Sigma Xi, is the world's largest international non-profit, multidisciplinary organization of science, technology, engineering, and mathematics (STEM) dedicated to research excellence, promoting public engagement with science, keeping the spirit of exploration and mentorship that defines scientific leaders. Notable former well-known members include Albert Einstein, Enrico Fermi, Linus Pauling, Richard Feynman, John Goodenough, and Jennifer Doudna.
Sigma Xi was founded in 1886 at Cornell University to honor excellence in science, and its name derives from the Greek phrase “Σπσσυδῶν Ξυνῶνες” (Spoudon Xynones) translating to “companions in Zealous research”. The society has more than 550 chapters around the world with more than 200 members who received the Nobel Prize and others nominated to various learned national and international academies of sciences. Sigma Xi, The Scientific Research Honor Society publishes American Scientist, and has its own Grants-in-Aid of Research program, with over 30,000 research grants awarded to graduate and undergraduate students since 1922.
Björn Brücher publishes with his colleague and friend, Dr. Ijaz Jamall, Sacramento, California a new plausible complex carcinogenesis and metastasis paradigm, entitled “Epistemology of the Origin of Cancer” for opening new ways of research, diagnosis and therapy. Their next fundamental paper will be shortly released by Cell Physiol Biochem, which adds an entirely novel understanding of cancer and metastasis. Björn founded the Theodor-Billroth-Academy®, and he and Ijaz serve at the non-profit Cancer Metastases Research Fund (CMRF) in Sacramento, CA, USA.
