The survival of PCR-amplifiable DNA in cow leather

We have investigated the survival of PCR-amplifiable mitochondrial and nuclear DNA in a small number of modern and medieval bovine leather samples. The results of this preliminary investigation demonstrate that, while no nuclear DNA can be PCR-amplified from any of the specimens, mitochondrial DNA can be amplified from all samples. To investigate this contrasting pattern of DNA survival further, we have vegetable-tanned cow skin in our own laboratory, and directly assayed the survival of PCR-amplifiable mitochondrial and nuclear DNA at each step of the process. The results indicate that nuclear DNA is reduced to sub-amplifiable levels as a result of the tanning baths, whereas amplifiable mitochondrial DNA survives the complete process. Our results suggest that old and archaeological bovine leather may represent a useful source of genetic information, although this information will most likely be limited to that which can be gained from mitochondrial DNA.     

Platform Capitalism’s Hidden Abode: Producing Data Assets in the Gig Economy

In this article, we argue that the governance of gig work under conditions of financialised platform capitalism is characterised by a process that we call “dual value production”: the monetary value produced by the service provided is augmented by the use and speculative value of the data produced before, during, and after service provision. App-governed gig workers hence function as pivotal conduits in software systems that produce digital data as a particular asset class. We reflect on the production of data assets and the unequal distribution of opportunities for their valorisation, after which we survey a number of strategies seeking data-centric worker empowerment. These strategies, we argue, are crucial attempts to push back against platform capitalism’s domination, bankrolled by what we term “meta-platforms”. Ultimately, it is the massive wealth and synergetic capacities of meta-platforms that constitute the most formidable obstacle to worker power and social justice in increasingly data-driven societies.

New excavations at the Barbar Temple, Bahrain

In 2004 excavations at the Barbar Temple dating to c. 2000 BC established that the function of the southeastern subterranean channel connected to the temple pool was to supply the pool with water and not to divert water away from the pool. North and west of the temple the oval terrace wall of its third phase was located. In the centre of the Northeast Temple the remains of a shaft-stairway leading down to a well-chamber was uncovered and shown to be furnished with two subterranean channels leading water into the chamber. South of the Northeast Temple a house with late pottery was excavated. Two stamp seals and two seal-impressed tokens were found.     

How Christianity Won the World

ABSTRACT

This article traces the ideology that allowed Christian civilization to conquer the world. It opens with a view of biblical “national” foundation myths, the Exodus and the Babylonian Exile, and shows how this ideology also allowed for ethnic cleansing, if not genocide, and how those played a dominant role in the mind of western Christians who simply adopted the biblical attitude to foreign nations as their own. A changing perspective including a not so historically dominated reading of the Bible may put an end to the western idea of a God given right to oppress all the nations of the world.
