The Axolotl - A Regenerating Salamander

The axolotl is a Mexican salamander with remarkable regenerative properties. As Wikipedia says:

The feature of the salamander that attracts most attention is its healing ability: the axolotl does not heal by scarring and is capable of the regeneration of entire lost appendages in a period of months, and, in certain cases, more vital structures. Some have indeed been found restoring the less vital parts of their brains. They can also readily accept transplants from other individuals, including eyes and parts of the brain—restoring these alien organs to full functionality. In some cases, axolotls have been known to repair a damaged limb as well as regenerating an additional one, ending up with an extra appendage that makes them attractive to pet owners as a novelty. In metamorphosed individuals, however, the ability to regenerate is greatly diminished. The axolotl is therefore used as a model for the development of limbs in vertebrates.

Here's a video with more information on the axolotl and its regenerative abilities:

It's debatable whether the researcher's "five-star hotel" claims are legitimate, but it's an interesting video nonetheless. And if you'd rather spend your Friday looking at baby animals, check out this video of a baby albino axolotl or this video of a colorful adult.

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.

This First-Grade Math Problem Is Stumping the Internet

If you’ve ever fantasized about how much easier life would be if you could go back to elementary school, this math problem may give you second thoughts. The question first appeared on a web forum, Mashable reports, and after recently resurfacing, it’s been perplexing adults across social media.

According to the original poster AlmondShell, the bonus question was given to primary one, or first grade students, in Singapore. It instructs readers to “study the number pattern” and “fill in the missing numbers.” The puzzle, which comprises five numbers and four empty circles waiting to be filled in, comes with no further explanation.

Some forum members commented with their best guesses, while others expressed disbelief that this was a question on a kid’s exam. Commenter karrotguy illustrates one possible answer: Instead of looking for complex math equations, they saw that the figure in the middle circle (three) equals the amount of double-digit numbers in the surrounding quadrants (18, 10, 12). They filled out the puzzle accordingly.

A similar problem can be found on the blog of math enthusiast G.R. Burgin. His solution, which uses simple algebra, gets a little more complicated.

The math tests given to 6- and 7-year-olds in other parts of the world aren’t much easier. If your brain isn’t too worn out after the last one, check out this maddening problem involving trains assigned to students in the UK.
