The Chao volcano in northern Chile with a lava coulée approx. 14.5 km long (centre of picture). The composition of the lava matches that of deposits of adjacent supervolcanic calderas. Chao erupted about 75,000 years ago, but zircon crystals...
A University of Wyoming researcher contributed to a paper that demonstrated, for the first time, direct observation of cloud seeding -- from the growth of the ice crystals through the processes that occur in the clouds to the eventual...
Nuisance flooding has increased on U.S. coasts in recent decades due to sea level rise, and new research co-authored by the University of Central Florida uncovered an additional reason for its added frequency. In a study appearing today in the...

In Europe's temperate forests, less common plant species are being replaced by more widespread species. An international team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv) and the Martin Luther University Halle-Wittenberg (MLU) has found...

Something peculiar is happening in the azure waters off the rocky cliffs of Ischia, Italy. There, streams of gas-filled volcanic bubbles rising up to the surface are radically changing life around them by making seawater acidic. Stanford researchers studying...
The first reports of seismic activity and ground vibrations on Mars are in. The red planet has a moderate level of seismic activity, intermediate between Earth and the Moon. An international team that includes University of Maryland geologists released preliminary...
Summary of the locations where gas hydrate occurs beneath the seafloor, in permafrost areas, and beneath some ice sheets, along with the processes (shown in red) that destroy methane (sinks) in the sediments, ocean, and atmosphere. The differently colored...
