Polywater’s Final Exit

“The extended-standing controversy more than the existence of a superdense, polymeric kind of h2o is evidently above. The argument commenced when Boris V. Derjaguin and colleagues at the Soviet Academy of Sciences observed that sure samples condensed in great capillary tubes represented a new, secure variety of h2o with a density virtually just one and a fifty percent occasions that of everyday drinking water and a molecular composition that could only be explained as polymeric. Subsequent investigations in the U.S.S.R., Britain, Germany and the U.S. argued that the anomalous attributes could be explained by impurities. Derjaguin has now described that new measurements by his group have unveiled that their samples invariably consist of trace impurities.”

Drunk Intestines

“Alcohol is made in the human intestine by microorganisms. The amount of pure ethyl liquor (the potable sort) made daily is about one particular ounce. Ethyl liquor ingested by a human, or produced in the intestine, is carried to the liver. In the liver 80 percent is damaged down by liquor dehydrogenase the remaining 20 p.c is possibly metabolized by another enzyme, catalase. It is the efficiency of the procedure that so prolonged masked the output of alcoholic beverages in the intestine. The microorganisms that create it continue being unknown.”

Persons with automobile-brewery syndrome generate much additional alcoholic beverages everyday and may well appear to be intoxicated even though they have not been ingesting.

The Jesus Lizard

“The basilisk lizard of Mexico and Central The us has a distinctive potential: it can walk on water. In some locations this capacity has earned it the title lagarto Jesus Cristo—the Jesus Christ lizard. Joshua Laerm of the University of Illinois photographed the animals with a large-speed camera. As the basilisk picks up pace, it twists the lower 50 percent of its entire body from a single side to the other and thrusts every leg backward and to the aspect. The consequence is a speedy waddle, required to press itself ahead with most drive and retract each leg from the h2o with a minimum of resistance.”

Sixteen Ohms of Malaria

“‘You have sixteen ohms of malaria,’ exclaimed the person at the rheostat, to a member of the Scientific American team who has been investigating the much-disputed Electronic Reactions of Abrams, a process of analysis and procedure produced by Dr. Albert Abrams of San Francisco. There are Period practitioners during the region. Outstanding cures are claimed to be effected, such as scenarios of cancer. But there are several doubters in and out of clinical circles. The public, hunting on, stays in a quandary.”

Era was a enormous healthcare hoax. It held that conditions have a exceptional vibration price that could be sensed from a fall of blood, or a handwriting sample, and handled, all with Abrams’s sealed electronic bins.

Superhuman Insects

“M. l’Abbe Plessis, in an posting in Les Mondes, says that he positioned a large horned beetle, weighing some fifty grains, on a clean plank, then additional weights up to 2.2 lbs .. In spite of this becoming 315 periods the beetle’s excess weight, the beetle managed to elevate it and move it together. A human is completely a hundred situations feebler in proportion. Equally, the flea, scarcely .03 of an inch in height, manages to leap over a barrier 500 periods its very own altitude. Visualize a human leaping 3,000 ft in the air!”

Fast Pigeons

“Carrier pigeons are being extensively analyzed, and some have proven a superb speed. The Ariel, a pigeon that received the $2,000 prize in the international contest in Belgium in 1871, attained the length between New York and Stratford, Conn., sixty-four miles, in thirty minutes. A different fowl, regarded as No. 6, created the journey in pretty much as rapid a time. The provider pigeon seems to have a memory for areas, coupled with a very sturdy attachment for its abode.”
