Published Toward a code-breaking quantum computer
(via sciencedaily.com) Original source Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography.
Published To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say
(via sciencedaily.com) Original source 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 Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Impact of 700 years of Inuvialuit subsistence hunting on beluga whales
(via sciencedaily.com) Original source An international team of researchers analyzed beluga whale bones retrieved from archaeological sites in the Mackenzie Delta, Northwest Territories, Canada, to shed light on the sustainability of centuries of Inuvialuit beluga whale subsistence harvests.
Published Great Scott! Stonehenge's Altar Stone origins reveal advanced ancient Britain
(via sciencedaily.com) Original source New research has revealed Stonehenge's monumental six-ton Altar Stone, long believed to originate from Wales, actually hails from Scotland.
Published House call: A new study rethinks early Christian landmark
(via sciencedaily.com) Original source 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 Carvings at ancient monument may be world's oldest calendars
(via sciencedaily.com) Original source 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 Demographics of north African human populations unravelled using genomic data and artificial intelligence
(via sciencedaily.com) Original source 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 Hunter-gatherers kept an 'orderly home' in the earliest known British dwelling
(via sciencedaily.com) Original source Archaeological evidence from the world-famous Mesolithic site of Star Carr in North Yorkshire has shown that hunter-gatherers likely kept an orderly home by creating 'zones' for particular domestic activities.
Published Evidence for butchery of giant armadillo-like mammals in Argentina 21,000 years ago
(via sciencedaily.com) Original source Cut marks on fossils could be evidence of humans exploiting large mammals in Argentina more than 20,000 years ago, according to a new study.
Published 'A history of contact': Geneticists are rewriting the narrative of Neanderthals and other ancient humans
(via sciencedaily.com) Original source Using genomes from 2,000 living humans as well as three Neanderthals and one Denisovan, an international team mapped the gene flow between the hominin groups over the past quarter-million years.
Published The plague may have caused the downfall of the Stone Age farmers
(via sciencedaily.com) Original source Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds
(via sciencedaily.com) Original source A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published How researchers are using digital city-building games to shape the future
(via sciencedaily.com) Original source Researchers have come up with exciting and sophisticated new mapping technology enabling future generations to get involved in creating their own future built landscape. They say that planners are missing a real trick when it comes to encouraging and involving the public to help shape their own towns, cities and counties for the future. They also say that games platforms can be used to plan future cities and also help the public immerse themselves in these future worlds.
Published The beginnings of fashion
(via sciencedaily.com) Original source A team of researchers suggest that eyed needles were a new technological innovation used to adorn clothing for social and cultural purposes, marking the major shift from clothes as protection to clothes as an expression of identity.
Published First case of Down syndrome in Neanderthals documented in new study
(via sciencedaily.com) Original source A new study documents the first case of Down syndrome in Neanderthals and reveals that they were capable of providing altruistic care and support for a vulnerable member of their social group.
Published Origins of cumulative culture in human evolution
(via sciencedaily.com) Original source Cumulative culture -- the accumulation of technological modifications and improvements over generations -- allowed humans to adapt to a diversity of environments and challenges. But, it is unclear when cumulative culture first developed during hominin evolution. A new study concludes that humans began to rapidly accumulate technological knowledge through social learning around 600,000 years ago.
Published New research finds biases encoded in language across cultures and history
(via sciencedaily.com) Original source Researchers share evidence that people's attitudes are deeply woven into language and culture across the globe and centuries.
Published Ancient Syrian diets resembled the modern 'Mediterranean diet'
(via sciencedaily.com) Original source Thousands of years ago, people in ancient Syria likely ate mostly grains, grapes, olives and a small amount of dairy and meat -- similar to today's 'Mediterranean diet,' according to a new study.
