A fifth of California's Sierra Nevada conifer forests are stranded in habitats that have grown too warm for them      (via sciencedaily.com) 

Researchers created maps showing where warmer weather has left trees in conditions that don't suit them, making them more prone to being replaced by other species. The findings could help inform long-term wildfire and ecosystem management in these 'zombie forests.'

James Webb spots super old, massive galaxies that shouldn't exist      (via sciencedaily.com) 

A team of international researchers have identified six candidate galaxies that existed roughly 500 to 700 million years after the Big Bang and are about as big as the modern Milky Way Galaxy -- a feat that scientists didn't think was possible.

Researchers discover mysterious source of 'heartbeat-like' radio bursts in a solar fare      (via sciencedaily.com) 

A solar radio burst with a signal pattern, akin to that of a heartbeat, has been pinpointed in the Sun's atmosphere, according to a new study. An international team of researchers has reported uncovering the source location of a radio signal coming from within a C-class solar flare more than 5,000 kilometers above the Sun's surface.

Improving the performance of satellites in low Earth orbit      (via sciencedaily.com) 

On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.

Physicists create new model of ringing black holes      (via sciencedaily.com)     Original source 

A new analysis has modeled black hole collisions in more detail and revealed so-called nonlinear effects within gravitational waves. Nonlinear effects happen 'when waves on the beach crest and crash.'

Newly discovered form of salty ice could exist on surface of extraterrestrial moons      (via sciencedaily.com)     Original source 

An international team has found two new crystal structures for salty ice, or solid hydrate made from water and sodium chloride. The newly discovered material's properties match those of the substance seen on the surface of icy moons, like Europa and Ganymede, and may offer clues to their icy oceans.

Space travel influences the way the brain works      (via sciencedaily.com)     Original source 

Scientists have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting -- even after 8 months back on Earth.

Astrophysics: Scientists observe high-speed star formation      (via sciencedaily.com)     Original source 

New observations have brought to light that stars can form through the dynamic interaction of gas within interstellar gas clouds. This process unfolds faster than previously assumed, research within the FEEDBACK programme on board the flying observatory SOFIA revealed.

Tadpole playing around black hole      (via sciencedaily.com)     Original source 

A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help determine what is responsible for the shape and motion of the Tadpole.

Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?      (via sciencedaily.com)     Original source 

If you want to build a habitable planet, ice is a key ingredient. The ice can be found in enormous clouds in the Universe and it is the main carrier of the necessary elements such as carbon, hydrogen, oxygen, nitrogen and sulphur. These elements are part of the atmosphere around planets and part of molecules like sugar, alcohols and simple amino acids as well. The new James Webb Space Telescope (JWST) has contributed to the discovery of different ices in a molecular cloud, 'Chameleon 1' -- one of the coldest and darkest regions to have ever been explored. Astronomers assume that these types of molecules were also present in the cold cloud of gas and dust forming our own solar system.

New technique maps large-scale impacts of fire-induced permafrost thaw in Alaska      (via sciencedaily.com) 

Researchers have developed a machine learning-based ensemble approach to quantify fire-induced thaw settlement across the entire Tanana Flats in Alaska, which encompasses more than 3 million acres. They linked airborne repeat lidar data to time-series Landsat products (satellite images) to delineate thaw settlement patterns across six large fires that have occurred since 2000. The six fires resulted in a loss of nearly 99,000 acres of evergreen forest from 2000 to 2014 among nearly 155,000 acres of fire-influenced forests with varying degrees of burn severity. This novel approach helped to explain about 65 percent of the variance in lidar-detected elevation change.

Western wildfires destroying more homes per square mile burned      (via sciencedaily.com) 

Between 2010 and 2020, human ignitions started 76% of the Western wildfires that destroyed structures, and those fires tended to be in flammable areas where buildings are increasingly common. Three times as many homes and other structures burned in these ten years than in the previous decade.

Understanding plants can boost wildland-fire modeling in uncertain future      (via sciencedaily.com) 

A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.

How to apply lessons from Colorado's costliest wildfire to drinking water systems      (via sciencedaily.com) 

While communities and governments nationwide have been facing the impact of wildfires on drinking water systems, no national synthesis of scientific and policy needs has been conducted. Now, a study has outlined the scientific and policy needs specific to drinking water systems' resilience to wildfires.

Unprecedented levels of high-severity fire burn in Sierra Nevada      (via sciencedaily.com) 

High-severity wildfire in California's Sierra Nevada forests has nearly quintupled compared to before Euro-American settlement, rising from less than 10% per year then to up to 43% today, a new study finds.

What's driving re-burns across California and the West?      (via sciencedaily.com) 

Seasonal temperature, moisture loss from plants and wind speed are what primarily drive fires that sweep across the same landscape multiple times, a new study reveals. These findings and others could help land managers plan more effective treatments in areas susceptible to fire, particularly in the fire-ravaged wildland-urban interfaces of California.

20,000 premature US deaths caused by human-ignited fires each year      (via sciencedaily.com) 

A new study shows that smoke particles from human-lit fires are responsible for over 80% of smoke-related deaths each year. The study shows that smoke pollution is on the rise, reducing air quality, and leading to increased illness and premature deaths.
