The Tasmanian devil (Sarcophilus harrisii) was widespread in Australia during the Late Pleistocene but is now endemic to the island of Tasmania. Low genetic diversity combined with the spread of devil facial tumour disease have raised concerns for the species' long-term survival. Here, we investigate the origin of low genetic diversity by inferring the species' demographic history using tempora...

The article analyses the vision of devil in selected tales Vie des peres, a collection pious from thirteenth century, freely inspired by patristic literature and medieval exempla. period which was written, bridges gap between early late Middle Ages: it is time when perception changing, he becoming increasingly feared. analysis focuses mainly on four stories at centre story, his very image sourc...

with the actions of evil-spirits, and the symptoms of both low and violent deliriums are considered by the villagers to be the plays of devils only. Various methods of treatment ave in vogue, and at times, resorted to, when a man has the ill-luck to be possessed by a devil. If a man gets seriously ill, just after fishing at night, he is supposed to be possessed by a water devil, which goes by t...

Avoidance behaviour can play an important role in structuring ecosystems but can be difficult to uncover and quantify. Remote cameras have great but as yet unrealized potential to uncover patterns arising from predatory, competitive or other interactions that structure animal communities by detecting species that are active at the same sites and recording their behaviours and times of activity....

BACKGROUND Devil Facial Tumour Disease (DFTD) is a unique clonal cancer that threatens the world's largest carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii) with extinction. This transmissible cancer is passed between individual devils by cell implantation during social interactions. The tumour arose in a Schwann cell of a single devil over 15 years ago and since then has expand...

turn of the last century. Although in both previous cases devil numbers rapidly recovered, this is the first population crash since the introduction of foxes to Tasmania, and the concern is that the foxes will occupy the devil's niche and make a recovery much harder. This, of course, has serious implications for other native species. Tasmanian devils are mainly scavengers and they clean up the ...

Immune checkpoint molecules function as a system of checks and balances that enhance or inhibit immune responses to infectious agents, foreign tissues, and cancerous cells. Immunotherapies that target immune checkpoint molecules, particularly the inhibitory molecules programmed cell death 1 and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), have revolutionized human oncology in recent ye...

Satan has captured the imagination of writers in the English language for centuries. This figure and the notion of evil have gone through many changes in English literature of the 19 and 20 centuries. Something changed Satan during this time, and made him into an arbiter of truth rather than a figure of rebellion. In The Mysterious Stranger, Mark Twain used him as the grand narrator of the univ...
