Urine can reveal a lot about a person's health. But physicians don't currently have a convenient or fast way of tracking the concentration of important compounds in their patients' urine. Now, researchers have designed a flexible sensor that fits in a diaper, measures multiple components in urine...

Researchers have shown it is possible to perform artificial intelligence using tiny nanomagnets that interact like neurons in the brain....

As a result of corrosion, copper and silver release positively charged ions into their environment, which are harmful to bacteria in several ways and prevent their growth or kill them completely. This effect has long been exploited, for example by coating implants with these metals to prevent...

Researchers use silicon nanoparticles to help visualize the coalescence of quantized vortices that occur in superfluid helium, which can help improve our understanding of quantum fluids and materials, including superconductors. ...

Scientists from the Graduate School of Engineering Science at Osaka University have shown how silicon nanoparticles can become trapped inside the vortices that form inside superfluid helium. This work opens up new possibilities in optical research for other quantum properties of superfluid helium,...

Since graphene was first isolated and characterized in the early 2000s, researchers have been exploring ways to use this atomically thin nanomaterial because of its unique properties such as high tensile strength and conductivity....

High-entropy nanoalloys (HENA) have widespread applications in materials science and applied physics. However, their synthesis is challenging due to slow kinetics that cause phase segregation, sophisticated pretreatment of precursors, and inert conditions. In a new report now published in Science...

Engineers have developed a high-performance nanowire catalyst that pulls ammonia and solid ammonia (fertilizer) from nitrate, a common contaminant in industrial wastewater and polluted groundwater. ...

A dash of ruthenium atoms on a mesh of copper nanowires could be one step toward a revolution in the global ammonia industry that also helps the environment....

We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the proteins encoded by it. Fast forward to modern day humans: science has...
