Networks of Beliefs theory integrates internal and external dynamics

Sciencedaily.com 

The beliefs we hold develop from a complex dance between our internal and external lives. A recent study uses well-known formalisms in statistical physics to model multiple aspects of belief-network dynamics. This multidimensional approach to modeling belief dynamics could offer new tools for tackling various real-world problems such as polarization or the spread of disinformation.

How do coexisting animals find enough to eat? Biologists unlock insights into foraging habits in Yellowstone

Sciencedaily.com 

Ecologists have long sought clarity on the dietary habits of different animal species. For scientists, it wasn't obvious how herbivores in Yellowstone National Park, who subsist on grasses, wildflowers and trees, could compete for enough of those foods to survive the winter. Over two years, with the aid of cutting-edge molecular biology tools and GPS tracking data, the researchers were able to determine not only what herbivores in Yellowstone eat, but also what strategies the animals use to find food throughout the year.

Researchers publish breakthrough study on how new genes evolve

Sciencedaily.com 

Findings suggest that new genes can form by repurposing fragments of ancestral genes while incorporating entirely new coding regions (the protein-coding parts of the DNA). This innovative concept bridges the gap between entirely new gene formation from noncoding regions and the more traditional model in which new functions can arise from duplicated genes.
