Neural networks overtake humans in Gran Turismo racing game p.213

Driving a racing car requires a tremendous amount of skill. Now, artificial intelligence has challenged the idea that this skill is exclusive to humans — and it might even change the way automated vehicles are designed.

A hard graft problem solved for key global food crops p.214

Grafting has long been used to join tissues of different plants in horticulture and research. Methods have now been devised to extend the technique to plants called monocotyledons, which include major crops such as cereals and bananas.

Electrons go loopy in a family of superconductors p.216

Measurements indicate that electrons move in loops between the atoms of an intriguing class of superconducting material. Such dynamics breaks key symmetries of the crystal lattice — suggesting the material hosts a rare state of matter.

Inflammation in the gut is encoded by neurons in the brain p.217

The nervous and immune systems interact in a bidirectional manner. It emerges that inflammation in the body activates brain cells that, when later reactivated, can trigger a recapitulation of the inflammatory response.
