Infrared heavy metal-free quantum dots provide sensitive and fast sensors for eye-catching rider applications
Ag2te colloidal quantum dot SWIR photodiode on the left and solution-treated AG2TE quantum dots on the right. Credit: Jordi Cortés, ICFO. The frequency regime in shortwave infrared (SWIR) has very unique properties ideal for some applications, such as not easily affected by atmospheric scattering and being “eye guardian”. These include photodetection and range (LIDAR), methods for determining range and distance…

Researchers develop glass sensors for Einstein telescopes
Jena researchers manufacture highly sensitive resonators made entirely of glass for the vibration sensors of the Einstein telescope. Credit: Fraunhofer IOF Starting in 2035, Einstein Telescope will be able to study gravitational waves with unprecedented accuracy. For telescopes, Jena researchers produced the first highly sensitive sensor made of glass. Gravitational waves are space-time distortions caused by extreme astrophysical events such…

Quantum Entanglement Sensors can test quantum gravity
Supreme-GQ artist concept. Credit: S. Shahriar/NASA When you ask most physicists what is the most frustrating problem in modern physics, they will say the contradiction between general theory of relativity and quantum mechanics. That contradiction has been a thorn on the part of the physics community for decades. There have been some advances in potential theories that can modify the…

Scientists use distant sensors to monitor American Samoa earthquake flocks
Credit: Earthquake Records (2025). doi:10.1785/0320240040 From late July to October 2022, residents of the Manua Islands in Samoa, USA, had their planet shaking several times a day, causing concerns about an imminent volcanic eruption or tsunami. Nothing appeared in the area’s earthquake catalogues as the islands lacked earthquake monitoring networks that could assist seismologists who sway in searching for sources…

Thousands of small, time sensors that secure time can collectively map chemical concentration in a narrow tube.
The human intestinal system (A) can be represented as a series of plugflow reaction devices (B), a model that describes a chemical reaction in the flowing cylindrical system. Time recognition particles (C) pass through the plugflow system and detect interest chemicals known as analysis. Credit: Manion et al. , 2025. A diagram made partially in a violence. When synthesizing chemicals,…

Detecting disease with a single molecule: Nanopore-based sensors could transform diagnostics
The sensor is a glass tube whose tip is melted into a sharp needle-like structure that is immersed in a liquid containing molecules. Credit: Kevin Freedman/ImageFX/UCR Scientists at the University of California, Riverside have developed a nanopore-based tool that can diagnose diseases much faster and more accurately than current tests by capturing signals from individual molecules. The molecules that scientists…
