Research explores how female astronauts handle menstrual periods in space.
Gender of many reptiles, including crocodilians and turtles, is largely determined by the temperature in which eggs incubate. When taking a closer look at the molecular mechanisms behind this phenomena known as temperature-dependent sex determination, researchers discovered a thermosentive protein inside the egg plays a key role.
Warmer climates are yielding more female hatchlings, researchers explain in a new study. This could have serious impacts on the survival of struggling loggerhead sea turtle populations in Florida.
Yale researchers discovered more female green frogs are being born in suburban ponds. They recently linked this unbalanced sex ratio to common lawn plants, such as clover.
Stegosaurus were known for their spiked tails and armor-like exterior, and new research shows that their iconic bony plates may have determined the sex of these dinosaurs, according to new research.
Using a certain type of "transgender" green algae, scientists have discovered the genetic origin of male and female sexes, showing how they evolved from a more primitive mating system into a single-celled relative.
There is a reason that hurricanes Sandy, Irene and Katrina are in the history books as some of the most deadly and destructive: they are named after women. According to new research from the University of Illinois, hurricanes with feminine names are likely to be more deadly than their masculine counterparts, apparently because female-named storms are perceived as less threatening.
