For 150 years, paleontologists assumed that the first vertebrates to leave the sea for land evolved a tadpole phase, similar to modern frogs. Immaculately-preserved fossils disprove that, scientists say.

Scientists analyzed over 900 marriages within the ’Ndrangheta, one of the most infamous mafia syndicates, to understand how “matrimonial ties relate to power and cohesion within the organization.”

“We really had no idea what we were getting ourselves into,” said one researcher involved in the first-of-its-kind study that dosed fish with psilocybin, the component in magic mushrooms.

Scientists analyzed thousands of self-reported dreams and discovered that our sleeping visions are influenced by personality traits and external events, such as the pandemic.

Humans can’t hear low-frequency “infrasound,” but a new study demonstrates that it raises our stress levels and triggers an “unsettling” feeling that could be linked to people’s experiences in haunted locations.
