Residents living in the shadows of wind turbines say the sound is making them sick. But so far the science isn't there. From NOVA Next | Jun 27, 2018 Thirty Years Ago Today, Global Warming First Made Headline News On June 23, a NASA climate scientist, James Hansen, told a U.S. From NOVA Next | Jun 23, 2018 New Middle Eastern Particle Accelerator’s Motto is “Science for Peace” In a region in turmoil, an unprecedented joint venture of scientists and policymakers is working together on Jordan’s new particle accelerator under the motto "science for peace.

MicrobeLibrary: premier visual resources and protocols used in teaching microbiological and biological sciences. Protein Data Bank. A Structural View of Biology This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease.
As a member of the wwPDB, the RCSB PDB curates and annotates PDB data. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond. Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states.

Paper Models of Polyhedra. DNA and Phi, the Golden Ratio, in the dimensions of its spirals. The DNA spiral is a Golden Section The DNA molecule, the program for all life, is based on the golden section.
It measures 34 angstroms long by 21 angstroms wide for each full cycle of its double helix spiral. 34 and 21, of course, are numbers in the Fibonacci series and their ratio, 1.6190476 closely approximates phi, 1.6180339. B-DNA has spirals in phi proportions DNA in the cell appears as a double-stranded helix referred to as B-DNA.This form of DNA has a two groove in its spirals, with a ratio of phi in the proportion of the major groove to the minor groove, or roughly 21 angstroms to 13 angstroms.
Insight on B-DNA proportions contributed by Melih Yazici. The DNA cross-section is based on Phi It has been reported but not yet confirmed by this site that a cross-sectional view from the top of the DNA double helix forms a decagon: A decagon is in essence two pentagons, with one rotated by 36 degrees from the other, so each spiral of the double helix must trace out the shape of a pentagon.
