Korea's "real-life mermaids"

South Koreans grew roughly 7 inches in a century on average

A hundred years ago, the average Korean woman was only 4’7”. Today, she stands nearly eight inches taller than her great-grandmother did, the largest jump of any country on earth. This video from Vox tries to explain why. Turns out, South Korea’s increasing postwar quality of life gave its people a (literal) leg up.

There is a nature preserve in Korea's DMZ

In almost every way, the Demilitarized Zone is a depressing place, a testament to humans' inability to make peace. There is one surprising upside: Keeping people away has allowed nature to thrive. Recently released images offer a 360-degree view of some of the hundreds of endangered species making a comeback in the DMZ, including white-naped cranes, mountain goats, musk deer, and golden eagles.

Underwater nighttime photos capture the ocean's diversity

Self-taught photographer Steven Kovacs explores Palm Beach's ocean after sunset, capturing tiny sea creatures in deep waters. Over eight years, he's dived into Florida's eastern coast, drifting from 0 to 100 feet, photographing rarely seen larval fish. Lacking formal marine biology training, Kovacs collaborates globally to identify species like cusk eels and the female blanket octopus, known for its revealing membrane. Check out his photos here.

An interactive of the deep sea

How specialized oxygen mixtures like heliox enable deep diving without feeling drunk

Beyond a depth of about 30 meters (98 feet), if divers are breathing surface air, which is about 78% nitrogen, underwater pressure forces more nitrogen into the bloodstream and induces nitrogen narcosis, whose symptoms resemble alcohol intoxication. Through saturation diving, where nitrogen is replaced with helium—an inert gas—deep divers can maintain cognitive function while working for extended periods.

Santa Barbara divers helped innovate deepwater diving technology

Divers in the Santa Barbara channel innovated a more efficient type of diving helmet in the 1960s that used helium to allow for longer, deeper excursions for oil surveying, abalone collecting, and more. These innovators have since set the standard worldwide for military and industrial diving.

In 1842, a 'mermaid' from Fiji was put on display at a museum, drawing large crowds and fooling many. It was later discovered that the creature was created by sewing the upper body of a monkey to the lower body of a fish.

Why South Korean women are having fewer babies

For decades, Asian countries have been combating dwindling birth rates by basically bribing families into having more children: offering government-subsidized housing, free IVF treatments, and even straight-up cash handouts. It hasn’t worked. In this BBC video, a TV producer, a cartoonist, and a private-school teacher explain their views on having children in 21st-century Korea.

South Korea has the lowest fertility rate in the world

If current birthing trends persist, every hundred South Koreans today will have only six great-grandchildren between them. This crisis is a result of high expenses, harsh work-family trade-offs for women, declining marriage rates, and other societal factors. Some newer policies are helping to build incentives for having children, but larger issues also need to be addressed.

Why no aquarium has a great white shark

Historically, great white sharks die very quickly in captivity—with the exception of the Monterey Bay Aquarium's successful attempt in 2004. The aquarium held a four-year-old great white for six months. Before that, the longest stint was 16 days. The creatures can only breathe if they are moving forward, making survival difficult in a small tank.
