Uncrackable: Scorpions and sponges inspire sustainable design
Humans are by no means alone in the search for more sustainable materials. Nature, too, has been "working" on the problem of sustainability, and it's been at it for a great deal longer. Researchers at the Weizmann Institute of Science show how design.....»»
Dark energy: Could the mysterious force we think of as constant actually vary over cosmic time?
,As I finished my Ph.D. in 1992, the universe was full of mystery—we didn't even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of these basic facts since the discovery of the cosmic.....»»
