In the spectrum of light, there hertz and X-ray wavelengths. Vardeny called it a "teenager," because are many different levels—the mait fits into the middle of the spec- jority cannot be seen by the naked trum and knowledge of its capacity eye. Natalie Hale The Daily Utah Chronicle T h e y t h e n s e t When a crystal is X-rayed, the image produced has a structured and square-like pattern, known as periodic. In the '8os, scientist Dan Shechtman discovered an anomaly—not all crystals comply with this pattern. He coined them "quasicrystals" because they have distinct patterns. But if interrupted, the entire shape of the crystal is destroyed. Until this study, such complete and rapid transmission has only been able to be achieved when crystal patterns were used. Nahata and Vardeny said most technology operates with gigahertz signals, and the development of terahertz will change thespeed at which today's electronic devices function. "This is an unexploredfield,and (the research) is a starting point to make devices for the terahertz range," Nahata said. Nahata said he estimates that in the next decade wireless communication will begin making the shift to using terahertz because of its speed. "People want to be able to transfer data at a faster rate; there is a non-stop need to send information at faster rates," Nahata said . With development of technology using teraherta wavelengths, faster transmission of data is just around the comer, Nahata said. The research Nahata and Vardeny conducted was published in the March edition of Nature magazine, and can be accessed online at www.nature.com/nature/journal/ v446/nyi3s/fuU/natureo562o.html. n.hale@ chronicle.utah.edu NEW MAJOR AND MINOR OFFERED AT THE U LENNIE MAHLZR/TheDJIIV Uteh CknwtJe Yellowcard lead singer Ryan Key sings at last year's Grand Kerfuffle. The Presenter's Office will be charging $5 for this year's April 18 event. KERFUFFLE BRINGS MOS DEF AND A NEW FEE rently has $80,000 in its budget, but money will be made up through ticket revenue. The office expects between $12,000 and $20,000 in extra continued from Page I more than $270,000 on the show. Hansen told The Daily Utah Chronicle in August that without a reserve to fall back on, students would have to pay entry fees to music festivals this year. "We decided to charge to be able to bring- bigger named artists working within our budget," Hansen said. Although Hansen was originally unsure of which concerts students would be charged for, he said the Presenter's Office decided to have students pay for the Redfest concert festival in September so they could have a "good size Kerfuffle." He called the charge an "appropriate use of funds." By charging students for these events, Hansen said he hopes to give out about 1,000 free student tickets to attend the debate between Salt Lake City Mayor Rocky Anderson and conservative pundit Sean Hannity. The debate, sponsored by ASUU, will be held May 4 and the venue has yet to be decided. Although the total cost ASUU will spend to produce this year's Kerfuffle has not been determined, Hansen said he estimates the concert will cost about $80,000. The Presenter's Office cur- revenue. About $40,000 has already been spent on the Kerfuffle, with $35,060 going toward artist fees. While the Presenter's Office went over its personal budget last year, current leaders said ASUU as a whole was not affected by changes made in its budget. "We had a certain budget we were trying to meet, but we knew very well that we could use other funding to pay for the event," said former Student Body President Ali Hasnain. Current Student Body President Jake Kirkham said his administration has adamantly encouraged everyone on staff to stay within its budget. Kirkham said he does not believe an entrance fee will have a negative effect on concert attendance. "By charging for events, it just allows us to do more programming," Kirkham said. "Students are still getting a great deal...Mos Def is a very popular artist and $5 is not bad at all." Hansen said the Presenter's Office was looking for a hip-hop concert this year and students expressed interest in the possibility of Mos Def coming to the U. The bands Hezekiah and AKA That Subliminal Kid will open the concert. r.mcconkie@ chronicle.utah.edu of languages and literature agreed that students would see the world differently after completing a degree in comparative literacy and cultural studies.

Over half of ttiosa studenis suffer academically as a result. Are your grades suffering due to sleep deprivation? If so, read the following sleep tip. Tip #4 Finish eating at least 2-3 hours before your regular bedtime. Eating or drinking too much may make you less comfortable when settling down for bed. It is best to avoid a heavy meal too close to bedtime. Also, spicy foods may cause heartburn, which leads to difficulty falling asleep and discomfort during the night.
