Humans news stories

A recent study, published in the Journal of Archaeological Science: Reports, presents and discusses the earliest burial site in Patagonia and one of the earliest pieces of evidence of Early Holocene human settlement on the South American Atlantic coast.

There’s a new contender for the universe’s earliest first-generation stars. A bright clump seen about 450 million years after the Big Bang has the chemical hallmarks of first-generation stars — notably that it appears to have no elements heavier than helium. This identification, reported in a trio of papers submitted on March 20 to arXiv.org, pushes the evidence for these pristine stars much earlier than for previous candidates.

A single dose of the psychedelic compound psilocybin, when paired with behavioral counseling, helped smokers quit at substantially higher rates than a standard nicotine patch paired with the same counseling. The results suggest that psychedelic treatments might offer a highly effective new approach for people struggling to overcome tobacco addiction. The findings were recently published in the journal JAMA Network Open.

The exact origin of bread wheat (Triticum aestivum) is still a mystery, but researchers believe they are edging closer to the source of one of the most important food staples worldwide. Using genetic studies and ancient plant remains, an international team of scientists has narrowed the location and timeline to the Neolithic period(around 8,000 years ago) in Georgia, in the South Caucasus. They present their findings in a paper published in the journal Proceedings of the National Academy of Sciences.

There’s been a lot of buzz in recent years about bee cognition, but not all scientists are convinced. Now, new research has added a fresh ingredient to the mix: Accounting for how bees actually see the world, rather than relying on human assumptions…And guess what? The bees still seem to be able to count.The research has been published in the Proceedings of the Royal Society B: Biological Sciences.

In 1857, the German anatomist Hermann Schaaffhausen analysed a human fossil with “an extraordinary form”… The remains were to become known as the world’s first Neanderthal, and from the very start, Schaaffhausen decided the skull was at a “low stage of development”.For more than a century, that stigma has stuck around. Even today, a commonly accepted hypothesis is that humans outsurvived Neanderthals because of our better brains. An international team of anthropologists has now found evidence to the contrary. The study was published in PNAS.

Paving roads in the Amazon rainforest has long brought deforestation that threatens the people who live there. The same roadwork, however, has also allowed archaeologists to get glimpses of the region’s past long before Europeans arrived to reshape it.

On April 18, President Donald Trump signed an executive order intended to accelerate the development of psychedelic drugs as medical treatments. The order calls for the Food and Drug Administration (FDA) to give expedited consideration to psychedelics that meet certain criteria. It also calls for the Department of Health and Human Services to direct $50 million to match investments made by state governments into researching psychedelics as treatments for mental-health conditions.

New genetic results reveal a previously unknown wave of people settled in South America 1,300 years ago, and that Indigenous Americans carry remnants of a “ghost lineage.” The study was published Wednesday (April 22) in the journal Nature.

Members of the Atapuerca Research Team from the Institut Català de Paleoecologia Humana i Evolució Social (IPHES), the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), the University of Burgos, and the Center Européen de Recherche et d’Enseignement des Géosciences de l’Environnement (CEREGE) are involved in a study published in Quaternary Science Reviews reporting the earliest known evidence of the classic Acheulean in the Iberian Peninsula.

In our research, published today in Current Biology, we show that when some animals spot a predator, they issue a warning cry that is picked up by others and spread through the rainforest canopy. For a time, different species are linked into a shared information network, and parts of the forest briefly fall silent.

An international study published in Current Biology presents the results of the analysis of ancient mitochondrial DNA obtained from eight Neanderthal teeth discovered in Stajnia Cave, Poland. For the first time, the research reconstructs the genetic profile of a small group of Neanderthals from the same site, north of the Carpathians, who lived during the same ancient chronological phase.

The recent discovery of 12,000-year-old dice, published in American Antiquity, sheds new light on the playfulness of human societies in the deep past…The recognition of these artifacts as dice pushes back the material evidence for human play by thousands of years, which Madden interprets as evidence of games of chance and gambling. He believes that his study shows that Native Americans were gambling with dice 6,000 years earlier than anyone else.

The growth of the human population has not always been a smooth ride, but has been punctuated by some strange fluctuations. At multiple points in our history, populations have dramatically imploded. One such period occurred during the Neolithic, around 5,000 years ago, when communities collapsed across parts of Europe. The research has been published in Nature Ecology & Evolution.

Nearly 780,000-year-old charcoal fragments found at the Gesher Bnot Ya’akov archaeological site in northern Israel show that early humans had a higher level of intelligence than previously thought, according to a new study published in Quaternary Science Reviews.

Archaeologists working at the ancient settlement of Stăuceni-“Holm” in northeastern Romania have uncovered a mega-structure measuring 350 square meters dating back about 6,000 years. Their paper was published in PLOS One.
