Why do many problems in life seem to stubbornly stick around, no matter how hard people work to fix them? It turns out that a quirk in the way human brains process information means that when something becomes rare, we sometimes see it in more places than ever.
Thousands of people in Sweden have inserted microchips, which can function as contactless credit cards, key cards and even rail cards, into their bodies. Once the chip is underneath your skin, there is no longer any need to worry about misplacing a card or carrying a heavy wallet. But for many people, the idea of carrying a microchip in their body feels more dystopian than practical.
We’re increasingly aware of how plastic is polluting our environment. Much recent attention has focused on how microplastics – tiny pieces ranging from 5 millimetres down to 100 nanometres in diameter – are filling the seas and working their way into the creatures that live in them. That means these ocean microplastics are entering the food chain and, ultimately, our bodies.
