Traditionally, brain-computer interfaces (BCIs) have operated by interpreting brain signals and translating them into mechanical responses. But a groundbreaking new study published in Nature Electronics reveals a BCI that doesn’t just listen—it actively responds. In research led by a team in China, scientists have developed a two-way BCI system that not only decodes a user’s intentions but also provides real-time feedback to shape brain activity, creating a more interactive and adaptive interface.

At the heart of this innovative system is a memristor, a unique electronic component capable of “remembering” past voltage or current by altering its resistance. This characteristic makes it particularly well-suited for mimicking synapses in neuromorphic circuits, which are designed to replicate the brain’s neural functions.

It sounds like something straight out of a sci-fi movie: a metal that’s as strong as aluminum, but completely transparent. Yet, transparent metal is no longer a fantasy—it’s very real, and could soon revolutionize everything from electronics to aerospace technology.

Imagine replacing the glass on your next smartphone or tablet with a metal display. That possibility is now closer than ever, thanks to an exciting new breakthrough in the field of materials science. Scientists have developed a way to make this ultra-durable, scratch-resistant transparent material more affordable and accessible than ever before.

As part of its ambitious plans to become a more walkable city, Dubai is taking steps to reduce traffic congestion by partnering with The Boring Company. The collaboration aims to create an innovative network of underground tunnels that will allow people to travel quickly and efficiently beneath the city, bypassing the heavy traffic that often clogs the streets.

This new initiative, called the Dubai Loop, will be developed by The Boring Company in partnership with the Roads and Transport Authority (RTA). It is inspired by similar projects, like the one in Las Vegas, and seeks to transform Dubai’s transportation infrastructure. The initial phase of the project will span 17 kilometers (10.5 miles) and include 11 stations, designed to carry over 20,000 passengers per hour. The ultimate goal is to expand the Dubai Loop throughout the Emirate, creating a comprehensive underground transit network.

Scientists have discovered a groundbreaking method to break down plastics like Plexiglass into their original building blocks, known as monomers, making them easier to reuse. This breakthrough could play a crucial role in addressing the growing issue of plastic waste, which continues to pose significant environmental challenges.

Traditional plastic recycling methods typically involve shredding, cleaning, and remelting materials, but these processes degrade the quality of the plastic over time. In contrast, breaking plastics down into their monomer components allows for more thorough purification, enabling the creation of high-quality materials without a loss of performance.

Chinese researchers have developed the world’s first two-way adaptive brain-computer interface (BCI), a breakthrough that promises to revolutionize the efficiency and practicality of brain-machine interactions. This cutting-edge system, detailed in a new study, is said to boost performance by over 100 times compared to traditional BCIs, marking a significant leap toward making BCIs a staple in both medical and consumer technology.

The innovative system, a collaboration between Tianjin University and Tsinghua University, introduces a new paradigm where both the brain and the machine can learn from each other, unlike conventional BCIs, which only decode brain signals. This dynamic two-way communication ensures long-term stability and adaptability—critical factors for making BCIs reliable and practical for everyday use. “Our work introduces the concept of brain-computer co-evolution, demonstrating its feasibility as the first step toward mutual adaptation between biological and machine intelligence,” said Xu Minpeng, a co-author from Tianjin University.

After years of extensive testing and development, a revolutionary material known as Composite Metal Foam (CMF) is now ready for full-scale production. This cutting-edge material combines the strength of steel with the lightweight properties of aluminum, making it not only strong and durable but also highly resistant to ballistic impacts, fire, and radiation.

The brainchild of North Carolina State University engineer Afsaneh Rabiei, CMF has been under development for over a decade. Recently, Advanced Materials Manufacturing (AMM) announced that CMF is now ready for industrial production, opening the door to a wide range of applications in various engineering fields.
