Electromagnetism news

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

Lightning and Hurricanes

At www.physorg.com/print200126122.html (see also www.jpl.nasa.gov/news/ ) is about a connection between lightning (electricity in the atmosphere) and hurricane intensification. NASA are now peering inside storms in search of the lightning and how it interacts with the surface of the earth - particularly how it might affect hurricane development and intensification, as well as other phenomena of nature.

EU Presentation.

The Thunderbolts newsletter has announced (August 4th) that Dave Smith, editor of the 'Thunderblog' at www.thunderbolts.info will make a prresentation of the Electric Universe hypothesis (see http://live.worldsci.org ) this saturday coming.

Geoglyphs from the Atacama Desert in Chile

At http://archaeology.about.com/od/artandarchitecture/a/atacama_glyph.htm there is a post on geoglyphs from the Atacama Desert in Chile, and how they were made. Geometric shapes are common, such as circles, concentric circles, circles with dots, rectangles, crosses, arrows, parallel lines, rhomboids, all of the symbols are also common in pre Hispanic ceramics and textile design.

Magnethydrodynamics

Magnethydrodynamics is the subject of a web site at http://mysite.du.edu/~jcalvert/phys/mhd.htm which it is claimed is 'closely related' to plasma dynamics. It involves the dynamics of matter moving in an electromagnetic field, especially where currents established in the matter by induction  modify the field. It involves conducting fluids, liquid and gas, but differs from plasma dynamics.
