Perspective is Everything

You can't talk about the ocean
with a frog who lives in a well;
he is bounded by the space he inhabits.

You can't talk about ice
with an insect who was born in June;
he is bounded by a single season.

You can't talk about Tao
with a person who thinks he knows something;
he is bounded by his own beliefs

The Tao is vast and fathomless.
You can understand only by stepping
beyond the limits of yourself.


From the Chaung Tzu. 17
via Stephen Mitchell, The Second Book of the Tao.

What fires together wires together

I’m reminded of a case study that describes an individual who had come to associate sexual arousal with being covered in insects. As a child, that individual had been locked into closets for unimaginable amounts of time, and during those times, bugs would frequently fill the space and crawl on him. The child, trying to seek some sort of escape from the reality of his experience, found comfort only in sexual release—even though he was too young to even know what sex was or meant. His body knew only that it felt good, and it provided the only possible escape available to him. In his mind, those associations became, quite literally, wired together.

Why Dirt Helps Wounds Heal

In the field, some practitioners will pack an open wound with black soil to help it heal. You can get black peat that is used for this purpose and others. It is not pasteurized or sterilized in any way; it is full of living organisms. After the battle of Shiloh in the US civil war, soldiers whose wounds glowed in the dark had better survival. The organism (Photorhabdus luminescens) that was growing in their wounds came from the guts of nematodes living in the soil. Presumably this organism outcompeted the pathogenic ones. This kind of antibiotic mechanism cannot be ignored when antibiotic drugs are increasing ineffective.

QotD: the Right Word

The difference between the right word
and the almost right word
is like the difference between lightning
and the lightning bug.

Microbiology: African Sleeping Sickness

Sleeping sickness aka African trypanosomiasis
--parasitic disease in people and animals
--caused by protozoa of genus Trypanosoma
--transmitted by the tsetse fly
--endemic in certain regions of Sub-Saharan Africa (36 countries and 60 million people)
--estimated 50,000 to 70,000 current infx
--3 major epidemics: 1896–1906, 1920 and 1970.
--tse tse flies mainly found by rivers and lakes, in gallery-forests and in wooded savannah
--Sleeping sickness occurs only in sub-Saharan Africa in regions where there are tsetse flies that can transmit the disease.
--For reasons that are so far unexplained, there are many regions where tsetse flies are found, but sleeping sickness is not.
--Worldwide, 25,000 new cases of both East and West African trypanosomiasis are reported each year
--World Health Organization says it is vastly underreported.
--Human African trypanosomiasis (HAT)
--caused by flagellate protozoan, Trypanosoma brucei, which exists in 2 morphologically identical subspecies: Trypanosoma brucei rhodesiense (East African or Rhodesian African trypanosomiasis) and Trypanosoma brucei gambiense (West African or Gambian African trypanosomiasis)
--Both parasites transmitted to human hosts by bites of infected tsetse flies (Glossina species)
--tse tse flies are found only in Africa

...the central nervous systems of American cockroaches produce natural antibiotics that can kill off bacteria often deadly to humans, such as methicillin-resistant Staphylococcus aureus (MRSA) and toxic strains of Escherichia coli, scientists said this week.

not to be confused with African trypanosomiasis which is caused by T. brucei gambiense and T. brucei rhodesiense and transmitted by Tse Tse flise

Wednesday

In the distance a metal machine is banging rhythmically and ringing with a medium tone. The radio is playing the BBC program World Have Your Say, on why nobody seems willing to criticize Obama. I am willing. He just doesn't tell me enough specifics for my criticisms to be anything more than not knowing his intentions or character, and being fairly certain that like the other republicrats he is unlikely to make the really big forward-thinking changes that we need to make in the way our nation is run. He's not talking about our national debt, bankruptcy and failing currency, our impending inability to fund medicare, medicaide and social security, our overextended and unpopular military presence in 130 nations. Did you know that we have 75,000 troops stationed in Germany? How long has it been since we have been at war there? What are we DOING?? ....Obama is not talking about the stuff that I care about, so I don't trust him. I don't think he has the guts to buck the system. I think he wants a long and glorious political career, and that means following the rules.
