Dingo is a Mystery to Science

Science: Dingo dog came to Australia via Southeast Asian seafarers.
Archaeological evidence shows that dingoes arrived in Australia 4,000 years ago.  There is no mystery as to who brought them.  Southeast Asian seafarers did land in Australia to get fresh water and herbs to treat constipation.

The dingo is common across the world today, all the way from India to the Pacific islands.  In news videos you see dogs roaming about the street in the background that are absolutely identical to the dingo, same upright tail, same color coat.

People chosen as the distributor of the dingo are the Lapita who moved eastward out into the pacific.  This choice is just for convenience.  It is definitely wrong.  The dog is common everywhere.  Let's face it, Timor is so close to Australia that sailors obviously landed here, often.

Genetic evidence places the origin of dingoes in China.  This is only where the breed began.  It rapidly spread to every country in Asia and Southeast Asia.  The dog is definitely a meat eater though.  It does not have the capacity to digest starch, so it is said that they did not live with agricultural people.  But weren't the Chinese mainly farmers 4,000 years ago?  They still are!  Dingoes are ancestors of modern dogs, not the other way around.

The World's Rice Originated in Australia

Rice came from Asia, more specifically China, right? You would be wrong. Genetic tests on rice grown today show it come from northern Australia. It was clean, uncontaminated and has been pinned down to Cape York in Queensland.

Originally, it was growing wild in the tropics, an unusal place for rice as we associate it with wet conditions all year round. The real question is how did it get to Asia? Obviously, people from Asia came to Australia and took it home.

The Middle East is the cradle of Mankind. For rice it is Australia. Wild rice growing there today is more genetically diverse than anywhere else in the world. Asian domestic and wild rice is inbred. Australian rice is wild. It grows there today unchanged by human intervention. This took place 7,000 years ago.

Australian rice will be the basis of research to improve world food production. It holds the genetic keys to open the door very wide indeed. Modern rice varieties are just little sparks from the fire of the Australian native gene pool. The introduction of genes from Australia is vital to feed the growing world population.

Our Genes Hold the Key to History

History is based on artifacts with huge gaps in the timeline. Academics fill in the spaces and tell us that this is absolute truth. Of course, we are not stupid: we know that much of what happened in the past will never be found. However, real history is in our genes. The "modern" world has only been here for a couple of centuries. we have not changed much from our ancestors when they came out of Africa perhaps 90,000 years ago.
Mongolians invaded europe
Sure, many of us have become paler than those who remained in Africa. Some genes coincidentally related to this have become more prominent in Europeans and Asians. The ability to more easily digest dairy products in an example of related genes. By tracing these genes the human mixing process has become clearer.

Times of conflict increase the mixing process. Tough times in medieval Europe and the Crusades in north Africa were such eras. A reverse mix occurred when north Africans moved into Spain. It has come to light that immigration took place from Mongolia into Europe before Genghis Khan. Nothing is recorded in the history record about this. History is surely the life of conquerors. waves of human movements are not there. Genes hang around in our bodies. Many come along for the ride, just waiting for an opportunity to "activate".

Ships' Ballast Water Spreads Marine Creatures

As international trade continues so does "equalization" of the planet. Many marine species are now found in all waters of the world. This is because transport ships literally hoover up animals in ballast water, which is released at any time, any place, when it is no longer needed.
Ship releasing ballast into a port
All ballast water is released into a port when cargo is taken onboard. Marine survivors of this rough treatment give the local environment a go. Some are successful and multiply to epidemic proportions. Zebra mussels and Pacific seastars in particular are a major problem.

An Australian study gathered data such as ports where ballast was likely to be taken on and where it would probably be released. Marine species spread this way were identified and it was predicted how long they would survive. This data was fed into a computer.

It was noticed that shipping volume was increasing mainly in the transport of primary products. Most of this Australian export was delivered to Asia and Southeast Asia. This meant that marine species from this region were unloaded into Australian waters.

New laws were introduced in 2001 to ban the emptying of Asian ballast water into Australian seas. The new rules have been totally ignored. Furthermore, the International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWMC) directed ballast water be unloaded into holding tanks. Shipping is not complying.

Hope for Ebola Vaccine

Ebola is still a world crisis. Though the overall rate of infected people has slowed, some pockets in Africa have increased infections. It could still spread to Europe, Asia and the US.  If it does spread this wide, control will be virtually impossible.
Some form of effective treatment has to be found - fast. The blood of survivors has been seen has the most probable source of a vaccine. However, any form of treatment should be examined for its usefulness.

In Australia a vaccine tested on monkeys holds out great hope. The Kunjin treatment has been created from engineering the Ebola virus protein. Monkeys were given the vaccine and they showed significant protection from the disease. Seventy five per cent of the monkeys kept their resistance.

Much research was based on tests on rodents. Success on them did not mean that vaccines would work on humans, so tests on primates is beginning. Scientists must get a move on to create a successful vaccine. Ninety per cent of infected people die.

Bad Weather From Climate Change Becoming Accepted

It seems the first signs of general acceptance of extreme weather from climate change are forming. Some scientists are openly declaring that change in weather patterns will be permanent or worsen as climate change takes hold. This past year has been one of the wettest on record in eastern Australia. This is blamed on damage to the environment by human activity.

Change is regional with heavy rains in Europe, east Asia and Oceania. The US and Africa were very dry. Greenhouse gasses caused a warming of oceans. This put more moisture into the atmosphere to fall as rain in the large land masses of Europe, Asia and Oceania. A downpour occurred in New Zealand that was a once in 500 years event.

Just  why the US remains dry is a problem. It should have received more rain, but weather patterns tends to vary around the world due a balancing effect in humidity. Hurricane Sandy indicates the probable future damage from extreme weather due to climate change. Rising sea levels increases destruction. Such events affects people for the rest of their lives.

The Climate Changes in 20-30 and 50-70 year Cycles

Climate change is not all one way. There are cycles. Research on coral areas has shown two cycles, 20-30 years and 50-70 year. The region tested is in the northern Pacific which has a strong influence on Asian Monsoons. The amount of rainfall can vary a lot.

In regard to Australia, the climate varies across the continent. Western Australia is usually out-of-kilter with the rest of Australia. When there are floods in the east there are droughts in the west.

The cycles were discovered by drilling out cores and examining the undersea strata with ultraviolet light, a process called Spectral Luminescence Scanning.

Findings have helped to clarify changes in the climate of Madagascar since 1950. Changes in rainfall and river run off have left their mark. Cycles can be traced as far back as 1708.

New Mustering System to Revolutionize Farming

Cattle mustering has always been a manual labor enterprise.  Little has changed for centuries.  Some minor improvements have occurred but the new Remote Livestock Management System (RLMS) developed by Precision Pastoral Pty Ltd is a leap forward to more efficiency. 

Computer Hardware and software are combined in a practical control method.  All animals have to drink.  When Cattle drink at a watering point they are guided through a pathway that identifies, weighs and drafts animals into particular holding pens.  Those who are not ready for market are automatically released back into the paddock.  The system is solar powered so there are virtually no running costs.  Cattle tags are easily read.

Growth rates, calving and fertility are all monitored.  Feed supplements can also be effectively regulated.  This will improve profitability for farmers.  They have been waiting a long time for something like this.  Degradation in rangeland can be solved by relocation into new pastures via the gates.

The new computer mustering system is seen as a revolution in cattle and sheep production.  There are strong prospects for its adoption in north and south America, Asia and Africa.

New Illicit Drugs Are Frequently Created

The world is in crisis. Illegal drugs that permanently damage users are easily purchased online. Recent research shows that when those under 16 years of age take marijuana regularly, particularly the cultivated strong variety, they are irreparably set back for the rest of their lives. Schizophrenia, is common. Furthermore, There is up to 55 per cent reduction in memory recall and decision making skills. A problem not given much importance is lung disease from smoking marijuana.

Dangerous psychoactive drugs are being developed. They are very pure and untested on humans. Some are highly toxic. Because they are new there are no laws restricting their supply, so they can be openly sold in Australia. Buying drugs online is virtually anonymous. The law has limited mechanisms for checking sales.

Several new chemicals are combined into a very dangerous brew. Some normal antidepressants are also added. The affects of drug interaction is unknown. Products are not checked for consistency. A brand bought one week can be completely different the next. Being legal in the short time does not make "home produced" drugs safe. Users believe that the new drugs are created in Australia. This in really not the case. Most are developed in China and India. These producers are untrackable. They do not use local currency. Barter is commonly practised.

Despite the wide choice of drugs, cannabis is the preferred substance of abuse. It is easily ingested by smoking, but it has a very strong smell that lingers for a long time after use. Police know when a person has smoked the illegal substance when they smell it. The chances of being caught are high.
