New research from Memorial Sloan Kettering Cancer Center (MSK) investigates whether introducing new mutations could make immunotherapy more effective against some cancers; shows that people in their 90s who underwent lung cancer surgery had positive outcomes; shares lessons on the responsible governance of artificial intelligence in oncology; studies AI-assisted biomarker assessment in lung cancer; and demonstrates a cancer-trained large language model has strong predictive value.

Led by Assistant Professor Kou Li, a research group in Chuo University, Japan, has developed chemically enriched photo-thermoelectric (PTE) imagers using semiconducting carbon nanotube (CNT) films, resulting in the achievement of enhanced response intensity and noise reduction, that enables efficient remote and on-site inspections, according to a recent paper publication in Communications Materials. CNT film-based PTE imagers are crucial for multimodal non-destructive inspection, but conventional device design strategies have faced challenges in achieving high response intensity for wireless data logging.

　CNT film-based PTE imagers enable functional electromagnetic-wave monitoring, potentially facilitating multimodal non-destructive inspection device usage. The CNT film compositions govern the fundamental device performance, and satisfying high PTE conversion efficiency (higher response and lower noise) is essential for sensitive operations. Although typical sensitive design focuses on minimising noise, the associated levelling-off response intensity (up to a few millivolts) induces technical limitations in device operations. These issues include mismatching for coupling with compact wireless circuits, which are indispensable for on-site inspection applications and require high-intensity responses at least a few millivolt orders. This work develops chemically enriched PTE imagers comprising semiconducting CNT (semi-CNT) films. While semi-CNTs provide greater intensity thermoelectric responses than semi-metal mixture compositions in the conventional PTE device, the presented imager employs p-/n-type chemical carrier doping to relax inherent significant bottlenecking noise. Such doping enhances material properties for PTE conversion with semi-CNTs up to 4,060 times. The imager satisfies similar performances to conventional CNT film devices, including ultrabroadband sensitive photo-detection (with minimum noise sensitivity of 5 pWHz^−1/2) under repeatedly deformable configurations, and advantageously exhibits response signal intensity exceeding a few–tens of millivolts. These features enable remote on-site non-destructive PTE imaging inspection with palm-sized wireless circuits.

For thousands of years, humans have combined metals to collectively harness properties found in individual components, producing such practical materials as bronze, brass and, more recently, steel. However, predicting the exact microstructures underpinning these alloys to understand how specific properties of the constituent materials may manifest across scales is still a complex mystery researchers are working to solve. Now, thanks to a team based in Japan, that work could take minutes instead of years.

Analog repeaters dramatically enhance millimeter-wave (mmWave) coverage in mobile networks by overcoming signal blockage, report researchers from Science Tokyo. As demonstrated in a field experiment at Ookayama Campus, low-cost repeaters connected either wirelessly or via optical fiber offer a promising solution for 5G and 6G networks. Both configurations achieved over 1 Gbps throughput and enhanced mmWave signal stability, showing strong potential for practical deployment in urban and high-traffic areas.
