Engineer devises ways to improve gas mileage
Last summer, it was very expensive to fill up a gas tank when the gasoline price hit close to four dollars a gallon. Transportation by road or air consumes fuel, which not only increases our vulnerability to foreign imports but also is a source of greenhouse gas emissions that will impact adverse change in climate and global warming.
Shifting sound to light may lead to better computer chips
By reversing a process that converts electrical signals into sounds heard out of a cell phone, researchers may have a new tool to enhance the way computer chips, LEDs and transistors are built.
UB engineers prove that carbon nanotubes are superior to metals for electronics
In the quest to pack ever-smaller electronic devices more densely with integrated circuits, nanotechnology researchers keep running up against some unpleasant truths: higher current density induces electromigration and thermomigration, phenomena that damage metal conductors and produce heat, which leads to premature failure of devices.
Researchers develop flow sensors based on blind fish hair structures
A blind fish that has evolved a unique technique for sensing motion may inspire a new generation of sensors that perform better than current active sonar.
Hollow gold nanospheres show promise for biomedical and other applications
A new metal nanostructure developed by researchers at the University of California, Santa Cruz, has already shown promise in cancer therapy studies and could be used for chemical and biological sensors and other applications as well.
New theory on largest known mass extinction in the history of the Earth
The largest mass extinction in the history of the earth could have been triggered off by giant salt lakes, whose emissions of halogenated gases changed the atmospheric composition so dramatically that vegetation was irretrievably damaged.
Maybe robots dream of electric sheep, but can they do science?
Using the digital mind that guides their self-repairing robot, researchers at Cornell University have created a computer program that uses raw observational data to tease out fundamental physical laws. The breakthrough may aid the discovery of new scientific truths, particularly for biological systems, that have until now eluded detection.
MIT virus battery could power cars, electronic devices
For the first time, MIT researchers have shown they can genetically engineer viruses to build both the positively and negatively charged ends of a lithium-ion battery.
New storage system design brings hydrogen cars closer to reality
Researchers have developed a critical part of a hydrogen storage system for cars that makes it possible to fill up a vehicle's fuel tank within five minutes with enough hydrogen to drive 300 miles.
Researchers find better way to manufacture fast computer chips
Engineers at Ohio State University are developing a technique for mass producing computer chips made from the same material found in pencils.

Humanoid robot helps scientists to understand intelligence
A humanoid robot newly acquired by Imperial College London will lead to a deeper understanding of human intelligence, says scientists.
3-d printing hits rock-bottom prices with homemade ceramics mix
This story is, literally, stone age meets digital age: University of Washington researchers are combining the ancient art of ceramics and the new technology of 3-D printing. Along the way, they are making 3-D printing dramatically cheaper.
Surveillance vehicles take flight using alternative energy
Nearly undetectable from the ground, unmanned aerial vehicles (UAVs) are widely used by the military to scan terrain for possible threats and intelligence. Now, fuel cell powered UAVs are taking flight as an Office of Naval Research (ONR)-sponsored program to help tactical decision-makers gather critical information more efficiently... and more quietly.
Quantum computers will require complex software to manage errors
Highlighting another challenge to the development of quantum computers, theorists at the National Institute of Standards and Technology (NIST) have shown that a type of software operation, proposed as a solution to fundamental problems with the computers' hardware, will not function as some designers had hoped.
Ancient diatoms lead to new technology for solar energy
Engineers at Oregon State University have discovered a way to use an ancient life form to create one of the newest technologies for solar energy, in systems that may be surprisingly simple to build compared to existing silicon-based solar cells.
New flat flexible speakers might even help you catch planes & trains
A groundbreaking new loudspeaker, less than 0.25mm thick, has been developed by University of Warwick engineers, it's flat, flexible, could be hung on a wall like a picture, and its particular method of sound generation could make public announcements in places like passenger terminals clearer, crisper, and easier to hear.
Putting the squeeze on an old material could lead to 'instant on' electronic memory
The technology of storing electronic information - from old cassette tapes to shiny laptop computers - has been a major force in the electronics industry for decades.
New technique provides illusion of restoration without risk of damage to priceless artifacts
Museum patrons can now see artifacts as they were originally created through a restoration process that poses no risk of damage to the priceless objects.
DNA tricked to act as nano-building blocks
McGill researchers have succeeded in finding a new way to manufacture nanotubes, one of the important building blocks of the nanotechnology of the future.
New technique that scrambles light may lead to sharper images, wider views
When photographers zoom in on an object to see it better, they lose the wide-angle perspective -- they are forced to trade off "big picture" context for detail. But now an imaging method developed by Princeton researchers could lead to lenses that show all parts of the scene at once in the same high detail. The new method could help build more powerful microscopes and other optical devices.

| Quotes | Ive always wanted to be a scientist. That way, I could get a bunch of grants and do research into whether money can really buy happiness.
Kyannke.
Ive always wanted to be somebody, but I see now I should have been more specific.
