Up To Date | Mosquitoes, robots, pupils, beavers, and Earth’s crust

This week: A new study showing how you can, as a way to control their population, change blood-drinking female mosquitoes to male, non-biting mosquitoes by changing just one gene; research into new ways for robots to grab things; a study showing the ways in which the pupils of people who have PTSD react differently than others, even in emotionally-neutral situations; beavers in Alaska are working overtime in the Arctic tundra as a result of climate change and possibly damaging the ecosystem; and research examining how the Earth’s crust cracked in the first place.
