Sex cells made from scratch could revolutionize human reproduction, but researchers are struggling to translate promising results in mice into benefits for humans, according to a feature in Nature. 🧪

“report the first 3D-printed artificial mini-placentas. These “placental organoids” are an advance over earlier efforts, and will give scientists new ways to study pregnancy and shed light on complications like preeclampsia.”

3D printed mini-placentas offer a new way to study pregnancy complications
‘Placental organoids’ may help research into the early stages of pregnancy and life-threatening conditions like preeclampsia.

piRNAs are essential for transposon silencing in the animal germline.
But how do hosts trap transposon sequences in genomic loci that help establish a piRNA response?

Looking at a natural transposon invasion, Baptiste Rafanel and Kirsten Senti made some remarkable observations.
Antisense transposon insertions into host genes trigger piRNA mediated immunity https://www.biorxiv.org/content/10.1101/2025.07.28.667215v1

Czech readers, this one is for you!
A good read and an important research:
Ve Velké Británii byla zveřejněna první studie o tom, jak se vede dětem počatým specifickou metodou umělého oplodnění, při níž se vedle spermie a vajíčka rodičů používá také mitochondriální DNA další ženy. Smyslem je eliminovat některé dědičné choroby.
Děti se třemi rodiči? Ne tak docela, ale bez problémů to stejně není
Dárcovství mitochondrií je samo o sobě cenný způsob, jak zabránit přenosu vzácných, ale smrtelných dědičných chorob. Práce v utajení a bez zveřejnění výsledků však škodí vědě i narozeným dětem.

I love a good animal communication article.

New research by @kaylakolff.bsky.social & Simone Pika highlighted in @us.theconversation.com suggests turn-taking, a core feature of human language, also plays a role in how chimpanzees communicate.

TLDR 👇
Whose turn is it? The question is at the heart of language and chimpanzees ask it too
Chimpanzees’ turn-taking shows skills that may have supported the evolution of human conversation.

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬
But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯
Our new study reveals how retrotransposons invade the germline directly from somatic cells.

In the ‘90s, Pelisson et al. found that gypsy retrotransposons in flies can go viral—literally—thanks to an envelope gene. Now, @mayavoichek.bsky.social uncovers a wild new path to retrotransposon infectivity. A fascinating story—see Maya's thread
