Microscopy Treasure Hunt

In the slide is a microscopy of Alium cepa roots (Onion). We looked at it for a scientific stream with optical miscope.

Since we are close to the RAM (Root Apical Meristem) the cells are small, since they're newborns. The dark spot in the middle is the nucleus, containing the chromosomes (they're called like this because they absorb dye really well, and they become easily visible, the words come from the Ancient Greek and means colored bodies), most of them are in the Chromatin form: they're relaxed and in active transcription.

Depending on the phase of the cell cycle the chromatin can be found in different states, relaxed or compacted. The most compacted state is the metaphasic chromosome, the super famous X-shape we all think about when we hear "chromosome".

At least one nucleus in the picture is preparing to enter in the metaphase and the chromosomes bodies start being visible: can you spot it??

Lucretia found a weevil during the live and she called it Wywee.

Normally they play dead (thanatosis) when they feel threatened (っ- ‸ - ς) so they tuck in their legs and antennae and just drop. Wywee is clearly minding its own business, no idea it is being watched from us!

Did you know that Curculionidae is the largest animal family on Earth with over 80,000 described species, more than all vertebrates combined ( ˶°ㅁ°) !!

Lucretia just infodumped Aya Brea?!

The term "spontaneous human combustion" refers to cases in which a human body is found with significant portions of the torso reduced to ashes, while the head and extremities show much less damage and the immediate surroundings of the body are only minimally affected. Typically, no observable source of ignition is found near the victim, and a foul-smelling, oily residue is noted.

In the past, such cases were erroneously attributed to supernatural causes, as the phenomenon tends to occur in the absence of any witneass.

A specific sequence of events is required for a human body to be reduced to ashes. The victim must first die from the initial flame, allowing the body fat to begin melting. A tear in the skin then has to occur so that the melted fat can soak into the charred clothing, igniting a wick effect that produces localized heat over an extended period. For this reason, the modern explanation favored today is the "fat wick burning" hypothesis rather than spontaneous combustion.

Manga Bosons (Particle Physics)

We wanted to make a hetalia/cells at work squad for the gauge bosons (and the standard model particles) so Hiroshi made them on stream! („• ᴗ •„)

Bosons are the particles that carry forces. There are four of them, one per force, and we gave each a soldier whose equipment tells you what it does.

The weapon/equip shows which force.

  • The photon carries electromagnetism, which is basically light and radio, so he gets a radio.
  • The gluon carries the strong force that holds quarks together inside protons, and that force gets stronger the more you pull, kind of like a rope that tightens, so he gets a bola gun (looks like a rifle but shoots bolas).
  • The W and Z carry the weak force, which only works at very short range and causes radioactive decay, so they get daggers.

Bag tells you the mass (photon and gluon have non because they're massless*), headband tells you the spin, medals tell you the charge. Look at the soldier and you've basically read his stat sheet ٩(ˊᗜˋ*)و

Lucretia made a Silksong biology bestiary with IRL pics

Hi all! I's Lucretia!
I'm a Biology Science VTuber from V-Choux ₍₍⚞(˶˃ ᵕ ˂˶)⚟⁾⁾
The community suggested me to post it here and on silksong subredrid so... here we are!

You can find the bestiary here: https://slides.vchoux.com/silksong-diary

Feel free to add feedbacks and suggestions!Let's make it better together ᕙ( •̀ ᗜ •́ )ᕗ
