- Toward more efficient fuel cells?
- A very short report from the American Association for the Advancement of Science AAAS, 'A cool fuel cell,' says that Spanish researchers have developed a new way to operate solid oxide fuel cells, which could potentially provide electricity on an industrial scale, at near room temperature. This new super-lattice material...

- First paper-based transistors
- Portuguese researchers have created the first paper-based transistors. To be more precise, they've made the first field effect transistors FET with a paper interstrate layer. According to the research team, these new transistors offer the same level of performance as 'state-of-the-art oxide based thin film transistors TFTs produced on glass...

- Your flat screen TV could be killing the planet, read all about it
- There's a research paper being much-touted in the tech and green press: concludes that nitrogen trifluoride is many times worse for the earth's atmosphere than methane or CO2 or the more popular greenhouse gases. That nitrogen trifluoride, also known as NF3, its chemical formula, is used in making...you got...

- IBM to cool chips with H20
- Much like a Porsche boxer engine -- only much, much smaller -- scientists from the IBM Zurich Research Lab and the Fraunhofer Institute in Berlin are working on a microchip that uses micro pipes of water to cool itself, IBM announced this morning. The chip's components are...

- Microwaves from silicon chips?
- X-rays are widely used for medical imaging and security, but they still are dangerous. Would it be possible to replace X-rays by an imaging technology based on microwave radiation? Until now, it was not feasible because portable devices were not powerful enough. Now, two U.S. scientists have found how to...

- Self-healing ceramics for nuclear safety
- Pacific Northwest National Laboratory PNNL researchers have used supercomputers to simulate how common ceramics could repair themselves after radiation-induced damages. This is an important discovery because 'materials that can resist radiation damage are needed to expand the use of nuclear energy.' These ceramics, which are able to handle high-radiation doses,...

- Checking the clock for DST is a good reminder for tech product expiration dates
- Various groups use the twice-yearly daylight savings time shift as a reminder to check product expiration dates. While most are about things we eat, drink and apply to ourselves, there are a few items we might want to check in the technology department, including flash cards. My...

- Lasers for analyzing our breath?
- According to the Optical Society of America OSA, U.S. researchers have shown it is possible to use lasers to analyze our breath to detect diseases such as asthma or cancer. This technique -- hold your breath -- is called 'cavity-enhanced direct optical frequency comb spectroscopy.' It is based on research...

- A pharmacy in a nanotechnology-based thin film
- MIT researchers have developed a new implantable device to improve our health. This nanoscale thin-film coating can deliver controlled drug doses to specific targets, acting as a 'micro pharmacy' inside our bodies. It could be used to deliver drugs for cancer, epilepsy, diabetes and other diseases. This film, which is...

- Fly the green skies at Mach 5
- The European Union has launched in 2005 its Long-Term Advanced Propulsion Concepts and Technologies project LAPCAT. Several companies worked on this €7 million EU-funded project. For example, Popular Science reports that Reaction Engines Limited has designed an hydrogen-powered hypersonic airliner simply dubbed A2. This plane would fly at Mach 5...

- Cellphones to track air pollution
- Computer scientists in Cambridge, UK, are using bike couriers to monitor air pollution. These couriers are doing their usual jobs, but their bicycles are equipped with air-pollution sensors and GPS units that connect to their cellphones via Bluetooth. So their phones are constantly reporting the levels of carbon monoxide, nitrogen...

- Self-powered nanowires
- Many research teams around the world are building nanodevices of some kind. But these very small devices need very small sources of power to be fully functional. Now, researchers at the University of Illinois at Urbana-Champaign UIUC have shown that a single nanowire can produce power by harvesting mechanical energy...
