Women who enter menopause early may age faster than women in whom menopause arrives later, said a study Monday that could help pinpoint women at highest risk of age-related diseases. The findings could settle a long-standing debate, said Steve Horvath, a professor of human genetics and biostatistics at the David Geffen School of Medicine at the University of California, Los Angeles. "For decades, scientists have disagreed over whether menopause causes aging or aging causes menopause," said Horvath, senior author of the study in the Proceedings of the National Academy of Sciences.
Any military or intelligence cooperation between the United States and Russia to strike targets in Syria would include measures to ensure U.S. operational security and would not be based on trust, a top U.S. military official said on Monday. U.S. Secretary of State John Kerry said on Friday that he would meet his Russian counterpart in the coming days to discuss an American proposal for closer military cooperation and intelligence sharing on Syria. The proposal, which Kerry hopes to conclude within weeks, envisions ways in which Washington and Moscow would share intelligence to coordinate air strikes against the al Qaeda-affiliated Nusra Front and prohibit the Syrian air force from attacking moderate rebel groups.
