Oysters, MWP and the Romans

At http://wattsupwiththat.com April 20th ... we have a report from 'C02 Science' of a paper on temperature reconstruction from plankton shells in a sea bed core off Sulawesi in Indonesia - and the Medieval Warm Period (MWP) is clearly distinguishable, as well as the Little Ice Age (drop in global temperatures). For years, climate scientists in Europe and North America have been insisting the MWP and LIA were regional and local phenomenons of not much consequence. This new paper suggests it was global.

The Origin of Water on Earth

At http://wattsupwiththat.com April 18th ... we have a post by Steven Goddard, 'Volcanoes and Water' ... with a series of stunning images. Water vapour is consistently the most abundant of volcanic gases - normally comprising some 60 per cent of total emissions. C02 accounts for between 10 to 40 per cent. Around 70 per cent of the surface of the earth is covered with water - but where did all that water come from?

Intelligent Design and Human Behaviour

At www.sciencedaily.com/releases/2010/04/100413170731.htm ... although evolutionists and creationists strongly differ over the role of intelligent design in the origin of species they do appear to agree about the role it plays in the origin of human inventiveness. In the May issue of American Scientist there is an article on this issue.

Electrified Lunar Craters

Science Daily April 17th (www.sciencedaily.com/releases/2010/04/100416185151.htm ) ... as the solar wind flows over natural obstructions on the moon it may charge polar lunar craters to 100s of volts according to new NASA calculations. Polar lunar craters are an object of interest as a possible source of water for astronauts and have therefore attracted interest. The moon's orientation towards the sun keeps polar craters in permanent shade - allowing temperatures to plunge to -400 degrees Fahrenheit.

Black Holes

Daily Galaxy April 16th (www.dailygalaxy.com) ... does our universe exist in a black hole? Cosmic string theorists, it is alleged, have suggested the whole universe may exist in a black hole. In their view the pre-Big Bang universe is vast, infinite, and stretches indefinitely backwards in time. They think the universe might be destroyed on a regular basis - it's space time twisted into black holes.

Dating anomalies

Science News (www.sciencenews.org/view/generic/id58346 ) April 16th ... new age estimates for Homo erectus fossils from Java have produced puzzling results. Anthrolopologists thought Homo erectus had survived on Java until 30,000 years ago - but the new dating method indicates they died out much earlier. The difference is due to the application of differing dating methodologies.

Zodiacal Glow

At www.physorg.com/print190569543.html ... Nesvorny and Jennisken in The Astrophysical Journal attribute the glow that straddles the night time zodiac in the eastern sky as sunlight scattered on dust particles - from  comets. More than 85 per cent of the dust, they say, originated from short period comets - not asteroids. In addition, snow in Antarctica is laced with micro-meteorites and 80 to 90 per cent of this comes from the same source.

Indus Script

www.hindu.com April 16th ... an interview with Professor Asko Parpola, an Indologist from the University of Helsinki, is the subject of this article. He has done sustained work on the Indus script and although it is yet to be decyphered he thinks it is written in a Dravidian language that may be fairly close to Old Tamil. Problems in  decypherment are in part due to the fact that only short and terse pieces of the script have survived.

Dark Matter Doubts

At www.physorg>com/print190631146 ... astrophysicists are looking everywhere for dark matter - inside the Large Hadron Collider, in deep mines, and way out in space, but evidence of dark matter cannot yet be found. It is claimed it makes up a quarter of the energy density of the universe. Current models and simulations cannot acount for the excess in positrons being observed - on the satellite experiment of PAMELA for instance.

Black Holes, Sprites, Solar Flares and Interstellar Water

At www.physorg.com/print190485260.html ... research has found natural particle accelerators can be formed by lightning storms. When intense lightning discharges in thunderstorms coincide with high energy particles (cosmic rays) coming in from space nature forms a giant particle accelerator above the clouds - stripping electrons from air molecules. He is referring to lightning discharges above thunderstorms - known as sprites (see below).
