Researchers figured out how the ancestors of modern horses migrated

Credit: UrFU An international research team determined that ancestors of modern domestic horses and the Przewalski horse moved from the territory of Eurasia (Russian Urals, Siberia, Chukotka, and eastern China) to North America (Yukon, Alaska, continental USA) from one continent on another at least twice. It happened during the Late Pleistocene (2.5 million years ago - 11.7 thousand years ago). The analysis results are published in the journal. The findings and description of horse genomes are published in the journal Molecular Ecology. We found out that the Beringian Land Bridge, or the area known as Beringia, influenced genetic diversity within horses and beyond, said senior researcher at the Ural Branch of the Russian Academy of Sciences and the Ural Federal University (Russia) Dmitry Gimranov. Owing to the appearance of this land part, the flow of genes among mammoths, bison, and wolves could occur regularly. And if 1-0.8 million years ago horses from North America were n

Corruption in healthcare worsens the health of patients and the quality of nutrition

Credit: UrFU Bribery in the public healthcare does not solve the problem of poor quality of services, and even exacerbates it, researchers argue. The same can be said about the well-being of patients and their own assessment of health. In other words, bribes in the healthcare do not provide good quality services and do not pay off. Such conclusions were reached by an international team of researchers, including Olga Popova, the article s co-author, an associate professor at the Ural Federal University (UrFU, Russia). Researchers examined survey data on 41,000 citizens from 28 post-communist countries in Central and Eastern Europe, as well as the former Soviet republics, including Russia (information provided by the World Bank and the European Bank for Reconstruction and Development). The research results were published at the
