I can curl up and wait for stress to pass too... it's just REALLY upsetting to everyone else in line at the grocery store, is all.

[@BlaBla-pf8mf]

It's not the curling that is distressing, it's the wailing.

🤣🤣🤣👍

[@MagicianFairy]

Turning red and curling up into a ball when stressed? This is the most human sounding cell I've heard in awhile.

[@myrmatta1]

I found some of these in their cyst state in my birdbath a while ago. The bird bath also had a few rotifers.

[@jasonabettan5778]

I think name "Blood Berry Pink" is something that might actually catch on.

[@Faquarhl]

In german the species used for it's Astaxantin (H. pluvialis) is basically called "Blood Rain Algae". "Blood Berry Red" probably sells better in food products though.

[@outdoorsy01]

Another amazing overlooked wonder. My bird bath always has a red rusty look to it

[@jadeswormfarm]

Would be very interested to see you do a video on what's living in kombucha liquid and/or scoby 😊

[@unvergebeneid]

It would be really fun if you could occasionally show pictures of where the specimens came from. Mesocosmic pictures I mean.

[@tissuepaper9962]

"Mesocosmic" is so much better than "macroscopic". Never heard that word before now but it has just entered my lexicon along with the logical extensions "microcosmic" and "megacosmic". Thank you.

This is Hank! Check him out on SciShow for the his polar opposite of expression. When I watch the first one of these I was stunned to find that he was the one teaching us such interesting things about these little beings.

[@jarmengolalbanell]

Fantastic detail and colors! The new microscope really worth…

[@viochrys]

5:19 so when it's at unfavorable surrounding it released astaxanthin as an extra protection I presume?

[@ianbcnp]

I think it is reflecting more wavelengths of light so the haematococcus is protecting itself from being in the glare of more light that it can cope with. Algae need light but not too much. Light which is too intense can damage many algae - hence the protective colouration to reduce the intensity of light entering the cell.

[@dgtzbhunj]

I work with Haematococcus in the lab at the uni. As far as I know, the antioxiant properties of astaxanthine protects the DNA from degrading as it takes up the free radicals that are produced by unfavorable conditions. We use high light intensities, mainly blue light to stress the algae and about a week later they are completely red. To go back to the zoospores it takes a bit longer. If the conditions get better, i have observed that they can directly divide as a aplanospore

[@tissuepaper9962]

@@ianbcnp I'm looking at a couple of absorption spectra of astaxanthin (admittedly I did not find one in aqueous solution) and it looks like it absorbs heavily in the near UV and well into the greens in the visible spectrum. I think a more conplete explanation of the adaptation is that astaxanthin absorbs most of the more energetic portions of the sunlight falling on the algae, so that it can never be absorbed by chlorophyll, and then reflects the reds and infrareds to remain cool. It's basically acting as a perfectly placed notch filter on the incoming sunlight, only absorbing the parts that would otherwise cause its mitochondria to produce ATP, and reflecting the rest to stay cool. Very cool stuff. (This is all speculation, I have done no research into haematococcus beyond looking at absorption spectra of astaxanthin and watching this video)

[@ianbcnp]

@@tissuepaper9962 Thank you for the much more complete and complex explanation. I think I was on the right track but it looks as if it's an amazingly well honed way of dealing with excess light.

[@backpacker3421]

How do you know what interests Haematococcus? Those little guys could be completely fascinated by our relative desire to synthesize a chemical it produces naturally.

[@willemvandebeek]

But what is the big transparent bubble around the Haematococcus with a red centre?

[@tristandeniet]

these jpegs are so crispy

[@a.j.kimball1240]

Have you guys ever heard of Tantulocarids? They are incredibly interesting and honestly quite disturbing little critters. Some of the smallest crustaceans that can give birth to themselves. Unfortunatly it would probably be very difficult if not impossible to get your hands on them since they tend to like living on fish and in ocean currents.

[@gregoryfenn1462]

Did the plant kingdom evolve from algae? Or do they have a close common ancestor (closer than animals or fungi)?

[@ngls]

Afaik they did, as some algae are single-celled plants. The first single-celled plants probably originated from a cyanobacterium entering a eucariotic cell and somehow forming a new organism this way. So you could basically say that plants evolved from both animals and bacteria. If you want to know more, look up the chloroplast wikipedia page.

[@Dragrath1]

Well it can be yes and no as it depends on what "algae" you are referring to since algae as a whole if not distinguishing beyond that is paraphyletic. Plants are descended from green algae which adapted to life on land via a partnership with fungi and all green algae share a common ancestor that was a green algae. However their sister group the red algae while closely related likely obtained their chloroplasts independently as there are a few intermediate relatives which are true heterotrophs. Its hard to say exactly how they are related since the split between red and green algae occurred well over a billion years ago in the mesoproterozoic. Other linages of algae are far younger for instance the brown algae or kelp lineage only appeared during the Jurassic

[@blacksflash]

What are those little tiny things swimming and squiggling in the background?

[@Bcarr122391]

[@МедбратН]

Sorry for the question, but what brand of microscopes do you use?

[@NibblyBitz]

Haema does this part of the word mean red just wondering does anyone know the origin of how the Haematococcus word came about. Thanks

[@Teknokraatti]

Haema comes from the greek word αίμα, or aíma in latin alphabet which translates to blood. As explained in the video, the algae of course have no blood (Or any circulatory system whatsoever), but nevertheless can be similarly colored. Red would be κόκκινο, or kókkivo.

[@1Cr0w]

I never realized that algae can have flagellum? I thought they were only found on animal type cells.

[@tuomasjarvenkyla6739]

you would think! go read about the ginkgo tree's reproduction for some really interesting stuff

[@faye7199]

The male gametes that moss produce have flagella. It is essential for them to swim through the moisture and reach the female gametes. The same can be applied to ferns. These cells are photosynthetic rather than heterotrophic ( or “animal-like” as you say).

[@infinateU]

Are individual blood cells (platelets) supposed have their own “negative charge”?? If so, what does consistent EMF Exposure (milliWats from RF {Radio Frequency}) “do” to blood cells??

[@martf4701]

Astaxanthin sounds strangely to Zantac or Xanax. Acid reducer. And Negative fealling reducer. So i ask my self.. Are negative feallings, like depression, the result of molecules or substances in our brain or body being too much acid?! Are acid molecules negatively charged ? ( lacking electrons )

[@00Skyfox]

What are those far tinier things swimming around the algae cells?

[@faye7199]

Those are bacteria cells.

[@StrangerHappened]

*WHAT* are those tiny moving things around? Some of them are moving in a very particular way, so they are not just random pecks of dust or waste.

[@faye7199]

Those are most likely bacteria. Bacteria are prokaryotic cells, meaning they lack membrane-bound organelles and nuclear envelopes. All bacteria are quite small compared to eukaryotic cells such as the haematococcus.
