This is not the case. The visual fields of the hammerhead's eyes do not overlap at all. Each eye presents the brain with a separate, completely different image to integrate. What, then, could be the purpose of the hammer head? No one really knows, but three suggestions are as follows: The head acts as a hydrofoil and gives the heavier-than-water, swimbladderless shark better swimming control. Grooves on the hammer head channel water toward the nostrils, providing "stereoscopic sniffing." The head is a platform for electromagnetic sensors that help locate prey. Stingrays are a favorite food of the hammerhead, and the shark may de-tect them electromagnetically, as surmised by the author of this article in the following encounters: "I have observed great hammerheads swimming close to the bottom, swinging their heads in wide arcs (a motion common, in a lesser degree, to all large sharks) as if using the increased electroreceptive area of their hammer like the sensor plate of a metal detector. Sometimes, these animals would doubleback to scoop up one of several stingrays hiding in the bottom silt. The minute electrical pulse that keeps the stingray's heart and spiracles operating betrays their presence to a hungry ...

Humphreys reviews a book that is just too expensive for us to consider buying. The title is: Synesthesia; A Union of the Senses . It costs $75 and is published by Springer/Verlag. The review, however, is expansive and provides some facts about synesthesia worth passing on to our readers. Syesthesia is an "oddity" of human perception in which words, musical instruments, objects, concepts, evoke sensations sharply different from what is actually being processed by the brain. For example, specific musical tones elicit specific color sensations; that is, B-flat evokes the color green; A-sharp, yellow, etc. Or the phenomenon may be more complex, with Mozart being green; Wagner, red, etc. Most "synesthetites" seem to experience colors, but geometrical figures sometimes appear in response to particular stimuli. As for the stimuli that call forth these exotic sensations; they are usually music or numbers. To some synesthetites, the cardinal numbers are associated with specific colors. The books's author is R.E . Cytowic, and he has provided some very interesting observations about synesthetites: There is much consistency among them; that is, if the number 5 evokes a red sensation with one, it does with most others, too. Also, synesthetites seem to run in families. Perhaps most ...

Levine and N.C . Gordon, of the University of California at San Francisco. The subjects were all dental patients who were tested when their surgical anesthesia was wearing off. The substances administered were: (1 ) a placebo; (2 ) morphine; and (3 ) naloxone, a substance that blocks the opiates produced in the brain. The doses were administered: (1 ) openly, when the experimenter knew which substance was being given; (2 ) by a person hidden from both experimenter and patient; and (3 ) by a machine. Two findings are particularly revealing. First, pain always increased after naloxone was administered, implying that the opiates blocked by naloxone are probably the same as those released by placebos. More significant, however, was the fact that both the open and hidden administrations of the placebo reduced pain while the machine-applied placebo resulted in more pain. In other words, when either the experimenter or the hidden administrator knew that the placebo was being given, the placebo worked. Levine and Gordon supposed that there must have been subtle clues, detected subconsciously by the patients, that the hidden person was administering the placebo. (Anonymous; "The Subtle Strength of Placebos," Science News, 127:25, 1985.) Comment. If no subtle clues existed, ...

Before an antivenin became available, this species killed one human every four years. It is not this low death rate that impels us to mention this spider. It is because the bite of the funnel web is deadly only to insects and humans. All other mammals are said to be immune. Analysis of the venom yields the remarkable fact that it consists of 45 active compounds. One of these is specific to insect brain cells; another, to human nerve cells. (da Silva, Wilson; "Spider Gives Kiss of Death to Pests," New Scientist, p. 23, May 17, 1997.) Comment. Since humans are not on the funnel web's menu, it must be only a coincidence that its venom kills people so selectively. It would be nice to know if chimps, gorillas, and orangs really are immune. A related phenomenon is seen in the venoms of cone shells. These snails are much more dangerous to humans, particularly naive shell collectors. Their venoms are extraordinarily complex and contain hundreds, perhaps thousands, of toxins. Many of these are specific to potential prey. Once again, humans are not on the menu but are included anyway. (Concar, David; "Doctor Snail," New Scientist, p. 26, October 19, 1996.) Comment. ...

Without question, some people can reproduce incredible blocks of words and numbers as well as drawings, music, etc. The question is: Is such exceptional memory the consequence of an exceptional brain or just long training? Those who hold the first position believe an anomaly exists because: (1 ) The difference between normal memory and exceptional memory is so large; and (2 ) People with exceptional memory seem to employ different mental processes in transferring information into long-term memory, notably visual techniques like 'photographic' memory. The authors of this article present several cases where subjects with normal memory have been trained to where they perform nearly as well as memory experts. The key seems to be the use of mnemonic devices and other methods of imposing some sort of order or meaning on the information involved. To illustrate, a chess master can usually recall the positions of all the pieces on a chessboard after a quick glance. But if the chessmen are arranged randomly and meaninglessly, his memory is reduced to near-normal. The gist is that long prac-tice and the application of mnemonic devices can vastly improve anyone's memory and, in consequence, memory prodigies are not really so anomalous. (Ericsson, K.

Oct 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The aye-aye, a percussive forager "The aye-aye, one of the strangest and rarest species of primates in the world, has an equally unusual method of finding food. Zoologists have discovered that it taps wood to locate cavities under the surface. Its skills are so well developed that it can tell holes containing grubs from those that are empty. It is the only mammal known to use such a technique." To improve the efficiency of its "percussive foraging," the aye-aye has evolved huge bat-like ears and a highly elongated middle finger on each hand. This specialized finger does the tapping and the big ears relay the nuances of sound to the brain. So sensitive is this specialized form of sonar that the ayeaye can detect grubs 2 centimeters below the surface of the wood. Once a grub has been located, the aye-aye tears into the wood with its forwardcurving, chisel-like teeth. The incisors are remarkable for a primate, for they keep on growing, just like those of rodents. When the grub-containing chamber has been reached, the long, narrow middle finger is inserted and the grub is retrieved. A neat combination of attributes. What is even more interesting is a comparison of the aye-aye with many of the woodpeckers. Many woodpeckers also employ percussive foraging, have special bills for chiselling, and possess very, spiny tongues for extracting grubs. In other words, the aye-aye is ...

This fish (different from the knife fish above) emits electric pulses at frequencies betwen 250 and 600 per second for electrolocation and communication. M. Kawasaki, at the University of Virginia, has investigated what happens when two of these fish operating on similar frequencies meet. Ordinarily, the fish would jam each other's sensory apparatus and "blind" each other. To circumvent this Eigenmannia has evolved a "jamming avoidance response," in which they both shift their pulse frequencies away from each other. To accomplish this, the fish must be able to detect time disparities between the two sets of signals less than 1 microsecond long. Their individual electroreceptors are not capable of handling such small time differences. Kawasaki has concluded that the jamming avoidance response can come only from highly sophisticated signal processing in the fish's central nervous system. (Kawasaki, Masashi; "Temporal Hyperacuity in the Gymnotiform Electric Fish Eigenmannia ," American Zoologist , 33:86, 1993.) Comment. Echo-locating bats and dolphins also possess sophisticated data processing apparatus for analyzing the echos they receive back from their prey and surroundings. It will be interesting to discover if evolution has come up with similar organic "components" for handling acoustic and electric signals. Further, we know ...

They can be very dangerous but in some cases they produce bizarre side effects. Take, for example, this case of a 61-year-old woman. The woman's symptoms began with nausea, fatigue and then disorientation. Then, after a year, she began hearing music in the forms of songs she knew. The music was peristent but kept changing. In December, it involved Christmas songs, for example. The songs were ones the woman learned when she was young. She had no obvious physical problems that might explain the hallucinations. The woman naturally went to a psychiatrist, but to no avail. Finally, repeated MRI examinations revealed two small brain aneurysms. When these were corrected surgically, the music stopped.

... , John; "Hidden Assets," Natural History, 93:75, October 1984.) Bats navigate by somehow constructing an image of the external world from the echoes of their squeaks. Since bats have but two ears, one wonders how they can develop a three-dimensional image from a two-dimensional sensor; ie., two ears give right-and-left information only. The moustache bat makes up for this deficiency by generating echo-locating pulses at three distinct harmonics: 30, 60, and 90 kilohertz. Its external ears are so shaped that each of these three frequencies has a different acoustic axis, giving the bat in effect three separate sets of ears pointing in three different directions. Inside the bat's head, in the inferior colliculus of the brain, are three sepa rate sets of neurons sensitive to the three different frequencies. No one knows how the bat processes such information into a "display" it can use in swooping after insects at night. (Anonymous; "The Ins and Outs of a Bat's Ears," New Scientist, 20, August 30, 1984.) Reference.

Illumination of these regions somehow encourages our pineal glands to release melatonin. D. Jones has suggested a more direct way in which light can reach the pineal gland -- through our ears! The pineal gland, which is believed to be the relic of the third eye that our distant reptilian ancestors possessed, is now buried deeply in our brains. But, it is possible that light could reach it through the ears by diffusing through the soft, translucent tissues that lead into our skulls. A commercial opportunity arises here. Jones notes first that melatonin is a mood enhancer and stimulant. We all have read how depressed far-northern peoples become during their long winter nights; and we know first-hand how exuberant we are on bright spring days. Why not, asks Jones, manufacture "earlights" mounted on headbands? These would direct red light (which diffuses better through tissue) into the ears and thence to the pineal gland. People could thereby be made cheerful and enthusiastic whatever the season, weather, or time of day. We could dispense with all those mood-enhancing pills.

Feduccia: "Calling this the original bird is irresponsible." (1 ) J.H . Ostrom: "Sad to say, for all its length, little support for the claim is to be found in this paper." (2 ) J. Gauthier: While some of the bones appear bird-like, they also look dinosaurian and could represent a new type of theropod dinosaur. (3 ) For his part, Chjatterjee asserts that Protoavis' skull has 23 features that are fundamentally bird-like, as are the forelimbs, the shoulders, and the hip girdle. "His reconstruction also shows a flexible neck, large brain, binocular vision, and, crucially, portals running from the rear of the skull to the eye socket -- a feature seen in modern birds but not dinosaurs." (1 ) Just why is there so much fuss over a handful of poorly preserved bones? If Protoavis is really a bird, it places the origin of birds 75 million years earlier and dethrones Archaeopteryx as a tran sitional link between dinosaurs and birds. In fact, Protoavis essentially denies that birds evolved from the dinosaurs. In short, Protoavis could change a limb or two on that Tree of Life you see in all the textbooks. References 1.

... ancient North America, but a century ago, when tiny graves replete with tiny skeletons were discovered in Tennessee, controversy erupted. Were they the bones of pygmies or children of normal-sized tribes? The latter choice was made, and we hear no more on the subject -- at least on the standard academic circuits. But a few reverberations are still detectable elsewhere. V.R . Pilapil, for example, asserts that the disputed Tennessee graves really did contain pygmy remains. Not only that, but he hypothesizes that the pygmies arrived in ancient times from southeast Asia, probably the Philippines, where today's diminutive Aetas live. To support his case, Pilapil recalls B. Fell's examination of the Tennessee skeletal material. Fell noted that: (1 ) The skull brain capacity was equivalent to only about 950 cubic centimeters, about the volume of a non-pygmy 7-yearold; (2 ) The teeth were completely developed and showed severe wear characteristic of mature individuals; and (3 ) The skulls were brachycephalic with projecting jaws. Fell had, in fact, described skulls very much like those of today's adult Philippine Aetas. Another line of evidence adduced by Pilapil involved the traditions of British Columbia tribes, which recognized a tribe of very small people called the Et-nane. More significant is the oral history of the Cherokees, which mentions the existence of "little people" in eastern North America.

... , gnats, and smart weapons In a thought-provoking letter to New Scientist, J. Margolis commences with the observation that calculating prodigies (idiot savants), who are often also mentally retarded, can easily and almost instantaneously recognize 20-digit prime numbers! Gifted mathematicians with so-called photographic memories cannot perform such mental feats using known methods for identifying primes. What do the calculating prodigies know that the rest of us do not? Better algorithms; that is, calculating methods? Margolis expands on this: "All this suggests some relatively simple, subconscious algorithms which have not, as yet, been explicitly formulated. Research in this direction might well result in new mathematical insights. "It need not be surprising that mathematical insight is more fundamental than language. Even a primitive animal brain is 'wired" to perform exceedingly complex computations essential for survival in an unpredictable environment. The latest 'smart' weapons are rudimentary compared with a humble gnat. Mathematics could be a by-product of these functions. Language is a comparatively recent evolutionary innovation and it is quite possible that conscious manipulation of abstract symbols has not caught up with an innate ability to perceive quantitative relationships."

... more friendly and relaxed than normal. He could not divine the reason until some months later when he decided to cover the flasks of skin-derived substances. Curiously, the lab workers soon reverted to their usual grumpy selves! What could account for this strange behavior change? Knowing that animals often communicated with one another employing chemicals called pheromones, Berliner suspected that the flasks had been releasing odorless human pheromones. Sure enough, analysis of the skin-derived materials proved him correct. Next: A Look Up the Nose. Biologists have long realized that animal noses actually contain two sensory channels. The first is the familiar olfactory system, which humans also possess. The second channel is the vomeronasal system. In animals, each system has its own separate organs, nerves, and bumps in the brain. The function of the vomeronasal system is pheromone detection. It was widely believed that humans had long ago discarded this sensory system along evolution's trail. But a closer look at the human nose by B. Jafek and D. Moran, affiliated with the Rocky Mountain Taste and Smell Center at the University of Colorado, revealed that all humans examined displayed two tiny pits on both sides of the septum, just inside the the opening of the nose. Behind the holes were tubes lined with unique cells that could well be pheromone detectors, since they responded positively to puffs of air laden with pheromones. In conclusion, we humans actually do have a sixth sense, and we are all enveloped in an aura -- not the luminous aura of the mystics but a cloud of pheromones ...

This is the human brain, of course. Not as widely appreciated for its versatility is the human vocal tract. It can generate much more than brute grunts. It renders operatic arias of great beauty and frequency range. The vocal tract can do even more than that; it can carry two musical lines simultaneously. This skill is called "throat-singing" or "overtonesinging." The best-known throat-singers live in the Tuva region of southern Siberia. The semi-nomadic herders of this wild region were evidently inspired to develop throat-singing so that they could better mimic the sounds they heard in nature: the singing of birds, the wind, the sounds of insects. Throat-songs have two components. The first is at a low, sustained fundamental pitch, which can be likened to the drone of a bagpipe. The second, superimposed on the low drone, is a succession of flute-like sounds that resonates high above the drone. It is the second component that can be controlled so as to mirror natural sounds. The result is like nothing Mozart or Verdi conceived. But it is an art form valued in Tuva and a talent rather remarkable from a biologist's perspective. One should compare the vocal ...

... all fakery. At the University of Heidelberg, 52 people with rotator cuff tendinitis were split into two groups; 25 were punctured with real needles, the rest just thought they were. In this experiment, the first group showed much greater improvement than those treated with the fake needles. Real acupuncture was more powerful than the placebo effect. Now if we can only figure out how real acupuncture works! (Lawton, Graham; "Needle Match," New Scientist, p. 10, December 4, 1999.) Placebo surgery. Because of the ethical questions, placebo surgery went out of style 40 years ago. A revival is now underway. One promising treatment for Parkinson's disease requires the drilling of holes in the patient's forehead and injecting fetal cells deeply in the brain. This is certainly a far cry from the fake acupuncture needles! One patient, who knew she was involved in a placebo experiment, was lightly sedated during the real drilling. After the holes were completed, she heard the surgeon ask for the fetal-cell implants. Because of this, she was certain she had received the complete procedure. Afterwards, she felt that her condition had definitely improved. But it was all a charade. The doctor did not insert the implants. Her symptoms soon returned. The placebo effect was only temporary. However, some of the younger patients who did get the total procedure did receive permanent benefits. The doctors knew, therefore, that the procedure holds out some promise.

... Costerton at Montana State University imagines what a biofilm would look like if one were bacterium-size. If you found yourself in a biofilm, you'd be going along a channel full of water, like the canals in Venice, and up from the bottom of the channel, on either side, would be these slime towers. The channels would be bringing in oxygen and nutrients. and removing waste. And within each building, so to speak, some of the bacteria would be cooperating with each other, making one compound and passing it along to the next. It's at least as complicated as a tissue. and possibly as a city. (Chicurel, Marina; "Slimebusters." Nature, 408:284, 2000.) Comment. Since bacteria have no brains, where do the building plans of this "city" reside? Nanocrystal aggregates. Even lifeless nanocrystals spontaneously form long, oriented chains. Self-organization is common in inorganic nature. Nanocrystals are clumps of atoms numbering in the hundreds, often thousands. Typically, nanocrystals are only 1-10 nano-meters long. Even so, they have a colonial spirit, and, like the tunicates and amoebas, they aggregate and self-organize. (( Alivisatos, A.P .; "Naturally Aligned Nanocrystals," Science, 289:736, 2000.) Comment.

... these days. Fox and his colleagues make microspheres by preparing a heated stew of various amino acids. These amino acids form long polymer chains spontaneously. Then, when water is added and the mixture reheated (or processed in some other way), the polymers organize themselves, again spontaneously, into spheres a few microns in diameter. Each sphere consists of a two-layer membrane with residual material trapped inside. Although thicker, the microsphere membrane is very similar to the lipid bi-layer enclosing normal living cells. The relatively stable microspheres could, in theory, have formed sheltered environments for the evolution of the more complicated parts of living cells. The microspheres absorb sunlight and, with the addition of this energy, display some of the electrical characteristics of biological neurons, like those in the brain. The implication is that some components of "mind" may have existed in the very earliest life forms. (Peterson, Ivars; "Microsphere Excitement," Science News, 125:408, 1984.) Comment. Two comments here: First, the word "spontaneous" is customarily employed when describing how atoms unite to form molecules and molecules combine into polymers, which then gather into microspheres. The word "spontaneous" seems to imply chance is operating rather than design. Actually, atoms and even subatomic particles must have innate properties which force them to combine into larger structures the way they do. Philosophically, one can ask whether the lowliest subatomic particles are "coded" to combine into molecules, microspheres, and living creatures. In other words, the design of life ...
