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.

Imagine a world so minuscule it challenges the limits of human perception — the nanoscale. To visualize this, consider shrinking a single strand of human hair a million times over. In this incredibly tiny realm, atoms and molecules govern a universe of properties and behaviors that are largely uncharted — until now.

Researchers Deepak Singh and Carsten Ullrich, along with their teams of students and postdoctoral fellows at the University of Missouri’s College of Arts and Science, have made a groundbreaking discovery: the identification of a new type of quasiparticle present in all magnetic materials, regardless of their strength or temperature. This discovery opens up a new frontier in our understanding of magnetism and could revolutionize multiple fields of technology.

Voyant Photonics has officially launched its Carbon FMCW lidar sensor, a cutting-edge solution designed to provide affordable, high-performance lidar on a chip. This new sensor, developed for applications in industrial automation, robotics, and security, offers solid-state beam steering and high-resolution, millimeter-precision detection. The company aims to push the boundaries of machine perception with a sensor that delivers advanced capabilities at a disruptive price point.

At the heart of the Carbon sensor is a silicon photonic chip that is small enough to fit on a fingernail. Despite its compact size, the Carbon sensor offers high-resolution, real-time object detection and the ability to perform static and dynamic segmentation at distances of up to 200 meters (656 feet). Voyant integrated optics directly onto the lidar photonic integrated circuit (PIC), which allows for better performance at a fraction of the cost of traditional lidar technologies.
