What if you could code just by talking out loud? GitHub CEO Thomas Dohmke shows how, thanks to AI, the barrier to entry to coding is rapidly disappearing — and creating software is becoming as simple (and joyful) as building LEGO. In a mind-blowing live demo, he introduces Copilot Workspace: an AI assistant that helps you create code when you speak to it, in any language.

Dead satellites and other debris are constantly burning up as they fall out of Earth’s orbit.

Conventional wisdom is destroying all that space junk is good, because it keeps orbit less cluttered. But it may have harmful effects on our planet’s magnetic field, as plasma physicist and former Air Force research scientist Sierra Solter — the author of a contentious and yet-to-be-peer-reviewed paper — argues in a new essay for The Guardian.

Ventures like Elon Musk’s SpaceX are launching thousands of satellites into orbit, and tens of thousands more are soon to follow as interest in the private space industry and space tourism continues to grow.

What does “equals” mean? For mathematicians, this simple question has more than one answer, which is causing issues when it comes to using computers to check proofs. The solution might be to tear up the foundations of maths.

Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, researchers from Japan tackled these issues by developing a novel piezoelectric composite material made from electrospun polyvinylidene fluoride nanofibers combined with dopamine. Sensors made from this material showed significant performance and stability improvements at a low cost, promising advancements in medicine, healthcare, and robotics.

The world is accelerating rapidly towards the intelligent era—a stage in history marked by increased automation and interconnectivity by leveraging technologies such as artificial intelligence and robotics. As a sometimes-overlooked foundational requirement in this transformation, sensors represent an essential interface between humans, machines, and their environment.

However, now that robots are becoming more agile and wearable electronics are no longer confined to science fiction, traditional silicon-based sensors won’t make the cut in many applications. Thus, flexible sensors, which provide better comfort and higher versatility, have become a very active area of study. Piezoelectric sensors are particularly important in this regard, as they can convert mechanical stress and stretching into an electrical signal. Despite numerous promising approaches, there remains a lack of environmentally sustainable methods for mass-producing flexible, high-performance piezoelectric sensors at a low cost.

In relationships, sharing closer spaces naturally deepens the connection as bonds form and strengthen through increasing shared memories. This principle applies not only to human interactions but also to engineering. Recently, an intriguing study was published demonstrating the use of quantum dots to create metasurfaces, enabling two objects to exist in the same space.

Professor Junsuk Rho from the Department of Mechanical Engineering, the Department of Chemical Engineering, and the Department of Electrical Engineering, PhD candidates Minsu Jeong, Byoungsu Ko, and Jaekyung Kim from the Department of Mechanical Engineering, and Chunghwan Jung, a PhD candidate, from the Department of Chemical Engineering at Pohang University of Science and Technology (POSTECH) employed Nanoimprint Lithography (NIL) to fabricate metasurfaces embedded with quantum dots, enhancing their luminescence efficiency. Their research was recently published in Nano Letters (“Printable Light-Emitting Metasurfaces with Enhanced Directional Photoluminescence”).

The complex computer model takes into account weather and climate systems as well as our impact on the planet.

The Expedition 71 crew at the International Space Station is gearing up for a spacewalk focused on scientific and maintenance tasks, including the installation of a spare pump and the retrieval of faulty communications hardware. Additionally, Commercial Crew astronauts have extended their stay to facilitate further systems checks on the Starliner spacecraft. Amidst these preparations, the crew continues to engage in routine health checks and scientific experiments across various modules of the station.

Aboard the International Space Station (ISS), the Expedition 71 crew is getting ready for a spacewalk this week while two Commercial Crew astronauts will spend a few extra days. In addition, the orbital residents continued their advanced space research and conducted eye and ear exams on Monday.

As some entities identify new (or at least overlooked) sources to meet the growing demand for rare earth materials, others are looking toward new tools. UK deep-tech company Materials Nexus announced on Tuesday that it has designed a new rare-earth-free permanent magnet with the help of its AI platform. It says the AI-driven discovery and development process was 200 times faster than the resource-intensive manual route, bringing new hope to an electrifying world with a growing appetite for powerful magnets.

With the world moving away from internal combustion engines and gradually embracing electric mobility, the demand for compact, high-power motors is rapidly rising. By far the most popular option in the automotive industry right now is the permanent magnet motor, which powers upward of 80% of modern electric vehicles.

Materials Nexus estimates that demand for permanent magnets will grow tenfold by 2030, in the EV industry alone. And it’s not just electric cars and trucks, either. Permanent magnet motors are in demand for many applications, including robotics, drones, wind turbines and HVAC equipment.
