中国研究人员上月发布了一种使用超导量子干涉仪（SQUID）的重力探测器，其精度世界领先，且体积紧凑，可在实验室外使用。该设备据中国科学院网站报道，能测量微小重力变化，用于探测物体，并可能扩展军事应用。
中国研究人员开发的重力探测器利用SQUID技术，通过测量微小重力变化来探测物体。该设备据中国科学院（CAS）网站报道，将重力梯度测量噪声——如地震振动等外部干扰——降低到仅次于千米级引力波探测器的水平。
这款探测器体积相当于一个办公室隔间，而美国激光干涉引力波天文台（LIGO）等大型设备则使用相距4公里（2.5英里）的镜子研究宇宙。该紧凑设计使其适用于野外环境。
开发团队表示，该仪器可用于科学研究和探测地下资源。同时，它使中国更接近探测巡逻核潜艇的能力，如美国俄亥俄级核潜艇。现有潜艇探测方法包括声纳、磁异常探测和雷达，但这些均可被规避，而重力无法掩盖。
CAS报告强调，该技术在噪声抑制方面的进步具有世界领先精度，可能扩展军事应用。

Physicists at MIT have developed a new microscope using terahertz light to directly observe hidden quantum vibrations inside a superconducting material for the first time. The device compresses terahertz light to overcome its wavelength limitations, revealing frictionless electron flows in BSCCO. This breakthrough could advance understanding of superconductivity and terahertz-based communications.

Scientists have developed a method to monitor space debris reentering Earth's atmosphere using existing earthquake sensors. By detecting sonic booms from the debris, the technique provides precise tracking of its path and potential landing sites. This approach was tested on debris from China's Shenzhou-15 spacecraft.
Scientists have developed a light-based sensor that can identify tiny amounts of cancer biomarkers in blood samples, potentially enabling earlier detection than traditional scans. The technology combines DNA nanostructures, CRISPR, and quantum dots to produce a clear signal from just a few molecules. Tests on lung cancer patient serum showed promising results at sub-attomolar levels.
Astronomers have identified what appears to be a massive cloud of dark matter roughly 3,000 light years from our solar system. Using pulsar observations, a team led by Sukanya Chakrabarti detected gravitational effects suggesting an object 60 million times the sun's mass. This could be the first such sub-halo found in the Milky Way.

Scientists in Australia have developed the largest quantum simulator to date, using 15,000 qubits to model exotic quantum materials. This device, known as Quantum Twins, could help optimize superconductors and other advanced substances. Built by embedding phosphorus atoms in silicon chips, it offers unprecedented control over electron properties.
