Line Between Quantum And Classical Worlds Is At Scale Of Hydrogen Mole
Where do the realms of quantum mechanics and classical physics begin to overlap? It's a long-argued question of philosophical interest and practical importance. Now the world's smallest double slit experiment, performed at Lawrence Berkeley National Laboratory's Advanced Light Source and using as "slits"the two proton nuclei of a hydrogen molecule, has shown that quantum particles start behaving in a classical way on a scale as small as a single hydrogen molecule.

Genetic Surprise: Mobile Genes Found To Pressure Species Formation
Biologists at the University of Rochester have discovered that an old and relatively unpopular theory about how a single species can split in two turns out to be accurate after all, and acting in nature. The finding, reported in today's issue of Science, reveals that scientists must reassess the forces involved in the origin of species. The beginnings of speciation, suggests the paper, can be triggered by genes that change their locations in a genome.

Simple Intervention Encourages Sun Protection Behaviors
Photographs that reveal hidden skin damage from ultraviolet (UV) exposure from the sun, combined with information on sunless tanning alternatives, was effective in encouraging sun protection behaviors in a small group of college students, according to an article in the March issue of the Archives of Dermatology, one of the JAMA/Archives journals.

Cloud Research Indicates A Faster Pace For Stratospheric Ozone Destruc
The greenhouse effect may be happening much faster than previously believed, scientists in Finland and the United States report. The University of Helsinki's Anatoli Bogdan and colleagues, who include chemistry Nobel laureate Mario J. Molina, reached that conclusion from laboratory studies of the low-temperature thin and subvisible cirrus (SVC) clouds that have such a powerful impact on climate.
