Horse dung may save your life

Copper metal kills bacteria. Copper plated push plates on doors cut infections.
Horse poop has long been known as great for gardens, but save your life? Mushroom growers know that horse manure is ideal for producing those delectable morsels. A mushroom of a different kind – the inky cap(Coprinus comatus) has researchers hot on the trail of a new antibiotic.

The promising new compound is copsin, a protein substance that interferes with cell wall formation. Bacteria have cell walls. Scientists are reproducing the substance via genetically modified yeast. It is a long way from growing yeast in small scale batches to industrial production and clinical trials.

Medical researchers have been sounding the alarm about multi-resistant bacterial infections. Gradually, as an antibiotic comes into widespread use, it loses its ability to kill bacteria. When penicillin was first produced it could wipe out nearly any infection, revolutionizing modern medicine. 
Other fungal based bacteria killers also came on line to help fight disease. But over time, bacteria have evolved resistance to the compounds.

The situation has not been helped with careless prescribing of antibiotics for people. But 85% of antibiotic use in N. America is used in the agriculture industry. From feeding animals to produce faster weight gain to spraying on fruit crops to keep the spots off, by far the greatest use of antibiotics is in agriculture.

Other names for inky cap:  lawyers wig, shaggy mane

Shaggy mane mushrooms are also nematode killers. They are able to kill and digest small round worms. Organisms in the Fungus Kingdom exhibit characteristics like plants at times, and at other times exhibit animal like characteristics.

Abandoned Oil Pipelines What Lurks Below?

Image
These photos were taken July 2012 in the historic Turner Valley, Alberta B. McPherson Controversy over new oil pipelines is reaching boiling point in many circles. Heated debate is taking place over the proposed Enbridge Northern Gateway and Keystone Pipeline proposals. Safety, disruption to landowners  and more are being weighed against the money to be made transporting and selling petroleum products. It got me thinking about the old pipelines. What happens to a pipeline when it is too old to use or not needed? It’s a bit of an Alice in Wonderland scene. The US laws and regulations are different from ours in Canada. The Pipeline and Gas Journal is a source of information about abandoned pipelines in Texas. Apparently a pipeline in Texas may be abandoned by a company, but it still retains ownership and may choose to reactivate the line at a later date. In the meantime, the right of way or easement is no longer maintained, but the through which the pipe extends is not ...

Prince Rupert Says No to Enbridge Pipeline

Image
B. McPherson Prince Rupert city council joined a growing list of BC coastal communities that are saying “No” to the Enbridge proposal to build a twinned pipeline from Edmonton to the coast. The decision of the Prince Rupert city politicians was unanimous. Already the village of Kitimaat, Terrace and the Skeena Queen Charlottes Regional District have voiced their opposition to the project. There are ongoing hearings by a federal court appointed Joint Review Panel which are gathering input from interested parties about the proposed Enbridge Northern Gateway Pipeline which would bring crude petroleum from the oil sands of Alberta to the coast of British Columbia. The proposal would see a twinned pipeline run over the Rocky Mountains and through wilderness to the treacherous west coast. The proposed terminus at Kitimat would require tankers to wend their way through the maze of islands and reefs to load up at the head of Douglas Channel. While the hearings and the finding...

Scientists Beginning to Sound Warnings About Atmospheric Nitrogen Compounds

Image
B. McPherson                                                 This short film explains very well the greenhouse effect on Earth. While the world is focussing on the production and release of carbon dioxide into the atmosphere, other gasses are quietly adding to the catastrophe. Methane is a potent greenhouse gas and nitrous oxide is 300 times more efficient at keeping the Earth warmed. While much of the Earth’s atmosphere is made up of the element nitrogen, it is the nitrogen in reactive compounds that is starting to worry atmospheric scientists. The Green Revolution was made possible by the industrial production of chemical fertilizers. It, combined with antibiotics has allowed the Earth’s population of humans to swell from 1.6 billion at the beginning of the 20 th century to seven billion this year. Nitrogen is a key nutrient in plant growth. Unfor...
