This is not a CT but a PET scan, it records passive radiation from a molecule injected into the body, and therefore a 10 min long scan. Then it is based on radioactive carbon (C-11), which is pretty uncommon and needs quick use after production, so not every PET(CT) can do that, it needs be in the vicinity of a production facility (i.e. close to a university/research hospital). This is the sense of the last sentence: it needs a replacement the carbon with another radioactive isotope (fluor for instance) to be doable at every PET/CT place. I don't blame the title here, because the article itself is very strangely written, it says as well "CT scan" but this is no "CT scan", this is a PET scan.

Right, but it's a weird terminology subject, because CT is just short for "Computerized Tomography", with the initial implied "X-ray" part being a convention -- but all of these 3D scan techniques are variant kinds of Tomography, with X-ray CT/CAT scans being the original kind.

Your comments about C-11 are well-taken and an important caveat.

That's interesting, thanks for sharing. I was aware of the more common "radioactive glucose" PET scan that helps pinpoint cancer...where fast reproducing cells consume glucose. Didn't know there were adjacent types of PET scans.

basically, author expects calibrated minimal services, good support, and a minimal standard of quality. This is what you call a classic hotel/lodge. I fully agree with you, and those living close to these miserable BnB businesses surely would agree as well. This "model" is rotting city centers and popular places. AirBnB will never care about that poor lady. AirBnB will know how to make her anger disappear into the zero-star reviews statistics - it is much more important to keep a large density of cheap appts in the center of Lisbon.

There's no good reason AirBnb could not offer proper support. Showing contempt for your customers like this is a choice.

Might you tell us about any large, modern, fast-growing businesses which happily limit profits, so they can pay for high-quality customer support? Yes, it's "a choice". Sadly, it's an overwhelmingly popular choice.

And it's a popular choice because the consumers often don't seem to care. Many are willing to accept poor customer service in the pursuit of lower prices for goods and services.

My employer chooses to staff our customer support lines with North American agents who know what they are doing.

> any large, modern, fast-growing businesses which happily limit profits, so they can pay for high-quality customer support?

Famously, Chewy. Amazon (used to?) have a reputation for being very pro consumer. Zappos.

Obviously, those are all companies that grew because if I knew of fast growing businesses that were sustainable and likely to succeed I would be investing other people's money fulltime.

Zappos, from inception to 1B acquisition and beyond.

Although I would argue that Zappos didn't "limit profits." Rather they (correctly) surmised that the only way to successfully sell shoes online as a core business was to be seen as bending over backwards from a customer service perspective.

Which is not to take anything away from them but customer service is pretty much baked into their model.

There is a very good reason: their business model. They absolutely do not want to be in the business of verifying and maintaining their listings.

I don’t know why I’ve had such a different experience to others, but in both cases where I complained to Airbnb when a host was unable or unwilling to offer a resolution, Airbnb made things right for me - in one case even covering the parking ticket I’d ended up with from the host’s crappy instructions, in the other, the listing was removed as the issues were too egregious to number.

And to take immediate actions. As they claim somewhere to have already recovered 10 M€ in taxes, having only scanned parts of the french territory. And how clever to make this campaign now, who is sad about those caught after this summer drought where water was missing everywhere.

It appears to be on mice only in the 5th paragraph, and the sole photo is of a patient (before it is said to be on mice). Sarcasm/negativity is a normal reaction when you spot an ad for a local university with a random research with especially touches most of us. It is not so hard to be honest and support honest research and these respectable advances without such tricks.

iMessage is iOS right? because the link you post shows facebook messenger is strongest in the US.

That diagram is for Android only, so I wouldn't read too much into it.

You simply stated it better than the Reuters article. Those paintings and the rests of food in the jars make it really exceptional. There were already many food stands you could see in Pompei (or Ercolano) nearby.

3d image description saying it is from Lombardy, "France" is a strange mistake in an otherwise well documented article.

you are very correct - authors are doing a fascinating and smart parallel, but the analogy (contrast X-RAY imaging) is wrong. A radioactive element (F-18) marking a glucose molecule for tracking sugar metabolism in the human body with an imager (PET) is what they mean. This is one of many techniques in the field of nuclear medicine or molecular imaging.
