POPSTuberculosis Is 9,000 Years Old
The fact that Alit-Yam is one of the first Neolithic settlements evidenced to have domesticated cattle further goes to show that the bacteria infected humans first and then mutated into its bovine form. Several more skeletons found at the dig site exhibited traces of bacterial cell wall lipids, which have been directly linked to the presence of TB after DNA analysis. Having discovered the first hosts of the TB bacteria, biologists now hope to be able to sequence the bacterial DNA, in the hope that they would find out exactly how it mutated over the thousands of years it lived in humans. Already, several strand portions have been identified in samples collected from the bones in Egypt, which are not present in today's TB strains. This could mean that changes in human physiology may also trigger alternate responses in bacterial morphology. Scientists continue their research, with the big prize being finding a way of ridding humanity of this terrible disease.

POPS500,000-year-old TB case 'found' 500,000-year-old TB case 'found' Scientists say they have discovered in Turkey the most ancient evidence of tuberculosis in a 500,000-year-old human fossil. Experts had thought TB emerged several thousand years ago - based on the remains of mummies from Egypt and Peru. The skeleton is of a young man believed to belong to the first human species to migrate out of Africa - Homo erectus. The dark-skinned Homo erectus, who migrated northward from low, tropical latitudes would have produced less vitamin D, which can weaken the immune system. They found a series of small lesions etched into the bone of the cranium whose shape and location they claim are characteristic of the Leptomeningitis tuberculosa, a form of TB that attacks the meninges lining of the brain. Dr Simon Mays, expert in human skeletal remains at English Heritage, said, until now, the most ancient case of TB recorded was from remains found in Italy dating back 5,000 years.

POPSUniversity's lectures online. YouTube is no longer being just for fun. Nowadays, some universities start to put the lectures and events on YouTube as a videos; so you can attend and learn whatever you want while you get a rest in your home. Do you think Physics or Biology is so hard to understand; let’s try the new YouTube video method from Berkeley University of California on this link http://youtube.com/user/ucberkeley Learn and have a fun.
