An octopus likes to be wined and dined during sex. A study looking at the larger Pacific striped octopus shows that, unlike most octopuses, the male and female face each other when mating – a pose that may allow them to feed together at the same time (PLoS One, DOI: 10.1371/journal.pone.0134152). Now glasses can hide you from prying eyes. A team at Japan's National Institute of Informatics has developed a pair of glasses whose patterning foils face recognition software. The Privacy Visor is expected to go on sale in June 2016 for about $240.
