A major new study suggests that age-related changes in the uterus may contribute to poorer pregnancy outcomes, with women aged 49 and older experiencing lower live birth rates and higher miscarriage risk despite donor-oocyte treatment. Presented at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE), the findings challenge the assumption that donor eggs can fully “reset” the reproductive clock by eliminating the effects of reproductive aging.

People who speak more than one language seem to have younger brains, according to research presented at the Federation of European Neuroscience Societies (FENS) Forum 2026. Our brains are made up of billions of nerve cells that need to communicate with one another. As we age, connectivity in our brains tends to deteriorate and, as a result, our memory and the speed of our thinking also decline.
