Soaking Up Rays
Although light shines through body parts of a primitive marine sponge much as it does through sophisticated optical fibers for telecommunications, scientists differ on whether sponges hold clues to better fibers for humankind.

Busting the Gut Busters
Scientists are uncovering a cache of specialized weaponry used by bacteria that can spear holes in the intestine, perforate it, force it to change shape, and then spew toxins that attack other organs.

Insects in the wind lead to less power
A previously puzzling pattern of power loss in wind turbines results from coatings of insects that were smashed by the blades during low winds.

Turning magnetic resonance inside out
A new method of manipulating magnetic signals makes it possible to gather useful information about a chemical sample—or perhaps one day a person—without often-claustrophobic confinement inside a magnetic coil.

When Galaxies Collide
Dramatic images from the largest computer simulation ever of a plausible collision between the Milky Way and Andromeda galaxies highlight this report from the National Partnership for Advanced Computational Infrastructure and the San Diego Supercomputer Center. Astrophysicist John Dubinski describes the science underlying the computations. Go to: http://www.npaci.edu/online/v4.9/galaxies2.html and http://www.cita.utoronto.ca/~dubinski/tflops/.
