Cells Weekly #46

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.

Robert Hooke’s Long Lost Notes Published Online – Mo announces the online publishing of these notebooks, which include the first mention of the term ‘cells,’ which Hooke used to describe the features he saw in cork.
The Neurophilosopher’s Blog

Interference Inteference – Keith explains some findings on how siRNA does not work by magic, but rather by utilizing built-in cellular machinery.
Omics! Omics!

Signal Recognition Particle – Larry reviews the SRP, which is an important cellular component and it plays a crucial role in protein synthesis and protein trafficing.

The 2007 Nobel Prize in Physiology or Medicine: A Primer – Matt describes the science behind discoveries of principles for introducing specific gene modifications in mice by the use of embryonic stem cells.

Freak of Nature – BK vents some frustration, while describing recent experiments with siRNA.
Life of a Lab Rat

Integrin Adhesiveness: May the (Shear) Force Be With You – Kim covers recent research on how immobilized chemokines promote T-lymphocyte migration in a shear stress-free environment, but induce integrin activation and adhesiveness in the presence of external shear forces.
Cell Migration Gateway

Casting a Beady Eye on Kinases – Keith discusses some strategies for identifying drug targets aimed at kinases, which are critical signaling molecules in cells controlling such problems as malignancy.
Omics! Omics

No Homolog or Weak Homolog? – While most science bloggers just discuss the published results of science, Rosie Redfield brings us the gritty details of science in progress, post after post after post. It’s good reading if you’re curious about the problem-solving that you’d be doing if you became a molecular biologist.

How to Prepare Brain Slice Cultures – Mo links to a comprehensive online database of research techniques for the life sciences.
The Neurophilosopher’s Blog

Evolution of Meiotic Genes: The Case of Spo11 – There’s no shame in self-promotion: John mentions a paper on the genes of a particular cellular process.
Sex, Genes & Evolution

A Shining Mystery – Moselio discusses a bit of a mystery, in a bacteria who has a light sensor, and the expression of some of its genes are controlled by light.
Small Things Considered

Cooperation and Cheating in Microbes: Quorum Sensing and Persisters – Ford explains some of the issues and questions surrounding how bacteria signal to each other to cooperate during infections.
This Week in Evolution

Par-Tiam1 Complex: Persistently on Par – Kim describes some recent findings on how a critical protein complex affects microtubule stability to control cell polarity, chemotaxis and persistent cell migration in skin cells.
Cell Migration Gateway.

Epitope Prediction: The Seven Percent Solution – Ian opines about the difficulties in, well, epitope prediction… a vital thing is you’re a cytotoxic T-lymphocyte (CTL).
Mystery Rays from Outer Space

Know Your Cell Structures – And lastly, I had a recent post where I try to explain, in simple terms, a couple structural and evolutionary concepts with actin polymerization as a model.

Adult Stem Cells are not Interchangeable With Embryonic Stem Cells – Late addition (sorry, I forgot that I bookmarked this one) – Mike debunks the Right’s argument that adult stem cells are as or more promising than embryonic stem cells.
