DNA ties Ashkenazi Jews to group of just 330 people from Middle Ages

Posted: Published on September 10th, 2014

All of the Ashkenazi Jews alive today can trace their roots to a group of about 330 people who lived 600 to 800 years ago. So says a new study in the journal Nature Communications. An international team of scientists sequenced the complete genomes of 128 healthy Ashkenazi Jews and compared each of those sequences with the others, as well as with with the DNA of 26 Flemish people from Belgium. Their analysis allowed them to trace the genetic roots of this population to a founding group in the Middle Ages. Ashkenaz in Hebrew refers to Germany, and Ashkenazi Jews are those who originated in Eastern Europe. (Sephardic Jews, by contrast, are from the areas around the Mediterranean Sea, including Portugal, Spain, the Middle East and Northern Africa.) About 80% of modern Jews have Ashkenazi ancestry, according to the Hebrew University of Jerusalem. Albert Einstein was an Ashkenazi Jew, as were Gertrude Stein and Carl Sagan. Steven Spielberg and Scarlett Johansson are also Ashkenazi Jews, along with three current members of the U.S. Supreme Court (Ruth Bader Ginsburg, Stephen Breyer and Elena Kagan). Despite their close ties with Europe, no more than half of their DNA comes from ancient Europeans, … Continue reading →

Less effective DNA repair process takes over as mice age

Posted: Published on September 10th, 2014

PUBLIC RELEASE DATE: 9-Sep-2014 Contact: Peter Iglinski peter.iglinski@rochester.edu 585-273-4726 University of Rochester http://www.twitter.com/UofR As we and other vertebrates age, our DNA accumulates mutations and becomes rearranged, which may result in a variety of age-related illnesses, including cancers. Biologists Vera Gorbunova and Andei Seluanov have now discovered one reason for the increasing DNA damage: the primary repair process begins to fail with increasing age and is replaced by one that is less accurate. The findings have been published in the journal PLOS Genetics. "Scientists have had limited tools to accurately study how DNA repair changes with age," said Gorbunova. "We are now able to measure the efficiency with which cells in mice of different ages repair DNA breaks at the same place in the chromosome." Gorbunova explained that when mice are young, the breaks in DNA strands are repaired through a process called non-homologous end joining (NHEJ), in which the damage is repaired by gluing the DNA together with no or very little overlap. However, Gorbunova and Seluanov found that NHEJ began to fail as the mice got older, allowing a less reliable DNA repair processmicrohomology-mediated end joining (MMEJ)to take over. With MMEJ repairs, broken ends are glued together by overlapping … Continue reading →

Arab Chemistry Olympiad ignites intense competition

Posted: Published on September 10th, 2014

The Seventh Arab Chemistry Olympiad hosted by the Ministry of Education in collaboration with the Saudi Chemistry Society and Arab Federation of Chemists has seen intense competition between the participating boys and girls. Minister of Education Prince Khaled Al-Faisal opened the event in the presence of Madinah Gov. Prince Faisal bin Salman on Sunday. It features several education and scientific events on various branches of chemistry and has clearly been a learning experience for students. The Arab countries are represented by 136 boys and girls accompanied by 34 chemistry teachers. The organizing committee has also scheduled other events including morning and evening visits to historical sites in Madinah including Uhud Mountain, Two Qibla Mosque, the Trench, Quba Mosque, Maraza Al-Iman exhibition, Holy Quran printing press and shopping trips to malls. The supervisors of the delegations also visited Taiba Secondary, Dar Al-Qalam Center, educational museum and the Hijaz Railway station. The women supervisors were taken to the Madinah Historical Museum and Holy Quran printing press. A cultural and heritage carnival called Madinah Nights was also organized to entertain the Arab delegations at the Ansar Sports Club. The events gave a glimpse of the life of people in the city in the … Continue reading →
