Miniaturization is progressing rapidly in many fields, and the trend toward the creation of ever smaller units is also prevalent in the world of robot technology. In the future, minuscule robots used in medical and pharmaceutical applications might be able to transport medication to targeted sites in the body. Statistical physics can contribute to the foundations for the development of such technologies.

A team of researchers at Johannes Gutenberg University Mainz (JGU) has now taken a new approach to the issue by analyzing a group of robots and how they behave as collectives of motile units based on the model of active Brownian particles. The team’s findings demonstrating that there may be an alternative route to realize programmable active matter have been published in Science Advances.

Researchers are looking for new ways to perform tasks on the micro-and nanoscale that are otherwise difficult to realize, particularly as the miniaturization of devices and components is beginning to reach physical limits. One new option being considered is the use of collectives of robotic units in place of a single robot to complete a task.

Researchers have developed a quantum key distribution (QKD) system based on integrated photonics that can transmit secure keys at unprecedented speeds. The proof-of-principle experiments represent an important step toward real-world application of this highly secure communication method.

QKD is a well-established method of providing secret keys for secure communication between distant parties. By using the quantum properties of light to generate secure random keys for encrypting and decrypting data, its security is based on the laws of physics, rather than computational complexity like today’s communication protocols.

“A key goal for QKD technology is the ability to simply integrate it into a real-world communications network,” said research team member Rebecka Sax from the University of Geneva in Switzerland. “An important and necessary step toward this goal is the use of integrated photonics, which allows to be manufactured using the same semiconductor technology used to make silicon computer chips.”

Every color, every flash, every sunray exacts a toll on the light-sensitive tissues at the back of our eyes, producing toxic materials that risk damaging the very cells that allow us to see.

Thankfully, the pigment responsible for darkening our hair, skin, and eyes moonlights as a clean-up crew, mopping up one such dangerous compound before it accumulates into damaging clumps.

An investigation by researchers from the University of Tübingen in Germany and Yale University has revealed the removal process is somewhat unusual as far as biochemistry goes, relying upon a strange quirk of quantum-like behavior.

On Tuesday, the CEO of the UK Space Agency Graham Turnock announced the UK would be working more closely with Australia in a “world-first Space Bridge” agreement which will focus on delivering a plane—or rocket, really—to shuttle passengers from continent-to-continent in just four hours. While flights from London to the Big Apple will reportedly take a skerrick over 60 minutes.

It’s all courtesy of a new hypersonic engine SABRE (Synergetic Air-Breathing Rocket Engine)—which the scientists at Reaction Engines are currently developing. Fueled by a combination of hydrogen and oxygen, SABRE is capable of powering a plane to Mach 5.4 (4,000 mph) for speedy commercial travel—that’s around five times the speed of sound—or Mach 25 (19,000 mph) when soaring in space. It’s supposedly greener and cheaper than current air travel, too.

The widespread use of advanced artificial intelligence tools like ChatGPT means the rapidly developing technology is being used in workplaces across the country whether employers are aware of it or not.

So, for companies that have not yet developed ground rules for AI use, you’re being put on alert: It’s time to update your employee handbook, an human resources expert says.

Jennifer Morehead, owner and CEO of Flex HR, which handles outsourced human resources services for major firms like Harley-Davidson and Kimberly Clark, says there are an array of issues AI firms need to consider now that the tools are becoming increasingly accessible in the workplace.
