Hiding in Plain Sight: Detecting Elusive Dark Matter with GPS

The everyday use of a GPS device might be to find your way around town or even navigate a hiking trail; but for two physicists, the Global Positioning System might be a tool in directly detecting and measuring dark matter, so far an elusive but ubiquitous form of matter responsible for the formation of galaxies.

Milestone in Accelerating Particles with Plasma Powerful Enough to Drive Future Accelerators

November 10, 2014 12:40 pm | by SLAC National Accelerator Laboratory | News | Comments

Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los Angeles have shown that a promising technique for accelerating electrons on waves of plasma is efficient enough to power a new generation of shorter, more economical accelerators. This could greatly expand their use in areas such as medicine, national security, industry and high-energy physics research.

Rocket Experiment Finds Surprising Cosmic Light

November 7, 2014 3:37 pm | by Kathy Svitil, Caltech | News | Comments

Using an experiment carried into space on a NASA suborbital rocket, astronomers have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. The researchers say the best explanation is that the cosmic light originates from stars that were stripped away from their parent galaxies and flung out into space as those galaxies collided and merged with other galaxies.

New Model Provides Accurate Traffic Flow Predictions

November 7, 2014 2:46 pm | by David L. Chandler, MIT | News | Comments

A reliable way of predicting the flow of traffic could be a great convenience for commuters, as well as a significant energy-saver. During an emergency evacuation following a natural disaster, reliable predictions of the best routes could even be a lifesaver. Now a team of researchers from MIT, the University of Notre Dame, and elsewhere has devised what they say is an effective and relatively simple formula for making such predictions.

Since 1999, the conjecture by Asher Peres, who invented quantum teleportation, has piqued the interest of many scientists in the field. According to his hypothesis, the weakest form of quantum entanglement can never result in the strongest manifestation of the phenomenon. Today, scientists have proven this conjecture to be false, thus solving one of the most famous problems in quantum information physics.

Now, a new method for improving the thrust generated by such laser-propulsion systems may bring them one step closer to practical use. A new system integrates a laser-ablation propulsion system with the gas blasting nozzles of a spacecraft.

Fusion energy almost sounds too good to be true — zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply. Perhaps the biggest roadblock to adopting fusion energy is that the economics haven’t penciled out. University of Washington engineers hope to change that.

Earth’s Magnetic Field could Flip within a Human Lifetime

Imagine the world waking up one morning to discover that all compasses pointed south instead of north. It’s not as bizarre as it sounds. Earth’s magnetic field has flipped — though not overnight — many times throughout the planet’s history. A new study demonstrates that the last magnetic reversal 786,000 years ago actually happened very quickly, in less than 100 years — roughly a human lifetime.

On October 8, 2014, active regions on the sun combined to look something like a jack-o-lantern’s face. This image is a blend of 171 and 193 angstrom light as captured by the Solar Dynamics Observatory. The active regions appear brighter, because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona.
