Model explains menopause timing, shedding light on ovarian aging and fertility

Menopause, driven by ovarian aging and the depletion of ovarian reserves, marks the end of a woman’s fertility, and while many aspects of these processes are well understood, the overall dynamics remain unclear. A new study from Rice University researchers, published in the Biophysical Journal, introduces a novel approach to unraveling the complex patterns of ovarian aging using stochastic analysis, a mathematical approach that examines systems by evaluating all potential outcomes using random probability.

Microplastics in oceans may increase disability risk for coastal residents

Tiny bits of plastic found in the ocean may be tied to a higher risk of disability for people who live in coastal areas with high levels, according to a preliminary study released today, February 25, 2025, that will be presented at the American Academy of Neurology’s 77th Annual Meeting taking place April 5–9, 2025. The study looked at disabilities affecting memory and thinking, mobility and a person’s ability to take care of oneself.
