Researchers solve 2,000-year-old mystery of the shipworm      (via sciencedaily.com)     Original source 

They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.

Blood sausages and yak milk: Bronze Age cuisine of Mongolian nomads unveiled      (via sciencedaily.com)     Original source 

Bronze cauldrons were used by the inhabitants of the Mongolian steppe around 2,700 years ago to process animal blood and milk. This is shown by a protein analysis of archaeological finds from this period.

Crucial shift in River Nile's evolution during ancient Egypt discovered      (via sciencedaily.com)     Original source 

Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilization. Research reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.

Kinship and ancestry of the Celts in Baden-Württemberg, Germany      (via sciencedaily.com)     Original source 

The Celtic culture of the pre-Roman Iron Age in Western and Central Europe has left numerous traces to this day, not least in the form of enormous burial mounds and spectacular archaeological artifacts. Despite this rich legacy, much about this civilization remains hidden from us.

Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance?      (via sciencedaily.com)     Original source 

A new study has uncovered a diverse array of microorganisms within the hot waters of the Roman Baths, regularly listed among the UK's most popular tourist attractions. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

Safeguarding urban infrastructure from subsidence and liquefaction risks      (via sciencedaily.com)     Original source 

During an earthquake, soil can weaken through subsidence and liquefaction. These processes can cause buildings to collapse as the soil becomes unable to support their weight. Researchers have now developed a model that predicts soil-bearing strength and thickness to identify stable construction sites and reduce structural risks. Additionally, the model can also predict other soil conditions in real-time and function as an early-warning system to identify potential hazards.

Understanding the mechanisms for local amplification of 2024 tsunamis in Iida Bay      (via sciencedaily.com)     Original source 

Researchers uncover the unique mechanisms that resulted in severe tsunamis in Iida Bay caused by the 2024 Noto Peninsula Earthquake. The recent tsunamis in Iida Bay were locally amplified due to various factors, including ocean floor topology, the shape of the coastline, the location of coastal facilities, and seismic mechanisms associated with earthquakes, report scientists.

Ancient people hunted extinct elephants at Tagua Tagua Lake in Chile 12,000 years ago      (via sciencedaily.com)     Original source 

Thousands of years ago, early hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephants and take advantage of other local resources, according to a new study.

3,500-year-old Mycenaean armor was suitable for extended battle      (via sciencedaily.com)     Original source 

A 3,500-year-old suit of Mycenaean armour may have been used in battle -- and not just for ceremonial purposes as previously thought -- new research reveals.

'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes      (via sciencedaily.com)     Original source 

In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.

Excavation reveals 'major' ancient migration to Timor Island      (via sciencedaily.com)     Original source 

The discovery of thousands of stone artefacts and animal bones in a deep cave in Timor Island has led archaeologists to reassess the route that early humans took to reach Australia. Researchers dated and analysed the artefacts and sediment at the Laili rock shelter in central-north Timor-Leste, north of Australia, to pinpoint the arrival of the colonists.

Highly sensitive fiber optic gyroscope senses rotational ground motion around active volcano      (via sciencedaily.com)     Original source 

Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, Italy. A better understanding of the seismic activity in this highly populated area could improve risk assessment and might lead to improved early warning systems.

Pagan-Christian trade networks supplied horses from overseas for the last horse sacrifices in Europe      (via sciencedaily.com)     Original source 

Horses crossed the Baltic Sea in ships during the Late Viking Age and were sacrificed for funeral rituals. Studies on the remains of horses found at ancient burial sites in Russia and Lithuania show that they were brought overseas from Scandinavia utilizing expansive trade networks connecting the Viking world with the Byzantine and Arab Empires. Up to now, researchers had believed sacrificial horses were always locally-sourced stallions. But these results reveal horses from modern Sweden or Finland traveled up to 1,500 km across the Baltic Sea. The findings also show that the sex of the horse was not necessarily a factor in them being chosen for sacrifice, with genetic analysis showing one in three were mares.

Early arrival and expansion of palaeolithic people on Cyprus      (via sciencedaily.com)     Original source 

The patterns of dispersal of early humans across continents and islands are hotly debated, but researchers have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought. In examining the timing of the first human occupation of Cyprus, research found that large islands in the Mediterranean Sea were attractive and favorable destinations for palaeolithic peoples. These findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies.

Researchers show that slow-moving earthquakes are controlled by rock permeability      (via sciencedaily.com)     Original source 

A research group explores how the makeup of rocks, specifically their permeability -- or how easily fluids can flow through them -- affects the frequency and intensity of slow slip events. Slow slips' role in the earthquake cycle may help lead to a better model to predict when earthquakes happen.
