Meğer 300 milyon sperm yumurta finaline doğru 100 metre yarışı yapmıyormuş ve birinci gelen sperm döllenme hakkını kazanmıyormuş. En iyi, en uygun olan sperm yumurtaya girebiliyormuş. Onu da yumurta seçiyor. Stockholm Üniversitesi ve Manchester Üniversitesi bünyesindeki araştırmacılar yumurtayı çevreleyen ve sperm hücrelerini çeken kimyasal maddeler içeren foliküler sıvının, her kadında farklı bir kimyasal imza taşıdığını keşfetmişler. Bu çalışma, döllenmenin sadece en hızlı yüzen spermin yarışı kazandığı düz bir süreç olmadığını, yumurtanın aktif olarak sürece dahil olduğunu ve kendi tercihini yaptığını ortaya koymuş. Bu seçilim mekanizmasının arkasındaki temel evrimsel mantık da genetik kaliteyi maksimize etmek. Yumurta, kendi kimyasal sinyalleri sayesinde genetik olarak daha uyumlu veya daha yüksek kaliteli (DNA bütünlüğü daha iyi olan) spermleri "koklayarak" kendine çekmeye çalışıyormuş. Buna "kriptik seçilim" deniyor. Yumurta hücresi biyokimyasal düzeyde ikinci bir oylama yapıyor. Bu, kadının seçtiği partnerin genetik profilinin yumurta için her zaman en iyi olmadığı durumları açıklıyormuş. Nedeni açıklanamayan kısırlık vakalarının bir kısmının, yumurta ve sperm arasındaki bu kimyasal uyuşmazlıktan kaynaklanabileceğini düşünüyor bilim insanları.

This is Messier 82 (M82), better known as the Cigar Galaxy. M82 has been observed many times before, including by @Hubble_Space but its details have until now been shrouded by dust. After 65 hours of observations with the #NIRCam# on Webb, which can pierce through this dust, M82 has been revealed in all its sparkling glory. There are approximately 16.5 million stars visible in this image! 🤯 Read more: #WebbSeesFarther# 📷 @NASA , @ESA , @csa_asc , A. Smercina (STScI), T. Williams (University of Manchester), A.

By this time next month, Andy Burnham could be running the country.⁠ ⁠ It is to his Manchester years that Westminster politicos and the corporate world will now turn for clues to his reinvention. It was a period Jennifer Williams followed closely:

Marlon West has done more than any politician to end the Pakistani rape gangs. His daughter is a survivor. He has seen the evil. If elected as Greater Manchester mayor for Restore Britain, he will go to war with the rape gangs. Watch this. @MarlonTag is a proper fighter.

Who is Britain’s next prime minister? Sir Keir Starmer has resigned, and it’s all but certain that the new leader will be Andy Burnham. He’s been in politics since 2001 and has spent the past nine years serving as the mayor of Greater Manchester—a stint that’s made him popular with the Labour Party and the electorate. Find out why Mr Burnham might find Sir Keir a hard act to follow:

Good morning, Asia. While you were sleeping, our most-read story was about the outgoing Greater Manchester mayor gearing up for ‘access talks’ with civil servants as he prepares to enter Number 10 within weeks.

Just in: Wes Streeting has thrown his support behind Andy Burnham in an indication that the former Greater Manchester mayor will be able to succeed Sir Keir Starmer as prime minister without a contest. Follow our live blog for the latest developments:

Andy Burnham's return to parliament has made the former Greater Manchester mayor the frontrunner to succeed Keir Starmer as prime minister, and with him comes 'Manchesterism,' his vision for Britain. Here's what we know about his economic model
