By being coupled with a layer of mobile electrical charges on the Earth's surface, radio waves could travel over the ground to areas that would normally be unreachable, like behind a mountain.Read More »Geology & Geophysics
Tide gauges can help measure sea level change, but their limited locations and short records make it hard to pinpoint trends. Now researchers are evaluating the instruments' limitations.Read More »
Tracking isotope patterns in tap water also reveals metropolitan water management choices, population ranges, episodes of environmental stress, and even information on household income.Read More »Geology & Geophysics
New research suggests that continually monitoring gravity changes near active volcanoes could provide insights into volcanic activity.Read More »Geology & Geophysics
Many seismic wave models are based on an erroneous assumption about the Earth's interior. A new technique corrects this by eliminating false signals produced by models.Read More »Space Science & Space Physics
Using data from the European Space Agency's Swarm mission, scientists find that abrupt drops in the ionosphere's electron density may cause low-orbiting satellites to lose contact with GPS satellitesRead More »Atmospheric Sciences
A study suggests that known combustion and photochemical sources of nitrous acid, a precursor to ground-level ozone, are enough to explain levels seen in the atmosphere.Read More »
