A research team examined what happens to mountain snowpacks when sunny, midwinter dry spells occur in forests impacted by severe wildfire.

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.

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.

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers discovered Medakamo hakoo, whose DNA sequence didn't match any on record. This new species is the smallest known freshwater green algae, with inherent qualities which enable it to be cultured stably at high density, meaning it could be effectively used to produce useful products for food and industry.

Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

Researchers uncover for the first time the mechanism that likely explains how embryos form either a larva or a miniature version of the adult.

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.

The transport of molecules along the cell's skeleton plays a role in cancer metastasis, researchers show.

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study. The work solves a mystery that has long puzzled biologists.

Under cold conditions, not only the mother plant but also the father plant can pass on its chloroplasts to the offspring.

Scientists succeed in boosting the efficiency of CRISPR/Cas9 and related methods and modifying initially inaccessible DNA sequences. They fine-tuned these tools to enable effective genetic screening for modelling specific gene mutations.

Immunogeneticists have discovered a new genetic disorder that causes immunodeficiency and profound susceptibility to opportunistic infections including a life-threatening fungal pneumonia.

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.

The red junglefowl -- the wild ancestor of the chicken -- is losing its genetic diversity by interbreeding with domesticated birds, according to a new study.

     (via sciencedaily.com) 

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

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.

Old Yellow Enzymes (OYEs) were discovered in the 1930s and have been the subject of much research ever since. This is because these biocatalysts -- coloured yellow by an auxiliary molecule -- are capable of performing reactions that are very valuable for the chemical industry, such as producing drug precursors or fragrances. Even though OYEs are found in many organisms, their natural role for these organisms has hardly been understood so far -- possibly because the research focus has been on their biotechnological application. Researchers have now shown that an OYE of the unicellular green alga Chlamydomonas reinhardtii is vital for this plant microorganism to protect itself from photooxidative stress.
