South Korea’s Korea Superconducting Tokamak Advanced Research (KSTAR) reactor has achieved a groundbreaking milestone in fusion energy research. Scientists have announced that the reactor successfully superheated a plasma loop to a scorching 180 million degrees Fahrenheit (100 million degrees Celsius) for 48 seconds, setting a new world record and surpassing its own previous record of 31 seconds set in 2021.

This achievement marks a significant step forward in the pursuit of near-limitless clean energy. For over 70 years, scientists have been striving to replicate the process of nuclear fusion, which powers stars like the sun. Fusion involves fusing hydrogen atoms to create helium under extreme temperatures and pressures, producing immense energy without emitting greenhouse gases or generating long-lasting radioactive waste.

Excluding conventional hydrogen from the energy transition landscape presents challenges, but a breakthrough water-powered engine has emerged as a game-changer, setting power records and reshaping the role of hydrogen in decarbonizing the economy.

The production of hydrogen for energy purposes has garnered global interest, with a notable focus on green hydrogen as a promising energy source. Investments in hydrogen production are surging worldwide, with Spain accounting for a significant share of new hydrogen projects in 2022.

In a pioneering achievement, researchers in Japan have developed the world’s first “n-channel” diamond-based transistor, propelling us closer to processors capable of functioning at ultra-high temperatures. This breakthrough not only eliminates the necessity for direct cooling but also expands the operational range of processors to extreme environments.

By integrating diamond into a transistor—a fundamental component responsible for electrical switching between 1s and 0s when voltage is applied—the research heralds the prospect of smaller, faster, and more energy-efficient electronics. Unlike conventional components, diamond-based transistors exhibit resilience in harsh conditions, withstanding temperatures exceeding 572 degrees Fahrenheit (300 degrees Celsius) and enduring higher voltages before reaching breakdown.

In the realm of capturing micro-events unfolding at lightning speed, scientists have introduced SCARF—Swept-Coded Aperture Real-time Femtophotography. This groundbreaking camera, developed by the team at Énergie Matériaux Télécommunications at the Research Centre Institut national de la recherche scientifique (INRS) in Quebec, Canada, is designed to observe phenomena too rapid for conventional sensors to detect. From semiconductor absorption to metal alloy demagnetization, SCARF has ventured into the realm of ultrafast imaging with unprecedented accuracy.

Unlike its predecessors, SCARF operates on passive femtosecond imaging principles, enabling the T-CUP system (Trillion-frame-per-second Compressed Ultrafast Photography) to capture trillions of frames per second. Spearheaded by Professor Jinyang Liang, a trailblazer in ultrafast imaging, this breakthrough builds upon his pioneering work in 2018, laying the foundation for the current project.

In the vast spectrum of Earth’s inhabitants, humans enjoy a comfortable existence compared to some extreme organisms. While we don’t endure the vacuum of space like tardigrades or cling to scorching hydrothermal vents like extremophile bacteria, one microbe, Geobacter sulfurreducens, thrives in anaerobic environments deep within the Earth, presenting scientists with a captivating puzzle of survival.

Researchers have long been intrigued by Geobacter’s ability to flourish underground, and recent discoveries shed light on its remarkable adaptation—a microbial electric grid beneath our feet. Geobacter employs nanowires, minuscule electric “hairs,” to transfer excess electrons, connecting with minerals and other microbes to create a biological network conducive to life. Yet, the origin of these electric charges has remained a mystery—until now.

California-based inventor Peter Bevelacqua has launched a Kickstarter campaign for his latest creation, the Power Mole, designed to provide power to outdoor devices such as security cameras and decorative lights when outdoor outlets are unavailable.

The Power Mole comprises two puck-shaped components: the transmitter, affixed to the interior surface of a window pane, and the receiver, mounted on the exterior surface. The transmitter is connected to an indoor household outlet, while the receiver is USB hard-wired to the outdoor device. As an alternating electric current passes through the transmitter’s induction coil, it generates a fluctuating magnetic field that penetrates up to 30 mm of glass, inducing an alternating electric current in the receiver’s coil. A built-in rectifier then converts this AC current to DC, effectively powering the connected device.

Home automation and smart robots have transformed our kitchens, but a crucial element was missing until now: a reverse microwave to cool food instead of heating it. This groundbreaking invention, operational without electricity and emission-free, promises to revolutionize kitchen dynamics.

The absence of a reverse microwave until now can be attributed to the fundamental principles of thermal dynamics. Unlike heat, which can be readily added to objects through various methods, achieving “coolness” requires the removal of heat, dissipating it into the surroundings. The lack of a viable, electricity-free technique for rapid household cooling posed a significant challenge, with existing solutions being either small-scale projects or energy-intensive.

Machine vision, propelled by artificial intelligence (AI), has revolutionized our ability to interpret images, facilitating tasks ranging from autonomous driving to medical diagnostics. Now, researchers are pushing the boundaries of perception further by harnessing machine learning to observe human activity through walls using low-power radio frequency (RF) signals.

This innovative approach, spearheaded by scientists at institutions like Massachusetts Institute of Technology (MIT) and Washington University in St. Louis, offers a glimpse into unseen realms, enabling insights into daily activities without invasive monitoring devices or cameras.

If you’ve ever found yourself impatiently waiting for hot water to reach your faucet, you’re not alone. Beyond the frustration of wasted time, a recent report from the U.S. Department of Energy highlights the significant water wastage occurring in countless American households each year due to this common issue. However, the solution lies in a simple yet effective technology: the hot water circulation pump.

What exactly is a hot water circulation pump, and how does it work? Essentially, it’s a system that connects to your water heater and plumbing infrastructure. Typically, it includes a sensor positioned at the furthest point from the water heater, monitoring the temperature within the hot water pipes. When this sensor detects a drop in temperature, indicating that the water has cooled, the pump activates. Instead of letting the cooled water flow down the drain, it redirects it back to the water heater through either the cold water pipes or a dedicated return pipe. This continuous circulation ensures that hot water is readily available at all taps, eliminating the need to wait for it to heat up.

Konstantin Novoselov, the Nobel laureate renowned for co-creating graphene, has once again made a groundbreaking discovery that could revolutionize numerous futuristic applications, ranging from smart contact lenses to rapid disease detection. Novoselov, along with a team of scientists, has unveiled unique properties within two unconventional compounds: rhenium diselenide and rhenium disulfide, known as ReSe2 and ReS2.

These compounds belong to the same family of 2D structures as graphene, renowned for being the thinnest, strongest, and most thermally conductive material known to humanity. However, ReSe2 and ReS2 possess distinct attributes, including the ability to manipulate light in novel ways, unlocking immense technological potential.

Since at least 2009, Honda has been pioneering electric mobility solutions with its innovative uniwheel designs. From the Uni-Cub ß showcased at the 2013 Tokyo Motor Show to the latest Uni-One introduced last year in Japan, Honda continues to push the boundaries of personal mobility.

Now, the Uni-One is making its highly anticipated debut in the United States at SXSW in Austin, Texas, from March 10 as part of the Honda XR Mobility Experience. Hirokazu Hara from Honda expresses excitement about combining physical mobility with immersive digital entertainment, creating a unique multimodal experience that elevates extended reality technologies.

In a groundbreaking achievement, scientists have successfully measured the weak gravitational pull on a particle weighing just half the mass of a grain of sand. This remarkable feat, representing the most precise measurement of its kind, holds significant implications for delving into the quantum realm and potentially unraveling the mysteries of a Theory of Everything.

Gravity, one of the universe’s four fundamental forces, remains the least understood within the framework of the Standard Model of particle physics. Unlike other forces, such as electromagnetism, gravity’s behavior cannot be adequately explained by the existing model. A Theory of Everything, a long-sought-after goal in the scientific community, would require incorporating gravity at the quantum level.
