Friendship Paradox Redux: Your Friends Are More Interesting Than You

Feld’s friendship paradox states that “your friends have more friends than you, on average.” This paradox arises because extremely popular people, despite being rare, are overrepresented when averaging over friends. Using a sample of the Twitter firehose, we confirm that the friendship paradox holds for >98% of Twitter users. Because of the directed nature of the follower graph on Twitter, we a...

Are we sedating more than just the brain?

Heavy sedation in the ICU is associated with coma, delirium, and prolonged stays, but links between sedatives and non-brain organ failure have rarely been described. In a post hoc analysis, Strøm and colleagues explored associations between sedation and acute kidney injury among ICU patients randomly assigned to one of two sedation strategies. The 'no sedation' protocol was associated with less...

More ties than we thought

We extend the existing enumeration of neck tie knots to include tie knots with a textured front, tied with the narrow end of a tie. These tie knots have gained popularity in recent years, based on reconstructions of a costume detail from The Matrix Reloaded, and are explicitly ruled out in the enumeration by Fink and Mao (2000). We show that the relaxed tie knot description language that compre...

Does Biosynthetic Silver Nanoparticles Are More Stable With Lower Toxicity than Their Synthetic Counterparts?

Control of size and shape is a challenge in nanoparticle synthesis. Synthetic and biosynthetic (both extracellular and intracellular) methods are used to prepare silver nanoparticle (SNP). In this study, the behavior of three strains of Staphylococcus aureus (S. aureus) was investigated in the presence of silver nitrate intra- and extracellularly. S. aureus strains biosynthesized SNPs intracell...
