For more than 15 years, a group of scientists in Texas has been diligently working on creating devices that can “see” through barriers using medium-frequency electromagnetic waves. Now, they seem closer than ever to achieving their goal.

In an interview with Futurism, Kenneth O, an electrical engineering professor at the University of Texas, explained that the new tiny imager chip developed by his research team can detect the outlines of items through barriers like cardboard. This breakthrough is the result of continuous advances and innovations in microprocessor technology over the past two decades.

Researchers have developed a new class of materials called “glassy gels,” which are extremely hard and difficult to break despite containing over 50% liquid. The simplicity of producing glassy gels makes them promising for various applications. A paper titled “Glassy Gels Toughened by Solvent,” detailing this work, appears in the journal Nature.

Traditionally, gels and glassy polymers are viewed as distinct materials. Glassy polymers are hard, stiff, and often brittle, used in products like water bottles and airplane windows. Gels, such as contact lenses, contain liquid and are soft and stretchy. “We’ve created a class of materials that we’ve termed glassy gels, which are as hard as glassy polymers but can stretch up to five times their original length without breaking,” says Michael Dickey, the corresponding author of the paper and the Camille and Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University. “What’s more, once the material has been stretched, you can return it to its original shape by applying heat. Additionally, the surface of the glassy gels is highly adhesive, which is unusual for hard materials.”

A groundbreaking new material made from barley starch blended with fiber from sugarbeet waste—a robust substance that composts if it ends up in nature—has been developed at the University of Copenhagen. In the long term, the researchers hope that their invention can help curb plastic pollution while reducing the climate footprint of plastic production.

Enormous islands of plastic float in our oceans, and microscopic particles infiltrate our bodies. The durability, malleability, and low cost of plastics have made them ubiquitous, from packaging to clothing to aircraft parts. However, plastics have significant downsides: they contaminate nature, are difficult to recycle, and their production emits more CO2 than all air traffic combined.

Researchers at the ATLAS Institute at the University of Colorado Boulder have developed an innovative DIY machine that produces textile fibers from sustainable materials, such as gelatin. This machine could revolutionize the fashion industry by offering a solution to the significant environmental impact of textile waste.

Led by doctoral student Eldy Lázaro Vásquez, the research team has created a machine capable of spinning textile fibers from gelatin, a protein commonly derived from animal byproducts. These fibers feel similar to flax and can dissolve in hot water within minutes to an hour, providing a sustainable alternative to traditional textiles, which often end up in landfills.

Wayve, a leading innovator in Embodied AI for self-driving technologies, has announced the launch of PRISM-1, a groundbreaking 4D reconstruction model designed to significantly enhance the testing and training of its Advanced Driver Assistance Systems (ADAS) and autonomous driving technology. PRISM-1 represents a major advancement in 4D reconstruction, enabling scalable and realistic resimulations of complex driving scenes with minimal engineering or labeling input.

First showcased in December 2023 through Wayve’s Ghost Gym neural simulator, PRISM-1 employs novel view synthesis to create precise 4D scene reconstructions (3D in space plus time) using only camera inputs. This method promises to revolutionize simulation for autonomous driving by accurately and efficiently simulating the dynamics of complex and unstructured real-world environments. PRISM-1 powers the next generation of Ghost Gym simulations and departs from traditional methods that rely on LiDAR and 3D bounding boxes. Instead, it uses novel view synthesis techniques to accurately depict moving elements such as pedestrians, cyclists, vehicles, and traffic lights, capturing precise details like clothing patterns, brake lights, and windshield wipers.

Researchers from Tokyo Tech and the National Institute of Information and Communications Technology (NICT) have unveiled a revolutionary D-band CMOS transceiver chipset, which boasts a 56 GHz signal-chain bandwidth and has achieved an unprecedented wireless transmission speed of 640 Gbps through integrated circuits. This innovative chipset holds immense potential for the advancement of next-generation wireless systems.

The demand for faster data speeds and the management of increasing data traffic are driving wireless systems to operate at higher millimeter-wave frequency bands. Current high-band 5G systems already provide impressive speeds up to 10 Gbps within the 24-47 GHz frequency range. However, future mobile communication systems aim to explore even higher frequencies, with the D-band (110 to 170 GHz) anticipated to play a crucial role in the evolution of wireless technology.

In mammals, only 3% of the genome encodes proteins essential for life and development. However, genes do not operate in isolation; they are regulated by other DNA sequences known as enhancers, which function like switches to turn genes on or off. Researchers at the University of Geneva (UNIGE) have identified 2,700 enhancers that regulate genes involved in bone growth.

Our height is largely inherited, and many genetic diseases impact bone growth. The root cause of these conditions might lie not in the genes themselves, but in the enhancers that activate them. Guillaume Andrey, a researcher at UNIGE, explains that enhancers signal DNA to produce RNA, which in turn synthesizes proteins. While the locations of bone growth genes are known, the specific enhancers controlling them had remained elusive.

Tokyo Steel Japan has unveiled its new proprietary green steel brand, Enso. The Enso circle, a symbol deeply rooted in Japanese culture, represents eternity, infinity, harmony, balance, and the cyclical nature of life. This emblem reflects Tokyo Steel’s commitment to the circular economy through its products. The Enso logo, transitioning from charcoal to green, signifies the company’s shift from carbon-intensive production to sustainable green steel.

Tokyo Steel reduces embodied carbon emissions by using electric arc production with recycled steel scrap and highly efficient operating processes, bypassing the emission-intensive steps typical in traditional blast furnace methods. The initial Enso product range includes Hot Rolled Coil (HRC) and Hot Rolled Plate (HRP), with plans for downstream expansion in the future.

A group of researchers from Switzerland’s École Polytechnique Fédérale de Lausanne (EPFL) believes they have designed the thinnest metallic nanowire ever created. Remarkably, this wire remains stable even at 0 Kelvin.

The team, led by Chiara Cignarella with members Davide Campi and Nicola Marzari, devised an innovative approach to discover this nanowire. They aimed to leverage crystalline structures to identify suitable candidates without the need to build thousands in a lab.

Inspired by the movie Jurassic Park, a team of MIT researchers has developed a groundbreaking method to store DNA for extended periods using a glassy, amber-like polymer. This innovative approach allows for the preservation of DNA at room temperature, circumventing the need for energy-intensive freezing methods.

Traditional DNA storage methods require freezing temperatures, which consume substantial energy and are impractical in many regions. The new method developed by the MIT team stores DNA at room temperature, protecting it from damage caused by heat or moisture.

Recent tests have shown that MASH Makes’ waste-based biofuel is a viable ‘drop-in’ replacement for fossil fuels in the shipping sector. In collaboration with the global shipping company NORDEN, this innovative biofuel will now be trialed in live vessels. These trials mark a significant step towards achieving net-zero emissions, with biofuel poised to play a crucial role in decarbonizing shipping and heavy industry.

Shipping, which facilitates over 80% of global trade, consumes more than 330 million tons of fossil fuel annually, accounting for over 3% of global CO2 emissions—more than the entire country of Germany. Decarbonizing this essential part of the global economy is vital to meeting climate goals, but traditional green technologies have struggled to achieve this.

Researchers at Tsinghua University in China have developed a groundbreaking photonic chip that can process, transmit, and reconstruct images in mere nanoseconds. This innovative chip bypasses the traditional optical-to-electronic data conversion used by conventional chips, significantly enhancing the speed and efficiency of image processing.

Machine vision, a rapidly evolving field where cameras, sensors, and algorithms collaborate to interpret the world and execute specific tasks, has traditionally relied on transferring data over long distances for analysis. This process, however, is too slow for many real-time applications. “The world is entering an AI era, but AI is very time- and energy-exhaustive,” said Lu Fang, associate professor at Tsinghua University’s Department of Electronic Engineering. In today’s fast-paced world, machine vision now requires on-device data processing, known as edge computing, to enable quicker decision-making.
