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.

Researchers at MIT, led by Damian Stefaniuk, have developed a groundbreaking material that could revolutionize energy storage. By combining water, cement, and carbon black—a highly conductive material commonly used in car tires—Stefaniuk and his team created a supercapacitor with the potential to significantly impact renewable energy storage.

Unlike lithium-ion batteries, supercapacitors are not ideal for long-term energy storage but excel at rapid charging and discharging. This makes them an intriguing complement to conventional batteries. The novel carbon-cement supercapacitor developed by Stefaniuk’s team could alleviate pressure on the electrical grid by providing efficient storage solutions for green energy, which often fluctuates throughout the day.

A new trend in green technology focuses on converting energy from water or air into drinkable water. DrinkingMaker, an innovative company, is set to launch DrinkingWater, a solar-powered, multifunctional dispenser that extracts water from the air.

Amid the climate crisis and increasing water scarcity, DrinkingMaker drew inspiration from desert beetles and cacti to develop DrinkingWater, an advanced air-to-water (AWD) dispenser. This new technology is designed to yield up to 19 liters of water per day and offers optional mineral-rich filter cartridges, allowing users to customize their mineral water to personal preferences.

Cirrus Therapeutics, the University of Bristol, and London’s Global University Institute of Ophthalmology have unveiled a revolutionary treatment for age-related macular degeneration (AMD), the leading cause of vision loss among older adults. Highlighted on the cover of Science Translational Medicine, this groundbreaking research shows that increasing levels of a specific protein, IRAK-M, in retinal cells could offer a highly effective therapy for AMD.

AMD severely impacts vision, starting with blurred sight or a central black dot, which can expand, leading to complete central vision loss. Currently, around 200 million people worldwide suffer from AMD, with projections suggesting this number will rise to 288 million by 2040 due to aging populations. The exact cause of AMD is complex, involving a mix of aging, environmental, and lifestyle factors.

A new heat-to-energy converter has achieved a record-breaking efficiency of 44%, significantly higher than the average steam turbine’s 35%. This innovative thermophotovoltaic (TPV) cell marks a significant advancement towards sustainable, grid-scale renewable energy storage.

As renewable energy prices plummet, the challenge lies in their intermittency. Critics often point out the variability of solar and wind power, asking, “What happens at night or when the wind isn’t blowing?” The solution lies in effective energy storage systems, which can bridge the gap during periods of low renewable energy generation. Traditional options include lithium-ion batteries and emerging technologies like iron-air, water-in-salt, and flow batteries. However, one of the most promising methods involves storing energy as heat.

A Swiss biocomputing startup, FinalSpark, has launched an innovative online platform called Neuroplatform, providing remote access to 16 human brain organoids. This groundbreaking service claims to be the world’s first online platform delivering access to biological neurons in vitro. Notably, FinalSpark states that bioprocessors like those used in Neuroplatform consume a million times less power than traditional digital processors, promising a significant reduction in the environmental impacts of computing.

FinalSpark asserts that its Neuroplatform is capable of learning and processing information. Its remarkably low power consumption could drastically cut the energy costs associated with computing. According to a recent research paper by FinalSpark, training a single large language model (LLM) like GPT-3 required approximately 10 GWh—around 6,000 times the annual energy consumption of an average European citizen. By deploying bioprocessors, such immense energy expenditure could be significantly reduced.
