Breakthrough Study Discovers Ancient Mantle Flow Beneath Philippine Sea Plate

A collaborative study by Chinese and Japanese scientists has uncovered evidence of ancient lower mantle flow fields beneath the Philippine Sea Plate, offering new insights into the Earth’s deep interior dynamics and the widespread presence of seismic anisotropy in the lower mantle.Scientists from China and Japan have identified unique features of the flow field in the lower mantle. Through their study of seismic anisotropy in the upper section of the lower mantle beneath the Philippine Sea Plate, they discovered that the…

Scientists Have Discovered an Underwater Ancient Island Paradise in the South Atlantic Ocean

Samples were collected during expeditions conducted in 2018 by researchers affiliated with the University of São Paulo (Brazil) and the University of Southampton (UK). This dark-gray rock is a volcanic basalt deposit.

The researchers intend to further investigate its natural processes.Research conducted by scientists from the…

How Ancient Viral DNA Could Accelerate Neurodegeneration

Research suggests that endogenous retroviruses within the human genome could influence the development of neurodegenerative diseases by contributing to the spread of abnormal protein aggregates in the brain. Credit: SciTechDaily.comResearchers See Ancient Genes As Potential Targets for Dementia TreatmentGenetic remnants of viruses that are naturally present in the human genome could affect the development of neurodegenerative diseases. Researchers at DZNE come to this conclusion on the basis of studies on cell cultures.…

New archive of ancient human brains challenges misconceptions of soft tissue preservation

Fragments of brain from an individual buried in a Victorian workhouse cemetery (Bristol, UK), some 200 years ago. No other soft tissue survived among the bones, which were dredged from the heavily waterlogged grave. Credit: Alexandra L. Morton-Hayward Soft tissue preservation in the geological record is relatively rare, and except where deliberate intervention halts the process of decay (like embalming or freezing), the…

Inside the AI Competition That Decoded an Ancient Scroll and Changed Papyrology Forever

On a warm Saturday night at the end of August last year, Luke Farritor, an undergraduate at the University of Nebraska, was sitting alone in a corner at a house party in Omaha when his iPhone pinged. The music was booming, and Farritor, 21 years old at the time with a boyish face and black rectangular glasses, was surrounded by other students drinking and mingling. He opened the message. It was from Ben Kyles, a 45-year-old computer scientist and pianist from British Columbia, known to Farritor as “Hari Seldon”—Kyles’s…

Seismological study shows ancient lower mantle flow field under Philippine sea plate

Unlocking the climate secrets of North China with ancient tree rings

Overview of the study area. Credit: Journal of Geographical Sciences (2023). DOI: 10.1007/s11442-023-2187-6 A study published in the Journal of Geographical Sciences reveals a novel method for reconstructing historical warm season temperatures in North China. Utilizing the blue intensity (BI) of tree rings of Picea meyeri, researchers have developed a 281-year chronology, offering unprecedented insights into the region's…
