  • Congenital? No. Acquired? Yes. The area of the brain that processes and interprets sound has to develop. Without sound input as a child, that won’t happen.

    Current leading theory of tinnitus is called the ‘central gain’ theory. This is where the brain becomes accustomed to seeing signals from the ear at a certain level, and when that neural level is no longer at that level it will add in its own noise to make up the difference. This noise is then perceived as a tone or sometimes a broadband sound, commonly described as either a ringing or a whooshing sound. Sometimes it can also be described as crickets. Depends on the person and cause. Not all hearing loss comes with tinnitus, but most tinnitus comes with hearing loss. In audiology school we had a whole class on tinnitus and covered many interesting aspects exactly like your shower thought here and went over papers on every angle you could think of. It was fun. But in the end, the brain has to at a minimum know what sound is to even perceive sound.





  • While China is quickly becoming a global leader in clean energy adoption, it still has some work to do. The nation still relies heavily on coal-fired power plants and will need to retire those facilities in favor of more sustainable options in order to truly offset its CO2 emissions.

    This is a bit of an understatement. China leads the world in both renewable energy usage AND coal use. And by a lot. Then they also lead in steel production with older blast and coke furnaces that are super CO2 intensive. And in concrete production and use, also super CO2 intensive.

    I’m not trying to shit on the progress they have made. It is nice to see them taking this more serious than some others. But this article kind of green washes their energy, overplaying their renewables and not even mentioning their dirty power.



  • Fun fact, in the book Jurassic Park and in the initial script, there was a river boat sequence. It was extensively planned in preproduction and teased as part of the plot. This was spread to the other ‘tie-in’ merchandise and park ride. This is why the universal studio ride is a water ride and why games that timed their release with the movie had river sequences. But as we all from the future know, it never happened. Budget overruns and shooting delays lead to script rewrites to cut out that sequence.



  • Seriously. We are talking about tire tread compared to weight. Both use multiple sizes of tire depending on the year/model. There are a few that overlap in diameter to get the closest to comparison but they still have a very different width. We are talking about a 235/35R18 vs a 235/75R18. That is a huge difference in wall height/aspect ratio and changes how the tire gives under power. Those numbers massively change depending on model as well. Something like an f150 raptor could have a 315/70R17, almost a foot wide. So comparing just the weight and saying they are close enough is far from a fair comparison.




  • While any aircraft sent to ukrane is nice, I sure hope they aren’t paying much for them. That airframe is about 60 years old with the last major design overhaul in 1990 and its last electronics upgrade in 2000. They would be better off buying F15e’s or even the new f15ex. He’ll, even getting some last Gen f16’s or f18’s over there would be as good or better, but cost probably more. The f15 though is probably the best multiroll jet for the cost.

    Now, if we are talking about sending some OG Mirage 2000 fighters over there, then that sounds like the ultimate white elephant gift France could give. The US could sent some F4 phantoms over while we are at it.

    The big news I the training of 4500 pilots. That is huge. If they could do that, then the mirage 2000 could basically turn into their base fighter trainer and use it as the training wheels to get the new pilots experience and into bigger and better things.


  • I have an honors minor in medical humanities and took several medical policy courses. We looked at this exact graph from previous years as well as several other huge sets of data/graphs/studies and anything else related to insurance you can imagine. Insurance is not a standard market commodity and does not follow the same trend or logic. The only way you can lower premiums in insurance is by reducing the risk in the pool, or increasing the pool size to dilute the risk. This is either increasing the total pool size by increasing premiums, getting more people, or being selective about who joins the risk pool. The third one was what was called “preexisting conditions” and kept high cost people from entering the risk pool and draining the funds. This got banned and increased premiums. By increasing competition you end up splitting up the pools, making everyone’s premiums go up. This happened multiple times post ACA after the GOP started stripping out the funding and safeguards to prevent this. More and more competition opened up with artificially low premiums being subsidized by federal dollars, but then when the subsidies ended the premiums started jumping. Then when the premiums were jumping, new companies opened up to make more competition advertising lower rates, but then further fractured to pool sizes, leading to premiums skyrocketing. If you look back just 10 years ago there was a 3-5 year stretch of premiums increasing almost 30% year after year. It was due to all the competition opening up every year. This is why single payer systems have the lowest rates. If you have even one private company monopoly with a regulated cap on profits you would still end up with lower premiums. Then, if this single paying company was nationalized to take out the profit making middle man, the premiums are that much lower because your risk is spread across a massive pool. More competition in insurance makes the problem worse. I would agree with your stronger regulation though. There is a lot that can be done there.


  • That is at a ‘state’ level, there are still smaller level communist places to live. Like where the word ‘Commune’ comes from and what communism was derived from and attempted to expand into. There are communes all over the world. US included. There is a famous one in London, lots of large ones in Spain. They are communities that exist in their own bubble of micro economics within their larger communities of normal living. You should look it up. They are interesting and normally very appealing.
