Previous research has shown that a gorilla's larger body size is linked to reproductive success and social rank. The chest-beating could be another way for the gorillas to convey their size to others and, in turn, avoid fights that could result in serious injury or death.

Gorillas Beat Their Chests to Communicate With Each Other

The larger male apes have lower frequencies in their pounds and may use chest-beating to signal their social status, strength, and size to others

During the dive mission, the divers found and captured footage of the ship's bridge, midsection, and bow that had hull number "557" still visible on both sides.

The surges in twin births occurred only in fraternal twins and may be from increased use in vitro fertilization methods.

Twin Birth Rates Have Soared Globally in the Last Three Decades

The trend is a result of women deciding to have children later in life and the use of medically assisted reproduction methods

For decades there were rumors of leaking barrels filled with the pesticide DDT littering the ocean floor off the coast of Santa Catalina Island dumped by the now-defunct, Montrose Chemical Corp, the largest global DDT manufacturer based in Los Angeles
