In 1944 Ling won the biology slot of the sixth Boxer Indemnity Scholarship, a nationwide competitive examination that allowed Chinese science and engineering students full scholarship to study in a United States university. In 1947 he co-developed the Gerard-Graham-Ling microelectrode, a device that allows scientists to more accurately measure the electrical potentials of living cells. In 1962 he introduced the Association induction hypothesis (see below), which claims to be unifying, general theory of the living cell, and is an alternative and controversial hypothesis to the membrane and steady-state membrane pump theories, and three years later added the Polarized-Oriented Multilayer (PM or POM) theory of cell water.
Ling, during 50 years of research from 1946, has carried out numerous scientific experiments that attempt to disprove  the accepted view of the cell as a membrane containing a number of pumps such as the sodium potassium pump and the calcium pump and channels that engage in active transport.
Early life and education
Ling was born December 26, 1919, in Nanking, China. He grew up in Beijing and entered the National Central University (Nanking University) in Chungking as a student of animal husbandry. After two years, he transferred to the biology department and received a Biology B.Sc. degree, minoring in physics and chemistry in 1943.
In 1944, having done graduate work in Biochemistry at the National Southwestern Associated University (National Tsing Hua University) in Kunming, Ling won the sixth Boxer Indemnity Scholarship. In early 1946 he began his graduate study in the Department of Physiology at the University of Chicago under Professor Ralph W. Gerard. In 1948 he completed his Ph.D on the effects of metabolism, temperature and other factors on the membrane potential of single frog muscle ﬁbers which was published in Dec 1949 in a series of 4 papers in the Journal of Cellular and Comparative Physiology, Volume 34, Issue 3. He spent two more years under Prof. Gerard as a Seymour Coman Postdoctoral Fellow.
From 1950-1953 Ling worked as an Instructor at the Medical School of the Johns Hopkins University in Baltimore. His research and experiments led him to the conclusion that the mainstream membrane pump theory of the living cell was not correct. This early embryonic version of the Association induction hypothesis was called Ling's Fixed Charge Hypothesis (LFCH).
From 1953-1957 he continued full-time research at the Neuropsychiatric institute at the University of Illinois Medical School in Chicago. Beginning as an Assistant Professor, he was promoted two years later to (tenured) Associate Professor-ship.
In 1957, he accepted the position of Senior Research Scientist at the Basic Research Department of the newly founded Eastern Pennsylvania Psychiatric Institute.
In 1962 his first book entitled "A Physical Theory of the Living State: the Association-Induction Hypothesis." was published. At this time Ling become director of a research laboratory at the Pennsylvania Hospital in Philadelphia and carried on research for the next 27 years with help from research assistants, graduate students and postdoctoral students — from the US and abroad.
In 1984, Ling published his second book, "In Search of the Physical Basis of Life," summarizing rapidly gathering new knowledge from his laboratory and other investigators.
In October 1988, Ling's laboratory shut down due to his inability to obtain research funds from National Institutes of Health and other funding agencies. Fortunately Ling's associate Dr. Raymond Damadian, a key figure in the MRI story and President of the MRI manufacturing Fonar Corporation, offered to support him and two of his staff: Margaret Ochsenfeld and Dr. Zhen-dong Chen.
From 1982 to 1985 he was a co-Editor-in-chief of the Physiological Chemistry & Physics and Medical NMR journal and since 1986, has been its sole Editor-in-Chief. In 1992 Ling published his third book, "A Revolution in the Physiology of the Living Cell." In 2001 his fourth book "Life at the Cell and Below-Cell Level"  was published and has been translated to Russian and Chinese.
In the summer of 2011 his wife of 60 years, Shirley Wang Ling, died from incurable pancreatic cancer. In 2014 at the age of 94 he published his fifth book, a reply to Erwin Schrödinger's 1944 book What is Life? called What is Life Answered He has published over 200 scientific papers in prestigious journals, although much of his later work has been largely ignored by the scientific community.
In 1963, Hodgkin with Huxley, won the Nobel Prize in Physiology or Medicine for their work on the basis of nerve "action potentials," the electrical impulses which enable the activity of an organism to be coordinated by a central nervous system. Hodgkin and Huxley shared the prize that year with John Eccles, who was cited for his research on synapses. Worldwide use of this new microelectrode spread rapidly after this and has subsequently proven to be one of the most important devices applied to the study of cellular physiology. The microelectrode in use today is essentially the same as this, except that it usually contains a concentrated salt solution, and is commonly referred to as the glass capillary. In 1950 Gerard was nominated for the Nobel Prize for helping to develop the microelectrode as used in Electrophysiology.
Association induction hypothesis
An alternative and controversial hypothesis to the membrane and membrane pump theories, the Association Induction Hypothesis is a claim related to the properties and activities of microscopic assemblies of molecules, atoms, ions and electrons of the smallest unit of life called nano-protoplasm.
Polarized-oriented multilayer theory
In 1965, Ling added his Polarized-Oriented Multilayer (PM or POM) theory of cell water to the Association Induction Hypothesis. The theory argues that cell water is polarized and oriented and thus dynamically structured.
More recent studies by Gerald Pollack (2001, 2013) and Mae-Wan Ho (2008, 2012) have confirmed the structured nature of cell water and some scientists such as Vladimir Matveev (2012) continue to explore the ideas that Ling introduced in the 1960s.
