Climate change will increase wildfire risk and lengthen fire seasons      (via sciencedaily.com)     Original source 

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.

Ancient DNA analysis reveals how the rise and fall of the Roman Empire shifted populations in the Balkans      (via sciencedaily.com)     Original source 

Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's reign.

Artificial light is luring birds to cities and sometimes to their deaths      (via sciencedaily.com)     Original source 

Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.

'Bone biographies' reveal lives of medieval England's common people -- and illuminate early benefits system      (via sciencedaily.com)     Original source 

Researchers give medieval Cambridge residents the 'Richard III treatment' to reveal hard-knock lives of those in the city during its famous university's early years. Study of over 400 remains from a hospital cemetery shows spectrum of medieval poverty, and suggests that some of Cambridge University's earliest scholars ended up in penury.

One of the largest magnetic storms in history quantified: Aurorae covered much of the night sky from the Tropics to the Polar Regions      (via sciencedaily.com)     Original source 

An international multidisciplinary team consisting of solar physicists, geophysicists, and historians from nine countries analysed observations of an extreme solar-terrestrial storm reported in historical records from February 1872. Their findings confirm that a moderate sunspot group triggered one of the largest magnetic storms ever recorded, almost covering the entire night sky with colourful aurorae in both hemispheres. If such an extreme storm occurred today, it would severely disrupt modern technological infrastructure. Their study emphasizes the importance of looking at historical records in light of modern scientific knowledge.

Dishing the dirt on human evolution: Why scientific techniques matter in archaeology      (via sciencedaily.com)     Original source 

Scientists should seek answers hidden in the dirt using proven and state-of-the-art archaeological science techniques to support new discoveries about human evolution following recent controversies at a cave site in Africa, says a group of international experts. Their recommendations follow claims published in June of this year that Homo naledi --a small-brained human species -- buried their dead in Rising Star Cave, South Africa, between 335,000 and 241,000 years ago, and may also have decorated the cave walls with engravings.

Being prepared for storm surges on the Baltic Sea coast      (via sciencedaily.com)     Original source 

The record storm surge in October 2023 caused severe damage to the German Baltic coast. Effective adaptation scenarios to rising sea levels are therefore becoming increasingly urgent. In two recent studies, researchers have modeled both the flooding extent along the Baltic Sea coastal areas and two possible upgrades for current dike lines in high resolution. They modeled various storm surge and sea level rise scenarios.

600 years of tree rings reveal climate risks in California      (via sciencedaily.com)     Original source 

The San Joaquin Valley in California has experienced vast variability in climate extremes, with droughts and floods that were more severe and lasted longer than what has been seen in the modern record, according to a new study of 600 years of tree rings from the valley.

Study of ancient British oral microbiomes reveals shift following Black Death      (via sciencedaily.com)     Original source 

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.

Solar activity likely to peak next year      (via sciencedaily.com)     Original source 

Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.

Giant sea salt aerosols play major role in Hawai'i's coastal clouds, rain      (via sciencedaily.com)     Original source 

A new study from atmospheric scientists revealed that the coastline can produce up to five times the concentration of giant sea salt aerosols compared to the open ocean and that coastal clouds may contain more of these particles than clouds over the open ocean -- affecting cloud formation and rain around the Hawaiian Islands.

Was 'witchcraft' in the Devil's Church in Koli based on acoustic resonance? The crevice cave has a unique soundscape      (via sciencedaily.com)     Original source 

The national park of Koli in eastern Finland is home to a famous, 34-metre-long crevice cave known as Pirunkirkko, or Devil's Church in English. A new study investigates the acoustics of the Devil's Church and explores whether the acoustic properties of the cave could explain the beliefs associated with it, and why it was chosen as a place for activities and rituals involving sound.

A fifth higher: Tropical cyclones substantially raise the Social Cost of Carbon      (via sciencedaily.com)     Original source 

Extreme events like tropical cyclones have immediate impacts, but also long-term implications for societies. A new study now finds: Accounting for the long-term impacts of these storms raises the global Social Cost of Carbon by more than 20 percent, compared to the estimates currently used for policy evaluations. This increase is mainly driven by the projected rise of tropical-cyclone damages to the major economies of India, USA, China, Taiwan, and Japan under global warming.
