What if big data could help you see the future and prevent your mobile phone from breaking before it happened? Scientists at the University of Sydney have demonstrated the ability to “see” the future of quantum systems, and used that knowledge to preempt their demise, in a major achievement that could help bring the strange and powerful world of quantum technology closer to reality...

Nanoparticles containing 3 different layers of material can help to boost the performance of a zinc-air battery, A*STAR researchers have found. Zinc-air batteries are cheap, have a high energy density, and last for a very long time. Their use of a water-based electrolyte makes them safer than other batteries, so they’re often found in medical applications, such as hearing aids and heart monitoring devices.

The battery’s negative electrode contains zinc metal, which gives up electrons when it reacts with hydroxide ions in the electrolyte...

Multiplexed image analysis with HySP is faster and less expensive than other methods. Image courtesy of Francesco Cutrale.

A new image analysis technique makes it easier for scientists to quickly find and track important biological molecules including tell-tale signs of disease. Called “Hyper-Spectral Phasor” analysis, or HySP, it could even be useful for diagnosing and monitoring diseases by using cell phone images. It is much faster and far less expensive than current techniques. Through the new imaging technology, researchers use fluorescent imaging to locate proteins and other molecules in cells and tissues. It works by tagging the molecules with dyes that glow under certain kinds of light – the same principle behind so-called “black light” images.

Fluorescent imaging can help scientis...

Semiconductors, which are the very basic components of electronic devices, have improved our lives in many ways. They can be found in lighting, displays, solar modules and microprocessors that are installed in almost all modern day devices, from mobile phones, washing machines, and cars, to the emerging Internet of Things. To innovate devices with better functionality and energy efficiency, researchers are constantly looking for better ways to make them, in particular from earth-abundant materials using eco-friendly processes...
