    Originally called the "Lie Detector" and sometimes the "Lie Box," the polygraph does not detect lies, it detects emotional responses. In other words, the polygraph is a multichannel recorder that displays respiration, the pressure in a partially inflated arm cuff (which indicates a change in blood pressure and pulse rate), and a change in skin resistance. The history and the value of the polygraph are discussed. Although not providing admissible evidence in court, the polygraph has a role as a useful tool in directing an investigator where to seek further information. Equally as important as the development of the technology was the development of the type of question to be asked. If polygraphic information is not admissible as legal evidence, what value is the examination? There are three principal benefits: 1) it can eliminate a subject as a suspect, 2) the answers to questions can indicate in which direction further information is needed, and 3) the willingness to undergo an examination conducted by an approved, experienced examiner, chosen by a law-enforcement agency, provides evidence that the suspect has nothing to conceal. However, beyond its use in criminal investigation, it is widely used as a screening tool by employers. View full abstract»

  • The case for large-size mutations

    Charles Darwin's (1809-1882) On the Origin of Species was published around 140 years ago. Is it possible that something has been overlooked despite the thousands of research reports (including legal briefs and pseudoscientific nonsense) that have appeared on the subject? In the present essay it is claimed that there has been a bias against "large-size" mutations. My purpose here is to show that large-size mutations are inevitable. The answer to the question 'Are the large mutation sizes valid?' is 'yes' for two reasons: First, the fact that humans have evolved from humble beginnings 3.8 billion years ago does not prove, but surely testifies to the fact, that large mutations are sometimes viable. Second, a more convincing argument is that there are no laws of physics or chemistry that forbid large mutations; they are rare but allowable and, sometimes, they are viable. If so, they follow the mathematics of a Poisson "point process." As many writers have pointed out, evolution is a general organizing principle that applies to everything in the universe. It is tempting to conjecture that large evolutionary changes can be viewed as large "mutations.". View full abstract»

    Poiseuille, known for his law of fluid flow, which is the analog of Ohm's law, introduced the units (mmHg) by which we measure blood pressure by using the mercury manometer, which he described in his medical school thesis in 1828. For 50 years, mean blood pressure was all that could be measured because of the long response time of the mercury manometer. It is true that the height of the mercury column displayed pulsatile oscillations, but their amplitude was much less than that of pulse pressure. It is interesting to note that the slowly responding mercury manometer was made to display first systolic then diastolic pressure by means of an ingenious device that contained two oppositely directed check valves. It took from 1828 to 1903 for high-fidelity graphic recordings of blood pressure to appear in which systolic and diastolic pressures were believable. However, systolic and diastolic pressures were measurable since 1878 when Golz and Gaule created their ingenious valved device that permitted use of the slowly responding mercury manometer to display these pressures accurately.

  • The "on-sale" defense

    What happens when a company starts to explore selling an invention before a U.S. patent application has been filed? That was the question before the Court of Appeals for the Federal Circuit (CAFC) in the recent case of Group One v. Hallmark. The court rejected Hallmark's "on-sale" defense and held that Group One's patents were not invalid for violating the grace period. It thus sent the case back to the district court for a full trial of Group One's charge of infringement. View full abstract»

    This article discusses the innovations which made it possible to do single-channel recording and to study the release of chemical ions from a single channel in the cell membrane. Topics covered include: Herbert Gasser's use of electronics; Detlev Wulf Bronk as scientist and supporter of science; Hodgkin and Huxley probing inside the nerve; synaptic chemical transmission and quantum release; and inhibition and excitation in the horseshoe crab eye View full abstract»

  • Stem cells: new hope for the therapy of lethal diseases?

    The supply of donated organs and tissue that are used to treat diseases and disorders is far outnumbered by the need. Recently, there has been a lot of interest in the use of stem cells to treat such disorders, because these cells have a large proliferative potential while they can differentiate into every cell in the body under the appropriate stimuli. Recent reports on applications to Duchenne Muscular Dystrophy and myocardial infarction from the University of Pittsburgh and the University of Dusseldolf have provided some evidence that autologous or homologous stem cell transplantation could one day treat lethal human diseases. In addition to these uses of stem cells, there is research evidence that stem cells can be potentially used to treat spinal cord injury, burns, osteoarthritis, diabetes, Parkinson's and Alzheimer diseases. There are, however, many controversial issues, involving ethics, science, politics, and religion, associated with stem cell research from sacrificed human embryos View full abstract»

    The 50th anniversary of the IEEE Engineering in Medicine and Biology Society (EMBS) is an appropriate time to look back at the origins and growth of both the field of biomedical engineering and the EMBS. The present account gives most attention to the aspects of biomedical engineering to which IEEE members (and, earlier, American Institute of Electrical Engineers (AIEE) members and Institute of Radio Engineers (IRE) members) contributed, which is to say that this account emphasizes the electrical, electronic, and computing aspects of biomedical engineering. Topics covered include: history of the technologies; the roots of biomedical engineering; prehistory and history of the profession; biomedical applications of the computer; health care; ultrasound technology; new means of medical imaging; endoscopy, lasers, and fear of electromagnetic fields; study of human metabolism; the Human Genome Project, robotics, and internationalization; and forecasting progress in biomedical engineering.
