Creating 21st Century Video Games - November 01, 2007
A computer science student created an updated form of the classic video game Pong. The ball appears to move unpredictably, but is actually governed by algorithms that analyze the fluid dynamics of actual plasmas. Careful programming that considers the plasmaýs mathematical properties allows players to activate a vacuum effect or plasma jet that moves the ball in physically realistic ways as well.

Flying and Radiation Risk - September 01, 2005
At the high altitudes and latitudes commercial airlines fly, crews are subjected to higher-than-normal radiation levels from the sun and cosmic rays. Physicist Robert Barish believes airline crew members are exposing themselves to more radiation than almost any other occupation and is calling for the airline industry to better educate workers about radiation.

Weather System Protects Homeland Security - May 01, 2005
Homeland security officials are tapping researchers' capability to predict the paths of toxic waste spills and hazardous airborne particles. Using computer science and mathematics, along with information on the wind and other climate, they can make estimates of how the toxin will disperse and where the plume will go.

Spotting Sunspots - July 01, 2004
Sunspots, large dark spots that dot the Sun's surface, reach a peak every 11 years, unleashing magnetic storms and solar flares that can disrupt communications. A new model focuses on electrified gas -- or plasma -- that flows around the sun because the plasma holds onto magnetic information from past sunspots.

Protecting Your Privacy - February 01, 2004
The physics of quantum cryptography is the basis for Quantum Privacy Network (QPN). This network can send a message that is hacker proof. Photons are attached to each message. If a hacker intercepts the message the photon is removed and the sender and receiver are alerted that the message has been intercepted.

Meddling Microwaves - February 01, 2004
Physicists discovered that magnets stop the static caused by interference between your cordless telephone and microwave. Microwaves produce a number of unwanted frequencies, which can interfere with your calls. By placing magnets along the microwave's magnetron, the extra frequencies are reduced keeping calls static free.
