But it does get the job done. Specifically, this is the call of the horny male koala—and this sound is such an effective mating technique that simply hearing it can cause female koalas to go into heat. (Insert your own Koala Justin Bieber joke here.) Scienceline explains the importance of koala "bellowing":
The timbre of a koala's bellow seems to have something to do with its size, age and androgen (a sex hormone) concentration. Older males bellow more, bigger males bellow longer, and those with more androgen have deeper bellows. One study found that when the male koala is 2-4 years older than the female, the mating is more likely to be successful, leading some to suggest that females use male calls to gage their relative sexiness.
At Blue Hill, Maine’s George Stevens Academy, there lies a Twinkie that was the subject of teacher Roger Bennatti’s 1976 science lesson on chemical preservatives and shelf life.

In the early 1970s, Princeton University physicist Gerard O’Neill became a space activist touting plans to build human colonies in outer space. He argued that humans could escape (while helping alleviate) the environmental damage we are causing on Earth by migrating to space habitats housed in cylinders that would be suspended 250,000 miles from Earth […]
In a new scientific study, McGill University researcher Jay Olson combined stage magic with psychology to make people think that an fMRI machine (actually a fake) could read their minds and implant thoughts in their heads. Essentially, Olson and his colleagues used “mentalist” gimmicks to do the ESP and “thought insertion” but convinced the subjects […]
