Published Twenty-year study confirms California forests are healthier when burned -- or thinned



A 20-year experiment in the Sierra Nevada confirms that different forest management techniques -- prescribed burning, restoration thinning or a combination of both -- are effective at reducing the risk of catastrophic wildfire in California. These treatments also improve forest health, making trees more resilient to stressors like drought and bark beetles, and they do not negatively impact plant or wildlife biodiversity within individual tree stands, the research found.
Published Archaeologists unearth one of earliest known frame saddles



Recovered from looters, a new archaeological discovery from a cave in western Mongolia could change the story of the evolving relationship between humans and horses around the world.
Published Climate change will increase wildfire risk and lengthen fire seasons



Wildfires are some of the most destructive natural disasters in the country, threatening lives, destroying homes and infrastructure, and creating air pollution. In order to properly forecast and manage wildfires, managers need to understand wildfire risk and allocate resources accordingly.
Published Wildfires have erased two decades' worth of air quality gains in western United States



A new study concludes that wildfires originating in the western United States and Canada have erased air quality gains over the past two decades and caused an increase of premature deaths in fire-prone areas and downwind regions, primarily in the western U.S.
Published Strange burn: New research identifies unique patterns in Utah wildfires



Utah's variable topography produces a tremendous range of wildfire behavior, according to new research.
Published Paleolithic humans may have understood the properties of rocks for making stone tools



Research suggests that Paleolithic humans in the Middle East selected flint for their cutting tools based on differences in the mechanical properties of the rock. They seem to have purposefully selected the most suitable rocks for fashioning into tools, even being able to distinguish rocks that were unsuitable.
Published Ash can fertilize the oceans



Flames roared through Santa Barbara County in late 2017. UC Santa Barbara canceled classes, and the administration recommended donning an N95, long before the COVID pandemic made the mask a household item. Smoke and ash choked the air, but the Thomas Fire's effects weren't restricted to the land and sky. Huge amounts of ash settled into the oceans, leaving researchers to wonder what effect it might have on marine life.
Published Study of ancient British oral microbiomes reveals shift following Black Death



The Second Plague Pandemic of the mid-14th century, also known as the Black Death, killed 30-60 percent of the European population and profoundly changed the course of European history. New research suggests that this plague, potentially through resulting changes in diet and hygiene, may also be associated with a shift in the composition of the human oral microbiome toward one that contributes to chronic diseases in modern-day humans.
Published Neanderthals were the world's first artists, research reveals



Recent research has shown that engravings in a cave in La Roche-Cotard (France), which has been sealed for thousands of years, were actually made by Neanderthals. The findings reveal that the Neanderthals were the first humans with an appreciation of art.
Published First comprehensive look at effects of 2020-2021 California megafires on terrestrial wildlife habitat



In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losing critical habitat. What we don't know is how increasing fire severity at large scales is impacting their habitat and survival, because many species are not adapted to these types of 'megafires.'
Published 'Woman the hunter': Studies aim to correct history



New research combined both physiological and archaeological evidence to argue that not only did prehistoric women engage in the practice of hunting, but their female anatomy and biology would have made them intrinsically better suited for it.
Published Reforms needed to expand prescribed burns



A new paper pinpoints obstacles and suggests strategies for getting more prescribed fire on the ground in the wildfire-prone U.S. West.
Published Radiocarbon dating meets Egyptology and Biblical accounts in the city of Gezer



New dates provide detailed insights into the timing of events in the ancient city of Gezer, according to a new study.
Published Wildfire, drought cause $11.2 billion in damage to private timberland in three Pacific states, study finds



Wildfires and drought have led to $11.2 billion in damages to privately held timberland in California, Oregon and Washington over the past two decades, a new Oregon State University study found.
Published Low-intensity fires reduce wildfire risk by 60%



High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage



Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published Southern Alaska's national forests key to meeting climate, conservation goals



Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published Long-distance weaponry identified at the 31,000-year-old archaeological site of Maisières-Canal



The hunter-gatherers who settled on the banks of the Haine, a river in southern Belgium, 31,000 years ago were already using spearthrowers to hunt their game. The material found at the archaeological site of Maisières-Canal permits establishing the use of this hunting technique 10,000 years earlier than the oldest currently known preserved spearthrowers. This discovery is prompting archaeologists to reconsider the age of this important technological innovation.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests



Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published In Prehispanic Cancun, immigrants were treated just like Maya locals



Ancient people immigrated to Cancun Island and were treated just like locals, according to a new study.
