by Christoph Weigel | Why should we consider this year's Nobel Prize in chemistry, and why in our 'Pictures Considered' section in the first place? A hint comes from one of the many press releases: "... for improving the resolution of optical microscopes." Aha! Microscopes are at the heart of microbiology since...
Vincent, Elio, and Michael reveal that a soil-dwelling nematode can recognize and respond to a bacterial quorum sensing molecule through a sensory neuron.
As is our custom at this time of year, we go over the material that has appeared in this blog over the last six months. Seems like a lot of stuff, but it’s the result of the work of quite a number of dedicated people, all of whom deserve our gratitude.
by Gemma Reguera | For over a century, microbiologists have been using growth media solidified with agar to culture microbes from environmental samples. Individual cells are easily separated on the solid surface, allowing each cell to grow and divide and form a colony of thousands of clones. We can change the nutrients in the media and physical parameters such as...
by Merry Youle | A variety of Bacteria, Archaea, and mobile genetic elements replicate their DNA as a linear chromosome using terminal proteins (TPs) to prime DNA synthesis, thus solving their end replication problem. As described in an earlier post, phage φ29 uses its TPs to also organize the sites of DNA replication for greater efficiency.
