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.
