In fact, the Space Force’s 45th Weather Squadron predicts 95% odds of “go for launch” weather conditions.

SpaceX announced the Starlink 6–43 launch is targeted for 7:05 p.m. EDT Sunday from Launch Complex 40, with backup opportunities available if needed until 11:03 p.m.

The Falcon 9 rocket will deploy another payload of 23 Starlink broadband satellites into low-Earth orbit, adding to SpaceX’s growing constellation.

A team of researchers at Cornell University has created a semiconductor chip that will allow ever-tinier devices to function at the higher frequencies required for the next generation of 6G communication technology.

In addition to requiring more bandwidth at higher frequencies, the next generation of wireless communication also demands more time. According to researchers, the new semiconductor provides the appropriate time delay to prevent signals from dissolving at a single point in space after being relayed over numerous arrays.

A team of Stony Brook University physicists and their collaborators have taken a significant step toward the building of a quantum internet testbed by demonstrating a foundational quantum network measurement that employs room-temperature quantum memories. Their findings are described in a paper published in the Nature journal Quantum Information.

Research with quantum computing and quantum networks is taking place around the world in the hopes of developing a quantum internet, a network of quantum computers, sensors, and communication devices that will create, process, and transmit quantum states and entanglement. It is anticipated to enhance society’s internet system and provide certain services and securities that the current internet does not have.

The field of quantum information combines aspects of physics, mathematics, and classical computing to use quantum mechanics to solve complex problems much faster than classical computing and to transmit information in an unhackable manner. While the vision of a quantum internet system is growing and the field has seen a surge in interest from researchers and the public at large, accompanied by a steep increase in the capital invested, an actual quantum internet prototype has not been built.

The next generation of wireless communication not only requires greater bandwidth at higher frequencies – it also needs a little extra time.

Cornell researchers have developed a semiconductor chip that adds a necessary time delay so signals sent across multiple arrays can align at a single point in space, and without disintegrating. The approach will enable ever-smaller devices to operate at the higher frequencies needed for future 6G communication technology.

After the advent of 5G, engineers have been trying to devise techniques to further enhance wireless communication technology. To increase these systems’ data transmission rate, they will ultimately need to extend their carrier frequency beyond 100 gigahertz, reaching the terahertz range.

Existing devices and technologies, however, have proved to be unable to achieve such high carrier frequencies. One proposed solution to reach this goal entails the use of some quantum materials that exhibit the so-called non-linear Hall effect.

Researchers at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) e. V. and University of Salerno have identified a promising material for the development of next generation wireless communication systems, namely thin film elemental bismuth. Their paper, published in Nature Electronics, shows that this material exhibits a room-temperature nonlinear Hall effect.

Underlying the storm of hype and funding in the AI sector right now is a scarce resource: data, created by old-fashioned humans, that’s needed to train the huge models like ChatGPT and DALL-E that generate text and imagery.

That demand is causing all sorts of drama, from lawsuits by authors and news organizations that say their work was used by AI companies without their permission to the looming question of what happens when the internet fills up with AI-generated content and AI creators are forced to use that to train future AI.

And, of course, it’s also fueling new business deals as AI developers rush to lock down repositories of human-generated work that they can use to train their AI systems. Look no further than this wild scoop from Bloomberg: that an undisclosed AI outfit has struck a deal to pay Reddit $60 million per year for access to its huge database of users’ posts — perhaps the surest sign yet that user data is the key commodity in the AI gold rush.

New phased-array transmitter design overcomes common problems of CMOS technology in the 300 GHz band, as reported by scientists from Tokyo Tech. Thanks to its remarkable area efficiency, low power consumption, and high data rate, the proposed transmitter could pave the way to many technological applications in the 300 GHz band, including body and cell monitoring, radar, 6G wireless communications, and terahertz sensors.

Today, most frequencies above the 250 GHz mark remain unallocated.

Accordingly, many researchers are developing 300 GHz transmitters/receivers to capitalize on the low atmospheric absorption at these frequencies, as well as the potential for extremely high data rates that comes with it.

An analysis of DOIs suggests that digital preservation is not keeping up with burgeoning scholarly knowledge.

SpaceX says it’s made progress to drive down Starlink’s latency by over 30% for US subscribers, citing improvements implemented over the past month.

On Friday, the company published a report that sheds light on SpaceX’s ongoing effort to one day bring the latency rates down to under 20 milliseconds.

“In the United States alone, we reduced median latency by more than 30%, from 48.5ms to 33ms during hours of peak usage,” the company wrote. “Worst-case peak hour latency (p99) has dropped by over 60%, from over 150ms to less than 65ms.”
