Researchers found thousands of seedlings growing after recent fires in Montana, especially at sites with cooler, damper conditions -- often found in the shade of the dead trees and upper canopy, as well as on the north side of mountains with higher elevations and more undergrowth. Researchers found fewer seedlings at sites with less shade and drier, hotter conditions.

A new study shows for the first time that wildfires burning in West Coast states can strengthen storms in downwind states. Heat and tiny airborne particles produced by western wildfires distantly intensify severe storms, in some cases bringing baseball-sized hail, heavier rain and flash flooding to states like Colorado, Wyoming, Nebraska, Kansas, Oklahoma, and the Dakotas.

Los Angeles is known for its movie stars and beaches. It's also known for being one of only two megacities in the world that supports a population of big cats. Despite being surrounded by a vast network of busy freeways and over ten million people, mountain lions have somehow managed to eke out a living in the wooded LA-area hills. Now, researchers have found that wildfires, and specifically the 2018 Woolsey fire, are putting the LA mountain lions' future in more doubt.

The strong winds and torrential rains that accompany a cyclone do tremendous damage to ecosystems, and this damage can make them more prone to future wildfires. As intense cyclones are projected to become more frequent worldwide, a team of researchers examines the links between cyclones and forest fires, how they fuel one another, and why we may see fires burning in unlikely places in the future.

The metal-carbon dioxide battery is a promising and environmentally friendly technology, but its energy efficiency is limited. Recently, a research team has discovered an innovative way to overcome this problem by introducing an unconventional phase nanomaterial as a catalyst, boosting battery energy efficiency up to 83.8%. The study reveals a novel design of catalysts for the new generation of meta-gas batteries that can contribute to carbon neutral goals.

When you're cooking or cleaning inside your home, what chemicals are you breathing, and are they potentially harmful? Chemists have given us a solid start on the answer. A large, collaborative research experiment recently attempted to map the airborne chemistry of a typical home. Researchers performed typical home activities like cooking and cleaning and used sophisticated instrumentation to document the chemistry that resulted.

Researchers offer a new mixture of metallic elements to serve as lithium-ion cathodes. This 'high-entropy doping strategy' is part of an effort to remove cobalt -- and expensive and geopolitically problematic mineral -- from LI batteries.

Scientists have developed a way to forecast which of the Great Basin's more than 60 million acres have the highest probability of a large rangeland fire. The forecasts come from a model developed by the researchers that combines measures of accumulated annual and perennial grass vegetation that is potential fire fuel with recent weather and climate data. When integrated, this information can be translated into maps showing the likelihood of a large wildfire -- greater than 1,000 acres--across the Great Basin. These forecasts also can be scaled down to predict fire risk for counties or even single pastures.

As the frequency of wildfires has increased, so have pollutants in the waters from burned watersheds, say researchers in a review paper that highlights the need for more research in the area.
