GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, is an autonomous, solar-operated robot that carries a ground-penetrating radar to examine the layers of Greenland's ice sheet. Its findings will help scientists understand how the massive ice sheet gains and loses ice.

Architect Stefano Boeri designed Bosco Verticale, a vertical forest which will plant 900 trees on the balconies of two towers. This vegetation produces the same ecological footprint as 10,000 square meters of forest. And anyway, this way is much more fashion-forward.
