Today you learn why Australia has bubblegum pink lakes, why immortality is mathematically impossible, and how often you should

wash your sheets, towels, and basically everything you own.

Let's clean up and satisfy some curiosity.

Recent research may have uncovered the reason why Australia has lakes that are bubblegum pink.

Yeah, you heard that right.

Now they don't taste like bubblegum, unfortunately,

but Australia does in fact have lakes that have a vivid pink color.

The most famous of these lakes is probably Lake Hillier, which is located off the southern coast of Western Australia on Middle Island.

In the past, people speculated that the color could be due to high salt content or

micro algae.

But here's something you might have missed. In 2015, a team of researchers from the Extreme

Microbiome Project decided to investigate the exact cause of this pink anomaly.

They collected water samples, then performed DNA analyses on what they found,

and they found 10 species of salt-loving bacteria and several species of algae that were some shade of pink or red. And get this, a single

species of bacterium called Salinobacter ruber was responsible for 33% of

the DNA collected. Scientists suspect that this bacteria is the most likely source of the pink color, not micro algae.

Looks like mother nature can't trick us for too long.

Despite bacteria being the reason for the strawberry milk color,

Lake Hillier is totally safe to swim in.
