Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia's Greater Angkor region was home to 700,000-900,000 people. The new estimate, made possible by a study designed at the University of Oregon, is the first for the entire 3,000-square-kilometer low-density region.
Systemic inequalities mean that low-income households in London are more likely to be exposed to higher levels of indoor air pollution, according to a report by UCL researchers. The biggest factors are the quality of housing and the characteristics of the surrounding environment, taking location and levels of outdoor air pollution into account - factors beyond occupants' control.
How did people living in the Bronze Age manage their finances before money became widespread? Researchers from the Universities of Göttingen and Rome have discovered that bronze scrap found in hoards in Europe circulated as a currency. These pieces of scrap - which might include swords, axes, and jewellery broken into pieces - were used as cash in the late Bronze Age, and in fact complied with a weight system used across Europe. Results were published in Journal of Archaeological Science.
In the 150 years since Charles Darwin speculated that humans originated in Africa, the number of species in the human family tree has exploded, but so has the level of dispute concerning early human evolution. A new review looks at the major discoveries in hominin origins since Darwin's works and argues that fossil apes can inform us about essential aspects of ape and human evolution, including the nature of our last common ancestor.
A new study reveals Australia's 'black summer' of bushfires was covered by the world's media as an environmental and ecological issue with global consequences, while in Australia the toll on ordinary people remained the visual front-page focus.
A new study investigated the impact of Airbnb's algorithm on racial disparities among Airbnb hosts. Adopting the tool narrowed the revenue gap between White and Black hosts considerably, but because far fewer Black hosts used the algorithm, the revenue gap between White and Black hosts actually increased after the tool's introduction.
As in many other socially-living species, humans form coalitions to gain advantage in conflicts or to seek or maintain social status. However, studying coalition formation in human societies is complicated by the formal institutions - such as businesses, courts, and governments - that structure social relationships and conflict resolution. But even in small-scale human societies with a relative lack of such formal institutions, there is scant research on the details of coalition formation.
Researchers at Singapore-MIT Alliance for Research and Technology (SMART) and Massachusetts Institute of Technology (MIT) conducted a case study in the first-mile mobility market from origins to subway stations in Tampines, Singapore, to find out the impact of competition between public transit and shared autonomous vehicles. The study revealed that with the right conditions, the competition can be beneficial for both parties and improve overall transport systems.
The first civilisations to build monumental palaces and urban centres in Europe are more genetically homogenous than expected, according to genomes gathered from archaeological sites around the Aegean. Individuals from the northern Aegean were considerably different by the Middle Bronze Age, sharing half their ancestry with people from the Pontic-Caspian steppe. These populations were highly similar to present-day Greeks. This supports theories that Proto-Greek and Indo-European languages originated in Anatolia or the Pontic-Caspian Steppe region.
A new study featured on the 6 May cover of Nature by an international team of researchers details the earliest modern human burial in Africa. The remains of a 2.5 to 3 year-old child were found in a flexed position, deliberately buried in a shallow grave directly under the sheltered overhang of the cave. The interment at Panga ya Saidi joins increasing evidence of early complex social behaviours in Homo sapiens.
