Those giant white hair looking things. Each one is a **single cell** bacteria. It is the largest bacteria known to man with each cell growing up to 2mm. You can see them with the naked eye and they are even strong enough to be picked up.

They are also unique as they are the only bacteria where the dna has a nucleus like membrane around it.

Interesting fact of the day: Most bee larvae, including honey bees, don't and can't poop until right before they spin their cocoon. Basically the upper and lower part of their intestine are seperate and there is no where for the poop to go. Right before they form their cocoon their intestinal tract connected, they poop their first and only poop as a larvae then spin their cocoon.

The reason for this is because all the food the larvae will eat is in the cell with them. As such if they were to poop it would contaminate the food. So by only pooping once, after the food is all eaten, it keeps the food safe and clean.

A friend of mine had remarked to this post out of channel saying:

> ADHD and autism have an even higher comorbidity rate, AFAIK, which is interesting

I find this an interesting follow up, so here is my response:

Sort of, in the case of ADHD its far more complicated... for starters the overwhelming majority of comorbidity is subclinical in this case (so doesn't typically count as true comorbidity). Moreover the comorbidity is unidirectional.

To put numbers to it (according to the best study I know of anyway):

* According to their interactions with parents and teachers comorbidity is only 3.2% and 2.6% respectively.

* For those with Autism about 1.2% of them have clinical ADHD while 31.4% are subclinical (their symptoms do not qualify for a ADHD diagnosis but they show some ADHD like properties)

* For those with ADHD about 4.1% of them have clinical Autism while 5.7% are subclinical.

So in reality the comorbidity is much much less between ADHD and Autism. I dont know off hand the comorbidity between BD and ADHD for subclinical but it likely is much higher than the numbers for Autism and ADHD

Hot take... Bipolar Disorder (as well as its milder cousin Cyclothymia) is just a subtype of ADHD, not its own separate disease. It is essentially where a person with ADHD cycles through ADHD-I (Inattentive subtype) and ADHD-HI (Hyperactive/Impulsive subtype). Essentially the ADHD-I is mistaken for the depressive phase and ADHD-HI is mistaken for the manic phase.

The various evidence supporting this:

* There is medical evidence suggesting a close genetic overlap between the two diseases.
* There is a very strong comorbidity with 20% of people with ADHD also having some form of BD
* The symptoms of each type closely resemble the characteristics of each pole of BD, so they are easily mistaken for eachother.

While its very unlikely (but very possible) my dream in life would be to witness a supernova.

Last time one was bright enough to see with the naked eye was about 400 years ago. So my chances are slim.

Interesting side note, a supernova is the fastest moving stellar event we can see with our naked eye that we know of. It starts and ends (usually resulting in a nebula) over the course of just weeks to months. Could you imagine seeing a bright light form in the sky out of nowhere, last for months, and then in the end have a beautiful new nebula in its place... my god that would be so cool!

Interesting fact of the day: The two largest fish known to us are in fact quite different in their maximum observed size.

The whale shark is generally considered the largest and their maximum size in tones is a little over 20 tons.

By comparison the basking shark is the second biggest but its max size only comes in at a little over 5 tones.

That would mean, by weight, the largest fish in the world is at its maximum 4x bigger thant he second biggest.

Interestingly, however, there isnt nearly as much disparity in their maximum length. The Whale Shark maxes out around 18 meters while the Basking Shark is around 14 meters.

Interesting fact of the day: Both dogs and wolves start to display object permanence at about the same time in their development (5b object permanence at ~11 weeks).

By comparison humans start to show stage 5b object permanence around 12 to 18 month.

Interesting fact of the day: Not counting point sources of light, any source of light that doesnt appear as a single point will have the same brightness no matter what distance you happen to be from it.

In fact the opposite is true in a sense. Once you get close enough to an object that you can no longer see the whole object within your field of view, then it will get **less** bright as you get closer.

Amazingly this even applies to the sun. IF you were at the surface of the sun, just a few feet away (Such that 1 meter square of the surface of the sun was within your field of vision) it would only appear to be 93 lumens bright. That would be equivalent to only a 6 watt incandescent light bulb! Compare that to the brightness of the sun from earth which is a whopping 127,000 lumens.

Interesting fact of the day: A fruit fly's sperm is many times longer than its body. In fact of all the animals it has the longest sperm relative to its body size.

A wonderful site showing a few different types of radio signal **refraction**. Important to note what you are seeing here is totally different from the effects you get from HF radio frequencies and occurs with VHF and UHF as well. Its why generally line-of-sight frequencies like UHF can sometimes go some ways over the horizon.
