Non-Human Primates had Brain Language Pathway

Until recently the earliest language pathway was believed to have originated 5 million years ago. However, it seems that the auditory system was evolving toward language in nonhuman primates 25 million years ago. This conclusion was reached after brain scans of humans, apes and monkeys. The auditory system found in other primates is an evolutionary forerunner of the human language pathway. Therefore, there is a clear evolutionary path toward auditory cognition and vocal communication. Language capability is nascent in nonhuman primates. Proof of early language development was there all the time but was never understood before. Analysis of the human brain shows a strong structure on the left side of the language pathway. The right side has changed from what it was in other primates: it has diverged into non-auditory parts of the brain. It is now believed that the path to language capability began more than 25 million years, probably in preprimate animals. Brain scans of n

Rust Genetics Now Understood After 30 Years of Research

Wheat rust is continuing to destroy wheat crops. Up to 70 percent of a farmer's crop can wilt due to rust. A disaster is just around the corner as a third of the world's population in all climates relies on this commodity. Csiro, the University of Sydney, John Innes Centre (UK) and the National Institute of Agriculture Botany (UK) have identified three key genes that sustain the disease. Research has brought to light how the genes work in stripe rust. All three genes were cloned using mutational genomics. Editing of genes could make wheat genes that are susceptible to rust become active again. They could then fight the disease. Much more work needs to be done but the future looks bright. ch genes yu rust or wheat sh zhang fe resistance = an genes eh rust er wheat do zhang st resistance jo gene mi stripe al csiro re university = up genes by rust aa wheat so zhang ba resistance of gene bi stripe to csiro if university za research be sydney ob work et scientists l

French Researchers Examine 18th Century Color Photographs

It is accepted that early photography was a difficult path for an enthusiast to take. Cameras were bulky and heavy. The person who took photos had to be a virtual specialist chemist. It is so different from the ease of trapping a moment in the present. A pioneer in this field was Ducos du Haurun a brilliant Frenchman. He took color photographs. Three different colored filters were used to capture negative shots developed on gelatin film. The yellow, red and blue layers were then assembled to produce a single print. Over time, Ducos du Hauron introduced practises to speed up the process. French investigators have analyzed some of the 18th century pictures. They used x-ray florescent spectroscopy, synchrotron-based infrared (IR) spectroscopy and Raman spectroscopy to determine the chemicals used as pigments for the different colors. Photographs taken in 1878 showed that Prussian blue was the ingredient used for the blue gelatin layer. Carmine lake was the foundation pigmen

Research has not Progressed Since HIV Patient was Cured

A cure for Aids became possible for a patient, but Medicine has not progressed from that time. research progressed research It's a miracle: a man is cured of HIV, the only man in the world ever to be cured as a matter of fact. This has not been replicated since. The patient was an American who was treated in Germany in 2007 for leukemia.   ⎳ research a progressed a since a With a hiv a patient a cured ⎳ research progressed hiv The treatment involved a stem cell transplant. A rare genetic mutation called CCR5-delta 32 was in the DNA of the donor. It was this that cured the disease. You would think a quest would have begun for other carriers of the useful molecular sport. Sadly, it was not done. The search continues for a cure by traditional chemical methods.

Vanuatu People a Shock to Anthropologists

Vanuatu ancestors were from Taiwan and the Philippines. A discovery has sent shock waves through anthropology. The ancestors of Vanuatuans were put in the pot of Pacific Islanders. People of this island do not look like Asians. However, DNA tests on the oldest skeletons found show that the island's first arrivals came from the Philippines and Taiwan only 3,000 years ago. It seems that Australian Aboriginals and New Guineans were not keen to venture out onto the high sea, though Pacific islands were much closer to them than it was for Southeast Asians. Scientists say Papuans moved their later to produce the modern Vanuatuan gene pool. There is a problem here. Combining the facial features of say Filipinos and Papuans does not produce modern Vanuatuans.  There was earlier movement westward across the large ocean of people from South America. Pacific islanders of South American descent obviously arrived in Vanuatu at some time. ◆ Antrhopology by Ty Buchanan   ◆

New Theory - Tuberculosis Arose From Adoption of Fire

Fire caused tuberculosis according to new archaeological theory. Evolution is very powerful. A change in climate leads to the survival of those who suit the new climate more adequately. A series of ice ages meant hairy people with narrow nasal passages (to warm the damaging cold air on it way into the lungs) passed on their genes. People living in central Africa remained in a warm climate, so they did not have to adapt. A new premise is that the adoption of fire by early humans caused the emergence of tuberculosis. Apparently, many people crouching around a fire set the ideal conditions for TB to take hold. Just a minute though. Didn't Africans also cook meat on fires and kept near to it for warmth on cold nights? They certainly did. No, this new theory does not hold up. It is assumed that TB is mainly a thing of cold climates.  More correctly, molecular archaeological evidence shows that TB began in Africa. Just how scientists reached the conclusion that humans

Vegemite Beer Could be the New Product

Vegemite beer could be good for society. There is a myth about Vegemite. It is assumed by many Australians to be unique. This isn't the case. Marmite and Bovril are the same product. It is yeast residue, the stuff at the bottom of the container when you brew your own beer with a lot of salt added. Of course, the yeast is dormant and can still be activated. This is the case despite Vegemite spread being sterilized. The tasty "treat" is banned in Victorian prisons because it can be used to make an alcoholic concoction loosely called beer. Scientists actually made beer with Vegemite to prove that this is possible. Vegemite acted as a booster in the fermentation process. This made it possible for basic raw materials to be used to make beer. There is one proviso: some natural yeast has to be obtained from somewhere else. Yeast naturally occurs on the skin of fruit and berries, so it is easy to get.  Just get some flour and add water.  It will start fermentin
