Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon's largest impact crater.
About 65 million years ago, an asteroid or comet crashed into a shallow sea near what is now the Yucatán Peninsula of Mexico. The resulting firestorm and global dust cloud caused the extinction of many land plants and large animals, including most of the dinosaurs.
Scientists from U of T's Department of Chemistry have discovered a novel chemical lurking in the atmosphere that appears to be a long-lived greenhouse gas (LLGHG). The chemical – perfluorotributylamine (PFTBA) – is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to impact climate.
Heating a sheet of plastic may not bring it to life – but it sure looks like it does in new experiments at Rice University. The materials created by Rice polymer scientist Rafael Verduzco and his colleagues start as flat slabs, but they morph into shapes that can be controlled by patterns written into their layers.
A stopwatch made of light can determine the duration of extremely brief electron flashes. Teams based in the Laboratory for Attosecond Physics (LAP) at LMU and at the Max Planck Institute of Quantum Optics have, for the first time, succeeded in measuring the lengths of ultrashort bursts of highly energetic electrons using the electric fields of laser light.
Rivers and streams release carbon dioxide at a rate five times greater than the world's lakes and reservoirs combined, contrary to common belief. Research from the University of Waterloo was a key component of the international study, the findings of which appear in a recent issue of the journal Nature.
Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life, in research published today in the journal Science.
The region located between the surface of the sun and its atmosphere has been revealed as a more violent place than previously understood, according to images and data from NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS.
Converting sunshine into electricity is not difficult, but doing so efficiently and on a large scale is one of the reasons why people still rely on the electric grid and not a national solar cell network.
Who knows how economical it might be, but the Japanese electronics and industrial giant Hitachi is moving toward marketing an energy storage system that could be a companion piece to renewable power generation – another sign of the growing interest in such products.
The prospect of turning coal into fluorescent particles may sound too good to be true, but the possibility exists, thanks to scientists at Rice University.
Popular television shows such as “Doctor Who” have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU’s Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past.
Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics — so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a distance."
NASA's visualization (video) below shows the position of the sun's magnetic fields from January 1997 to December 2013.
Two tiny, cube-shaped research satellites hitched a ride to Earth orbit to validate new hardware and software technologies for future NASA Earth-observing instruments.
The cube satellites, or “CubeSats,” which typically have a volume of exactly 33.814 ounces (1 liter), were launched on a United Launch Alliance Atlas V rocket late last week from California's Vandenberg Air Force Base as part of the NROL-39 GEMSat mission.
How up would you be for buying a Toyota Prius convertible? That was one of the primary under the radar surprises Toyota showcased at the recent Tokyo Motor Show in the form of the Aqua Air concept.
One of the funny things about the wind-power-and-birds controversy is that the folks who most frequently raise the issue are political conservatives who otherwise show little regard for the state of wildlife or the environment.
There is about 30% difference between any two people's sense of smell. New research shows that our olfactory senses are as different as our DNA.
It's really, really thin. It's tough as lead boots. It's sexy. It's graphene. And, the science world gets all hot and heavy when it is around. Brainiacs just love the super-material.
He found that by adding organic layers between layers of zinc it is possible to improve the performance of thermoelectric materials. The organic layers are also believed to have a major effect in reducing thermal conductivity, which would be very useful in thermoelectric materials.
