Higher Flying Lowers Comfort

Posted Jul 6, 07 10:56 AM CDT in Business,  Science & Health 

(Newser) – Airline passengers routinely suffer from altitude sickness, and aircraft cabins are insufficiently pressurized to prevent it, a new study concludes. Altitudes of 8,000 feet above sea level result in 4% lower oxygen saturation in the blood, researchers found; cabins are often pressurized at the equivalent of 8,000 feet.

The result can be headaches, nausea, vomiting, and difficulty sleeping, especially on long-haul flights of 3 to 9 hours. Maintaining a cabin altitude of 6,000 feet or lower would reduce discomfort, the study concluded. But the higher level of pressurization would have a cost: decreased fuel efficiency, shorter lifespan of the airplane frame, and the necessity for more structural weight, scientists said.

When subjects in a University of Texas test were made to feel out of control, they saw more patterns that did not exist—whether images in a fuzzy picture or links between unconnected actions. Which is why people like investors and baseball pitchers, who rely on things outside their control, are often superstitious, NPR reports.

    Honeybees Do Puzzling 'Wave' to Scare Enemies Honeybees flip over en masse and reflect light with their bellies for a reason, scientists have found: It's to scare off enemies. Bee experts knew that giant honeybees in Southeast Asia flipped over by the hundreds or even thousands but only recently discovered they were warding off predatory wasps. What scientists don't know is how thousands of bees communicate fast enough to flip over in unison in 800 milliseconds. More »
