Placing your foot accurately is a complicated process. If something moves where you plan to place your foot then you can adjust your step while your foot is swinging through. Experts thought previously that if nothing changed in the path, or in your plans, then the place where your foot will land is fixed before it even leaves the ground. In this case, you would make no use of immediate visual information during each step.
Researchers monitored the accuracy with which subjects could step onto a target. In 50% of the attempts they blocked subjects’ vision just at the point when they were lifting their foot off the ground. On the occasions when vision was blocked, the subjects were less able to step accurately on the target.
“Because vision was blocked only after the foot had left the floor, this research shows that we use visual information to adjust our footfall while our foot is moving forwards – it is not simply predetermined at the beginning of the step,” says Dr Raymond Reynolds, who along with Dr Brian Day conducted the work at the Institute of Neurology, Queen Square, London. The research is published this week in the Journal of Physiology.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
