While many animals become less fertile as they age, only three species—humans, pilot whales, and killer whales—have females that regularly live well beyond their reproductive prime. These are the only species where we see grandmas acting like grandmas: they've long stopped producing offspring of their own, so they pivot to helping care for their children's children.
We like to think that human speech is special. It defines our species and separates us from those animals that we'd rather think of as inferior. The trouble is that it's difficult to know when and how human speech arose because “language expressed via speech leaves no fossils behind.”
California is usually drenched with sunlight. But this week, it's just drenched. A series of storms have pummeled the state, dropping staggering quantities of rain and snow—leading to flooding, mudslides, and a whole lot of water pouring into reservoirs that were just about dried out.

I'm three and half years into a lifelong diet. It's not to lose weight or build muscle, and there are no cheat days—no, not even for a freshly-baked chocolate croissant that I can smell a block away. I get a metal probe put down my throat every year so my doctor can confirm that I'm really, truly, 100 percent adhering to my diet. As if that wasn't awesome enough, I also get to pay anywhere from 30-500 percent more for basic food.
