Viruses can Network Also?

This summer was filled with big budget Hollywood flicks staring idolized heroes ranging from Thor to the Green Lantern to Jack Sparrow fighting evil forces threatening humanity.

Privacy Concerns With an Exanding Network

The Politics of the Public Opinion It is not difficult to prove that Facebook has revolutionized the modern friendship and has completely transformed the way information is spread. Although this is more often seen in social situations, now that businesses and companies can make Facebooks as well, this transformation is continuing to affect even more aspects of modern society.

Scale Invariance in Real World Networks

Source: In “Emergence of Scaling in Random Networks”, Albert-Laszlo Barabasi and Reka Albert show that a class of networks called “random networks” exhibits a phenomenon well-known to physicists and mathematicians: scale invariance. Scale invariance simply means that the overall features of our network look the same (at least statistically) under dilatations. Most of us are […]

The Dark Knight: Awesome movie. What makes it so great? Well maybe it’s Christopher Nolan’s blue-black imagery and talent for suspense. Or perhaps it’s Christian Bale’s ability to incapacitate Gotham City’s entire SWAT team while nursing the world’s worst sore throat. Who knows for sure? But I think (and I’m sure many people would agree) what […]

To spore, or not to spore? Surviving harsh environmental conditions is one of the principle barriers to optimizing fitness, or the ability to “pass on” genetic information to the next generation, that bacteria face. Bacteria constantly face “decisions” regarding how to deal with prolonged exposure to extreme (high or low) temperatures, concentration of oxygen, pressure, and pH. One common method […]
