The number of trout in a southern Oregon stream system showed no decline one year after a fire burned almost the entire watershed, including riparian zone trees that had helped maintain optimal stream temperatures for the cold-water fish.

The Viking Age bead makers were more advanced than previously believed. A new interdisciplinary study shows that around year 700 AD, craftsmen in Ribe, Denmark, used surprisingly sophisticated and sustainable methods when giving old Roman glass mosaics new life as glass beads.

Pacific island nations suffered severe depopulation from introduced diseases as a consequence of contact with European vessels, a new study shows. The research indicates population declines were a lot larger than previously thought and shows a big reassessment of the impact of globalization in the 19th century.

Rates of traumatic injury among workers in the Oregon agricultural and construction sectors are significantly higher during periods of high heat compared with periods of more moderate weather, a recent study found.

The Plinian eruption of Mount Vesuvius around 4,000 years ago -- 2,000 years before the one that buried the Roman city of Pompeii -- left a remarkably intact glimpse into Early Bronze Age village life in the Campania region of Southern Italy. The village offers a rare glimpse into the lives of the people who lived there, and the degree of preservation led the researchers to pinpoint the timing of the eruption, based on archaeobotanical record.

With the help of geomagnetic surface surveys and subsequent hands-on digging, an excavation team has revealed new insights into the area in which the caliph's palace of Khirbat al-Minya was built on the shores of the Sea of Galilee. According to these findings, there had already been a settlement occupied by Christian or Jewish inhabitants in the immediate vicinity long before the palace was built.

The use of virtual fencing to manage cattle grazing on sagebrush rangelands has the potential to create fuel breaks needed to help fight wildfires, a recent study found.

It was the money that grew on trees. Said to be a gift from the gods, cacao for the ancient Maya was considered sacred, used not only as currency, but in special ceremonies and religious rituals. It's the progenitor plant of chocolate, and notions of luxury are embedded in its lore.

When you're cooking or cleaning inside your home, what chemicals are you breathing, and are they potentially harmful? Chemists have given us a solid start on the answer. A large, collaborative research experiment recently attempted to map the airborne chemistry of a typical home. Researchers performed typical home activities like cooking and cleaning and used sophisticated instrumentation to document the chemistry that resulted.

Researchers have identified climate-driven changes to food availability as a factor behind dramatic historical events that led the oasis city of Palmyra in Syria to its ultimate demise.

Scientists have developed a way to forecast which of the Great Basin's more than 60 million acres have the highest probability of a large rangeland fire. The forecasts come from a model developed by the researchers that combines measures of accumulated annual and perennial grass vegetation that is potential fire fuel with recent weather and climate data. When integrated, this information can be translated into maps showing the likelihood of a large wildfire -- greater than 1,000 acres--across the Great Basin. These forecasts also can be scaled down to predict fire risk for counties or even single pastures.

Archaeologists hope to settle one of modern archaeology's longstanding disputes: the date of a volcanic eruption on the Greek island of Santorini, traditionally known as Thera.

In the largest early-medieval population study to date, an interdisciplinary team consisting of geneticists and archaeologists analyzed over 400 individuals from ancient Britain, Ireland, Germany, Denmark and the Netherlands. The results show in detail one of the largest population transformations in the post-Roman world.

As the frequency of wildfires has increased, so have pollutants in the waters from burned watersheds, say researchers in a review paper that highlights the need for more research in the area.

Tiny crystals in ancient animal dung serve as key evidence in a new analysis suggesting the possibility that hunter-gatherers at Abu Hureyra, Syria, may have tended small numbers of animals just outside their dwellings between 12,800 and 12,300 years ago.

A machine learning model can evaluate the effectiveness of different management strategies.

Researchers using advanced satellite imagery have discovered an ancient reef-like landform 'hidden' in plain view on the Nullarbor Plain, which has been preserved for millions of years since it first formed when the Plain was underwater.

The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached high air layers as in the previous record wildfires in Canada during summer 2017. Research now reveals the climate impact of these huge fires: Smoke particles with a total mass of around one million tonnes spread across the southern hemisphere and affected the climate for about one and a half years by warming the upper atmosphere and cooling the lower atmosphere close to Earth's surface.

Estuaries are one of the most valuable biomes on Earth, and megafires -- like Australia's 2019/20 Black Summer fires -- represent an emerging threat to estuarine and coastal ecosystems, with the extent and proximity of the wildfire influencing the impact on estuaries.
