Publisher's Summary

Do you believe in the Loch Ness monster? This month's cover article, "Rulers of the Jurassic Seas" reveals an unusually large, prehistoric animal, a swimming reptile to be exact, that is fascinating for many evolutionary reasons. "The Secrets of Stardust" explores the impact the stuff that floats around in the universe has among the stars. Alzheimer's - certainly you know a family or are part of one that has suffered its terrible impact. But research is paying off. "Piecing Together Alzheimer's" examines how protein processing plays a key role in the disease. Also in this issue: a look at the appeal of gold. And, in his "Connections" column, James Burke ties together wax, greenhouses, Argentina and the king of beasts.
