Chromium steel - similar to what we know today as tool steel - was first made in Persia, nearly a millennium earlier than experts previously thought, according to a new study led by UCL researchers.
Ancient hunters stayed in the coldest part of Northern Europe rather than migrating to escape freezing winter conditions, archaeologists have found.
A Dartmouth-led study using multisensor drones has revealed a large circular earthwork at what may be Etzanoa, an archaeological site near Wichita, Kansas. Archaeologists speculate that the site was visited by a Spanish expedition, led by Juan de Oñate, a controversial conquistador, in 1601. The earthwork may be the remains of a so-called "council circle," as it is similar to several other circular earthworks in the region, according to the study's findings published in American Antiquity.
A new study led by the University of Bristol and Swansea University has revealed the size of the legendary giant shark Megalodon, including fins that are as large as an adult human.
Among the many winter survival strategies in the animal world, hibernation is one of the most common. According to new research, this type of adaptation has a long history. In a paper published in the journal Communications Biology, scientists at Harvard University and the University of Washington report evidence of a hibernation-like state in an animal that lived in Antarctica during the Early Triassic, some 250 million years ago.
Researchers in South Africa's Border Cave have found evidence that people have been using grass bedding to create comfortable areas for sleeping and working on at least 200 000 years ago.
From 2007 to 2009, a devastating yellow fever virus outbreak nearly decimated brown and black and gold howler monkey populations at El Parque El Piñalito in northeastern Argentina. An international research team tested if howlers who survived the outbreak had any genetic variations that may have kept them alive. In brown howlers, they found two mutations on immune genes that resulted in amino acid changes in the part of the protein that detects the disease.
Archaeologists at The Australian National University have found the earliest evidence of Indigenous communities cultivating bananas in Australia. The evidence of cultivation and plant management dates back 2,145 years and was found at Wagadagam on the tiny island of Mabuyag in the western Torres Strait. The research is led by a First Australian author. His work makes a statement that goes beyond academia.
Stone fluted points dating back some 8,000 to 7,000 years ago, were discovered on archaeological sites in Manayzah, Yemen and Ad-Dahariz, Oman. Until now, the prehistoric technique of fluting had been uncovered only on 13,000 to 10,000-year-old Native American sites.
A new paper published in the journal PLOS ONE examines fluted projectile points from southern Arabia, detailing production methods and technical aspects that indicate differences in function from the technology of the Americas, despite similarities in form. Findings from experimentation and comparative analysis suggest that highly-skilled, convergent technologies can have varying anthropological implications.
