(Press-News.org) BETHESDA, MD – August 9, 2012 -- As upper level undergraduate genetics instructors plan their syllabi for the fall semester, the Genetics Society of America's GENETICS journal offers a new educational resource, articles called "Primers." These articles are designed to bring cutting-edge scientific research into the classroom by making scientific papers accessible to students.
The principal learning goal of the Primer is to "make research and genetics accessible to a much broader audience, not just researchers, their postdocs and grad students, but also to undergraduates and their instructors," said Elizabeth A. De Stasio, Ph.D., a professor in the department of biology at Lawrence University in Appleton, Wisconsin, and editor of the Primer section in the GENETICS journal.
"With jargon and unfamiliar techniques, the primary research literature can be inaccessible to many students," Dr. De Stasio added. "The Primer article, tied to a research article published in the same issue of GENETICS, will provide guidelines for genetics instructors who want to expose their students to current research."
The August 2012 GENETICS Primer written by Dr. De Stasio is based on the article, "A Network of Genes Antagonistic to the LIN-35 Retinoblastoma Protein of Caenorhabditis elegans," by Stanley R. G. Polley and David S. Fay. The Primer introduces concepts of reverse genetics and RNA interference (RNAi), suppressor screens, synthetic phenotypes and phenocopy. Necessary background, explanations of concepts, as well as suggestions for using the article in the classroom and questions for classroom discussion are included.
"The intent is for the research article and the Primer to be used together in the context of a genetics classroom. We will be highlighting articles that teach and reinforce genetic principles and approaches, while concentrating on current, rather than classic discoveries," Dr. De Stasio noted. "Focusing the Primers on contemporary scientific literature will engage students in the learning process and guide them toward the process of scientific discovery." Dr. De Stasio expects the Journal to publish six Primer articles each year, about one in every other issue of GENETICS.
"Providing valuable educational resources like this that enhance the quality of genetics education, teaching and learning is one of our missions." said Mark Johnston, Editor-in-Chief of GENETICS. "Engaging students in the process of critically analyzing primary research is a vital part of research training."

HIGH LEVELS of iron could raise the risk of bowel cancer by switching on a key pathway in people with faults in a critical anti-cancer gene, according to a study published in Cell Reports* today (Thursday).
Cancer Research UK scientists, based at the University of Birmingham and the Beatson Institute for Cancer Research in Glasgow, found bowel cancers were two to three times more likely to develop in mice with a faulty APC gene that were fed high amounts of iron compared to mice who still had a working APC gene.
In contrast, mice with a faulty APC gene fed a diet low ...
EAST LANSING, Mich. — Most of America's urban cores were designed for walking but offer little in the way of supermarkets, healthy restaurants and other amenities for residents to walk to, according to a study led by a Michigan State University scholar.
The study is one of the first to show that poor residents living in declining urban neighborhoods want healthy food choices – evidenced by their willingness to travel long distances to find them. Past research has generally assumed that poor people will shop at whatever store is closest.
But compared with suburban residents, ...
Dark matter was first proposed by the Swiss astronomer Fritz Zwicky in the 1930s. He found that clusters of galaxies were filled with a mysterious dark matter that kept them from flying apart. At nearly the same time, Jan Oort in the Netherlands discovered that the density of matter near the Sun was nearly twice what could be explained by the presence of stars and gas alone. In the intervening decades, astronomers developed a theory of dark matter and structure formation that explains the properties of clusters and galaxies in the Universe, but the amount of dark matter ...
SHREWSBURY, MA – A new study published in Nutrition Journal shows that people can lose weight while consuming typical amounts of sugar or high fructose corn syrup (HFCS) if their overall caloric intake is reduced.
"Our research debunks the vilification of high fructose corn syrup in the diet," said James M. Rippe, M.D., one of the study authors. "The results show that equally reduced-calorie diets caused similar weight loss regardless of the type or amount of added sugars. This lends further support to findings by our research group and others that table sugar and HFCS ...
Eighty-nine million Americans were without health insurance for at least one month during the period from 2004 to 2007, and 23 million lost coverage more than once during that time, according to researchers at Penn State and Harvard University.
"These findings call attention to the continuing instability and insecurity of health insurance in our country," said Pamela Farley Short, professor of health policy and administration, Penn State. "With more than a third of all Americans under age 65 being uninsured at some point in a four-year period, it's easy to see that the ...
Language use in books mirrors trends in gender equality over the generations in the US, according to a new study by Jean Twenge, from San Diego State University, and colleagues. Their work explores how the language in the full text of more than one million books reflects cultural change in U.S. women's status. The study is published online in Springer's journal Sex Roles.
Twenge and colleagues, W. Keith Campbell and Brittany Gentile of the University of Georgia, examined whether the use of gendered pronouns such as 'he' and 'she' mirrored women's status between 1900-2008, ...
CHAMPAIGN, Ill. — Various misconceptions surrounding the continued viability of Medicare can be debunked or discredited, making it more important than ever for voters and policymakers to fully understand the program's existing contours and limitations, according to a paper published by a University of Illinois expert on retirement benefits.
Law professor Richard L. Kaplan says Medicare has become one of the most controversial federal programs for numerous reasons, but misinformation has played a key role in fostering criticism of it.
"Medicare is an important and complicated ...
According to theoretical physicists João da Cruz and Pedro Lind from Lisbon University, Portugal, imposing minimum capital levels for banks may not prevent the insolvency of a minority of banks from triggering a widespread banking system collapse. In a study recently published in EPJ B1, the researchers explain why this measure could instead lead to larger crises.
The authors created a model of banks' behaviour to assess the conditions needed to avoid "avalanches" of insolvent banks. Their model is based on a physical system of particles representing how banks are attracted ...
Los Angeles, CA (August 09, 2012) Poorly-performing medical implants have hit the headlines recently, and the trend looks set to continue: the September issue of the Journal of Hand Surgery (JHS) homes in on the unacceptable performance of hand implants for osteoarthritis patients. Citing several recent studies, the editorial asks why these implants – which perform worse that certain hip replacement implants now deemed unacceptable – are still widely used. JHS is an online and print, orthopedic surgery journal published by SAGE.
The issue reports on a number of thumb ...
