bacteria, virus and epidemics

How Bacteria in Our Bodies Protect Our Health

Researchers who study the friendly bacteria that live inside all of us are starting to sort out who is in charge—microbes or people?
Biologists once thought that human beings were phys­iological islands, entirely capable of regulating their own internal workings. Our bodies made all the enzymes needed for breaking down food and using its nutrients to power and repair our tissues and organs. Signals from our own tissues dictated body states such as hunger or satiety. The specialized cells of our immune system taught themselves how to recognize and attack dangerous microbes—pathogens—while at the same time sparing our own tissues.

Epidemiological research:

The Future Of Facebook [Research]

Some real research conducted by real rocket scientists, John Cannarella and Joshua A. Spechler, from Princeton’s Department of Mechanical and Aerospace Engineering in their article,Epidemiological modeling of online social network dynamics”.

Facebook’s future, the research

Cannarella and Spechler used epidemiological models to explain social media user behavior where adoption was analogous to infection and abandonment was analogous to recovery. 
Their model suggests Facebook has already reached the peak of its popularity. They conclude that Facebook has entered a decline phase, as shown by a downward trend in search frequency since 2012. Extrapolating the best fit model into the future, they predict Facebook activity will rapidly decline over the next few years.

'Princeton University will shut down'

Facebook data scientist Mike Develin has decided to use similar methods to give Princeton a taste of its own medicine and “prove” that Princeton’s enrollment will crash all the way to zero in less than a decade.
