Never say never in the nano-world

Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules.

Magnetic anomaly deep within Earth's crust reveals Africa in North America

The repeated cycles of plate tectonics that have led to collision and assembly of large supercontinents and their breakup and formation of new ocean basins have produced continents that are collages of bits and pieces of other continents.

Claim: Coffee consumption reduces mortality risk from liver cirrhosis

New research reveals that consuming two or more cups of coffee each day reduces the risk of death from liver cirrhosis by 66%, specifically cirrhosis caused by non-viral hepatitis.

Why Arctic ice is disappearing more rapidly than expected

A new study led by Lance Lesack, a Simon Fraser University geographer and Faculty of Environment professor, has discovered unexpected climate-driven changes in the mighty Mackenzie River’s ice breakup. This discovery may help resolve the complex puzzle underlying why Arctic ice is disappearing more rapidly than expected.  

Report: Americans using more energy

Americans used more renewable, fossil and even nuclear energy in 2013, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory.

Knowledge transfer: Computers teach each other Pac-Man

Researchers in Washington State University’s School of Electrical Engineering and Computer Science have developed a method to allow a computer to give advice and teach skills to another computer in a way that mimics how a real teacher and student might interact.

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.

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.

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.

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.

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.

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.

A new angle on controlling light

Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color or polarization, selectivity based on the direction of propagation has remained elusive.

Computing with slime

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors.
