Mystery Solved: Scientists Have Finally Figured Out Why Urine Is Yellow

Why exactly is urine yellow? Researchers finally have the answer to a question that stumped them (and many other humans) for years. In a study published this week, scientists with the University of Maryland and the National Institutes of Health identified the enzyme responsible for urine’s color.

It’s remarkable that an everyday biological phenomenon went unexplained for so long, and our team is excited to be able to explain it,” lead author Brantley Hall, an assistant professor in UM’s Department of Cell Biology and Molecular Genetics, said in a news release from the university.

It’s long been known that the molecule urobilin is linked to the yellow hue, but its source remained a mystery. The team found that as red blood cells break down, a bright orange pigment called bilirubin is produced. “Gut microbes encode the enzyme bilirubin reductase that converts bilirubin into a colorless byproduct called urobilinogen,” explained Hall. “Urobilinogen then spontaneously degrades into a molecule called urobilin, which is responsible for the yellow color we are all familiar with.”

The findings could have significant implications for understanding gut health, inflammatory bowel disease, and other ailments. “Now that we’ve identified this enzyme, we can start investigating how the bacteria in our gut impact circulating bilirubin levels and related health conditions like jaundice,” said study co-author Xiaofang Jiang. “This discovery lays the foundation for understanding the gut-liver axis.”

Inside the Quest to Preserve Quiet Places in an Increasingly Noisy World

Phone alerts, car horns, and road noise are such a common part of our hustle-and-bustle world that it’s easy to forget what natural silence sounds like, let alone be able to find it. But there’s a growing movement to preserve spaces of silence and nourish those with a thirst for quiet escapes.

Meet Quiet Parks International: a nonprofit committed to “saving quiet for the benefit of all life.” The team includes scientists and acoustic ecologists dedicated to identifying, understanding, and preserving places where you can experience at least 15 minutes of natural silence — or in other words, no human-made noise.

Although quiet is defined as a lack of noise, it is so much more than that, according to Matthew Mikkelsen, a sound recordist and executive director of Wilderness Quiet Parks. “Quiet, I think, holds space for things that we can’t verbalize as humans,” he told CBS News. “We use silence as a way to honor things.”

Quiet locations — which include national parks and nature reserves — are becoming increasingly rare, making them all the more necessary to protect and savor. Said Mikkelsen: “I know people find a lot more than just a good, enjoyable listening experience when they go to a quiet park. They find things that stay with them and that help them live more happy, fulfilled lives.

How Stray Cats Are Teaching Chilean Inmates More Responsibility and Compassion

We all probably agree: There’s a lot that can be learned from our pets. This is especially true for inmates at the largest and oldest penitentiary in Chile, where stray cats are showing the human residents how to become more compassionate versions of themselves.

“They’re our companions,” Carlos Nuñez told The New York Times. Nuñez, who is serving a 14-year sentence, has developed a strong bond with a tabby he named Feita, meaning “ugly” in English.

The 180-year-old prison houses 5,600 inmates and roughly 300 stray cats. Initially, the felines were credited with simply helping with a rat problem. But over the years, they’ve offered much more, according to inmates and staff. Col. Helen Leal González, the prison’s warden, explained that the presence of the cats “has changed the inmates’ mood, has regulated their behavior, and has strengthened their sense of responsibility with their duties, especially caring for animals.”

This relationship is a two-way street. The cats get shelter, food, and care; the inmates get lessons in how to accept and reciprocate love. “A cat makes you worry about it, feed it, take care of it, give it special attention,” Nuñez explained to the Times. “When we were outside and free, we never did this. We discovered it in here.”
