Interesting #neurobiology paper.

Neurons are very large, with mm to m often separating synapses from nucleus. So how do terminals rapidly make new protein, when these are encoded far away?

Local translation of mRNAs is one way, but that raises the question how mRNAs get to terminals. It is thought that localising RNAs contain 'zipcode' sequences, but not many of these have been found.

This paper now implicates mRNA stability as an important factor for localisation.

What do neurons add to an organism?

"The extraordinary ability to survive the removal and replacement of its entire nervous system makes Hydra uniquely suited to address the question of what neurons add to an extant organism"

We published a new preprint on nitric oxide (NO) signalling in #Platynereis. In the paper Kei Jokura et al. described how NO is required for UV-avoidance behaviour by mediating retrograde signalling to brain ciliary photoreceptors.

Effect of monochromatic light on the behavior of the ctenophore Mnemiopsis leidyi.

4 maneuvering patterns identified:

1 - turn and shift
2 - move sideways
3 - move up along the beam followed by a turn
4 - drop down, stop, lift up and turn

In our new preprint we characterise neuropeptide signalling in the cnidarian .

Daniel Thiel and Luis Yanez-Guerra screened 64 neuropeptides against 161 G-protein coupled receptors () and found activating peptide ligands for 31 receptors.

A project that started with Davi Bock and Wei Lee developing the TEMCA for the mouse visual cortex in Clay Reid’s lab (Bock et al. 2011 nature.com/articles/nature0980), then Bock moving to #HHMIJanelia and developing the instrument much further to deliver the #FAFB volume (Zheng et al. 2018 sciencedirect.com/science/arti ), and then the Seung, Murthy and Jefferis labs automatically re-registering, segmenting and annotating the whole volume via #FlyWire and more.

Extraordinary!

Map of night trains in Europe. In combination with high-speed trains and regional trains, a lot of destinations are one evening plus overnight away. Now if only oil subsidies would end, flight tickets wouldn’t be competitive, particularly with Interrail ticket schemes.

“Rosalind Franklin has been reduced to the “wronged heroine” of the double helix” Instead, “She deserves to be remembered not as the victim of the double helix, but as an equal contributor to the solution of the structure.”

Cover article in Science Magazine shows that comb jellies' epithelial nerve net is slime-mold-like syncytium. No discrete neurons!

Was the nuclear-to-cytoplasmic ratio a key factor in the origin of animal multicellularity?

@eLife

For anyone on the fence about #eLife's new publishing model, note there is no such thing as an "eLife paper", since the purpose of the review process in scientific publishing is to provide accurate, constructive reviews to authors. In modern times, dissemination doesn't depend on mailed-in printed periodicals.

Each eLife publication has an evaluation attached to it in the form of an assessment–be it negative or positive. Critically, authors decide whether to go forward with assessments as they are and go public, or to revise the manuscript and request re-review to improve both manuscript and, consequently, the reviews and assessment.

In other words, nothing changed, except, its authors who decide how to move forward with their own manuscript, rather than editors.
