Detector

Using nanoparticles, researchers have created a sensor that selectively detects levels of cortisol, a well-known stress biomarker. Their cheap and easily reproducible device brings us a step closer to stress testing from the comfort of home.

A novel device can detect the COVID-19 virus in one minute using just a couple of breaths of exhaled air. The device could revolutionize the testing process, especially at large-scale social gatherings like concerts or sporting events.

The humble X-ray may have received a long-overdue upgrade thanks to the development of a highly sensitive, printable X-ray detector that can operate over a wide range of energy levels, with potential in a wide range of real-world applications.

The first dark matter detector in the Southern Hemisphere has been officially opened. The Stawell Underground Physics Laboratory (SUPL) is built in a disused gold mine in Australia, giving it a unique position on the globe for detecting dark matter.

The world’s most sensitive dark matter detector is ready to tackle one of the most perplexing mysteries of the universe. Over 50 times more sensitive than others, LUX-ZEPLIN lurks quietly a mile underground, waiting for these hypothetical particles.

Borexino, a huge underground particle detector in Italy, has picked up a never-before-seen type of neutrino coming from the Sun. These neutrinos confirm a 90-year-old hypothesis and complete our picture of the fusion cycle of the Sun and other stars.

Scientists have so far been unable to detect dark matter. But a new detector design, using an array of billions of tiny pendulums, could finally break the silence by searching for the effects of dark matter’s incredibly strong gravitational pull.

Scientists at North Carolina State University have developed a technique that could allow bricks and other common building materials to act as "cameras" that reveal the location and distribution of radioactive materials once in their vicinity.

Although smartphones perform many tasks on their own, they're also able to make devices such as drones, robots and cameras cheaper and/or more capable by acting as their "brains." One of the latest gadgets to receive such a treatment is the humble – and potentially treasure-finding – metal detector.

​Cosmic rays are raining down over Earth every day, but you’d never know unless you had the right tools. Those tools mostly take the form of bulky, expensive lab equipment, but thanks to an MIT team, you can now build your own detector for US$100 – small enough to take on a plane or the subway.​

Joseph Wang and colleagues at the University of California, San Diego have created a ring with a difference. It detects chemical and biological threats in the wearer's environment.​

A 20-month experiment conducted a mile underground has failed to detect dark matter particles directly, but the results are still giving scientists important clues on the nature of this elusive substance.
