A team of researchers from Carnegie Mellon University has recently developed a groundbreaking method for producing large quantities of a material that could revolutionize the field of two-dimensional (2D) semiconductors. Their work, published in ACS Applied Materials & Interfaces in December 2024, promises to enhance the performance of photodetectors and pave the way for the next generation of light-sensing and multifunctional optoelectronic devices.

Semiconductors are at the heart of modern electronics, powering everything from smartphones and laptops to AI technologies. These materials control the flow of electricity by acting as a bridge between conductors (which allow electricity to flow freely) and insulators (which block it). According to Xu Zhang, assistant professor of electrical and computer engineering at Carnegie Mellon, the work done by his team is vital to advancing electronics and optoelectronics.

Supersolids, a bizarre and fascinating quantum state of matter, have now taken a new, mind-bending form: light itself. In a groundbreaking experiment, scientists have successfully transformed light into a supersolid, a development that could pave the way for advancements in quantum and photonic technologies.

Supersolids, a state previously only observed in atoms, combine the ordered structure of solids with the free-flowing properties of liquids. These extraordinary materials defy traditional classifications of matter, offering a crystalline arrangement like a solid while also exhibiting the fluid-like ability to flow without losing their shape—something that seems counterintuitive at first glance.

The Fengning Pumped Storage Power Station, located just north of Beijing, is officially up and running as of 2025. After over 11 years of construction and an investment of $2.6 billion, the station is now the largest of its kind globally, surpassing the previous record-holder in Bath County, Virginia, according to the International Hydropower Association (IHA).

Pumped-storage hydropower stations are often referred to as “water batteries” because they offer a reliable method for storing renewable energy, such as wind and solar power, which can be intermittent. By storing this excess energy, the grid experiences less stress, reducing the likelihood of blackouts. The Fengning station, for instance, supports a nearby wind and solar farm, contributing to the efficient use of clean energy.

D-Wave Quantum Inc., a Canadian company based in Vancouver specializing in quantum computing for commercial use, has made a groundbreaking achievement with its D-Wave Advantage 2 prototype annealing quantum computer. The company announced the success of solving a real-world, practical problem and validated its results through a peer-reviewed paper published in a prestigious scientific journal.

For decades, Moore’s Law has driven the rapid growth of microchip performance, with computing power doubling roughly every two years. This relentless advancement has drastically changed the landscape of computing, making devices smaller and more powerful. Despite this progress, however, many complex problems—such as climate change modeling and drug discovery—remain beyond the capabilities of even the most advanced supercomputers. In response to this challenge, quantum computing, which harnesses the principles of quantum mechanics, is poised to offer solutions to problems that could take current supercomputers years to solve.

On the morning of Saturday, March 29, the northeastern coast of North America will witness a rare and striking celestial event—a partial solar eclipse. As the sun rises, a crescent-shaped sun will appear on the eastern horizon, with the eclipse already in progress.

Thirteen U.S. states will experience the March 29 eclipse, though the intensity of the eclipse will vary depending on location. The farther northeast you go, the deeper the eclipse will be, with coastal New England offering the best views. In Maine, observers can expect up to 86% of the sun to be obscured at sunrise. New Hampshire and Massachusetts will see slightly less, with up to 57% and 55% coverage, respectively. In Boston, the eclipse will cover 43% of the sun.

Modern communication networks rely heavily on optical signals to transmit massive amounts of data. However, just like weak radio signals, these optical signals need amplification to travel long distances without degrading. For decades, erbium-doped fiber amplifiers (EDFAs) have been the go-to solution, extending transmission ranges without requiring frequent signal regeneration. While effective, EDFAs are limited by their narrow spectral range, which has hindered the expansion of optical networks.

With the increasing demand for high-speed data transmission—driven by advancements in AI accelerators, data centers, and high-performance computing—the limitations of traditional optical amplifiers are becoming more apparent. As a result, researchers are turning their attention to developing more powerful, flexible, and compact amplifiers to meet the rising data needs.

In a groundbreaking achievement, Japanese shipping company Mitsui O.S.K. Lines (MOL) has successfully produced hydrogen offshore and delivered it to Tokyo, marking a significant milestone in renewable energy. The company used its demonstration vessel, the Winz Maru, to produce green hydrogen at sea and deliver it safely to land.

The Winz Maru is equipped with an onboard plant capable of producing hydrogen from seawater, creating a highly transportable form of green hydrogen. This innovation is part of MOL’s Wind Hunter Project, which aims to develop a sustainable green hydrogen supply chain. As a global leader in green hydrogen technologies, Japan is positioning itself to play a pivotal role in the transition away from fossil fuels, with MOL at the forefront of this push.

GE’s Catalyst turboprop engine has reached a critical milestone with its recent Federal Aviation Regulation (FAR) Part 33 certification, ensuring its airworthiness and bringing it a step closer to operational deployment. This achievement is not only a technical success but also a testament to the significant innovations behind the engine, including the extensive use of 3D printing in its design. Nearly a third of the Catalyst’s internal components have been created using 3D printing technology, replacing 855 traditionally manufactured parts with just 12 3D-printed ones. The result is a lighter, more efficient engine that promises substantial cost savings in maintenance and fuel consumption.

The Catalyst turboprop engine features optimized components, including the high-temperature turbine and compressor, which have been designed for improved performance. Notably, the engine consumes 18% less fuel than comparable engines, which represents a significant financial advantage for operators. With turboprop fuel costs ranging from $250 to $600 per hour, this reduction in fuel consumption can have a considerable impact on overall operational costs.

A cutting-edge burner has been developed to improve methane combustion efficiency, featuring a unique nozzle design that directs methane flow in three distinct directions, alongside an impeller that guides gas toward the flame. This innovative configuration ensures optimal oxygen-methane mixing and enables complete combustion before external factors like crosswinds can disrupt the process. The burner’s design was made possible through a combination of machine learning, computational fluid dynamics, and additive manufacturing techniques.

Extensive testing at Southwest Research Institute’s (SwRI) indoor facility confirmed the burner’s effectiveness in simulating controlled crosswind conditions. “Even a slight crosswind drastically reduced the efficiency of most burners. We discovered that the structure and movement of the fins inside the burner played a critical role in maintaining optimal performance,” explained SwRI Principal Engineer Alex Schluneker.

Wearable technology has become a staple in modern life, but most devices are limited to smartwatches, rings, and eyewear. Now, researchers have developed a revolutionary thread-based computer that can be stitched directly into clothing, paving the way for a new era of body monitoring. This breakthrough could have significant applications in healthcare, sports, and beyond.

While devices like smartwatches are able to track heart rate, body temperature, and movement, they are often confined to monitoring specific points on the body. Meanwhile, humans generate vast amounts of data, such as heat, sound, and electrical signals, that these devices fail to capture. Recognizing this gap, a team of engineers from MIT has created a fabric-based computer capable of monitoring the body in a far more comprehensive way.

A team of physicists at the SLAC National Accelerator Laboratory in Menlo Park, California, has successfully generated the highest-current, highest-peak-power electron beams ever recorded. Their groundbreaking research, published in Physical Review Letters, marks a significant step forward in the development of high-powered electron beams, a field with potential applications ranging from fundamental science to industrial uses.

For years, scientists have pushed the boundaries of high-powered laser light, exploring its ability to split atoms and recreate conditions found on other planets. However, the SLAC team’s focus was on advancing the power of electron beams, aiming to give them similar capabilities as high-powered lasers.

Industrial technology specialists at Tohoku University have developed an innovative superelastic alloy of titanium and aluminum that combines the benefits of being both lightweight and strong, with the added bonus of flexibility.
