Spectacular Northern Lights linked to suicidal depression

Alaska's tragically high number of suicide may be related to cosmic storms and the Northern Lights (aurora borealis), according to an expert in the study of brainwaves.

Depression in the Far North has in general been attributed to the deep, dark and long winters. But Dr Anita Bush,________specialises inelectroencephalography, has complicated matters by discovering a link between solar flames and brainwave activity in two sets of Alaskans she has studied for the past five years.

The microscopic electric impulses were concentrated in an area of the brain known also to cause seasonal affective depression (SAD), the condition up to now blamed for dozens of suicides each year in the remote Alaskan coast. Suicide levels among the state's 15 to 24-year-olds have risen sharply in recent years, to six times the national average, says Dr Bush.

She has not yet demonstrated a link between increased brainwaves and suicidal tendencies but she thinks existing data on supposed SAD cases may in fact include cases of suicide induced by geomagnetism. For now she has suggested that special dark glasses, worn against solar flames and the Northern Lights, ________elevate morale among the suicidal.

Some of her sceptical colleagues as Professor Tom Hallinan, one of a team studying the aurora, recently insisted that the most serious health risk in watching the Alaskan night sky was a cricked neck.
