In a groundbreaking advancement that merges robotics, materials science, and origami, engineers at Princeton University have developed a shape-shifting material capable of moving, expanding, and responding to electromagnetic commands — all without motors or internal gears. This new class of metamaterial can be remotely controlled, functioning almost like a robot, yet is constructed entirely from passive components.

The research, published in Nature, introduces a metamaterial dubbed the “metabot,” which derives its unique capabilities from its structure rather than its chemical composition. Drawing inspiration from the traditional art of origami, the team designed the metabot to change shape and behavior in response to external magnetic fields.

The record-setting Prowess drone showcases a number of custom-engineered features, including high-speed 3D-printed propellers designed by its creator, Xu. According to Guinness World Records, the 247-gram microdrone utilizes a lightweight carbon fiber frame and a remarkably thin 3D-printed outer shell just 0.4mm thick. Xu developed his own propellers after determining that no commercial models could meet the performance demands of his high-speed application.

Swiss engineer Samuele Gobbi, the Guinness World Record holder for the fastest remote-controlled quadcopter in a heavier weight class, applauded Xu’s accomplishment. “Building a high-speed quadcopter is already very complex, and he has added a weight limit of less than 250 grams to it, which makes me admire his achievement,” Gobbi remarked.

Collagen, one of the most abundant proteins in the human body, plays a critical role in providing structure, stability, and mechanical strength to tissues. Yet, despite its prevalence, some aspects of collagen’s behavior—particularly its orientation within tissues—remain shrouded in mystery. A new study from researchers at Yokohama National University sheds light on this complex topic and introduces a promising new method for fabricating collagen-based tissues with unprecedented precision.

Understanding the orientation of collagen fibers is vital, as it influences cell behavior and tissue function. Existing methods for modeling collagen structures—such as magnetic alignment and electrospinning—have notable drawbacks. Magnetic beads can remain embedded in the final structure, while volatile organic solvents pose safety and environmental concerns. Additionally, these techniques often fall short when it comes to accurately replicating the complex, multi-directional orientations found in natural tissues like the dermis or skull.

In a historic first for genetic medicine, doctors and scientists at Children’s Hospital of Philadelphia (CHOP) and Penn Medicine have successfully used a customized CRISPR-based gene editing therapy to treat a baby with a rare, life-threatening metabolic condition. The patient, known as KJ, was born with carbamoyl phosphate synthetase 1 (CPS1) deficiency, a disorder that disrupts the body’s ability to process nitrogen, causing toxic ammonia buildup in the blood.

This is the first time in the world that a CRISPR therapy has been specifically tailored and administered to a single patient, marking a revolutionary advancement in personalized medicine.

Air conditioning is a modern necessity, offering comfort in a warming world. But this comfort comes at a hidden cost—traditional air conditioners rely on harmful refrigerants that contribute significantly to global warming. Ironically, the very systems designed to cool us are heating the planet.

To change that, a spin-out from the University of Cambridge called Barocal is pioneering a groundbreaking solution: a “soft, waxy solid refrigerant” with zero carbon emissions. Unlike conventional systems, which depend on gaseous fluids prone to leakage and environmental damage, Barocal’s innovation uses solid-state materials that offer a cleaner, greener alternative.

In a breakthrough that could transform global infrastructure, researchers in the U.S. have engineered a new form of self-healing concrete inspired by nature. Powered by air, sunlight, and water, the innovative material uses synthetic lichen to autonomously repair its own cracks, offering a sustainable and low-maintenance alternative to traditional concrete.

The project, led by Dr. Congrui Grace Jin, an assistant professor at Texas A&M University, mimics the natural symbiosis found in lichens—resilient organisms formed through a partnership between fungi and algae or cyanobacteria. By replicating this biological relationship with engineered microbes, Jin and her team have created a concrete system capable of maintaining and reinforcing itself without external intervention.

A team of scientists from McGill University and Polytechnique Montréal has developed a groundbreaking method to create hydrogels using ultrasound—offering a faster, cleaner, and more sustainable alternative to traditional manufacturing techniques. This new approach eliminates the need for potentially toxic chemical initiators and results in hydrogels that are stronger, more flexible, and more resistant to freezing and dehydration.

Hydrogels are water-absorbing polymer networks commonly used in medical and industrial applications, such as wound dressings, drug delivery, tissue engineering, contact lenses, and soft robotics. Traditional fabrication methods typically depend on chemical initiators to trigger gel formation, some of which can pose safety risks—particularly for biomedical use.

A team of engineers from Australia and China has developed a sponge-like device that can extract drinkable water from the air, even in low humidity conditions where traditional methods like fog harvesting and radiative cooling typically fail. Powered entirely by the sun, the innovation offers a promising solution for water scarcity in remote or disaster-affected areas.

Designed by researchers from RMIT University in Melbourne and five Chinese institutions, the device functions effectively across a wide range of environmental conditions, including humidity levels between 30% and 90% and temperatures from 5 to 55 degrees Celsius.

What once required a team of engineers physically pushing car chassis through factory assembly lines is now handled entirely in simulation. At BMW, digital twins—virtual replicas of entire factories—allow engineers to test and refine production processes long before a single piece of machinery is installed. This shift is part of a larger transformation happening in manufacturing, driven by what’s now being called the industrial metaverse.

While consumer visions of the metaverse have faltered, the industrial application of these technologies is thriving. The industrial metaverse—an ecosystem of interconnected simulations, sensors, 3D models, and augmented reality—offers manufacturers the ability to virtually plan, test, and optimize physical processes in a digital environment. According to the World Economic Forum, the industrial metaverse is expected to reach a global market value of $100 billion by 2030.

Set against the star-filled skies of Chile’s Atacama Desert, UT4—one of four 8-meter telescopes at the European Southern Observatory’s Very Large Telescope (VLT) array in Paranal—stands as a technological marvel. With its advanced adaptive optics system, UT4 delivers images so sharp they rival those captured from space.

At night, beams of light erupt from UT4’s dome, slicing through the darkness. These beams originate from the 4 Laser Guide Star Facility (4LGSF), which allows the telescope to create artificial stars high above the Earth. The lasers excite sodium atoms located about 90 kilometers up in the atmosphere, causing them to glow. These glowing spots act as reference points, or “guide stars,” allowing astronomers to measure how Earth’s atmosphere distorts incoming light.

LEAP 71, a company focused on computer-aided engineering, is expanding its computational development platform to design rocket engines capable of generating thrust in the meganewton range. Building on successful trials of smaller engines, the company is now developing two new reference propulsion systems: the 200 kN XRA-2E5 aerospike engine and the 2000 kN XRB-2E6 bell-nozzle engine.

At the core of this initiative is “Noyron,” a generative development model that encodes engineering logic into software. This model automates the creation of manufacturable rocket engine designs, including complex turbomachinery components necessary for engine functionality.

Mesenchymal stem/stromal cells (MSCs) are emerging as a promising tool in cell therapy due to their strong immunomodulatory and anti-inflammatory properties, their capacity for tissue regeneration, and a favorable safety profile. Unlike other cell-based therapies, such as CAR T cells that may trigger severe immune responses like cytokine storms, wild-type MSCs have shown no such adverse reactions when administered to humans. However, the widespread clinical application of MSCs has been limited by challenges in producing therapeutically effective cells consistently and at scale. To date, only one MSC-based therapy has been approved by the U.S. Food and Drug Administration (FDA).

A key obstacle in developing MSC therapies is the ongoing requirement for new tissue donations from various donors. This dependence leads to high variability and restricted batch sizes due to the limited expansion capacity of each donor-derived sample.
