#ColossalBio keeps on keeping on with their #DeExtinction #DisInformation campaign. Their GMOs aren't #DeExtinct species; they're just making designer transgenic animals. 🦣 🦤🐺 🧟 🧪

GitHub - RILAB/argprep: Snakemake pipeline for generating SINGER input files from whole genome alignment .maf files. Snakemake pipeline for generating SINGER input files from whole genome alignment .maf files. - RILAB/argprep

Recently we're working with SNPs from whole genome assemblies to estimate ARGs. It's a pain to go from alignment files to vcf, keeping track of masked and invariant sites. So we wrote a snakemake/SLURM pipeline. Hope it's useful to others, and don't hesitate to post issues if there are problems!

If the first Lammoth is two years away, that means gene-edited embryos are about to be implanted into surrogates any time now.

I have always argued that the use of elephants in experiments like this is unethical.

My opinion has not changed.

When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Not a new insight, but it's truly something to see how many Westerners have internalised that the people we are supposedly freeing through our imperial warfare don't have to be alive to be free.

Leader of Columbia Brain Institute Quits Over Friendship With Epstein

Gift link from the NYT story about Axel and Epstein. When I was at Columbia he ran a lab where sexual harassment of women was business as usual. We all knew. We all warned each other.

My ethnicity is Black. I capitalize the B because the culture created by my ancestors in the US is monumental in its own right and distinct from other members of a shared diaspora.

Hard pass on twisting those facts into ahistorical talking points indistinguishable from white ethnonationalism.

Opinion | I Just Returned From China. We Are Not Winning.

I wouldn’t put it this way for research, as science isn’t about winning. But I also returned last week from China with similar sentiments about Chinese prowess.

🧵 New preprint! Our 4-lab team evolved Streptococcus pneumoniae in antibiotic-treated mice of varying immune states and discovered something surprising: bacteria rarely evolved resistance. Instead, they found a different way to survive — by rewiring RNA turnover.

Post-Doctoral Research Fellow in Ancient Environmental DNA:Whiteknights Reading UK We are seeking a highly motivated Post-Doctoral Research Fellow to join our research team at Reading, focusing on sedimentary DNA (sedaDNA / environmental DNA) from soils and sediments from the project’s case study regions in Spain and North Africa. You will contribute to the reconstruction of past landscapes and human-environment interactions through the analysis of sedimentary DNA. This includes analysing samples from terraces, irrigated fields and archaeological sites, and using eDNA metagenomics and metabarcoding approaches for multi-species detection, with the aim of characterising changing plant and animal species diversity and richness over time. The position will involve fieldwork, laboratory work, data analysis, and collaboration with an interdisciplinary team of archaeologists, palaeoecologists and historians.

Found out today that an institution where I’m a guest speaker can’t help me with arrangements for accommodations (arrangements, not costs) because I come with my family. Pretty ironic given today we‘re meant to celebrate women in science.

"The academic structure … makes planning for a family feel like an impossible luxury."

In this #ScienceWorkingLife, two postdocs share how, as women in academia, having children can feel impossible—and how talking about it makes them feel less alone. https://scim.ag/46uBWgD #WomenInScienceDay

kind of funny there are prob 1,000 major US musicians and every time conservatives need to put up a music artist to counter a mainstream narrative, they put up kid rock. "ok here's kid rock again" for the next 30 years, an octogenarian man in jean shorts rapping something from the 1990s
