How natural hydrogen, hiding deep in the Earth, could serve as a new energy source

In the search for more, new and cleaner sources of energy, a largely untapped resource is emerging: natural hydrogen.

Unlike hydrogen produced from industrial processes, natural hydrogen forms through geological reactions that occur normally within the Earth’s crust, meaning it costs nothing to make – though it costs some amount ...Read more

The Mojave Desert is a hot spot for off-roading. Here's why a judge shut down more than 2,200 miles of trails

MOJAVE DESERT — The desert tortoise, a once-resilient reptile, is a keystone species in the Mojave Desert, where other animals depend for their survival on the burrows it digs.

But it is imperiled in California thanks in part to an unusual predator: off-road vehicles that race through thousands of miles of trails — official and unofficial �...Read more

Climate models are systems of differential equations based on the basic laws of physics, fluid motion and chemistry. They divide the planet into a 3D grid, apply the equations and evaluate the results. Within these models, the atmosphere component, for example, calculates winds, heat transfer, radiation, relative humidity and surface hydrology.

The cost of casting animals as heroes and villains in conservation science

Scientists are philosophers, explorers, data collectors and number crunchers. They are also storytellers, placing data within a broader scientific and societal context. How they tell these stories matters.

In our work as ecologists, we find that the “hero-villain” narrative trope is a popular tool in ecology and conservation ...Read more
