Radio Wave Pasteurization
Using radio waves to pasteurize fruit juices
Gravity Generator
Where does gravity come from? (mass of objects determines gravity, and small particles called gravitons may be the source of that attraction)
Dryer Sheets
How do dryer sheets work? (Releases ingredients that neutralize static charge)
Natural Light Bulbs
What is the make-up of a natural light bulb rather than a normal one? (the mix of colors it gives off)
Muon Detector
A detector for particles called muons could be used to identify smuggled nuclear material.
Gravity Detector
Detecting exploding stars and other stellar events by monitoring minute changes in gravity
Tilted Earth
Why is the Earth tilted? (Got knocked around as it was forming billions of years ago)
Listening to Twisters
Infrasound instruments can detect tornadoes long before traditional means
Mars Dust Devils
Dust devils spotted and sensed by Pathfinder on Mars -- much like Earth counterparts
Rock Art Acoustics
Echoes may have inspired ancient people to paint on cave walls.
Ice Cream Tech Roundup
Acoustic freezer for ice cream parlors cools with sound, and a wireless sensor monitors organ transplants.
Gas Giant Origins
A new model for the formation of gas giant planets explains why so many have been discovered recently.
Spinning World
Why don't human activities make the Earth unbalanced as it spins on its axis? (They don't move as much mass around as natural processes do, except for putting water in reservoirs.)
Changing Neutrinos
Results from the KamLAND experiment show that neutrinos can change Òflavors.Ó
Sun Rings
A new piece by the Kronos Quartet incorporates sounds from outer space.
Acoustics Roundup
Stories from the annual Acoustics Society of America meeting
Microwave Drill
A drill that uses microwaves to quietly bore clean, dust-free holes in non-metallic objects
Rattling Energy
A device that transforms the vibrations of motion into electricity.
Spitballs
What does spit do for a baseball pitcher's spitball? (makes the ball slippery so it doesn't spin)
Kilogram Standard
Engineering a machine to create a lab-reproducible standard for the kilogram
Chameleon Plastic
A non-toxic polymer that changes color when heated to specific temperatures.
