Physalia physalis (bluebottle/Portuguese man o' war) split into four species

Physalia is an iconic marine genus distributed across the world's oceans, regularly washing up on beaches around the globe and often inflicting painful stings for ocean swimmers. The genus has had quite a complex taxonomic history, and the number of accepted species has changed numerous times over the last few centuries. This culminated in a comprehensive [2019 review by Pugh](https://drive.google.com/file/d/1gnVhfDa4Sp_NiGOQs77FSWOUg-PGVnvY/view?usp=sharing), who recognised a single species, Physalia physalis, and that >to establish several more species [researchers] would need to establish definite morphological differences from P. physalis That evidence has now arrived. Last week, [a new paper titled 'Population genomics of a sailing siphonophore reveals genetic structure in the open ocean' was published in Current Biology](https://drive.google.com/file/d/1Ilzsm0A1yH-lJ00UfcOV0tKS2PQcwhvb/view?usp=sharing), led by Samuel Church and with a very impressive author list.

This is why I cancelled my Microsoft subscription. (Publishers love Word .docx files; they also love contracts that require the author to warrant that the manuscript is 100% their own work. If I use Word today my compliance with my book contracts could be open to question.)

#Gletscher in der #Schweiz, den #USA und #Kanada haben zwischen 2021 und 2024 rund 12 % ihrer #Eismasse verloren.

Ursachen sind #Hitze, #Trockenheit und dunkle Partikel wie #Waldbrandasche und #Saharastaub.

Besonders stark war der #Eisverlust im Rekordjahr 2023. Das tatsächliche Abschmelzen könnte schneller verlaufen als aktuelle Modelle vorhersagen.

Gone with the glaciers: Researchers track unprecedented ice loss

A study published in Geophysical Research Letters reveals that glaciers in western Canada, the United States, and Switzerland lost around 12% of their ice between 2001 and 2024.

Reputation ohne Paywall?

Wissenschaftliches Publizieren im digitalen Wandel

https://doi.org/10.26298/1981-5838

Reputation ohne Paywall? | Melusina Press

Der vorliegende Sammelband enthält Beiträge zu den Ergebnissen der Tagung "Reputation ohne Paywall", die von der *AG Digitales Publizieren* des Fachverbandes *Digital Humanities im deutschsprachigen Raum* im Oktober 2024 in Darmstadt, anlässlich ihres 10-jährigen Bestehens, veranstaltet wurde. Die versammelten Beiträge entwickeln neue Perspektiven auf Funktion, Wirkungsweise und Struktur von Reputation als sozio-kulturelles Organisationsmittel im Wissenschaftssystem vor dem Hintergrund von Entwicklungen wie der digitalen Transformation oder *Open Access*. Diskutiert wird zum einen die Selbst-Referenzialität des Reputationssystems, die zu einer Verzerrung der vermeintlich abgebildeten wissenschaftlichen Leistung führt sowie strukturelle Innovationsprozesse erschwert. Zum anderen werden alternative Reputationsmodelle entworfen und Strategien entwickelt, wie *Open Access* Akteure sich erfolgreich im gegenwärtigen Reputationssystem positionieren können.

Let's talk about open science, doing research projects that serve developers, and money

that's right

🙀 MONEY 🙀

Right up top I am going to tell you: this is a "capitalism is bad"-free thread. You know, I know, we all know. Please do not reply with "capitalism is bad"

Check out @SafeguardingResearch , they are doing exactly that! Decentralized backups of rescued data in a torrent swarm. Also including arxiv, if I'm not mistaken.

kind of abstract question, but i'm curious to hear about how anxiety feels to someone who does not have an "inner monologue" style of thinking in words. like when my thoughts race, i hear them in fast sentences, haha. do you experience something different? would you like to share that?
