Published New gels could protect buildings during wildfires



Researchers have developed a sprayable gel that creates a shield to protect buildings from wildfire damage. It lasts longer and is more effective than existing commercial options.
Published To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say



Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.
Published Fossil hotspots in Africa obscure a more complete picture of human evolution



A new study shows how the mismatch between where fossils are preserved and where humans likely lived may influence our understanding of early human evolution.
Published Action plan to help patients with lung disease cope with wildfire smoke



A multidisciplinary team has developed an action plan to help patients with respiratory diseases mitigate the consequences of poor air quality from wildfires.
Published Less severe forest fires can reduce intensity of future blazes



Low- and moderate-severity forest wildfires can reduce the intensity of future fires, according to new research on 'reburns.'
Published Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia



Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.
Published Rare archaeological site reveals 'surprising' Neanderthal behaviour at Pyrenees foothills



An unchartered area in the foothills of the Southern Pyrenees in Spain is providing insights into a poorly known period of Neanderthal history, offering clues that could help archaeologists uncover the mystery of their downfall, according to new research.
Published Decoding the world's largest animal genome



Scientists have sequenced the largest genome of all animals, the lungfish genome. Their data help to explain how the fish-ancestors of today's land vertebrates were able to conquer land.
Published Climate change raised the odds of unprecedented wildfires in 2023-24



Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published New interpretation of runic inscription reveals pricing in Viking age



A new interpretation of the runic inscription on the Forsa Ring (Forsaringen in Swedish), provides fresh insights into the Viking Age monetary system and represents the oldest documented value record in Scandinavia. The inscription describes how the Vikings handled fines in a flexible and practical manner.
Published House call: A new study rethinks early Christian landmark



Since its discovery by modern researchers a century ago, an ancient structure known as the 'Christian building' has become widely considered the cornerstone of early Christian architecture. Constructed around 232 C.E. in the ancient city of Dura-Europos, a Roman garrison town in what is now eastern Syria, the building is the only example of a 'house church,' or domus ecclesiae, a domestic space that was renovated for worship by Christians at a time when the open practice of their faith is thought to have made them subject to persecution.
Published Canadian wildfires are affecting US air quality and raising health concerns



Climate-driven wildfire events are rapidly transferring harmful particulate matter containing toxic chemicals over long distances, compromising air quality in the New Jersey and New York City areas, according to recent research.
Published New York City's fireworks display prompts temporary surge of air pollution



In 2023, roughly 60,000 firework shells exploded above Manhattan's East River as part of Macy's Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian wildfire had blanketed the area a month before, according to the results of a new study.
Published Carvings at ancient monument may be world's oldest calendars



Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.
Published Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis



A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.
Published Half a billion-year-old spiny slug reveals the origins of mollusks



Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
Published Demographics of north African human populations unravelled using genomic data and artificial intelligence



A new study places the origin of the Imazighen in the Epipaleolithic, more than twenty thousand years ago. The research concludes that the genetic origin of the current Arab population of north Africa is far more recent than previously believed, placing it in the seventh century AD. The team has designed an innovative demographic model that uses artificial intelligence to analyze the complete genomes of the two populations.
Published Modern behavior explains prehistoric economies



What if the 'Market Economy' always existed? Archaeologists tried to answer this question by researching how much Bronze Age people used to spend to sustain their daily lives. Their results show that, starting at least 3,500 years ago, the spending habits of prehistoric Europeans were not substantially different from what they are today.
Published California a botanical and climate change hot spot



Climate-driven shifts in California's biodiversity call for innovation and continued environmental stewardfship, says a new study. California's 30x30 Initiative and efforts to harmonize biodiversity with renewable energy are promising steps, while wildfire strategies need to further adapt.
Published The ancestor of all modern birds probably had iridescent feathers



Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
