2018 Year in Physics Review Part 1: We begin our countdown of the top physics stories of the year, as chosen by Ian Durham.

Superhuman: In this special edition, evolutionary biologist Rowan Hooper discusses his new book, which examines the extremes of mental and physical ability. He discusses encounters with some of the world's cleverest people, investigates the role of genetics in intelligence, memory, drive and focus, and describes people whose immense resilience has seen them come through terrible adversity. Hooper also describes lessons we can take from human evolution when programming AI.

High-energy neutrino traced back to a distant galaxy, with Azadeh Keivani; possible discovery of sterile neutrinos, with Richard Van de Water; black holes replaced by fuzzballs, with Samir Mathur; finding an almost-quantum theory, with Miguel Navascues; and testing free will with AI, with Avi Loeb.

Losing the Nobel Prize: In this special edition, physicist Brian Keating discusses his new book, which recounts the ill-fated BICEP2 announcement--and retraction--of the claimed discovery of primordial gravitational waves in 2014.
