🪱 Selfish genes are everywhere and drive some of biology’s biggest innovations (CRISPR, antibody recombination, epigenetics). Yet almost no one asks the obvious question: how does a selfish gene begin? Our new manuscript uncovers how selfishness can emerge directly from the host genome.

Our new pre-print is up:
“Capillarity Reveals the Role of Capsid Geometry in HIV Nuclear Translocation.”
👉 arxiv.org/abs/2510.26357
It explores how the shape of the HIV capsid helps it pass one of biology’s tightest gates — the nuclear pore.

Capillarity Reveals the Role of Capsid Geometry in HIV Nuclear Translocation
The protective capsid encasing the genetic material of Human Immunodeficiency Virus (HIV) has been shown to traverse the nuclear pore complex (NPC) intact, despite exceeding the passive diffusion thre...

Did you know? Bar-tailed Godwits (Limosa lapponica) fly >10,000 km nonstop from Alaska to New Zealand - the longest flight of any bird. Before takeoff, they double their weight and shrink their gut. pubmed.ncbi.nlm.nih.gov/18974033/ 📸 USFWSAlaska, via Wikimedia Commons (CC0)

Was wissen wir über HIV in 🇩🇪? #WeltAIDSTag

Schätzungen des RKI für 2024 zeigen, dass sich 2.300 Menschen mit #HIV infiziert haben. Das sind ~200 Neuinfektionen mehr als 2023.

Alle Zahlen, Details zu Erstdiagnosen und welche Rolle Prävention spielt, lest ihr im #EpidBull

Das Nationale Referenzzentrum für Poliomyelitis und Enteroviren hat in einer Abwasserprobe aus Hamburg Polio-Wildviren vom Typ 1 nachgewiesen.

Mehr zur aktuellen Situation und den Empfehlungen für medizinisches und labortechnisches Personal im aktuellen EpidBull:
🔗 www.rki.de/DE/Aktuelles...
Beschreibung: Hellblauer Hintergrund. Oben Überschrift „Aktuelle Situation“. Darunter vier Absätze mit Icons links. Unten ein Kasten mit Glühbirnen-Symbol und Hinweistext. Ganz unten steht „Robert Koch-Institut“. Text auf der Kachel: „Aktuelle Situation“ „Das Nationale Referenzzentrum für Poliomyelitis und Enteroviren (NRZ PE) hat in einer Abwasserprobe aus Hamburg Polio-Wildviren vom Typ 1 (WPV1) nachgewiesen.“ „Die Genomsequenz zeigt eine sehr starke Ähnlichkeit mit einem genetischen Cluster in Afghanistan, wie Analysen in Zusammenarbeit mit der Weltgesundheitsorganisation (WHO) ergeben haben.“ „Die Abwasserprobe wurde in Hamburg am 6.10.2025 entnommen und im Rahmen des Forschungsprojektes zum Nachweis von Polioviren im Abwasser (PIA) analysiert.“ „Die zuständige Landesstelle in Hamburg wurde informiert.“ Kasten: „Dem RKI wurden bislang keine klinischen Fälle oder Verdachtsfälle von Poliomyelitis (Kinderlähmung) übermittelt.“ Beschreibung: Hellblauer Hintergrund. Überschrift „Was bedeutet der Virusnachweis?“. Oben ein gestrichelter Kasten mit Glühbirnen-Symbol, darunter längere Absätze zu globalem Vorkommen und genetischen Eigenschaften. Unten steht „Robert Koch-Institut“. Text auf der Kachel: „Was bedeutet der Virusnachweis?“ Kasten: „Der Nachweis von Polio-Wildviren im Abwasser ist ein ungewöhnliches, aber grundsätzlich nicht unerwartetes Ereignis.“ „Polio-Wildviren zirkulieren aktuell nur noch in Afghanistan und Pakistan. In den vergangenen Jahren wurden WPV1 aber auch außerhalb dieser zwei Länder nachgewiesen: in Umweltproben im Iran (2019) und bei bestätigten Fällen in Malawi (2021) und Mosambik (2022).“ „Der aktuelle Nachweis spricht dafür, dass die Viren von mindestens einer Person ausgeschieden wurden, die sich um den Zeitpunkt der Abwasserprobenahme in Hamburg aufgehalten hat.“ „Eine Verbindung zu den zirkulierenden Impfstoff-abgeleiteten Polioviren Typ 2 (cVDPV2), die seit Ende 2024 in Abwasserproben in Deutschland und mehreren anderen europäischen Ländern nachgewiesen wurden, besteht nicht, da es sich um einen anderen Typ von Polioviren handelt.“ Beschreibung: Hellblauer Hintergrund. Überschrift „Was bedeutet der Virusnachweis?“. Mehrere Absätze zu Erkrankungsrisiken und Impfung. Unten ein großer gestrichelter Kasten mit Glühbirnen-Symbol und Erläuterung des Risikos. Ganz unten steht „Robert Koch-Institut“. Text auf der Kachel: „Was bedeutet der Virusnachweis?“ „Beide Typen von Polioviren (cVDPV2 und WPV1) können bei ungeimpften oder nicht vollständig geimpften Menschen die Erkrankung Poliomyelitis auslösen.“ „Eine vollständige Poliomyelitis-Impfung mit dem in Deutschland eingesetzten Totimpfstoff schützt zuverlässig vor der Erkrankung, jedoch nur eingeschränkt vor einer Ansteckung und Weitergabe der Erreger. Infizierte Menschen können potenziell auch andere Menschen anstecken.“ „Die Poliomyelitis-Impfquoten bei Kindern liegen in Hamburg über dem bundesweiten Durchschnitt.“ Kasten: „Das Risiko für die Bevölkerung in Deutschland durch Polio-Wildviren wird aufgrund der hohen Impfquoten und des einzelnen Nachweises im Abwasser als sehr gering eingeschätzt, auch wenn das Auftreten eines klinischen Falles bei ungeimpften Personen möglich ist.“

#MicrobiologyMonday: Can bird song shape your microbiome? 🐦Scientists propose that interactions with nature may influence gut microbiome composition, suggesting it is shaped not just by direct microbial exposure, but by multisensory experiences. #mSystem asm.social/2Cx
Beyond direct microbial colonization: multisensory experiences in nature and their potential to indirectly influence the gut microbiome via multiple biological systems and axes. For example, stress can impair gut immunity in part by downregulating NLRP6 activity, a key regulator of the inflammasome and microbial balance (42); elevated cortisol increases gut permeability (43), and nature walks (and listening to nature sounds) reduce cortisol (44) and increase parasympathetic tone (45, 46). Exposure to natural biodiverse materials can reduce pro-inflammatory cytokines (27, 28). All of these processes can influence the gut environment, composition, and dynamics.
