Quantum Dots Pose a Significant Competitive Threat to OLED Technology

Glen Allen: According to "Market Opportunities for Quantum Dots: 2015 to 2022," a new report from industry analyst firm NanoMarkets, quantum dots have now progressed far enough down the curve to pose a significant competitive threat to OLED technology.

Role of Ostwald Ripening in Bubble Formation May Help Address Future Energy Needs

Uncork a bottle of champagne, and as the pressure of the liquid is abruptly removed, bubbles immediately form and then rapidly begin the process of "coarsening," in which larger bubbles grow at the expense of smaller ones.

All Stars Appear to be About the Same Age in Large Middle-Aged Clusters

An examination of middle-aged star clusters reveals an unexpectedly narrow age range among their stars, suggesting that large groups of stars evolve differently than previously understood

Black Holes Don't Have to be Very Powerful to Shut Down Star Formation

High-energy jets powered by supermassive black holes can blast away a galaxy's star-forming fuel, resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet containing little or no hydrogen gas to create new ones.

New Way to Emit and Control Quantum Light Generated Using a Silicon Chip

A team of researchers from the University of California, San Diego have demonstrated a way to emit and control quantum light generated using a chip made from silicon—one of the most widely used materials for modern electronics.

Possible Method to Determine Involvement of Higgs Boson in Matter-Antimatter Imbalance

Several experiments, including the BaBar experiment at the Department of Energy's SLAC National Accelerator Laboratory, have helped explain some – but not all – of the imbalance between matter and antimatter in the universe. Now a SLAC theorist and his colleagues have laid out a possible method for determining if the Higgs boson is involved.

Voyager 1 Experiences Three "Tsunami Waves" in Interstellar Space

The "tsunami wave" that NASA's Voyager 1 spacecraft began experiencing earlier this year is still propagating outward, according to new results. It is the longest-lasting shock wave that researchers have seen in interstellar space.

Rocky Exoplanets Stretched out by Gravity of the Stars

Astronomers could soon be able to find rocky planets stretched out by the gravity of the stars they orbit, according to a group of researchers in the United States. The team, led by Prabal Saxena of George Mason University, describe how to detect these exotic worlds in a paper in the journal Monthly Notices of the Royal Astronomical Society.

Future Quantum Computers Could be Connected to a 'Quantum Internet'

In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a 'quantum internet'. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum internet is control of the shape of these photons.

Quantum Mechanics Harnessed to Create Fraud-Proof Credit Cards

Credit card fraud and identify theft are serious problems for consumers and industries. Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial data and personal information from criminal activity. Fortunately, new insights into quantum physics may soon offer a solution.

Most Terrestrial Gamma-Ray Flashes Also Generate Strong Bursts of Radio Waves

Each day, thunderstorms around the world produce about a thousand quick bursts of gamma rays, some of the highest-energy light naturally found on Earth. By merging records of events seen by NASA's Fermi Gamma-ray Space Telescope with data from ground-based radar and lightning detectors, scientists have completed the most detailed analysis to date of the types of thunderstorms involved.
