Biochemists Flu Viruses Evolve
2017/10/24
Influenza viruses mutate rapidly, which is why flu vaccines have to be redesigned every year. A new study from MIT sheds light on just how these viruses evolve so quickly, and offers a potential way t...
As fins evolve to help fish swim,so does the nervous system
fins evolve fish swim nervous system
2017/4/27
The sensory system in fish fins evolves in parallel to fin shape and mechanics, and is specifically tuned to work with the fish’s swimming behavior, according to new research from the University of Ch...

Let’s say you’re a bee and you’ve spotted a new and particularly lucrative source of nectar and pollen. What’s the best way to communicate the location of this prize cache of food to the rest of your ...
Though present in more than 6,000 living species of fish, the adipose fin, a small appendage that lies between the dorsal fin and tail, has no clear function and is thought to be vestigial. However, a...
Topological conditions of scale-free networks for cooperation to evolve
scale-free networks Topological conditions evolve cooperation
2011/7/7
We employ evolutionary game theory to study topological conditions of scale-free networks for the evolution of cooperation. We show that Apollonian Network (AN) is a perfect scale-free network, on whi...
