Seen through the Japanese module window: The newly installed solar arrays are rollin’ as they provide 45% more power than previously. We are using that power to perform science, manufacture pharmaceuticals, and pave the way to the moon and, eventually, Mars.

The better humans have gotten at making plastic, the more challenging it has been to unmake it—especially the pieces too small to see. Long after plastic bottles and bags break down, they keep fragmenting into particles so tiny, conventional filtration can’t touch them. They drift through treatment plants and into waterways unimpeded. There, they enter the food chain, and ultimately the body, where they have been found in human organs and are increasingly linked to various diseases such as cancer. Enter nanobots. In a new study, researchers show that tiny magnetic machines made of cagelike materials can tumble through water, sweeping up nanoplastics via the same electrostatic attraction that makes a balloon cling to your hair.

Not all signalling gradients are exponentials. Dicty cells (green nuclei) migrate towards their food source, bacteria (white), concentrating the signal (bacteria) at the front and redistributing it to the rear. Side view captured by Hugh Z Ford @chubblab using a 3i diSPIM.

If you ever feel like the gradients you're using are dull or muddy, try using OKLCH colors instead. In OKLCH, hue is angular, which means that the colors the gradient passes through are different compared to sRGB.

Babies don’t babble to sound cute—they’re taking their first steps on the path to learning language. A 2022 study shows parrot chicks do the same. Although the behavior has been seen in songbirds and two mammalian species, finding it in these birds is important, experts say, as they may provide the best nonhuman model for studying how we begin to learn language.
