@St93psg@samquelplaisir En soit il propose juste de pas renouveler les centrale nucléaire jusqymue 2060 pour limiter les dechet nucléaire. Avec comme projet optimiste une possible fusion nucléaire d’ici la. C’est pas déconnant quanf on voit les avancées scientifique.
@ryuk_packm Frere elle est en armure plus casque, c’est une balaillette. Elle a une matraque, une lacrymo, des gants renforcé nan faut arreter de les defendres ces storm troopers la.
@CerfiaFR On change la loi à sa sauce ? Depuis quand le pouvoir etatique donne son avis sur le pouvoir judiciaire ? Et les assurances ? Degradation est un délit punis par la lois, un juge decidera de la peine quand au dommage, laisser les sangsue (assurance) payer pour une fois.
For most of human history, women have had about 100 periods in their lifetimes. Today's women have over 400. A Chinese biologist named Hongmei Wang thinks that gap is part of why women run out of eggs decades earlier than they have to.
Wang is 52. She runs a lab at the Institute of Zoology in Beijing that studies the cellular machinery of fertility. Her idea is simple. Bleed four times a year instead of twelve, save eggs, extend the fertile window. Mouse data so far backs her up.
Before birth control, women were pregnant or breastfeeding through most of their fertile years, and both pause periods. About 100 cycles in a lifetime. Now, with later marriages, fewer kids, and longer lives, the number sits above 400. Each cycle uses up eggs. Run out, menopause starts.
That cycle hypothesis is one of three threads in her lab. The second was a 2024 paper in the journal Cell Discovery. Her team grew lab stem cells, named them M-cells, and injected them into the ovaries of old monkeys past their fertile years. Damage in the tissue healed. Hormones came back. One treated monkey gave birth to a healthy baby. They tried it on 63 women whose ovaries had quit decades early, a condition called premature ovarian failure. Four had healthy children. The team patented the technique and licensed it to a private firm.
The third project is in Barcelona. Wang is partnering with biologist Alfonso Martínez Arias to grow fake human embryos from stem cells. Almost every country bans growing real ones in a lab past 14 days. The window from day 14 to day 28 is when the body's basic blueprint forms, the layers that turn into brain and heart and bone. Almost everything we know about it comes from animals, because the human version has been off-limits in labs for decades. The fake embryos are how Wang plans to look inside.
She does not oversell any of it. "When we stop ovulation, we save more eggs, but we also stop the body from making estrogen, and that molecule is absolutely vital for health," she told El País. Years of low estrogen weaken bones and wear down the heart. She is still working out how to keep the eggs without paying that price.
The backdrop is China. Last year, the country had 7.92 million babies, a 17% drop and the lowest birth rate since 1949. The population shrank by 3.4 million people in a single year. Wang knows her work will not arrive in time to fix those numbers. But the girls born this decade may grow up with a reproductive clock no woman has ever had before.
7/7 L’OMS classe d’ailleur la pilule comme cancérigène de Groupe 1 (comme l'amiante). Le risque de cancer du sein bondit de 20 % : c'est 1 cancer sur 5 lié à sa prise. Aussi en France, 20 jeunes femmes saines meurent chaque année d'embolie.
1/7 Il y a 50 ans, avoir 4 ou 5 enfants était la norme. Aujourd'hui, c'est souvent perçu comme une irresponsabilité sociale ou écologique. Ce basculement n'est pas "naturel" : il a été piloté par un Soft Power massif soutenu par des puissances financières. 👇
6/7 Hollywood a fait le reste. Des magnats comme Lew Wasserman ont imposé le modèle de la femme "libérée" des contraintes biologiques. La pilule est devenue un accessoire glamour, masquant ses dangers réels derrière un vernis de modernité.
