Discovery: genes start mutating soon after conception
According to a new study carried out by scientists of Yale University and the Mayo Clinic, hundreds of small genetic mutations start mutating in the cells of the embryo after conception. Many of these mutations occur in the embryo when sex cells are formed. This means that these mutations can become a part of the genome and be transmitted to the next generation, UPI.com reports.
Genetics have told how many mutations the human’s brain accumulates during the life
As Vesti.ru notes, scientists of Yale University and Harvard have calculated how many mutations the human’s brain accumulates during the life. The scientists have studied both embryos and adults. The experts from Yale have evaluated the dynamics of mutations in embryos. DNA analysis has shown that young neurons contain 200 to 400 genetic variations scattered along the whole DNA chain.
American scientists have discovered a new method to enhance the effect of antibiotics
This method of the Massachusetts Institute of Technology and Harvard University is able to cure even the most antibiotic resistant bacterial infections, Xinhua reports. In particular, the scientists were interested in increasing the sensitivity of pathogens to quinolones (antibiotics are often used to treat infections caused by Escherichia coli and Staphylococcus aureus).
