open
Health & Biology
Fertility treatments like IVF help many people conceive, but success rates still drop significantly with age due to biological factors that current medicine can't fully reverse. Understanding and addressing this decline remains incomplete.

Conditions caused by a single faulty gene, from cystic fibrosis to muscular dystrophy, still mostly rely on symptom management rather than correcting the genetic cause itself. Gene therapy shows promise but remains far from a widely available cure.
