Want more efficient simulators? Store time in a quantum superposition
Computer models of systems such as a city's traffic flow or neural firing in the brain tends to use up a lot of memory. But a new approach with quantum simulators could significantly cut that memory use by taking a quantum approach to time, suggest researchers in Singapore. (2018-03-02)

Memory overload? That's when the eyes step in eyes
When you want to remember a phone number, you likely repeat the digits to yourself again and again. We unknowingly do something similar with our eyes to help us recall what we see and we do this more often when we're older, according to recently published findings in the Journal of Experimental Psychology: Human Perception and Performance.

Deep-brain exploration with nanomaterial
Studying deep brain tissues noninvasively is difficult. Now RIKEN scientists in Japan have developed a way to send light deep into the brain without invasive optical fibers. The method uses infrared light outside the head to activate upconversion nanoparticles (UCNPs). When these nanoparticles absorb near-infrared laser light, they emit visible photons to deep areas in the brain, allowing remote optogenetic stimulation or inhibition of neurons in the brain.
