An experimental cell phone works by absorbing and reflecting radio waves—meaning it's incredibly energy efficient and needs no battery. Christopher Intagliata reports.

Optical computers may have finally found a use—improving artificial intelligence

Quantum bits, aka qubits, can simultaneously encode 0 and 1. But multicolored photons could enable even more states to exist at the same time, ramping up computing power. Christopher Intagliata reports.

Researchers designed an antireflective coating for smartphone screens, with inspiration from the bumpy eyes of moths. Christopher Intagliata reports.

Increased testing of quantum computing techniques will open the door to solving new kinds of problems

The device will use artificial neurons and synapses to improve self-driving vehicle and drone performance 

Researchers built silver–zinc batteries that can bend and stretch—meaning they could be more elegantly integrated into future wearable devices. Christopher Intagliata reports. 

The breakthrough could lead to better data-storage devices and quantum computers

If flexible smartphones, e-paper and a new generation of smart watches are to succeed, we’ll need to invent something new
