The prehistoric collapse of Easter Island's monument-building society did not occur as long thought, according to a fresh look at evidence by researchers at four institutions. The decline did not begin until the arrival of Europeans.
Scientists from the University of Granada, thanks to microtomography techniques, reveal secret, and until now unknown, aspects of tunnel construction strategies, and how to exploit the fruit, in addition to the internal structures of a tiny beetle known as the 'coffee berry borer.'
A new skeleton discovered in the submerged caves at Tulum sheds new light on the earliest settlers of Mexico, according to a study published Feb. 5, 2020, in the open-access journal PLOS ONE by Wolfgang Stinnesbeck from Universität Heidelberg, Germany.
A new study shows that ancient Siberian hunters created heat resistant pots so that they could cook hot meals - surviving the harshest seasons of the ice age by extracting nutritious bone grease and marrow from meat.
After sequencing the Neanderthal genome, scientists discovered all present day non-African individuals carry some Neanderthal ancestry in their DNA. Now, researchers at Princeton University present evidence of Neanderthal ancestry in African populations too, and its origin provides new insights into human history.
Most nuclear data measurements are performed at accelerators large enough to occupy a geologic formation a kilometer wide. But a portable device that can reveal the composition of materials quickly on-site would greatly benefit cases such as in archaeology and nuclear arms treaty verification. Research published this week used computational simulations to show that with the right geometric adjustments, it is possible to perform neutron resonance transmission analysis in a device just 5 meters long.
Before they can get started at their field site - a giant cave studded with stalactites, stalagmites and human artifacts -- 15 undergraduate students must figure out how to use their virtual hands and tools. They also must learn to teleport. (Video available)
An analysis of four ancient skulls found in Mexico suggests that the first humans to settle in North America were more biologically diverse than scientists had previously believed. The skulls were from individuals who lived 9,000 to 13,000 years ago, in the late Pleistocene and early Holocene eras.
Ancient skulls from the cave systems at Tulum, Mexico, suggest that the earliest populations of North America may have already had a high level of morphological diversity, according to a study published Jan. 29, 2020 in the open-access journal PLOS ONE by Mark Hubbe from Ohio State University, USA, Alejandro Terrazas Mata from Universidad Nacional Autónoma de México, Mexico, and colleagues.
In southern Africa, dinosaurs and synapsids, a group of animals that includes mammals and their closest fossil relatives, survived in a 'land of fire' at the start of an Early Jurassic mass extinction, according to a study published Jan. 29, 2020 in the open-access journal PLOS ONE by Emese M. Bordy of the University of Cape Town and colleagues.
