Bird eggs with different sizes, colors, patterns and shapes.
Not all #eggs are the same: birds‘ eggs have an incredible range of different sizes, colors, patterns and shapes. 🪺 🤩 Happy #Easter, everyone!
NASA just dropped this image of Artemis II astronaut Christina Koch looking back at us. The first woman to ever see our planet in its entirety. I’m not crying you’re crying 🥹🔭🧪 📸: NASA
🎉 Congrats to 2026 Thomas Hunt Morgan Medal recipient Judith Kimble of @uwbiochem.bsky.social! Her work has built an entire field and inspired generations of scientists through her mentorship and leadership.

Meiosis faces a fundamental problem:
It must repair hundreds of DNA double-strand breaks while executing a transcriptional programme essential for gamete development.
But many of these breaks occur in genes.
So how are these two processes reconciled?

Want to know how histone marks regulate your favorite gene? Go single molecule with ChromSMF: integrated measure of chromatin accessibility and histone marks + DNA methylation, TF footprints and genotype for free! Very proud of @mpalamin.bsky.social ! @embl.org
Recently amplified gene arrays are a super interesting phenomenon, but many still resist our attempts to assemble them. @dantipov.bsky.social has developed a new method (Trivial Tangle Traverser) that resolves assembly graph tangles caused by such sequences (1/4) www.biorxiv.org/content/10.6...
Microscopic view of a glowing, irregularly shaped primordial germ cell with long protrusions with purple and green fluorescence against a dark blue background.
How do primordial germ cells (PGCs) migrate across a developing embryo?
#LMBResearch from Katharine Goodwin and Kate McDole (@cellbiol-mrclmb.bsky.social) uncovers the mechanisms PGCs use in mouse embryos to navigate this long and surprisingly risky journey.

AlphaFold database has entered the era of complexes. Together with NVIDIA, DeepMind and EBI, we use ColabFold, OpenFold and MMseqs2-GPU to predict ~31 million complexes (homo & hetro-dimers) resulting in 1.8 million high-quality predictions

This is kinda bonkers.
In addition, 20 amino acids were found on Ryugu, along with uracil and vitamin B3. These have been found in other instances, but since the samples from Ryugu were collected directly from the asteroid and delivered in sealed capsules, contamination on Earth could be ruled out.
Deep coverage and extended sequence reads obtained with a single archaeal protease expedite de novo protein sequencing by mass spectrometry: Cell Systems www.cell.com/cell-systems.... How great would it be to sequence proteins without a gene-template! We might be approaching this soon.

Very excited to announce that we are hiring for three faculty positions at @universityofleeds.bsky.social in @bioscienceleeds.bsky.social: A/Prof Plant Science, A/Prof Animal Biology and Lecturer in Ecology, Zoology, Biodiversity or Ecosystem Management. Please do get in touch to chat. Links below:
In a new Science study, researchers report on transcriptional adaptation, a dual feedback and feedforward mechanism that uses genetic redundancy to compensate for mutations in protein-coding genes.

Many living people carry fragments of Neanderthal DNA, remnants of ancient interbreeding events, with uneven distribution across chromosomes. New work by @sarahtishkoff.bsky.social lab suggests patterns are most consistent with Neanderthal contribution to human populations being highly male biased.🧪

Pangenome analysis reveals families of ubiquitin-ligase adaptors as key genomic divergence drivers that lead to hybrid incompatibility

Long before Darwin, the French polymath comte de Buffon “accepted both that species could become extinct and that they could change, and he even entertained the idea that humans and apes…might have had a common ancestry.” —Ian Tattersall

🧵Good news out of #NIH today.
(1) NIH is extending #ESI and #K99/R00 eligibility to accommodate researchers whose eligibility would have ended during the previous shutdown. Take a look at NOT-OD-26-020. If your ESI status would have ended in 2025, you get an automatic extension through 2026/03/31.
How does the piRNA pathway solve the self vs. non-self problem? 🧬
Since piRNAs come from single-stranded RNA, how does the cell choose the right ones? For years, "piRNA clusters" were seen as THE privileged source. But are they really special and earmarked for biogenesis? (1/19)
We have an opening for a Research Associate in my group. This is an excellent position for recent graduates or students with a master's seeking research experience prior to graduate/medical school. Apply via the job portal (Job ID: 14797). DM for queries. www.utsa.edu/people-excel...
De novo genes arise from previously non-coding sequences. This evolutionary path — when randomly expressed sequences become folded and active proteins — challenges our understanding of genetic innovation. New Review by @bornberglab.bsky.social and @lacholt.bsky.social out now!
