Feedback isn't sure what to make of a ground-breaking piece of research into the understudied topic of "subjective individual variability in onion tearing and its relationship to chemosensory sensitivity"

The first six months of the year have brought us popular science reads on everything from consciousness to cosmology. Liz Else rounds up her favourites

The company has been touting its quantum technology for years, but some experts say these claims just don’t pass muster

We’ve known for a long time that there are organic molecules on Mars. Rovers and landers keep turning them up wherever they look. But, “organic” simply means a molecule is made up of carbon and hydrogen atoms, not that it was created by life - there are plenty of non-biological processes that can create organic molecules. But there is one feature of organic molecules that can point very strongly in the direction of life or not - its chirality, and a new instrument on the Rosalind Franklin rover, planned for launch to Mars in the 2030s, just proved it can successfully look for it.
