A hunter-gatherer settlement in southeastern Siberia has yielded the earliest known evidence of a plague epidemic, combining archaeology and ancient DNA analysis.
The epidemic dates back around 5,500 years to southeastern Siberia.
Evidence combines archaeology with genetic sequencing of Yersinia pestis.
The find pushes back the known chronology of plague by several hundred years.
A new study suggests that quality espresso could be brewed without heating water to high temperatures, potentially upending a core assumption of coffee science.
Traditional espresso relies on hot pressurised water to extract flavour from ground coffee.
Researchers propose an extraction method that works without high water temperatures.
A practical application could cut the energy use of household and commercial coffee machines.
Archaeologists have found a prehistoric structure close to Stonehenge in southern England that may have served as an architectural blueprint for the 5,000-year-old stone circle.
The newly found structure may have served as an early model for Stonehenge, archaeologists say.
The Wiltshire monument is around 5,000 years old and its exact purpose remains disputed.
The discovery points to a gradual design process rather than a single construction plan.
The European Parliament approved updated rules on new genomic techniques (NGT) in agriculture, paving the way for disease- and drought-resistant plant varieties.
The European Parliament adopted new legislation on NGT genomic techniques in farming.
Edited plants could be more resistant to disease, pests and drought.
Environmentalists demand stronger traceability and product labelling rules.
