There’s a Gatorade button attached to my basement fridge. If I push it, two days later a crate of the sports drink shows up at my door, thanks to Amazon. When these “Dash buttons” were first rumored in 2015, they seemed like a joke. Press a button to one-click detergent or energy bars? What even?, my colleague Adrienne LaFrance reasonably inquired. They weren’t a joke. Soon enough, Amazon was selling the buttons for a modest fee, the value of which would be applied to your first purchase. There were Dash buttons for Tide and Gatorade, Fiji Water and Lärabars, Trojan condoms and Kraft Mac & Cheese.

Mega-storms the size of England are increasingly savaging countries across the Sahel, a five-year project backed by the UK government has found. Already a troubled region, the Sahel – which hugs the Saharan desert from Senegal to Eritrea – has seen a threefold increase in mega-storms over the last 35 years. The ferocious storms – which produce roughly the same amount of energy in 12 hours that the entire UK consumes in a year – can devastate everything in their path with powerful winds and torrential rain. They can grow as high as 16km, satellite images show.

Uber is only gradually resuming its self-driving car program, but it's already thinking about expanding that technology to its two-wheeled services. The Telegraph has discovered that Uber is hiring for a "micromobility robotics" team that would bring "sensing and robotics technologies" to shared bikes and scooters.

Tens of thousands of Londoners died of cholera from the 1830s to the 1860s. The causes were simple: mass quantities of human waste and industrial contaminants were pouring into the Thames, the central waterway of a city at the center of a rapidly industrializing world. The river gave off an odor so rank that Queen Victoria once had to cancel a leisurely boat ride. By the summer of 1858, Parliament couldn’t hold hearings due to the overwhelming stench coming through the windows.

The boom in solar and wind power in the United States will deal a fresh blow to coal country in the next few years. Renewable energy, led by solar and wind, is projected to be the fastest-growing source of US electricity generation for at least the next two years, according to a report published Friday by the US Energy Department. Boosted by swiftly falling prices, utility-scale solar power is expected to increase by 10% in 2019 and 17% in 2020, the Energy Information Administration said. Wind power should grow 12% and 14% in those years, vaulting it ahead of hydropower for the first time.

When the rest of America is celebrating Martin Luther King Jr. Day on Monday, Alabama and Mississippi are observing a different holiday: Martin Luther King Jr./Robert E. Lee Day. And for a while, those states weren’t alone—Arkansas ended its joint holiday little more than a year ago. Bundling a holiday celebrating our nation’s most beloved civil rights leader with one for a man who fought to maintain slavery is one of the purest indications that our nation hasn’t truly reckoned with its history, so I talked to someone who is: lawyer, activist, and MacArthur “genius” Bryan Stevenson.

Microsoft CTO Kevin Scott believes understanding AI in the future will help people be better citizens. “I think to be a well-informed citizen in the 21st century, you need to know a little bit about this stuff [AI] because you want to be able to participate in the debates. You don’t want to be someone to whom AI is sort of this thing that happens to you. You want to be an active agent in the whole ecosystem,” he said.
