Cover
A montage showing three views of a
5-millimeter-long juvenile medaka, with the nervous system imaged with
a digital scanned laser light sheet fluorescence microscope. This
technique has been used to reconstruct embryogenesis in zebrafish.

Minnesota Ecologist Pushes Prairie Biofuels
David Tilman wants to mix it up by growing native grasses for energy. Many agronomists disagree.
A Bunch of Trouble
The banana is endangered and
largely ignored by funding agencies, researchers, and breeders. But
things might finally be going its way.
Reconstruction of Zebrafish Early Embryonic Development by Scanned Light Sheet Microscopy
Digitized
tracking of each cell during the first 24 hours of zebrafish
development reveals how the body axis and germ layer are formed and
provides a community resource.
