Suns Voc current-voltage testing adapted for system-wide use — ScienceDaily

A new system for measuring solar performance over the long term in scalable photovoltaic systems, developed by Arizona State University researchers, represents a breakthrough in the cost and longevity of interconnected power delivery. When solar cells are developed, they are “current-voltage” tested in the lab before they are deployed in panels and systems outdoors. Once […]

Archaeology: Neanderthal thumbs better adapted to holding tools with handles

Neanderthal thumbs were better adapted to holding tools in the same way that we hold a hammer, according to a paper published in Scientific Reports. The findings suggest that Neanderthals may have found precision grips — where objects are held between the tip of the finger and thumb — more challenging than power ‘squeeze’ grips, […]
