An international research team led by Kiel has developed a new method for the generation of controllable electrical explosions. Theoretically, it only takes 450 grams of this material to lift an elephant: "Aerographene" owes this ability to its unique structure at the nano level.

Winter temperatures in Alliance, Nebraska can drop to -20°F (the record low is -40°F/C), but retired mailman Russ Finch grows oranges in his backyard greenhouse without paying for heat. Instead, he draws on the earth's stable temperature (around 52 degrees in his region) to grow warm weather produce- citrus, figs, pomegranates - in the snow.
