Turns out the key to making things lighter than air is…light! California scientists think they’ve found a way to make objects levitate using concentrated light — a theory that could even propel ...

A team of scientists says they've found a specific kind of light wave that can pierce directly through objects, making it seem as though they were totally invisible. This new approach, however, is a ...

3D printing has changed the way people approach hardware design, but most printers share a basic limitation: they essentially build objects layer by layer, generally from the bottom up. This new ...

Princeton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical ...

These days, the electronic components at the heart of devices like smartphones and computers are assembled by automated machines. A new study by an international team of researchers has established ...

Have we made an object that could travel at at least 1% the speed of light? – Anadi, age 14, Jammu and Kashmir, India Light is fast. In fact, it is the fastest thing that exists, and a law of the ...

Electrical and computer engineers have created a physical artificial neural network -- a device modeled on how the human brain works -- that can analyze large volumes of data and identify objects at ...

Specially designed materials enable objects of different sizes to be levitated and manipulated with light, thanks to new research. Researchers at Caltech have designed a way to levitate and propel ...

Once thought of as the province of only "Star Trek" or "Harry Potter," cloaking technologies could become a reality with a specially designed material that can mask itself from other forms of light ...
