This will be an amazing tutorial on Comparative Genomics, covering the foundations, key challenges, and practical tips from the Orthology Clinic! It’s part of ECCB, but you can also join the tutorial only on September 3rd! #GenevaLovesData

Orthology is central to comparative genomics. Join us at the tail end of eccb2026.org in Geneva (3 Sep) for a full day of orthology: bit.ly/ECCB_ortho Intro to major tools, hands-on tutorials, and an "orthology clinic" for your own data. Extend your ECCB trip, or come just for the tutorial.

my section was all about uterine tissues creating happy little "benign" tumors that make your life hell but since they are not cancerous it takes forever to diagnose and find a treatment that works for YOU! #SciArt #endometriosis #fibroids #adenomyosis

cartoony page from the zine I drew, the colors are dark blue, light blue, yellow, orange, light pink and dark pink. the text is When the uterus tissues go WILD! - FIBROIDS- non-cancerous abnormal growths of muscle tissue extremely common, 2/3, ~50% asymptomatic unclear origin, estrogen? progesterone? at higher risk: African Caribbean, family history, early periods, obesity heavy bleeds, anemia, back pain infertility constipation, frequent urination Dr. Platypus fact: one of the biggest fibroid was 28kg in a 53 year old Singaporean patient! the middle drawing is of an uterus absolutely covered in pink blobs representing the different type of fibroids: pedunculate (outside), pedunculate (inside), subserosal, submucosal, utnramuralcartoony page from the zine I drew, the colors are dark blue, light blue, yellow, orange, light pink and dark pink. the text is When the uterus tissues go WILD! - ENDOMETRIOSIS- endometrial-like tissue growing outside of the uterus unclear origin (cells escaping fallopian tube at menstruation, immune dysfunction, local estrogen production, circulation, surgery, genetics) Dr. Platypus fact: endometriotic lesions were even found in the brain, which caused neurological and psychiatric symptoms! ~8 years to get diagnosed 1/10 people bleeding outside and inside infertility pelvic PAIN! during intercourse, bowel movement, urination, or for no good reason nausea the middle drawing is of an uterus, guts, kidneys ovaries and bladder covered in pink endometriotic lesions, none of the organs are happy about it, one ovary has a massive pink chocolate cyst on it (a cyst full of endometrial tissue and blood)cartoony page from the zine I drew, the colors are dark blue, light blue, yellow, orange, light pink and dark pink. the text is When the uterus tissues go WILD! - ADENOMYOSIS- endometrial tissue frowing inside the muscles of the uterus 1/10 people, and they might not even have symptoms (one figure sayinh you telling me WHAT??) unclear origin... shocking i know... estrogen?? other hormones? most likely in: +30 years, abdominal surgery, given birth heavy abnormal bleeding, anemia, pain bloating, fullness infertility Dr. Platypus fact:you can have endometriosis, adenomyosis, and firboids ALL AT ONCE!... and they all have similar symptoms the middle drawing is of an uterus absolutely covered in pink blobs representing the endometrial tissue growing within the muscle: focal (adenomyoma), diffuse, enlarged uteruscartoony page from the zine I drew, the colors are dark blue, light blue, yellow, orange, light pink and dark pink. the text is When the uterus tissues go WILD! - MANAGING- there is no one-size-fits-all treatment, care ranges from less to more invasive first you need to diagnose the problem: ultrasound, blood markers, Magnetic Resonanse Imaging (MRI), surgery etc. PAIN CONTROL: painkillers and anti-inflammatory drugs, physiotherapy, heating pads or hot water bottles, transcutaneous electrical nerve stimulation (TENS) HORMONAL MEDICATION: IUS, mini pill, implants (progestogen only), combined pill, patches (progestogen + estrogen), hypothalamus pills injections (GnRH agonists and antagonists) SURGERY (diagnostic, to alleviate symptoms, and curative) laparoscopy, transvaginal hysteroscopy, abdominal (all biopsied) diseased tissue removal by laser or surgical hysterectomy: curative for adenomyosis and fibroids, but harder to access if <45 Dr. Platypus fact: platypuses don't have a uterus*(long oviduct, sometimes called the "uterus") so don't need to worry about any of this

the culmination of one year of collaborative work on a #SciArt zine discussing gynecological issues, finally in print form! from a lovely team from the @sangerinstitute.bsky.social with special thanks to Dr @talkswithdrsesay.bsky.social and Dr Gioia Canciani for reviewing the contents! 🥼🩸

I'm a fan of the new(ish) Comparative Genome Viewer feature on NCBI: www.ncbi.nlm.nih.gov/cgv which provides interactive whole-genome riparian plots, like this for Helicoverpa sp, which allows you to quickly and easily examine interesting features. Only a handful of genomes on there for now though!

a whole genome riparian plot from the NCBI Comparative Genome Viewer. Two parallel rows; top labelled for Helicoverpa zea, bottom for Helicoverpa armigera. Each row is divided into 31 Chromosomes. Each chromosome is connected by a lines, which correspond to homologous regions. The connecting lines are green to indicate same-orientation homology, and blue to indicate reverse-orientation homology. A zoomed-in view of a small region of Chromosome 24 from the previous figure, with one inversion labelled centrally. Gene tracks are present on both chromosomes.

Very excited to share our new manuscript by Arif Maulana @arf-mln.bsky.social on 338 beetle genomes. It shows how beetle genomes have evolved and how this compares to fly and Lepidoptera genome evolution. It was a great pleasure to collaborate with @kamilsjaron.bsky.social and his team on this.

New preprint: 338 coleopteran genomes reveal exceptional rearrangement variation compared to other insect orders. Big congrats to @arf-mln.bsky.social, for getting this giant piece together. Big collaboration of @joanameier.bsky.social's and my groups. 🧵👇 doi.org/10.64898/202...

Phylogeny of 338 species with tips painted by the chromosomal ancestry of their contemporary genomes (well separated colours indicate only few changes, while blending indicates rearrangements). Colouring of the branches is by the number of rearrangements. The ring between paints and phylogeny indicates wether the chromosomal rearrangement was fusion dominated (brown) or fission dominated (teal) process.

🚨 Why can’t mammals regenerate limbs like frog tadpoles or salamanders? In our new paper in @science.org , we show that species-specific oxygen sensing acts as a gatekeeper for initiating limb regeneration 🐭🐸 🔗 www.science.org/doi/10.1126/... #EvoDevo

Species-specific oxygen sensing governs the initiation of vertebrate limb regeneration

Why mammals cannot regenerate limbs like amphibians do presents a long-standing puzzle in biology. To uncover the underlying differences, we compared amputation responses of embryonic mouse (Mus musculus) and Xenopus laevis tadpole limbs. Lowering ...

On my way back after 2 inspiring and thoughtprovoking days in Edinburgh where we hosted a @royalsociety.org meeting on Pangenomics. Many thanks to co-organisers @charlottewright.bsky.social, @henrylnorth.bsky.social, to Ash Carver for handling the logistics, the excellent speakers and all attendees.

Charlotte Wright@charlottewright.bsky.social · 2mo ago

An excellent two day @royalsociety.org meeting packed with discussion about how pangenomics is revolutionising evolutionary biology. Thank you to all the amazing speakers and attendees who contributed to the rich discussions and @henrylnorth.bsky.social & @joanameier.bsky.social for co-organising!

Jialin Wei: very nice results on convergence of genome evolution with terrestrialisation in animal evolution #EED2026 https://doi.org/10.1038/s41586-025-09722-4

Convergent genome evolution shaped the emergence of terrestrial animals - Nature

Comparisons of 154 genomes from 21 animal phyla and outgroups have been used to reconstruct ancestral adaptation to life on land across 11 distinct terrestrialization events, revealing strong evidence for convergent genomic evolution across the animal kingdom and recurring periods of terrestrial colonization.
