Research and Markets has announced the addition of the "Market Opportunities for Quantum Dots in Lighting and Displays" report to their offering.
Ever wonder how the hot soup of subatomic particles that filled the early universe transformed into the ordinary matter of today’s world? Nuclear physicists exploring this question can’t exactly travel back 13.8 billion years to watch what really happened, but they can recreate matter at the extreme temperatures and densities that existed just after the Big Bang by smashing together ordinary atomic nuclei at the Relativistic Heavy Ion Collider (RHIC).
When ice is warmed, the water molecules forming its structure vibrate more and more vigorously until finally the forces between them are no longer strong enough to hold them together – the ice melts and turns into liquid water. Quantum physics predicts that similar phenomena can be observed if the quantum mechanical fluctuations of the particles in a material can be altered.
Two graduate students in the Rochester Institute of Technology astrophysical sciences and technology program were recognized with Chambliss Astronomy Achievement Student Awards for their outstanding research posters at the 223rd American Astronomical Society meeting in Washington, D.C., in January.
The nature of consciousness, the reality it conveys and our place in the universe remain unknown. Since ancient times, two types of views have approached these questions. In Western science and philosophy, consciousness is strictly a by-product of brain activity, the reality it perceives not to be trusted (‘Plato’s cave’, Descartes’ ‘brain-in-a-vat’, Dennett’s ‘multiple drafts’). On the other hand, in Eastern philosophy, consciousness is primary, the fundamental basis for reality.
Perimeter Institute hosted the Honourable John Milloy, MPP for Kitchener Centre, as he named 20 local recipients of Ontario’s Early Researcher Awards (ERAs), which support highly promising early-career faculty with $140,000 grants. The program’s goal is to improve Ontario’s ability to attract and retain the best and brightest research talent from around the world.
Dr. Kendall Reeves, a research scientist in the UT Dallas Department of Physics, has taken a leadership role in one of the world’s largest science experiments.
Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky Way galaxy. These black holes feed on gas and dust all the time, but astronomers rarely get to see mealtime in action.
A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using public data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the Harvard-Smithsonian Center for Astrophysics (CfA), the Massachusetts Institute of Technology (MIT) and the University of Chicago have developed new maps showing that the Galactic center produces more high-energy gamma rays than can be explained by known sources and that this excess emission is consistent with some forms of dark matter.
NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe and found that it definitely lives up to its nickname: El Gordo (Spanish for "the fat one").
Secure mobile communications underpin our society and through mobile phones, tablets and laptops we have become online consumers. The security of mobile transactions is obscure to most people but is absolutely essential if we are to stay protected from malicious online attacks, fraud and theft.
The centimeter-sized fragments and smaller particles that make up the regolith — the layer of loose, unconsolidated rock and dust — of small asteroids is formed by temperature cycling that breaks down rock in a process called thermal fatigue, according to a paper published today in the Nature Advance Online Publication.
When it comes to looking at reality from the subatomic perspective of quantum theory, many physicists are nearly as much in the dark as the average person on the street.
Grammy-winning jazz legend and sax virtuoso WAYNE SHORTER took a few hours off recently from a busy weekend of sold-out shows at the SFJazz Center in San Francisco to indulge in his second love – the cosmos. In fact, all four members of the Wayne Shorter Quartet left a rainy Saturday afternoon behind to take an impromptu tour of the universe, courtesy of jazz fans TOM ABEL and RISA WECHSLER, who are Stanford professors of physics and astrophysicists at Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford’s SLAC National Accelerator Laboratory.

NASA has selected seven scientists as recipients of the 2014 Carl Sagan Exoplanet Postdoctoral Fellowships. The fellowship, named for the late astronomer, was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars.
