Mathematicians solve 140-year-old Boltzmann equation

Two University of Pennsylvania mathematicians have found solutions to a 140-year-old, 7-dimensional equation that were not known to exist for more than a century despite its widespread use in modeling the behavior of gases.

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.

Spiders at the nanoscale: Molecules that behave like robots

A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular 'robot' made out of DNA to start, move, turn, and stop while following a DNA track.
