To eliminate waste, we need to rediscover thrift | Andrew Dent

There's no such thing as throwing something away, says Andrew Dent -- when you toss a used food container, broken toy or old pair of socks into the trash, those things inevitably end up in ever-growing landfills. But we can get smarter about the way we make, and remake, our products. Dent shares exciting examples of thrift -- the idea of using and reusing what you need so you don't have to purchase anything new -- as well as advances in material science, like electronics made of nanocellulose and enzymes that can help make plastic infinitely recyclable.

A mouse with two dads — and a new frontier for biology | Katsuhiko Hayashi

You're familiar with the story: a sperm and an egg meet to create an embryo, which has the potential to give rise to new life. But what if you could create a sperm or egg from any cell, even a single skin cell? Biologist Katsuhiko Hayashi discusses the science of in vitro gametogenesis (IVG) — an experimental technique for creating lab-made sperm or eggs out of just about any type of cell — and explores its implications for endangered species, human reproduction and more.

Why spending smarter beats bigger budgets | Karthik Muralidharan

Billions of dollars are poured into global development every year, but results are lacking, says economist Karthik Muralidharan.
