C.F. Richter developed the Richter scale in 1935, a logarithmic scale used to measure the magnitude of earthquakes. This scale quantifies the energy released at the earthquake's source, providing a way to compare the size of different earthquakes. The Richter scale has since been largely replaced by the Moment Magnitude Scale (Mw) for more accurate measurements, especially for larger events. Nonetheless, Richter's work laid the foundation for modern seismology.
Cystic fibrosis (CF) is a genetic disorder caused by mutations in the CFTR gene, which is inherited in an autosomal recessive manner. This means that a person must inherit two defective copies of the gene, one from each parent, to develop the disease. If both parents are carriers of the CF mutation, there is a 25% chance with each pregnancy that their child will have CF. Carrier testing and genetic counseling can help determine the likelihood of passing on the condition.
