This article leaves me with a lot of questions. As I understand it, SPF labels in the US have to apply to both UVA and UVB. They tried labels specific to each but decided that they were too confusing. Next, you don't need more than about SPF 35 to get appropriate protection from skin cancer. SPF rating higher than that offer only marginally more protection. Lastly, how are these "chemical" sun screens blocking UV. If it's not physically blocking the light, are they somehow changing the spectrum of the light so that it is not harmful? So, other than this guy who has spent $18B to try to sell his product in the US gunning for it, what is the advantage of the newer "chemical"? Do they last longer, cost less, have other functions for health and beauty? Are they generally easier to use?

This just reads like an ad. There doesn't seem to be any journalistic value to this article and it's got a clickbait title. At minimum, it should have noted results for competitors.

Wow! That site sucks on mobile.

Stupid title for an article (duh!) but interesting research. I really think cellular microarchitecture is going to help explain a lot of functions in the body that we currently struggle to understand.

Any ad that starts with TIL or DAE gets an immediate down vote, a cringe, and no further reading

Considering that my wife has a crush on one and abhores the other, I'd say they are different.

I really liked their option to rewrite clickbait headlines. That saved so much time and frustration reading nonsense articles.

They say the same thing about demented old men, so I've given up on thinking that I know what the word "cute" actually means.

I see this in my office constantly and there are lots of reasons surrounding it. All of my patients get a mini mental status exam (MMSE) with their yearly physical after age 65.The ones with any impairment tend to deny it as real. If there is impairment, I try to work it up with labs and then a brain MRI. Insurance won't cover a brain MRI for MCI, so it has to be coded as "memory loss". Memantine and donepizil are not indicated for MCI, just dementia, so we don't prescribe them that early. We wait until it progresses. Also, I've seen a ton of patients over the years who have "microvasular changes" on brain imaging done for other reasons that no one has discussed with them, much less actually done an appropriate cognitive assessment and further workup. I don't know why I am such an outlier in these areas, because I'm not doing things that aren't indicated by specialty recommendation. I think it's just another sign of our broken system.

Thank you for the thorough response. Personally, I would like to reject absolutely everything and then have the website tell me which functionality won't work without a cookie as I try to use it.

Also, what exactly are "essential cookies"? Why does the website get to decide if they are essential?

All I want is for the screen orientation to match my eyes orientation so that it doesn't flip or require me to mess with a toggle when lying down while I read something.
