Models based on an average cell are useful, but they may not accurately describe how individual cells really work. New possibilities opened up with the advent of single-cell live imaging technologies. Now it is possible to peer into the lives of individual cells. In a new paper in PLOS Genetics, a team of biologists and physicists from Washington University in St. Louis and Purdue University used actual single-cell data to create an updated framework for understanding the relationship between cell growth, DNA replication and division in a bacterial system.
Simulations that help determine how a large-scale pandemic will spread can take weeks or even months to run. A recent study in PLOS Computational Biology offers a new approach to epidemic modeling that could drastically speed up the process.

Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent’s plants and wildlife by the year 2100, according to a study publishing December 22nd in the open access journal PLOS Biology.
Researchers have developed a novel machine-learning framework that uses scene descriptions in movie scripts to automatically recognize different characters’ actions. Applying the framework to hundreds of movie scripts showed that these actions tend to reflect widespread gender stereotypes, some of which are found to be consistent across time.
A brief roundup of news and story ideas from the experts at UCLA Health.
