    They use adiabatic coolers to minimize electrical cost for cooling and maximize cooling capacity. The water isn't directly used as the cooling fluid. It's just used to provide evaporative cooling to boost the efficiency of a conventional refrigeration system. I also suspect that many of them are starting to switch to CO2 based refrigeration systems which heavily benefit from adiabatic gas coolers due to the low critical temp of CO2. Without an adiabatic cooler the efficiency of a CO2 based system starts dropping heavily when the ambient temp gets much above 80F. They could acheive the same results without using water, however their refrigeration systems would need larger gas coolers which would increase their electricity usage.

    the US the 50 states basically act like they are different countries instead of different states. There's a lot of back and forth on that - through the last 50+ years the US federal government has done a lot to unify and centralize control. Visible things like the highway and air traffic systems, civil rights, federal funding of education and other programs which means the states either comply with federal "guidance" or they lose that (significant) money while still paying the same taxes... making more informed decisions and realise that often the mom and pop store option is cheaper in the long run. Informed, long run decisions don't seem to be a common practice in the US, especially in rural areas. we had a store (the Jumbo) which used to not have discounts, but saw less people buying from them that they changed it so now they are offering discounts again. In order for that to happen the Jumbo needs competition. In rural US areas that doesn't usually exist. There are examples of rural Florida WalMarts charging over double for products in their rural stores as compared to their stores in the cities 50 miles away - where they have competition. So, rural people have a choice: drive 100 miles for 50% off their purchases, or save the travel expense and get it at the local store. Transparently showing their strategy: the bigger ticket items that would be worth the trip into the city to save the margin are much closer in pricing. retro gaming community GameStop died here not long ago. I never saw the appeal in the first place: high prices to buy, insultingly low prices to sell, and they didn't really support older consoles/platforms - focusing always on the newer ones.

    Bit misleading. Tumour-associated antigens can very easily be detected very early. Problem is, these are only associated with cancer, and provide a very high rate of false positives They're better used as a stepping stone for further testing, or just seeing how advanced a cancer is That is to say, I'm assuming that's what this is about, as i didnt rwad the article. It's the first thing I thought of when I heard "cancer in bloodstream", as the other options tend to be a bit more bleak Edit: they're talking about cancer "shedding genetic material", which I hate how general they're being. Probably talking about proto oncogenes from dead tumour debris, but seems different to what I was expecting

    Hear me out, Eliza. It'll be equally useless and for orders of magnitude less cost. And no one will mistakenly or fraudulently call it AI.
