To probe the drug's effect on memory, Sorg's
team placed pond snails in two pools of low - oxygen water, one of which was laced with meth.
Then, the
team placed the snails in an uncrowded beaker containing water with a normal level of calcium and trained the snails to not come up for air — no big deal for
pond snails, who can also get oxygen by absorbing it underwater through their skin.
To find out how climate change will affect the overall survival of Arctic mosquitoes (Aedes nigripes), a
team of researchers
placed mosquito larvae taken from
ponds in western Greenland into chambers with temperatures ranging from 4 °C to 19 °C, simulating temperatures measured in the
ponds during mosquito development, and then timed how long it took for the adults to emerge.
