Officials with the Knox County Board of Education told WYMT’s Jeff Gould that every time someone reports a foul odor, it disappears just moments later, making the search for this mysterious odor at one elementary school a difficult one.

NASA has imposed a ban on spacewalks while experts look for the source of a smoky smell in a space suit worn during a ground test, agency officials said today.

Initial evaluations have not found evidence of burning in the test suit.

The ban could be lifted in time for a pair of critical walks outside the international space station that are scheduled for next week and three outings planned during a December shuttle assembly mission to the orbital outpost.

“Every test so far has been normal,” Mission Control communicator Shannon Lucid told Peggy Whitson, the station’s commander late today. “We hope to have a ‘go’ to use them by tomorrow.”

“That would be great,” said Whitson.

The smoky odor was reported Friday during a test of a space suit assigned for use on a future mission. The test at the Johnson Space Center was halted without injury to any of the test participants, said NASA spokeswoman Brandi Dean.

As a precaution, a ban was imposed until engineers could determine whether there had been burning that could be an indication of problems with all of NASA’s space suits, Dean said.

The restrictions came on the heels of a seven-hour outing by Whitson and Russian cosmonaut Yuri Malenchenko early Friday.

Though testing was still under way today, experts had not found evidence for combustion following examinations of air filters and other materials inside the suit, Dean said.

Additionally, the test suit was re-activated while nitrogen rather than oxygen was circulated internally without signs of malfunction. Oxygen was to be circulated in the garment before the ban was lifted.

Spacewalks by Whitson and astronaut Dan Tani are scheduled for Tuesday and Saturday of next week to prepare the outpost for the arrival of the shuttle Atlantis with a crew of seven U.S. and European astronauts.

Atlantis is scheduled for a Dec. 6 liftoff with the European Space Agency’s Columbus science module. Three spacewalks are planned over the 11-day mission to attach the new lab.

Early Wednesday, Tani and Whitson plan to use the station’s robot arm to reposition the Harmony module that was delivered to the outpost by the crew of the shuttle Discovery late last month.

The repositioning will take place without a spacewalk.

After it has been moved, the new bus-sized module will serve as a gateway between the station’s oldest segments and Columbus and a Japanese science module that will be launched on multiple shuttle missions beginning in mid-February.

During the spacewalk scheduled for next week, Whitson and Tani will connect Harmony to the station’s electrical power grid and cooling network. Earlier this week, Harmony was equipped with the docking mechanism that Atlantis will need to park at the station.

Spartanburg-based Milliken & Company has developed the Active Odor Control odor and air quality management system to neutralize all airborne particles in an automobile’s cabin.

“We’ve spent three years creating Active Odor Control for our Yes Essentials line to address the growing concerns of unpleasant odors and VOCs inside vehicles,” said Sidney Locke, marketing manager, Yes Essentials. “This new innovation provides OEMs with the added assurance of safer air quality levels in cabins.”

A summary of concerns raised in recent health department inspections of area schools, with inspection date.

Manhattan High School (Aug. 15): Several toilets were not in proper working conditions, and most drinking fountains in D wing were not functioning. The girls locker room had one sink without functioning water, a drinking fountain that did not work and no lighting. Records indicated the same problems were noted in last year’s report.

Paper towel or hand dryers were not provided in inspected restrooms. Also, there were at least four rooms where cleaning supplies were not separated from the student population.

Water was disinfected, yet not routinely monitored, backflow and cross contamination issues were found, and the boiler inspection was not current.

Lighting appeared inadequate, pest access and harborage were not restricted. One room was reported to have mouse droppings and holes in walls that needed repair. The inspectors noted that this issue would be rechecked.

Manhattan High East Campus (Aug. 9): Toilets and sinks were not installed and maintained. Adequacy of lighting was questioned. Noted in the report was a complaint in reference to an odor making people sick. The report noted the carpets were cleaned to combat the odor issue.

Blue Valley High School (Aug. 16): No negative indicators.

Riley County High (Aug. 15): The boiler inspection was not current.

Anthony Middle School (Aug. 13): Toilets were not installed and maintained properly; boys and girls toilets were dirty. A sink in the south end of the boys restroom had a drain handle missing. Two of the paper towel dispensers were broken.

The boiler did not have a current inspection.

Eisenhower Middle School (Aug. 10): There was no ground fault plug by the sink in two rooms, and an eye wash station was not hooked up.

Amanda Arnold School (Aug. 15): The boiler inspection was not current and there was a note to check some rust.

Bergman School (Aug. 14): Some sinks and toilets were not installed and maintained properly. Automatic handwashing sensors were not working, a drinking fountain was not working and a toilet was fixed onsite.

Cleaning supplies were not separated from the student population and playground equipment was not safe and in good repair. The hand-hold monkey bars were rusting. Also, one door needed to be weather-stripped. The boiler inspection was not current. There was one broken swing in the kindergarten playground.

Bluemont School (Aug. 8): The report found problems with appropriate water temperature, and sinks and drinking fountains installed and maintained. There was no water for washing in the boys’ restroom on the third floor, and the second floor girls’ restroom had a toilet not flushing.

The building was not handicap accessible, did not have paper towel or hand dryers provided in restrooms, and cleaning supplies were not separated from student population. The boiler inspection was not current. There was a lack of drinking water in a few rooms and cleaning supplies were stored under a sink.

Lee School (Aug. 8): Sinks and toilets were not installed and maintained. There were notes to clean rust from toilet bowls in one of the mobile units. Water that was too hot was an issue in one of the girls’ restrooms.

Cleaning supplies were not separated from the student population. Hazardous chemicals were not stored properly. Playground equipment was not found to be safe and in good repair. The ’s’ hooks were not closed on the swings and the end caps in the teeter totter were off. There was no current boiler inspection. The environmental systems report was positive.

Marlatt School (Aug. 13): Toilets, sinks and drinking fountains were not installed and maintained. Cleaning supplies were not separated from the student population, and playground equipment was not found in safe and good repair. There were notes of rusted chains at the tops of the swings, two chains were broken on the stand and swing, and plastic covering on a ladder was broken and rusting.

ScienceDaily (Nov. 1, 2007) — Some people are oblivious to the odor in the locker room after a game, while others wrinkle their noses at the slightest whiff of sweat. Research by Prof. Doron Lancet, research student Idan Menashe, and colleagues, published in this month’s PLoS Biology, shows that this difference is at least partly genetic.

Our sense of smell often takes a back seat to our other senses, but humans can perceive up to 10,000 different odors. Like mice, which boast a highly developed sense of smell, we have about 1000 different genes for the smell-detecting receptors in our olfactory “retinas.” In humans, however, over half of these genes have become defunct in the last few million years. Some of these genes are “broken” in all people, while others still function in some of the population.

Lancet and his coauthors, from several institutions in Israel and Florida, had their experimental volunteers sniff varying concentrations of compounds that smelled like banana, eucalyptus, spearmint, or sweat. They compared their ability to detect each odor with their patterns of receptor gene loss. The team found that one gene (OR11H7P) appeared to be associated with the capacity of smelling sweat.

Genetic epidemiology analysis reveals a multifaceted mechanism underlying enhanced olfactory sensitivity to the sweaty odor of isovaleric acid in humans.

When participants had two genes with disrupting mutations, they were likely to be impervious to the offending odor, while those that were hypersensitive to the smell had at least one intact gene.

The scientists noted, however, that while having at least one intact OR11H7P gene might determine if you can smell whether your loved one has just come from the gym, this is not the entire story.

Women were generally slightly more sensitive to many smells than men, and some individuals of both sexes were better or worse in across-the-board acuity to all odorants. Furthermore, as is always the case, not all variation was caused by genetic differences; environmental factors were seen to play an important role as well.
