- Towards low-cost LED lighting
- You all know that incandescent bulbs are pretty inefficient, converting only 10% of electricity into light -- and 90% into heat. Light-emitting diodes, or LEDs, could soon replace incandescent and compact fluorescent bulbs in our homes. They are more efficient and environmentally friendly. But LED lights are currently too expensive...

- A refrigerator inside your laptop?
- Even if the semiconductor industry is working on it, computer chips are big energy spenders. And new cooling systems will be needed in the future. Purdue University engineers think they have a solution. They've developed a miniature refrigeration system small enough to fit inside laptops. Unlike conventional cooling systems, which...

- Cellphones to detect dirty bombs?
- Purdue University engineers are developing a system which would use a U.S. network of cellphones to detect dirty bombs and nuclear weapons. They say that 'such a system could blanket the nation with millions of cellphones equipped with radiation sensors able to detect even light residues of radioactive material.' They...

- Simulating planes flying at Mach 6
- Scramjets, or supersonic combustion ramjets, such as the X-51A aircraft being built by Pratt & Whitney and Boeing, should start to fly in 2009. And if everything goes according to plan, missiles flying at Mach 6 could be deployed by 2015. But designing such planes is not so easy. This...

- Anatomy of a virus
- No, I'm not talking about a computer virus here, but about a real one, the Epsilon 15, which attacks the bacterium Salmonella. By writing a few lines of computer code, biologists from Purdue University have found a way to control a high-resolution microscope. This led them to look inside a...

- Saving energy in office buildings
- Precooling a structure in the morning before temperature rises has been done before. It later saves energy during times of peak demand and you might even have done it intuitively at home. But now, engineers from Purdue University have developed a 'control' algorithm which promises to reduce energy consumption --...

- Better 'robot manipulators'
- According to this news release from Purdue University, civil engineers, who deal with statics, and mechanical engineers, who deal with kinematics, have unified their efforts to create dual theorems which combine the mathematics of both kinematics and statics. In other words, they've shown that these concepts are in fact analogous....

- Extreme weather changes in front of us
- Researchers from Purdue University have used their supercomputers to run the largest simulation of what could become the weather in the U.S. between 2071 and 2095. And their model, which was validated by using data from last century, predicts "more extreme temperatures throughout the country and more extreme precipitation along...

- Searching in 3-D
- Eighteen months ago, I was writing that shape searching could become a reality. Now, the researchers at Purdue University who developed this initial system are providing benchmarking tools to evaluate how well their search system is working. Even if these tools are designed for computer-aided design CAD engineers, you're welcome...
