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

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.

❄️🧬 Can we generate high-quality reference genomes without the cold chain? A new study suggests the answer is yes. DNA preserved at room temperature for up to one week produced chromosome-scale reference genomes. 📖 tinyurl.com/3zwtj9ka #Genomes @gigascience.bsky.social @sangerinstitute.bsky.social
Close-up photograph of a mosquito perched on a green blade of grass against a dark background. White text at the top reads, "Breaking the Cold Chain." Additional text states, "Room-temperature preservation enables chromosome-scale reference genomes." "GigaScience 2026" appears in the lower-right corner.Three researchers collect biological samples in a forest. One researcher kneels while holding a collection tube beside an insulated cooler, and two others stand nearby preparing samples. A large arrow points to the cooler. Text explains that high-quality reference genomes traditionally require specimens to remain frozen from collection through DNA extraction, highlighting the challenge of maintaining the cold chain during fieldwork.

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.
