Scientists develop heat-resistant materials that could vastly improve solar cell efficiency
Using heat-resistant ceramics, researchers have made a significant advance in thermophotovoltaics, creating electricity from heat. Scientists have created a heat-resistant thermal emitter, an element used in specialized solar cells, that could significantly improve the efficiency of the cells. The novel component is designed to convert heat from the sun into infrared light, which can than be absorbed by solar cells to make electricity – a technology known as thermophotovoltaics.

Tunable antenna could end dropped cell phone calls
Tunable antenna could end dropped cell phone calls
Why do cell phones drop calls? Like a radio dial tuned to different frequencies (stations), cell phone antennas have tuning circuits that quickly switch frequencies when controlled by a voltage applied to a tunable capacitor. Cell phone companies want to improve these circuits to pack more discrete signals into a finite allocation of spectrum and minimize those pesky dropped calls.

Sky Survey Captures Key Details of Cosmic Explosions
Sky Survey Captures Key Details of Cosmic Explosions
Developed to help scientists learn more about the complex nature of celestial objects in the universe, astronomical surveys have been cataloguing the night sky since the beginning of the 20th century. The intermediate Palomar Transient Factory (iPTF)-led by the California Institute of Technology (Caltech)-started searching the skies for certain types of stars and related phenomena in February.

Iron in the Earth's core weakens before melting
Iron in the Earth’s core weakens before melting
The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to understand. Scientists use seismic waves - pulses of energy generated during earthquakes - to measure what is happening in the Earth's inner core, which at 6000 km beneath our feet is completely inaccessible.

Bending world's thinnest glass shows atoms' dance
Bending world's thinnest glass shows atoms' dance
Watch what happens when you bend and break the world's thinnest glass. This glass, discovered by Cornell researchers and their international team of collaborators, was recently featured in the Guinness Book of World Records and is made of the same compounds as everyday windowpanes. Now, a research team led by David A. Muller, professor of applied and engineering physics and co-director of the Kavli Institute at Cornell for Nanoscale Science, and Ute Kaiser, professor at the University of Ulm, has used an electron microscope to bend, deform and melt the one-molecule-thick glass.

Spinning-disk microscope offers window into the centre of a cell
A new method of imaging cells is allowing scientists to see tiny structures inside the 'control centre' of the cell for the first time. The microscopic technique, developed by researchers at Queen Mary University of London, represents a major advance for cell biologists as it will allow them to investigate structures deep inside the cell, such as viruses, bacteria and parts of the nucleus in depth.

Scientists Celebrate Role in Higgs Discovery That Led to Nobel Prize
The Royal Swedish Academy of Sciences today awarded the Nobel Prize in physics to theorists Peter Higgs and Francois Englert to recognize their work developing the theory of what is now known as the Higgs field, which gives elementary particles mass. Thousands of scientists from around the world played a significant role in discovering the particle that proves the existence of the Higgs field, the Higgs boson.

Nobel-winning Higgs discovery has ties to scientists from UChicago, Fermilab and Argonne
The award of the 2013 Nobel Prize in physics specifically honors the work of theorists Peter Higgs and François Englert, who helped predict the existence of the Higgs boson. But the discovery of the particle in 2012 also depended on contributions by thousands of scientists around the world, including many with deep roots in the University of Chicago research community.

In quantum computing, light may lead the way
Light might be able to play a bigger, more versatile role in the future of quantum computing, according to new research by Yale University scientists. A team of Yale physicists has coaxed an unprecedented number of light particles, or photons, to behave quantum mechanically, or to assume more than one state simultaneously, such as "alive" and "dead." In this case, the light is in the form of trapped microwave photons.

New X-ray vision can reveal internal structure of objects
03 Oct 2013 Scientists have developed a new kind of 'X-ray vision' that is able to peer inside an object and map the three-dimensional distribution of its nano-properties in real time. University of Manchester researchers, working with colleagues in the UK, Europe and the US, say the novel imaging technique could have a wide range of applications across many disciplines, such as materials science, geology, environmental science and medical research.

On the Horizon: A Quantum Internet
On the Horizon: A Quantum Internet
A team of scientists in Innsbruck, Austria, made an important step toward distributed quantum computing with cavities linking remote atom-based registers. They demonstrated precise control of the coupling of each of two trapped ions to the mode of an optical resonator. A key goal in quantum computing is the demonstration of a quantum network, that is, a framework for distribution and remote processing of quantum information.

Scientists generate first map of clouds on an exoplanet
Map reveals a lopsided cloud distribution on an extremely hot planet. On the exoplanet Kepler 7b, the weather is highly predictable, an international team of scientists has found: On any given day, the exoplanet, which orbits a star nearly 1,000 light-years from Earth, is heavily overcast on one side, while the other side likely enjoys clear, cloudless weather.

Probing the surface of pyrite
Common mineral gets first detailed examination of its surface electronic properties, thanks to team of MIT researchers. Pyrite - perhaps better known as "fool's gold" for its yellowish metallic appearance - is a common, naturally occurring mineral. It holds promise as a high-tech material, with potential uses in solar cells, spintronic devices and catalysts, but is also a byproduct of corrosion of steel in deep-sea oil and gas wells.

Quantum computers: Trust is good, proof is better
A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology.
