Examining a 3-meter stack of bat feces has shed light on the landscape of the ancient continent of Sundaland. The research could help explain the biodiversity of present-day Borneo, Sumatra, and Java. It could also add to our understanding of how people moved through the region.

For the first time, a team of scholars and archaeologists has recorded and interpreted Cherokee inscriptions in Manitou Cave, Alabama. These inscriptions reveal evidence of secluded ceremonial activities at a time of crisis for the Cherokee, who were displaced from their ancestral lands and sent westward on the Trail of Tears in the 1830s.

A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt.

By studying the last 50 years of growth of a stalagmite from Mawmluh Cave, they found an unexpected connection between winter rainfall amounts in northeast India and climatic conditions in the Pacific Ocean.

Solar storms can be far more powerful than previously thought. A new study has found evidence for the third known case of a massive solar storm in historical times. The researchers believe that society might not be sufficiently prepared if a similar event were to happen now.

The Earth's magnetic shield booms like a drum when it is hit by strong impulses, according to new research.

New research shows that the sun's magnetic waves behave differently than currently believed.

The discovery of a new to science species of rare and primitive arthropod in a cave that was covered by a thick ice sheet until recently is certain to raise questions. Researchers describe a new species of cave-dwelling, insect-like dipluran from the island of Vancouver (Canada) and discuss its origin.

On Jan. 4, 2019, at 4:37 a.m. EST the CAPER-2 mission launched from Norway. The rocket flew through active aurora borealis, or northern lights, to study the waves that accelerate electrons into our atmosphere.

Biologists have discovered three new species of groundwater salamander in Central Texas, including one living west of Austin that they say is critically endangered. They also determined that an already known salamander species near Georgetown is much more endangered than previously thought. They warn that more severe droughts caused by climate change and increasing water use in Central Texas have left groundwater salamanders 'highly vulnerable to extinction.'

Scientists have developed a new technique for looking at historic solar data to distinguish trustworthy observations from those that should be used with care. This work is critical to understanding the sun's past and future as well as whether solar activity plays a role in climate change.

New research describes striking similarity of laboratory research findings with observations of the four-satellite Magnetospheric Multiscale Mission that studies magnetic reconnection in space.

Volcanoes are not fed by molten magma formed in large chambers finds a new study, overturning classic ideas about volcanic eruptions.

The fossil record of early hominins in South Africa is biased towards periods of drier climate, suggests a study of cave deposits. This finding suggests there are gaps in the fossil record, potentially obscuring evolutionary patterns and affecting our understanding of both the habitats and dietary behaviors of early hominins in this region. South Africa's highest concentration of early hominin fossils comes from the 'Cradle of Humankind' caves northwest of Johannesburg.

Scientists are studying a guppy-sized, blind, translucent fish that lives in the cave systems of northern Mexico to figure out why some animals can regenerate their hearts, while others just scar.

Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for harvesting solar and space energy will not compete for land space and can actually help each other function more efficiently.

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping.

School students have successfully identified sounds caused by a solar storm in the Earth's magnetic shield. The group of students identified a series of waves whose pitch decreased over the course of several days. They found that this event occurred after a Coronal Mass Ejection or 'solar storm' caused a great disturbance to Earth's space environment.

The magnitude and trajectory of sea-level change during the Last Interglacial, more specifically Marine Isotope Stage (MIS) 5e, is uncertain. To date the consensus view has been that sea-level may have been six to nine meters above present sea level. However, scientists are now questioning if those sea level fluctuations are accurate.

Satellites are more likely to be at risk from high-speed solar wind than a major geomagnetic storm according to a new study.
