Skin-inspired coating that's as hard as teeth and can heal itself

Self-healing smart coatings could someday make scratches on cell phones a thing of the past. But researchers often have to compromise between strength and the ability to self-repair when developing these materials. Now, one group reports the development of a smart coating that is as hard as tooth enamel on the outside but can heal itself like skin can.

BA or DA? Decoding syllables to show the limits of artificial intelligence

By recording brain activity during a simple task, neuroscientists show that the brain does not necessarily use the regions of the brain identified by machine learning to perform a task. Above all, these regions reflect the mental associations related to this task. While machine learning is thus effective for decoding mental activity, it is not necessarily effective for understanding the specific information processing mechanisms in the brain.

Precisely tailoring the dynamics of upconversion luminescence

Researchers have significantly improved the fundamental understanding of photon upconversion in nanoparticles. Through the collaborative approach of advanced spectroscopy and theoretical modelling they were able to establish that the migration of excitation energy greatly affects the upconversion dynamics. The researchers describe how 'dopant ions spatially separated' (DISS) nanostructures can be used for tailoring the upconversion dynamics.

Certain bacteria produce tiny gold nuggets by digesting toxic metals

High concentrations of heavy metals, like copper and gold, are toxic for most living creatures. This is not the case for the bacterium C. metallidurans, which has found a way to extract valuable trace elements from a compound of heavy metals without poisoning itself. One interesting side-effect: the formation of tiny gold nuggets.
