Father's Day this Sunday is a chance to recognize dads for putting up with all manner of nonsense that kids manage to cook up on the way to adulthood.
But a new study by researchers at the University of Arizona shows just how important dad's job as a role model actually is.
The study, "Impact of Fathers on Risky Sexual Behavior in Daughters: A Genetically and Environmentally Controlled Sibling Study," is due to be published in the journal Development and Psychopathology.
MADISON, WI, JUNE 14, 2011 - Tropical maize proves to be a valuable genetic resource, containing genetics not found in USA Corn Belt maize. Most tropical maize varieties respond to the long summer day lengths that occur in U.S. growing regions by flowering late. This delayed flowering response results in poor yields, effectively trapping the useful genes and hindering their incorporation into maize hybrids adapted to the most productive corn growing regions.
PHILADELPHIA — Scientists at Harvard University have created a laboratory model using time-lapse video microscopic technology that allows observation of early stages of ovarian cancer metastasis.
"We were able to observe key molecular mechanisms that are necessary for the force-dependent processes associated with metastasis," said Joan Brugge, Ph.D., professor and chair of cell biology at Harvard University.
BOSTON, Mass. (June 14, 2011) — A team led by Joan Brugge, the Louise Foote Pfeiffer Professor of Cell Biology at Harvard Medical School, recently shed light on how ovarian cancer spreads. In a paper published in the July edition of the journal Cancer Discovery, the newest journal of the American Association for Cancer Research, Brugge and colleagues found that ovarian cancer cells act like bullies, using brute force to plow their way through tissue and colonize additional organs.
Birds with high levels of stress hormones have the highest mating success and offer better parental care to their brood, according to new biology research at Queen's University.
"Having high levels of glucocorticoid or stress hormone is often thought to indicate an individual in poor condition who has a low level of mating success. However, our research indicates that tree swallows with the highest levels of stress hormone have the highest reproductive success," says Frances Bonier (Biology) who investigates the way animals cope with challenges in their environment.
WINSTON-SALEM, N. C., -- June 14, 2011 – Over the past decade, some progress has been made regarding the promise of personalized medicine but scientists are just beginning to consider the impact of gene-diet interactions in different populations in regards to disease prevention and treatment.
A new study from Mount Sinai School of Medicine has found that a cellular signaling pathway governs the differentiation of cells into fat tissue or smooth muscle, which lines the vascular system. Engaging this signaling pathway and its capacity to govern cell differentiation has important implications in preventing obesity and cardiovascular disease. The study is published in the June issue of Developmental Cell.
A new study by researchers at NYU Langone Medical Center has shown that, for the first time, Wnt signaling, already known to control many biological processes, between hair follicles and melanocyte stem cells can dictate hair pigmentation. The study was published in the June 11, 2011 issue of the journal Cell.
Researchers have developed a new method of eliciting and analyzing opinions from a large group of experts and laypeople to aid complex decision-making, adapting online and social media technologies to lower the cost of such activities while expanding the types of people who can be queried.
PHILADELPHIA — Eating a low-carbohydrate, high-protein diet may reduce the risk of cancer and slow the growth of tumors already present, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.
The study was conducted in mice, but the scientists involved agree that the strong biological findings are definitive enough that an effect in humans can be considered.
New Rochelle, NY, June 14, 2011—E. coli bacteria exposed to three common antibiotics were more likely to develop antibiotic resistance following low-level antibiotic exposure than after exposure to high concentrations that would kill the bacteria or inhibit their growth, according to a timely article in Microbial Drug Resistance, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online at www.liebertpub.com/mdr
A team of Australian scientists has discovered a new type of cell in the immune system.
The new cell type, a kind of white blood cell, belongs to a family of T-cells that play a critical role in protection against infectious disease.
Their findings could ultimately lead to the development of novel drugs that strengthen the immune response against particular types of infectious organisms.
It is also potentially significant for many other important diseases including allergies, cancer and coronary artery disease.
Sophia Antipolis, France: Tuesday 14 June : The European Society of Cardiology (ESC) Working Group of Atherosclerosis and Vascular Biology has published a position paper to raise the profile of vulnerable plaques and the need for greater use of therapies to promote plaque stabilisation. The position paper, published online today in Thrombosis and Haemostasis, is also calling for more research into the causes of plaque rupture, and for the development of better diagnostics and treatments.
Tiny fibres used to strengthen everyday products such as bicycle frames and hockey sticks could pose health hazards to those involved in their manufacture.
Certain types of carbon nanotubes – cylindrical molecules about one-thousandth of the width of a human hair – could cause cancer in the lining of the lung, University of Edinburgh researchers have found.
A new study provides support for Darwin's hypothesis that the struggle for existence is stronger between more closely related species than those distantly related. While ecologists generally accept the premise, this new study contains the strongest direct experimental evidence yet to support its validity.
