Flying and Radiation Risk
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

Physics Of Sailing
Physicists know the secrets
of sailing that many novice
sailors do not. A boat does
not go fastest when the wind
blows from directly behind
it, but when the wind comes
from the side. With the
sails at the correct angle,

New Combat Helmet
Wearing a helmet can make it
hard to figure which
direction sounds -- such as
gunfire -- is coming from.
Soldiers in Iraq are using a
new helmet, called the
Advanced Combat Helmet,
which is padded internally

Sniffing Out Bombs
A tiny sensor that monitors
electrical conductivity
allows scientists to detect
the presence of explosives.
The sensor measures the
conductivity of two
different thin films, one
made of a cobalt compound

Meteorologists Use Weather Knowledge to Predict Path of Toxic Spills
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 ... > more -
Computer Scientists Develop Portable Evidence-Gathering Tool
Investigators on a crime scene can now use a new tool for collecting chemical or biological samples. The sampler gun collects samples on a cotton pad -- eliminating direct contact with anything ... > more -
Mathematician Calms The Skies With Turbulence Detection Algorithm
A mathematician developed a system that creates a three-dimensional view of turbulence and transmits it to airliner cockpits. The new algorithm analyzes data gathered by Next Generation Doppler ... > more -
Rheologists Apply Shear-Thickening Fluids to Protective Gear
Rheologists have created a new way of bullet-proofing clothes using shear-thickening fluids. Fabric treated with shear-thickening granular suspensions can turn soft material into solid protective ... > more -
Engineers Develop Technique for Recognizing Gun Owner's Grip
Researchers have designed, built and tested a handgun that will fire only when its component circuitry and software recognize the grip of an authorized shooter. The technology measures not only the ... > more -
New Software Helps Track the Path of Toxic Spills
Ecological engineers have developed software that can model the path of a toxic spill in waterways anywhere in the United States. The system can predict if and when a contaminant will reach a ... > more -
Engineers Develop Non-Acoustical Sensor to Improve Battlefield Communication
A new device will soon help troops communicate on a noisy battlefield. The Tuned Electromagnetic Resonance Collar -- or TERC sensor -- detects changes in the electrical field around the neck produced ... > more -
Interventional Neuroradiologists Treat Brain Strokes with New Kind of Stent
A new "wingspan" stent helps restore blood flow for patients with intracranial atherosclerotic disease, or ICAD. Surgeons insert the stent up the leg arteries, guide it to the brain, then let its ... > more -
Cardiologists Use Medical Physics to Pinpoint Cause of Chest Pains
Unless a patient with chest pain is checked out right away, it can be difficult to diagnose a heart condition, as opposed to less life-threatening causes such as heartburn. A new stress test can spot ... > more -
Computer Science Analyszes And Predicts Crime
Engineers at the University of Virginia have developed a new program, called web-cat, that allows police to easily access crime data online -- and spot trends that show what types of crimes happen ... > more
