Reply to New find of Stone Age tools dated 300k years earlier than previously thought, 2.9 million years ago, along with butchered hippos and human-like ancestors by qartas
Fascinating article! Different species yet had the same inspiration to make stone tools.
>That means they would have eaten the flesh raw or pounded it into a fine mush, a la hippo tartare.
That sounds like a classy meal!

You've had continuous lower extremity fractures for 25 years?

There aren't all that many fish & chip shops in London or the UK. You could easily spend a week in central London and not see any of them. I'd definitely avoid fried food in any pubs though, as they often share a deep fat fryer.

This study is in line with previous studies comparing aspirin to LMWH in this specific population of orthopedic trauma.
This was a larger number enrolled and showed low dose aspirin is non-inferior to LMWH for all cause mortality. But LMWH had lower instances of DVT and PE.

Reply to comment by inyourgenes in People from the poorest backgrounds are far more likely to develop a mental disorder later in life than those from wealthier beginnings. More than half of people with a low educational attainment at age 30 will have a diagnosis of a mental disorder 22 years later by Wagamaga
>The opposite actually - the genetic predisposition for mental illness can’t weed itself out of the population unless it onsets before being passed on
This is a restating of my point; I'm not sure why you're suggesting I said the opposite. Please re-read my comment in context.
If the illness does not affect mating, i.e. manifests AFTER breeding, it will not be selected out. The illness has to manifest or become apparent early enough to impact mate selection or reproductive fitness to be selected against.

Just different disorders - the ones which are useful to economic function aren't diagnosed / named where those which aren't are.
Who decides this distinction?

eliquis isn't typically used for DVT prophylaxis, but rather in those who have a known DVT/PE or in those with risk of stroke for AF, as two common examples.
a better question would be if asa could prevent DVTs in the general hospital population, and not simply young healthy trauma patients

What does healthy or unhealthy mean in this regard? The researchers made sure that the participants were a randomized group of people in a CR and with all of their nutrients met. So that points to a really strong association between CR and this slowing in aging. Thats all this study was saying really. Of course there are various factors that go into good health and now we have potentially found an additional factor, which is why I'm suprised by your opposition to it.

Reply to comment by rubixd in Researchers find that outdoor cannabis can "express more cannabinoids with potentially desirable bioactivity" compared to cannabis cultivated indoors under artificial lights. by OregonTripleBeam
This study didn’t even bother controlling one of the few variables they could and that make a massive difference. The soil media is completely different indoor vs outdoor. That’s not a minor fuckup. There’s really no justification not to control for that. Give both plants the same soil composition.
The title is misleading without mentioning that. It’s like studying how different types of exercises lead to more or less muscle mass gain among two groups, but forgetting to mention group A gets workout supplements and group B ate only potatoes the whole time. Bad science.

The scientific community has known for decades that calorie restriction increases longevity in mammals, but the exact mechanisms weren't well understood. It seems like we might be narrowing down the way it works.

Fortunately destruction by combustion is an effective measure of control.

My apologies, I used the wrong word. I have that problem. I meant heparin.
Will edit to correct.

This study was not comparing warfarin and aspirin. It was comparing low molecular weight heparin (lwmh) and aspirin. Lwmh is not the same thing as warfarin.

Warfarin is a different type of blood thinner from aspirin and works in different ways.
This study was researching what, if any, difference there was for patients with a specific ailment. "Is one better than the other and, if so, why?"
They found out that for this particular ailment, no, warfarin wasn't better. That was something they didn't know before.
But for some ailments warfarin is better. And studies like this one are why we know that.
Edit: I said warfarin when I mean to say heparin. My bad. I have a problem with mixing up words when I speak or write. I usually proofread better. Apologies.

It's pretty universal. I'm sure some adjustments meed to be made for people who weigh like 600lbs, but for pretty much everyone else 81mgs is sufficient.
My mom is on Aspirin, Elliquis, and Warfarin for her heart problems because simply adding more aspirin or increasing either of the other drugs doesn't do enough. Most drugs reach a maximum effective level and after that more of the drug doesn't have any more effect. That's why people with serious problems will be on so many different medications instead of just taking a huge dose of one drug.
And in most cases, body weight is irrelevant. Certain drugs, yes, body weight matters. That's true of anesthetics and a few other types of drugs. But for most of them weight doesn't matter.

350 lbs is pretty big for a linebacker, these guys would be better as OTs or maybe NTs

Yeah, this.
There's one main difference to inside and outside light, and that's UV. I would argue that a change in grow medium and style has a larger effect than simply the added UV exposure from the sun.

It took me a few years to be able to stretch my arm to where my hand can reach any part of my back easily now. It started with applying self tanner and needing to put it on my back myself.
So little by little everyday I would stretch my arm further up and after awhile could turn my arm around, reach behind my back, and touch the back of my neck all the way up. It comes in handy!
