Then you find out that the lack of an ingredient results in the microbes producing the product lol.
Certain algae for example, need to be “starved” in a way that results in them switching from conventional photosynthesis that produces glucose to photosynthesis that functions to generate Hydrogen and Oxygen alone. The Oxygen is used for respiration and the Hydrogen is essentially dumped as a waste product. They can only sustain this for relatively short periods before their stockpile of carbohydrates is sufficiently depleted. Which means these bioreactors need to be cycled through a fattening phase where the algae stockpile fuel and a starvation phase where they exhaust that stockpile while producing Hydrogen.
Ive been trying to keep tabs on the literature in biochemistry, chemistry and other fields for decades. I inevitably come accross things like this from time to time. These particular articles I just googled because I dont have the bookmark for the original paper discussing Hydrogen production back in 2000.
I don’t know, there are lots of PhD programs in the U.S. where you’re a research assistant, which basically means your tuition is free and you’re paid a stipend for the research. In my experience, I’ve only met US PhD students who were fully funded.
I think people think that having to TA means they’re not being funded or something like that. If you’re getting into a program that doesn’t fully fund you, then that program doesn’t want you or it’s not a good research program. All reputable PhD programs fully fund across disciplines.
Yeah, I got paid to do gradschool. Not much cuz I didn’t shop around and just stayed where I did undergrad, but yeah, once you’re doing research, they should be paying you.
This meme didn’t show the revolving lab door, the giant corporate foot over the biochems head and the minimum wage employee who makes more money than them.
At work we have a scale sensitive to the 1/10,000 of a gram. 4 decimal digits. It’s so sensitive it needs to be encased in a box so tiny connection currents don’t make it go frantic! Even in the box the number changes a lot. 15 0s is nutty.
Mine can tell if I’m sitting next to it’s desk or not. I’ve come to the conclusion it’s the deformation of the ground the desk is sitting on.
It’s really a silly amount of precision for what I use it for. But It’s so fun to lock g on .0000, even if only for a few seconds. Anyone who has a target of a specific amount of 0s can do it themselves. After the first 2 shits pretty random.
No no no. The error compounds every time you math so if you math a lot at 40 digits you might end up with like 30 digits of correct precision. Totally unacceptable. Literally unplayable.
The worst? I stopped to do research after my PhD and now, I forgot everything. Dumb as a rock AND without any useful knowledge of my very peculiar subject.
Memory Masters destroying the last of their childhood memories so they can add another 80,000 digits of pi to their mind palace.
contextMemory Mastery is a technique where you force your brain to remember random information by formatting it in a certain way, some people have gone on to use this trick to memorize millions of digits of pi. A study recently came out confirming that every time you make a new memory it destroys an old one, so every time someone makes a “memory palace” it comes at the cost of older memories, such as in childhood.

If that was true, babies would forget their first memory every time they remember their second memory. There’s no way it’s true. It might be partly true, but it can’t be completely true.
Well the way memory works is that it allocates certain clusters of neurons to storing information. When you’re young there’s a lot of blank space that you can store stuff in but as you get older you start having to pick and choose as more and more brain space gets taken up.
Here’s a cool video on the subject: www.youtube.com/watch?v=X5trRLX7PQY Fun fact: because of how memories are formed in chains you can tell if you’re on the precipice of forgetting something if you try to recall it and you start trailing into another memory. You can experience this for yourself by trying to recall the beat of an old song and note when it starts morphing into the beat of a newer song. It’s also worth noting that every time you recall a memory you destroy the original and rewrite it, bringing it back to the top. That little asshole is like 90% of the reason why our memories suck so much shit and are so prone to outside manipulation.
