This Jellyfish Can Live Forever

Meet Turritopsis nutricula, the only known creature on this planet that is immortal.

From the Wikipedia article:

“It does this through the cell development process of transdifferentiation. Cell transdifferentiation is when the jellyfish “alters the differentiated state of the cell and transforms it into a new cell”. In this process the medusa of the immortal jellyfish is transformed into the polyps of a new polyp colony. First, the umbrella reverts itself and then the tentacles and mesoglea get resorbed. The reverted medusa then attaches itself to the substrate by the end that had been at the opposite end of the umbrella and starts giving rise to new polyps to form the new colony. Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal, although in nature, most Turritopsis, like other medusae, are likely to succumb to predation or disease…”

The Ottoman Empire Still Existed The Last Time The Chicago Cubs Won The World Series

Although the empire was in continuous decline throughout the 18th and 19th century, the monarchy wasn’t officially overthrown until November 1st 1922, after the Turkish National Movement won the Turkish War of Independence, and established a parliamentary state.

The Chicago Cubs last won the World Series in 1908.

What Happens to Bubbles in Space?

In the vacuum of space, a bubble wouldn’t be able to form due to the lack of exterior air pressure to counteract the pressure from within.

However, you can have fun with bubbles inside of a pressurized spaceship. Check out the video.

A Bubble Gets Its Color From Iridescence

As waves of light pass through the bubble, it gets distorted by reflecting off different layers of soap film.

You Can Freeze Bubbles

A bubble’s shell is composed of a layer of water molecules surrounded by two thin layers of soap. Technically, a bubble will freeze below 32 degrees Fahrenheit like all water.

The only problem is that bubbles tend to burst after a few seconds, so in order to see a bubble freeze, the temperature needs to fall to a temperature that will freeze water molecules more quickly.

Snapping Shrimp Kill Their Prey With Bubbles

Bubbles aren’t usually thought of as weapons, but that is exactly how the snapping shrimp uses them.

They create a cavitation bubble that immediately collapses creating a shock wave that, for a moment, is nearly as hot as the sun.

Why Do Bubbles Burst?

Anything that fractures the tenuous layer of water molecules can cause a bubble to burst. For example, a gust of wind or an object (like your finger) will easily cause a bubble to burst.

Also, a bubble will burst if enough of the water molecules evaporate.

Why Are Bubbles Round?

The liquid shell of a bubble is always pulling inward due to the phenomenon known as surface tension. The water molecules try to minimize the surface area of the bubble. A sphere is the shape with the least amount of surface area while containing volume.

When you blow a bubble, the surface area will minimize until the inward force of the surface tension equals the force of the air pressure within. If you blow in more air, you get a bigger bubble.

You Can Blow A Square Bubble

When two bubbles of equal volume join together, their connecting walls will become flat due to equal pressure from both sides.

By blowing a bubble in the middle of six other bubbles (2 vertical, 4 horizontal), the middle bubble will have equal pressure from six sides, creating a cube.

Alligator Vs. Python – Who Wins?

Both alligators and pythons are formidable predators, each with their own evolutionary strengths. With the recent explosion in the number of pythons in the Florida Everglades, there have been more and more encounters recorded between pythons and alligators. Merian: buy print With this in mind, I thought it would be interesting to see if one […]
