Moonshot Science—Risks and Benefits
mBio, 2016 Ever since the successful Apollo 11 Moon landing in 1969, a “moonshot” has come to signify a bold effort to achieve a seemingly impossible task. The Obama administration recently called for a moonshot to cure cancer, an initiative that has elicited mixed

Field Science—the Nature and Utility of Scientific Fields
mBio, 2015 Fields are the fundamental sociological units of science. Despite their importance, relatively little has been written about their emergence, composition, structure, and function in the scientific enterprise. This essay considers the nature of fields and

Impacted Science: Impact Is Not Importance
mBio, 2015 The journal impact factor (IF) exerts a tremendous influence on the conduct of scientists. The obsession with IF has been compared to a medical condition, sometimes referred to as “IF mania” or “impactitis.” Here, we analyze the difference between impact

Electrochemistry and Spectroscopy of Sulfate and Thiosulfate Complexes of Iron Porphyrins [PDF]
, 2002 The electrochemical and spectroscopic properties of the complex formed by the addition of thiosulfate to ferric porphyrins were examined. The NMR spectrum of the thiosulfate–ferric porphyrin complex was consistent with a high-spin ferric complex, while ...

Acidified and ultrafiltered recovered coagulants from water treatment works sludge for removal of phosphorus from wastewater [PDF]
, 2016 This study used a range of treated water treatment works sludge options for the removal of phosphorus (P) from primary wastewater. These options included the application of ultrafiltration for recovery of the coagulant from the sludge.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Method of Attaching Strain Gauges to Various Materials [PDF]
, 1988 A method is provided to bond strain gauges to various materials. First, a tape with an adhesive backing is placed across the inside of the fixture frame. The strain gauge is flatly placed against the adhesive backing and coated with a thin, uniform layer

The effect of oxidation state on the viscosity of melts in the system Na2O-FeO-Fe2O3-SiO2 [PDF]
, 1987 The viscosities of two melts in the system Na2O-FeO-Fe2O3-SiO2 have been measured as a function of oxidation state. The experiments were conducted by concentric-cylinder viscometry, on melts equilibrated with gas mixtures in a vertical tube, gas-mixing ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
