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 -

Biological Engineers Generate Natural Gas with Bacteria
A new kind of waste digester uses two different strains of bacteria in different tanks. This would normally take place in the same environment, but microbiologists have now separated it into two ... > more -
Engineering Students Build Next-Generation Bathyscaphe
Computer, electrical, and mechanical engineering students at the University of Florida have built a fully automated underwater vehicle. Driven by five thrusters and controlled by complex electronics, ... > more -
Engineers Devise Implantable Dosimeter to Track Success of Radiation Therapy
Radiologists could soon measure the amount of radiation exposure experienced by different tissues using an implantable capsule. The device contains a small dosimeter and sends radiation exposure data ... > more -
Human-Factors Engineers Focus on User-Friendliness
Human-factors engineers -- whose training includes psychology -- specialize in testing products for usability, for example checking whether a copying machine's legs get in the way, or measuring how ... > more -

Engineers Test Ventilated Seats And Thermal-Acoustic System To Make A/C Energy-Efficient
Engineers at a national lab have shown that small fans embedded in car seats could help cool passengers down -- saving up to 7 percent of the 30 to 40 gallons of gasoline per year an average driver ... > more -
Robotic Camera Will Take Motion X-Rays by Following Patients' Movements
Orthopedic injuries are among the most common reasons people visit the doctor. Whether it's pain in the knee, hip or shoulder, doctors have a difficult time making an exact diagnosis without surgery. ... > more -
Physical Chemists Develop New High-Capacity Storage Technology
Holograms allow permanent optical data storage and retrieval with far higher densities than CDs or DVDs, using the interference patterns of two lasers. Physical chemists are now developing the ... > more
