South African rock shelter artifacts show early humans colonized inland areas

Science
March 31 (UPI) -- Archaeological evidence from a rock shelter in South Africa suggests early humans colonized a variety of environments, including inland settings, undermining theories linking the origins of our species to the coast. For generations, the rock shelter on Ga-Mohana Hill, positioned at the edge of South Africa's Kalahari Desert, has served as a spiritual site for local people. But until now, researchers weren't sure how long the shelter has been used by humans. Advertisement To find out, archaeologists excavated a collection of white calcite crystals and ostrich eggshell fragments, thought to be used as water vessels. Researchers detailed their excavation and analysis efforts in a new paper, published Wednesday in the journal Nature. "The crystals point towards spiritual or...

Subsea pipelines offer shelter to important commercial fish species in Australia

Science
June 12 (UPI) -- For conservationists and environmentalists, pipelines and the oil they carry are mostly viewed as a threat to ecological health. But new research suggests they serve as a safe haven for important commercial fish species off the coast of northwest Australia.The North West Shelf, which lies off the coast of Western Australia, features an array of gas wells, subsea pipelines and other kinds of underwater infrastructure necessary to support oil and gas exploration in the region.Oil and gas companies regularly use remote operated vehicles, or ROVs, to monitor their pipelines. Researchers at the University of Western Australia used video footage from industry submersibles to survey fish diversity and abundance around pipelines at varying depths.Their analysis revealed a surprisi...
