You just helped me understand a 15 mark answer of genome sequencing in a few minutes (I am working on graduating in Zoology). Thank you so much!
4:30 "Rough tooth rough" is what my dog says when he wants a treat.
p.s. I liked your explanation of Illumina Sequencing, I wondered how it worked. I used the Sanger method, back when I was in genetics. (yes, I'm old) I actually thought about using Lego bricks to help explain things to new employees lol
Oh my gosh, Brit. I'm so glad you were allowed to advertise your channel on SciShow Psych, because otherwise I would have never found it. Your videos are great, and the views will definitely keep coming in. Keep up all the hard work, because all of us animal and nature lovers stuck at home, or stuck in some shitty dead end job unable to go to college, these videos are so important to us. Thank you! I'm 28, and this fall I'm finally going to college for the first time to pursue a wildlife biology degree. I'm absolutely terrified, but when I watch your videos and others like it, it really helps me gain confidence and stirs up my passion for the Earth, especially when I'm thinking too much and getting in my own head about fucking up college. Thanks again.
Thank you SO much- best wishes on college!! - Brit
Wow! That seams extremely hard and complex! But you explain it very well.
This video was highly informative ... but it massively corrupted my TH-cam suggestions! Up Next is "Baby Shark", and all the rest are young kids playing with slides, Barbie dolls(r), reviewing toys, et cetera!
This was a great video! I've been fascinated by sharks for a long time. The mako has always been my favorite.
I liked the way you broke down sequencing into such an easy visual way.
You still like me tho, right?
@@bruceshark5501 Like you, but prefer seatigies (the stripey ones)
Couldn't help but think of Friends! :D Thanks Brit; your skills in lecturing are amazing and your passion is infectious!
Awesome! 🦈 thank you for the LEGO explanation
I feel like this paper was chosen so that Brit could play with children's toys!
Nah, it was just a convenient teaching device...I would have discussed this shark paper either way haha -Brit
Fun fact, Carcharias is the literal translation of the word shark in modern greek (karcharos is ancient greek). So I've been using their classification name my whole life without knowing! Would be fun for an outside observer.
Brit, you are phenomenal. Also, you are a winner of the genetics lottery
I want you to know that I'm not a fan of these beach-terrorists, but will abstain from further criticism and watch because your intro was great and your enthusiasm is infectious.
I'll take it 😂
You can always tell when someone is talking about something they’re passionate about! I’m so glad Britt was able to make a video like this. It’s amazing how little we know about sharks, so this is very exciting. Brit did such a fantastic job explaining the gene sequencing; it made this FL nerd very happy 💜 using the LEGO to help was genius.
We love you, too...
Thanks for being a positive, intelligent, and proactive supporter for my "people"...
Being a great white shark is jawsome, and we do appreciate humans like you helping dispel old ideas about my species, Carcharodon Carcharias, and let people know we are fascinating, and truly fintastic.
Keep up the good work.
Happy international year of the sharky!!!!!!!!!
Fun Fact: Many fish species like Tuna,Goldfish etc are more related to us, than they are to sharks.
Great video!
I love the brown banded bamboo shark!
Great video, even more so the part about gene sequencing: one of the best explanations I have seen. I hope the sequence more individuals. With our modern powerful GPUs computer time is no logger the main issue. I hope with time the Hebert cost and time goes way down. Until that moment this studies will continue to be like the NMR ones: very difficult to generalize
I want some more research about loan sharks though. They are quite evasive
I'm in love with your brain, and your channel..
Cheers! -Brit
Great job on the sequencing process, that was really interesting!
On a separate note, I wanted to suggest a topic I've been thinking about for a bit. Model organisms, and how scientific research relies on them. What's it mean to be a model organism? I'm curious how the scientific community decided if a species would be a 'good' model organism. Also, are there drawbacks to relying on model organisms?
I absolutely LOVE that topic! I'll look into it and see what's doable :) -Brit
priming is real...goddamnit, those hearts made me think "rose upon rose of teeth"
I know I just got here, but I would like to request, if it isn't too much of a hassle for you, a video about orcas, please.
Orcas are just giant dolphins without the weird fetishes.
@@pigeonfowl474 pretty sure they're just as rapey and bottlenose dolphins
I was thinking about doing an episode on the new orca species in the southern hemisphere so hey, that just might work! -Brit
At 8:23 are you talking about qPCR?
great stuff!, I wonder how much can be assimilated by high schoolers.
So did I miss the episode where she scuba dives with sharks or has she not done it yet?
Nope, it hasn't happened yet! But if you want to fund a trip for me to do so, I'd be down haha -Brit
_Jaws theme intensifies_
Cue my iconic theme song.....
I want to run a research centre /lab and manipulate great white shark DNA/RNA , it’s just a matter of turning off certain genes , I wish to create a new shark larger , the great white liger as it were , except created in a lab . Maybe cross one with a whale shark then release it into the wild . With so many whales they shall have ample food .
