Beneath the Ice in Antarctica
To outer space and the deep ocean, add “beneath the ice” to the list of rarely charted frontiers of science exploration. There have been very few expeditions where robots dived beneath polar ice shelves to characterize and measure them. UC Davis engineering professor Alexander Forrest recently returned from one of them.
This solar-powered device can squeeze water out of thin air
You can’t squeeze blood from a stone, but you can squeeze water from thin air — even in the driest areas of the world.
The new water harvester is made of metal organic framework crystals pressed into a thin sheet of copper metal and placed between a solar absorber (above) and a condenser plate (below).
