Historian Elizabeth Stordeur Pryor leads a thoughtful and history-backed examination of one of the most divisive words in the English language: the N-word. Drawing from personal experience, she explains how reflecting on our points of encounter with the word can help promote productive discussions and, ultimately, create a framework that reshapes education around the complicated history of racism in the US.

The only truly accurate map of the world would be a map the size of the world. So if you want a map to be useful, something you can hold in your hands, you have to start making choices. We have to choose what information we're interested in, and what we're throwing out. Those choices influence how the person reading the map views the world. But a map’s influence doesn’t end there, maps can actually *shape *the place they’re trying to represent and that’s where things get weird.

In much of the world, gender is viewed as binary: man or woman, each assigned characteristics and traits designated by biological sex. But that's not the case everywhere, says France Villarta.

Ask any deep space navigator like Jill Seubert what makes steering a spacecraft difficult, and they'll tell you it's all about the timing; a split-second can decide a mission's success or failure. So what do you do when a spacecraft is bad at telling time? You get it a clock -- an atomic clock, to be precise. Let Seubert whisk you away with the revolutionary potential of a future where you could receive stellar, GPS-like directions -- no matter where you are in the universe.

The weather can be a simple word or loaded with meaning depending on the context -- a humdrum subject of everyday small talk or a stark climactic reality full of existential associations with serious disasters. In his book The Weather Machine, author Andrew Blum discusses these extremes and much in between, taking readers back in time to early weather-predicting aspirations and forward with speculation about the future of forecasting, including potentially dark clouds on the horizon.

Nearly 1,800 newsrooms have shuttered across the US since 2004, leaving many communities unseen, unheard and in the dark.

"Full access to a person's phone is the next best thing to full access to a person's mind," says cybersecurity expert Eva Galperin. In an urgent talk, she describes the emerging danger of stalkerware -- software designed to spy on someone by gaining access to their devices without their knowledge -- and calls on antivirus companies to recognize these programs as malicious in order to discourage abusers and protect victims.
