It is well known among professional trumpeters that playing high loud notes for more than a few seconds may cause dizziness or occasionally 'black-out.' Indeed, many leading orchestras carry an assistant or 'mate' to take over from the first trumpet in prolonged difficult passages...

Apart from the discomfort of occasional dizzy sensations or black-outs, trumpet players are not likely to come to any harm. Vasodilation from heat or previous hyperventilation will exaggerate the effects of a given intrathoracic pressure. It is better to sit than stand, but the strict supine posture, which would be better still, seems hardly feasible. For orchestras in severe financial difficulties it might be possible to dispense with the assistant or 'mate' if the trumpeter wore a pilot's pressure-suit, which could be surreptitiously inflated by a switch on the conductor's desk.

Aside from the physical problems, the chickens have social problems and psychological hangups, Johnson said.

"I guess 'embarrassed' is as good a word for it as any. You put one of them in with a flock of normal birds, and it huddles off in a corner by itself. The other birds won't have anything to do with it until they get used to it," he said.

"And then they're just not as active sexually. They will court and strut much more than the normal bird, but they don't mate as readily."

Dr. Alvan R. Lauer of Iowa State college sent here today a shiny red instrument of torture, designed apparently to give the ordinary, garden-variety motorist the everlasting willies. This device, which Dr. Lauer invented and christened the drivometer, insidiously reverses the usual laws of nature and turns them wrong side forward. The drivometer consists essentially of an automobile which doesn’t move, and a landscape which does, at 50 miles an hour. Imagine that, if you can! We couldn’t either, until the American Automobile association persuaded us to sit behind the wheel. The road twisted like a hula dancer – and we were supposed to steer down it, paying close attention to stop lights, warning signals, WPA men working, and hot dog stands. Never before have we had such a ride. We knocked a truck off the road. We ran down a farmer’s daughter and we wrecked his house. We whanged into a freight train, jumped across a mountain range, drove through a lake and smashed an ice cream shoppe into tutti-frutti. We tried to stop the thing, but everything we pressed made it go faster. We shifted into reverse and raced to the rear, bumping barns, beats and bicycles. Sadly shaking his head, Earl Allgaier, the AAA safety expert, turned off the current. He said we didn’t seem to be very well coordinated, somehow, but that he’d test us on his other machinery. This, together with the drivometer, will be taken on a nationwide tour beginning next week to prove to the average motorist that he’s got a lot to learn.

In 1947, a wildfire swept through Mount Desert Island and the laboratory, incinerating all but a scattering of the mice. Little was determined to rebuild, and donations of mice — all of them originally bred at Jackson — poured back to the lab from around the United States, Canada, and Great Britain. Among these was a new mutant, the dystrophic mouse that Coleman would use as his model for the study of muscular dystrophy. And two years later, another mutant suddenly appeared in the lab — a mouse with traits that would, some twenty years later, attract and hold Coleman's attention for the rest of his career.

An animal caretaker first spotted the creature huddled in a corner of its cage, grooming itself. It was furrier than most, but what really stood out was the size of the thing — it was hugely fat. The caretaker alerted doctoral candidate Margaret Dickie, who diagnosed the mouse as "pregnant." But there were problems with this theory. For one thing, the mouse never delivered a baby. And on closer inspection, it turned out to be male. The fat mouse ate three times the chow eaten by a normal mouse, pawing for hours at the bar of the food dispenser like an embittered gambler banging away at a recalcitrant slot machine. Between feedings it sat inert. It seemed to have been placed on this earth for no other purpose than to grow fat.

There had been other fat mice. The agouti mouse, named for its mottled yellow fur similar to that of the burrowing South American rodent, is, in its "lethal yellow" mutation, double the weight of the ordinary variety. But the fat agouti was svelte compared to the newcomer. This mouse was outlandish, a joke, a blob of fur splayed out on four dainty paws like a blimp on tricycle wheels. Rather than dart around the cage in mousy abandon, it was docile, phlegmatic, as though resigned to some unspeakable fate. Dickie and her colleagues christened the mouse "obese," later abbreviated to "ob," and pronounced "O.B.," each letter drawn out in its own languid syllable.

Cockroaches become magnetized because they contain magnetic particles that become aligned with an external magnetic field. These particles are trapped in a runny medium that has low viscosity in living cockroaches. But as soon as the creatures die, the medium begins to harden and its viscosity increases.

The Bruce Effect implied that every male mouse smells different to every other male mouse, at least to female mice, and that he produces a spectrum of odours that vary slightly between individuals of the same strain and differ markedly between individuals of different strains. With lateral thinking on how to prove their theory, Bruce and Parkes turned to Boake, a world famous perfumery.

Knowing how skilful perfumers must be in distinguishing between thousands of different odours, they persuaded some Boake representatives to visit NIMR for the purpose of smelling the mice. They invited them to sniff at pieces of cloth that had each been exposed to different cages of various mouse strains. The perfumers had no difficulty in distinguishing the different strains as all had a unique aroma; they even commented that four of the strains were quite similar – all of which had been bred from one original colony at Hampstead. They also noted that the CBA mouse strain, which was fairly new to NIMR, had a wonderful and pleasantly musky smell that could be of commercial interest in perfume manufacture!
