Electric Lightning Balls

At http://phys.org/print295092645.html ... a report on a paper researching ball lightning, 'Further Insight into the Nature of Ball Lightning' in the Journal of Physics and Chemistry says that ball lightning is a natural plasma like phenomenon associated with thunderstorms. A recently discovered laboratory phenomenon had striking similarities - observed when a high power spark was discharged form a cathode protruding from an electrolyte solution.

The Meteor and St Paul

This is all a bit speculative but interesting nonetheless. At the 76th Annual Meteoritical Society Meeting (2013) the Chelyabinsk (Russian) meteor will be discussed and historical examples of similar will be aired, which of course include the 1908 Tunguska event. It then back tracked to first century AD as someone suggested a particular person, St Paul none the less, experienced a meteor event near Damascus (the flash of light that was interpreted as the Voice of God speaking to Paul at a personal level).

Anapole fields

At http://phys.org/print290089874.html ... most of the matter in the universe may be made out of particles with a doughnut shaped electromagnetic field known as an anapole. This hypothesis endows dark matter with electromagnetism and the research is published in the journal Physics Letters B (see  also adsabs.harvard.edu/abs/2013PhLB..722...341H).

Traditional Cosmology: the Global Mythology of Cosmic Creation and Destruction

Another book, the third in a row. This one is by Rens van der Sliujs, Traditional Cosmology: the Global Mythology of Cosmic Creation and Destruction - see www.mythopedia.info

Electrical activity in the upper atmosphere

NASA has launced a couple of rockets in the Pacific in order to find out more about the ionosphere - known as the EVEX experiment. Look out for more information as the results are analysed. See http://phys.org/print287223658.html (quoting Universe Today).

Photon production in planetary atmospheres

This is a guest post by Tim Cullen at Tall Bloke's Talk Shop - see http://tallbloke.wordpress.com/2013/05/09/tim-cullen-illumination-from-t... ... professors Mark Smith and Horoshi Imanaka have published a paper available on the Geochemical Society web site and Tim Cullen has found it extremely useful as it illustrates photons are produced in the atmosphere. This idea was commonly regarded as cranky, he suggests, and ignored.

Lightning caused by cosmic rays?

On May 8th, BBC2 television's 'Nature's Wildest Events' had a piece on lightning - with the admission scientists did not know what actually caused it to happen. This was a bit of a surprise as the BBC is inclined to endorse and recite the consensus view, on almost anything. At http://phys.org/print287054805.html ... we learn that a paper in the journal Physical Review Letters, by two Russian physicists, A Gurevich and A Karashtin, claim to have found evidence to support the idea lightning is caused by cosmic rays.

Energy from Plasma

Tony Haynes is going to give an update on his research into plasma energy at the next study group meeting - and all members are welcome to attend (see Tony on video on our web site). At http://phys.org/print286441345.html ... fusion power and the attempt to control turbulence in super hot electrically charged gas = plasma (see also http://web.mit.edu/newsoffice and http://pop.aip.org/resource/1/phpaen/v20/i3/p032510_s1
