As the National Park Service celebrates its 100th anniversary, we celebrate ongoing Earth and atmospheric research made possible by conservation efforts.
Sweet spots of volcanic heat that are not too close to active eruptions may hold the world's richest reservoirs of the scientifically and medically important gas helium.
When the gravity of the Sun and Moon causes Earth's crust to bulge every 2 weeks, slow-moving earthquakes proliferate in the lower reaches of the San Andreas, a new study finds.
Landing robotics distinguish the craft from past models, allowing researchers to target smaller flat areas that are surrounded by rock.
New evidence indicates ancient warming spells that coincided with prodigious volcanism and a powerful meteorite impact, both seen as possible causes of mass extinctions about 66 million years ago.
The length of quiet periods predicts the severity of eruption events, according to a new model that might soon help forecast explosions worldwide.
Rogue waves form without warning and can tower more than 25 meters high. A new mathematical approach shows promise at simulating how high these waves can be.
A study of nanoscale, iron- and sulfur-rich impurities in diamonds provides new clues to the chemical processes that produce the superhard crystals and at what depths they occur.
East Coast species will face the most difficulty finding routes to cooler homes as climate change forces migration.
Tropical fires and drought-stricken ecosystems that normally serve as sinks will release carbon, contributing to high atmospheric concentrations through 2016 and beyond.
