Ignoring objections from traditionalists, Dr. Udupa has even initiated tests on rats that are made to simulate a yoga posture. Half a dozen field rats are doing one to two hours a day of sirasana or standing on the head, in openend glass tubes. Wires attached to their tails measure their pulse rate, blood pressure and other metabolic changes.

Stress induced in rats by electric pulses made them irritable and quarrelsome, but after an hour of sirasana they became tranquil and appeared to be contented, Dr. Udupa said.

Contagious urination, like other forms of behavioral and emotional state matching, may have important implications in establishing and maintaining social cohesion, in addition to potential roles in preparation for collective departure (i.e. voiding before long-distance travel) and territorial scent-marking (i.e. coordination of chemosensory signals)...

we find that in captive chimpanzees the act of urination is socially contagious. Further, low-dominance individuals had higher rates of contagion.

Marage employed, in his experiments, the larynx of the dog. In order to spare the animal useless suffering, morphine was first administered hypodermically and, three hours later, the dog was put under the influence of chloroform, and the larynx, with five or six rings of the trachea, was excised. A rubber tube of the diameter of the trachea was then connected with the latter by means of a short tube of thing glass, so that a current of cold air could be forced through the extirpated larynx. The pressure of the air was measured with a very sensitive metallic manometer graduated in millimeters of water pressure. The compressed air was stored in a rubber bag similar to those which are employed for inhalations of oxygen, and was kept at the temperature of 98.6 deg. F. The muscles of the larynx were stimulated by the current of a small induction coil, which was energized by a storage battery, and the sounds emitted by the larynx were recorded by a phonograph. The following conclusions were reached:

When the larynx of a dog is removed during chloroform anesthesia, the laryngeal muscles retain their ability to contract for a short period, which varies from 3 to 10 minutes, but no contraction can be produced in the muscles of a dead larynx, even if it is removed immediately after the death of an animal, because the arterial blood has escapes.

In order to produce the vibrations, the current of air should be impelled by a pressure of from 6 to 8 inches of water, as it is in the normal production of the human voice. In these conditions the excised larynx of the dog barks and howls in every note of the canine register, from the deep baying of a mastiff to the shrill pipe of a terrier. These various notes are obtained at will by causing various muscles to contract.

If you bet a dollar on the outcome of a coin toss (i.e., paying 1 dollar to enter, and winning either 0 or 2 dollars depending on the outcome) and repeat the bet 1,000 times, knowing the starting position of the coin toss would earn you 19 dollars on average. This is more than the casino advantage for 6 deck blackjack against an optimal-strategy player, where the casino would make 5 dollars on a comparable bet, but less than the casino advantage for single-zero roulette, where the casino would make 27 dollars on average.
