It’s a question psychologists have been wrestling with for decades: What exactly is time?Not the time kept by clocks or calendars, but the time we actually experience. Why do some moments stretch and others collapse?Martin Wiener has spent much of his career trying to understand those questions. His work suggests that our experience of time is not fixed at all. Instead, it may be something the brain continuously constructs and reshapes according to the information it decides is worth remembering.

If one of the most important roles of science fiction is that it makes unfamiliar ideas emotionally legible, what are the ideas that we need to be reading about right now?

There is no denying it: A.I. has changed higher education, and teachers are trying to catch up — to figure out how to live in this new world, and how to make learning meaningful.Stephen Aguilar studies how emerging technologies shape teaching, learning, and motivation. He’s also co-leading work at the USC center for generative A.I. and society, which just released a new report examining how students and teachers are actually using artificial intelligence in real classrooms.

Scott Simon has spent a lifetime telling other people’s stories on national public radio. But every now and then, along the way, he’s found reasons to tell the stories of the animals with whom we share this world, and he’s collected those stories, and more, in his latest book.

In workplaces everywhere, the most engaged employees often become the go-to for extra work. It feels logical, but management scholar Sangah Bae believes that instinct might be backfiring — a lot. Her recent work shows that intrinsically motivated workers are disproportionately assigned additional tasks, often at a cost to their performance, satisfaction, and long-term retention. The reason isn’t just that they’re capable—it’s that managers assume they’ll actually enjoy the extra work.

A geologist, a planetary scientist, a NASA mission leader, and an expert on team-building walk into a bar. The bartender says, “hey, Lindy, are you drinking alone today?” In this episode, we talk about what it takes to be a polymath, and why it can be such a joy.

For decades, the case against industrial animal farming has been framed as a moral one—and it hasn’t slowed consumption. As countries grow wealthier, meat consumption rises right along with them. But according to Bruce Friedrich, a different kind of change is now underway. From plant-based meat to cultivated proteins, a technological shift may be emerging—one that could make animal farming obsolete, not because people changed their minds, but because the system changed around them.

This winter’s snow drought may leave a mark that lasts for centuries. Justin DeRose, a dendrochronologist and assistant professor of silviculture and applied forest ecology at Utah State University, says trees across the West are already recording the story of climate in their rings — wet years, dry years, fire years, and sometimes years so harsh they leave almost no growth at all. And as drought years begin stacking up closer and closer together, those forests may be telling us something important about how fast the West is changing.

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 a very long time it was thought that some alcohol, in moderation, could be healthy for us. The latest research suggests that’s simply not true. This certainly doesn’t mean people shouldn’t be allowed to drink — but we should at least know why we drink as much as we do. And that’s a question that Dr. Charles Knowles has tried to resolve in his new book.
