System Enables Direct Data Transmission Between Underwater and Airborne Devices

Today, underwater sensors cannot share data with those on land, as both use different wireless signals that only work in their respective mediums. Radio signals that travel through air die very rapidly in water. Acoustic signals, or sonar, sent by underwater devices...

Question of the Week : Transportation
Will Carbon Fibers Find a New Place in Vehicles?

In a Tech Briefs article last week, Virginia Tech professor Greg Liu spoke about his team’s newly developed porous carbon fibers, and how the material may someday change how vehicles are built and powered.
