In today’s newsletter, we report the world’s population hitting a dizzying new milestone, solve a mystery about a California island castaway who captured a nation’s imagination … and try a diet that may help you live longer. Plus, a photo quiz about a particularly homely fish—and a list of extraordinary veterans remembered by our readers.

In just a dozen years, the Earth has added a billion people, putting us at the cusp of 8 billion—and demographers say we’re headed toward 9 or even 10 billion.

The growth is happening as two parts of the world going in different directions, with baby booms in Nigeria and a sharp decline in China (which will soon be surpassed by India, pictured above, as the world’s most populous nation).

So far, our world, 7 billion people more numerous than in 1804, has handled the growth. But for how much longer?

The ‘Lone Woman’: When otter hunters found the striking, silent, nameless woman (illustrated above) alone on a remote California island, the mystery captured a nation. It led to Island of the Blue Dolphins, a tale read by generations of American kids. Turns out, much of what we knew was wrong.

Why do people lie? And why do we believe liars? Lying is a natural stage in child development, and kids become more sophisticated in their lies as they age, Nat Geo reports. (Pictured above, researchers testing a 9-year-old girl with functional near-infrared spectroscopy technology.)
