Organic Ejecta –Clues to Violent Events in the History of the Universe

Exploding stars, random impacts involving comets and meteorites, and even near misses between two bodies can create regions of great heat and high pressure. Researchers from Imperial College London have now developed a method for analysing the pressure experienced by tiny samples of organic material that may have been ejected from dying stars before making a long journey through the cosmos. The researchers have investigated a type of aromatic hydrocarbon called dimethylnaphthalene, which should enable them to identify violent events in the history of the universe.

The team also believe that their new technique could be applied on Mars, potentially using the existing technology on-board roving laboratories such as the one on the Mars Science Laboratory Mission to glean information about sources of organic matter on the red planet. Recognising the pressures recorded in the aromatic hydrocarbons can help to reveal whether it came from processes generated from ancient living organisms.Samples of dimethylnaphthalene are found in meteorites. Previously, scientists have only had the ability to investigate how they have been affected by heat. The Imperial researchers say their method for detecting periods when dimethylnaphthalenes have experienced high pressure will now allow for a much more comprehensive analysis of organic materials.

In conjunction with the upcoming release of his new book, A Government of Wolves: The Emerging American Police State, John W. Whitehead sits down to discuss several “pressure points” that are threatening the Bill of Rights and undermining our essential freedoms. In part one of this special series, Whitehead examines the increased presence of militarized police.

Invasion of the Body Searchers: The Loss of Bodily Integrity in an Emerging Police State [SHORT]

By John W. Whitehead
January 14, 2013

If you want a recipe for disaster, take police officers hyped up on their own authority and the power of the badge, throw in a few court rulings suggesting that security takes precedence over individual rights, set it against a backdrop of endless wars and militarized law enforcement, and then add to the mix a populace distracted by entertainment, out of touch with the workings of their government, and more inclined to let a few sorry souls suffer injustice than to challenge the status quo.

The resulting concoction, I can promise you, will be a messy, noxious stew unfit for consumption, miserable to digest and with after-effects that will leave you reeling and clutching your stomach in dismay. Such is the nature of life in the emerging police state that is America today, where roadside police stops have devolved into government-sanctioned exercises in humiliation and degradation with a complete disregard for privacy and human dignity.

Consider, for example, what happened to 38-year-old Angel Dobbs and her 24-year-old niece, Ashley, who were pulled over by a Texas state trooper on July 13, 2012, allegedly for flicking cigarette butts out of the car window. First, the trooper berated the women for littering on the highway. Then, insisting that he smelled marijuana, he proceeded to interrogate them and search the car. Despite the fact that both women denied smoking or possessing any marijuana, the police officer then called in a female trooper, who carried out a roadside cavity search, sticking her fingers into the older woman’s anus and vagina, then performing the same procedure on the younger woman, wearing the same pair of gloves. No marijuana was found.

Leila Tarantino was allegedly subjected to two roadside strip searches in plain view of passing traffic during a routine traffic stop, while her two children—ages 1 and 4—waited inside her car. During the second strip search, presumably in an effort to ferret out drugs, a female officer “forcibly removed” a tampon from Tarantino’s body. No contraband or anything illegal was found.

Meanwhile, four Milwaukee police officers have been charged with carrying out rectal searches of suspects on the street and in police district stations over the course of several years. One of the officers is accused of conducting searches of men’s anal and scrotal areas, often inserting his fingers into their rectums and leaving some of his victims with bleeding rectums. Half-way across the country, the city of Oakland, California, has agreed to pay $4.6 million to 39 men who had their pants pulled down by police on city streets between 2002 and 2009.

And then there’s the increasingly popular practice of doing blood draws at DUI checkpoints, where drivers who refuse a breathalyzer test find themselves subjected to forcible blood extractions to test for alcohol levels. Police in Tangipahoa Parish, Louisiana, actually had a registered nurse and an assistant district attorney on hand “to help streamline the ‘blood draw’ warrants and collect blood samples from suspected impaired drivers” at one exercise in holiday drunk driving enforcement. A similar case, Missouri v. McNeely, which deals with a driver who failed a sobriety test, then refused a breathalyzer test and was subjected to a warrantless blood draw, is currently before the U.S. Supreme Court.

I know we have a lot of seasoned canners in the Pack. This article is aimed at the few who are afraid to jump in or are just starting out. Home canning is such a wonderful way to store food for later. Anyone can do it – you just need to learn to do it safely.

We grow and can food for many reasons; to keep our abundant harvest, to save money, to ensure healthy food for our families by avoiding additives or chemicals in packaging, and many more reasons. As we think about canning as a means to preserve food, a reminder about safe canning and storing of food is never out-of-order.

How does canning preserve food?

Home canning, when done correctly, preserves food by removing oxygen, killing bacteria and microorganisms and preventing the growth of yeasts and molds. It is one of the best methods to keep your harvest.

Following safe canning methods and recipes is the only way to lessen the incidences of food poisoning. One of the most dangerous forms of food poisoning is caused by Clostridium botulinum. These bacteria can exist dormant in the soil for many years, and when the conditions are right can multiply rapidly and produce a deadly toxin.

It likes to grow in moist, low acid foods with low levels of oxygen. Improperly handled and processed food jars are the perfect environment for botulinum spores to grow. Washing food before canning can reduce, but not eliminate the spores on the surface of food.

Since botulinum spores can survive boiling water, pressure canning, where tempratures reache at least 240 degrees F and pressures reach 10 to 15 pounds per square inch, needs to be used when canning low some foods. There is no safe method for water bath canning meat and vegetables. Grandma may have done it, but we know now that you must use a pressure canner for low acid foods.

A few simple guidelines to remember are:

1. Make sure you are using up-to-date methods and recipes

The decision to use a water bath canner or a pressure canner depends on the acidity of the food to be canned. Acid foods contain enough acid to prevent the growth of unwanted bacteria. These foods include most fruits and tomatoes (although some tomato varieties need to have acid added). Low acid foods, such as meat, seafood and most vegetables do not have enough acid to safely water bath can them.

The method of packing the jars with food is also dependent on the acidity of foods. Most acid foods that will be water bath canned need to be hot packed. That is, the food needs to be hot, and it needs to be placed into jars that are still hot from being sterilized in boiling water. Most low acid foods can be packed either hot or raw.
