Cells Weekly #44

Let’s start off with a quote via Chris Mooney, from climate scientist Andrew Dessler:

Science is much messier and, frankly, less scientific than most people realize. Despite that, science is incredibly successful and, I believe, a force for good in this world, and I am proud to be a scientist.

And so, in the interests of promoting science posts relating (however broadly) to my interests of cell and molecular biology, here’s my biweekly installment of “Cells Weekly,” a showcase of topical blog posts by others from the past week.

From Free-Living Bacterium to Cellular Citizen – See how organelles differ from their prokaryotic forerunners, especially when it comes to fusion and division of mitochondria and chloroplasts. At Small Things Considered.

Do the Bacteria Dance! – Dance, dance, ooh look, bacteria! Everywhere you look, bacteria. Over at Deep Sea News.

Sex, Flies, and Lateral Gene Transfer – Bacteria-host cell interactions reveal surprising examples of gene transfer, at A Snail’s Eye View.

Worms, Brains & Chips – Bringing some innovation to neuroscience, some scientists are using microfluidics and C. elegans as a model for studying neuronal pathfinding. On the Neurophilosopher’s blog.

Safe Passage: Lymphocyte Entry into the Brain – Infections in the brain are a problem, but so are overactive cytotoxic T-lymphocytes (CTLs) that combat those infections. The solution? Go check out Mystery Rays From Outer Space.

Another Way to Fuse Membranes – Membrane tethering and fusion has been a hot topic in cell biology for years, and so has ubiquitination. Here, Alex discusses a paper connecting the two, at The Daily Transcript.

More on Transcribed But Non-Translated RNA – “Frontloading” meets a better explanation for DNA error surveillance. At The Evolution List.

Culturing Life Review – A slightly disappointed reaction to the recent book on the history of cell biology. Such a book was much-needed, but Alex wanted more; I still plan to get it and form my own opinion though, and am looking forward to it. At The Daily Transcript.

Touchstone of Life Review – An even more disappointed view of a book on “molecular information, cell communication, and the foundations of life,” right here on Migrations.

Neural Migration: Mind the (Adherent) Gap (late addition) – The migration of neurons along radial glial fibres requires the adhesion properties of gap junctions, rather than their channel properties. At the Cell Migration Gateway.

Carnivals: I and the Bird #57, Gene Genie #15, Mendel’s Garden #18, Encephalon #31, Tangled Bank #88, Oekologie #9.
