Satellite tracking shows how ships affect clouds and climate
By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected.

Radio noise maps show where emergency communications could get tricky
Rather than riding in trucks to maneuver around the streets of Boston, the team got in their steps. They carried radiofrequency monitoring equipment in backpacks sporting a towering radio antenna, a recording device and an aluminum “radio-proof box” containing a laptop – a key feature to prevent the computer from contaminating their data. In total, the contraption weighed 15.4 kilograms (34 pounds).

Extreme solar storms may be more frequent than previously thought
New research in AGU’s journal Space Weather indicates storms like the 1859 Carrington Event are not as rare as scientists thought and could happen every few decades, seriously damaging modern communication and navigation systems around the globe.

Shape of volcanic ash influences contamination of water sources in volcanically active regions
Contaminants from volcanic eruptions leach into water at different rates depending on the shape of the volcanic ash particles, according to new research that could enhancing scientists’ ability to predict water quality risk in volcanically active regions.

Water distribution affects exoplanets’ habitable zone
A new study finds land planets, which have equal to or less than 10 percent of the volume of Earth’s water, can remain habitable at a closer distance to their host star if most of their water is at the planet’s poles. This means the habitable zone for these types of planets may be different than previously assumed.

Historic earthquakes suggest Trans-Mexican Volcanic Belt’s quiet regions are active
Seemingly low-hazard seismic regions in Mexico have experienced multiple, strong earthquakes since the 1500s, new research finds, suggesting the regions have many unmapped, active fault lines. The areas are inside the Trans-Mexican Volcanic Belt, home to roughly 40 percent of Mexico’s population, who may be unaware of the land’s seismic history.

Ice islands on Mars and Pluto could reveal past climate change
Many of the craters of Mars and Pluto feature relatively small ice islands unattached to their polar ice caps. These ice islands could be records of past climate change on Mars and Pluto, and could also provide clues about the workings of Martian water and ice, according to a new study in AGU’s Journal of Geophysical Research: Planets.
New study complicates theory that ancient impact pierced Moon’s crust
A new study finds the crater’s crust mainly consists of a common lunar crustal mineral not detected in earlier analyses. The new results suggest the basin floor may not have exposed lunar mantle material as previously reported. “We are not seeing the mantle materials at the (Chang’E 4) landing site as expected,” said Hao Zhang, a planetary scientist at the China University of Geosciences, Wuhan, China, and a co-author of the new study.

Study Tallies Huge Hidden Health Costs from Climate Change
Research sheds light on public health impact from climate-related events, spotlight on CO, FL, MI, NV, NJ, NY, NC, OH, TX, WA, and WI.
New study suggests gigantic masses in Earth’s mantle untouched for more than 4 billion years
Ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below the Earth’s crust, offering a window into the building blocks of our planet, according to new research.
