NASA to Televise Mars Curiosity Rover Science Update Sept. 27

NASA will host a news conference at 11 a.m. PDT (2 p.m. EDT) Thursday, Sept. 27, to present science findings from the Curiosity rover's mission to Mars' Gale Crater.

Researchers study black holes to measure photon mass

(—A global team of scientists, including a University of Mississippi physicist, has determined the best constraint on the mass of photons so far, using observations of super-massive black holes.

Best constraint on mass of photons, using observations of super-massive black holes

A global team of scientists has determined the best constraint on the mass of photons so far, using observations of super-massive black holes. The researchers found a way to use astrophysical observations to test a fundamental aspect of the Standard Model -- namely, that photons have no mass -- better than anyone before.

Thirteenth volume of Einstein papers released

In the fall of 1922, when Albert Einstein's Nobel Prize in Physics was announced, the already-famous physicist was on a steamer headed for Japan. The detailed and poetic travel diary he kept during his journey to Japan, Palestine, and Spain is among the documents included in the latest volume in the Einstein Papers Project, The Collected Papers of Albert Einstein: Volume 13: The Berlin Years: Writings & Correspondence, January 1922–March 1923 (Documentary Edition), which will be released September 25. 

Small X-band photoinjector packs powerful punch

(—Accelerator physicists at SLAC have started commissioning the world's most compact photoinjector – a device that spits out electrons when hit by light. Photoinjectors are used to generate electrons for free-electron lasers (FELs) like the Linac Coherent Light Source, among other things, and this development could enable much more compact FELs, as well as other types of accelerator-based facilities.

Burying the hatchet in the laser lab

Experts have been heavily discussing why exactly electrically insulating materials insulate as they do. Based on different mechanisms, a classification scheme for insulators has been in use since the 1960s -- a theoretical one. However, it has been yet impossible to distinctly classify all insulators due to a lack of suitable experimental approaches. A team of physicists has now developed a new method to distinguish different insulators unambiguously.

Novel materials become multifunctional at ultimate quantum limit

Physicists have examined the lower limits of novel materials called complex oxides and discovered that unlike conventional semiconductors the materials not only conduct electricity, but also develop unusual magnetic properties.

OPTIMUS PRIME Spinoff Video Contest Coming

NASA is set to begin its third annual NASA OPTIMUS PRIME Spinoff Video Contest to help raise student awareness and understanding of NASA technologies and their many benefits to the public and our everyday lives.

NASA Selects Contract for Aerospace Modeling and Simulation

NASA has selected Science Applications International Corp. of McLean, Va., to receive a contract to support the aerospace systems modeling and simulation facilities at the agency's Ames Research Center, Moffett Field, Calif.

NASA Opens Accreditation to Social Media for Spacex Launch

NASA is inviting social media users to apply for credentials for the Oct. 7 launch of the first contracted cargo resupply flight to the International Space Station under NASA's Commercial Resupply Services contract.
