近期,科学家在一项开创性研究中,成功利用人类皮肤细胞创造出可受精的卵子。尽管这些卵子在染色体上存在异常,目前无法用于生育,但这项技术为未来治疗不孕症提供了重要的概念验证。研究人员通过替换卵子细胞核和诱导其染色体减半,并成功使其受精并发育成早期胚胎。尽管这一进展意义重大,但科学家们也指出,该技术距离应用于人类临床试验可能还需要十年的进一步研究。

🔬 **技术突破**: 科学家成功利用人类皮肤细胞,通过替换卵子细胞核并诱导染色体减半,创造出能够被受精的卵子。这标志着在再生医学领域的一项重要进展。

💡 **潜在应用**: 尽管目前创造的卵子存在染色体异常,无法直接用于生育,但这项技术为未来治疗由卵子缺陷引起的不孕症提供了重要的概念验证,有望为有生育需求的人群带来希望。

⏳ **未来展望**: 科学家们普遍认为,这项技术距离安全有效地应用于人类临床试验还需要相当长的时间,预计可能需要十年或更长时间的深入研究和优化,以克服现有的技术挑战和伦理考量。

[6.5] Scientists create fertilizable eggs from human skin cells — apnews.com (+32)

Scientists created fertilizable eggs from human skin cells, but chromosomal abnormalities make them unusable. The work is a proof-of-concept that could one day help treat infertility.

Researchers in Oregon replaced an egg's nucleus with one from a skin cell and induced it to halve its chromosomes. After fertilization, some developed into early-stage embryos but were genetically abnormal.

While considered an important step, scientists caution it may take a decade of additional research before the technique could be ready for human trials to help people conceive.

[6.2] NATO allies can now shoot down Russian warplanes crossing alliance borders — lemonde.fr (French) [$] (+229)

NATO has changed its rules to allow the downing of Russian aircraft violating its airspace, marking a major shift in its military posture since the start of the Ukraine war.

The decision by all 32 members follows recent Russian incursions, including drones on September 9-10 and fighter jets entering Estonian airspace on September 19.

This change to NATO's classified "rules of engagement" signals a strategic move beyond its previous policy of only providing Ukraine with weapons and intelligence support from behind the front lines.

[6.3] OpenAI integrates instant purchases into ChatGPT — fortune.com (+26)

OpenAI launched "Instant Checkout", allowing U.S. users to buy products directly within ChatGPT. The move into e-commerce is a direct challenge to Google's search advertising model.

Powered by a new Stripe protocol, the feature launched with Etsy sellers and will soon add over a million Shopify merchants. OpenAI will collect a small fee from the merchant on each transaction, helping to monetize its large user base.

The system replaces a previous feature that only linked out to websites. OpenAI says product results are organic and unsponsored, ranked on relevance, availability, and price, not on merchant fees.
