Flowers are innately beautiful to the human eye, but how does a sunflower achieve its stunning disc of intersecting spirals or a daisy its delicate symmetry?
That was the question tackled by University of Calgary computer scientists, who have answered one of biologys enduring questions with an animated model that provides the most detailed simulation of how plants grow into recognizable shapes.
In the article "A plausible model of phyllotaxis" published in this weeks edition of the Proceedings of the National Academy of Sciences, University of Calgary PhD student Richard Smith and Computer Science professor Dr. Przemyslaw Prusinkiewicz, together with their collaborators from the Institute of Plant Science in Berne, Switzerland (Soazig Guyomarch, Therese Mandel, Didier Reinhardt, and professor Cris Kuhlemeier), present the first model to show how plants achieve phyllotaxis – the unique arrangement of lateral organs around a central axis that results in the spiral patterns seen in most plants – beginning at the molecular-level.

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
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...
The oceans are the largest global heat reservoir. As a result of man-made global warming, the temperature in the global climate system increases; around 90% of...
