100 years of crystallography

100 Years later: Celebrating the contributions of x-ray crystallography to allergy and clinical immunology.

Current knowledge of molecules involved in immunology and allergic disease results from the significant contributions of x-ray crystallography, a discipline that just celebrated its 100th anniversary. The histories of allergens and x-ray crystallography are intimately intertwined. The first enzyme structure to be determined was lysozyme, also known as the chicken food allergen Gal d 4. Crystall...

100 years of crystallography: the IUCr launches a comprehensive open-access journal, IUCrJ

IUCrJ is a fully open-access journal that aims to publish high-quality structural science papers. It has been launched for the International Year of Crystallography (IYCr2014).

Physics in 100 years

Here I indulge in wide-ranging speculations on the shape of physics, and technology closely related to physics, over the next one hundred years. Themes include the many faces of unification, the re-imagining of quantum theory, and new forms of engineering on small, intermediate, and large scales. When Leon Cooper, on behalf of Brown University, asked me to contribute to their 250th anniversary ...

100 years of sperm chemotaxis

Exactly 100 years ago, F.R. Lillie reported chemotaxis in animal sperm for the first time (Lillie, 1912). Chemo-taxis refers to the directed movement of a cell or organism to the source of a chemical gradient; the chemical agent that elicits this movement is called a chemoattrac-tant. Chemotaxis had previously been shown by Pfeffer (1884) for fern spermatozoids; however, attempts to demonstrate...
