Mice smoke?

  > "Mice smoke?"
The experiment summary:

  > "The team bred four strains of mice.
  >  They then exposed the mice to a single dose of the liver carcinogen diethylnitrosamine (DEN).
  >  DEN is found in tobacco smoke."
They simulated the "consequences" of smoking in mice.
htek•27m ago
Mice are used for inhalation and skin studies because they're cheap, we know their genome, they have a short lifespan for whole lifecycle observation and they're ideal for mapping to human respiratory and skin responses.

These comments are filled with people who believe that everyone else here is dumber than they are. Leaving shallow dismissive comments explaining something that doesn't need to be explained is like crack to them.
manarth•9m ago
It's a bit more than that.

The migration from mouse models to human understanding is long and complex, and although it's a meme, "in mice" is a good shortcut for saying "This is a good start, but it's not ready to extrapolate into conclusions against the impact to human beings".

Anecdotally, whenever I go swimming with my kids in the summer, and I don't put sunscreen on right away, but let myself get some intense direct sun, I feel good and sleep really well that night.

As long as I don't let myself get in a red, sunburn situation.

Vitamin D deficiency
GlickWick•30m ago
Definitely not. Vitamin D takes a while to synthesize and build up. A quick fix like this isn't possible.
bob1029•28m ago
I can spend a solid hour in the sun before I start to burn, assuming I have a hat on my head.

I've also noticed some correlation between my diet and how fast I burn. Whenever my metabolism is running at/near ketogenesis, it seems like it takes a lot longer for the sun to affect me.

Ralfp•21m ago
Yes, some stuff make your skin more sensitive to light than others. For example, you should avoid vitamin A creams and some herbs during summer because they increase risk of permanent skin discoloration.
pazimzadeh•18m ago
Which herbs
doctoboggan•31m ago
Isn't this sort of like asking "Why does getting shot kill some but not other?" It depends on which part of the body was shot, and which part of the DNA was damaged.
Noaidi•28m ago
No. Genetics and nutrition make a big difference here. It is like one person is wearing a bullet proof vest and both were shot in the same place.
mr_mitm•24m ago
The way I read the article was that cancer is caused by deficiencies in the body's repair mechanism. It appears as if some have a more robust mechanism than others, depending on genetics.
dyauspitr•17m ago
My mom had 14 siblings and only one of them got breast cancer (she was a nun and never breastfed which drastically increases a woman’s odds of breast cancer). But prior to that, her mother’s family, which was also large never had a case of cancer. My mom’s siblings also had around 30 kids between them some now in their 60s. There hasn’t been a single case of cancer amongst the kids either. So it’s something like 150 people with only one instance of cancer over the last 3 generations. There is definitely a strong genetic component to this.
coolThingsFirst•30m ago
Even if smoking didnt cause cancer it would still be terrible.

6 months since i quit using nic gums.

Noaidi•29m ago
This is why Zinc is needed to prevent cancer[1].

The gene they are focusing on in the study [2] is Methylated-DNA--protein-cysteine methyltransferase (MGMT) and it needs zinc as a cofactor [3].

Not enough zinc, lower MGMT, and less DNA protection and repair.

Nutritional deficiencies and genetic differences increase the risk of cancer.

SketchySeaBeast•8m ago
That would imply that red meat eaters would be less likely to get cancer which doesn't seem to be the case. I'm not saying that zinc isn't a factor, but I think that saying "Zinc is needed to prevent cancer" without nuance is irresponsible. We should be so lucky that we can narrow it down to a single dietary element or be able to blame it simply upon nutrition.

I've only ever smoked like a quarter of one cigarette when I was eighteen and I thought it was fucking gross so I never picked up the habit (fortunately).

That said, I'm a pretty pale dude and my sister has gotten skin cancer twice now [1], so I've started getting a bit worried that that's going to happen to me. I've started wearing a baseball cap every time I go outside to protect my scalp (since my body has decided I don't need nearly as much hair anymore), I almost never go outside without jeans and often now a hoodie even when it's relatively warm outside. If I think I'm going to be outside for more than ~30 minutes, I wear sunscreen on the exposed parts.

I have to admit, that I kind of hate it. I don't like the slimy feeling of sunscreen on my skin, I don't really like how hats feel on my head, and of course wearing a lot of clothes when it's warm outside isn't terribly comfortable.

[1] Fortunately caught very early since she gets frequent checks, so she's fine.

pilgrim0•12m ago
Also share the icky for greasy sunscreen. But there are some with a matte dry texture that not only serves the purpose but also make your skin looks nicer, since it levels out those small color variations. It’s a big market, so they really do research on those things.
itsmartapuntocm•10m ago
A fairly bad sunburn was the reality check I needed to start scheduling annual screenings. 30 minutes or so a year for peace of mind.
Mezzie•9m ago
Strong recommend a UV umbrella. I also hate the feeling of sunscreen and will also fry the minute I so much as look at the sun.

Also, linen clothing. Far more comfortable in heat while keeping you covered. Hoodies and jeans sounds miserable.

IshKebab•6m ago
Just so you know, burning & cancer isn't the only reason to avoid strong sunlight - it also causes skin aging (i.e. wrinkles). If you don't want to be super wrinkly when you're old, wear suncream!
krrrh•21m ago
The number one reason I wear an Apple Watch all summer is the UV index complication. If the number is at 4 and trending down I let the kids run free.
pazimzadeh•18m ago
Interestingly the best time to go out is at solar noon, when the UVB/UVA ratio is higher. Just go for a shorter amount of time to compensate for the higher overall intensity.
Rnonymous•7m ago
Care to explain? Isn't UVB more harmful than UVA?
tartoran•6m ago
That's only if you don't have a lot of time out. If you're planning to be out for a while I'd avoid being too exposed during the 12-3 window.
brightball•9m ago
I typically do the same thing. I only wear sunscreen if I am planning on being in direct sun for an extended period of time where I can't easily get back in the shade.

The more you're able to build up a base tan the less you need it too.

JoshGlazebrook•7m ago
So we're just out here perpetuating myths on here now as well?
brightball•6m ago
Correction - The less you need it to avoid a burn.
leawi•8m ago
A bit offtopic, but have you tried different sunscreen types? There are quite a lot of formulations from matte creams to solid sticks. Mentioned because I remember avoiding sunscreens precisely because of that slimy feeling I got from the drugstore ones, that is, until I found an "invisible" one that doesn't feel like anything at all on my skin.
tombert•6m ago
I have not. Do you have any recommendations for specific brands? I'll order a bottle and try it out.
brightball•7m ago
Sun shirts are a great option for me at least.
thisoneisreal•6m ago
Check out mineral based sunscreens, I have sensitive skin and I find them infinitely more tolerable.
