Scientists Successfully Implant Lungs into FishScientists have successfully created a goldfish that is capable of breathing atmospheric air. Using advanced microsurgery techniques, researchers at the New South Wales Veterinary Institute implanted a pair of frog lungs into the fish, which survived out of water for 2 hours.

The lungs were connected to the respiratory surface that were naturally found in the gills. The fish was able to conduct gas exchange through the lungs instead of the gills, which allowed it to breath in a terrestrial environment. A very humid chamber was constructed for the goldfish so that it did not dehydrate.

WHYIT’S ABOUTWHY NOT

i don’t think you guys understand how important this is if we’re able to put lungs in fish it means we may be able to put gills in humans which meanswe’re one step closer to becoming mermaidsI really hope these comments are sarcastic…

do they all just mate with the same man or something

obviously they reproduce asexually through mitosis

… Y’see, now, y’see, I’m looking at this, thinking, squares fit together better than circles, so, say, if you wanted a box of donuts, a full box, you could probably fit more square donuts in than circle donuts if the circumference of the circle touched the each of the corners of the square donut.

So you might end up with more donuts.

But then I also think… Does the square or round donut have a greater donut volume? Is the number of donuts better than the entire donut mass as a whole?

Hrm.

HRM.

A round donut with radius R

_{1}occupies the same space as a square donut with side 2R_{1}. If the center circle of a round donut has a radius R_{2}and the hole of a square donut has a side 2R_{2}, then the area of a round donut is πR_{1}^{2}- πr_{2}^{2}. The area of a square donut would be then 4R_{1}^{2}- 4R_{2}^{2}. This doesn’t say much, but in general and throwing numbers, a full box of square donuts has more donut per donut than a full box of round donuts.

The interesting thing is knowing exactly how much more donut per donut we have. Assuming first a small center hole (R_{2}= R_{1}/4) and replacing in the proper expressions, we have a 27,6% more donut in the square one (Round: 15πR_{1}^{2}/16 ≃ 2,94R_{1}^{2}, square: 15R_{1}^{2}/4 = 3,75R_{1}^{2}). Now, assuming a large center hole (R_{2}= 3R_{1}/4) we have a 27,7% more donut in the square one (Round: 7πR_{1}^{2}/16 ≃ 1,37R_{1}^{2}, square: 7R_{1}^{2}/4 = 1,75R_{1}^{2}). This tells us that, approximately, we’ll have a 27% bigger donut if it’s square than if it’s round.

tl;dr: Square donuts have a 27% more donut per donut in the same space as a round one.Thank you donut side of Tumblr.
