They said it, not us...😇 Our "fundamental" and "convincing" study on what evolution can teach us about #infertility is finally out. TL;DR? Check out this primer by @elife.bsky.social to get the lowdown on what we discovered by looking at the past of human sperm. elifesciences.org/digests/9577...
How to build a sperm cell
A shared set of old, deeply conserved genes presides over the development of sperm cells in humans, mice and fruit flies.

"Como podem as instituições de ensino superior afirmar que cuidam das pessoas, quando mantêm centenas de docentes num limbo contratual, sem estabilidade, sem progressão e sem reconhecimento formal do seu mérito académico?"

Saúde mental para as redes sociais, precariedade para os docentes
As universidades e politécnicos celebram a saúde mental com discursos, mas esquecem a realidade dos seus docentes, muitos presos a vínculos precários que minam o bem-estar que dizem promover.

John Gurdon, yr beloved @germcells.bsky.social first and foremost scientific reference has passed away. Here's to a person who was told he couldn't make it and decided to make it on his own terms 🥂 Rest in power, John!

Great work from Aurora's lab! 👌
🚨 New from our lab in #ScienceAdvances!

RAD21L cohesin acts as both a 3D genome architect and a transcriptional gatekeeper in the male germline. Its loss disrupts both structure and function—highlighting the tight link between genome folding and gene regulation

Meiotic cohesin RAD21L shapes 3D genome structure and transcription in the male germline
Deletion of the meiotic subunit RAD21L alters 3D chromatin structure and transcription in the mammalian male germ line.

Mais um dia normal na #Fertagus. Homem com duas crianças tem ataque de pânico em carruagem com lotação máxima excedida e ativa abertura de porta de emergência (com comboio prestes a iniciar marcha). Vai ser preciso morrer alguém para este serviço funcionar com um pingo de humanidade?

À atenção do Governo de Portugal.
Science is a long game.

Translational science, or clinical medicine is only possibly because of basic science discoveries where the clinical applications are not yet known.

Also: Nobels are typically awarded for basic science… *exploratory* basic science.

True story.
Over 20 years after Julius’s lab and mine cloned TRPM8, it is rewarding to see this science helping patients. The TRPM8 agonist Tryptyr treats dry eye by increasing tear production. A reminder that NIH-funded curiosity-driven research translates to medicines.
