New work on old bacterium shows promise. Bacillus subtilis has been used as a base organism to make vitamins and enzymes for washing powder. Nine countries including Australia have taken an in-depth look at Bacillus subtilis and the way it can survive in different environments. Evolution has made B. subtilis thrive and have a strong metabolism. The findings will enable the creation of metabolites for chemical and pharmaceutical industries. There is greater understanding of how bacteria survive when infection changes the environment. This bacterium is now much more useful in producing enzymes. In the study 512 new genes were identified in B. subtilis . These were added to the 4,200 previously known genes. It was believed that only a few genes needed to be modified to makes changes, but it was found that up to half of the genes needed to be targeted. Despite this it has been a great leap forward in science. http://www.adventure--australia.blogspot.com/ http://www.tysau...

Dinosaur metabolism was not only higher than reptiles, their bodies ran at a faster rate than mammals. Analysis of tiny holes in their bones shows that they pumped a lot of blood through their bodies. So scientists have been wrong for a long time claiming that dinosaurs were slow moving creatures who relied on the sun to get going each day. Tests across a wide range of dinosaurs, big and small, confirm they moved around with ease. Some scientists have accepted the hypothesis that dinosaurs were not reptiles. It makes one wonder how many other things we are taught at schools are totally wrong. New evidence for upright walking of apes goes back more than four million years to an animal with feet designed to climb trees. Their hips are clearly designed for walking upright. And for decades we had been told a special foot design was necessary for bipedal walking. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/Adventu...
