Previous theories have cited microwave radiation from thunderclouds, oxidising aerosols, nuclear energy, dark matter, antimatter, and even black holes as possible causes, but scientist John Lowke dismisses […]

Jellyfish Quickest On The Draw?
Using a super-fast camera, researchers from the University of Heidelberg have captured the explosive discharge of tiny jellyfish stingers (nematocytes), revealing what could be the fastest cellular process in nature. Working with Hydra magnpapillata and Hydra oligactis, the researchers believe they are the first to quantify the kinetics and forces involved in the stinging action. […]
