🚨🚨GRAVE: Mangá Yuri "LOVE-BULLET" será publicado no Brasil pela JBC.
Garotas que morrem sem conhecer o amor se tornam cupidos, que usam armas para acertar seus alvos, ao invés do tradicional arco e flecha. Seu objetivo é simples: dar um fim satisfatório à triângulos amorosos
@dudxgc@Tartarugadovale Eu li esse livro sem saber da história, quando eu descobri foi uma surpresa 😂 fui ler esperando um livro de ação e luta, até perceber que tinha um enredo diferente do que eu esperava. ( Fui pela capa antiga)
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.
Eu acho engraçado a semelhança que eu vejo do contexto cristão na caçadora de dragões, basicamente Namsaras são apóstolos, enquanto os dragões são servos de Deus, as histórias contadas é a bíblia e a Iskari nada mais é do que uma versão de Paulo antes e durante a conversão
