Editor’s Selections: Trypanosomes love social networking, a radical source of antibiotic resistance, and snakes interruptedFebruary 19th, 2010 Editor's Selections 12 Comments
Vincent Racaniello selects several notable posts each week from molecular and cellular biology and virology. He blogs at virology blog.
- The procyclic form of African trypanosomes move together as a group when grown on a semisolid surface. This social motility, mediated by the flagella, is a surprising new feature in trypanosome biology.
- Bactericidal antibiotics may cause cell death, irrespective of the initial cellular target of the drug, by stimulating the production of hydroxyl radicals, a reactive oxygen species . The hydroxyl radical damages cellular DNA, proteins and the cell wall, leading to cell death.
- For wildlife like the timber rattlesnake, trying to cross country roads is a life-or-death challenge. Such roads contribute to the genetic decline of the species.
I’ll be back next Friday with more selections.
