https://phys.org/news/2019-02-bees-brains-basic-math.html
Building on their finding honeybees understand the concept of zero, Australian and French researchers discovered bees can perform addition and subtraction. The small brains of bees can manage numbers and rules. They can recognize colors as symbolic representations of addition and subtraction then use this information to solve problems.
Video games could be a short-term answer to science’s gender problem
A woman who grew up loving to play Zelda and Mario wondered if her love of games led to her love of physics and engineering in school. She discovered many girls who play lots of video games go on to complete a science, technology, engineering or math (STEM) undergraduate degree than non-gamers.
Girls who played nine plus hours of video games a week were 3.3 times more likely to study STEM. This accounted for their socio-economic background, ethnicity, past performance and how good they felt they were at their chosen subject. Video game-playing boys, meanwhile, were only 1.5 times as likely to take up a STEM degree.
