Dimensions of Mind Perception
Heather M. Gray, Kurt Gray, and Daniel M. Wegner
Science 2 February 2007: 619.
In a Web-based survey, people conclude that anything that has feelings (such as hunger or pride) and the ability to act (such as communicating or showing self-restraint) possesses a mind.

Composite Materials with Viscoelastic Stiffness Greater Than Diamond
T. Jaglinski, D. Kochmann, D. Stone, and R. S. Lakes
Science 2 February 2007: 620-622.
Adding barium titanate to tin produces a composite material that is stiffer than diamond, because the trapped inclusions have negative compressibility.

Coupling Coherence Distinguishes Structure Sensitivity in Protein Electron Transfer
Tatiana R. Prytkova, Igor V. Kurnikov, and David N. Beratan
Science 2 February 2007: 622-625.
Average rates of electron tunneling in proteins, which seem to reflect the distance from donor to acceptor, are actually produced by multiple tunneling pathways.

Thymine Dimerization in DNA Is an Ultrafast Photoreaction
Wolfgang J. Schreier, Tobias E. Schrader, Florian O. Koller, Peter Gilch, Carlos E. Crespo-Hernández, Vijay N. Swaminathan, Thomas Carell, Wolfgang Zinth, and Bern Kohler
Science 2 February 2007: 625-629.
Because spectroscopy indicates that ultraviolet light damages DNA within 1 picosecond, the damage depends on the DNA conformation just before it absorbs the light.

Single Photon-Induced Symmetry Breaking of H2 Dissociation
F. Martín, J. Fernández, T. Havermeier, L. Foucar, Th. Weber, K. Kreidi, M. Schöffler, L. Schmidt, T. Jahnke, O. Jagutzki, A. Czasch, E. P. Benis, T. Osipov, A. L. Landers, A. Belkacem, M. H. Prior, H. Schmidt-Böcking, C. L. Cocke, and R. Dörner
Science 2 February 2007: 629-633.
When light dissociates hydrogen gas, two dissociation pathways of opposite parity entangle, leading to correlations in the directions followed by the resulting proton, electron, and atom.
