As @the_node celebrates their 15 year anniversary this year, we want to collect feedback from you, our community, to ensure the Node is still relevant and useful.
If you’ve ever visited the Node to read, write or interact with the developmental and stem cell biology community, please spare five minutes to take their survey:
I’m currently looking for a post-doc in the UK, particularly to work on projects that employ in-vitro reconstitution and quantitative #microscopy approaches to study #cellbiology processes (esspecially #membranetraffic) + would be grateful for sign-posting towards openings!

Where do #proteins go in cells? Next-generation methods map the molecules’ hidden lives! Spatial #proteomics at the lab of Matthias Mann at Max Planck Institute for Biochemistry is helping biologists to uncover how cells work by mapping where proteins operate. 
Very interesting preprint from Jurgen Klingauf and colleagues demonstrating that synaptic vesicle retrieval is clathrin-mediated.
The debate over the mechanism has been going since the 1970s. In recent years, ultra-fast endocytosis has become accepted. In this paper it's argued that if you look at retrieval of cargo, rather than membrane, then it is mainly driven by clathrin.
Interested in membrane organization and contact sites?
Join the DGZ Focus Workshop tomorrow on March 25, 12:00 – 13:45!
The workshop was organized by our research group leader Katja Zieske, among others, as part of the German Society for Cell Biology.
Neighborhood dispute among cells: Whoever successfully transmits force wins
Cells constantly compete, eliminating weaker ones to maintain tissue health. Researchers from #MPZPM, #InstitutJacquesMonod and #NielsBohrInstitute discovered a new strategy in mechanical cell competition: the ability to transmit force determines the winner. Their findings challenge classical views on #CellCompetition.

"There's no explanation other than that these cells are breathing oxygen at the same time that they are breathing elemental sulfur," said first study author and Montana State University graduate student Lisa Keller.
"This is really interesting, and it creates so many more questions," Keller added. "We don't know how widespread this is, but it opens the door for a lot of exploring."

"Knowing how more than one kind of phage can survive over time on a single bacterium could help in designing next-generation phage cocktails," said Nora Pyenson, PhD. "For example, each phage species might attack the bacterium in a different part of its lifecycle, enabling the whole population to be killed before resistance to the treatment evolves."

"The structure that allows the chloroplast to make necessary changes was found to be a network of thin filaments. Together, these filaments form a material that can easily contract and expand in all directions."
"This large-scale, community-driven, globally representative and rigorously curated atlas will evolve continuously and remain accessible to all to advance our understanding of the human body in health and treatments for disease," noted Dr. Aviv Regev, founding co-Chair of the HCA, now of Genentech.

Microbes have been competing for space and resources in a kind of microbial arms race for many years, and some cells have ways to attack and kill other cells.

As I get ready for this year's Maker Faire, I can't help but be nostalgic for the first years of that amazing event, and what we did in those years. I really need to work more on documenting it. Some of the best things I've ever done took place at the Maker Faire :D
