The phenomenon, often called the "Returning Soldier Effect," refers to an observed increase in the proportion of male births during and immediately after major wars. This has been documented in several countries, particularly during and after World War I and World War II, with notable evidence from the United States, where the male-to-female birth ratio peaked in 1946. Typically, the baseline sex ratio at birth is about 105 boys per 100 girls, but during these periods, it can rise to around 108 boys per 100 girls.
The most unique eggs in the world. horn sharks lay eggs with a unique spiral or corkscrew shape. These egg cases, often called "mermaid's purses," have a tough, leathery texture and twisted flanges that help anchor them to rocks or kelp in the ocean. The shape protects the embryo and secures the egg in strong currents.
History Is Being Made! Organized by a startup called Sperm Racing, the event involves two sperm samples competing on a microscopic racetrack designed to mimic the human reproductive system, complete with chemical signals and fluid dynamics. High-resolution cameras will livestream the race, featuring stats, leaderboards, and play-by-play commentary for over 1,000 spectators. The startup raised $1 million to fund the event, which aims to raise awareness about declining male fertility rates—sperm counts have dropped over 50% globally since the 1970s due to factors like lifestyle, pollution, and chemical exposure. While the concept is humorous, the organizers emphasize its serious intent to encourage men to address reproductive health through lifestyle changes. Betting on the race, involving athletes or celebrities, is also planned to engage the audience.
