Every industry will be affected by quantum computing. They will alter the way business is done and the security systems in place which protect data, how we battle illnesses and create new materials, as well as how we tackle health and climate challenges.

As the race to build the first commercially functional quantum computer heats up, here we discuss a handful of the ways quantum computing will alter our world.

Star’s mysterious orbit around black hole proves einstein was right all along—again.

The star, known as S2, has a 16-year elliptical orbit. It came near 20 billion kilometers of our black hole, Sagittarius A*, last year. If Isaac Newton’s traditional definition of gravity is correct, S2 should then continue on its previous orbit’s course through space. But it didn’t work.

When you’re building wearables and glowables, sometimes a flashy rainbow animation is all you need. [Geeky Faye] likes to go a little further, however, and built this impressive necklace that serves to inform on the local air quality.

The necklace consists of a series of Neopixel LED strips, housed within a tidy 3D printed housing made with flexible filament. A dovetail joint makes putting on and removing the necklace a cinch. A TinyPico V2, based on the ESP32, runs the show, as it’s very small and thus perfect for the wearable application. A USB power bank provides power to the microcontroller and LEDs.

Twenty Two Motors. Fifty gears. Eighty Two Hundred RPM. Hundreds of individual pieces, and one sheet of glossy paper cut into a disk. This isn’t a nightmare driven Rube Goldberg machine. Instead, it’s a Lego monstrosity created by [GazR] of [GazR’s Extreme Brick Machines!], and all of these parts are flying in formation for one Lego slicing purpose. In the video below the break, you can see what very well may be the worlds most powerful Lego and Paper table saw.

Starting out with a build that had a mere fourteen motors in a platform that looked quite a lot more like a table saw, [GazR] learned that having only fourteen motors turning a Lego based blade was not a good combination. In the next iteration, the same number of motors were used, but the gearing was increased to bring RPM up, and a Lego toy saw blade took care of cutting duties.

Atomic clocks are the best sensors mankind has ever built. Today, they can be found in national standards institutes or satellites of navigation systems. Scientists all over the world are working to further optimize the precision of these clocks. Now, a research group led by Peter Zoller, a theorist from Innsbruck, Austria, has developed a new concept that can be used to operate sensors with even greater precision irrespective of which technical platform is used to make the sensor. “We answer the question of how precise a sensor can be with existing control capabilities, and give a recipe for how this can be achieved,” explain Denis Vasilyev and Raphael Kaubrügger from Peter Zoller’s group at the Institute of Quantum Optics and Quantum Information at the Austrian Academy of Sciences in Innsbruck.

For this purpose, the physicists use a method from quantum information processing: Variational quantum algorithms describe a circuit of quantum gates that depends on free parameters. Through optimization routines, the sensor autonomously finds the best settings for an optimal result. “We applied this technique to a problem from metrology—the science of measurement,” Vasilyev and Kaubrügger explain. “This is exciting because historically advances in atomic physics were motivated by metrology, and in turn quantum information processing emerged from that. So, we’ve come full circle here,” Peter Zoller says. With the new approach, scientists can optimize quantum sensors to the point where they achieve the best possible precision technically permissible.

PC power supplies haven’t seen a whole lot of change in the last decade or two. We’ve gotten modular cables for easier routing, smaller standards for itty-bitty builds, and that’s about it. But today Intel has finalized the ATX 3.0 standard, coming soon to a full-sized PC case near you. The biggest addition announced today is a new standardized connection for graphics cards and other PCIe devices, delivering up to 600 watts on a single connector.

Currently graphics cards are in a bit of a power pinch. The maximum throughput for an 8-pin ATX rail is 150 watts, so the biggest and most power-hungry GPUs need to double or even triple up, adding extra space requirements and more complex cable routing inside the case. The new 12-pin 12VHPWR connection should be able to deliver more energy than even the most powerful graphics cards need for the next generation or two. Each pin housing is also physically smaller, with a 3.0mm pitch versus 4.2mm on current power supply rails.

Technically it’s 16 total pins (12+4), with four additional data pins squeezed in beneath the primary power pins. This is to manage DC output voltage regulation and a series of new tools designed to regulate high power output efficiently and safely, all handled intelligently by the power supply. According to Intel, the new 12VHPWR connection will be the standard for “most, if not all” PCIe cards using the 5.0 spec.
