A Stone Age skeleton found in a peat bog in northwest Denmark has been analysed to flesh out in stunning detail the ancient person’s life and death. New analysis of the remains is published in the journal PLOS ONE.
An international team of scientists reports that cave art at a site in Patagonia is the oldest of its type ever found in South America. In their study, published in the journal Science Advances, the group conducted radiocarbon dating of the material used to create the art thousands of years ago.
After coming to what is now Serranía de la Lindosa, an archaeological site on the northern edge of the Colombian Amazon, these early Americans lived in rock shelters, fashioned stone tools, hunted and gathered and created massive displays of rock art, according to a new study, published in the March issue of the journal Quaternary Science Reviews.
A team of philologists, chemists, environmental physicists and engineers affiliated with several institutions across Europe has found evidence of an undeciphered script on wooden tablets created on Easter Island that represents an independent writing system. Their paper is published in the journal Scientific Reports.
A concentrated cannabis extract has shown “remarkable” potential to kill off the most dangerous type of skin cancer. The study was published in Cells.
