What Trees Are Made of

Almost all of a tree's mass comes from the air. The tree will take carbon dioxide from the air and water; it will use solar energy to split the water molecules and combine them to the carbon atoms freed from the carbon dioxide and release the oxygen as a waste product. 
The root of a tree doesn't use anything in the soil except some nitrate compounds but they are almost nothing. Using air water and sunlight, a tree self assembles into a giant wooden structure that towers over all the animals.

AI Cribbage

If you ask chat GPT to play Cribbage with you, it will cooperate and set up a virtual game of Cribbage. 

It will start dealing text based playing cards and hide its own hand and ask you what cards you want to remove. It will even do all the pegging for you virtually. 
The same is true of snakes and ladders. It will create a text based version of the game with a virtual dice and place ladders and snakes at different  points on the board.

Dehumidifier Credit

If you buy a good Dehumidifier that can remove more than 12 liters of Water per day, it will pay for itself in less than a year. During winter months it will reduce your heating bill because dry air is better at storing heat than damp air and feels warmer so you feel compelled to turn down your thermostat. 
It could also reduce the amount of time your sick from off work because dry air carries less microbes and viruses. 

It can also stop damage to walls and furniture cased by condensation.

Chromosome 2

In humans, Chromosome 2 is actually two chromosomes fuzed together. Most chromosomes are X shaped but they're only like that when the cell is about to split into two. Normally they are just a single thread of DNA. For some reason we have one Chromosome that is two fused together. 

There are telomere sequences in the middle of the Chromosome, they usually appear at the ends of the Chromosome.

Bombadier Beetle

The Bombadier Beetle has a biological weapon, their backside doubles as a gun. They can shoot burning hot acid out of their backsides to give predictors burns and put them off hunting them. 


The Bombadier Beetle does this by mixing Hydrogen Peroxide and Hydroquinone together in a chamber inside their abdomen. The two chemicals are present in separate glands in their abdomen but when they're mixed together they become a hot explosive acid.

Train Vs Taxi

If you were going from farringdon in London to Brighton, what is better? Uber or Train. 
If four adults were travelling together, the prices would be about the same. 
~image generated by artificial intelligence (chatGPT)

A taxi going from London to Brighton costs roughly £100 (£25 each). 
A train ticket for 4 passengers going from London to Farringdon would cost about £100 (£25 for each passenger) 
If you had fewer passengers, the taxi would still cost £100. It would only be the same price and slightly more convenient if you were going as a small group. 

This observation doesn't account for rail cards and discount codes. 

Trains move a lot faster than cars and they sometimes give you cheaper return tickets, however some Uber cars can take more than 4 passengers, some can take 6 or 7.
