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.
