This image of the storm system that generated the F-4 tornado in Moore, Oklahoma was taken by NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard one of the Earth Observing System (EOS) satellites. The image was captured as the tornado began its deadly swath.
HOUSTON -- (May 21, 2013) -- Rice University scientists have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color. The breakthrough by a team of theoretical and applied physicists and engineers at Rice's Laboratory for Nanophotonics (LANP) is described this...
Ninety-seven teams from 28 Colorado schools participated in today's car competitions hosted by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL). The student teams raced solar and lithium ion powered vehicles they designed and built themselves.
Scientists have discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life. This water could be some of the oldest on the planet and may even contain life. Not just that, but the similarity between the rocks that trapped it and those on Mars raises the hope that comparable life-sustaining water could lie buried beneath the red planet’s surface.
When did the first stars and galaxies form in the universe? How brightly did they burn their nuclear fuel? The first massive stars to form in the universe produced copious ultraviolet light that ionized gas from neutral hydrogen. CIBER observes in the near infrared, as the expansion of the universe stretched the original short ultraviolet wavelengths to long near-infrared wavelengths today.
This 120x photo of Radiolaria shells received an honorable mention in the 2012 Nikon Small World Photomicrophotography Competition. It was taken by Ralph Claus Grimm of Jimboomba, Queensland, Australia, using a darkfield technique.
The Twin Rectangular Jet model, installed on the Nozzle Acoustic Test Rig in the Aeroacoustic Propulsion Laboratory at NASA's Glenn Research Center, is being tested to determine the acoustic impact of engine configurations on low sonic boom aircraft for the High Speed Project of the Fundamental Aeronautics Program.
Intel joined the National Institute of Standards and Technology (NIST) in a National Cybersecurity Center of Excellence (NCCoE) partnership, along with 10 other industry leaders: Cisco, HP, HyTrust, McAfee, Microsoft, RSA, Splunk, Symantec, Vanguard and Venafi.
Pulsars have a number of unusual qualities. Like zombies, they shine even though they're technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations.
RICHLAND, Wash. – Enough Northwest wind energy to power about 85,000 homes each month could be stored in porous rocks deep underground for later use, according to a new, comprehensive study. Researchers at the Department of Energy's Pacific Northwest National Laboratory and Bonneville Power Administration identified two unique methods for this energy storage approach and two eastern Washington...
A humanoid robot can receive an object handed to it by a person with something approaching natural, human-like motion thanks to a new method developed by scientists at Disney Research, Pittsburgh in a project partially funded by the International Center for Advanced Communication Technologies (interACT) at Carnegie Mellon University and Karlsruhe Institute of Technology (KIT).
Supplying energy to the American people is an increasingly complex task. These complexities include not just the conversion of the various forms of energy (oil, gas, wind, hydropower, etc.) into useful forms (transportation fuel and electricity) but also moving the more useful form to where it can be used (transmission). Economics and government regulations complicate the matter further.
This 10x photo shows the dorsal view of a female deep-sea copepod (Pontostratiotes sp.) collected in the southeastern Atlantic at a depth of 5395 meters. The image received an honorable mention in the 2012 Nikon Small World Photomicrophotography Competition.
This photo shows a single optical section through the whole gut of a fruit fly (Drosophila melanogaster) larva expressing a reporter for Notch signaling pathway activity (green), and stained with cytoskeletal (red) and nuclear (blue) markers.
The COMSOL Multiphysics 4.3b simulation platform features application-specific modules, including Multibody Dynamics, Wave Optics, Molecular Flow, and Semiconductor and Electrochemistry.
Physicists may have created the smallest drops of liquid ever made in the lab. That possibility has been raised by the results of a recent experiment conducted by Vanderbilt physicist Julia Velkovska and her colleagues at the Large Hadron Collider, the world's largest and most powerful particle collider located at the European Laboratory for Nuclear and Particle Physics (CERN) in Switzerland.
RENO, Nev. – A new window into the nature of the universe may be possible with a device proposed by scientists at the University of Nevada, Reno and Stanford University that would detect elusive gravity waves from the other end of the cosmos. Their paper describing the device and process was published in the prestigious physics journal Physical Review Letters.
Nanomaterials exhibit unique properties that can only unfold when the structures of the material are very small – that is, at the nanoscale. In order to exploit these special properties such as, for example, specific quantum effects it is very important to produce predefined nanostructures in a controlled way and interpret the formation of their shape. Scientists try to understand how to initiate...

Researchers of the Fraunhofer Institute for Applied Solid State Physics and the Karlsruhe Institute for Technology have achieved the wireless transmission of 40 Gbit/s at 240 GHz over a distance of one kilometer. Their most recent demonstration sets a new world record and ties in seamlessly with the capacity of optical fiber transmission.
Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across. Researchers have identified 248 new impact sites on parts of the Martian surface in the past decade
Much like the inside of an operating room, in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their lives. That part of the eyes, the MIRI, or Mid-Infrared Instrument, will glimpse the formation of...
Chances are you know how many miles your car logs for each gallon or tankful of gas, but you probably have only a foggy idea of how much energy your house consumes, even though home energy expenditures often account for a larger share of the household budget.
Writing in Nature, a large international team led Dr Roman Gorbachev from The University of Manchester shows that, when graphene placed on top of insulating boron nitride, or 'white graphene', the electronic properties of graphene change dramatically revealing a pattern resembling a butterfly. The pattern is referred to as the elusive Hofstadter butterfly that has been known in theory for many...
