Kangaroos Fart a Lot

Kangaroos are very windy. That is they fart a lot. Australian scientists have been in the field so to speak studying this. Climate change is the driving force for this study. The search to reduce greenhouse emissions from farm animals is also a driving factor.
Kangaroo eating grass fart windy farting methane gas
Unlike cows which produce large amounts of methane gas, kangaroos are relatively methane free. Kangaroos graze like cows. Indeed, if fresh grass is available their diet is much the same. It was thought that the mix of micro-organisms in their stomachs stops production of methane.

Western grey kangaroos and reds were kept in comfy Chambers where their ins-and-outs were studied. It was not the micro-organisms in the gut that reduced methane. Food passes through their digestion in a unique way. Unfortunately, just how this works has not been elaborated upon yet by scientists.

Organoid "Making" a Waste of Resources!

Scientists are creating tiny human organs from stem cells just for the sake of it. They hope that it will make for beneficial discoveries and applications in the future. Is it a waste of public and private money? It could be. There is an opportunity cost in using resources for wasteful projects.
Organoid brain
These tiny but useless mini-organs are called organoids. Indeed, Madeline Lancaster was messing-around" when she realized that she had grown a brain. Attempting to form embryonic stem cells from neural rosettes she accidentally succeeded. The floating milky substance floating in the culture was an embryonic brain - retina cells. A mass of different cells were found when the contents of the culture dish were closely analysed.

Organoids seem to mimic the operation of full-sized natural organs. Eye, stomach, gut, kidney, liver, pancreas, lung, prostate and breast mini-organs have been made. They do mimic some of the functions of the real thing. Unfortunately, they remain embryonic and do not keep growing to become actual copies human organs.

It seems organoids form on their own with no structural scaffolding required for them to make operational structures. Cell division simply follows the instruction written in the DNA. Their only use so far has been for testing of drugs and procedures to treat medical conditions. It is a developing science - early days.
