Fire in the Sun

At www.thunderbolts.info/tpod/2010/arch10/100903fire.htm the Greeks and Romans had a variety of theories on what might power the Sun and surprisingly, the notion they had in the back of their heads was not very different from a plasma filled universe. Even the astronomer, John Herschel, in the 18th century, wrote a letter to Faraday speculating that the Sun might owe its brightness to cosmic electrical currents - with the upper atmosphere of the Sun auroralised by them ...

Dancing Electrons

At www.physorg.com/print202733904.html a report on a paper in the Proceedings of the National Academy of Science that was prompted by physicists who struggled to understand the dance between electrons that create magnetic fields. A new model was formulated to learn more about quantum quirks of high temperature super conductors that has apparently had the side effect on the understanding of ferromagnetism.

Vortex of Fire

At http://wattsupwiththat.com/2010/08/27/tornado-of-fire-in-brazil/ you will find some short video clips of a tornado of fire created during wild fires - transient phenomena captured by the abundance of mobile phones with cameras. Are these combustible tornados?

The video clips are available on a variety of blogs.

Alternative energy

At www.sciencedaily.com/releases/2010/08/100825131445.htm ... devices to capture electricity out of the air are being contemplated - like solar cells capture sunlight. However, it requires more research into lightning - and how it builds up and grows. It is known that water in the atmosphere can accumulate an electric charge and transfer them to other materials it comes into contact with - known as 'humidity-electricity'

Electricity in the brain and electricity in the weather

At http://opa.yale.edu/news/article_print.aspx?id=7646 July 14th 2010, Yale University press release - scientists at Yale have a paper in Neuron which claims electrical fields can influence the activity of brain cells - the little grey cells of Monsieur Poirot perhaps? It is known that transcranial magnetic stimulation and deep brain stimulation are effective in the treatment of neurological disorders.

Shrinking atmosphere

Yes, the atmosphere is shrinking - as a result of low levels of solar radiation - a lack of sun spots. At www.physorg.com/print202054025.html there is a report on a paper in Geophysical Research Letters from research funded by NASA and the National Science Foundation which sponsors the National Centre for Atmospheric Research (NCAR) at Boulder, Colorado. It is now thought the Sun's magnetic cylce may vary much more than previously considered possible.

Magnetic fields of stars - a breakthrough?

At www.physorg.com/print201526370.html ... a University of Dundee press release claims a breakthrough in the study of magnetic fields - which will add to what we know about stars including our Sun. The team, from a magnetohydrodynamics research group, used computer simulation of plasma in the atmosphere of the Sun and by looking at how the magnetic field responded to plasma they have uncovered what they say are now rules that govern, or exact influence, over the solar atmosphere.

Ancient Creation Myths - one kind of interpretation

At www.thunderbolts.info August 20th ... 'What on Earth ... ' is a post by Rens van der Sluijs and along the vein of his auroral notions as outlined in his book and in various articles. He suggests ancient creation myths have an origin in auroral phenomena and take place with the magnetosphere of the earth - which on occasions appeared to be alive. For example, according to the San Bushmen, 'in the earliest days the Sun lived among the tribes of the bush' and 'was like other men' - which is clearly not right.

Life influenced by cosmic rays (?)

At www.dailygalaxy.com August 12th ... palaeontologist Bruce Leiberman suggests we should think about extraterrestrial events leading to higher rates of mutations in organisms and damage to DNA. However, the rate of change is on a uniformitarian scale and relates to the rotation of the solar system within the Milky Way galaxy and periodic encounters it may have with greater rates of radiation and cosmic ray bombardment.

The auroral heartbeat of Saturn

At www.physorg.com/print200123247.html ... a paper in Geophysical Research Letters (Aug 6th) claims that Saturn's aurora, a low ultraviolet glow which illuminates the upper atmosphere near the poles, pulses roughly at one a day (Saturnian time). The study used Hubble Space Telescope images from 2005 to 2009. There is a pulse to radio emissions too and the aurora heartbeat appears to be in tandem with the radio emissions
