^^Pretty interesting post.
I think it still makes for a good case study on why conspiracy theories are so popular despite being so often wrong. It's a classic because it's a coherent and simple narrative, pitting good guys against bad guys. It explains simply a complex and extremely boring process that resulted from the decisions of millions of people over decades. It invokes nostalgia, outrage at big companies, and anger at perceived injustices. It rests on a foundation of truthiness. And critically, the story can be told much more easily than it can be debunked.And no one thinks this is a crank conspiracy, because it seems to come up in literally every conversation about LA transportation ever.
GM may have put one of the nails in the streetcar coffin, but it was one of many nails and not even the last one.
TIL that your grandparent's diet can affect your health.
Every cell in your body has a complete set of DNA to form anything from a muscle cell to a neuron. But what tells each cell to become what it is, is called gene expression and is determined by “methyl tags”. Methyl tags are hydrogen carbon compounds which can attach to a gene and block other proteins or enzymes from attaching thus preventing the gene from being expressed. These methyl tags can be changed based on environmental factors like smoking, diet, stress, etc.
Moreover, when a new embryo is created there is a process that removes the methyl tags that come from the parent's DNA but this process is imperfect so some of the tags remain. Researchers think that in humans it can take up to 3 generations before these tags are removed. So the environmental factors that your parents and even grandparents go through can actually affect the expression of your own DNA. Since DNA expression plays a large part in basically everything about you, your grandparent's diet can affect your health.
Pretty cool![]()
TIL that XKCD has a tooltip on all its comics when you hove your cursor over it. I don't know how I managed to go this long without noticing it
Scientists in California have developed a strain of yeast that can be used to brew cannabis extract rather than beer.
With just the addition of sugar, the genetically modified yeast fermented to produce pure cannabinoid compounds including mind-altering THC and the non-psychoactive CBD, which is used medically to treat conditions including chronic pain and childhood epilepsy.

The team said that using yeast would be a “greener” way to cultivate cannabis, which is a water-hungry crop and is often farmed using heavy quantities of pesticides and fertilisers. Indoor growing under lights and with ventilation fans uses a lot of energy – one study estimated that California’s cannabis industry accounted for 3% of the state’s energy usage.
