A groundbreaking satellite named LignoSat, developed by a team at Kyoto University in collaboration with logging company Sumitomo Forestry, is set to revolutionize space technology with its unique construction from magnolia wood. This 10-centimeter cube aims to pave the way for environmentally friendly satellites that completely burn up upon re-entering Earth’s atmosphere.

The LignoSat project began in April 2020, with researchers evaluating various types of wood for their durability in harsh space conditions. Magnolia emerged as the top choice due to its strength and workability. Using traditional Japanese joinery techniques, the satellite’s wooden panels are seamlessly joined without screws or glue.

A groundbreaking power transmission technology has emerged in Woburn, Massachusetts, promising to redefine energy distribution efficiency while minimizing visual impact. VEIR, a startup co-founded by MIT alumnus Tim Heidel, has developed an innovative approach using superconducting cables and an advanced cooling system. This technology boosts transmission capacity, surpassing conventional lines by five to ten times, addressing the urgent global need for robust transmission infrastructure to support renewable energy integration and grid resilience.

VEIR’s technology relies on superconducting cables and an advanced cooling system, enabling their lines to initially carry up to 400 megawatts of power, with plans for even higher capacities in the future. “We can deploy much higher power levels at much lower voltage, and so we can deploy the same high power but with a footprint and visual impact that is far less intrusive,” said Heidel. This breakthrough not only increases capacity but also addresses regulatory and community opposition that have hindered many transmission projects.

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.”
