Is the greatest existential threat our species has ever faced really something to joke about? Aaron Sachs thinks so. And, in fact, he thinks that, in many cases, we’re not joking about it enough.

We’ve long found different ways to explain that the world is made up of haves and have-nots. We live in the developed world or the developing world. There are those who are advantaged and those who are disadvantaged. And then, of course, there’s the one percent and everyone else. But under global warming, the climate journalist Jeff Goodell thinks, there may be a new way of describing this dichotomy: The cooled and the cooked.

For years, many people have assumed that climate change will send massive waves of “climate refugees” across borders around the world. But Jan Freihardt, a political scientist at ETH Zurich, says the reality is far more complicated. Studying communities along the Jamuna River in Bangladesh—where floods and erosion regularly destroy homes and farmland—Freihardt has followed families trying to decide whether to stay, move a little, or start over somewhere else. Distant migration is the option of last resort — and often not an option at all.

In 2011, an EF-5 tornado ripped through Joplin, Missouri, claiming 161 lives. Almost immediately researchers like Marc Levitan, from the National Institute of Standards and Technology, began working to understand why it was so devastating. The results of that investigation are now being implemented into building codes around the world. And the result is that we’re more ready for the next huge twister.

Historically, an “everyone is a VIP” philosophy made good business sense for Disney amusement parks. But now Disney is embracing tiered services. Daniel Currell explains why and what’s to come.

Again and again, similar patterns show up in nature in different creatures at different times in their evolutionary histories—even when those life forms have evolved on much different paths for hundreds of millions of years. And when they show up, as it turns out, we often perceive them as beautiful. So, the question is: Why?

Deep in the ocean, jellyfish, shrimp, fireworms and other creatures use multi–colored lights for defense, luring food, attracting mates, and communication. In their new book, Steven Haddock and Sönke Johnsen explore the nature of underwater light—investigating the varieties of transparency, pigmentation, iridescence, bioluminescence, and fluorescence found in the watery beyond.

The Trump administration is seeking an across-the-board 20% cut to NASA's total funding, and nearly all of that reduction is concentrated in science mission directorate.

Emerging research suggests that human attention spans are getting shorter. That’s a problem for people who want to make change in a world in which the issues we’re facing are growing ever more complicated. So now, perhaps more than ever, it’s important to understand the art and science of giving a good speech — and few people in Canada do that better than David Shepherd. But Shepherd says none of this came naturally to him.
