The association between darkness and depression is well established. Now a March 25 study in the Proceedings of the National Academy of Sciences reveals for the first time the profound changes that light deprivation causes in the brain.
Neuroscientists at the University of Pennsylvania kept rats in the dark for six weeks. The animals not only exhibited depressive behavior but also suffered damage in brain regions known to be underactive in humans during depression. The researchers observed neurons that produce norepinephrine, dopamine and serotonin—common neurotransmitters involved in emotion, pleasure and cognition—in the process of dying. This neuronal death, which was accompanied in some areas by compromised synaptic connections, may be the mechanism underlying the darkness-related blues of seasonal affective disorder.
Principal investigator Gary Aston-Jones, now at the Medical University of South Carolina, speculates that the dark-induced effects stem from a disruption of the body’s clock. “When the circadian system is not receiving normal light, that in turn might lead to changes in brain systems that regulate mood,” he says.
Treating the rats with an antidepressant significantly ameliorated brain damage and depressive behaviors. “Our study provides a new animal system for antidepressant development. Many existing animal models depend on stress. Our model is a stress-free means of producing a depression. It might be particularly relevant to seasonal affective disorder, but we think that it is relevant to depression overall,” Aston-Jones says.

It is possible to travel faster than light. You just wouldn't travel faster than light.
Seems strange, but by manipulating extra dimensions with astronomical amounts of energy, two Baylor University physicists have outlined how a faster-than-light engine, or warp drive, could be created that would bend but not break the laws of physics.
"We think we can create an effective warp drive, based on general relatively and string theory," said Gerald Cleaver, coauthor of the paper that recently appeared on the preprint server ArXiv.orgIt is possible to travel faster than light. You just wouldn't travel faster than... more

10 powerful requests for today - by Dieter Braun (Indian in the machine)
1. I request to live in pure clean air, and to have pure clean water and
soil to grow pure clean food. Pure clean air, food, water and soil are a birthright to all.
2. I desire to purify myself in a joyful and powerful manner.
3. I request the end of the bush cabal and/or any dark cabal, and the
transmutation of all darkness I experience, into Light.
4. I request the Angels of the Universe, to come even closer to planet Earth.
5. I request that humans reaffirm their need for outside assistance at
this time, from our loving star family.
6. I desire to live on planet Earth, to experience permanent peace on planet Earth.
7. I comprehend that all are equal in the universe, therefore may all
manmade laws reflect this immediately and Now!
8. I desire to live in a world where spiritual awareness is a priority in governance.
9. I call for the end of all planetary slavery!
10. I call forth financial abundance to spread far and wide across the planet like never before!

A lack of sunshine could help explain high levels of obesity, researchers have found.
Studies showed that levels of vitamin D - of which sunlight is the most natural source - tend to be lower in the bodies of overweight people.
Insufficient vitamin D in the blood interferes with the hormone leptin, which signals to the brain when the stomach is full.
The research into vitamin D levels was carried out by Aberdeen University and is published in the scientific journal Bone. Between 1998 and 2000, data was gathered on 3,100 women living in the north east of Scotland.
Estimates were taken of how long they had been exposed to sunlight the previous year and the amount of vitamin D they obtained from food such as eggs and oily fish.
Researchers found that those with an average body mass index (BMI) of 34 - which is above the BMI measure of clinical obesity - produced 10% less vitamin D than those of average weight.
Dr Helen Macdonald, of Aberdeen University's department of medicine and therapeutics, said: "The link between low vitamin D levels and obesity is significant... We think that obese people are not getting enough sunshine, or that what vitamin D they do have is going into fat stores and is not accessible.
"The fact that obese people are prone to low vitamin D levels is a concern in terms of heart disease, the functioning of the immune system and other diseases such as cancer.
"Lifestyle is also a huge factor. Even when there is beautiful sunshine, we are concerned that people are not getting out there and enjoying it."
Dr Macdonald, who led the study, said that comparisons would be made with similar research in Surrey to establish how specific the problem is to Scotland.
Is this something that you've experienced directly? I know loads of women who've lost weight or simply lost interest in when they've been in hot countries with plenty of sunshine for long periods, so it seems very relevant. Could it be that a healthy outdoor lifestyle could do even more good to our bodies than we realised? And if so, shouldn't our bosses be compelled to send us outside right this minute!

Sure, there's always the pukelight for good times around the house, but sometimes you've just got to do some damage -- which is where The Torch from Wicked Lasers comes in. The 4100-lumen flashlight is in the Guiness Book of World Records, and can ignite paper, light cigarettes, melt plastic, and even fry an egg -- but only has a fifteen minute battery life. Check a video of The Torch taking out a pile of plastic bags after the break, and hit the read link for even more high-candlepower destruction.Sure, there's always the pukelight for good times around the house, but sometimes... more
