Social unicellular amoebae create actin-rich tunneling nanotubes that physically connect cells, allowing them to share cytoplasm and organelles, and helping the cells communicate—a possible step on the road to multicellularity. In PNAS Nexus: ow.ly/jyv350ZvQC5

Apparently, amoebae have networking skills too! Excited to share our latest publication on tunneling nanotubes (TNTs) in lower eukaryotes such as amoebae 🥳 🔗 Article: academic.oup.com/pnasnexus/ar... @pnasnexus.org @pnas.org @pstallforth.bsky.social @eswarappalab.bsky.social

In the tun state, tardigrades slowed the flow of heat through their bodies. Active animals did not survive one hour at 45°C, while some dehydrated ones endured far higher temperatures. doi.org/hb53bx

Tardigrades reveal extreme heat-blocking survival trick while in tun state
Tardigrades, also known as water bears or moss piglets, are tiny eight-legged animals that can survive in extreme environments, where humans and most other animals would die.

Publication alert 📢 Tardigrades really said: “85°C in tun state? Easy peasy lemon squeezy 😎🔥” How do these tiny water bears survive extreme thermal stress? 🤔 Link: shorturl.at/8V3S5 #tardigrade #biology #extremotolerance @royalsocietypublishing.org
