In a remarkable feat of engineering and automation, China has recently completed the world’s first fully unmanned road resurfacing project, covering an impressive 157.79 kilometres of expressway without the involvement of a single human construction worker. This innovative achievement showcases China’s rapid advancements in construction technology and its commitment to pushing the boundaries of what’s possible in infrastructure development.

The Autonomous Fleet

The project utilised a fleet of autonomous road construction vehicles, including drones and robots, to carry out the entire resurfacing process. This cutting-edge approach marks a significant departure from traditional road construction methods, which typically rely heavily on human labour.

Parachutes have many applications, decelerating everything from skydivers to supersonic-speed scientific payloads. Regardless of what a parachute is slowing down, two things remain constant: the parachute must withstand large amounts of force, and it is crucial to ensuring the safety of whatever it’s carrying. To choose parachute materials that do their jobs effectively, it’s important to fully understand what happens while a parachute is opening and on its way down.

Beckman Institute for Advanced Science and Technology researchers Cutler Phillippe, Francesco Panerai and Laura Villafañe Roca have used computed tomography scans to study the fiber-scale properties of parachute textiles and link them to larger-scale behavior. Their work is published in the American Institute of Aeronautics and Astronautics (AIAA) Journal.

“We know generally how a impacts the performance of the parachute,” said Phillippe, a graduate student in the Department of Aerospace Engineering at the University of Illinois Urbana-Champaign. “But we don’t know from an experimental standpoint how that performance is related to the individual fiber motions within the textile as well as the dynamic properties of, for example, a bundle of fibers.”

Microsoft on Monday said it was enhancing its AI offerings with new autonomous agent capabilities as the tech titan aims to accelerate business adoption of artificial intelligence.

AI agents are specialized programs designed to perform autonomously, such as sifting through sales leads or handling customer service inquiries.

The AI agent has become the newest buzzword for major software companies that are investing billions in powerful AI models, which they believe will shape the future of computing.

Love this article from Our World in Data which describes how far we have come as a species and what challenges remain ahead. “Very few think the world is making progress. In this article, we look at the history of global living conditions and show that the world has made immense progress in important aspects.”

The data in this article uses a previous release of the World Bank’s poverty and inequality data in which incomes are expressed in 2011 international-$.

The World Bank has since updated its methods, and now measures incomes in 2017 international-$. As part of this change, the International Poverty Line used to measure extreme poverty has also been updated: from $1.90 (in 2011 prices) to $2.15 (in 2017 prices).

This has had little effect on our overall understanding of poverty and inequality around the world. But because of the change of units, many of the figures mentioned in this article will differ from the latest World Bank figures.

Every cell is beholden to a phenomenon called cell fate, a sort of biological preset determined by genetic coding. Burgeoning cells take their developmental cues from a set of core genetic instructions that shape their structure and function and how they interact with other cells in the body.

To you or me, it’s biological law. But to a group of researchers at Stanford Medicine, it’s more of a suggestion. Unconstrained by the rules of evolution, these scientists are instead governed by a question: What if?

What if you could eat a vaccine? Or create a bacterium that could also detect and attack cancer? What if furniture could grow from a seed?

Title: Creating a persona for ChatGPT or other generative AI models serves several important purposes:

See…

I’ve been exploring the development of deep persona for the past few days.

I’ve been fascinated by GenAI ever since ChatGPT-3 came out last year. I’ve found it incredibly useful for brainstorming and speeding up the development of tools and processes. It generally covers the basics, allowing me to concentrate on more advanced topics and specifics based on context and experience.

In 2019, researchers from the Massachusetts Institute of Technology made headlines when they created the “blackest black” material made from carbon nanotubes —ten times blacker than any material that had been manufactured at that time—a material so black that it had the ability to absorb 99.995% of incident light. Such research in light absorption is not a trivial pursuit or mere aesthetics, there are many technologies that can benefit from maximizing light absorption—for instance, in photovoltaics because of the need to absorb and convert as much light as possible into electricity, or on the interior surface of a light sensor because of the need to minimize unwanted stray light. The physics of light absorption can get quite complex when you get into the details, as what we non-technically consider as “black” is usually not a perfect absorber. Indeed, there are many ways to create something that can absorb some light, but the endeavor gets increasingly more difficult the closer one attempts to achieve 100% absorption.

That takes some serious physics.

Now, physicists in Austria and Israel report in the journal Science that they have engineered a light trap that utilizes the quantum properties of electromagnetic waves— in which waveforms undergo constructive or destructive interference when combined in just the right manner—to generate an anti-laser that has near-perfect light absorption [1]. Because the light trap functions essentially as a time-reversed laser, where instead of multiple passes of single-wavelength light for maximum stimulated emission of photons the multiple passes are engineered for maximum absorption, the device is a veritable anti-laser.

But when something out of the ordinary happens, the situation can quickly get scary, because most updates are only delivered by audio announcements. A Deaf traveller may miss their train because it was moved to a different platform, or watch as their station whizzes by because the train isn’t stopping there today. They may also remain on a train carriage in an emergency after everyone else has evacuated, and have to be rescued by station staff.

Every single one of these examples has been drawn from the real life experiences of Deaf people in Sydney. But my colleagues and I are working with Sydney Trains and members of the Australian Deaf community to develop an advanced, artificial intelligence (AI)-powered signing avatar which can automatically translate audio announcements into Auslan.
