The “clanger cicada” can physically kill bacteria by poking and shredding them with tiny pointy structures that seem to look a little like an old fashioned cheese grater. Keep in mind that this happens at a very small spacial scale, so the relationship between objects is different than in normal human experience. Essentially, the membrane…

Primary Cilia Connect

Here is a press release from BioMed Central that is just so interesting I had to give it to you as it is without delay: Connecting cilia: cellular antennae help cells stick together Primary cilia are hair-like structures which protrude from almost all mammalian cells. They are thought to be sensory and involved in sampling…

Craig Venter and team make a historic announcement: they’ve created the first fully functioning, reproducing cell controlled by synthetic DNA. He explains how they did it and why the achievement marks the beginning of a new era for science.

Scientists are reporting that they have made a living cell from DNA that was originally synthesized in a lab. This isn’t quite a synthetic organism. But the result is an important, and some would say troubling step on the road to creating life in the lab. Craig Venter is the scientist behind the effort. Many…

It turns out I write academia erotica! I can tell you that the three dimensional visual imagery in the post to which Stephanie refers was a replacement for the actual visual imagery I had in mind when I wrote it. But I couldn’t use that because …

Diatoms Large and Small

Diatoms are algae with hard parts. They make up a major part of the plankton found in fresh and salt water environments. Usually, diatoms exist as single celled free floating organisms, but they can also be colonies of several single cells. Their tiny little ‘shells’ are made up of silica (these shells are called “fustules”).

I do not advocate this cookbook.

But it might be worth thumbing through it just for fun … You must be over 18 to read the rest of tis blog post. ————————- the fold —————————–

The original video couldn’t make it, so here’s a substitute teacher video:

Allen’s Rule. One of those things you learn in graduate school along with Bergmann’s Rule and Cope’s Rule. It is all about body size. Cope’s Rule … which is a rule of thumb and not an absolute … says that over time the species in a given lineage tend to be larger and larger. Bergmann’s…
