> Cell sizes are not fixed, however, even within a single species. Cells often swell as they increase their production of proteins and metabolites in preparation for division. This is in line with biology’s only rule: namely, there are exceptions to every rule!
> Case in point: a giant bacterium called Thiomargarita magnifica can extend about one centimeter in length, so large that it can be seen by the naked eye. It does so by breaking the surface area-to-volume rule, filling between 65–80 percent of its internal volume with an empty vacuole. In other words, it pushes most of its molecules to the cell periphery, thus shortening diffusion distances.

Collected and stored sediment samples were found to have surviving T. namibiensis cells after over two years. The cells had no access to any added sulfide or nitrate during this time. In the surviving cells, there was a notable size decrease. To survive without growing the cells depended on the nutrient stores of the central vacuoles.
Indeed. It says they rely on two different substances which normally don't mix (nitrates and sulfites), presumably because if they were both present at the same time they'd react with each other directly without the bacterium extracting any energy from that. So they live in places that sometimes have one and sometimes the other, and have to store one of them until the other comes along, which can be years. Or that's how I read it.
It’s hard for me to know where my pessimism stops and my realism begins with these kinds of experiences lately. The latest iTerm2 update had me subconsciously questioning my own philosophy around whether I ever would want or need an AI agent [that someone else] built in my default terminal application.
That feels like a kind of useless conversation though, there are no facts involved.
Once Google had implemented the change they’ve outlined here someone can plug their phone into Wireshark and see what, if anything, has changed. Then there’s a conversation to be had.
I may be wrong, but I think user 22c may be trying to point out that we put an amount, W, of CO2 into the air by making the collective decision to fly so many planes in the first place.
More specifically I was talking about equating contrail reduction with removing carbon from the atmosphere, which the article does when it says
> Marc Shapiro, the head of contrails at Breakthrough Energy, calls reducing contrails [...] the equivalent of removing carbon from the atmosphere at a cost of 10 dollars per ton or less
Contrail reduction and carbon sequestration aren't the same thing and it's not fair to equate them on cost.
> ...government digital services and apps need to become less bureaucratic and formal.
> Beijing asserted that it wants a "user-centered approach," meaning users don't need multiple logins, and can instead use a one-stop platform. Government apps should use a government cloud and central authentication services hosted there.
So, not just de-uglifying the UI, but also the UX and login capabilities of multiple applications. I wonder what powered the authoring of the central auth services in Beijing.
I was raised in middle-class suburbia, in the North East U.S. My family wasn't wealthy, but wasn't hurting either. I did well in school, but didn't have to try very hard to maintain grades in Advanced Placement classes. Outside of school, I worked easy lawn-care gigs with my neighbor and we made decent cash with 20-30 hours of work per week.
It afforded me a life of coasting, leisure, and throwing away my downtime.
I am nearing 30 years old and just realizing that I'd consider my behavior to be bad habits I need to kick. I want to work harder, and I have to teach myself what that means.
I would hope that there is some optimal balance. A lot of my childhood was spent doing manual labor for money. A lot of that was wasted opportunity to learn more and get experience that would have benefited me financially later on.
