New archive of ancient human brains challenges misconceptions of soft tissue preservation      (via sciencedaily.com)     Original source 

A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.

New simpler and cost-effective forensics test helps identify touch DNA      (via sciencedaily.com)     Original source 

Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.

Experiment captures why pottery forms are culturally distinct      (via sciencedaily.com)     Original source 

Potters of different cultural backgrounds learn new types differently, producing cultural differences even in the absence of differential cultural evolution. The research has implications for how we evaluate the difference of archaeological artifacts across cultures.

Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices      (via sciencedaily.com)     Original source 

While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. A recent study contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs -- their temple food ingredients, timing of ceremonies, and plants for temple decoration.

Did neanderthals use glue? Researchers find evidence that sticks      (via sciencedaily.com)     Original source 

Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought.

This tiny, tamper-proof ID tag can authenticate almost anything      (via sciencedaily.com)     Original source 

A cryptographic tag uses terahertz waves to authenticate items by recognizing the unique pattern of microscopic metal particles that are mixed into the glue that sticks the tag to the item's surface.

Scandinavia's first farmers slaughtered the hunter-gatherer population, study finds      (via sciencedaily.com)     Original source 

Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is now Denmark.

Innovation in stone tool technology involved multiple stages at the time of modern human dispersals      (via sciencedaily.com)     Original source 

A new study illuminates the cultural evolution that took place approximately 50,000 to 40,000 years ago, coinciding with the dispersals of Homo sapiens across Eurasia. The insights gleaned from their examination of stone tool technology challenge the widely held notion of a rapid cultural and technological 'revolution' that enabled anatomically modern humans to surpass Neanderthals and other archaic humans. Instead, the research suggests a nuanced evolutionary process, unfolding gradually over an extended period, with changes occurring at various times. These findings challenge the conventional theory on the timing and nature of cultural transitions during this pivotal period in human history.

Thailand's Iron Age Log Coffin culture      (via sciencedaily.com)     Original source 

A mortuary practice known as Log Coffin culture characterizes the Iron Age of highland Pang Mapha in northwestern Thailand. Between 2,300 and 1,000 years ago, individuals were buried in large wooden coffins on stilts, mostly found in caves and rock shelters.

A sleeker facial recognition technology tested on Michelangelo's David      (via sciencedaily.com)     Original source 

Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report on a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of Michelangelo's David just as well as an existing smartphone system.

Prehistoric mobility among Tibetan farmers, herders shaped highland settlement patterns, cultural interaction, study finds      (via sciencedaily.com)     Original source 

Using advanced geospatial modeling to compare environmental and archaeological evidence, researchers found evidence that connects ancient mobility and subsistence strategies to cultural connections forged among Tibetan farmers and herders in the Bronze and Iron Ages -- adding to understanding of how and why ancient communities built social relationships and cultural identities across the extreme terrain in Tibet.

Neanderthals and humans lived side by side in Northern Europe 45,000 years ago      (via sciencedaily.com)     Original source 

Archaeologists have debated whether Neanderthals or modern humans made stone tools that are found at sites across northern Europe and date from about 40,000 years ago. A new excavation at one site in Germany turned up 45,000-year-old bone fragments that, when analyzed for mitochondrial DNA, proved to be from Homo sapiens. This is the earliest evidence that modern humans overlapped with Neanderthals in northwest Europe, thousands of years before Neanderthals went extinct.

Excavated dolmen in Sweden one of the oldest in Scandinavia      (via sciencedaily.com)     Original source 

The first analysis results now confirm that the grave in Tiarp is one of the oldest stone burial chambers in Sweden. The researchers noted that some parts of the people buried in the grave are missing, such as skulls and thigh bones, posing intriguing questions for archaeologists.

Woolly mammoth movements tied to earliest Alaska hunting camps      (via sciencedaily.com)     Original source 

Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Isotopic data, along with DNA from other mammoths at the site and archaeological evidence, indicates that early Alaskans likely structured their settlements to overlap with areas where mammoths congregated. Those findings, highlighted in the new issue of the journal Science Advances, provide evidence that mammoths and early hunter-gatherers shared habitat in the region. The long-term predictable presence of woolly mammoths would have attracted humans to the area.
