Pythagorem Theorem

At http://archaeologynewsnetwork.blogspot.co.uk/2016/04/a-3800-year-journey... ... we have a clay tablet from Babylonia that was originally pulled from an excavation of Old Babylonian (Middle Bronze Age) archaeology in what is now Iraq. It concerns school work - and the knowledge of mathematics in the second millennium BC.

Chauvet Pont D'arc

At http://phys.org/print379669279.html ... and http://archaeologynewsnetwork.blogspot.co.uk/2016/04/chauvet-pont-darc-c... ... we have a story about dating the cave art, a head scratching affair. The cave is situated in southern France and is a World Heritage Site. It's walls are decorated with hand prints and drawing of 14 different species of animal - and charcoal from the embers of camp fires in the cave were used to draw some of them. These include bears, horses, woolly rhinoceros, and various big cats.

Green Money Tree

At http://phys.org/print379302444.html ... we learn the World Bank intends to increase funding for renewable energy projects - in developing countries. Should people over there start getting worried?

melting or not melting

  On the day the BBC has an old story about Greenland ice melting (the research was done months ago and is down to the 2015 El Nino) we have news elsewhere that global sea ice is rebounding back - and the Arctic is not melting anymore. See www.vencoreweather.com/blog/2016/04/11/215-pm-global-sea-ice-makes-a-str... ... and we may wonder why the headline news at the BBC is running a story now well out of date (and not mentioning the current findings).

Different interpretations

I was struck by how different people interpret the same image after reading the latest offering from www.thunderbolts.info/wp/2016/04/04/divine-colors/ ... Michael Armstrong sees the gods of old as planetary in origin. Others might see them differently. When it comes to colours such as blue and black he thinks in terms of Saturn expelling dust as dark as soot. He then informs his readers that Kala was one of the names applied to Saturn - a planet. Rather than black Kala was actually dark blue in hue, he tells us. The same colour was associated with Shiva.

What a Whopper

   At www.spaceweather.com - April 11th ... The solar minimum is looking less likely with the emergence of a big sun spot, doubling in size over the weekend.

Tree rings and C14

At https://malagabay.wordpress.com/2016/04/08/irish-guide-to-the-first-mill... ... purports to show that C14 dates prior to 600AD are unreliable as a result of a cosmci event. The detail is missing and one is referred to various earlier posts on revising AD chronology he has made. It would be extremely interesting if C4 diverged from the tree ring graph - even if it was not to the extent he envisages. Somebody else might like to explore the issue.

Life in Space

At http://phys.org/print379308179.html ... an interesting discovery. Ribose and related sugar molecules, the backbone of RNA, or ribonucleic acids, which are important in the coding of genetic information from before the emergence of DNA, is found in comets and asteroids. It may actually be abundant in the universe at large. As such, life beyond the confines of the Earth must be feasible.

Restless Comet

At http://phys.org/print379344355.html ... ESAs Rosetta spacecraft beamed back data from the atmosphere, or coma of Comet Churyumov-Gerasimenko with evidence of a crystalline form of ice known as clathrates - see the April issue of Science Advances  journal. The mystery is that if the comet is composed of building blocks of crystalline ices and clathrates the comet must have conglomerated near the Sun - in the proto solar nebula. Water clathrates contain gas molecules - volatiles locked inside.

Dingo

Staying with Australia, at http://archaeologynewsnetwork.blogspot.co.uk/2016/04/dna-study-suggests-... ... which is another effort to understand the origin of the dingo, a dog that some people see as bearing similarities with Indian village dogs, and others trace only to south east Asia. Its appearance in Australia is dated to around 5000 years ago - and assumes new migrants arrived at that time (but from where).
