However, traditional atomic clocks are bulky, exhibit frequent instabilities due to various environmental factors, and require calibration. Due to these limitations, technological advancements and the miniaturization of atomic clocks are ongoing to make them more accessible and practical for various applications.
Four individuals have agreed to be sequestered inside a 1,700-square-foot simulated Mars habitat at NASA’s Johnson Space Center to study what it would be like to live on the Red Planet and how humans can learn to cope in that extreme environment.
During their 378-day stay, which officially kicked off earlier this week, they’ll have a surprisingly busy schedule, including a strict exercise regimen as well as a lengthy list of duties, from performing simulated spacewalks to growing crops.
In other words, it’s a demanding job that’s bound to be tough on the crew of four.
VIDEO : Masahiko Inami and his team at the University of Tokyo have created a wearable — and exchangeable — multi-armed device to explore the social interaction between multiple users of the robotic limbs. The bot has six sockets that can hold fingers, arms or a claw.
Apple’s next version of the AirPods Pro equipped with USB-C will ship this fall, a report claims, and it may even help users discover hearing problems too.
Apple is rumored to be working on an updated version of the AirPods Pro that could arrive within months. That model is already believed to be using USB-C for its wireless charging case instead of Lightning, but it is thought that it could finally land this fall.
According to Mark Gurman’s “Power On” newsletter for Bloomberg, the AirPods Pro 2 is set to launch in the fall at the same time as the iPhone 15.
Tesla was able to produce almost 480,000 cars and deliver more than 466,000 vehicles in the second quarter of 2023.

The flying car is now available for preorder, the Santa Clara, California-based company posted on its website. Carrying one or two occupants, the vehicle will sell for about $300,000.
The “Model A” is 100% electric, drivable on public roads and has vertical takeoff and landing capabilities, the company wrote in its release.
The car will be a Low Speed Vehicle, meaning it won’t go faster than about 25 miles per hour on a paved surface. If a driver needs a faster route, they will be able to use the vehicle’s flight capabilities, according to Alef.
Alef Aeronautics’ ‘Model A’ has a driving range of 200 miles and a flight range of 110 miles. The company plans to start delivering cars by late 2025.
Steam, one of the world’s largest video game storefronts is reportedly not having any of this AI generated stuff.
The data centers and high-performance computers that run artificial intelligence programs, such as large language models, aren’t limited by the sheer computational power of their individual nodes. It’s another problem—the amount of data they can transfer among the nodes—that underlies the “bandwidth bottleneck” that currently limits the performance and scaling of these systems.
The nodes in these systems can be separated by more than one kilometer. Since metal wires dissipate electrical signals as heat when transferring data at high speeds, these systems transfer data via fiber-optic cables. Unfortunately, a lot of energy is wasted in the process of converting electrical data into optical data (and back again) as signals are sent from one node to another.
In a study published in Nature Photonics, researchers at Columbia Engineering demonstrate an energy-efficient method for transferring larger quantities of data over the fiber-optic cables that connect the nodes. This new technology improves on previous attempts to transmit multiple signals simultaneously over the same fiber-optic cables. Instead of using a different laser to generate each wavelength of light, the new chips require only a single laser to generate hundreds of distinct wavelengths of light that can simultaneously transfer independent streams of data.
A fully electric flying car that’ll cost about $300,000 just won approval to start testing on the road – and in the air.
Alef Aeronautics, a Californian automaker, said in a press release it had received a Special Airworthiness Certification from the Federal Aviation Administration (FAA) for the Model A.
It’s the first such approval for a flight-capable car, according to the startup, which has been backed by the likes of SpaceX.
