Non-Photosynthetic Bacteria Also Have a Circadian Rhythm

by Elio | The very first entry in this blog, in December 2006, was about the amazing fact that some photosynthetic cyanobacteria have a circadian rhythm. I entitled it "It Don't Mean a Thing If It Ain't Got That Swing." Read more →

Interplanetary Biomining

by Elio | We are not short of evidence that microbes can survive in space for extensive times. A favored way to find out is to carry out often multinational studies by placing sample organisms on the surface of the International Space Station. Read more →

Unmasking an Ancient Scourge

by Ornob Alam | Nothing takes you back in time quite like DNA, not ancient documents, not cherished tales, not ageless chronicles. Anyone studying human history today must take stock of the remarkable information recorded in DNA. Major advances in DNA sequencing and its extraction from ancient bones and teeth now provide unprecedented windows into major events in human history... Read more →

Trans-Translation Part 2: Of Vibrios and Squids

by Janie | This New Year story begins with newly hatched baby bobtail squids. Each squid is translucent and barely the size of a grain of barley. As they swim around, the six pores on their heads ringed with mucus-coated cells snag passerby Vibrio fischeri from the water. Read more →

A Whiff of Taxonomy – the genus Psychrobacter

by Christoph | What could be more chill­ing than to de­viate for once from our mot­to to "...em­pha­size the un­usual and the un­ex­pected phe­no­mena" and ta­king a look at a, well, slightly bor­ing group of psy­chro­phil­ic bac­te­ria? The ge­nus Psy­chro­bac­ter − the pre­fix psychro- comes from the an­cient Greek ψυχρός for cold, frozen − con­tains about 40 de­scribed spe­cies of... Read more →

Underground Highways

by Roberto | This photograph, taken from our book Life at the Edge of Sight, shows a network of almost invisible fungal filaments which, like miniature highways, wind their way around peaks and form bridges over valleys all within a minute amount of soil. Read more →

Of Terms in Biology: Trans-Translation

by Janie, Christoph and John McCutcheon | This could become a very short explainer of the term "trans-trans­lation", as gi­ven by Vioque and de la Cruz in their mini­review:"Trans-trans­lation is a pro­cess found in all bac­te­ria, which con­tri­butes to the re­lease of ri­bo­somes that are stalled through a va­rie­ty of causes, for ex­ample when the 3' end of a trun­cated mRNA lack­ing a stop codon...

Having the bow and arrow might not be enough...

by Natália C. Drebes Dörr | Daily challenges in the life of mi­cro­sco­pic or­gan­isms are not that dif­fer­ent from those ex­per­ienc­ed by chee­tahs and ga­zel­les in the sa­van­nas. Bac­te­ria are usu­al­ly em­bed­ded in com­mu­ni­ties where they need to ac­tive­ly com­pete for food and space. Also, they are often under the at­tack of vo­ra­cious pre­dators such as bac­te­rio­pha­ges and pro­tists, which they fight... Read more →

Exploration, Streptomyces-style

by Roberto | The evolutionary trajectories of bacteria are great­ly in­fluen­ced by their re­pro­duc­tive suc­cess in chan­ging en­vi­ron­ments. Of course, this is not just about how fast bac­te­ria di­vide when con­di­tions per­mit growth but also how well they sur­vive in the ab­sence of growth. In ad­di­tion, an im­port­ant de­ter­mi­nant of the over­all fit­ness of a bac­te­ri­al lineage is... Read more →

Spy Gadgets

by Janie | Some bacterial enzymes have interesting character arcs. DNA poly­merase, courtesy of Thermus aquaticus, soaks up the limelight as an enzyme pulled out of bacteria and cata­pulted into molecular biology stardom. One enzyme that is certainly less-known is FbaB, which helps Strepto­coccus pyogenes adhere to and invade host cells... Read more →
