Scientist Dickson Despommier has designed a scheme to grow crops inside 30-story skyscrapers. This urban farm concept could help feed a rapidly growing population, leave space for forests, and supply potable water for entire cities. read more »
It sounds too good to be true: a machine that can get rid of almost any kind of waste at a fraction of the cost of today's disposal techniques, eliminate existing landfills, and produce an excess of clean energy to be sold back to the grid. This very realistic process is called plasma gasification. read more »
For some people, taking high-quality pictures is the main feature they'd use on their cell phone (after talking, of course). Sony Ericsson's new K770 Cyber-shot phone may offer the best in this category so far. read more »

ConocoPhillips and Tyson Foods, the two companies partnering in initiative, say fat from pigs, cows, and chickens will offer a cleaner fuel and provide about 3% of ConocoPhillips' diesel requirements. Critics have fears over animal rights, food supply, ethics, and environmental benefits. read more »
Kameraflage is a new type of display technology that takes advantage of digital cameras' ability to see a broader spectrum of light than the human eye. Objects, designs, words, and pictures that are invisible in the real world may be viewed with a digital camera equipped with kameraflage. read more »
By using buoys to capture energy from the ocean's waves, researchers are developing an alternative energy technology that researchers say could provide 10% of the required power for the US. read more »
In the Human Salivary Proteome Project, researchers are developing saliva tests that will take the place of routine blood tests and even do more, such as detect cancer at early stages. The researchers predict that saliva tests will replace needle pricks and detect multiple types of cancer by 2011. read more »
Scientists have discovered a method for making instant steam without electricity. Instant steam could have many applications, including killing superbugs such as staph infections, providing mobile power generation and powering rockets and cars. But it's first application? Cleaning gum from sidewalks. read more »
These new space suits designed by MIT scientist Dava Newman aren't just cool-looking, they're also the state of the art in mobility and protection for astronauts of the future. read more »
Two teenagers from Ontario have built an electric vehicle modeled after a motorcycle, but with one major difference: there's no hand steering controls. Instead, the rider leans in the direction of desired motion, like a Segway, but with the coolness of a sports bike.
It's water-resistant, solar-powered, energy-efficient and kid-friendly-the One Laptop Per Child project may finally be turning into reality. read more »
Some have called the idea outlandish. A better word seems to be insane. And yet, Dynamic Architecture, a company in Dubai in the United Arab Emirates, is marching ahead with their plans for a skyscraper powered by wind turbines. read more »
By coating fabrics with a nano-thin layer of chemicals, researchers have found a simple and unobtrusive way to kill germs and viruses without harming humans. The start-up company claims that the chemicals should be able to kill any type of germ, from the common cold and the flu, to strep and staph infections, and even SARS.
Electroconvulsive therapy (ECT) may become a thing of the past when researchers can fine-tune a new technique called deep brain stimulation. Depression and other mental conditions, such as Parkinson's, may be treated by pinpointing the exact neuron responsible for the ailment. Besides repair, the technology could also likely take things a step further in tomorrow's brave new world, and enhance cognitive abilities such as memory and alertness. read more »
There are some inventions that help improve the lives of some people, and then there are the inventions-sometimes the simplest kind-that revolutionize the lives of billions of people. Abul Hussam's water filter, for instance, is providing clean water for entire countries of people suffering from arsenic poisoning, a toxic chemical in dirty water.
A man from Columbus, Ohio spent more than 20 years tinkering with an idea scorned by professionals: a car that uses water for fuel. After making progress, and declining billion-dollar offers for giving up, the eccentric inventor died after a celebratory sip of cranberry juice with two investors who haven't been heard from since. Here's his story... read more »
This ultra-low-flying plane uses a special lift technique known as "wing-in-ground" (WIG) to reduce drag. More than an impressive feat of engineering, these planes are also faster and more efficient than their counterparts in the clouds. read more »
Researchers from Japan have discovered an antibiotic that could enable cancer patients to keep up to 70% of their hair while undergoing chemotherapy. read more »
In an effort to keep minimally processed vegetables fresher for longer, companies are collaborating in a new project to design super fresh packaging. Among the preservation techniques is one that many three-year-olds are sure to enjoy: edible packaging. read more »
