A fundamental trade-off between the resolution of a clock and its accuracy could have important implications for quantum computers, which must measure short timescales accurately.

Few studies have investigated the structural properties of organic mixed ionic-electronic conductors in relation to the transient device characteristics. Here, Kim et al. show that backbone-dependent molecular orientation affects ion injection directionality, which determines ion mobility and transient response.
The brain-computer interface (BCI) space continues to rise in notoriety, and a number of players are throwing their hats in the ring.
Such technologies could enable users to control a computer with their brain, or even go beyond that. Countless immobile people someday could control a mouse cursor, keyboard, mobile device/tablet, wheelchair or prosthetic device by only thinking.
Big names have already established their presence in the space. Elon Musk’s Neuralink continues to make headway, while Bill Gates-and Jeff Bezos-backed Synchron has an innovative catheter-delivered implant. Blackrock Neurotech, which has a next-generation BCI, has been implanting its Utah Array in patients since 2004.

Traditional teaching methods often struggle with effectively conveying complex quantum concepts.
It comes 3 years after Amazon debuted its ‘handy’ authentication service for consumers.
Amazon’s cloud computing subsidiary AWS (Amazon Web Services) has lifted the lid on a new palm-scanning identity service that allows companies to authenticate people when entering physical premises.
The announcement comes as part of AWS’s annual Re: Invent conference, which is running in Las Vegas for the duration of this week.
Amazon One Enterprise, as the new service is called, builds on the company’s existing Amazon One offering which it debuted back in 2020 to enable biometric payments in Amazon’s own surveillance-powered cashierless stores. Visitors to Amazon Go stores can associate their payment card with their palm-print, allowing them to enter the store and complete their transaction by hovering their hand over a scanner.

Transistors were a pivotal innovation in the evolution of electronic technology, and they have played a critical part in the miniaturization and advancement of electronic equipment. However, they could be even better.
Physicists at Martin Luther University Halle-Wittenberg (MLU) and Central South University in China have demonstrated that, combining specific materials, heat in technical devices can be used in computing. Their discovery is based on extensive calculations and simulations. The new approach demonstrates how heat signals can be steered and amplified for use in energy-efficient data processing.
The team’s research findings have been published in the journal Advanced Electronic Materials (“PT-Symmetry Enabled Spintronic Thermal Diodes and Logic Gates.”).
Information signals are encoded as thermal spin waves (red arrows). Logical operations are realized with two magnetic strips (signal conductors) and precisely controlled with current pulses in a spacer (platinum). (Image: Berakdar group)
A high-tech soccer ball that helps with more accurate offside decisions will make its European Championship debut next year in Germany after being used at the 2022 World Cup.
European soocer governing body UEFA and manufacturer Adidas unveiled the ball for Euro 2024 in Berlin on Wednesday. It is named “Fussballliebe,” the German word for “love of soccer,” and will be used at next year’s 51-game tournament from June 14-July 14.
A chip fixed on a gyroscope inside the ball sends data 500 times per second to record the point at which it is kicked. The “kick point” helps match officials make offside decisions using multiple camera angles to create 3D visualizations that illustrate player movement.
The firm claims that the technology “testing in computer simulations is proving superior to legacy four-stroke engine architectures.”

The Wisconsin-headquartered company has now successfully concluded sophisticated simulation analyses for a hydrogen-fueled version of its engine. The firm received FAA certification for its 180 horsepower DHK180 jet-fueled aircraft piston engine in May.
