Diets that claim to control excess oestrogen or stress hormones are all the rage on Instagram and TikTok. They could be good for us, just not for the reasons claimed

Most ingredients touted as the key to better health fail to live up to the hype but fibre bucks this trend, with benefits for the whole body, not just the gut

The health benefits of fermented food and drink have long been touted, but firm evidence in favour of kombucha, sauerkraut and kefir is surprisingly elusive

Claudia de Rham has spent much of her life dedicated to unravelling the true nature of gravity, thinking deeply about gravitons, the hypothetical carrier of this enigmatic force

A super-stretchy hydrogel can stretch to 15 times its original length and return to its initial shape, and could be used to make soft inflatable robots

The physicist Peter Higgs quietly revolutionised quantum field theory, then lived long enough to see the discovery of the Higgs boson he theorised. Despite receiving a Nobel prize, he remained in some ways as elusive as the particle that shares his name

We can’t stir ordinary solids, but one research team now claims to have stirred an extraordinary quantum “supersolid”, generating tiny vortices

To capture the clearest and most direct images of a “Wigner crystal”, a structure made entirely of electrons, researchers used a special kind of microscope and two pieces of graphene unusually free of imperfections

Researchers have used quantum light to create a magnetic field with a strength that is measured in imaginary numbers

In the 1920s, Erwin Schrödinger wrote an equation that predicts how particles-turned-waves should behave. Now, researchers are perfectly recreating those predictions in the lab

The Large Hadron Collider is testing entanglement in a whole new energy range, probing the meaning of quantum theory – and the possibility that an even stranger reality lies beneath

Concern over the risks of enabling nuclear weapons development is usually focused on nuclear fission reactors, but the potential harm from more advanced fusion reactors has been underappreciated

A practical superconductor would transform the efficiency of electronics. After decades of hunting, several key breakthroughs are inching us very close to this coveted prize
