Frequency-dependent squeezing pushes LIGO sensitivity to new records Researchers at the gravitational-wave observatory were already using nonclassical states of light to boost their measurement precision. Now they've unveiled an even more subtle trick. Johanna L. Miller Wildfire heat may be recorded in grains of sand Quartz sand from the forest floor gets more reactive to light after being heated. The behavior could help geoscientists unearth evidence of past fires.

Physics offers biology tools and techniques to attack the disease, but both sciences must work together on the basic problems of growth. Arthur K. Solomon An electronic fingertip with a sense of touch The new sensor resolves ultrafine surface features typical of the dimensions of fabric textures. R.

Proponents of Project Plowshare argued that using nuclear explosives for peaceful means offered technical and economic advantages. But getting the biggest bang for the buck didn't outweigh the varied environmental and sociopolitical costs of their use.
