Published Waxing and waning of environment influences hominin dispersals across ancient Iran


A world-first model of paleoclimate and hydrology in Iran has highlighted favourable routes for Neanderthals and modern human expansions eastwards into Asia. The findings reveal that multiple humid periods in ancient Iran led to the expansions of human populations, opening dispersal route across the region, and the possible interactions of species such as Neanderthals and our own Homo sapiens.
Published Oldest human genome from southern Spain


A new study reports on genomic data from a 23,000-year-old individual who lived in what was probably the warmest place of Europe at the peak of the last Ice Age. The oldest human genome recovered from the southern tip of Spain adds an important piece of the puzzle to the genetic history of Europe.
Published Steel was being used in Europe 2900 years ago


Researchers have discovered what they believe is the earliest use of steel in Europe -- on Iberian stone pillars from the Final Bronze Age.
Published Mysterious new behavior seen in whales may be recorded in ancient manuscripts


In 2011, scientists recorded a previously unknown feeding strategy in whales around the world. Now, researchers in Australia think they may have found evidence of this behaviour being described in ancient accounts of sea creatures, recorded more than 2,000 years ago. They believe that misunderstandings of these descriptions contributed to myths about medieval sea monsters. Whales are known lunge at their prey when feeding, but recently whales have been spotted at the surface of the water with their jaws open at right angles, waiting for shoals of fish to swim into their mouths. A clip of this strategy was captured in 2021 and went viral on Instagram. This strategy seems to work for the whales because the fish think they have found a place to shelter from predators, not realising they are swimming into danger. It's not known why this strategy has only recently been identified, but scientists speculate that it's a result of changing environmental conditions -- or that whales are being more closely monitored than ever before by drones and other modern technologies.
Published Deadly waves: Researchers document evolution of plague over hundreds of years in medieval Denmark


Scientists who study the origins and evolution of the plague have examined hundreds of ancient human teeth from Denmark, seeking to address longstanding questions about its arrival, persistence and spread within Scandinavia.
Published Archaeologists uncover early evidence of brain surgery in Ancient Near East


A recent excavation in Megiddo, Israel, unearthed the earliest example of a particular type of cranial surgery in the Ancient Near East -- and potentially one of the oldest examples of leprosy in the world.
Published Hidden from the Romans: 200 tons of silver on the shores of the river Lahn


In their search for silver ore, the Romans established two military camps in the Bad Ems area near Koblenz in the 1st century AD.
Published Chromo-encryption method encodes secrets with color


In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published Caribou have been using same Arctic calving grounds for 3,000 years


Caribou have been using the same Arctic calving grounds for more than 3,000 years. Female caribou shed their antlers within days of giving birth, leaving behind a record of their annual travels across Alaska and Canada's Yukon that persists on the cold tundra for hundreds or even thousands of years. Researchers recovered antlers that have sat undisturbed on the arctic tundra since the Bronze Age.
Published New research suggests drought accelerated empire collapse



The collapse of the Hittite Empire in the Late Bronze Age has been blamed on various factors, from war with other territories to internal strife. Now, scientists have used tree ring and isotope records to pinpoint a more likely culprit: three straight years of severe drought.
Published Video game playing causes no harm to young children's cognitive abilities, study finds


Despite old fears that bad effects follow excessive video game playing or questionable game choices, researchers found those factors mattered little, if any, in children's brain health. The bad news? Video games assumed to be effective learning tools showed no meaningful effects, either.
Published Changing climate conditions likely facilitated early human migration to the Americas at key intervals, research suggests



Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper shows.
Published Prehistoric human migration in Southeast Asia driven by sea-level rise


An interdisciplinary team of scientistshas found that rapid sea-level rise drove early settlers in Southeast Asia to migrate during the prehistoric period, increasing the genetic diversity of the region today.
Published Remapping the superhighways travelled by the first Australians reveals a 10,000-year journey through the continent


New research has revealed that the process of 'peopling' the entire continent of Sahul -- the combined mega continent that joined Australia with New Guinea when sea levels were much lower than today -- took 10,000 years. Sophisticated models show the scale of the challenges faced by the ancestors of Indigenous people making their mass migration across the supercontinent more than 60,000 years ago. This pattern led to a rapid expansion both southward toward the Great Australian Bight, and northward from the Kimberley region to settle all parts of New Guinea and, later, the southwest and southeast of Australia.
Published Vikings crossing the North Sea to Britain brought their horses, dogs and other animals


An analysis of cremated bone fragments from burial mounds in Derbyshire, UK, provides the first solid evidence that Vikings crossed the North Sea with horses, dogs and other animals as early as the ninth century AD. Researchers analyzed samples of human and animal remains, finding that they most likely originated from Scandinavia and that they died soon after arrival in Britain.
Published Agriculture linked to changes in age-independent mortality in North America


The transition to agriculture from hunting and gathering in pre-colonial North America led to changes in age-independent mortality, or mortality caused by factors that are not associated with age, according to a new study. The team found that the intensification of crop use occurred in two phases, the first of which led to a decline in human age-independent mortality, while the second is associated with a rise in it. The study is the first to tie patterns of age-independent mortality to food production.
Published Plague trackers: Researchers cover thousands of years in a quest to understand the elusive origins of the Black Death


Seeking to better understand more about the origins and movement of bubonic plague, in ancient and contemporary times, researchers have completed a painstaking granular examination of hundreds of modern and ancient genome sequences, creating the largest analysis of its kind.
Published Violence was widespread in early farming society


Violence and warfare were widespread in many Neolithic communities across Northwest Europe, a period associated with the adoption of farming, new research suggests. Of the skeletal remains of more than 2300 early farmers from 180 sites dating from around 8000 -- 4000 years ago to, more than one in ten displayed weapon injuries, bioarchaeologists found.
Published Mummified crocodiles provide insights into mummy-making over time


Crocodiles were mummified in a unique way at the Egyptian site of Qubbat al-Hawa during the 5th Century BC, according to a new study.
Published Marriage in Minoan Crete


An international team of researchers achieves completely new insights into Bronze Age marriage rules and family structures in Greece. Analyses of ancient genomes show that the choice of marriage partners was determined by one's own kinship.
