Neue Experimente in den USA und Großbritannien zeigen Fortschritte in der Embryonenforschung mittels Basen-Editierung. Forscher betonen den Wert für die Grundlagenforschung, warnen aber vor voreiliger klinischer Anwendung und fordern breiten gesellschaftlichen Diskurs.
Pesquisa publicada na "The Lancet" analisou dez "add-ons" de reprodução assistida e concluiu que apenas três mostraram algum benefício limitado. Para os demais, não houve efeito ou a qualidade dos dados foi baixa, gerando incerteza.

Forscher um Dieter Egli haben menschliche Embryonen mittels Base-Editing manipuliert. Die Methode ist schonender als Crispr-Cas9. Kritiker sehen darin eine Gefahr der Eugenik, während andere die Forschung als wichtigen, aber noch unbedenklichen Fortschritt betrachten.
French women undergoing IVF are frustrated by the ban on preimplantation genetic testing (PGT-A), which could identify chromosomally abnormal embryos. Patients like Aurélie, who has had multiple failed transfers and miscarriages, advocate for its legalization, while experts debate its scientific evidence and potential for eugenics.
A meteorite found in the Sahara, NWA 12774, suggests the early solar system may have contained a lost planetary embryo. Analysis of clinopyroxene crystals indicates formation under extreme pressure, implying a parent body much larger than a typical asteroid, possibly approaching lunar size.
A research team led by Tsai Shao-cheng has discovered that the length of primary cilia in the uterine lining is crucial for successful embryo implantation. The study, supported by the National Science and Technology Council, found that these cilia shorten with age and in women with endometriosis. Using a drug to inhibit TGF-β1 signaling restored cilia length in mice, increasing pregnancy rates by 40%.
China's Tianzhou-10 mission carried human artificial embryos to the Tiangong space station to study early human development in microgravity, addressing critical questions about reproduction in space.
