    So I'm a middle school science teacher and I defiantly showed this episode to my life science students today and had a class discussion about it

      Do your school staff not like RT?

    Chris, holy hell STOP looking at Sally every 2 seconds! XD

    Chris could've answered the first question in three words:

    I love the show, but hate the name. I really liked the Let Me Clarify title a lot better. Also there is another show that has Spot in the name.

    I (a scientist myself) really like the show, and really like Sally, but I think it would be better if the science featured wouldn't be just limited to biological questions. Maybe you could find some other scientist (e.g. physicists, chemists) to either take turns with Sally or supplement her.

      Special guest star Neil Degrass Tyson, or Bill Nye?

      I here there is actually a couple of editors in Achievement Hunter that have various science degrees (i think i heard it in a video), maybe they might want to do some? I would really like so see some of their "how the universe works" questions.

    Could we get Sally on Always Open?

    Once filming resumes, Treyco should be brought in for any engineering/physics based questions.

    I was leaning into the screen and then,.. BAM!!! it was over,.. then there was sadness. can this 'Spot' expand to a 'blob',.. or 'puddle' at the very least?

    Seriously,.. can we drive these discussions further?

    Anyone else get flashbacks to Professor X's speech from the start of the first X-Men movie when Sally was talking about gradual vs punctuated evolution?

    "Mutation: it is the key to our evolution. It is how we have evolved from a single-celled organism into the dominant species on the planet. This process is slow, and normally taking thousands and thousands of years. But every few hundred millennia, evolution leaps forward."

    In the C - F conversion that popped up, since it was an increase in temperature, should it not have read "17c = 30.6f"?

      For those who don't understand why, this is because degrees of Celsius and Fahrenheit are measured in different sized intervals. The difference between 0 and 1 degrees in Celsius is 1.8 degrees in Fahrenheit. Thus a difference of 17C, which is what Sally was talking about, would be a difference of 30.6F. The conversion shown in the video is the equivalent temperatures and not the equivalent differences in temperature. Well spotted, @Stanty16 !

    I don't expect an answer but this made me curious about Sally's flies that glow green in UV and I don't know how to phrase the question. Do you also get variations in the green and the glow? So like if a fly was glowing slightly yellower than green would that be selected for or discarded? And would a fly that fit the green category but it's glow was dimmer than the majority of the other flies be discarded?

    Obviously that would depend on the conclusion you're after but would that be considered a weak and irrelevant variation in the trait you're trying to select for or is the variation in a trait less important than actually having the trait at all?

      This would depend on if the 'glow green' trait was discrete or continuous, and by that I mean is the trait that gives the fly its green glow a single gene (so a green or not-green) or a collection of genes all contributing to create the green glow. If the trait was continuous (such as height) then any variation in one of the genes may result in a variation in the 'green' phenotype, which theoretically may mean a different shade. However I believe, having worked with fluorescent organisms myself in the lab, that the green glow under UV light is dictated by the single GFP gene -- which has been cloned from an organism such as jellyfish and then inserted into the fly's genome. In which case the fly offspring wouldn't have variation from the gene, such as you would with a continuous trait of height, but would either be the intitial green glow shade or not (much like if someone has a heritable condition like cystic fibrosis or not). 


      Of course as we advance through genetics we find that things are more and more complex than we initially thought, so there may be other genes which interact with the GFP gene (epistasis) to give the appearance that there is continuous variation in the trait -- however I currently believe this is not the case with Green fluorescence.

      All this is based off my own biological experience in my career, I do not work as a green fly breeder though, so apologies if some of my details do not accurately translate -- but I'm sure the genetics are the same!

    All I could think of the first half of this episode was Gavin and Michael playing Manual Samuel.


    Also, if you are interested in how to train yourself to hold your breath for incredibly long periods of time, David Blaine did a Ted Talk about how he held his breath for 17 minutes.

    Of all the evolutionary traits, I feel we need tails.  Prehensile of course.

    I think we all want longer episodes, but it is difficult since Sally is still in the middle of her doctorate in England. And of course they shot all the episodes within a week or so during what I'm guessing was her Christmas break (so almost no chance of the episodes lengthening throughout the season). 


    BTW if you guys are curious about Sally's green flies, my guess is that she is using "Green Fluorescent Protein" flies. GFP animals are really fun to play with so I recommend that people google them.

      well considering she films all of these when she visits the states between doing her doctorate in England, It would be hard to do that unless she abandoned her studies and moved to the states.
