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

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

Weather System Protects Homeland Security
Homeland security officials
are tapping researchers'
capability to predict the
paths of toxic waste spills
and hazardous airborne
particles. Using computer

Detecting Deadly Chemicals
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

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 -
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 -
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 -
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 -
Electrical Engineering Student Designs Early-Warning System for Harmful Gases
Respirators save lives for the first responders who wear them, but their cartridges need to be changed often. Without knowing it, users could be inhaling deadly gases. Electrical engineering student ... > 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 -
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 -
Entomologists Train Insects to Act Like Sniffing Dogs
If rewarded with sugary water, wasps can be trained in minutes to follow specific smells. The olfactory sensors in their antennae can sense chemicals in the air in concentrations as tiny as a few ... > more -
Doppler-based Stethoscope Ignores Outside Sounds
A new ultrasound stethoscope ignores outside noise, allowing medics to hear life-saving sounds inside the body. Developed by electrical engineers, the device exploits the Doppler effect as it sends ... > more
