Archaeologists and primatologists have shown that stone tool using chimpanzees in West Africa have distinct and recognizable material cultures.

It isn't every day that we learn something that fundamentally changes how we understand our world. But for volcanologists across the globe, such a revelation has occurred.

Tiny crystals in ancient animal dung serve as key evidence in a new analysis suggesting the possibility that hunter-gatherers at Abu Hureyra, Syria, may have tended small numbers of animals just outside their dwellings between 12,800 and 12,300 years ago.

The question of what makes modern humans unique has long been a driving force for researchers. Comparisons with our closest relatives, the Neanderthals, therefore provide fascinating insights. The increase in brain size, and in neuron production during brain development, are considered to be major factors for the increased cognitive abilities that occurred during human evolution. However, while both Neanderthals and modern humans develop brains of similar size, very little is known about whether modern human and Neanderthal brains may have differed in terms of their neuron production during development. Researchers now show that the modern human variant of the protein TKTL1, which differs by only a single amino acid from the Neanderthal variant, increases one type of brain progenitor cells, called basal radial glia, in the modern human brain.

Scientists discover that a potential 'diamond factory' may have existed at Earth's core-mantle boundary for billions of years.

Using machine learning to sift through a decade's worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown fault structures in Oklahoma and Kansas.

A vast paleogenetic study reveals insights on migration patterns, the expansion of farming and language development from the Caucasus over western Asia and Southern Europe from the early Copper Age until the late middle ages.

A modern scientific analysis of ancient stone tools is challenging long-held beliefs about what caused radical change on the island of Crete, where the first European state flourished during the Bronze Age: the 'Minoan civilization.'

Research has established that there are traces of Neandertal DNA in the genome of modern humans. Now an exploratory study that assessed the facial structure of prehistoric skulls is offering new insights, and supports the hypothesis that much of this interbreeding took place in the Near East -- the region ranging from North Africa to Iraq.

New research reveals more about the magnitude of January eruption, as researchers call for better preparedness The eruption of the Hunga Tonga-Hunga Ha'apai volcano in January created an initial wave 90 meters high -- almost the height of the Statue of Liberty (93m). Tsunami expert calls for better warning systems to detect volcanic eruptions, saying systems are '30 years behind' comparable earthquake detection tools.

Researchers say ubiquitous evidence for ongoing geological carbon sequestration in mantle rocks in the creeping sections of the San Andreas Fault is one underlying cause of aseismic creep along a roughly 150 kilometer-long SAF segment between San Juan Bautista and Parkfield, California, and along several other fault segments.

A new article assesses the impact of hydraulic fracturing on seismic hazards like micro-earthquakes, an important issue for the safety of workers and the continuation of mining operations.

A new study into the multipurpose uses of boomerangs has highlighted the hardwood objects were used to shape the edges of stone tools used by Australian Indigenous communities.  The research demonstrated how boomerangs could function as lithic (or stone) tool retouchers by investigating the use-wear generated on the boomerangs' surfaces during retouching activities. It was found that these use-wear impacts on boomerangs comparable to those observed on Paleolithic bone retouching tools, which date back to more than 200,000 years ago.

Using single calcite crystals with varying surface roughness allows engineers to simplify the complex physics that describes fault movement. Researchers now show how this simplification may lead to better earthquake prediction.

Researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.

Beaver fur was a symbol of wealth and an important trade item in 10th Century Denmark, according to a new study.

While many U.S. policy makers are calling for reshoring and nearshoring to combat trade disruptions caused by COVID-19, new research suggests retrenchment of global supply chains is unlikely to happen in the post-pandemic context.

For the first time, researchers successfully sequenced the genome of ancient human fossils from the Late Pleistocene in southern China. The data suggests that the mysterious hominin belonged to an extinct maternal branch of modern humans that might have contributed to the origin of Native Americans.

A novel three-dimensional model of the fluid stored deep in Earth's crust along the Cascadia Subduction Zone provides new insight into how the accumulation and release of those fluids may influence seismic activity in the region.

Using data from the eruption of the underwater volcano near Tonga in 2022, researchers used disturbances in Earth's upper atmosphere to track the airwaves that cause tsunami. Their findings may lead to speedier predictions of these giant waves.
