• Bac­te­r­ial Blues

    by Janie — The color blue is an odd­ity. Of all pig­ments in na­ture – chem­i­cals that se­lec­tively ab­sorb and re­flect cer­tain wave­lengths of vis­i­ble light – blue ones are among the rarest. Pro­ducing blue dyes was once such a costly busi­ness that me­dieval Eu­ro­peans consid­ered it to be as pre­cious as gold...

  • A Case for Col­ors

    by Lizah van der Aart — Last year, Gilles van Wezel and Chang­sheng Wu an­nounced the dis­cov­ery of a com­pound with a com­pletely novel chem­i­cal back­bone, Lug­duno­mycin. This is an ex­cep­tional feat as we hardly find com­pounds with com­pletely novel chem­i­cal struc­tures. This is even more in­cred­i­ble if you con­sider how it was found. Bac­te­ria don't al­ways...

  • Sec­ondary Metabo­lites

    by Andy Bod­nar, Michelle Pri­eto, and Car­leen Vil­lar­real — The war be­tween bac­te­ria and phages has been wag­ing for eons longer than hu­mans have ex­isted. Con­se­quently, many bac­te­ria have de­vel­oped novel and unique ways for de­fend­ing them­selves against these for­eign in­vaders. Some change their sur­face pro­teins to pre­vent de­tec­tion, like chang­ing a lock on a door. Oth­ers give their own lives, ini­ti­at­ing...

  • Bac­te­ria Ac­ti­vate Fun­gal Gene Clus­ters

    by S. Mar­vin Fried­man — Fungi are no­to­ri­ous for their abil­ity to pro­duce a wide va­ri­ety of sec­ondary metabo­lites, in­clud­ing an­tibi­otics, statins, im­muno­sup­pres­sants, my­co­tox­ins, and oth­ers. A ver­i­ta­ble phar­ma­copeia. In­ter­est­ingly, many of the gene clus­ters in­volved in the biosyn­the­sis of these com­pounds are silent un­der nor­mal lab­o­ra­tory con­di­tions. In some cases, the syn­the­sis of these…
