A research team led by Prof. Wan Yinhua at the Institute of Process Engineering (IPE), Chinese Academy of Sciences, has developed a groundbreaking mix-charged nanofiltration (NF) membrane that promises to revolutionize wastewater treatment, especially for high-salinity organic waste. This novel membrane, featuring a horizontal charge distribution, exhibits exceptional performance in salt permeation, organic matter retention, and antifouling properties, making it an ideal solution for treating complex, high-salinity wastewater.

The findings were published in Environmental Science & Technology on January 7, shedding light on a new approach to overcoming the limitations of traditional NF membranes in wastewater treatment.

Imagine a device that could identify mechanical damage in apples before bruising appears, detect diseases through a patient’s breath, monitor food freshness in real time across entire supply chains, and even sniff out hazardous gases in industrial settings—all using technology already found in your smartphone. Researchers at the Norwegian University of Science and Technology (NTNU) have developed such a device: a groundbreaking electronic nose that uses a single sensor to perform tasks that typically require hundreds of sensors. This innovative technology, known as the “Ant-nose,” could revolutionize industries ranging from food safety to environmental monitoring, offering a simpler and more affordable alternative to existing systems.

The Ant-nose uses a familiar principle—antenna technology, the same technology that powers wireless communication in devices like smartphones and computers—to create an artificial sense of smell. Unlike traditional electronic noses, which often require large arrays of specialized sensors, the Ant-nose achieves its remarkable sensitivity with a single antenna and a single type of coating. This simplicity dramatically reduces both cost and power consumption while maintaining high performance.

As part of NASA’s Artemis campaign, a cutting-edge X-ray imager, the Lunar Environment Heliospheric X-ray Imager (LEXI), is heading to the Moon to capture the first global images of Earth’s magnetic field, which protects our planet from harmful solar radiation. LEXI is one of 10 scientific payloads onboard the upcoming lunar mission, set to launch from Kennedy Space Center in Florida no earlier than mid-January. The payload will ride aboard Firefly Aerospace’s Blue Ghost Lander under NASA’s Commercial Lunar Payload Services (CLPS) initiative.

LEXI’s primary mission is to support NASA’s understanding of how Earth’s magnetosphere—its magnetic shield—responds to space weather, which is driven by solar activity. By taking detailed X-ray images of this protective barrier, the instrument will provide insights into the dynamic processes that shape our planet’s interaction with the solar wind and other cosmic forces.
