into the air, stripping electrons off atoms, and adding them on to others. This intensifies the atoms in the air. The negatively charged needle intensifies the oxygen in the air. thus making the animal active. The positively charged needle intensifies the carbon dioxide in the air, thus making the mouse sluggish. Twelve experiments were performed. Two of these were failures due to the mouse's sleeping con- dition. The following conclusions were reached: Negative ions definitely increase appetite, sleeplessness, quick response to outside stimulus, and activity. Positive ions definitely decrease appetite, sleeplessness, rapidity of response to outside stimulus, and activity. These principles can be used to promote relief from depression or hysteria in mental illness, to stimulate astro- nauts for important maneuvers, or anything else requiring increased activity or lethargy.

By controlling light, tem- perature, and food, I was able to observe these effects on hydra. These were determined over a period of about five months. My conclusions are as follows: Healthy, well fed hydra iwill reproduce by budding after five or six days. Excess food in a small volume will cause hydra to die. Light is a lfundamental influence in the cycle of life. It is a natural consequence that hydra will go to the light to catch food, because it is most abundant there. When you have reduced oxygen in a tank, this alone does not stimulate formation of reproductive organs. Also low temperatures alone' will not form reproductive organs. When the environment of de- creased oxygen and low temperatures are present, male and female reproductive organs are produced. Hydra will survive in an aquarium. Sick hydra have short, stubby tentacles. Tem- peratures close to freezing will kill hydra. A temperature between 550 - 66 CFJ is adequate for living conditions. TERESA PONIECKI U Ol Madonna High School Chicago, lll. Sponsor: Sister Mary Alvernia In recent years the process of protein synthesis has become of great interest to scientists. If the entire process of protein synthesis can be completely understood, than we might make protein outside the living body. The most puz- zling aspect was decoding the nucleotide sequence of the transfer RNA's which have a major part in protein synthesis. At the present alanine transfer RNA has been decoded. My project dealt with this material. I grew dry yeast in a beef broth solution and fresh yeast in a sugar solution. Then, by the process of chromato- graphy, I tried to find traces of alanine transfer R N A. My results were up to my expectations. Now there is left the problem of decoding the nucleotide sequences of other amino acid transfer R N A's. Personality Change 'From Ions eEo'ReE sTuTz lap Stanley Field Jr. High Northbrook, lil. Because of the chemical change on a living animal's body from ions, personality control through ions is possible. This is due to the intensified form of oxygen and carbon dioxide formed in the air. It is formed by the electrostatic charge escaping from the needle into the air. When the needles in the mice cages become strongly charged, the charge escapes
