For the first time, scientists have successfully grown vocal cords in the lab, with tests showing the engineered tissue to be functional, with the ability to transmit sound. While the research is just the first step on a long path towards clinical use, the results are very promising, providing a solid basis for future study.
Amplifying light a few hundred times with magnifying lenses is easy.
Amplifying light by altering the resonant properties of light itself is a much
more difficult proposition. However, if recent research by engineers at the
University of Wisconsin-Madison engineers is anything to go by, the effort is
well worth it: They claim to have constructed a nanoscale device that can emit
light as powerfully as an object more than 10,000 times its size.
Cars are one of mankind's most revolutionary creations. But just like with the iPhone, space travel or Wi-Fi, there's always room for improvement. In the eyes of a team of University of Wisconsin-Madison engineers, one of the more promising ways automotive technology might be improved upon lies in the energy wastage caused by friction as tires roll across the road. Armed with special nanogenerator and a toy Jeep, the researchers have demonstrated that this power can be captured and turned into electricity, a development that could bring about better fuel efficiency in the full-sized cars of the future.
As electronic devices are becoming outdated at an increasingly fast pace, e-waste continues to be a huge problem.
That's why scientists from the University of Wisconsin-Madison have
started producing "wooden" semiconductor chips that could almost
entirely biodegrade once left in a landfill. As an added bonus, the
chips are also flexible, making them prime candidates for use in
