Bee books frequently refer to the two uses of water by bees: cool the hive, and dilute stored honey.
That seems odd to me.
To convert sucrose (C12H22011) to glucose (C6H12O6) and fructose (C6H12O6) means that for every sucrose molecule the bee must find one H2O molecule.
Put another way: C12H22011 + H2O [sucrase] = 2(C6H12O6)
So far I have not found reference to this requirement for metabolic water in the books. Maybe nectar - a very dilute sugar solution - provides all the water the bees need for the sucrase conversion, while water brought into the hive is indeed for cooling and honey dilution.

Oxalic acid is a strong acid which, in solid form or in concentrated solutions, can cause burns of the skin, eyes or mucous membranes; oxalic acid concentrations as low as 5 to 10% are irritating if exposure is prolonged. Human fatalities have been recorded following ingestion of as little as 5 g of oxalic acid. The symptoms appear rapidly and are marked by a shock-like state, collapse and convulsive seizures. Such cases may show marked renal damage with precipitation of calcium oxalate in the renal tubules. The convulsive seizures are thought to be the result of hypocalcaemia. Chronic skin exposure to solutions of oxalic acid or potassium oxalate have been reported to have caused a localized pain and cyanosis in the fingers or even gangrenous changes. This is apparently due to a localized absorption of the oxalic acid and a resultant arteritis. Chronic systemic injury from inhalation of oxalic acid dust appears to be very rare, although the literature describes the case of a man who had been exposed to hot oxalic acid vapours (probably containing an aerosol of oxalic acid) with generalized symptoms of weight loss and chronic inflammation of the upper respiratory tract. Because of the strongly acid nature of the dust of oxalic acid, exposure must be carefully controlled and work area concentrations held within acceptable health limits.

Viktor looks like a nice chap, and he's brainy, too: "Viktor has spent his life working with bees. As a small boy growing up in Ukraine he learnt from his father how not to be a bad beekeeper and went on to take a degree in Zoology and Animal Science at Kiev University."
Anyway, "Viktor & The Honeymakers" would make a great band name...

Even though a kind of spring has arrived in the UK, I am concerned even as the weather turns warm enough for the bees to fly and the queens to lay. Blackthorn (Prunus spinosa) has blossomed and Hawthorn (Crataegus spp) will follow soon, and there are some daffs and jonquils (Narcissus spp) - but in my bones I am not convinced that there is enough forage for the expanding nest.
All my hives have fondant packs, as insurance...

The scheme's goal is to have trained 50 women within the next five years, as well as building 2,500 hives in 25 Unesco biosphere reserves, and restocking 125 million bees.
So, ten beekeepers per year. Crikey.

The colonies continue to eat fondant like no tomorrow. In the past the bees have largely ignored fondant, and been happy to forage instead. This year each colony (in National hives) is consuming approximately 500g fondant per week. According to some beekeepers, this is a sign that I did not feed the bees sufficiently going into winter. The alternative explanation is that I removed too much honey going into winter, as I would rather they used their own stores - and presumably that is better for them, too.

Great presentation by Celia Rudland of East Surrey Bees about preparing for Spring. With more than 200 colonies, she really knows how to put theory into practice.
In the past I have bought both queens and colonies from East Surrey Bees, all of which have proved excellent.

When Jessye Norman was attempting and failing to squeeze through a narrow doorway, a bystander helpfully suggested, "Try sideways," to which she is alleged to have replied, "Honey, I ain't got no sideways!" (Ms Norman sued for libel, unsuccessfully, twice, about the reported remark.)

Honey bees lose sleep after ingesting pesticides, leading to greater stress and lower hive survival rates
What baffles me is how the researcher actually completed her research. In my beekeeping year, if I don't kill 'em it's a result, let alone figure out their sleep patterns.

In summary, the European Honeybee is not native to North America, and rising numbers may threaten survival of local bee species. Nicely written piece here: https://www.wired.com/story/why-some-ecologists-worry-about-rooftop-honey-bee-programs/

"In some places, such as London, so many people have established urban hives that the honey bee populations are threatening other bee species. Increasing evidence shows that there is insufficient forage to support current beehive numbers in London (see Figure 3). This is a problem for bee conservation, as honey bees outcompete wild bees by monopolising floral resources. Moreover, some reports suggest honey bees can transmit diseases to other wild species. So, beekeeping to save bees could actually be having the opposite effect."
