Finding deletions and duplications in the human genome: Machine learning for diagnosis of genetic variations
A random-forest, machine-learning method for identifying copy number variation from exome-sequencing data. A forest of hundreds of decision trees is trained on a validated set of genetic deletions and duplication, the model built from these trees can then be used to accurately identify copy number variation in sample exome-sequencing data.

Game theory shows why stigmatization may not make sense in modern society
Before modern medicine, stigmatization may have been the most effective way humans had for dealing with the spread of infectious diseases. Now, a game theory model supports the idea that stigmatizing people who have a disease may cause more harm than good. Image credit: Pixabay
Linking health and population patterns via satellite
Penn State biologist Nita Bharti and geographer Andrew Tatem compared satellite images of nighttime lights over time to estimate population changes in places like Niamey, capital of the West African nation of Niger, and then correlated those changes with public-health records of measles outbreaks.
