Lightning and free neutrons

At http://chiefio.wordpress.com/2012/03/27/cue-oliver-m-lightning-makes-fre... ... after a quarter of a century of denying Russian research, scientists in the West have at last acknowledged lightning can cause free neutrons. As they have been in denial for so long it is no surprise they are saying these are soft neutrons - not the big strong neutrons that will cause them sleepless nights. However, they have opened the drawbridge, EM Smith counters, and a lot of new ideas will flourish.

Windy Energy

At www.physorg.com/print248597825.html ... we learn that a paper in Nature claims the extraordinarily high energy emissions at the heart of the Crab Nebula come not from a pulsar at its core but from wind. The pulsar is what is left from after a large supernovae event, theorised as being a neutron star that spins 30 times a second - and appears to pulse in the process. Until now scientists have assumed the energy comes from the pulsar - as it arrives in bursts.

Solar Cycle

At  http://en.wikipedi.org/w/index.php?title=Solar_cycle&oIdid=476364656 the Wikipedia entry on the solar cycle is interesting - it looks at the history of the subject and notes that as long ago as 1908 sunspots were shown to  be strongly magnetised, and a bit later, the magnetic polarity of sunspot pairs was recogised - and the 22/11 years sunspot cycle. Now, as science doesn't proceed as agreeably as it is suggested at Wikipedia we can imagine there was some scepticism of this new finding.

Magnetic Stripes on the Sea Floor

One suspects that many things have been factored into the uniformitarian scientific model not because they are inherently more likely than alternative ideas that are discarded but merely because they fit the pattern of the uniformitarian hypothesis. One of these is the discovery in the early 1960s of magnetic stripes on the sea floor, firstly in deep Atlantic waters, and then in other ocean basins such as the Pacific. In one of those Eureka moments several strands of science came together and locked in Plate Tectonics with the Milankovitch cycle of eccentricity.

Lumps of ice falling out of the sky - what is their origin?

Former SIS member and long time deceased, Eric Crew, in a paper published in Speculations in Science and Technology volume 5:1 (1982) page 67-75 (is this journal still in existence?) with the title, 'Localised violent air disturbances apparently caused by lightning' in which he describes lightning as an atmospheric electrical discharge in which the voltage gradient responsible for the discharge exerts forces on the electrons and positive ions tending to cause movements in opposite directions along the discharge channel.

Electricity and human arteries

See www.physorg.com/print247133863.html ... scientists have found that arteries react curiously to external electric fields, according to a new paper in the forthcoming Physical Review Letters. Meanwhile, at www.thunderbolts.info/wp/2012/01/27/space-magnets/ we learn that in the 1930s Hans Alfven proposed the Milky Way contained a huge magnetic field so that incoming cosmic rays could move in spiral orbits along the arms of the galaxy.

Cold Plasma

'Low energy ions: a previously hidden solar system particle population' is the title of a paper in Geophysical Research Letters - see www.physorg.com/print246632486.html. Cold plasma in the upper atmosphere are low energy ions that couldn't be seen, or could not be detected, until recently. These electrically charged, and yes, they did mention the word electric, affect how the earth's system interacts with the Sun - and there is an abundance of cold plasma up there.

Watch the face of the Sun ...

You can now pick up a video or image of theSun on a weekly basis, just to see what it has been doing in the previous 7 days - www.physorg.com/print244977331.html. The Solar and Heliospheric Observatory (SOHO) is a co-operative venture between NASA and the European Space Agency (EPA) designed to study the internal structure of the Sun, its outer atmosphere and the origin of the solar wind, and the stream of ionised gas, or plasma, that blows outward throughout the Solar System.
