In disaster mitigation planning for future large earthquakes, seismic ground motion predictions are a crucial part of early warning systems. The way the ground moves depends on how the soil layers amplify the seismic waves (described in a mathematical site 'amplification factor'). However, geophysical explorations to understand soil conditions are...

Researchers have discovered a novel way to combine curcumin -- the substance in turmeric -- and gold nanoparticles to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.

Legalization of recreational marijuana reduces demand for costly prescription drugs through state Medicaid programs, according to a new analysis.

Follow the pollen. Records from past plant life tell the real story of global temperatures. Warmer temperatures brought plants -- and then came even warmer temperatures, according to new model simulations.

A new article presents step-by-step protocols for creating publishable 2D and 3D visualizations. The techniques will allow anyone to produce high-quality images and models with minimal effort and cost.

New research combines demographic data with the distribution of GI and geographic areas prone to rainwater flooding in Portland, Phoenix and Atlanta and asks whether these cities are equitably building GI to mitigate flood risks.

Scientists explore microbial communities flourishing in leachate, a liquid percolating through solid waste in a landfill. They find that the composition and behavior of specific microbes found in arid landfills, like those in Arizona, are distinct from similar communities in more subtropical or temperate climates. Microbial composition also differs depending...

This South American wildflower was presumed extinct -- to the point that its official scientific name is Gasteranthus extinctus. But now, scientists are reporting the first confirmed sightings in 40 years. This not only means that this one little flower made it, but that an important concept in conservation biology...

Gut microbiota by-products circulate in the bloodstream, regulating host physiological processes including immunity, metabolism and brain functions. Scientists have discovered that hypothalamic neurons in an animal model directly detect variations in bacterial activity and adapt appetite and body temperature accordingly. These findings demonstrate that a direct dialog occurs between the...

Following years of attention to surplus nitrogen in the environment, our evolving understanding has led to new concerns about nitrogen insufficiency in areas of the world that do not receive significant inputs of nitrogen from human activities. A multi-institutional team of researchers now describes the causes of declining nitrogen availability...
