Pregnancy loss is common in humans, and chromosomal abnormalities are the leading cause. Using genetic data from ~140,000 IVF embryos, we show that maternal variation in meiosis genes influences recombination and aneuploidy risk.

After a long incubation, it is a huge pleasure to finally share the work of @luzmlopez.bsky.social, Jon Harper and their coauthors: "Localised negative feedback shapes genome-wide patterning of meiotic DNA breaks". @gdsc-sussex.bsky.social

I think you are right on the A-DNA...in addition to the tilts, there may well be 11 bases per turn here.
The one thing I *did* check for. And yet still got paranoid...
Is it?! I'm just a lowly molecular biologist looking for a GIF... ๐

Super strong representation from our department in SussexRNA at the RNA UK meeting in Windermere this week.
Many congrats to Jake, Courtney and Hope from the Ben Towler group, and Leandro Castellano, Lidia Vasilieva, Ben and Nikos for having abstracts accepted for presentation. ๐
Beautiful! Is this in real time (20 seconds?)
(Speed also seem to slow over time?)
Changes in the UK R&I funding landscape - doing fewer things better. An open letter from Ian Chapman to research and innovation community:

"Writing papers is rarely (probably never) the rate-limiting step in scientific research"
Important to remember this. However painful writing is, however much more efficient we can make it, for experimental work it's the research that takes the time.

I'm just thankful that I successfully picked a right-handed GIF...๐

Not all great papers take a decade...but some certainly do.
Nevertheless, we'd first need a resourcing model that guaranteed a stable level of research funding per lab...
Still some time to register to this great meeting! Great science and great location for a very affordable registration cost!
Itโs a massive problem across the sector, and Iโm not sure what is the solution isโฆ
Human eggs must segregate their chromosomes with exquisite precision โ yet errors rise with maternal age, causing miscarriage & infertility.
Our new article on @biorxivpreprint.bsky.social shows why chromosome cohesion fails in aging eggs & how to improve it.

Oh - thanks for preparing! It is lovely to see the entire area, and I appreciate the effort!
(I just thought that the final image had been squished, not the source.)
Thanks for sharing these! Unfortunately, I think your final render has been a little squished on the X dimension. It comes out at 2x size as 7856 ร 3712 pixels (= 3928 ร 1856 at 50%, not 4096 x 1856). There is some visible anti-aliasing on the horizontal axis as a result:
Cool - thanks - the vertical size is more than I expected. This means you can look up and down quite a lot? I was thinking that the pitch angle would be more constrained.
Fantastic! Q: How large (in pixels) would the entire rendered viewpoint be (if it were generated as a bitmap)?

Image shows the panels of the final Calvin and Hobbes cartoon, published on December 31st 1995, drawn by comic artist Bill Watterson. It depicts Calvin (a young boy) and Hobbes (a stuffed tiger and his close companion) trekking outside in their winter clothes, across a fresh blanket of snow. Calvin: Wow, it really snowed last night! Isn't it wonderful! Hobbes: Everything familiar has disappeared! The world looks brand-new! Calvin: A new year. ... A fresh clean start! Hobbes: It's like having a big white sheet of paper to draw on! Calvin: A day full of possibilities! The two of them board their sled in anticipation. Calvin: It's a magical world, Hobbes ol' buddy... They set off on the sled out into the snow. Calvin: ... Let's go exploring!
30 years ago today, December 31st 1995, the last ever Calvin & Hobbes comic strip was published. Even now, I still find it so poignant & moving.
SMC and recombination enthusiasts: we updated our work describing the loop extrusion properties of budding yeast condensin and its function in biasing donor usage for mating-type switching. Lots of cool new data, check it out!
