Regulating vitamin B12 biosynthesis via the cbiMCbl riboswitch in Propionibacterium strain UF1 [Microbiology]

Vitamin B12 (VB12) is a critical micronutrient that controls DNA metabolic pathways to maintain the host genomic stability and tissue homeostasis. We recently reported that the newly discovered commensal Propionibacterium, P. UF1, regulates the intestinal immunity to resist pathogen infection, which may be attributed in part to VB12 produced by…

Smallholder farmers and contract farming in developing countries [Agricultural Sciences]

Poverty is prevalent in the small-farm sector of many developing countries. A large literature suggests that contract farming—a preharvest agreement between farmers and buyers—can facilitate smallholder market participation, improve household welfare, and promote rural development. These findings have influenced the development policy debate, but the external validity of the extant…

Excessive antibiotic prescriptions for children in low-, middle-income countries

Between 2007 and 2017, children in eight low- and middle-income countries received, on average, 25 antibiotic prescriptions from birth through age 5 — up to five times higher than the already high levels observed in high-income settings. The number of antibiotic prescriptions for young children ranged from one per year for children in Senegal to 12 per year for children in Uganda.

Study: You can have empathy and still be a psychopath

People who score high in the personality traits narcissism, Machiavellianism and psychopathy can empathize, but generally lack the disposition to do so, according to a recent study. These traits are part of the "dark triad" of personality, which has been used to study malevolent personality traits since 2002. The results suggest it might be possible to encourage psychopaths to empathize more, but

Following the lizard lung labyrinth

Birds and mammals are on extreme ends of the airflow spectrum. Mammals inhale oxygen-rich air and they exhale depleted air, exhibiting a so-called tidal flow pattern. In contrast, bird breath travels tidally through part of the respiratory system, but in a one-way loop throughout most of the lung. University of Utah biologists have discovered that Savannah monitor lizards have lung structures that
