When a new undersea communications cable becomes operational late this year, it will break the record for a key metric: data rate times distance. In a single second, its six fiber-optic pairs, stretching roughly 13,000 kilometers (8,000 miles) between Hong Kong and Los Angeles, will be able to send some 144 terabits in both directions. That’s as much data as you’d find in several hundred Blu-ray discs. The cable’s main purpose is to connect Facebook and Google data centers in East Asia with those in the United States.

For Better or Worse, Tesla Bot Is Exactly What We Expected

Tesla fails to show anything uniquely impressive with its new humanoid robot prototype

Elon Musk unveiled the Optimus humanoid robot at Tesla's AI Day 2022.

Tesla

At the end of Tesla’s 2021 AI Day last August, Elon Musk introduced a concept for “Tesla Bot,” an electromechanically-actuated, autonomous bipedal “general purpose” humanoid robot. Musk suggested that a prototype of Tesla Bot (also called “Optimus”) would be complete within the next year. After a lot of hype, a prototype of Tesla Bot was indeed unveiled last night at Tesla’s 2022 AI Day. And as it turns out, the hype was just that—hype.

While there’s absolutely nothing wrong with the humanoid robot that Musk very briefly demonstrated on stage, there’s nothing uniquely right, either. We were hoping for (if not necessarily expecting) more from Tesla. And while the robot isn’t exactly a disappointment, there’s very little to suggest that it disrupts robotics the way that SpaceX did for rockets or Tesla did for electric cars.

You can watch the entire 3+ hour livestream archived on YouTube here (which also includes car stuff and whatnot), but we’re just going to focus on the most interesting bits about Tesla Bot/Optimus.

"Nothing About Us Without Us"

Assistive technologies are often designed without involving the people these technologies are supposed to help. That needs to change.

Before we redesigned our website a couple of years ago, we took pains to have some users show us how they navigate our content or complete specific tasks like leaving a comment or listening to a podcast. We queried them about what they liked or didn’t like about how our content is presented. And we took onboard their experiences and designed a site and a magazine based on that feedback.

So when I read this month’s cover story by Britt Young about using a variety of high- and low-tech prosthetic hands, I was surprised to learn that much bionic-hand development is conducted without taking the lived experience of people who use artificial hands into account.

Government’s Role in Further Developing 5G Technologies and Future Networks

Learn about the impact of federally funded research on national security and the overall economy

Anritsu

Similar to 5G, many key technology developments have been supported by government funding and institutions for years. Federally Funded Research and Development Centers (FFRDC) and University Affiliated Research Centers (UARC) have been foundational elements of this government support.

This webinar will examine the impact this research has had on national security and the overall economy. It will also discuss how these institutions have made use of testing to attain these security and economic goals. Finally, it will look at how these resources can continue to be leveraged in the further development of 5G technologies and beyond for future networks.
