My Way News - Martian soil may contain detrimental substance

My Way News - Martian soil may contain detrimental substance

NASA's Phoenix spacecraft has detected the presence of a chemically reactive salt in the Martian soil, a finding that if confirmed could make it less friendly to potential life than once believed.

Scientists previously reported that the soil near Mars' north pole was similar to backyard gardens on Earth where plants such as asparagus, green beans and turnips could grow. But preliminary results from a second lab test found perchlorate, a highly oxidizing salt, that would create a harsh environment.

The first test "suggested Earth-like soil. Further analysis has revealed un-Earthlike aspects of the soil chemistry," chief scientist Peter Smith of the University of Arizona in Tucson said in a statement Monday.

On Earth, perchlorate is a natural and manmade contaminant sometimes found in soil and groundwater. It is the main ingredient in solid rocket fuel and can be found in fireworks, pyrotechnics and other explosives.

It's unclear how perchlorate forms on Mars or how much there is of it. NASA is investigating whether the substance could have gotten there by contamination before launch. Phoenix used another fuel, hydrazine, to power its thrusters and land on the red planet on May 25.

[...]

Scientists want to confirm their results because another Phoenix instrument that bakes and sniffs soil samples found no evidence of perchlorate during a run on Sunday.

Brown University geologist John Mustard, who has no role in the mission, said judgment about the soil's potential to support life should be reserved until all the data are in.

But at first glance, "it is a reactive compound. It's not usually considered an ingredient for life," Mustard said.

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking ...

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the...

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
