Why the building blocks in our cells turned to the left
Amino acids could have become “left-handed” on a journey through space. Viviane Richter explains.
Ancient forest microbes live 2.5 kilometres under the sea
Scientists drilling off the coast of Japan have awoken an ancient creature from its long slumber. But don’t worry – they did not find Godzilla. They revived a community of microbes, trapped beneath the ground for around 20 million years.
Measuring the sixth mass extinction
How can we trust recent claims Earth is on the brink of a sixth mass extinction, when we can’t say with certainty how many species our planet has?
The lymphatic drain inside your brain
Has the human brain been hiding a dirty secret? While studying the membranes around a mouse brain, neuroscientist Antoine Louveau stumbled across something that wasn’t supposed to be there: a web of drainage channels called lymphatic vessels, the body’s waste disposal system.
A leap forward in the hunt for Earth-like planets
A new technique for studying distant worlds looks set to help scientists narrow the search.
Microbial gangs are organised killers
It turns out we have misunderstood bacteria. Rather than flying solo, their natural lifestyle is communal. And they can work together with devastating effect.
Crack addicts hooked on their environment
Around half of drug addicts relapse within a year of going “clean”. Research suggests we’d lower that figure if our crack clinics bore more of a resemblance to a drug den.
Some scientists are convinced more planets exist in our Solar System
Not many years ago, the idea our Solar System might contain undiscovered planets beyond Pluto would have been considered science fiction. But now, with NASA’s New Horizons spacecraft three months away from giving us our first close-up view of Pluto, astronomers are beginning to wonder. The more we study the dwarf planet and its surrounds, the less lonely it appears. Are there as-yet undiscovered worlds on the far edge of the Solar System?
