Agriculture Was Brought into Western Europe by Southern European Males

Learning has not been linear for human beings. Advancement can be different from one place to another. It is now known from DNA analysis of 5,000 year old skeletons in a French cave that women did not travel into western Europe. Mitochondrial DNA is passed down only from the mother which shows that European women had local ancestry. On the other hand the Y chromosome passed down through males shows movement of males into new European regions. Knowledge of farming came into new areas when the males moved in and mated with local females. Analysis of DNA from 29 skeletons found in France, highlighted this difference between the mitochondrial DNA and Y chromosome. Males had moved from the Mediterranean to western Europe. Most of the males in the 29 skeleton group were related, so when the males arrived they stayed on the land with their new hunter gatherer wives. The southern males had a problem: they did not have the lactose tolerant gene of central Europeans. They had to drink f

Blue Straggler Stars Found in the Milky Way Bulge

We now know that dark matter exists. NASA's Hubble Space Telescope has also identified blue straggler stars in the Milky Way. These stars don't show their age. Their color hides their true age. This is the first time they have been found in the core of the Milky Way. Not much is known about blue stragglers. Accepted theory is that they develop from binary pairs. The larger of the pair strips material from the smaller one. Hydrogen is activated which causes the larger star to undergo nuclear fission thus making the star blue. Blue stragglers are rare in the Milky Way because the central bulge of the system stopped making new stars billions of years ago. Aging stars and cool red dwarfs exist in the Milky Way now. Giant blue stars were thought to have exploded into supernovae in the distant past. The presence of blue stragglers throws a spanner into the works of current models of star formation. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspo

It May Not Be a Wise to Take Polypills

As if we aren't taking enough medication, "combination" pills are now being made. Normal healthy people don't need to take "just in case" medication. After all anyone could be knocked down by a car and killed. Furthermore, many medications clash with each other producing dangerous chemicals when mixed. The latest polypill is for heart attacks. It contains statins, aspirin, and two blood pressure drugs. Tests show that the incidence of heart attacks can be reduced by half if the multi-pill is taken regularly due to lower cholesterol and blood pressure. It is also claimed that colon cancer will be less frequent in test subjects, which seems rather odd considering the slim relationship between cholesterol and cancer. If a person is fit and healthy it would probably be wise to leave things as they are because all medications have side effects, and tests done so far are only looking at short term results. Tests were only for 12 weeks. How can one draw such
