Lake Wells in WA Source of Australia's First Potash Production

Australian potash
Potash production has begun in Western Australia at Lake Wells. A research project with the University of Western Australia in the School of Agriculture and Environment will test the potash on various WA soil types, so Australian Potash will be able to more effectively advise Australian farmers.

Bayer Chemistry to Develop New Herbicides

Chemistry: Weeds are becoming resistant to selective herbicides.
Herbicides have officially been used since 1890, though common salt could have used to kill weeds for possibly a thousand years before. The first selective herbicide was identified in 1940. It later became 2,4-D compound and was released in 1946.  Seventy years later we face the problem of weed resistance to selective chemicals. Western Australia can no longer get significant kill of weeds growing around crops. It is costing farmers a fortune.
Ryegrass weed growing in crops
Project Kangaroo has been initiated. It is managed by Australia’s Grains Research and Development Corporation (GRDC) and receives assistance from Bayer of Germany. Money from growers is funding it: they are paying $45 million in levies. The Federal Government is promising money. Knowing how government has behaved recently the project might get a dollar!

Wild radish and ryegrass are the main culprits affecting crops. Glyphosphate was used widely to control these weeds. They are not very effective these days. Chemical companies need to take a new tack and work at the molecular, even atomic level, to find ways of killing selective weeds. Nature though is good at overcoming new things in the environment. It is only a matter of time before evolution beats "unique" obstacles set up by Man.

First-NIght-Effect Means Little Sleep at New Hotel

SAnthropology: we have evolved to be on guard on the first night when sleeping in a new place.
Man is still a hunter. We may live in cities and believe we are advanced but our genes have evolved to survive in the wild outdoors beneath the starlit night sky. If we move into a new environment getting a good night's sleep on the first night is a problem. Our brain is "on-guard" against unknown dangers.
Primitive man sleeps
This phenomenon is in all animals. One hemisphere of the brain will sleep while the other remains on sentry duty. This "first-night-effect" is permanent. There is no cure because it isn't an illness. After the first night the brain adapts, records the new environment and deems it to be safe.

Tests show that the left hemisphere sleeps lighter in a new situation. Slow-wave activity is weaker than the right hemisphere. Furthermore, the default-mode network which involves mind wandering is more active. This indicates that the brain is checking the environment. Sleeping test subjects were played some normal and some unusual sounds. The left hemisphere became even more alert when it heard unusual sounds or even loud sounds. After the first night the brain became "normalized" then no such activity was observed.

Western Adults Have Chronic Raised Immune Responses

People who live in industrialized countries are physically weak when they are attacked by parasites, microbes and viruses. This is because children are increasingly being brought up in clean, sterile environments. If they are not exposed to these dangers as children they could die if "bugs" invade their bodies when they become adults.

In Ecuador, the Shuar people have a high childhood death rate, three times that in Western countries. However, as adults their immune systems are stronger. A group of Shuar adults was tested for inflammatory levels. Some had very low levels. Others had moderately high levels, below the chronic level, probably because they were in the process of becoming ill or had been sick.

Western adults have a generally high level of inflammation, constantly. There bodies fight "minor" infections all the time. Consequently, damage is caused to the body resulting in diabetes, cancer, heart attack and stroke. A Chronic level of inflammation can be a killer.

As susceptible Shuar children die, adults develop the "correct" immune response, only fighting back strongly against dangerous infections. Western adults' immune systems are not "tuned", as childhood minor infections are prevented. Basically, this is why people in developing countries may die in an epidemic, but they can survive an infective environment better than first world adults. Third world adults carry infections and have a mild immune response, when Western people would probably not survive living in such muddy conditions, particularly with the dirty water.
