3 Theories That Might Blow Up the Big Bang
One theory says our universe is a tissue flying through "The Bulk." A second says the arrow of time points "forwards" for some universes and "backwards" for others. A third says that time doesn't exist at all—the universe is a bunch of connected "Nows," like integers on a number line.

'Superdense' coding gets denser 
The record for the most amount of information sent by a single photon has been broken by researchers at the University of Illinois. Using the direction of “wiggling” and “twisting” of a pair of hyper-entangled photons, they have beaten a fundamental limit on the channel capacity for dense coding with linear optics.

Physicists show electrons can travel over 100 times faster in graphene than in silicon
University of Maryland physicists have shown that in graphene the intrinsic limit to the mobility, a measure of how well a material conducts electricity, is higher than any other known material at room temperature. Graphene, a single-atom-thick sheet of graphite, is a new material which combines aspects of semiconductors and metals.

Physicists team up to learn how quantum mechanical states break down
Researchers at the U. S. Department of Energy’s Ames Laboratory, the University of California, Santa Barbara, and Microsoft Station Q have made significant advancements in understanding a fundamental problem of quantum mechanics – one that is blocking efforts to develop practical quantum computers with processing speeds far superior to conventional computers.

A sub-femtosecond stop watch for 'photon finish' races
Using a system that can compare the travel times of two photons with sub-femtosecond precision researchers have found a remarkably large difference in the time it takes photons to pass through nearly identical stacks of materials with different arrangements of refractive layers.

Nanomaterials show unexpected strength under stress
In yet another twist on the strangeness of the nanoworld, researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park have discovered that materials such as silica that are quite brittle in bulk form behave as ductile as gold at the nanoscale. Their results may affect the design of future nanomachines.

Modern physics is critical to global warming research
Science has come a long way with predicting climate. Increasingly sophisticated models and instruments can zero in on a specific storm formation or make detailed weather forecasts – all useful to our daily lives. But to understand global climate change, scientists need more than just a one-day forecast. They need a deeper understanding of the complex and interrelated forces that shape climate.

Stunt doubles: Ultracold atoms could replicate the electron 'jitterbug'
Ultracold atoms moving through a carefully designed arrangement of laser beams will jiggle slightly as they go, two NIST scientists have predicted.* If observed, this never-before-seen “jitterbug” motion would shed light on a little-known oddity of quantum mechanics arising from Paul Dirac’s 80-year-old theory of the electron.

Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts — belts consisting of high-energy electrons that can damage satellites and spacecraft and pose a risk to astronauts performing activities outside their spacecraft.
