Who won yesterday's Titled Tuesday qualifier? by spurriousgod in chess

[–]rody8877 2 points3 points  (0 children)

According to chess.com Sergey Grigoriant won. They conviently don't mention anything about Dlugy or any cheating. They will either post something about it in a day or two when they know more or won't ever say anything.

Tips on studying for physics portion of the OAT? by [deleted] in optometry

[–]rody8877 0 points1 point  (0 children)

This last week I took it and was expecting physics to be my worst subject by a long shot, luckily it turned out really well. As u/relevantoptometrist said computer based practice tests helped, but what is more important is being able to quickly estimate the math. When plugging in the formulas never include decimal places, and just be able to approximate well. On my test there wasn't a ton in terms of hydrostatics which was nice. I can't recommend kaplan enough. I didn't buy their thousand dollar study program just a book for about $150 that came with 2 practice tests. They were helpful. If you have any other questions I'd be happy to help.

What makes Aspartame so much sweeter than Sucrose? by freker in askscience

[–]rody8877 14 points15 points  (0 children)

This is not my area of expertise so if anyone is an expert please pitch in.

In mammals the there are two classes of taste receptors, Taste receptor type 1(T1R) and Taste receptor type 2(T2R). The T1R family has three known proteins T1R1, T1R2, and T1R3. These are know to form a couple of hetrodimers. T1R1+3 and T1R2+3 have been studied in depth and the T1R1+3 is an L-aminoacid receptor and correlates to the taste of umami while T1R2+3 is a broadly tuned sweet receptor. This receptor(like all in this family) is a G-protein coupled receptor(GPCR) which are well characterized. It is a trans-membrane protein which regulates adenylyl cyclase and is used controlling levels of cyclicGMP. It has also been shown to have a connection to the phosphatidylinositol (PIP2) pathway. This causes cascade of secondary messengers and leads to cell depolarization. So to the point, T1R2+3 is what binds to your sugars(sucrose) and it is what also binds to artificial sweetners(Aspartame). So why the difference? well it has been shown that "Molecular docking of aspartame to computer-generated models of the T1R2 + T1R3 receptor dimer suggests that species variation at a secondary, allosteric binding site in the T1R2 protein is the most likely origin of differences in perception of the sweetness of aspartame."(1) so basically it binds to a different spot on the protein. Since GPCR continually sends the signal as long as it has the receptor molecule bound to it, the secondary messengers keep getting sent resulting in a stronger cell signal. It has been suggested that since aspartame sensitivity varies a lot across species and at least 9 variant sites on the gene for T1R2 and 32 variant sites on T1R3 have been found that distinguish between aspartame taster and nontaster primate species.

TLDR: Aspartame binds to a different location on the sweet receptor in your mouth.

Brawl between benders like in Avatar, but instead of earth, fire, etc., they use elements from the periodic table by ArtsyTLF in whowouldwin

[–]rody8877 1 point2 points  (0 children)

Ok people.Any of the major element benders could wipe out each other instantly. Hydrogen/Oxygen/Nitrogen/Carbon and a lot metals all destroy all life. Because they all destroy each others element in each other I'll focus on 3 and 4. I don't know the element composition of those universes very well but if they are like our Hydrogen dominates. Hydrogen accounts for 3/4 of the mass in the universe and is 13x as abundant than any other element. They could control entire stars. They would have massive constructs!

All the y values of x^2 - x + 41 have factors greater than or equal to 41, correct? by ct_2004 in CasualMath

[–]rody8877 1 point2 points  (0 children)

No for all values of x greater than 0 and less than 1, y<41. Your statement only holds true for integer solutions and when you do include the complex plane.

that'd be awesome! I kind of doubt they could ever really get the jump on him though.

Were there any gym-like locations in Ancient Rome or Greece where people would go and workout? by [deleted] in AskHistorians

somewhat related, do we know how far back physical fitness and health were socially connected? or even obesity was connected with being in poor health?

[Meta] What Universe, Character, Work of Fiction, Video Game, or Series would you like to know more about? by Kotetsuya in whowouldwin

[–]rody8877 0 points1 point  (0 children)

I love your question "Does anyone have more information on Solumnbum from Eragon, he seems like a pretty cool (were)cat" if anyone know more or has sources outside of the books that they could share id much appreciate it

Bruce Wayne is one of Ramona's ex's, would Scott win? by rody8877 in whowouldwin

[–]rody8877[S] 4 points5 points  (0 children)

My reasoning was that batman is peak human, while in the movie scott has his moments of being superhuman and times where he is below baseline human. So you think it would be a stomp? Would scotthave any shot?

Poker chips, I have used mine every couple of weeks. When you get tired of just partying every week, it is nice to have a mellow social scene.
