East Coast US indigenous people "probably" had direct contact with southwest indigenous people 4k years ago. It's really cool to see this proven, but by now we really should assume that people traveled unless proven otherwise. sciencenews.org/article/island…
Something that regularly frustrates me is the assumption that ancient people didn't travel/trade. It's not just a cultural thing, it's biology. Humans evolved as exhaustion hunters. Long, steady, unaided distance travel is literally in our DNA.
To assume that ancient humans didn't use that skill to travel, explore, and communicate with other humans is silly. Even moreso in the face of ever growing evidence that basically every ancient group did.

Lots of layers here.

First, big labs =/ small labs. Structurally, they're very different in PI interaction.

Second, cascading mentorship is critical. As a student, being a PI is still a long way off, post-doc is your next step so that's critical mentorship.
Third, personally, mentorship from the PI in two labs kept me in science for nearly 20 years, and "mentorship" from the PI in another lab almost drove me from science completely, and did drive me from academic research.

But I've worked primarily in small labs
and as I noted above, small labs are very different. In a small lab as a summer high school intern I had daily meetings with the PI and active input on the project. In a big lab, you'd be working almost entirely with a grad student or post-doc, seeing the PI for project updates.

As a biologist and someone who drank our own raw goatmilk for years growing up...

OMG THIS. If you are not intimately familiar with where it's been and how it's been handled DO NOT BUY RAW MILK.
And by "intimately familiar" I mean, really intimately. It is a risk. It's a risk we chose to take knowing exactly how everything was handled and with mitigation on our part. But even so it was STILL a risk.
Buying raw milk puts the decisions on mitigation in someone else's hands, while you continue to carry the risk.

So much to unpack in this article. First, and most important, the lesson science has to KEEP learning, that you get crap data if you only look at one population in one area.

The second is that however you raise your baby, they will catch up.

sciencenews.org/article/cultur…
Beyond that, there's the broader science. A confirmation of the walking->talking developmental jump, a proposal that even non-walking babies can learn restraint...
Not only do we get crap data when study a narrow sample, we get really NEAT data with WAY more information when we study broader groups and include things like other locations, cultures, etc.

Thread about causes of the trans trend other than "homophobes trying to get rid of gay and lesbian youth!" that are underdiscussed because they are inconvenient to the lesbian and gay community, and to the general lefty and feminist crowd. Buckle up, here we go.
When you decided that being straight meant being a "breeder," girls who don't want to be seen as broodmares or confined to traditional roles were listening. However some of those girls also desire to be in a relationship with the opposite sex. How to reconcile these things?
When you decided to make yourselves feel cool by declaring that straights were boring, khaki-wearing suburbanites who have boring sex lives and lack creativity, fire, and verve, kids were paying attention. Who wants to be "vanilla" when it is increasingly disdained?

Here we go again. #startoftheline #summeroftrains2019 #es9150
You can find my journeys by train in Europe earlier this year here. #springoftrains

You've got to hand it to Eurostar: it takes a lot of self confidence and optimism to claim you have WiFi time and time again despite all evidence to the contrary. We could all learn a thing or two

(My first tweet was initially sent in London. It didn't make it up until Calais!)

(1/5 ish) I missed this tweet yesterday, but thankfully it showed up in my feed today thanks to a retweet from @financequant . The topic of the paper is the question a options trader friend asked me for help on 20+ years ago. It is amazingly cool to see the problem solved.
2/5 the conversation 20+ years ago started with my friend asking me to write code for some of the ideas in this book
(3/5) Peters' book was my introduction to finance and both the math and the ideas in the book were fascinating. I'd spend the next 4 years studying those ideas in my spare time. While doing that I encountered this paper from Zvi Bodie that was also very influential to me. +

#Khashoggi Case Thread: I am going to ‘pin’ this post to use it as an ‘Info Thread’ on the #Khashoggi Case. I am in #Turkey. I’ve been following the case closely and with access to sources & experts here. This is a very ‘sensitive’ criminal case due to ‘Diplomatic Booby Traps’!!!
The Evidence Obtained Outside Cameras will not show any evidence of ‘tempering’ but other than license plates of dozens of diplomatic cars (Many with tinted windows-large trunks) with related time stamp, drivers Info, model/year: Nothing.
#Turkish Intel-Investigative Bodies also have the list of all Diplomatic & Private Saudi & “other significant’ Planes in #Turkey for the period of ‘interest.’ Many of the Target airports have their own security cameras & related evidence.

So I have a ton of series I’m behind on, and many more I haven’t even started. BUT, I also have this. I’m gonna do a rewatch thread instead~ I’ve seen this show many times, but the last time I got all the way through it was probably more than a decade ago. So let’s do this! 🦄
First, to set the mood: The opening. a classic. Admire Miki's floofy clothes~
Admire Miki's willingness to shill the official MB goods right away in the OP
