Researchers have created a new type of pasta called 'anelloni' to demonstrate the complex shapes of ring-shaped polymers. Computer simulations show that these molecules can become tangled and appear frozen in place, potentially leading to a new state of matter called a 'topological glass'.
A review of 90 studies found consistent declines in semen volume and sperm performance, as well as increases in malformed and DNA-damaged sperm with increasing male age. This decline in semen quality is a significant concern for couples delaying childbearing and may contribute to increased infertility rates.
