MAJOR UPDATE: All planetary boundaries are assessed, and six are crossed. For the first time ever, scientists have quantified all nine planetary boundaries. Six of them are already transgressed and we are increasing pressure on the others. Read more: buff.ly/45Ps1QG

Sono incredula di fronte alla vicenda che ha coinvolto Sofia Pasotto, giovane attivista di @fffitalia, fermata, identificata e trattenuta dalla questura di Mantova durante il Festival della Letteratura solo per aver portato con sé dei cartelli critici nei confronti di ENI, 👇

This past spring semester, while my AMAZING PI, Emilia (@emiliahsc), has been on sabbatical, I had the exciting opportunity to serve as instructor of record for her computational population genetics course. The entire course is publicly available on GitHub github.com/David-Peede/BIOL1…

Just read the paper and I agree with you. On real data (Fig. 3), only their method FitCoal infers a bottleneck at 900kya but on simulated data (Fig. 4), PSMC and SMC++ can recover the bottleneck, much deeper than the constant-sized part.

🚨New #ancientDNA data from #Africa🚨 and the first from the medieval #Swahili coast! Among the most amazing results are different participation from males/females in pop. mixtures (e.g. male Near Eastern & Persian ancestry mixing with female African ancestry).

Estimating the genome-wide mutation rate from thousands of unrelated individuals

We provide a method for estimating the genome-wide mutation rate from sequence data on unrelated individuals by using segments of identity by descent (IBD). The length of an IBD segment indicates the...

Updated preprint on our Coalescent-HMM method to infer population size history: doi.org/10.1101/2021.05.22.4… We extended the composite likelihood, did more some more simulations to understand how it behaves, and included some analysis of human data.

It is not even about the legitimacy of the question. And perhaps not even of scientific accuracy. But the sensationalism and offensive undertones of such rants is pretty appalling. Love the killer single-line thoughts of the 'traditionalists' though.

Our paper on the Grotte Mandrin (France), is out. We show that Homo sapiens made the so-called "Neronian" Palaeolithic industry there ~54,000 years ago. This is the earliest evidence we have in this part of the world for modern humans. advances.sciencemag.org/

(1) Interesting new paper. Slimak et al report on the site of Grotte Mandrin in southern France. The authors claim the site shows Homo sapiens in western Europe thousands of years earlier than previously thought (ca. 57-52,000 years ago). My thoughts... science.org/doi/10.1126/scia…

Modern humans first arrived into Europe in Mediterranean France 54,000 years ago but were subsequently replaced by Neanderthals.

Ever wonder what the #3Dgenome folding🔺of a Neanderthal looked like?! Could it hold any clues as to where and why we have DNA 🧬and trait differences? Check out our @capra_lab, Pollard lab & @gfudenberg lab collaboration @biorxivpreprint biorxiv.org/content/10.1101/… 1/8

In humans and other mammals, germline mutations are more likely to arise in fathers than in mothers. Although this sex bias has long been attributed to DNA replication errors in spermatogenesis,...
