The results of two previously published reports of the events and impacts of the wildfire smoke exposure that occurred in California in 2018 are amplified from the point of view of the potential toxic mechanism involved. The wildfire led to the exposure of a breeding colony of macaque monkeys () during the peak of their breeding season in 2018-2019. Considering the timing, adverse effects, and endocrine implications reported, the cumulative evidence points to an early toxic sensitive period that can lead to birth defects in higher primates and human pregnancies. This deeper inspection of the published observations provides important caveats and useful guidance for future investigators. The unique higher primate placental-adrenal-brain axis may limit the use of many traditional toxicologic approaches. Retrospective neurological evaluations of human fetuses exposed to air pollutants during organogenesis and subsequent retrospective characterization of air samples using and animal models may be the best procedures to follow.

Grazing can reduce wildfire risk amid climate change.
Science
January 2025

Over half of Earth's land surface is covered with fire-prone vegetation, with grassy ecosystems-such as grasslands, savannas, woodlands, and shrublands-being the most extensive. In the context of the climate crisis, scientists worldwide are exploring adaptation measures to address the heightened fire risk driven by more frequent extreme climatic conditions such as droughts and heatwaves, as well as by non-native plant invasions that increased fuel loads and altered fire regimes. Although fire is intrinsic to grassy ecosystems, rising exposure to wildfire smoke harms human health and the environment.

Alzheimers Dement
December 2024
Univeristy of Washington School of Public Health, Seattle, WA, USA.
Background: Long-term exposure to ambient air pollution-including fine particulate matter <2.5µm in diameter (PM)-has previously been associated with incident dementia. As climate change drives longer and more intense wildfire seasons, exposure to PM produced by wildfires may be a unique and increasingly important risk factor for dementia.

BMC Public Health
January 2025
Heluna Health, City of Industry, City of Industry, CA, USA.
Background: Prescribed burning is an important fuel management tool to prevent severe wildfires. There is a pressing need to increase its application to reduce dry fuels in the western United States, a region that has experienced many damaging wildfires. Public support for this practice is tempered by concern around smoke impacts and escape risks.

Bottle Aging of Smoke-Affected Wines: Changes in Smoke Flavor and Chemical Composition.
J Agric Food Chem
January 2025
The Australian Wine Research Institute, P.O. Box 46, Glenside (Adelaide), SA 5065, Australia.
Winegrapes exposed to environmental wildfire smoke during ripening can be identified through analysis of volatile phenols and phenolic glycosides. While elevated concentrations of these smoke marker compounds in grapes have been shown to be predictive of composition and smoke flavor in young wines, recent research has demonstrated that not every wine produced from smoke-exposed grapes will inevitably have discernible smoke flavor when assessed as young wine 6 weeks after bottling. This is supported by anecdotal reports from wine producers that wines that do not appear noticeably smoky when young become noticeably smoky during aging.
