How surgical global health programs are affected by the COVID pandemic and why global surgical outreach models may need to be rehashed are discussed in this article.
The first underwater Aboriginal archaeological sites have been discovered off northwest Australia dating back thousands of years ago when the current seabed was dry land. Aboriginal artefacts discovered off the Plibara coast in Western Australia were discovered through a series of archaeological and geophysical surveys in the Dampier Archipelago, as part of the Deep History of Sea Country Project, funded through the Australian Research Council's Discovery Project Scheme.
Ancient submerged Aboriginal archaeological sites await underwater rediscovery off the coast of Australia, according to a study published July 1, 2020 in the open-access journal PLOS ONE by Jonathan Benjamin of Flinders University, Adelaide, Australia and colleagues.
A research team from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) has now unlocked the secrets of true coloration in the 99-million-year-old insects.
Reservoirs in the heart of an ancient Maya city were so polluted with mercury and algae that the water likely was undrinkable. ?Researchers from the University of Cincinnati found toxic levels of pollution in two central reservoirs in Tikal, an ancient Maya city that dates back to the third century B.C. in what is now northern Guatemala. UC's findings suggest droughts in the ninth century likely contributed to the depopulation and eventual abandonment of the city.
Before the arrival of European colonizers, the Amazonian Indigenous peoples cultivated their food - cassava, corn, pineapple, peppers and squash, among other things. The food of the ancient civilizations of the Amazon also largely consisted of the fruits of palm and Brazilian nut trees. The protection and management of trees across generations have affected the diversity of the rainforest right up until the present time.
People in what is now Washington State were smoking Rhus glabra, a plant commonly known as smooth sumac, more than 1,400 years ago. The discovery, made by a team of Washington State University researchers, marks the first-time scientists have identified residue from a non-tobacco plant in an archeological pipe.
Sledge dogs are much older and have adapted to Arctic conditions much earlier than previously thought. In a new study from the QIMMEQ project, researchers from the University of Copenhagen show that ancestors of modern sledge dogs have worked and lived with humans for over 9,500 years.
Today's modern cities, from Denver to Dubai, could learn a thing or two from the ancient Pueblo communities that once stretched across the southwestern United States. For starters, the more people live together, the better the living standards.
Innovation by ancient farmers to improve soil fertility continues to have an impact on the biodiversity of the Amazon, a major new study shows.
