A once-independent bacterium has evolved into an organelle that provides nitrogen to algal cells – an event so rare that there are only three other known cases

About 1.5 billion people worldwide carry a risk of conditions including malnutrition because of parasitic infection, and AI could help identify those affected

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

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

A small early-stage trial of the approach, which involves testing dozens of drug combinations on thousands of dishes of cells, may help people with cancer live for longer

Ground-level ozone, a product of pollution from cars, degrades insect pheromones, and this can result in mismatched mating and sterile offspring

We don’t know what alien life might look like, but if other civilisations can colonise multiple worlds, we might see planets that look unusually similar

These soccer-playing robots can respond faster than ones trained in a standard way because they improved their skills via an artificial intelligence-based technique called deep reinforcement learning

Our favourite sad songs seem to become less enjoyable when we try to take the emotion out of them

The skin microbiome may be a bigger cause of post-operative wound infections than bacteria contaminating hospital equipment

Research-level mathematics might seem an unlikely proving ground for artificial intelligence, but recent developments suggest it offers a route to automated human-like reasoning

My column about the spiritual side of science has seen many of you sharing your own awe-inspiring experiences, says David Robson

The prolific Adrian Tchaikovsky has two terrific sci-fi offerings out this year, one the story of a scientist turned prisoner shipped to a faraway planet, the other a light-hearted tale of robotic murder, says Emily H. Wilson

Since 2012, Mary Jo Hoffman has taken one snap a day of the natural objects around her. She explains what lies behind two of them - and what the "art of noticing" has brought to her life

From the Book of Revelation to extinction fiction, we just love end times. A new guide by Dorian Lynskey is full of gems

Inequality is a major obstacle to sustainability. The super-rich are an environmental horror story that we can't ignore, says Graham Lawton

Feedback finds that despite close investigation, more research is needed to "better quantify tail wagging in general"

Nutrition must be as essential as maths or science at our educational institutions to solve the US obesity crisis, says Aman Majmudar

It's tough turning neuroimmunology into a gripping read, but Monty Lyman's excellent book provides a delightful overview of the connection between the brain, immune system and gut microbiome

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
