The 2021 Dixie Fire burned over nearly 1 million acres in California and cost $637 million to suppress, making it the largest and most expensive wildfire to contain in state history. Fire history largely determined how severely the wildfire burned, and low-severity fire treatments had the largest impact on reducing the worst effects of the fire, according to a research team.

A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area.

New research highlights how the risk of wildfire is rising globally due to climate change -- but also, how human actions and policies can play a critical role in regulating regional impacts. The study shows that anthropogenic climate change is a 'push' factor that enhances the risk of wildfires globally.

New research reveals that wildfires may have been a key contributor to the total collapse of land ecosystems during Earth's worst mass extinction event over 250 million years ago.

A research team realized magnetic reconnection driven by electron dynamics in laser-produced plasmas and measured the pure electron outflows. Their findings will be applied not only to space and astrophysical plasmas, but also to magnetic propulsion and fusion plasmas.

Intense heat in the southwestern United States broke records last summer partly because it hit in tandem with an unusually severe drought, finds a new study measuring for the first time how the two extreme weather events dangerously interacted in real time.

A new study examines the context surrounding the fires and offers insight into the historical role of large, high-severity fires -- and the future of wildfires -- west of the Cascades.

Increasing frequency and size of wildfires in the United States over the past several decades affect everything from human life and health to air quality, biodiversity, and land use. The US dairy industry is not exempt from these effects. The Western states, where wildfires are especially prevalent, are home to more than two million dairy cows that produce more than 25% of the nation's milk. A new report examines how dairy cattle in the Western United States may be affected by unique air pollutants from wildfire smoke.

While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires have been a long-standing part of Earth's systems without the influence of humans for hundreds of millions of years.

Temperatures inside new wildfire shelter prototypes remained within survival limits for longer, and the shelters took longer to break open, compared with an industry standard.

Scientists have refined the use of magnetic fields to improve the performance of doughnut-shaped fusion facilities known as tokamaks. The improved technique protects internal parts from damage by instabilities and allows tokamaks to operate for longer without pausing.

A chemistry team has engineered a cobalt complex to act as a noninvasive chemical thermometer. They've done so by making the cobalt complex's nuclear spin ­-- a workhorse, fundamental magnetic property ­­-- mimic the agile, but less stable sensitivity of an electron's spin.

Over nearly nine years, the Daya Bay Reactor Neutrino Experiment captured an unprecedented five and a half million interactions from subatomic particles called neutrinos. Now, the international team of physicists has reported the first result from the experiment's full dataset -- the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their 'flavor.' The result will help physicists explore some of the biggest mysteries surrounding the nature of matter and the universe.

Researchers have helped peer inside a nova -- a type of astrophysical nuclear explosion -- without leaving Earth. These stellar events help forge the universe's chemical elements, and astronomers have explored their nature with an intense isotope beam and a custom experimental device with record-setting sensitivity.

After running simulations on the world's most powerful supercomputer, an international team of researchers has developed a theory for the nuclear structure and origin of carbon-12, the stuff of life. The theory favors the production of carbon-12 in the cosmos.

Scientists used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for decades.

Scientists have used a mathematical technique to design powerful magnets with straighter shapes for stellarator fusion facilities, allowing for easier manufacturing and maintenance.

While most missions to the moon and other planets rely upon solar power, scientists have assumed that any extended surface mission involving humans would require a more reliable source of energy: nuclear power. Improvements in photovoltaics are upending this calculus. A new study concludes that a solar power system would weigh less than a nuclear system, and would be sufficient to power a colony at sites over nearly half the surface.

Technetium-99m is the world's most commonly used medical radioisotope, but regularly suffers from supply chain shortages, threatening the ability of doctors to diagnose a raft of ailments. But an alternative production technique looks set to make the radioisotope much more easily produced.
