At http://cosmictusk.com/interesting-support-for-younger-dryas-boundary-ydb... ... you can read the abstract of an article with the title, 'Late Glacial Fire and Nitrogen dynamics at lacustrine sites in Alabama and Michigan: evidence of an acid rain event?'. Sediments from three lakes show roughly coeval nitrogen perturbation at the onset of the Younger Dryas (with a distinct shift in vegetation alongside evidence of landscape fires).
At www.sciencenews.org/article/mountains-saturn-moon-may-have-come-from-space ... Yes, mountains made out of space debris - on a moon of Saturn (but what is good for the goose might also be good for the gander) - could it have happened on Earth?
At www.dailypost.co.uk/news/north-wales-news/anglesey-mysterious-artefact-d... ... the Neolithic in western Britain, or that part close to the Great Orme copper mines, has come up with evidence of copper artefacts as early as 3500BC. Does this warrant redefining a large tract of what is now the Neolithic (stone using) as Copper Age (even when such objects are rare in an archaeological context)?
At www.sciencenews.org/article/la-brea-tar-pits-yield-exquisite-ice-age-bees ... the image below (at the same link) is of the pupae of a bee (comparing a real life version with the fossilised one). The species still lives in the modern world - but the fossil pupae dates from 35,000 to 40,000 years ago. The presence of bees in the tar pit suggests nearby woodland and river
banks with pollen rich wild flowers or blossom in a fairly cool and moiste climate.
At http://popular-archaeology.com/issue/03012014/article/the-first-great-hu... ... genetic studies, we are told, indicate Palaeolithic people grew in huge numbers between 80,000 and 60,000 years ago. Why this should have happened is not clear - but the idea of growing numbers of people at around that time is very convenient for the Out of Africa theory (and therefore should be treated with a bit of caution).
Most ethanol produced uses high temperature fermentation to chemically convert corn, sugar cane, palm oil or any suitable plant material into liquid fuel. A new technique has been developed at Stanford University and requires no fermentation - and little raw material from the plant world - see http://wattsupwiththat.com/2014/04/09/making-ethanol-without-the-need-to... ... which must be a good thing in the long run. At the moment it is a lab based experiment - will it be efficient in practise?
That is the inference in a story at www.dailygalaxy.com/my_weblog/2014/04/young-galaxies-powered-by-massive-... .... and opens with the statement, all matter of fact, 'quasars- are young galaxies powered by massive black holes, extremely bright, extremely distant, and highly red shifted ...'
No - not a shindig in Wales but a reference to Cambrian fossils at www.livescience.com/44654-first-fossil-blood-vessel-arthropod.html .... where it has been found that creatures living 520 million years ago had a sophisticated heart and blood vessel system similar to lobsters and other creatures in the modern world. The remarkable fossils come from a site in Yunnan Province in China which preserved intact the blood vessel system.
Speak of the devil. I mentioned Neanderthal DNA research two days ago and the very next day spied this story at http://archaeologynewsnetwork.blogspot.co.uk/2014/04/new-method-confirms... ... Technical objections to the idea Neanderthals interbred with the ancestors of EuroAsians have been overcome thanks to a genome analysis method described in the April 2014 issue of the journal Genetics. The research is ongoing and already thee are two camps in the debate.
