Superwood

University of Maryland spinout InventWood have developed a new treated wood that has 50% more tensile strength than steel and a strength to weight ratio that is 10 times better than steel. The company uses chemicals to change the molecular structure of the wood, and then increases the hydrogen bonds between cellulose molecules using compression.

Audubon published an interesting piece about how researchers are using birds as research assistants, to gather data and/or infer data from their movements and habits. Examples include checking the type of vomit thrown up by western gulls to track the movement of whales, and putting sensors on cormorants to track sea level depth changes.
