What does a physicist see when looking at the NFT market?

The market for collectible digital assets, or non-fungible tokens, is an interesting example of a physical system with a large scale of complexity, non-trivial dynamics, and an original logic of financial transactions. At ...

Study finds no evidence for fractal scaling in canopy surfaces across a diverse range of forest types

The complexity of forests cannot be explained by simple mathematical rules, a study finds. The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.

Unraveling a paradox of Himalayan glacier melt

One in five glaciers on Earth are covered with a layer of rocky debris. The presence of debris influences how glaciers melt. In the Himalaya, debris covers most large glaciers, and it is so thick that it should insulate the ...

Discovery puts a magnetic spin on neuromorphic computing

The word "fractals" might inspire images of psychedelic colors spiraling into infinity in a computer animation. An invisible, but powerful and useful, version of this phenomenon exists in the realm of dynamic magnetic fractal ...
