The multiverse may be bigger than we thought. The idea that we exist in just one of a massive collection of alternate universes has really captured the public imagination in the last decade. But now Hugh Everett’s 60-year-old “many worlds interpretation”, based on quantum mechanics, has been upgraded.

The northern white rhino is on the brink of extinction but we may be able to save it. Scientists plan to use frozen genes from 12 now dead rhinos to rebuild the entire subspecies. But how do you turn skin cells into actual rhinos and will it work?

A single-celled alga has done something thought to have happened just three times in the entire history of life on Earth. Braarudosphaera bigelowii has formed a unique bond with a bacterium living inside it and has developed a new cellular structure. This organelle may be why this alga became so successful and widespread.

We’ve got a new way of looking for aliens without having to go planet hopping. The method involves scouting the universe for planets that are close together and look similar to each other – hinting that an advanced civilisation may have colonised them.

We’ve had the orbits of the planets turned into music, we’ve heard the sonification of data and even heard what a black hole sounds like. This time, it’s the turn of mushrooms. Musician and artist Brian D’Souza has used a process called biosonification to produce musical tones from Shiitake and Reishi mushrooms. Learn more about Brian D’Souza here. And get details of his live performance on April 19th here.

Plus, we mark the passing this week of Peter Higgs, who first proposed the existence of the Higgs boson and later won the Nobel Prize for his efforts.
