Researchers develop flexible fiber material for self-powered health-monitoring sensors

Could clothing monitor a person’s health in real time, because the clothing itself would be a self-powered sensor? A new material created through electrospinning, which is a process that draws out fibers using electricity, brings this possibility one step closer.

A team led by researchers at Penn State has developed a new fabrication approach that optimizes the internal structure of electrospun fibers to improve their performance in electronic applications. The team has published its findings in the Journal of Applied Physics.

This novel electrospinning approach could open the door to more efficient, flexible and scalable electronics for wearable sensors, health monitoring and sustainable energy harvesting, according to Guanchun Rui, a visiting postdoctoral student in the Department of Electrical Engineering and the Materials Research Institute and co-lead author of the study.

Chinese Scientists Develop Breakthrough Catalyst for Clean Propane Conversion

Scientists have pioneered a water- and light-driven method for converting propane at near-room temperature, opening the door to sustainable, low-energy catalysis. Propane dehydrogenation (PDH) is a chemical process that requires a large input of heat, typically needing temperatures above 600°C wh

Nearly three-quarters of solar and wind projects are being built in China

China is rapidly scaling up its solar and wind energy infrastructure, accounting for nearly three-quarters of all utility-scale projects currently under construction worldwide, according to a new report from the Global Energy Monitor (GEM). With 510 gigawatts (GW) already under construction and a total pipeline of over 1.3 terawatts (TW), China is consolidating its position as a dominant force in the global energy transition.

This acceleration follows years of sustained growth. As of early 2025, China’s operating solar and wind capacity has reached 1.4 TW—equivalent to 44% of the global total and more than the combined capacity of the European Union, United States, and India. In the first quarter of this year, wind and solar supplied 22.5% of the country’s electricity, overtaking thermal power capacity for the first time.

The majority of China’s new capacity is coming from centralized utility-scale projects, particularly in northern and western regions such as Xinjiang and Inner Mongolia, which host nearly 40% of the country’s planned solar and wind capacity. In 2024 alone, China added 278 GW of solar and 46 GW of wind.

Lunar soil could support life on the Moon, say scientists

Scientists have developed a technology that may help humans survive on the moon. In a study published in the journal Joule, researchers extracted water from lunar soil and used it to convert carbon dioxide into oxygen and chemicals for fuel—potentially opening new doors for future deep space exploration by mitigating the need to transport essential resources like water and fuel all the way from Earth.

“We never fully imagined the ‘magic’ that the lunar soil possessed,” said Lu Wang of the Chinese University of Hong Kong, Shenzhen.

“The biggest surprise for us was the tangible success of this integrated approach. The one-step integration of lunar H2O extraction and photothermal CO2 catalysis could enhance energy utilization efficiency and decrease the cost and complexity of infrastructure development.”

Marathon Fusion claims it can turn mercury into gold while creating clean energy

A startup energy company, called Marathon Fusion, may soon be living out the dream of alchemists from the Middle Ages. In a recently released paper posted to the arXiv preprint server, the company outlines a method to turn an isotope of mercury, 198Hg, into 197Au, the most stable form of gold.

Study finds cell cytoskeleton mimics critical phenomena seen in earthquakes and metals

Prof. Michael Murrell’s group (lead author Zachary Gao Sun, graduate student in physics) in collaboration with Prof. Garegin Papoian’s group from the University of Maryland at College Park has found critical phenomena (self-organized criticality) that are reminiscent of the earthquakes and avalanches inside the cell cytoskeleton through self-organization of purified protein components.

In a groundbreaking discovery, researchers have found that the cell’s cytoskeleton—the mechanical machinery of the cell—behaves much like Earth’s crust, constantly regulating how it dissipates energy and transmits information. This self-regulating behavior enables cells to carry out complex processes such as migration and division with remarkable precision.

Even more striking, the study draws parallels between the behavior of microscopic cellular structures and massive celestial bodies, suggesting that the principles of criticality—where systems naturally tune themselves to the brink of transformation—may be universal across vastly different scales of nature.

RGB multiplexer based on lithium niobate enables faster, more efficient light modulation for laser beam scanning

As technology advances, photonic systems are gaining ground over traditional electronics, using light to transmit and process information more efficiently. One such optical system is laser beam scanning (LBS), where laser beams are rapidly steered to scan, sense, or display information.

This technology is used in applications ranging from barcode scanners at grocery stores to laser projectors in light shows. To process a wider range of signals or enable full-color output, these systems utilize multiplexers that merge the red, green, and blue (RGB) laser beams into a single beam.

Traditionally, this was achieved by directly modulating each laser, turning them on and off to control the output. However, this approach is relatively slow and energy intensive. A recent study by researchers at the TDK Corporation (Japan) reports the development of a faster and more energy-efficient RGB multiplexer based on thin-film (TFLN).

New device converts plastic waste into fuel using catalyst-free pyrolysis

As tons of plastic waste continue to build up in landfills every day, Yale researchers have developed a way to convert this waste into fuels and other valuable products efficiently and cheaply. The results are published in Nature Chemical Engineering.

Specifically, the researchers are using a method known as pyrolysis, a process of using heat in the absence of oxygen to molecularly break materials down. In this case, it’s used to break plastics down to the components that produce fuels and other products. The study was led by Yale Engineering professors Liangbing Hu and Shu Hu, both members of the Center for Materials Innovation and Yale Energy Sciences Institute.

Conventional methods of pyrolysis often use a to speed up the and achieve a high yield, but it’s a method that comes with significant limitations.

This MIT spinout’s electric bricks store heat hotter than lava

MIT spinout Electrified Thermal Solutions has inked a deal with HWI, a member of Calderys and one of the biggest refractory suppliers in the US, to make electrically conductive firebricks – electric bricks, or E-bricks – that store and deliver extreme heat using renewable electricity.

The innovative partnership is all about scaling up Electrified Thermal’s Joule Hive Thermal Battery, which conducts clean power and stores it as heat up to a scorching 1,800C (3,275F). That’s hot enough to drive even the most energy-hungry industrial processes like steelmaking, glass, or cement production.

The E-bricks enable factories to ditch fossil fuels and run on renewables without sacrificing performance or reliability, and at a lower cost.

Research shows how sulfate ions increase the lifespan, performance of aqueous batteries

Scientists at King Abdullah University of Science and Technology (KAUST) have uncovered a critical molecular cause keeping aqueous rechargeable batteries from becoming a safer, economical option for sustainable energy storage.

Their findings, published in Science Advances, reveal how water compromises battery life and performance and how the addition of affordable salts—such as zinc sulfate—mitigates this issue, even increasing the battery lifespan by more than ten times.

One of the key determinants of the lifespan of a battery—aqueous or otherwise—is the . Chemical reactions at the anode generate and store the battery’s energy. However, parasitic degrade the anode, compromising the battery lifespan.
