Along the way, let us stop to recognize some of our young people for their accomplishments. Friday night at the Junior Senior High Band Concert, ten new members of the Westbrook Walnut Grove High School were inducted into the National Honor Society. To be inducted, students must demonstrate scholarship, leadership, service and character. These four pil- lars of the NHS are evaluated based on student work in school and community. Though NHS selection is certainly a nice honor, it is also something that one grows into over time. The four pillars mark a high standard to use to measure one's growth and accomplishments. Matt Otto was announced as the WWG Excel Award Winner for excellence in academics and athletics for juniors. Seniors Hailey Osland and Andrew Merrick were honored as the WWG Triple A Award Winners. Both awards are sponsored by the Minnesota State High School League. ,i:, ~- . ! ~:t! '! ......... ? ' ; ..... '.I. 66 complex polyextremophiles tion.

Given that they also move like a lumbering bear, tardigrades have eamed the nickname water bear. Tardigrades typically live in marine, fresh water, or semiaquatic environments, but you can also find them in the mosses and lichens found in forested areas. As long as there is some water around, they can thrive. They feed on the fluids found in plant and animal cells. Their mouth is able to pierce the cell walls so that they can then suck out and ingest the inner parts of the cell. Tardigrades can survive being completely desiccated for nearly I 0 years as well as exposure to high levels of chemical toxins. They can survive extreme heat (150 C) for a few minutes and extreme cold (-200 C) for a few day. When exposed to extreme cold their body com- position changes from 85% water to only 3% which keeps their body from being damaged by ice crystal for- mation. The can survive extreme pressures far greater than that found at the Mariana trench. In 2007, tardigrades were sent into space on the R_u at el lit e Foton-M3 for ten days. Even after being exposed, to the research. You're probably wonder- ing just how these creatures could be so resilient. They rely on cryptobiosis--a state of suspended animation that they can enter in response to adverse environmental con- ditions where all metabolic processes stop. Their bodies dehydrate into a dense, mum- miffed disc called a tun. They can remain in this state indef- initely until their environ- ment becomes hospitable once again. When this hap- pens, the tun plumps back up and the tardigrade return to its previous metabolic state. 1) True or false: Cryptobiosis is a form of suspended animation. 2) True or false: Tardigrades can survive both extreme cold and heat equal- ly well. 3) During cryptobiosis, all ??? functions stop. 4) Tardigrades need ??? to thrive, a) sunlight b) carbon dioxide c) water d) their wits 5) When a tardigrade under- goes cryptobiosis, it's dried body is called a ???. a) tan b)ten c)tin d)ton e) tun Answers on page 2 Copyright (C) 2013 Wee y Science QIii -A-lt-"rlglRs reserved. tP'lD Last week Bill Richards worked with the junior high musical "Willy Wonka Jr." It will be presented this week at the high school auditorium.
