Self-Cooling Soda Bottles?

Every day, the sun bathes the planet in energy--free of charge--yet few systems can take advantage of that source for both heating and cooling. Now, researchers are making progress on a thin-film technology that adheres both solar cells and heat pumps onto surfaces, ultimately turning walls, windows, and maybe even soda bottles into climate control systems.

Method to Better Predict Software Vulnerabilities

Researchers have developed a model to predict with much greater accuracy the number and severity of vulnerabilities that will likely surface in operating systems and in major software applications in the near future. The research is lead by Yashwant K. Malaiya, professor in the Department of Computer Science in Colorado State's College of Natural Sciences.

Stealth Radar System Sees Through Trees, Wall - Undetected

Engineers have invented a radar system that is virtually undetectable, because its signal resembles random noise. The radar could have applications in law enforcement, the military, and disaster rescue. With further development the technology could even be used for medical imaging.

Electronic Stability Control Could Prevent Nearly One-Third of All Fatal Crashes

A new study from the Insurance Institute for Highway Safety finds that as many as 10,000 fatal automobile crashes could be prevented if all vehicles were equipped with electronic stability control or ESC.
