This experience convinced me that if proteins were indeed semiconductors, then evolution might have made use of this property in the nose. At the time, everyone was very excited by 'electronic noses' which detect odor-ants with thin strips of semiconductors. I felt what biologists usually feel: that if we can do it, evolution did it a billion years ago. In order to solve the structure-odour problem, which as we have seen is a biological one, you need to know at least three things: (1) biology, (2) structure and (3) odour.

He was also "impressed by the subtlety and speed of biological reactions, [and] proposed that proteins may be semiconductors."6 Certain strains of bacteria orient themselves to the Earth's magnetic field. They have been shown to contain microcrystals of magnetite, a black mineral form of iron oxide. Particles of magnetite are the smallest magnets occurring in nature. Small crystals of this magnetic substance are present in the brains of certain animals that require the ability to orient to the earth's magnetic field, such as homing pigeons, bees, and migratory fish.7 Researcher J.

D E Tissues with highly regular arrays of molecules include (A) rod and cone cells in the eye; (B) collagen molecules in connective tissue; (C) phospholipids in a cell membrane; (D) cross-section of muscle tissue showing actin and myosin molecules, and (E) DNA molecules in a chromosome1 This crystalline structure of the collagen molecules that make up your connective tissue has a remarkable property: it is a semiconductor. semiconductors are not only able to conduct energy, in the way the wiring system in your house conducts electricity very quickly from one point to another.

Russian Nobel prize winner Albert Szent-Gyorgyi postulated that protein cells act as semiconductors, preserving and passing along the energy of electrons as information.21 However, most of this research, including Gurwitsch's initial work, had largely been ignored, mostly because there was no equipment sensitive enough to measure these tiny particles of light before the invention of Popp's machine.

Besides many other properties, semiconductors are also able to store energy, amplify signals, filter another.2 In other words, the connective tissue system can also process information, like the semiconductor chips in your computer. Your connective tissue system is well suited for the task of conveying both energy and information, because it connects every part of your body to every other part.

It is a liquid crystal material and its components are semiconductors. . . . One of the semiconductot properties of connective tissue is piezoelectricity, from the Gteek, meaning "pressure electricity." Because of piezoelectricity, every movement of the body, every pressure and every tension anywhere, generates a variety of oscillating bioelectri-cal signals or microcurrents and other kinds of signals. . . .

The Restriction of Hazardous Substances Directive, or RoHS, requires that manufacturers remove four toxic metals —lead, cadmium, chromium, and mercury—that have been critical ingredients in hundreds of thousands of products in everything from computers and semiconductors to electric trains and cell phones. It also bans the use of polybromi-nated flame retardants, the same ones proposed for the POPS list by Norway and the European Union. All these substances are considered by the EU as having potent carcinogenic or neurologically toxic effects.

They are nanotechnology's ultimate multitaskers, acting as conductors, semiconductors, or insulators, depending upon how they're shaped. They're also amazingly strong: by weight, they have fifty times the tensile strength of steel, and in theory could be up to a thousand times stronger; at the same time, nanotubes can be very flexible ("deformable") without losing resiliency. When used in a composite material, they can increase its toughness, change its electrical behavior, and allow it to store energy. Nanotubes can be used to make sensors, light-emitting diodes, even computers.

From this intellectual collage, I had at long last gained a rudimentary understanding of electron behaviour in metals and in semiconductors, and I tried to apply it to the maxima problem. I felt that it must have something to do with the electrons in the metal. As we have seen above, electrons in metals sit in their energy levels like a liquid in a vessel, filling each one of them up to a definite energy.

At the time, everyone was very excited by 'electronic noses' which detect odor-ants with thin strips of semiconductors.

I spent several more intense seconds comparing and contrasting biomembranes with silicon semiconductors. I was momentarily stunned when I realized that the identical nature of their definitions was not a coincidence. The cell membrane was indeed a structural and functional equivalent (homologue) of a silicon chip! Twelve years later an Australian research consortium headed by B. A. Cornell published an article in Nature, which confirmed my hypothesis that the cell membrane is a homologue of a computer chip.

The basic working element of the optical computer is a tiny glass tower containing layers of semiconductors. A laser beam shines on the tower and releases electrons that get trapped in the semiconductors. Depending on the strength of the laser signal, the electrons turn the tower either translucent or opaque. A stronger laser is then shone onto the system, and it will be reflected either strongly (from the translucent tower) or weakly (from the opaque tower). This reflected signal is one bit of digital information ?yes or no, on or off.

Cadmium is a heavy metal used in many electrical and mechanical appliances, batteries, rubber and plastic, insecticides, photography materials, and semiconductors. It is a cumulative poison, which can build up in the body over many years and cause permanent kidney disease, sometimes high blood pressure, and sometimes increased calcium excretion that can worsen osteoporosis. Carbon dioxide is a colorless, odorless gas used in fire extinguishers and other chemical processes. Overexposure causes headache, dizziness, elevated blood pressure, and increased heart rate.

While the effects of advances in quantum physics on radar, television, and semiconductors were vividly clear, few biological advances produced much, if anything, in the way of new medicines. Although many considered the 1940s and 1950s the 'golden age of drug discovery,' mostly due to the development of antibiotics, vitamins, antihistamines, and the Salk polio vaccine, biology could take little of the credit. And when the pace of new drugs slowed again in the 1960s, the 'failure' of biological research bore some of the blame.

In electronics, thallium is used in power systems, such as batteries or semiconductors. It is also employed in optical lenses, photo film, jewelry, dyes and pigments, and fireworks. A bigger concern was its uses in pesticides and rodentocides, which were banned in 1975. Thallium sulfate was used with starch and glycerin to treat grains for poisoning squirrels and rodents. This led to some fatalities when humans mistakenly consumed some of that grain. Thallium is in low concentration in the earth's crust. Humans cannot tolerate much thallium in their bodies.

Without crystals, the field of electronics, semiconductors, and transistors could not exist. How do crystals grow? They emerge, as Aphrodite from the sea, out of a highly saturated solution. As the liquid cools or evaporates, the substance dissolved in it precipitates into a solid form of smooth surfaces. If the crystallization process in nature is slow and steady, the resulting crystals will be large and beautiful—gem-stones, diamonds, quartz.
