A United Nations group set out to clean up a Port-au-Prince neighborhood by converting trash to cooking fuel. It was a project with many goals, that ultimately wasn't sustainable financially. It seems many programs in Haiti suffer under their own weight.
Apple made waves with its iPhone 5 unveiling Wednesday — but perhaps not the waves it has at some of its previous launches. Are expectations too high for Apple, or is the company just not delivering like it used to? And, really, does it even matter?
Researchers at Vanderbilt University have discovered that we can harness a natural process -- photosynthesis -- to improve the effectiveness of solar collectors. By using a protein found in plants, electrodes can be made to convert more sunlight into energy.
About a quarter of all people worldwide live without electricity. For them, evenings and nights are spent by candlelight or kerosene lamp. But a group of scientists in Sri Lanka say they have found a creative way to bring simple electric lighting to rural households.
In 2010, Katherine Losse moved to a small town in western Texas after quitting her job at Facebook. As she reveals in her new memoir, "The Boy Kings," Losse had grown disillusioned with Silicon Valley's "programmed" culture and needed to unplug. In doing so, she found new meaning in the technology-driven world she left behind.
Bobak Ferdowsi is young, good looking and sports a stars-and-stripes Mohawk. He's also the flight director for NASA's Mars Curiosity rover. That Ferdowki doesn't look like your typical rocket scientist is what made him an overnight Internet sensation, and the new face of the U.S. space program.
A trio of Slovenians are taking an interest in cyber-security and turning it into art. They're asking people to submit their online passwords to a database they make publicly available. Eventually, they hope to turn it into a real-world exhibit.
This year's winner of the Google Science Fair is Brittany Wenger, a 17-year-old high school student from Florida. For her award-winning project, Wenger used her knowledge of computer science and biology to design an app to help doctors diagnose breast cancer.
An Arizona-based company, Hydronalix, has created a robotic flotation device named Emily that could provide assistance to lifeguards and help save lives.
In the Atacama Desert, there's a massive complex of highly sophisticated telescopes. But that's not enough. A group of European countries are planning to build a new, massive telescope nearby.
