Future high temperature extremes and soil moisture conditions may cause some regions to become more suitable for rainfed, or non-irrigated, agriculture, while causing other areas to lose suitable farmland, according to a new U.S. Geological Survey study.  These future conditions will cause an overall increase in the area suitable to support rainfed agriculture within dryland…

For scientists trying to understand what ancient Mars might have been like, the red planet sends some mixed signals. Water-carved valleys and lakebeds leave little doubt that water once flowed on the surface. But climate models for early Mars suggest average temperatures around the globe stayed well below freezing.

How can a bee fly straight home in the middle of the night after a complicated route through thick vegetation in search of food? For the first time, researchers have been able to show what happens in the brain of the bee.

On May 29, 2006, mud started erupting from several sites on the Indonesian island of Java. Boiling mud, water, rocks and gas poured from newly-created vents in the ground, burying entire towns and compelling many Indonesians to flee. By September 2006, the largest eruption site reached a peak, and enough mud gushed on the surface…

An estimated 5.5 million Americans live with Alzheimer’s disease, a type of dementia that causes problems with memory, thinking and behavior. Although treatments can slow the worsening of symptoms, scientists are still working to better understand the neurodegenerative disease so that curative and preventative medicines can be developed. A new imaging system could help speed…

Every year, millions of tonnes of plastic debris ends up in the sea – a global environmental problem with unforeseeable ecological consequences. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on…

Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.Late last month, a stratovolcano in Bali named Mount Agung began to smoke. Little earthquakes trembled beneath the mountain. Officials have since evacuated thousands of people to prevent what…

The strong El Niño event of 2015-2016 provided NASA and NOAA an unprecedented opportunity to test the effectiveness of the newest observation tool to measure global atmospheric carbon dioxide concentrations — NASA’s Orbiting Carbon Observatory-2 satellite or OCO-2.Observations of carbon dioxide concentrations over the tropical Pacific from the satellite were validated by data from NOAA’s…

Researchers at the Department of Energy's Pacific Northwest National Laboratory have created a continuous thermo-chemical process that produces useful biocrude from algae. The process takes just minutes and PNNL is working with a company which has licensed the technology to build a pilot plant using the technology.

As devastating wildfires continue to rage in the western U.S. and Canada, a team of environmental engineers at Washington University in St. Louis have discovered that light-absorbing organic particulate matter, also known as brown carbon aerosol, in wildfire smoke loses its ability to absorb sunlight the longer it remains in the atmosphere.
