Bees communicate by making special dance movements. When a new source of pollen has been found, a bee will spread the good news by doing a special dance. For instance, if a bee dances in a circular motion then it means that food can be found nearby.
Burning backwards
Burning backwards At the Southern Illinois University, U.S.A., a
process to effectively reverse the chemistry of burning has been
invented. This process could help recycle carbon dioxide released
by burning, rather than letting it flow into the atmosphere. The
process uses carbon dioxide to produce methanol, a clean burning
fuel used to power cars. This fuel could be produced and used
without adding to the greenhouse effect. 29 JANUARY 2000, P. 15
