Building organs block by block with 'biological legos'

Tissue engineering has long held promise for building new organs to replace damaged livers, blood vessels and other body parts. However, one major obstacle is getting cells grown in a lab dish to form 3-D shapes instead of flat layers. Researchers have come up with a new way to overcome that challenge, by encapsulating living cells in cubes and arranging them into 3-D structures, just as a child would construct buildings out of blocks.

Computer scientist shows how evolution meets computation in new book

Nature and technology may seem worlds apart, but New York University Computer Scientist Dennis Shasha maintains that the natural world can bolster the capacity of today's most sophisticated machines. In Natural Computing: DNA, Quantum Bits, and the Future of Smart Machines, Shasha and co-author Cathy Lazere describe the work of 15 pioneers who have successfully harnessed nature's power in advancing technology.
