Quantum Fluctuations May be Responsible for the Probability of All Actions

Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles.

Active Supermassive Black Hole Found in Heart of Spiral Galaxy

Despite its appearance, which looks much like countless other galaxies, Messier 106 hides a number of secrets. Thanks to this image, which combines data from Hubble with observations by amateur astronomers Robert Gendler and Jay GaBany, they are revealed as never before.

Researchers Study Quantum Transport in Topological Insulator Hybrid Structures

Topological insulators are novel materials that are insulating in the bulk but have surface states that are conducting. These surface states are topologically protected and possess several intriguing properties with the promise of potential applications.

Retention Theory May Explain Dancing Ribbon of Energetic Neutral Atoms in Space

The vast edges of our solar system – the boundary at the edge of our heliosphere where material streaming out from the sun interacts with the galactic material – is essentially invisible. It emits no light and no conventional telescope can see it. However, particles from inside the solar system bounce off this boundary and neutral atoms from that collision stream inward. Those particles can be observed by instruments on NASA's Interstellar Boundary Explorer (IBEX).

AAS Awards Bruno Rossi Prize for Research on Gamma-Ray Pulsars

To say that Alice Harding, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md., has a passion for pulsars is a bit of an understatement. On Jan. 24, she was named a winner of the 2013 Bruno Rossi prize together with Roger Romani of Stanford University. The award recognizes their work in establishing a theoretical framework for understanding how pulsars emit gamma rays, the most powerful form of light.

Quantum Information Stored in Atom Transferred Onto Particle of Light

Not only do optical fibers transmit information every day around the world at the speed of light, but they can also be harnessed for the transport of quantum information. In the current issue of Nature Photonics, a research team of Innsbruck physicists led by Rainer Blatt and Tracy Northup report how they have directly transferred the quantum information stored in an atom onto a particle of light. Such information could then be sent over optical fiber to a distant atom.

New Microwave Signal Harnessing Circuit May Find Use in Quantum Systems

EPFL scientists have succeeded in capturing a microwave pulse within a chip for several milliseconds before releasing it with little loss. This extraordinary delay normally requires hundreds of miles of electrical cable, as well as amplifiers

International Research Team Hopes to Achieve Loophole-Free Test of Quantum Theory

An assistant professor of physics at Indiana University-Purdue University Indianapolis (IUPUI) will be among a team of international researchers looking to advance the theory of quantum mechanics, a notion challenged by Albert Einstein and pursued by many of the top scientific minds during the past century.

Quantum Cognition and Quantum Biology to be Discussed at Science of Consciousness Conference

In Eastern philosophical traditions, consciousness is intrinsic to the universe, whereas in most Western views consciousness emerges from complex computation. Can these views be reconciled?
