>The boundary between them is thought to terminate at a "second critical point." This deeply supercooled region is so hard to study experimentally because water crystallizes rapidly

This sounds like the type of thing that could be used for some future technology that doesn’t exist yet and I can’t comprehend. Some sort of process that takes advantage of being in this second critical state.

So the OTA firmware updates on my dehumidifier for when they discover a new kind of water will come in handy after all!

Nah, IFIFY: So the OTA firmware updates on my dehumidifier is for when they make a new kind of dehumidifier that they want me to buy!

It would be hilarious if homeopathy turned out to be right!

(To be clear, I don't think that will actually happen, but it would be hilarious if it did!)

Homeopathic medicine is already recommended by 1 out of 1000000000000000000 doctors.

There is no basis to suggest that any product uses this property of water. As for homeopathy, it isn't one thing. The effects, if any, can vary greatly by the substance and the concentration. Some low-dilution products work and many high-dilution products don't. There is such a thing as excessive dilution. Anyone who is painting a simpler picture of it is almost certainly wrong.

Somewhat related is the hydration shell around molecules especially proteins. It’s been shown that semi structured water around proteins help guide molecules to reaction sites. Water is an amazing thing!

Careful! Talking about a naturally occurring binary is going to attract the attention of Critical Theory believers!

Before you know it they are going to use the Power of Discourse(tm) to gin up a whole new discipline devoted to advocating for the idea that water molecules exist on a spectrum…

Sadly paper is behind paywall. But I question the choosing of the water model to be a 4-site, and why that specific 4-site one (TIP4P) instead of others that have shown to be more accurate such as OPC. Also, there seem to be previous experimental work (https://arxiv.org/abs/1304.2877) showing some evidence that apparently is not even referenced in this new paper. I wonder how does that compare, if at all.

So if liquid water is really a mixture of water and water, is it safe to say that this paper establishes that water is wet?
