlight as they interpret a face into a portrait.
A better understanding of this abstraction process, the researchers stated, not only is interesting from an artistic point of view, but also can help in developing artificial drawing tools.
Achieving a desired motion in an animated physical character, whether it be a small toy or a full-sized figure, demands highly specialized engineering skills. But research teams at Disney Research have created a pair of software packages that can open the design process to people with a broader spectrum of skills and provide more creative choices.
Providing a "second screen" experience for audiences at movie theaters, stadiums and other public venues need not require a special wireless infrastructure. Instead, a system developed by Disney Research, Zürich, uses the venue's regular sound system to transmit text, games or other information to smartphones using only an audio signal.
In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star's light with ice and snow on the planet's surface.
Stars emit different types of light. Hotter stars emit high-energy visible and ultraviolet light, and cooler stars give off infrared and near-infrared light, which has a much lower energy.
