Laurent Schwartz (born on 6 October 1958 in Strasbourg, France) is a French oncologist and scientist. He is a distant relative of his homonym the mathematician Laurent Schwartz.[citation needed]

Major achievements[edit]

  • Morphogenesis is a consequence of physical forces[1]
  • The vascular network formation is a consequence of the percolation of the blood flow[2]
  • Cancer stellar shape is a direct consequence of loss cell polarity[3]
  • Cancer is a metabolic disease[4] This has led to the discovery of a combination of well-established drugs which stop tumor growth in mice[5][6]
  • Tobacco toxicity is a direct consequence of CO2 poisonning[7][8]
  • Inflammation and hyperosmotic pressure are synonymous[9][10][11]
  • The cellular volume and the electrical charges are intertwined (with Clair Poignard and Frederic Campion).[12]

Biorébus[edit]

In 2004 he joined with others to start Biorébus, which is both a think tank and a pharmaceutical company, with the goal of contributing to a change in paradigm in cancer research.[13][14] It was established as a cooperative as a parallel to the Bourbaki group’s initiative in mathematics in the late 1920s, which was a collective pseudonym under which a group of (mainly French) 20th-century mathematicians wrote a series of books presenting an exposition of modern advanced mathematics. The Biorébus group (most of them from the École Polytechnique, École Normale Supérieure intermingled with physicians, biologists and philosophers) meet every month. It feels that the crucial need is not to produce more data but to organize them in order to simplify biology as to make it understandable. Its work has been on trying to establish the hypotheses that cancer (whatever its subtype) is a metabolic disease akin to diabetes, that inflammation (whatever its cause) is synonymous to increased osmolarity, and that the toxicity of tobacco is a direct consequence of carbon dioxide poisoning

Its continuing goals are to determine whether a combined metabolic therapy (Metabloc) can alleviate tumor growth in humans, to understand the link between cancer in the elderly and Alzheimer's disease, and to write in mathematical terms the similarities between biology and cellular electrical forces.
