NASA Exercises Modification For East Contract

NASA has exercised the first option under its existing contract with Science Applications International Corporation (SAIC) of Huntsville, Ala., to operate the NASA Enterprise Applications Competency Center (NEACC).

NASA Awards Space Station Mission Operations and Integration Services Contract

NASA has selected Teledyne Brown Engineering Inc. of Huntsville, Ala., for its International Space Station mission operations and integration contract.

Beware the Superflare

Getting ready for a devastating solar storm just might require some impossible-seeming physics.

Does probability come from quantum physics?

Ever since Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using quantum theory to explain and understand the nature of waves and particles. But a new article makes the case that these quantum fluctuations actually are responsible for the probability of all actions, with far-reaching implications for theories of the universe.

Light-emitting nano triangles may have applications in optical technology

For the first time, scientists have created single layers of a naturally occurring rare mineral called tungstenite, which they have used to produce a sheet of stacked sulfur and tungsten atoms with unusual photoluminescent properties and with potential for use in optical technologies such as light detectors and lasers.

Using single quantum dots to probe nanowires

Plasmonic antennas will help image and detect bio-particles. This new research helps establish this approach.

Can you predict how a disease will spread in a population?

How, when and where a pathogen is transmitted between two individuals in a population is crucial in understanding and predicting how a disease will spread. New research has laid the foundation for a new generation of zoonotic disease spreading models, which could allow for more targeted prevention strategies.

Robustness of ITER's solenoid conductor confirmed

(Phys.org)—After an intensive effort to improve the capability of ITER's central solenoid conductor, the ITER Organization has concluded that a technically reliable and economically viable solution has been found. This successful result was obtained through a concerted collaborative effort on the part of the ITER Organization, especially with the Domestic Agencies of Japan and the US, and the international superconductivity research community.

Using fibre lasers for ground-breaking particle acceleration technologies

Scientists from the Optoelectronics Research Centre (ORC) at the University of Southampton are part of an international project that is investigating the use of fibre lasers in ground-breaking particle accelerator technologies, such as the Large Hadron Collider (LHC).
