ANU and Uni of Melbourne Archaeologists have discovered 15 new sites in Laos containing more than one hundred 1000-year-old massive stone jars possibly used for the dead.
Older forests in eastern North America are less vulnerable to climate change than younger forests - particularly for carbon storage, timber production, and biodiversity - new University of Vermont research finds.
Coral reef experts from around the world are calling for an urgent re-evaluation of our climate goals in the light of increasing evidence of the unprecedented speed of change to these fragile ecosystems. Coral reefs, which have functioned relatively unchanged for some 24 million years, are now going through profound changes in their make-up.
An international team of researchers has analyzed human remains from 21 archaeological sites to learn more about the impact and evolution of the plague-causing bacterium Yersinia pestis during the first plague pandemic (541-750 AD). In a study published in PNAS, the researchers reconstructed 8 plague genomes from Britain, Germany, France, and Spain and uncovered a previously unknown level of diversity in Y. pestis strains. Additionally, they found the first direct genetic evidence of the Justinianic Plague in the British Isles.
One of the world's most important plant families has a history extending much farther south than any live or fossil specimen previously recorded, as shown by chinquapin fruit and leaf fossils unearthed in Patagonia, Argentina, according to researchers.
New research on the evolutionary relationships between tree sloths and their extinct giant relatives is challenging decades of widely accepted scientific research.
Earlier in the week, NOAA's National Hurricane Center was monitoring a low-pressure system in the Gulf of Campeche that has now moved along the Texas and Louisiana coastlines, bringing heavy rainfall. On June 5, NASA used a constellation of satellites to estimate that rainfall.
Strange ring-shaped objects in a Bronze Age hillfort site represent a unique form of cereal-based product, according to a study published June 5, 2019, in the open-access journal PLOS ONE by Andreas G. Heiss of the Austrian Archaeological Institute (ÖAW-ÖAI) and colleagues.
Since the mass production of plastics began in the 1940s, the versatile polymers have spread rapidly across the globe. Although plastics have made life easier in many ways, disposing of the materials is a growing problem.
Fecal transplants from young to aged mice can stimulate the gut microbiome and revive the gut immune system, a study by immunologists at the Babraham Institute, Cambridge, has shown. The research is published in the journal Nature Communications today.
LAWRENCE -- A clutch of marine fossil specimens unearthed in northern Portugal that lived between 470 and 459 million years ago is filling a gap in understanding evolution during the Middle Ordovician period.
A new archaeological site discovered by an international and local team of scientists working in Ethiopia shows that the origins of stone tool production are older than 2.58 million years ago. Previously, the oldest evidence for systematic stone tool production and use was 2.58 to 2.55 million years ago.
GAINESVILLE, Fla. --- An ancient, cosmopolitan lineage of plants is shaking up scientists' understanding of how quickly species evolve in temperate ecosystems and why.
Irvine, Calif. - Nearly one-fifth of the world's population lives in a stressed water basin where the next climate change-driven incident could threaten access to an essential resource for agriculture, industry and life itself, according to a paper by University of California, Irvine researchers and others, published today in Nature Sustainability.
URBANA, Ill. - Illinois wheat growers, take heart. A new University of Illinois study shows no evidence of a highly toxic Fusarium head blight (FHB) variant, known as NA2, in the wheat-growing region of the state. The study also reinforces the effectiveness of wheat resistance to the fungal disease.
