Cosmic Magnetic Fields

At www.physorg.com/print223562554.html is a story derived from Universe Today, on cosmic scale magnetic fields

 

 

It notes that astronomers tend to button up when such large magnetic fields are mentioned - and generally ignore their presence. Reason? Lack of an explanation.

Update on Comet Elenin

NASA (see www.jpl.nasa.gov/news/news.cfm?release=2011-135?cid=release_2011-135 ) has issued a news release on Comet Elenin - and its progress from the outer reaches of space on its journey towards the inner solar system. It is now 170 million miles away and so far it has been a bit of a wimp - according to NASA spokesman Don Yeomans. Even at its closest point observers may require the use of binoculars - and a clear sky. However, we have until October 16th for things to change - when it will be 22 million miles away.

New York tsunami event 300BC

Katherine Cagen (Harvard) and Dallas Abbot (Lamont-Doherty Earth Observatory, Columbia University, New York) 'Evidence for a tsunami generated by an impact event in the New York metropolitan area approximately 2300 years ago' (2009) can be downloaded as a pdf file from http://cosmictusk.com and consists of roughly 20 pages, mainly of pictures of sampling from sediments. The abstract, one page, says that it is proposed an oceanic impact event caused a tsunami wave to rip through what is now New York, around 300BC.

Looking for Sodom

This is the title of an article at http://popular-archaeology.com/issue-printer/april-2011 .... looking for the Biblical cities of Sodom and Gomorrah, the cities of the Plain that were destroyed by God, have proved to be a little elusive. It seems that excavations in progress at the moment may be a little promising - but don't hold your breath. Previously, archaeologists have focussed on the region to the SE of the Dead Sea where a narrow alluvial plain is situated. Not exactly the kind of Plain envisaged in the Biblical text, too small perhaps.

Movements of the earth at the point of axis

The New York Times (see www.nytimes.com/2011/04/26/science/26qna.html?_r=1=science 'As the World Turns' asks, do shifts of the earth's axis produced by earthquakes alter world weather? - presumably a question an earnest AGW enthusiast might be concerned about - why is snow still falling in parts of the US and Canada? Its supposed to be spring. Its very warm over here in NW Europe but other parts of the northern hemisphere are not so lucky.

Chinese Homo erectus and the Secrets of Pavilland Cave

At www.unreportedheritagenews.com/2011/04/did-peking-man-wield-spear-new-re... there is a posting on Peking Man, dated by a new methodology some 700,000 years ago and known from the cave system at Choukoutien in China (mentioned by Velikovsky). Related to Homo erectus, Peking Man appears to have adapted to cold Ice Age conditions, but these things are open to interpretation.

Carbon - a pollutant or an essential of life?

Over at http://wattsupwiththat.com on April 29th we learn that some AGW doomsayers have said the devastating Alabama tornadoes are a result of 'C02 pollution' rather than other factors - but incredibly, at www.joannenova.com.au/carbon-demonised-by-climate-propaganda/ it seems that some people really do think volcanoes, earthquakes and tsunamis are induced by global warming and rising levels of C02. Worse still, some people are so convinced carbon is a pollutant they think they should try and avoid it altogether - even in food.

Problems with ancient DNA

Recent DNA tests on the mummies of Tutankhamon and his close relatives came up with the odd, if not  too likely finding that they had origins in western Europe. Now it is thought the DNA sampling procedure was open to contamination. The mummies have been handled by a lot of European archaeologists and scientists - so that is not surprising. See www.nature.com/news/2011/110427/full/472404a.html for an idea of the limitations of DNA research and the inhouse controversies about the way it is applied in practise - and an expectation it might get better in the future.

And Electric Brains ...

At www.sciencedaily.com/releases/2011/04/110428143155.htm ... biologists have found that electrical oscillations in the brain are more important than they imagined as they play a role in organising cognitive functions such as memory and are particularly important as they allow the brain to store information that in turn allows us to navigate around the physical environment - a sort of inbuilt GPS system inside our heads. The paper describing it all can be found in Science of April 29th (2011).
