Conquistador your stallion stands in need of company And like some angel's haloed brow You reek of purity I see your armor plated breast Has long since lost its sheen And in your death mask face There are no signs which can be seen And though I hoped for something to find I could see no maze to unwind

A dollop of peanut butter and a ruler can be used to confirm a diagnosis of early stage Alzheimer's disease, University of Florida Health researchers found.
Jennifer Stamps, a graduate student in the University of Florida (UF) McKnight Brain Institute Center for Smell and Taste, and her colleagues reported the findings of a small pilot study in the Journal of the Neurological Sciences in October 2013.
Stamps came up with the idea of using peanut butter to test for smell sensitivity while she was working with Dr. Kenneth Heilman, one of the world's best known behavioral neurologists, from the UF College of Medicine's department of neurology.
While shadowing doctors in Heilman's clinic, she noticed that patients were not tested for their sense of smell. The ability to smell is associated with the first cranial nerve and is often one of the first things to be affected in cognitive decline.
"Dr. Heilman said, 'If you can come up with something quick and inexpensive, we can do it,'" Stamps says.
She thought of peanut butter because, she said, it is a "pure odorant" that is only detected by the olfactory nerve and is easy to access.
According to the Alzheimer's Association, Alzheimer's disease affects 5.2 million people in the US and will cost the nation $203 billion in this year alone.
Peanut butter on teaspoon
Researchers found that by placing a dollop of peanut butter on a ruler, they could identify early stages of Alzheimer's disease, based on patients' ability to detect the odor at certain distances.
The Association estimates that one American develops Alzheimer's every 68 seconds, and they expect to see this figure rise to one American every 33 seconds by 2050.
In the study, patients who were coming to the clinic for testing also sat down with a clinician, who was armed with 14 grams of peanut butter - which equals about 1 tablespoon - and a metric ruler. The patient closed his or her eyes and mouth and blocked one nostril.
The clinician opened the peanut butter container and held the ruler next to the open nostril while the patient breathed normally. By moving the peanut butter up the ruler 1 cm at a time during the patient's exhalation, they were able to measure the distance at which the patient could detect the odor.
The distance was recorded and the procedure repeated on the other nostril after a 90-second delay.
The clinicians running the test did not know the patients' diagnoses, which were not usually confirmed until weeks after the initial clinical testing.
Sense of smell loss
The scientists found that patients in the early stages of Alzheimer's disease had a dramatic difference in detecting odor between the left and right nostril - the left nostril was impaired and did not detect the smell until it was an average of 10 cm closer to the nose than the right nostril had made the detection in patients with Alzheimer's disease.
This was not the case in patients with other kinds of dementia; instead, these patients had either no differences in odor detection between nostrils or the right nostril was worse at detecting odor than the left one.
Of the 24 patients tested who had mild cognitive impairment, which sometimes signals Alzheimer's disease and sometimes turns out to be something else, about 10 patients showed a left nostril impairment and 14 patients did not.
The researchers said more studies must be conducted to fully understand the implications.
"At the moment, we can use this test to confirm diagnosis. But we plan to study patients with mild cognitive impairment to see if this test might be used to predict which patients are going to get Alzheimer's disease."
Stamps and Dr. Heilman point out that this test could be used by clinics that do not have access to the personnel or equipment to run other, more elaborate tests required for a specific diagnosis, which can lead to targeted treatment.
At UF Health, the peanut butter test will be one more tool to add to a full suite of clinical tests for neurological function in patients with memory disorders.
Non-invasive, early stage test
One of the first places in the brain to degenerate in people with Alzheimer's disease is the front part of the temporal lobe that evolved from the smell system, and this portion of the brain is involved in forming new memories.
"We see people with all kinds of memory disorders," Heilman said. Many tests to confirm a diagnosis of Alzheimer's disease or other dementias can be time-consuming, costly or invasive. "This can become an important part of the evaluation process."
The UF study could help by detecting a person's likelihood of developing the disease at a much earlier stage, with a non-invasive test.
The Alzheimer's Association acknowledge that at the moment, there is no cure for the disease, nor can current Alzheimer's treatments stop Alzheimer's from progressing. They can, however, temporarily slow the worsening of dementia symptoms. This improves the quality of life for both sufferers and their caregivers.
"No single raindrop ever feels like it is responsible for the flood."
When widely adopted, bicycles can have a big effect on a population.
While Europe is getting fatter, the Netherlands is getting thinner. It’s the only country in which the World Health Organization (WHO) is predicting a decline in obesity rates.
Speaking of raindrops, one of my favorite movies of all time is Butch Cassidy and The Sundance Kid. The bicycle scene with Butch and Etta is unforgettable. Like many, I grew up riding a bike. I learned at a young age how to fix a flat and put on the chain. I loved the freedom of riding around town. My first stitches, five in the chin, were earned in a bike wreck that was caused by me. Consequences are such a powerful thing.
Sadly, kids these days tend to text their friends, or chat virtually inside an x-box game, rather than ride over to each other's home.
The bicycle is an amazing piece of technology that is capable of solving at least a few of our modern day health, financial, and energy problems. Consider that in many parts of the world where bicycles are the norm there is usually far less obesity, debt, and reliance on imported oil and the offensive war machine that is required to invade nations and murder people so that we may take their oil.

California missile test sparks frenzy as residents suspect 'UFO' sighting
By AFP Published: November 8, 2015
A missile test off the California coast sparked frenzy on social media and spooked residents Saturday who believed they had just seen a UFO.
The Twitter hashtags #Navy, #comet and #UFO were trending as social media users uploaded videos and pictures of the mysterious bright light illuminating the night skies.
“There’s a UFO in Los Angeles. I’m so excited. I’m so ready,” tweeted Shane Dawson, well known for his YouTube videos.
“Los Angeles UFO? It was not a comet. My son saw the Unidentified Flying Object in Hollywood,” tweeted @AnnieJacobsen.
The San Diego Union-Tribune said that the streaking light was visible as far away as Nevada and Arizona and authorities were reportedly flooded with calls.
But just when some were predicting the end of the world, officials moved to clear up the mystery.
“Navy Strategic Systems Programs conducted scheduled Trident II (D5) missile test flight at sea from USS Kentucky, an Ohio Class SSBN, in the Pacific Test Range off the coast of Southern California,” Navy Cmdr Ryan Perry said in a statement to US media.
“The tests were part of a scheduled, on-going system evaluation test.”
