Chaotic "Lévy walks" are a good strategy for animals

A study published in PNAS explains how Lévy walks, a type of chaotic movement, allow animals to balance exploration and exploitation. The model used by the author shows that these movements emerge near critical points, enabling animals to respond strongly to environmental stimuli.

Walking the walk: What sharks, honeybees and humans have in common

A study by University of Arizona anthropologist David Raichlen found that human hunter-gatherers use a Lévy walk pattern while searching for food, similar to sharks and honeybees. The pattern involves short movements in one area followed by longer treks to another area.

Tracking criminal movement using math

Researchers develop Lévy flight-based model to analyze criminal movement, revealing optimal strategy for maximizing crime hotspots. The model provides insights into the relationship between step sizes and hotspot formation, shedding light on the complex dynamics of burglary hotspots.

Animal behavior study overturned

Researchers analyzed high-resolution data from loggers on wandering albatrosses' legs, showing they land on the water at simpler random intervals. This challenges previous findings about Lévy flight behavior in animals like deer and bumblebees.
