Le #CIO impose des #tests_genetiques à toutes les concurrentes aux #jeux_olympiques.

Le but : écarter les personnes porteuses du #geneSRY (gène de la masculinité pour faire (très !) simple) des compétitions.

Cette mesure soulève de nombreuses questions en lien avec l' #egalite , dont :

1) comment intégrer les personnes #trans et #Intersexe dans les compétitions (éviter la discrimination) - sans qu'elles puissent être accusées d'avoir un avantage injuste ?

2) Aucun sportif n'a le même #ADN. Certains traits génétiques sont avantageux pour certains #sports. Faut-il interdire de compétitions tous les sportifs favorisés par leurs #genes?

Etc...

#Regeneration of fins and limbs relies on shared cellular playbook
Immune cells, blood and repair #genes act in concert across three regenerating #vertebrates
Team cut fins off #bichirs and tracked #gene activity at wound after one, three and seven days, which revealed types of cells present and activity. Team compared data to similar new and existing data about #axolotl, salamander that regrows limbs, and #zebrafish, a that can regrow tips of fins

Regeneration of fins and limbs relies on a shared cellular playbook

The findings strengthen the case that regeneration is an old trait, offering insights into how complex tissues rebuild themselves.

🧬🔬 We often think of #cloning as making a perfect carbon copy, but new #research shows it's much more complicated.

Scientists found that cloned #animals experience rapid changes in how their #genes are expressed, leading to #health issues that aren't present in naturally born animals.

Landmark experiment reveals a big unexpected problem with cloning

A 20-year study has shown that, like photocopying photocopies, cloning doesn't produce perfect copies – with big implications for farming, conservation and de-extinction

Did All Of Britain’s Moths Use The Same Gene to Become Dark?

"More than 100 species of moths became darker to blend in with pollution during Britain’s industrial revolution, but did these different moth species all rely on the same gene to adapt?"
