Did you know that an "immortal jellyfish" exists? That strange creature will use a rare cellular mechanism called "transdifferentiation" to respawn as a new polyp clone colony :)

Do they survive vaccum space and it is quite interesting to see this in humans in the future

They do not survive the vacuum of space nor diseases and will still die when eaten or on land.
Turritopsis dohrnii, as the jellyfish is known as, is only biologically immortal, meaning it wont die of old age or injuries that dont kill you outright. Once the jellyfish grows old, or gets injured, it will revert to a colonial stage from with it spouts ephyra's (baby jellyfish).
Technically speaking the new jellyfish are kinda identical clones to the original rather that the same individual, but that is due it strange life cycle of jellyfish.

The thing that makes this jellyfish interesting is that they are the only known species that can re-specialize mature cells.
For example when a un-specialized cell or ours matures and become, let's say, a skin-cell, it will always be a skin-cell, it can never be anything else. Even the divisions of that skin-cell can never be anything but a skin-cell.
This immortal jellyfish can re-specialize it cells, allowing it to go back to a polyp stage.

The ones which survive in vacuum and in space are water bears (tardigrades). You can freeze them, unfreeze and they resurrect. You can put them in vacuum and they die, put them in water or moist air and resurrect. They also survive extremely high pressures.

Talking about pressures, there's a mouse with a skeleton configuration that (alive) can resist being stepped on by an elephant. The skeleton will remain unbroken, but I forgot the name of the mouse.

The most potent smelling substance (or worst smelling in other words) is Thioacetone. There's not much info about it because it doesn't have any use so far and it's so awful to work with that no one rushes to experiment with it. You'll be able to smell a drop of it instantly, even at a few hundred meters away. It induces nausea and vomiting and it has been described as "fearful".
Taken straight from the wikipedia page:

"In 1889, an attempt to distill the chemical in the German city of Freiburg was followed by cases of vomiting, nausea and unconsciousness in an area with a radius of 0.75 kilometers around the laboratory due to the smell."
"In 1967, Esso researchers repeated the experiment of cracking trithioacetone, at a laboratory south of Oxford, UK. They reported their experience as follows:
Recently we found ourselves with an odour problem beyond our worst expectations. During early experiments, a stopper jumped from a bottle of residues, and, although replaced at once, resulted in an immediate complaint of nausea and sickness from colleagues working in a building two hundred yards [180 m] away. Two of our chemists who had done no more than investigate the cracking of minute amounts of trithioacetone found themselves the object of hostile stares in a restaurant and suffered the humiliation of having a waitress spray the area around them with a deodorant. The odours defied the expected effects of dilution since workers in the laboratory did not find the odours intolerable ... and genuinely denied responsibility since they were working in closed systems. To convince them otherwise, they were dispersed with other observers around the laboratory, at distances up to a quarter of a mile [0.40 km], and one drop of either acetone gem-dithiol or the mother liquors from crude trithioacetone crystallisations were placed on a watch glass in a fume cupboard. The odour was detected downwind in seconds"

Interesting, at least it's rare and hard to come by, there's also a plant in Australia that's quite common and very normal looking, but will inflict insane pain if you touch it. It led people to commit suicide just to escape the suffering from it cause in many cases the pain lasts months. It's name really doesn't make it justice, the Gympie-Gympie.

There is a "sound channel" about 1,000 meters deep in the ocean where sounds will carry much farther than any other depth. It is often used for long-distance communication!

Unfortunately scientists were unable to replicate reliably in lab the results of "Mpemba effect" that were not within margin of error.

It's a cool thing you can do with hot water on a cold winter day. There is however no proof pointing towards the cause of this experiment being different innate freezing times between hotter and colder water.

I believe the common explanation of the observed effect is that when taking into account two bodies of water of the same mass some portion of the hot water will evaporate, leaving smaller number of water particles that needed to freeze.

Sound cannot go louder than 194 db (on Earth, with normal air conditions), as past that limit air cannot move anymore. A blast of sound at this theoretical volume would wreck unprecedented havoc the likes of which is really hard to imagine.

For comparison, the loudest sound ever recorded was a volcano eruption in 1883. It produced an insanely loud bang, mesured at 174db approximately 160km from the site.The sound was so loud that it produced four times more power than the Tsar Bomba. People living nearly 5000km from the site heard it as if it was a nearby cannon. People got ear injuries hundreds of miles away.

If like me you think this is fascinating, this video is where I learnt about this and it was, indeed, a fascinating watch.

Regarding the 174db vs 194db difference - a 10db increase is a 10-fold increase in energy, which means the maximum energy released would be 100 times stronger than Krakatoa's eruption. Or 400 Tzar bombs.

didn't know about this but after some little research
this was discovered in 2009 and it says that one of the molecules they identified, ethyl formate, smells like raspberries and rum.
also in 2020 a team of scientists confirmed that there's a supermassive black hole that lurked at the center of the Milky Way and they got the nobel prize. and if there's a black hole in the center of our galaxy there's no way that there's smell.
So your fact is not that accurate

Actually both are accurate.

If humidity gets too high, relatively low heat can kill humans. The equivalent of 95ยฐF/35ยฐC at 100% relative humidity can kill even healthy humans. This is called a Wet Bulb Event. It happens since Humans rely on evaporating sweat to stay cool. Makes me wonder the temps here go all the way up to 40 with humidity around 70% should I be worried?

This isn't so obscure, but it is so surprising (and so hard to believe!) that it deserves mention: The Banach-Tarski "paradox".

It says that it is possible to separate a solid ball in exactly five disjoint pieces, and then recombine the pieces (just by moving the pieces, without changing their shape at all) to form exactly two solid balls of the same size as the original one.

Here is the Wikipedia article on it, and a nice Vsauce video actually gives the proof.

By the way, it is not really a paradox, it is just very very very very counter intuitive. Bottom line, there are no laws of Nature or Math that forbid this operation (well, ok, the Axiom of Choice is used in the proof)... It is just that the pieces have no definable "volume".

Some theorize that the orange colors predominant in the sky in Edvard Munch's The Scream are the result of increased Mie Scatter, a result of the large concentration of aerosols resulting from the eruption of Krakatoa Volcano. This volcano erupted on August 23, 1883 (I think it actually exploded) and The Scream was painted in the year 1893. Aerosols, a result of the volcanic eruption, are suspended in the sky for many years after the eruption.

Rain doesnโ€™t always make the ground wet.

In dry, hot places, rain sometimes evaporates before it hits the ground. Environmentalist Edward Abbey describes โ€œphantom rainโ€ this way: โ€œYou see curtains of rain dangling in the sky while the living things wither below for want of water. Torture by tantalizing, hope without fulfillment. Then the clouds dissipate into nothingness.โ€
