Bats have been found to evolve into bigger sizes in exactly the same way in separate locations, in a very rare example of parallel evolution. The findings come from a study of several bats—some very ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Convergent phenotypic evolution often results from similar genetic changes in independent species by a process known as parallel evolution. Sometimes, convergent evolution results from the evolution ...

Parallel evolution is the independent evolution of similar traits, starting from a similar ancestral condition. Frequently this is the situation in more closely related lineages, where several species ...

Mathematicians, it's a rainy day but Susanna Post, the 2021 Arkansas Teacher of the Year, is on the hunt. Can you help in her scavenger hunt to find examples of parallel and perpendicular lines? Rise ...

Parking is not always an easy task. Sometimes spots are too tight, too small or positioned strangely — not to mention the potential obstacles hindering your perfect parking, like other vehicles, trees ...

Take advantage of lock-free, thread-safe implementations in C# to maximize the throughput of your .NET or .NET Core applications. Parallelism is the ability to have parallel execution of tasks on ...
