Researchers create cell phones for sign language

(PhysOrg.com) -- Cornell researchers and colleagues have created cell phones that allow deaf people to communicate in sign language, the same way hearing people use phones to talk.

Peugeot unveils petrol hybrid using compressed air

French carmaker PSA Peugeot Citroen unveiled Tuesday a petrol hybrid engine that stores energy using compressed air which it hopes will be a game-changing technology to improve energy efficiency.

Compressing photonic signals for greater bandwidth

Cornell researchers have developed an ingenious method to time-compress optical signals. The process could enable optical communication systems to carry many more bits per second or could also be used to generate short bursts ...

Compression experiments lead to shocking results

Using acceleration 1 trillion times faster than a jet fighter in a maximum turn, researchers have gained new insight into dynamic compression of aluminum at ultrahigh strain rates.

Study predicts bedrock weathering based on topography

Just below Earth's surface, beneath the roots and soil, is a hard, dense layer of bedrock that is the foundation for all life on land. Cracks and fissures within bedrock provide pathways for air and water, which chemically ...

Let's store solar and wind energy – by using compressed air

Electricity generated by fossil fuels is increasingly unsustainable and a shift towards renewable energy – principally from the sun and wind – is vital. Renewable generation is already less expensive per unit than its ...
