Scientists discover that chromosomal rearrangements can be advantageous
Date: Aug-27-2013In a pioneer study published in the latest issue of the scientific journal Nature Communications*, a research team at the Instituto Gulbenkian de Ciencia (IGC; Portugal), led by Miguel Godinho Ferreira in collaboration with Isabel Gordo, show for the first time that chromosomes rearrangements (such as inversions or translocations) can provide advantages to the cells that harbor them depending on the environment they are exposed...
Higher intake of fruits and vegetables may reduce the risk of bladder cancer in women
Date: Aug-27-2013University of Hawaii Cancer Center Researcher Song-Yi Park, PhD, along with her colleagues, recently discovered that a greater consumption of fruits and vegetables may lower the risk of invasive bladder cancer in women. The investigation was conducted as part of the Multiethnic Cohort (MEC) Study, established in 1993 to assess the relationships among dietary, lifestyle, genetic factors, and cancer risk. Park and her fellow researcher's analyzed data collected from 185,885 older adults over a period of 12...
Errors and distractibility increased by music preferences of teen drivers
Date: Aug-27-2013Teens listening to their preferred music while driving commit a greater number of errors and miscalculations, according to a new study from Ben-Gurion University of the Negev researchers. It will be published in the October issue of Accident Analysis and Prevention. Male novice drivers in particular make more frequent and serious mistakes listening to their preferred music than their less aggressive, female counterparts, the researchers noted. The BGU study evaluated 85 young novice drivers accompanied by a researcher/driving instructor...
Insight into human development and disease promised by unprecedented control of genome editing in flies
Date: Aug-27-2013In an era of widespread genetic sequencing, the ability to edit and alter an organism's DNA is a powerful way to explore the information within and how it guides biological function. A paper from the University of Wisconsin-Madison in the August issue of the journal GENETICS takes genome editing to a new level in fruit flies, demonstrating a remarkable level of fine control and, importantly, the transmission of those engineered genetic changes across generations...
Blood test used to find recurrence of ovarian cancer uncovers invasive, high-grade disease at curable stage
Date: Aug-27-2013Evaluating its change over time, CA-125, the protein long-recognized for predicting ovarian cancer recurrence, now shows promise as a screening tool for early-stage disease, according to researchers at The University of Texas MD Anderson Cancer Center. The updated findings are published in Cancer; preliminary data were first presented at the 2010 American Society of Clinical Oncology (ASCO) annual meeting...
A happier retirement ensured by better management of free time
Date: Aug-27-2013Retirees should be masters of their own destiny, and actively manage and plan their free time to ensure a happy and fulfilling retirement. This is the advice of Wei-Ching Wang of the I-Shou University in Taiwan, leader of a study published in Springer's journal Applied Research in Quality of Life. The study found that the effective management of free time has a far greater impact on a retiree's quality of life than the amount of time the person actually has available for leisure activities...
Portable device attaches to smartphone and provides instant results for common kidney tests
Date: Aug-27-2013A lightweight and field-portable device invented at UCLA that conducts kidney tests and transmits data through a smartphone attachment may significantly reduce the need for frequent office visits by people with diabetes and others with chronic kidney ailments. The smartphone-based device was developed in the research lab of Aydogan Ozcan, a professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, and associate director of the California NanoSystems Institute...
Youngest preemies at high risk of neurodevelopmental problems later on
Date: Aug-27-2013Very premature babies are at a significantly high risk of having moderate-to-severe and severe neurodevelopmental impairments later on in childhood, researchers from The Ottawa Hospital, Ontario, Canada, reported in Jama Pediatrics. Gregory P. Moore, M.D., F.R.C.P.C., and colleagues carried out a meta-analysis of previously reported studies. They wanted to determine the rate of moderate-to-severe to severe neurodevelopmental impairment by gestational age in very early premature babies who were followed up four and eight years later...
Genomic differences discovered in types of cervical cancer
Date: Aug-27-2013A new study has revealed marked differences in the genomic terrain of the two most common types of cervical cancer, suggesting that patients might benefit from therapies geared to each type's molecular idiosyncrasies. The study, published in the online version of the journal Cancer by researchers at Dana-Farber Cancer Institute and Brigham and Women's Hospital (BWH), is the first to compare the spectrum of cancer-related gene mutations in the two main subtypes of cervical cancer - adenocarcinoma and squamous cell carcinoma...
How SARS virus hijacks host cells
Date: Aug-27-2013UC Irvine infectious disease researchers have uncovered components of the SARS coronavirus - which triggered a major outbreak of severe acute respiratory syndrome in 2002-03 - that allow it to take over host cells in order to replicate. This insight is critical for a full understanding of any outbreaks caused by such viruses and may prove beneficial in the development of therapies not only for human coronavirus infections but for other pathogenic illnesses as well. Study results appear online in the July/August issue of mBio...
