Scientists Find Three Viruses to Control Cane Toads

Cane toads are a pest in Australia. They were introduced to kill beetles attacking sugar cane. Unfortunately, they were not interested in the beetle. They ate just about everything else. Native species have been greatly depopulated. Now, their DNA has been sequences. Furthermore, three viruses that destroy only cane toads have been identified.

Anthropologist Johann Friedrich Blumenback promulated a concept that changed the way members of societies thought about the structure of Mankind for generations. Unfortunately, the belief was absolutely wrong. There are no races. Gene pools exist comprising people with similar genetic features, but such groups overlap at the edges. | ▶ not stories news. |◀ |
Races
Much suffering has been caused by imperial governments applying the theory across the world. It was the substantive driving force in colonialism. Slavery was condoned because of the premise. Even genocide was be carried out because of it. The level of intelligence is about the same for all humanity. Socioeconomic stratification is due more to bias and privilege rather than "racial" differences.  | ▶ | australian| ▶ |    

Even today, however, writers still divide humans into races in prose. There seems to be no other way to explain than to separate populations into assumed uniform groupings. This is why it persists. Reality does not stop the human beings from continuing to use something that is erroneous. | ▶ | not. | ▶        | ▶ | not | ◀ |

New Theory of Anthropology is Not Strong

New theory on Australian Aboriginals - Anthropology.
Australian Aboriginals split from Eurasians and moved south into the dry continent. Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory.  But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans. The other was very slight and shorter. It is the latter that predominates today.
Papua New Guineans

Australian Aboriginals
Some scientists still hold that there was only one move out of Africa. This is an unsustainable supposition. The doors for movement were always open. Australian Aboriginals were quite unique. It seems that they were the first to leave Africa. There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stolen from rivals if a fire went out.

Mainland Aboriginals have genes different from other peoples. In Europeans, for example, females genes are much the same. The genes of Aboriginal mothers vary between geographical groups. This indicates that males moved while females stayed in the same location. However, divergence is the norm for humans. Unlike other apes who tend not to move at all and remain genetically "static".

Genetic Resistance by Tasmanian Devils to Facial Disease (DFTD) - Biology

Biological research shows genetic resistance to Tasmanian devil disease.
The Tasmanian devil is an animal unique to Australia. It Once resided all over the continent. Perhaps is was easy for Aboriginals to catch for food. It cannot run very fast. It could just have died out due to a warming of the country. Tasmania is its only natural home today.
Tasmanian devil facial tumor disease (DFTD
Their raucous cries led to them being named devils by European settlers. They are violent to each other though attacks on humans are virtually non-existent. Scavenging for food is their number one priority.

A facial disease began in the species in 1996. It was unusual in that it is the only known cancer transmitted from animal to animal. Tasmanian devil numbers fell by 80 per cent in twenty years due to Tasmanian devil facial tumor disease (DFTD).

Extinction was predicted. However, it was noticed that some animals survived without getting the disease. Genes were examined and these devils had five genes not present in their brothers who succumbed. This shows that all animals currently living are unlike their ancestors who dominated even a hundred years ago.

GM Not for Food Okay for Health

Genetic modification is favored in health but not for food.
Convincing people to eat genetically modified food still has a long way to go to gain majority acceptance. Yet, just about everyone is in favor of using gene technology to treat health problems. This is a strange anomaly. Gene manipulation of any kind will change the world we live in. Once a change has been made and it spreads through the environment it is there forever.
The case against genetically modified crops, GMCs
Drug companies admit they have lost the war in Europe. There is no way that GM food will ever be accepted there. It is largely an emotional decision, not scientifically based. Possibly, in the near future, Europe will ban DNA experimentation in health as well. This will be counter-productive. If money is invested in nations that welcome gene science then the environment will change anyway because we all live in the same world.

There is a major problem looming, however, on the real future of genetically modified crops. To be profitable farmers must use Monsanto's Roundup. This is losing its effectiveness, particularly in Western Australia which has recently relaxed laws restricting GMCs. The cart isn't much use without the horse.  Even crops modified to be resistant against glyphosate could become weeds in the future.  Unless a new effective herbicide is developed soon the industry will not attract investors - potential profit drives everything.

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.

For 50,000 Years Australian Aboriginals Were Genetically Pure

Genetics: Australian Aboriginal stone tools use was made within the Aboriginal gene pool.
Australian Aborigines have been isolated on this vast continent for 50,000 until Europeans came and messed everything up. DNA sequencing shows Aboriginals were pure for this whole period.

Contrary to the view held by many scientists for centuries, people did not arrive from India 4,000 years ago. Seafarers from India and Southeast Asia did stop here to get fresh water and herbs to treat constipation. Yes, this is true.
Australian Aboriginal stone bladed knife

Data tracing the Y chromosome from father to son shows no Asian genes in their profile. Aboriginals were the first people out of Africa. Once they reached Australia no more came from Asia. The out of Africa theory has now been pushed back 200,000 years. There is no real evidence of where these people went as far back as that.

Tasmanian Aboriginals are a mystery. All have now died out so we will never know if they came here before mainland Aboriginals. Their DNA could have been different to mainland Aboriginals. They certainly did not know how to light fire. "Flames" were stole one to the other.

It was thought that because Aboriginals had an abrupt change in culture particularly in regard to stone tools that there must have been an outside influence, but this wrong. The change was made within the Australian gene pool.

Biology: Atlantic Molly fish of Mexico survive high hydrogen sulfide acid.
There is hope for the future of fish as the world is polluted more every day. Some fish can live in extreme toxic, acidic environments. For example, the Atlantic Molly fish of Mexico can survive high levels of hydrogen sulfide acid. They are the only fish in volcanic freshwater springs.
Atlantic molly fish

Mollies do not filter out the toxin. They turn on certain genes that do the filtering job for them. Of the fish's 35,000 genes 170 are enhanced in the process: these linked genes are all involved in removing hydrogen sulfide.

If things get serious and species of fish begin to die out, this group of genes could be "spliced" into the gene structure of endangered fish. They would not be the same fish, but at least some vestige of the evolutionary sequence of dying fish would live on.

No More Poppies Needed to Produce Narcotics

Scientists have found a way of transforming ordinary sugar into hydrocodone. This will lead to a cheaper way of manufacturing opiates. Unfortunately, it will also make things easier for drug traffickers selling a cheaper product,
Hydrocodone made with yeast as catalyst
Yeast changes sugar into pain killer. This takes out the entire one year growing season for poppies and the factory process itself. At present, 4,400 gallons of yeast is needed to produce a small amount of hydrocodone. Work will proceed to improve this.

With yeast as the catalyst, it looks like plant-based medication manufacturing is under threat. Yeast has snippets of DNA added to reprogram cells into target compounds. Notably, a third of the world's supply of the medication artemisinin is already produced from modified yeast. Artemisinin needs six genes while hydrocodone requires 23. Some genes from rats arehydrocodone.
put into the yeast to make

A "halfway-house" way of manufacturing pain killers is possible. A strain of yeast to make thebaine is available. It has to be processed in a factory to create the thebaine opiate, but it is cheaper than using poppies and is quicker.

Female-Only Epilepsy

Many children have a form of epilepsy that is genetic, handed down from a parent. Female-only epileptic syndrome is a case in point. It is rare but it remains a debilitating problem.  At birth babies seem to be normal, but in a few months they begin having seizures.
eEpilepsy in girls
Australian scientists have pinned down the genetic mutation responsible for its expression. Professor Gecz says that the 19 (PCDH19) gene is the mutation triggering the ailment. Females have two X chromosome which determines their sex. This duality of X triggers epilepsy in girls.

The main issue with female-only epilepsy is that it causes intellectual disability because seizures cause damage. A deficiency of the allopregnanolone hormone is the main factor in the onset of the ailment. This is an effect caused by the genetic disposition. When the hormone is brought back into balance at puberty permanent damage has already been done. The research continues.
