Scientists monitor volcanic gases with digital cameras to forecast eruptions

Scientists have shown for the first time that volcanoes emit distinctive pulses of gas a few hours before erupting, which could lead to real-time forecasting of dangerous volcanic eruptions that are difficult to predict, according to the researchers.

Collaboration between scientists and stakeholders vital to climate readiness in Alaska

Alaskan residents rely on sustenance species like salmon, caribou, and moose, but their needs can be at odds with companies mining natural resources and conservationists. The state’s future will depend on collaboration between these various stakeholders, and scientists can help bridge the gap between these groups, according to researchers at Southern Oregon University.

Elections may be a catalyst for deforestation, new research suggests

Democratic elections may be a catalyst for deforestation, according to new research. A study that examined deforestation rates during election years found that competitive elections are associated with higher rates of deforestation. The reason? Politicians are trading trees for votes, according to the researchers.

Scientists sift through lunar dirt for record of early Earth’s rocks

A team of scientists are examining crushed rocks brought back from the moon by Apollo astronauts for evidence of minerals that might have been formed in the presence of water to better understand the early formation of Earth. They presented the preliminary results of their work last month at the 2017 American Geophysical Union Fall Meeting in New Orleans.

Scientists help Costa Rican community manage dwindling water supply

As part of an interdisciplinary, international research team called FurturAgua, researchers from the University of British Columbia and Simon Fraser University have developed a tool they call the Groundwater Recharge Indicator for two watersheds in the Guanacaste Province of Costa Rica. The Groundwater Recharge Indicator can help community leaders prepare for the dry season by providing an estimate of water availability based on rainfall during the wet season. With this new tool, authorities can implement water conservation efforts such as collecting rainwater or using surface water instead of groundwater before the dry season begins and potential droughts occur, according to the researchers.

Researchers develop model that could reduce wave-induced injuries to Delaware beachgoers

Being pummeled by a large wave can quickly ruin a perfect beach day, as it may require a trip to the hospital or even worse. But researchers in Delaware have developed a new method that could predict when wave-induced injuries are most likely to occur, potentially reducing incidences of these injuries to unsuspecting beachgoers along the state’s coast, according to scientists who presented the research last month at the 2017 American Geophysical Union Fall Meeting in New Orleans.

Scientists engineer microbes to form ‘memories’ of their environment

Microbes like bacteria aren’t conscious enough to form memories, but a group of scientists in Texas developed a new way for them to do so at the genetic level. Researchers report they’ve successfully engineered microbes to report on their environments and form genetic “memories” of the event. It’s a tool that could help scientists better understand chemical cycling on Earth and how microbes share information like antibiotic resistance with one another, according to the researchers.


Promising new wildfire behavior model may aid fire managers in near real-time

Wildfires continue to scar California beyond the normal fire season in what’s been a particularly catastrophic year for natural disasters across the U.S. But a new big-data solution for predicting wildfire spread is also heating up, and it may become a useful tool in the firefighters’ arsenal, according to wildfire researchers attending the 2017 American Geophysical Union Fall Meeting.

Organic aerosols in remote areas have shorter lives than scientists assumed

Scientists find the lifetime of organic aerosols in the upper atmosphere is on the order of 10 days, far shorter than scientists previously assumed.

Lava-filled blocks on Venus may indicate geological activity

A global view of some well-known deformation features on Venus’s surface may indicate it’s capable of crustal motion, and that motion might even be happening today, scientists report.


Proteins in shark teeth could hint at what they eat

Certain molecules found in shark teeth proteins could tell scientists how the predators are connected to other animals in the food web, according to new research.


Coastal erosion threatens archaeological sites along Greenland’s fjords

Hundreds of archaeology sites lie along the shores of Greenland’s fjords and coasts, revealing the entirety of the country’s ancestral cultures from as many as four thousand years ago. Coastal erosion, however, may soon drop many of those ancestral links into the ocean.


Subterranean Serendipity: Scientists stumble upon a new way to sample magma

Scientists have never directly observed magma beneath the Earth’s surface. But thanks to the discovery of easily accessible magma chambers, it may now be possible, report scientists at the 2017 American Geophysical Union Fall Meeting in New Orleans.

Earwax like ice cores: Unlocking the past hidden in whale earplugs

Data collectors are cruising around oceans worldwide, following blooms of productivity and accumulating decades of information—all from earwax. New research shows whale earplugs provide records of the animals’ movements and diets over the course of their long lives.


The continental U.S. is experiencing more flooding, and earlier in the year

The frequency of flooding in the continental U.S. is increasing, and seasonality of floods is shifting, according to new research.
