Children scream. I mean they scream. It is their major form of communicating with each other. It is never angry screaming — ...

Unified employer IDs and digital document verification for permissions can help create high-wage jobs by reducing regulatory cholesterol. Implement this without delay.

Rats have made the various aviaries at Singapore's only bird park their home and have been running amok in the bird ...

Kohntopp, who has led canine pathogen detection in Florida and California, is running her dogs through trials with Washington ...

Avian flu has been spreading across the United States since 2022, with several cases even being detected in humans,including ...

The same principle appears in tree branches as well. The precise calibration of branch diameter leads to a hallmark of fractal shapes called scale invariance. A scale invariance is a property that ...

The math that describes the branching pattern of trees in nature also holds for trees depicted in art—and may even underlie ...

The scale invariance in branch diameter dictates how much smaller a limb should be as it branches and how much investment a tree makes in a few thick branches versus many thin ones. Trees have evolved ...

The authors begin with Leonardo da Vinci's observation that trees limbs preserve their thickness as they branch. The parameter α, known as the radius scaling exponent in self-similar branching ...

The math that describes the branching pattern of trees in nature also holds for trees depicted in art—and may even underlie ...

Trees in nature follow a “self-similar” branching pattern called a fractal, in which the same structures repeat at smaller and smaller scales from the trunk to the branch tip. In the new study ...
