How do they separate the genders?
For small scale production it's a manual process (size differences), for industrial scale it's using ML and blowing air in a certain direction. Basically the mosquitoes are brought under a camera in some form of tube, and depending on the gender they are blown into a certain direction separating male and female. I don't think this is part of Verily, and afaik Verily was one of the first that starting doing this.

#32I've had dengue fever. There are a few different strains and I had one of the milder ones but it was still enough to put me in the hospital for dehydration as an otherwise healthy 20yo. In Thai it's known as hemorrhagic fever, but unlike in English, where "hemorrhagic" is a technical term where the meaning isn't clear or is softened, in Thai it's just three simple Thai words: ไข้เลือดออก, "fever [that makes] blood [c…

Fair enough. I did that because the grammars of Thai and English are quite different, in noun-modifier order, distinction between verbs and adjectives, and verb conjugation (those are just the relevant differences here). I could have said "blood-exiting fever" but that changes the word order.
Anyway, I don't speak Thai, so it's very probable that I cannot appreciate this quality even if you tried to explain it a thousand time.

#34"in rare cases" My mom nearly died to Dengue fever. Twice. This shit is incredibly dangerous.
Dengue is odd in that surviving an attack of one strain makes you immune to that strain, but increases the odds of getting severe complications if you catch one of the other ones. Which is which dengue vaccine is only recommended for people who have already had it once!

It's an extra-lame counterpoint because male mosquitos don't bite, and they're only releasing males.
It's lame but it's true that during the Verily release of mosquitoes from their carts [1] in HDB estates, they had a lot of people complain how since releasing they saw more mosquitoes and were bitten more often, while the mosquito traps showed a clear decline in population.

For the counter-point to be meaningful, people would have to individually kill a lot of mosquitoes. Made me wonder, what fraction of mosquitoes are killed by humans in a city setting? I'd guess it's very small. 1/1000? Has anyone tried to measure this?
Direct kills are probably pretty marginal, but Singapore employs insecticides in prodigious quantities. It's almost eerie how eg hawker centres have no flies and outdoor gardens are almost entirely devoid of insects (whereas if you cross the border to Malaysia, both can be found in abundance).
I am intrigued. Do you have a reference for that?

I believe there's very little agriculture in Singapore - almost all food is imported.
Singapore has some limited 'agriculture' (and a big shift to industrialised hydroponics and stuff); but most is outside the city. It's indeed quite scary how much pesticides are currently used and how a lot of the green patches and parks have little flies, butterflies, and other insects.
I am curious. Do you have a reference for that?
