Lunar finding doesn’t hold water
A new radar study of craters at the moon's north and south poles reveals that neither region contains substantial amounts of frozen water.

Earth sometimes shivers beneath thick blankets of ice
New analyses of old seismic data have distinguished the ground motions spawned by a previously unrecognized type of earthquake—quakes created by brief surges of massive glaciers.

Alaska shook, mountains spoke
Small pulses in atmospheric pressure detected in Fairbanks soon after the magnitude 7.9 Denali quake on Nov. 3, 2002, suggest that the temblor literally moved mountains.

Newfound fault may explain quakes
Tsunami simulations suggest that a newly discovered fault zone beneath the Atlantic Ocean could have released most of the seismic energy from three earthquakes that destroyed Lisbon, Portugal, on the morning of Nov. 1, 1755.

New technique dates glaze on desert rocks
Scientists have developed a quick, easy, portable, and nondestructive way to determine the age of desert varnish, the mysterious dark coating that slowly develops on rocks in many arid regions of the world.

Topsy Turvy: In neutrons and protons, quarks take wrong turns
Revved-up particles, namely quarks, spinning inside neutrons in the opposite direction to that of the neutrons themselves, challenge the prevailing model of how quarks behave.

Blasts from the Past: Orbiting radar spots old nuclear-test sites
A technique that analyzes satellite images to detect subtle ground motions often can perceive subsidence over underground nuclear-test sites, sometimes even if those tests occurred decades ago.
