Microbiologists have been fascinated by the social swarming of the myxobacteria since they were first isolated by Roland Thaxter in 1892. Traveling in "wolf packs," these bacteria glide along solid surfaces, such as agar. En masse they secrete enough extracellular enzymes to lyse and digest bacteria...

Although sphingolipids have been known for more than 100 years, this class of body components is known by relatively few biological researchers. The lonely double bond between carbons C-4 and C-5 is very important to living beings...

Here's a Ralph Lewin story you might not know. Ralph and Mike Doudoroff (another polymath: student of butterflies and snakes as well as microbial metabolism and taxonomy) were great friends. At the annual Asilomar meetings, Mike and Ralph always hung out together and interacted to everyone's delight and mild apprehension.

Picture a leading authority on algal genetics and ecology, a discoverer of fascinating microbes from many phyla, an accomplished poet, an Esperantist who translated Winnie the Pooh into that language, a wit, a philosopher, and a nice guy. You have pictured Ralph Lewin, who died in La Jolla, California, in late November...

Wolbachia have caused one of the great pandemics in the history of life. They infect at least 20% of the species of arthropods – which adds up to about 106 species – as well as other invertebrate hosts. And they have done this using only maternal (vertical) transmission to infect their next host. Maternal transmission is...
