A protein found in healing muscles of younger mice helps older animals bounce back from injury.
Researchers at the University of Queensland have discovered that the thickness of the brain's outer layer influences how individual neurons process information.
Chronic obstructive pulmonary disease (COPD) is much more common among never smoking older women who are morbidly obese (having a body mass index of 40 or higher) than among their female peers in the normal weight range (13.4 percent vs 3.5 percent, respectively). Morbidly obese older men who have never smoked also had a much higher prevalence of COPD than never-smoking men who were normal weight (7.6 percent vs 2.5 percent).
Economic conditions can shape the decisions that adults make about their families, such as whether and when to have children. A recent Journal of Marriage & Family analysis of US women aged 20 to 44 years found that higher unemployment rates were associated with a lower likelihood of unintended pregnancy.
In a randomized controlled trial of 134 mildly stressed, middle-aged to older adults, participants who were assigned to a six-week mindfulness-meditation training program experienced significantly reduced negative affect variability -- which refers to subjective distress and includes a range of mood states such as worry, anxiety, anger, self-criticism, and life dissatisfaction -- compared with participants assigned to a waitlist control.
Men who use androgenic anabolic steroids -- such as testosterone -- may face a higher risk of early death and of experiencing more hospital admissions, according to a new Journal of Internal Medicine study.
Researchers at the University of Bristol have made stronger links between psychotic experiences and different types of trauma in childhood.
Mount Sinai study discovers that imagining threats can weaken reactions to them by suppressing perceptual and learning neural mechanisms.
Researchers at the Icahn School of Medicine at Mount Sinai and the University of Colorado, Boulder, have found that imagining a sound can be just as effective in breaking an association between that sound and a negative experience as hearing the sound in real life. The findings, publishing Nov. 21 in the journal Neuron, help to explain why imagination, already widely used as a therapy tool, can help with anxiety disorders.
Findings from a new study suggest that people who are experiencing a romantic crush may be more drawn to seeking variety in their purchases as a way to restore a sense of control.
