Why does reading in a moving vehicle cause motion sicbiess? — Eric Dickens, 1 senior English major Answer: For those ever-diligent studiers who are compelled to catch up on their reading during those few minutes spent traveling from point A to point B, I have some bad news: You are predators. What I mean is, while human eyes are meant to be able to focus on a point directly in front of them (pre sumably prey, but for college students this may more likely be a ham sandwich or a great pair of legs), your eyes are also extraordinarily sensitive to motion in your peripheral vision. This was originally designed to warn us of attackers from the side, but was also designed to correspond with the movement in our central field of vision. In other words, if you are moving forward, you should be able to see movement in our front and side vision. When you read while traveling in a vehicle, your cen tral vision tells you that you are stationary while your peripheral vision tells you that you are moving. Ac cording to an October 1999 article in the Journal of Post graduate Medicine, these contradictory signals, along with the sensations felt by the balance-sensitive organs of the inner ear, confuse your brain. (At this interval I would like to point out that, if you are reading this on the bus, it may be important to note that a properly-folded Battalion may serve as a suffi cient substitute for an air-sickness bag.) This confusion panics the brain into releasing the stress hormones that cause the muscles of the stomach to increase their movement rates from the normal three cycles a minute to as much as nine a minute. At this point, you may blow chunks. According to information from Dr. A. Gregory Tol er Jr., a fellow in the Virginia Academy of Optometry, about 38 percent of the population is born without the ability to read in a moving vehicle under any circum stances other than while medicated. Those whose hormones are already up in arms, such as pregnant women and children (everyone un dergoes hormone readjustments from infancy to post adolescence), are also at higher risk to experience mo tion sickness. However, for the rest of us who are sometimes just a little queasy, turning away from the window while read ing in a car will help with the motion sickness. It’s that simple. If you are interested in further information, or if you have another question about how or why something hap pens, send me an email at scifyi@hotmail.com and I will see if I can regurgitate an answer. . HAMILTON, Ontario (AP) — Preliminary tests show that a Con golese woman who arrived in Cana da and fell ill with symptoms of a hemorrhagic virus does not have Ebola, a doctor said Wednesday. • It was not yet clear what the 32- year-old woman was suffering from. Dr. Mark Lobe said at a news conference at Henderson Hospital in Hamilton. “This greatly reduces the likeli hood that this patient has been infect ed with the Ebola virus,” Lobe said. Further tests were being conducted. The woman, who has not been- identified, was admitted to the hos pital Sunday drifting in and out of consciousness, doctors said. Earlier, a health ministry official said doctors diagnosed her as hav ing a low-grade case of malaria and were still testing into the possibili ty of a sort of hemorrhagic fever. Blood samples were sent to a Winnipeg laboratory and the U.S. Centers for Disease Control and Prevention in Atlanta, said Rosalyn Trembly of Health Canada. Results were expected Thursday. Ebola has never been confirmed in humans in North America. The woman was in serious con dition but was showing signs of im provement, said Lobe, an expert in infectious diseases. She arrived Saturday at Toron to’s Pearson International Airport on Air Canada Flight 735 from Newark International Airport in New Jersey, airline spokeswoman Laura Cooke said. The flight had 39 passengers and five crew members. Her flight had arrived in New Jer sey from Ethiopia, but it was not clear how she got to Ethiopia from Congo, The Toronto Star newspaper <6 This greatly ces the likelil re duces the likelihood that this patient has been infected with the Ebola virus. ” — Dr. Mark Lobe Henderson Hospital ■D/4JNCE 4 11 I ■ ■ !nK, Sroeeials TTitirsday-$l BAR DRINKS & LONGNECKS till 11:00 Friday & Satruday- $2 BAR DRINKS & LONGNECKS till 11:00 NO Cover For 21 and Up NO Cover with College ID! 18 & Up Welcome GEANL OPENING Thursdav* Feb. 8 Located at Texas Ave. and Southwest Pkwy. in Park Place Plaza (next to 4.0 & GO) flight, but also “advised us they; 11° 'd' reported. She apparently came to Canada on a legitimate visitor’s visa. Lobe said the woman’s symp toms were “possibly compatible” with hemorrhagic fevers. Doctors said she had not shown signs of bleeding from the ears, eyes or mouth — conditions that would suggest the Ebola virus that can be lethal in more than 50 per cent of cases. A recent outbreak in Uganda killed 173 of the more than 400 people who fell ill. Tests for meningitis — an infec tion of the fluid of the spinal cord and brain — have so far proved negative, doctors said.
