Magma beneath long-dormant Mount Edgecumbe volcano in Southeast Alaska has been moving upward through Earth's crust, according to research the Alaska Volcano Observatory rapidly produced using a new method.

In medieval Norway, high status individuals tended to be taller and to have stronger bones, possibly as a result of a favorable lifestyle, according to a new study.

Researchers have managed to sequence multiple individuals from a remote Neanderthal community in Siberia. Among these thirteen individuals, the researchers identified multiple related individuals -- among these a father and his teenage daughter. The researchers were also able to use the thirteen genomes to provide a glimpse into the social organization of a Neanderthal community. They appear to have been a small group of close relatives, consisting of ten to twenty members, and communities were primarily connected through female migration.

Carvings in boab trees are as significant as rock art for Indigenous Australians. Now, there is a race against time to document the ancient art in the bark of boabs before the remarkable heritage trees die.

Geneticists have discovered a previously unknown lineage of wild goats over ten millennia old. The new goat type, discovered from genetic screening of bone remains and referred to as 'the Taurasian tur', likely survived the Last Glacial Maximum (the ice age), which stranded their ancestors in the high peaks of the Taurus Mountains in Turkey where their remains were found.

The Plinian eruption of Mount Vesuvius around 4,000 years ago -- 2,000 years before the one that buried the Roman city of Pompeii -- left a remarkably intact glimpse into Early Bronze Age village life in the Campania region of Southern Italy. The village offers a rare glimpse into the lives of the people who lived there, and the degree of preservation led the researchers to pinpoint the timing of the eruption, based on archaeobotanical record.

With the help of geomagnetic surface surveys and subsequent hands-on digging, an excavation team has revealed new insights into the area in which the caliph's palace of Khirbat al-Minya was built on the shores of the Sea of Galilee. According to these findings, there had already been a settlement occupied by Christian or Jewish inhabitants in the immediate vicinity long before the palace was built.

It was the money that grew on trees. Said to be a gift from the gods, cacao for the ancient Maya was considered sacred, used not only as currency, but in special ceremonies and religious rituals. It's the progenitor plant of chocolate, and notions of luxury are embedded in its lore.

Interdisciplinary research in southern Ethiopia enabled the deciphering of eastern Africa's climatic heartbeat and shows how key phases of climate change influenced human evolution, dispersal and innovation.

Researchers have identified climate-driven changes to food availability as a factor behind dramatic historical events that led the oasis city of Palmyra in Syria to its ultimate demise.

In the largest early-medieval population study to date, an interdisciplinary team consisting of geneticists and archaeologists analyzed over 400 individuals from ancient Britain, Ireland, Germany, Denmark and the Netherlands. The results show in detail one of the largest population transformations in the post-Roman world.

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.

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.

While funding is pumped into preventing low-probability scenarios such as asteroid collision, the far more likely threat of a large volcanic eruption is close to ignored -- despite much that could be done to reduce the risks, say researchers.
