Research opens doors in photonic quantum information processing, optical signal processing and microwave photonics. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new integrated photonics platform that can store light and electrically control its frequency (or color) in an integrated circuit.

The platform draws inspiration from atomic systems and could have a wide range of applications including photonic quantum information processing, optical signal processing, and microwave photonics...

Call it clever, brand it a cheater, but don’t feel ashamed to find it terribly interesting. The “it” is CycleGAN, and its link to steganography—where messages and information are hidden within nonsecret text or data. So, in 2019 it cannot be that shocking for people to learn that a machine, not a human, can cheat its way though a task. The AI in this instance, like good human spies and cons, learned when to hide some information that can be used later.

In Packt, Bhagyashree R wrote that “The researchers discovered the machine was encoding data of the aerial map into the noise patterns of the street map on the down low...

New research demonstrates a new optogenetics method that eliminates the need for bulky optical fibers, gives researchers more precise control of the light’s intensity, and allows for stimulating multiple areas of the brain simultaneously. Optogenetics is a biological technique that uses light to turn specific neuron groups in the brain on or off. For example, researchers might use optogenetic stimulation to restore movement in case of paralysis or, in the future, to turn off the areas of the brain or spine that cause pain.

“We’re making these tools to understand how different parts of the brain work,” Gutruf said...
