Two, six, many - physicists observe the emergence of collective behaviour

Phase transitions describe dramatic changes in properties of a macroscopic system - like the transition from a liquid to a gas. Starting from individual ultracold atoms, physicists were able to observe the emergence of such a transition with an increasing number of particles.

Researchers find a better way to design metal alloys

System uses machine learning to analyze boundaries between crystal grains, allowing for selection of desired properties in a new metal.

Researchers create MRI-like technique for imaging magnetic waves in ultrathin magnets

The MRI system made by the researchers makes use of a special lattice defect in the crystal structure of diamonds. This defect - known as nitrogen-vacancy centre - enables high-resolution imaging of the magnetic structure of a sample.

Nanosensors embedded in living plants detect arsenic

Researchers have developed a living plant-based sensor that can in real-time detect and monitor levels of arsenic, a highly toxic heavy metal, in the soil.

Faraday fabrics with MXene coatings?

MXene-coated fabric could contain electronic interference in wearable devices.

Artificial visual system of record-low energy consumption for the next generation of AI

Researchers have built an ultralow-power consumption artificial visual system to mimic the human brain, which successfully performed data-intensive cognitive tasks. Their experiment results could provide a promising device system for the next generation of artificial intelligence (AI) applications.

Trapping nanoparticles with optical tweezers

By exploiting a particular property of light diffraction at the interface between a glass and a liquid, researchers have demonstrated optical tweezers capable of trapping nanoparticles.
