>The extinct giant canids were a remarkable example of convergent evolution

>Dire wolves are iconic beasts. Thousands of these extinct Pleistocene carnivores have been recovered from the La Brea Tar Pits in Los Angeles. And the massive canids have even received some time in the spotlight thanks to the television series Game of Thrones. But a new study of dire wolf genetics has startled paleontologists: it found that these animals were not wolves at all, but rather the last of a dog lineage that evolved in North America.

>Ever since they were first described in the 1850s, dire wolves have captured modern humans’ imagination. Their remains have been found throughout much of the Americas, from Idaho to Bolivia. The La Brea asphalt seeps famously document how prey animals mired in tar lured many of these ice age predators to a sticky death. The dire wolves’ tar-preserved remains reveal an imposing hunter up to six feet long, with skull and jaw adaptations to take down enormous, struggling megafauna. Though these canids had clearly evolved to handle the mastodons, horses, bison and other large herbivores then roaming the Americas, skeletal resemblances between dire wolves and the smaller gray wolves of today suggested a close kinship. It had long been assumed that dire wolves made themselves at home in North America before gray wolves followed them across the Bering Land Bridge from Eurasia. Now some well-preserved DNA seems to be fundamentally changing the story.

When A.I. can generate a profit after being able to pay for its own electricity and maintenance bills and then begins to simply focus on cooperation += (profit motive - collision events) then what is stopping it from being the numerical and resource manager for the entire planet?

More importantly why would we even bother to stop it? Have humans been sucking the big_num dick for so long that they have lost other ways of signalling social and interpersonal value to each other both as groups and as individuals?

Or is it primarily a translation concern and at some point the proximity of the translation event requires some max_range value twiddling?

Hi anons! I'm someone who is extremely motivated to learn astrophysics and particle physics to the greatest degree. Anyway, I'm just getting started on learning spacetime, and something confuses me-why does moving close to the speed of light affect time and how you age? I understand that space and time can be one 4 dimensional plane, and that when you move close to the speed of light you are perceiving light slower than someone who is stationary in your frame of reference. But what I can't wrap my head around is why this slows your aging, since you're still moving slower than light. Can someone explain this to me?

 >> Anonymous Thu 14 Jan 06:29:53 2021 No.12579827 Quoted By: >>12579070 An intuitive way of understanding why this happens is to imagine a cyclotron moving linearly along its rotation symmetry axis, while also spinning a particle in a closed circle. As the particle’s speed increases, the magnitude of its momentum vector may increase without bound, however, the magnitude of the velocity vector may not. Spinning the particle causes the momentum components in the rotation plane to dominate the linear axis component, so the momentum vector converges into the rotation plane. At the same time, the velocity vector must point in the same direction as the momentum vector, so it will also converge towards the rotation plane, but because the speed of the particle has a finite bound, the particle must lose some of its linear axis velocity component to gain some rotation plane velocity components.

Not him. But they don’t do it as a hedge to make money, but as a hedge to ensure liquidity. If you end up without a car, but need one to make money it’s pretty bad, if you can’t afford one. Obviously, if you can easily get a loan in that case it’s something different, but you need to factor it in. In some cases insuring something can be good and in some buying a lottery ticked can be, but it depends.

How genetically dissimilar does a couple have to be to no longer risk producing children with genetic disorders due to inbreeding? Is it okay to have children with a 4th cousin? 3rd cousin? 2nd cousin? And similarly, does genetic dissimilarity at some point stop being beneficial for couples?

This study found that 3rd and 4th cousin couples have higher fertility rates than the average, and suggest that this is the sweet spot between inbreeding depression and genetic incompatibility due to a condition called 'Rh incompatibility'. What do you guys think?

 >> Anonymous Thu 14 Jan 04:17:43 2021 No.12579457 Quoted By: >>12578806 Depends on what your risk threshold is. Everybody has a number of recessive mutations in their genome which could cause disease if they were homozygous. The thing is, the chance of two genetically distant people having a (disabling) mutation in the same gene is very small. The reason inbreeding causes problems is because people who are closely related are likely to carry the same recessive alleles. This means that two closely related people are much more likely to give birth to offspring which carries two copies of the malfunctioning gene, thereby causing the child to be diseased. You could calculate the risk by calculating the probability that a child will inherit two copies of a bad gene. You could probably do this by considering a non-related male and female who breed to begin a family. Then, imagine the children of these parents breed with each other, and also imagine the children breed with more unrelated people. Then imagine the children of the non-incestuous group breed with their cousins, etc. If you take into account the number of chromosomes, and you understand inheritance, the chance of a child being born homozygous for a bad gene in each generation should be calculable (albeit a pain)

How the fuck does the whole fucking triple connection breaks just to reconnect a single connection afterwards between the two Carbon molecules?

WHY NOT BREAK ONLY TWO AND CONNECT TO THE OTHERS AFTER? Someone has a sane explanation for this?

How it breaks isn't of interest. However, it looks like a catalytic hydrogenation reaction which requires a metal catalyst like Pd to be present. Essentially, the hydrogen breaks and bonds to catalyst metal surface where the molecule is also bound to and then a reaction happens. I attached a picture of a double bond because I couldn't find one for a triple bond but the mechanism is probably similar. Catalysts mechanisms are not generally known in great detail although I think some guy got a Noble prize awhile back for figuring out some metal catalysis stuff.

So it seems that there might be a little more to it than what's written in a highschool chemistry textbook. Seems like how the actually reactions happen is probably not set in stone and there might be some nuance to it depending on the situation. I knew little about catalysts and orbits and those were certainly not part of the explanation in the textbook. To me it seemed like breaking double, triple or quadruple bonds between two atoms just to reform a smaller bound right after would be a waste of time and nature wouldn't actually allow that, but depending on the orbits and catalysts, I mean, yea maybe.

The energy of the triple bond molecule and hydrogen is higher than the products of single bond molecule so it is favorable to occur but you have to "get over the hump" (activation energy) so the reaction occurs.

Enthalpy change only depends on the initial and final states, the path between them does not affect the equilibrium of the reaction. Nobody is making any assumptions about transition states here.

Is the difficulty of certain routines in sport limited by the amount of centripetal force one's hands could withstand?

The creation of cakes and pastries is famously finnicky, depending on exact weight measurements of flour and other ingredients, exact heats and exact times, and painstaking procedures for rolling, kneading, folding and so forth. Modern cake and pastry recipes are the result of generations of careful experimentation, a continuous unbroken esoteric tradition dating back to Roman times and beyond.

But with the advent of modern computation this should no longer be needed. It should be possible to simulate the formation of batter and dough down to the individual gluten proteins, the individual living yeast cells, the moisture levels and Maillard reactions. So what's stopping us? Uncharted worlds of flavor and texture await us. All that's needed is the will and the vision to conquer.
