Img 1 (above): Human fingerprint patterns are created because basal skin grows faster than surface skin, which then buckles, forming ridges .
Img 2 (below): Kuecken developed a mathematical model that can reproduce fingerprint patterns, like this one.
Shipman found that cactus stickers predicatably align in spiral patterns
Patterns in nature can be seen every day, yet in many cases, little is understood about how and why they form. Now University of Arizona mathematicians have found a way to predict natural patterns, including fingerprints and the spirals seen in cacti.
UA graduate student Michael Kuecken developed a mathematical model that can reproduce fingerprint patterns, while UA graduate student Patrick Shipman created a mathematical model to explain the arrangement of repeated units in various plants. Shipman’s report on his work will be published in an upcoming issue of Physical Review Letters.
Even though the use of fingerprints for identification began more than 2000 years ago in China and they have been studied experimentally for over two hundred years, there is no widely accepted explanation for their occurrence. Likewise, the reasons behind nature’s choice of patterns in plants have been difficult for mathematicians to explain, despite these patterns having been identified centuries ago.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
