Acoustic Waves Could Help Put Out Flames in Zero-Gravity Environments
Aboard NASA's "Weightless Wonder" airplane, physicists are experimenting with combustion and fluid flows in zero-g and developing a fire extinguishing system based on sound waves. The technique could ... > more -
Atmospheric Scientists Link Lightning to Ice Particles In Clouds
Satellite imaging is now helping atmospheric scientists link the amount of charged ice in clouds to lightning activity. Ice particles in thunderstorms can help increase precipitation, the scientists ... > more -
Stents Help Cardiothoracic Surgeons Treat Aortic Aneurysms
A new, minimally invasive procedure allows cardiothoracic surgeons to treat aortic aneurysm patients for whom open-chest surgery would pose serious risks. A stent endograft, inserted endoscopically ... > more -
EMG Helps Physiatrists Find Causes of Pain
Electromyography (EMG) detects the electrical potential generated by muscle cells, and can test nerve function. EMG can help physiatrists pin down the cause of back pain in cases such as spinal ... > more -
Pressure Sensors and Transducers Help Make Dummies More Life-Like
Electrical, computer, and biological engineering combine in creating baby-patient simulators for training new pediatricians. A new simulator incorporates microelectromechanical systems (MEMs) and ... > more -
With New Antibiotics, Pediatricians Fight Proxy War on Bugs
Strep throat has become harder to fight using penicillin or amoxicillin, but that's not because the Streptococci have developed a resistance to those drugs. Instead, more than 50 percent of children ... > more -
Structural Engineers Develop Disaster-Resistant Technology
A new bridge design replaces reinforced concrete columns and bars with steel tubes filled with concrete. The steel and concrete bind, creating strong yet supple columns For the bridge pier's footing, ... > more -
Portable Machines Go Beyond Prenatal Uses
Ultrasound uses sound waves that bounce off body parts, producing echoes. A computer translates the echoes into images that rival the quality of CAT scans and MRIs, showing broken bones, muscle ... > more -
Automotive Engineers Team Up to Improve Energy-Saving Technology
Mechanical and electrical engineers at DaimlerChrysler, General Motors and BMW have jointly developed a hybrid-vehicle technology that shuts the internal combustion engine off when the vehicle stops. ... > more -
Pavement Markings Make Drivers Feel They Are Going Too Fast
Engineers have developed new pavement markings that give drivers the illusion that the car is moving faster than it really is. The markings, called optical speed bars, are series of lines painted at ... > more
