Taking it in: Bacterial Endocytosis

Most GFP proteins (little black dots) localize to the paryphoplasm (marked with "P").

In my high school text books, bacteria were primarily defined in terms of what they were not. “Bacteria don’t have a nucleus”, “bacteria don’t have mitochondria”, “bacteria are not capable of complex membrane trafficking” and so on. But such boundaries seem to blur as more and more “eukaryote specific” properties pop up in [...]

North Sea Genomes

Coral Evolution: From Socialists to Soloists

The solitary and appropriately named sun coral Tubastrea Faulkneri.

Last week’s blog post on the ancestry of the malarial plasmid attracted several insightful comments by Psi Wavefunction. One of the issues discussed was when exactly the malarial ancestor changed his lifestyle from being a coral symbiont to a coral parasite. This week I came across a paper in PNAS that shows [...]

Living fossils don't exist...

The horseshoe crab, while sporting an impressive pedigree, is NOT a 'living fossil'.

… except in Hollywood movies.

Let’s make this clear from the start, I don’t like the term “living fossils” at all. It’s as if we decided that certain species are second class organisms that should have gone extinct a long time ago. Unfortunately for me, the term regularly crops up in the popular scientific press. Especially [...]

While one child uses the money to fund a charity dedicated to fighting poverty, the other one uses it to start the crime syndicate he has [...]
