Another derivative is serum, from Latin serum ‘watery fluid, whey’.

My friend Pär, who designed this website, died suddenly on 15th October 2014, before he could finish programming this footer. He was one of the most intelligent people I have ever met, feeling passionately about the aims of the Alliance.
This website is now being developed in his memory, trusting that we could help others who are seeking to consummate the sacred marriage of science and mysticism, the greatest challenge of our times.
My deepest sympathy to his family and friends. May he now truly rest in peace.
