Remotely operated aircraft successfully tested as tool for measuring changes in polar ice sheets

Scientists studying the behavior of the world's ice sheets--and the future implications of ice sheet behavior for global sea-level rise--may soon have a new airborne tool that will allow radar measurements that previously would have been prohibitively expensive or difficult to carry out with manned aircraft.

'Cosmic barometer' could reveal violent events in universe's past

Exploding stars, random impacts involving comets and meteorites, and even near misses between two bodies can create regions of great heat and high pressure.

Misleading mineral may have resulted in overestimate of water in moon

he amount of water present in the moon may have been overestimated by scientists studying the mineral apatite, says a team of researchers led by Jeremy Boyce of the UCLA Department of Earth, Planetary and Space Sciences.

Report: Methane-producing microbes may be responsible for mass extinction

Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out — by far the largest of this planet’s five known mass extinctions. But pinpointing the culprit has been difficult, and controversial.

Wind energy: On the grid, off the checkerboard

As wind farms grow in importance across the globe as sources of clean, renewable energy, one key consideration in their construction is their physical design -- spacing and orienting individual turbines to maximize their efficiency and minimize any "wake effects," where the swooping blades of one reduces the energy in the wind available for the following turbine.

Claim: Using more wood for construction can slash global reliance on fossil fuels

A Yale University-led study has found that using more wood and less steel and concrete in building and bridge construction would substantially reduce global carbon dioxide emissions and fossil fuel consumption.

A breakthrough in creating invisibility cloaks, stealth technology

Controlling and bending light around an object so it appears invisible to the naked eye is the theory behind fictional invisibility cloaks.

NSIDC, NASA say Arctic melt season lengthening, ocean rapidly warming

The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.

NASA releases images of X-class solar flare

The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT March 29, 2014, and NASA's Solar Dynamics Observatory captured images of the event.

Understanding Earth's dynamic interior

Seeking to better understand the composition of the lowermost part of Earth's mantle, located nearly 2,900 kilometers (1,800 miles) below the surface, a team of Arizona State University researchers has developed new simulations that depict the dynamics of deep Earth.

Study: Warming climate may spread drying to a third of Earth

Increasing heat is expected to extend dry conditions to far more farmland and cities by the end of the century than changes in rainfall alone, says a new study.

Claim: Hybrid vehicles more fuel efficient in India and China

What makes cities in India and China so frustrating to drive in—heavy traffic, aggressive driving style, few freeways—makes them ideal for saving fuel with hybrid vehicles, according to new research by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).

Rainbow-catching waveguide could revolutionize energy technologies

More efficient photovoltaic cells. Improved radar and stealth technology. A new way to recycle waste heat generated by machines into energy. All may be possible due to breakthrough photonics research at the University at Buffalo.

Study finds astronauts' hearts become more spherical in space

New findings from a study of 12 astronauts show the heart becomes more spherical when exposed to long periods of microgravity in space, a change that could lead to cardiac problems, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session.

Hubble magnifies the distant universe

Galaxy clusters are some of the most massive structures that can be found in the Universe — large groups of galaxies bound together by gravity.

Cleaner NASA rover sees its shadow in Martian spring

Late afternoon lighting produced a dramatic shadow of NASA's Mars Exploration Rover Opportunity photographed by the rover's rear hazard-avoidance camera on March 20, 2014.

Report: Molecules offer cleaner, milder way to break down natural gas

Scientists have discovered inexpensive materials that can convert natural gas into useful chemicals under mild conditions, a new study in the 14 March issue of the journal Science reports. This approach may eventually compete with technologies for generating the same chemicals from petroleum, a fossil fuel that emits a lot of carbon dioxide into the atmosphere when it burns.

Great earthquakes, water under pressure, high risk

The largest earthquakes occur where oceanic plates move beneath continents. Obviously, water trapped in the boundary between both plates has a dominant influence on the earthquake rupture process.

Revolutionary solar cells double as lasers

Commercial silicon-based solar cells - such as those seen on the roofs of houses across the country - operate at about 20% efficiency for converting the Sun's rays into electrical energy. It's taken over 20 years to achieve that rate of efficiency.

Study finds gaming augments players’ social lives

New research finds that online social behavior isn’t replacing offline social behavior in the gaming community. Instead, online gaming is expanding players’ social lives. The study was done by researchers at North Carolina State University, York University and the University of Ontario Institute of Technology.
