We will soon need to make some difficult choices.

Given current trends, that number will be reached within a year or so. There are ways to mitigate the effect of these streaks. Painting the satellites and adding reflective panels could reduce their brightness, particularly at infrared wavelengths that are important for near-Earth asteroid detection.

But the study points out that the mitigation strategy currently proposed by Starlink won’t be sufficient to avoid an impact on astronomy.

It is clear we will soon need to make some difficult choices about satellite Internet. While it could broaden human connection to even the poorest and most remote regions of the world, it could also destroy our ability to view the heavens and more deeply understand the universe we call home.

Say goodbye to that buffering wheel.

The next generation of Wi-Fi is just around the corner.

Taiwan-based semiconductor firm MediaTek successfully conducted the first-ever live demo for Wi-Fi 7 technology, according to a report from DigitalTrends. The company also stated that it expects Wi-Fi 7 products to become available next year in anticipation of the launch of the next-gen Wi-Fi sometime around 2024.

In a press statement, the company said it showed off the “super-fast speeds and low latency transmission” of its Wi-Fi 7 Filogic technology to “key customers and industry collaborators.” Wi-Fi 7, as shown in MediaTek’s demo, will deliver 2.4 times more speed than Wi-Fi 6, even using the same number of antennas.

This, according to the Wi-Fi Alliance, means that Wi-Fi 7 could provide speeds of more than 30 gigabits per second (Gbps) and close to 40Gbps. As ArsTechnica points out, the still relatively new Wi-Fi 6 reaches speeds of up to 9.6Gbps.

A string of Chinese video platforms are accelerating moves toward producing high-quality, 8K ultrahigh definition content by integrating 5G, artificial intelligence and virtual reality technologies.

It’s an important step toward moving 8K video into people’s living rooms, experts said.

Chinese UHD video production and distribution platform Sikai Garden Network Technology Co Ltd, also known as 4K Garden, plans to send UHD content to different terminal devices, including televisions, outdoor 8K light-emitting diode screens and VR headsets, and to explore diversified and innovative applications for the UHD industry, said Wu Yi, chairman of 4K Garden.

“Your scientists were so preoccupied with whether they could, they didn’t stop to think if they should.” — Dr Ian Malcolm in Jurassic Park

Throughout most of human history, the goal was to establish a better life for people. Whether proponents of change admit to it or not, they hope to make everything perfect. However, this very impulse to improve security against everything bad and eliminate all physical ills could precipitate just another kind of doom.

To borrow the words of a Jeff Goldblum character, those of us who did the most to uplift humanity may have been “so preoccupied with whether they could, they didn’t stop to think if they should.”

In Carl Sagan’s The Demon-Haunted World, he pointed out that the modern world is complicated. Everything we don’t understand is something to fear (unless you are a specialist in it), and it is a thing that can be ignorantly speculated about in a vacuum, as vaccines are by many on social media.

Quantum computers aren’t quite ready for the home lab, but since there are ways to connect to some over the Internet, you can experiment with them more easily than you might think. [Norbert] decided to interface a giant quantum computer to an ordinary Arduino. Why? Well, that isn’t necessarily clear, but then again, why not? He explains basic quantum computing and shows his setup in the video below.

Using the IBM quantum computer and the open source Qiskit makes it relatively easy, with the Python code he’s using on the PC acting as a link between the Arduino and the IBM computer. Of course, you can also use simulation instead of using the real hardware, and for such a simple project it probably doesn’t matter.

ORLANDO, Fla., Jan. 6 (UPI) — SpaceX kicked off a surge in launch activity Thursday with the successful launch of 49 of the company’s Starlink communications satellites from Florida, heading south along the state’s coastline.

Five SpaceX missions may launch in the next month on the southern polar trajectory, flying closer to the Florida coast toward Miami than most launches, according to the U.S. Space Force.

The Falcon 9 rocket lifted off as planned at 4:49 p.m. EST from Complex 39A at Kennedy Space Center. Nine minutes after launch, the first-stage booster landed successfully on a barge in the Atlantic Ocean.

They claim that more than 100,000 passengers could be affected in a single day. 🤔

Several high-profile executives of U.S. airlines warned on Monday, January 17, of an oncoming “catastrophic” aviation crisis that will take hold by Wednesday should AT&T and Verizon activate their new 5G services, a report from Reuters reveals.

In a letter obtained by Reuters, the CEOs of several passenger and cargo airlines in the United States, including Delta, United, and Southwest Airlines, warned that signals from the two companies’ new C-Band 5G cell towers could interfere with navigation and safety equipment on their planes.
