One of my first uses of this site, in 2013, was to live-tweet my re-read of Jurassic Park. In the story, a greedy tycoon bites off more than he can chew in a business venture and accidentally turns it into a living nightmare. Have we come full circle?

You know it's getting real when university admin gets involved.

Synapsids (🦣) and sauropsids (🐦) have been at war over planetary dominance for >300 million years. 🦣got an early lead in the Permian, then🐦famously ruled the Mesozoic.🦣took over again after the K-T extinction. Today many species of both🐦&🦣are endangered. What happens next?

I guess that sink at twitter headquarters was meant in the "source–sink dynamics" sense

@MNithyassree @S__Baksh That would make sense, but unfortunately nothing in immunology makes sense. The B stands for Bursa.

We are searching for a Genomics Technology Transfer Specialist to help support malaria molecular surveillance at partner laboratories in South America. Please reach out to me directly if you fit the profile and will be at #ASTMH2022! https://t.co/lEiYSK1TPM

Covid has killed so many more than, say, Ebola, in part because it’s not scary enough: folks didn’t take it seriously since it’s largely survivable, hence the huge death toll. I think of this when people point out that climate change is more survivable than, say, nuclear war.

[Jacob A Tennessen @JacobPhD]

Going to my first in-person conference (ASTMH) since 2019. To the best of my knowledge I’ve still never had covid. Wish me luck.

Sea cucumber or microbe?

This is fine

Reviewer: The methods are logically flawed and Figure 1 is not supported by the data; units are wrong on line 108
Author: *fixes methods and removes figure, making the next figure into Figure 1, line 108 is now a lit review*
Reader of transparent reviews: Huh?

[Jacob A Tennessen @JacobPhD]

Has anyone ever read the "transparent" peer reviews published alongside a paper (which refer to an earlier draft of the manuscript and thus are presumably largely unintelligible)? Why?

@PhD_Genie We’re technically co-first authors but she did most of the work

So @AdamRutherford is receiving a lot of skepticism about his tweet saying that if Cheddar Man has any genealogical ancestors today, he is the common ancestor of all present-day humans. Adam is correct about this — I think this is such a cool finding, so I'll explain it below.

[Jacob A Tennessen @JacobPhD]

@JamesWorron @AdamRutherford If you know of peer-reviewed modeling work or population genetics, or statements by population biologists, that cast doubt on the model I'd be happy to take a look.

[Jacob A Tennessen @JacobPhD]

@JamesWorron @AdamRutherford B/c it's often easier to spread sperm than germs (which require certain human population densities, animal vectors, etc. or they peter out). And small numbers of migrants don't substantially change the genetic makeup of a population, & in the absence of selection immunity wanes.

[Jacob A Tennessen @JacobPhD]

@JamesWorron @AdamRutherford Not sure if you're suggesting that the germs should have already been in e.g. the Americas, or just the genetic immunity to those germs. Either way, why weren't European descendants of East Asians (e.g. Genghis Khan) immune to the Black Death, also from East Asia?
