Is a single colony “pure”?
Shrestha et al. find that a contaminating strain of Geobacter sulfurreducens persists even after repeated streaking of single colonies on solid media. The stowaway strain KN400 was not found by deep s... Read More
Rewiring genetic networks.
Finely tuned genetic networks shaped by evolution have allowed organisms to express specific proteins precisely spatially and temporally. Yet there remains a hugely unexplored evolutionary space. Here... Read More
Protons as post-translational modifications.
A group at UCSF is re-thinking the role of protonation in regards to protein function. Rapid, reversible, environmentally sensitive and enzyme-free, protonation seems to be an ideal post-translational... Read More
Statistically significant improvements to your data analysis.
Halsey et al. raise issue with the often cited but infrequently analyzed P value. The authors use random sampling to show that experiments with low statistical power often will give false negative res... Read More
Coal, Lignin, and Fungi, Oh My!
Worldwide coal deposits presently in use as an energy source were formed hundreds of millions of years ago as buried ligin from woody plants. However, the carbon burial rate sharply decreased at the e... Read More
Can new antibiotics avoid resistance?
Ling et al. present a new nonribosomal peptide antibiotic, teixobactin, that inhibits cell wall synthesis by interacting with the lipid precursors of the cell wall. No resistant mutants of Staph. aure... Read More
What are the risk factors for French hens contracting Salmonella?
Huneau-Salaun et al. studied 519 flocks of French hens to determine what factors increased risk for Salmonella. As expected, caged hens were more likely to have Salmonella contamination than their mor... Read More- 2 of 2
