Why do some older people experience a rapid decline in their physical and functional health while some of their peers remain healthy and active? While your genes and overall physical health play a role, new research shows how psychosocial factors can also play an important role. Two studies report on this in the September issue of Psychology and Aging, a journal published by the American Psychological Association (APA).
In the first study, researchers at the University of Texas Medical Branch at Galveston found a link between positive emotions and the onset of frailty in 1,558 initially non-frail older Mexican Americans living in five southwestern states – Texas, California, Arizona, Colorado and New Mexico. This was the first study to examine frailty and the protective role of positive emotions in the largest minority population in the United States.
Study authors Glenn Ostir, Ph.D., Kenneth Ottenbacher, Ph.D., and Kyriakos Markides, Ph.D., followed the participants for seven years and assessed frailty by measuring the participants weight loss, exhaustion, walking speed and grip strength. Positive affect (positive emotions) was measured during the study period by asking the participants how often in the last week "I felt that I was just as good as other people," "I felt hopeful about the future," "I was happy," and "I enjoyed life."

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
