Holocene Warmth

At www.sciencedaily.com/releases/2019/04/190411101735.htm ... driving a wedge into historic gaps in climate science. In this instance, Hokkaidu University in Japan has found the Beaufort Sea, on the margin of the Arctic Ocean, was not completely frozen over during the late Ice Age (the warm period prior to the Younger Dryas event). They used ice wedges from the Alaskan permafrost as evidence.

Texas a tropical savannah

At www.sciencedaily.com/releases/2019/04/190411101824.htm ... ancient Texas was a Serengeti savannah with animals such as elephant, rhinoceros and alligators etc. During the 1930s unemployed Texans were recruited to dig around at a couple of sites that were fossil rich - by the University of Texas in Austin. Tens of thousands of specimens were retrieved and have been briefly studied on a number of occasions, over the last 80 years or so. They have tended to concentrate on the big animals, but now, a new research team has studied them as a whole, small animals as well as the big ones.

That Black Hole Image

William has sent in a link to Thunderbolts - on the black hole image. Thunderbolts reply and claim the ring of lighyt with a dark centre, somewhat like a liquorice allsort, is in fact a plasmoid - not a black hole. Go to www,thunderbolts,info/wp/2019/04/black-hole/ ... which is one way of approaching the so called event horizon - a plasmoid captured ramping up charged particles, electrons spirally into the electromagnetic field giving off X-rays and radio emissions. It also makes sense for the galaxy to have the equivalent of the solar wind - but in a supermassive form.

Fast Moving Genetics

Paul Reich has only just had his paperback version of up to the minute genetics published and he is already out of date it would seem - within a couple of months. At https://archaeologynewsnetwork.blogspot.co.uk/2019/04/multiple-denisovan... ... the Denisovans, contemporaries of the late Neanderthals, were discovered in a cave deposit in southern Siberia, but they appear to be a much more extensive branch of humanity than imagined up to now.

Jupiter and the Solar Wind

At www.jpl.nasa.gov/news/news.php?feature=7369 (April 2019) ... new observations indicate auroras on Jupiter are heating the planet's atmosphere - and that it is a rapid response to the solar wind buffeting the poles. This has big implications we might have thought as global warming on Earth may be facilitated by the same process - but not so (it is said with a straight face).

Do You Understand Fracking

Not sure if this is worth posting as it amounts to some angst. I don't for one moment think most people take diagrams of fracking literally. They are like London Underground maps. They don't follow the route as in real life, bends and changes in direction, but are schematically composed for a paper map. Same goes for fracking diagrams where the pipe and drill are said to turn sharply from vertical to horizontal when just by thinking about it one would realise the turn was much more gradual.

Black Hole Image

At https://astronomynow.com/2019/04/10/virtual-telescope-captures-first-dir... ... we are told that after years of observation and data analysis an international team of astronomers have capture images of a massive black hole - see below. Actually, it is the event horizon that can be seen, marking the boundary between normal space and the unknowable interior (of the black hole). The encircling ring of light is made up of photons from accelerated particles of gas and dust being pulled towards and around the event horizon. The image closely matches theory.

Bugs in the Air

At www.eurekalert.org/pub_releases/2019-03/ru-bmt032019.php ... bacteria may travel thousands of miles through the air, globally. Press release from Rutgers University on a study published in the Philosophical Transactions of the Royal Society B - which shows that rather than bacteria hitching a ride on people and animals they are able to travel through the air (includes viruses). In this instance they are talking about bacteria with anti-biotic resistant genes.

Cassini Latest

At www.jpl.nasa.gov/news/news/php ... a few days ago (see also www.sciencedaily.com/releases/2019/03/190328170639.htm ... and https://solarsystem.nasa.gov/cassini ...). NASAs Cassini mission has found Saturn's rings coat tiny moons - or rather, five small moons nestled in and near the rings, with material. The surface of these moons are covered with material originating from the rings.

Bone Bed Dakota

The K/T boundary vent is back in the news - see www.sciencedaily.com/releases/2019/03/190329144223.htm ... in the aptly named Hell Creek formation in North Dakota we have a bone bed laid down by a giant wave - or waves. There is a certain amount of scepticism abroad amongst other geologists and paleontologists - but is that sour grapes. Or is it all just too neat.
