  • Can evolution go backwards?
    In 1893, Belgian paleontologist Louis Dollo suggested that evolution can’t go backwards in the exact same way that it proceeded. This became known as “Dollo’s Law,” and came under a lot of scrutiny. But, more recently, Dollo’s Law was co-opted into the idea that traits, once they gain a certain amount of complexity, can’t return to a simpler state. In this episode of Tiny Matters, we explore two exciting examples where scientists have found that not to be the case. Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

  • 'A cage of ovulating females': The development and testing of the oral birth control pill
    The 1940s were a pivotal time for the world. In the United States, as men went to fight in World War II, women became essential additions to the US workforce. And when the war ended, many of those women wanted to continue working. But having more children than they wanted or could care for was a huge barrier to making that a reality. When the oral birth control pill became available in 1960, it was a massive deal because it gave women control over when and if they wanted to have children. Today the pill is widely accepted, comes in a number of formulations, and is considered so safe that now you can buy it over the counter. But setting the groundwork for what we have available today took time, and experimentation. The history of the pill was also shaped by racism in an era where discrimination was not just state-sanctioned, but backed by many scientific institutions. In this episode of Tiny Matters, we cover the science and development of the oral birth control pill and, importantly, the lack of ethics in its testing, particularly in the trials that began in Puerto Rico in 1955.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

  • [BONUS] A hedgehog doppelgänger and STEVE lighting up the sky: Tiny Show and Tell Us #14
    In this episode of Tiny Show and Tell Us, we cover an aurora-like phenomenon — STEVE (Strong Thermal Emission Velocity Enhancement) — and how citizen science led to its discovery and unforgettable name. Then we talk about convergent evolution in tenrecs, a fascinating family of animals endemic to Madagascar. Some look identical to hedgehogs, some are similar to opossums, and others look like moles.
