A team of international scientists have developed an ultra-high speed signal processor that can analyze 400,000 real time video images concurrently, according to a paper published in Communications Engineering.

The team, led by Swinburne University of Technology’s Professor David Moss, have developed a processor that operates more than 10,000 times faster than typical electronic processors that operate in Gigabyte/s, at a record 17 Terabits/s (trillion bits per second).

The technology has profound implications for the safety and efficiency of driverless cars, medical imaging and could help find habitable planets beyond our solar system.

A system called Coscientist scours the Internet for instructions, then designs and executes experiments to synthesize molecules.

Google, the internet giant now a subsidiary of Alphabet, announced on Tuesday that it will limit the kinds of queries related to elections that its chatbot Bard and search generative experience can answer ahead of the 2024 U.S. Presidential election.

The company said that the new restrictions will be implemented by early 2024. The company recently made a landmark change to its location data privacy which has made it difficult for law enforcement agencies to access private location data of people near the crime scene and issue geofence warrants.

According to Reuters, the U.S. is not the only country that will witness crucial elections in 2024. India, the world’s largest democracy, and South Africa, among others, will also hold national elections in the same year.

Kuiper internet satellites will form a mesh network using optical links.

CAPE CANAVERAL, Fla. (AP) — An orange tabby cat named Taters stars in the first video transmitted by laser from deep space, stealing the show as he chases a red laser light.

The 15-second video was beamed to Earth from NASA’s Psyche spacecraft, 19 million miles (30 million kilometers) away. It took less than two minutes for the ultra high-definition video to reach Caltech’s Palomar Observatory, sent at the test system’s maximum rate of 267 megabits per second.

The video was loaded into Psyche’s laser communication experiment before the spacecraft blasted off to a rare metal asteroid in October. The mission team at NASA’s Jet Propulsion Laboratory in Pasadena, California, decided to feature an employee’s 3-year-old playful kitty.

Watch live coverage as SpaceX launches a Falcon 9 rocket with 23 second-generation Starlink internet satellites. Liftoff from pad 40 at Cape Canaveral Space Force Station is scheduled for tonight at 11:01 p.m. EST (0401 UTC). The first-stage booster, making its third flight, will land on the drone ship ‘A Shortfall of Gravitas’ about eight and a half minutes into the flight.\

Our live coverage from Cape Canaveral, with commentary by Will Robinson-Smith, will begin about an hour before launch.\

DARPA has tapped Raytheon to design and develop a wireless, airborne relay system to “deliver energy into contested environments,” as part of its Energy Web Dominance program, in which DARPA wants to be able to power anything from nearly anywhere.

Under a two-year, US$10 million DARPA contract, Raytheon will create a Persistent Optical Wireless Energy Relay (POWER) system, using a series of high altitude unmanned aircraft equipped with laser-based power receiving and transmitting capabilities. Energy will be beamed up to high altitude, then relayed across however many jumps are necessary to reach the target area.

That target might be on the ground, or it might itself be another autonomous aerial platform, in which case it could stay airborne as long as necessary, its batteries being constantly charged from afar.

By combining photonic and electronic components, scientists have built a prototype communications chip that can effectively access high enough radio frequency bandwidths for uses including advanced radar as well as 6G and 7G.

Researchers call it the ‘Holy Grail’ for physicists and engineers.

A group of researchers, led by Professor Chan Chi-hou from the City University of Hong Kong, created a special antenna that can control all five important aspects of electromagnetic waves using computer software.

The antenna, which they have named ’microwave universal metasurface antenna,’ is capable of dynamically, simultaneously, independently, and precisely manipulating all the essential properties of electromagnetic waves through software control.
