Research team creates statistical model to predict COVID-19 resistance      (via sciencedaily.com) 

Researchers have created and preliminarily tested what they believe may be one of the first models for predicting who has the highest probability of being resistant to COVID-19 in spite of exposure to SARS-CoV-2, the virus that causes it.

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.'

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.

AI technologies have even more exaggerated biases in perception of facial age than humans      (via sciencedaily.com) 

Researchers tested a large sample of the major AI technologies available today and found that not only did they reproduce human biases in facial age recognition, but they exaggerated those biases.

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.

Novel method for assigning workplaces in synthetic populations unveiled      (via sciencedaily.com) 

Synthetic populations are computer-generated models that mimic real-world populations in terms of characteristics such as age, gender, and occupation; they are useful when conducting social simulations. In a recent study, researchers developed a new approach to assign workplaces to individuals in a synthetic Japanese population with household information, based on ODI (Origin-Destination-Industry) data. Their efforts will enable more accurate, realistic simulations of the day-time distribution of workers in Japan, helping to improve decision-making and planning.

In the wake of a wildfire, embers of change in cognition and brain function linger      (via sciencedaily.com) 

Five years after the deadliest and most destructive wildfire in California history, researchers document persistent differences in cognitive function among survivors.

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.

Bird diversity increased in severely burned forests of Southern Appalachian mountains      (via sciencedaily.com) 

A new study found bird diversity increased in North Carolina mountain forest areas severely burned by wildfire in 2016, reinforcing that while wildfire can pose risks to safety and property, it can be beneficial to wildlife. The study results could help forest managers better predict bird responses to wildfire, and manage forests to benefit birds.

Climate whiplash increased wildfires on California's west coast about 8,000 years ago      (via sciencedaily.com) 

Researchers have been studying the effects of the sudden decrease in global temperatures that occurred about 8,200 years ago, the so-called 8.2-kiloyear event, with the help of mineral deposits present in White Moon Cave in Northern California. New indications show that oscillations between extreme wetness and aridity in California were closely linked with the occurrence of wildfires. The researchers have concluded that such events are likely to become more common in the face of human-induced climate change.

Americans flocking to fire: National migration study      (via sciencedaily.com) 

Americans are leaving many of the U.S. counties hit hardest by hurricanes and heatwaves -- and moving towards dangerous wildfires and warmer temperatures, says one of the largest studies of U.S. migration and natural disasters. These results are concerning, as wildfire and rising temperatures are projected to worsen with climate change. The study was inspired by the increasing number of headlines of record-breaking natural disasters.
