It’s Not Always the DNA

Posted: Published on November 13th, 2014

Contact Information Available for logged-in reporters only Newswise Damage to DNA is an issue for all cells, particularly in cancer, where the mechanisms that repair damage typically fail. The same agents that damage DNA also damage its sister molecule messenger RNA (mRNA), which ferries transcripts of the genes to the tens of thousands of ribosomes in each cell. But little attention has been paid to this damage. Everybody thought, Why care about the messenger RNA? These molecules have high turnover rates and are quickly degraded, so what does it matter if one is damaged? said Hani Zaher, PhD, assistant professor of biology in Arts & Sciences at Washington University in St. Louis. In organisms like E. coli or yeast, thats probably true, Zaher said. You dont have to worry about mRNA because it turns over really fast. But in neurons you cant use that argument because an mRNA can persist, in some cases for days. And if that mRNA is really damaged it can become a big problem. There may be cases where messenger RNA is just as important as DNA, said Carrie Simms, PhD, a postdoctoral associate in Zahers lab. Clearly oxidative damage to RNA is somehow involved in … Continue reading

Chemistry of the Cocktail

Posted: Published on November 13th, 2014

RENO, NV - Chemistry of the Cocktail has become the Discovery Museum's biggest fundraiser. The highlight of this event is in the name, which makes you wonder, how do science and spirits relate to one another? Patrick Turner, Director of Marketing and Communications for the museum, says the two go hand in hand. "At its base it's chemistry. It's the mixing of different acids and bases that create the flavors and different concoctions," he says. The annual event aims to teach people the science behind the drink-making process and how to take in all of the flavors you are tasting. Of course, most of us don't really think of science when we're making a drink. Like cooking, we're just following a recipe, but according to Lo Martinez, creating the perfect cocktail takes some finesse. "You can throw a bunch of stuff together, but it's probably going to taste bad. So, there is a formula in everything that we do," she says. Martinez is the vice-president of the Reno chapter for the U.S. Bartenders Guild. This year will be the first time that the Discovery Museum has recruited help from the USBG to give people in the community a lesson in … Continue reading

Flood in Old Chemistry building, maintenance questioned

Posted: Published on November 13th, 2014

By Benny Sisson and Chastity Laskey | Published 10 hours ago | Updated 9 hours ago A flood in the Old Chemistry building Wednesday morning, which was responsible for a complete network shutdown, raised concerns about the UAs maintenance of buildings. The Old Chemistry buildings network connection went down Wednesday morning due to a flood in the south side of the buildings basement, which contained wiring systems to control the connection. Although causes of the flooding have not been officially pinpointed or confirmed, the building staff was not surprised by the incident.Michael Morris, IT manager for the department of chemistry and biochemistry, said someone might have turned the valve because the steam pipes had not been touched in years. Someone enabled something that filled up the room with steam, which damaged all of our networking equipment that is also housed in this room, Morris said. Faculty noticed the network was down and called laboratory manager Scott Dreisbach, who noted that theres also networking equipment in the basement.University Information Technology Services responded quickly and were there in minutes, according to building staff. They had the system back online by Wednesday afternoon. In this case, it is a major shut down of … Continue reading

Chemistry is constant for The Constantines

Posted: Published on November 13th, 2014

Toronto indie band plays in St. Johns tonight as reunion tour comes to a close Years apart couldnt alter the musical chemistry of The Constantines. The Toronto-based indie band stopped gigging in 2010 after more than a decade of making records together, going their own ways to work on separate projects. TheConstantines are (from left) Bryan Webb, SteveLambke, Doug MacGregor, Will Kidman and Dallas Wehrle. They play tonight at The Rock House inSt. Johns. Submitted photo At the time, I dont know if we knew whether it was a breakup or a slowing down, said band member Steve Lambke. We kind of got to the point where it was time to start writing another (record), and I dont think any of us really felt emotionally up to it, or maybe creatively up to it, at that time. So we just needed to take a step back and try other things. It seems time apart has only made them better together. When the former bandmates decided to join forces for another tour this year, it all came back quickly, said Lambke, who brings his vocals, guitar and keyboard back into the mix. It was cool, and it was surprising. And since … Continue reading

NABT recognizes chemistry teacher with Genetics Education Award

Posted: Published on November 13th, 2014

PUBLIC RELEASE DATE: 13-Nov-2014 Contact: Nalini Padmanabhan press@ashg.org 301-634-7346 American Society of Human Genetics @GeneticsSociety BETHESDA, MD - The National Association of Biology Teachers (NABT) has named Robert R. Gotwals, Jr., M.S., chemistry and research instructor at the North Carolina School of Science and Mathematics (NCSSM) in Durham, the 2014 recipient of its Genetics Education Award. This annual award recognizes innovative, student-centered classroom instruction to promote the understanding of genetics and its impact on inheritance, health, and biological research. Sponsored by the American Society of Human Genetics (ASHG) and the Genetics Society of America (GSA), the award will be presented to Mr. Gotwals on Saturday, November 15, during NABT's 2014 Professional Development Conference in Cleveland, Ohio. In addition to a recognition plaque and a year of complimentary membership to NABT, GSA, and ASHG, Mr. Gotwals will receive a $1000 cash prize. Mr. Gotwals, who holds an undergraduate degree in chemistry and master's degrees in science education and education for the hearing-impaired, has developed resources related to research and computational chemistry for both students and teachers. In particular, he worked with the Jackson Laboratory in Bar Harbor, Maine, to create and implement a program for high school students to conduct genetics … Continue reading

Carus conducts chemistry shows

Posted: Published on November 13th, 2014

Carus Corporations annual National Chemistry Week tour recently hit 16 schools, bringing science demonstrations to more than 2,000 students. I want them to get more experiments and come back again, said Austin Robinson, an eighth-grader at Northbrook Middle School in Mendota. Im thinking I might want to do something with science now. The demonstrations featured chemical reactions that foamed, fizzed, steamed, changed color and produced light. More than 40 Carus volunteers visited middle schools in Ottawa, Streator, Utica, LaMoille, La Salle, Lostant, Mendota, Oglesby, Peru, Sheridan, Spring Valley and Tonica during National Chemistry Week, which ran Oct. 19-25. The week was established by the American Chemical Society. Carus extended the "week" to more than three weeks, in order to accommodate as many schools as possible. For the first time, Carus also is going to bring a chemistry demonstration later this month to Horizon House in Peru. Our goal is to show kids that learning can be fun. We want them to show up to science class energized after our visit, knowing that chemistry makes a huge difference in our world, and that local career opportunities in chemistry are waiting for them, said Sean Davenport, Carus technology development manager. Kegan Pakula, … Continue reading
