Researchers from Osaka University and IMRA AMERICA use a stimulated Brillouin scattering laser to generate the signals needed by sub-terahertz transmitters and receivers, enabling super-high communication speeds for our tablets and phones.

Researchers demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.

Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years old.

A quasar is a compact region powered by a supermassive black hole located in the center of a massive galaxy.

They are extremely luminous, with a point-like appearance similar to stars, and are extremely distant from Earth...

American Amber Pearson used to wash her hands until they bled, terrified by the idea of contamination from everyday items, a debilitating result of her obsessive compulsive disorder (OCD).

But the repetitive rituals of her condition are largely consigned to memory, thanks to a revolutionary brain implant that is being used to treat both her epilepsy and her OCD.

“I’m actually present in my daily life and that’s incredible,” the 34-year-old told AFP.

“Before, I was just constantly in my head worrying about my compulsions.”

Brain implants have hit the headlines recently with Elon Musk’s announcement that his Neuralink company had placed a chip in a pat...

There has been significant progress in the field of quantum computing.

Big global players, such as Google and IBM, are already offering cloud-based quantum com...
