Before they can get started at their field site - a giant cave studded with stalactites, stalagmites and human artifacts -- 15 undergraduate students must figure out how to use their virtual hands and tools. They also must learn to teleport.

A 'great' space weather super-storm large enough to cause significant disruption to our electronic and networked systems occurred on average once in every 25 years according to a new study.

New research describes a dynamic climate and vegetation model that explains when regions across Africa, areas of the Middle East, and the Mediterranean were wetter and drier and how the plant composition changed in tandem, possibly providing migration corridors throughout time.

New research provides evidence from Siberian caves suggesting that summer sea ice in the Arctic Ocean plays an essential role in stabilizing permafrost and its large store of carbon.

JAXA and NASA satellite observations show where killer electrons are generated in the Van Allen radiation belts surrounding Earth.

Researchers have investigated how the illumination of bat caves affects the animals' behavior and whether the color of light makes a difference on their flight. Although red light irritates the small mammals somewhat less than white light, from the researchers' point of view neither the entrance nor the interior of bat caves should be illuminated if bats are present.

A new study by geoscientists and climatologists provides evidence that summer monsoons from Asia and Africa may have reached into the Middle East for periods of time going back at least 125,000 years, providing suitable corridors for human migration.

Researchers investigate and describe the conservation importance of buildings relative to natural, alternative roosts for little brown bats in Yellowstone National Park.

The Neo-Assyrian Empire, centered in northern Iraq and extending from Iran to Egypt -- the largest empire of its time -- collapsed after more than two centuries of dominance at the fall of its capital, Nineveh, in 612 B.C.E. Despite a plethora of cuneiform textual documentation and archaeological excavations and field surveys, archaeologists and historians have been unable to explain the abruptness and finality of the historic empire's collapse.

Magnetic reconnection, a process in which magnetic field lines tear and come back together, releasing large amounts of kinetic energy, occurs throughout the universe. The process gives rise to auroras, solar flares and geomagnetic storms that can disrupt cell phone service and electric grids on Earth. A major challenge in the study of magnetic reconnection, however, is bridging the gap between these large-scale astrophysical scenarios and small-scale experiments that can be done in a lab.

Identifying geological features in a densely vegetated, steep, and rough terrain can be almost impossible. Imagery like LiDAR can help researchers see through the tree cover, but subtle landforms can often be missed by the human eye.

Scientists have developed a novel, standardized way of quantifying and comparing these variations in solar power. The new study may help guide the development and performance of solar photovoltaic farms -- systems that harness the sun's energy and convert it to electricity.

Scientists, studying evidence preserved in speleothems in a coastal cave, illustrate that more than three million years ago -- a time in which the Earth was two to three degrees Celsius warmer than the pre-industrial era -- sea level was as much as 16 meters higher than the present day.

A new study by physicists mimicked solar winds in the lab, confirming how they develop and providing an Earth-bound model for the future study of solar physics.

Well-known for its unique landscapes and rare wildlife, the Koytendag State Nature Reserve was yet to reveal the scale of its actual biodiversity when a series of international expeditions.

New research into waves that travel through Earth's magnetosphere deepen our understanding of the region and its interaction with our own planet, and open up new ways to study other planets across the galaxy.

Global trends in cave waters identify how stalagmites reveal past rainfall and drought patterns.

Magnetic disturbances caused by phenomena like the northern lights can be tracked by a 'social network' of ground-based instruments, according to a new study.

New research shows that the sun could experience a massive burst of energy called a superflare sometime in the next several thousand years.

The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like those that power the aurora, according to new research. In a new study, scientists found STEVE's source region in space and identified two mechanisms that cause it.
