Auxin makes the spirals in gerbera inflorescences follow the Fibonacci sequence

Researchers have found that the spirals in gerbera inflorescences follow the Fibonacci sequence, with the number of left- and right-winding spirals determined by consecutive Fibonacci numbers. The study used X-ray tomography and confocal microscopy to examine how auxin levels influence the patterning of floral primordia.

The cascade to criticality

Quasiperiodic structures exhibit unique beauty and intriguing physics, but a lack of overarching framework hindered understanding. Researchers establish versatile tools for exploring quantum behavior in diverse quasiperiodic settings, demonstrating the strength of their approach to uncover new physical mechanisms.

Mathematics of plant leaves

A new mathematical model, EDC2, explains the peculiar 'orixate' leaf arrangement pattern of a Japanese plant, suggesting that older leaves have stronger inhibitory signals. The findings support the accuracy of the formula and shed light on the genetic and cellular machinery behind plant development.

Diverse natural fatty acids follow 'Golden Mean'

Researchers at the University of Jena discovered that naturally occurring fatty acids have a predictable number of structural formulas based on their chain length, following the Fibonacci sequence. This discovery enables accurate analytical processes in lipidomics, the study of all fats in cells and organisms.

A trillion triangles

Researchers from North America, Europe, Australia, and South America have solved the first one trillion cases of an ancient mathematics problem. The team developed a clever technique for multiplying large numbers, making it possible to calculate the area of right-angled triangles with whole number or fraction sides up to a trillion.

Mathematicians predict patterns in fingerprints and cacti

University of Arizona mathematicians have developed models to reproduce fingerprint patterns and explain the arrangement of repeated units in plants. The research found that patterns in nature, such as those seen in fingerprints and cacti, are influenced by forces imposed during ridge formation.
