An important new study argues that inconsistent weather and spotty resources prevented enduring inequality from emerging in some early hunter-gatherer societies. By contrast, pre-colonial indigenous societies of the northwest coast of North America and the American southeast are notable for their marked social hierarchies, including chiefdoms and, in some cases, slavery.
"The conditions for the development of marked inequality [in North America] included reliable and prolific resources such as salmon, relatively high population densities, and the defense of territories and their resources," explains Ian Keen (Australian National University).
In the forthcoming issue of Current Anthropology, Keen compares complex hunter-gatherer societies in North America and Australia. Despite considerable variation in environments and resources, nowhere in Australia did "enduring inequality" such as ranked lineage or chiefly office prevail. However, Australian Aboriginal societies on the tropical northern coast were marked by "transient inequality" arising from high levels of polygyny, with some older men claiming more than twenty wives.

Some brain tumors may respond to immunotherapy, new study suggests

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
