e8wh8k | - i saw a ted video today about altering the dna in bacteria to fight cancer. how does one "edit" the dna in something?? | In the video (and similar videos I've seen) they say that they change the DNA to change the organisms' function, but not how they do it.
I know DNA can change through mutation, but how do geneticists alter DNA sequence?? | explainlikeimfive | https://www.reddit.com/r/explainlikeimfive/comments/e8wh8k/eli5_i_saw_a_ted_video_today_about_altering_the/ | {

1yl8u8 | why does the us have less money now than it did in the mid-20th century? | Reading about World War 2 -- It seems like the US had unlimited industrial capacity to produce planes, bombs, aircraft carriers, etc. Has the US government simply shrank, or what's going on? | explainlikeimfive | http://www.reddit.com/r/explainlikeimfive/comments/1yl8u8/eli5why_does_the_us_have_less_money_now_than_it/ | {

7d6mv0 | How could the "stab in the back" myth have formed if Germany had essentially become a military dictatorship under von Hindenburg and Ludendorff? | Title.
I read that they basically ruled the German Kaiserreich as dictators. If I understand the "stab in the back" myth correctly, part of it says that the government betrayed the German military. If *they* were the leaders of the government, how could it have betrayed them? | AskHistorians | https://www.reddit.com/r/AskHistorians/comments/7d6mv0/how_could_the_stab_in_the_back_myth_have_formed/ | {

1gkp6i | why are there flights that take longer than 12 hours? | When I flew from Chicago to Shanghai, it took 16 hrs. However, since the Earth spins at a rate of 1 rev/day, it seems like the furthest a flight should take for something almost directly around the world is 12 hrs. I think it might be because the atmosphere is part of what spins as well, but I'm not too sure. | explainlikeimfive | http://www.reddit.com/r/explainlikeimfive/comments/1gkp6i/eli5_why_are_there_flights_that_take_longer_than/ | {

tr4hx | Is is any more likely that the universe is not expanding, but that every point or particle in it is shrinking in size?
