Editorial
How to succeed at failure Two hikers encounter a hungry bear in the woods, the old joke goes. The bear clearly means business, which prompts one hiker to turn to run away. The other hiker, drawing upon conventional wisdom, reminds his departing companion that running is futile. No one can outrun a bear. Without pausing a step, the fleeing hiker responds, “I don’t need to outrun the bear, I just need to outrun you.” The...

Lighter Side
How perovskite solar cells could benefit from a makeover Perovskites and the mullet hairstyle have more in common than one might think. Both have traditionally attempted a vexing blend of practicality and capriciousness and, perhaps as a consequence, both have struggled to gain their place in the sun. Now that these parallels have been highlighted, they may seem obvious in retrospect. But it took a group of researchers at the Queensland University of...
