SAN ANTONIO - Preliminary results from a new study suggest that sleep disturbances are associated with mental health problems among survivors of a natural disaster even two years after the event.

Sudden hearing loss can be experienced in highly stressful situations, usually lasting a short time. Researchers at São Paulo State University (UNESP) in Brazil, collaborating with colleagues at Oxford Brookes University in the United Kingdom, have reported a discovery that contributes to a deeper understanding of this phenomenon.

New research provides insight into the structure of silicon nanocrystals, a substance that promises to provide efficient lithium ion batteries that power your phone to medical imaging on the nanoscale.

The research was conducted by a team of University of Alberta chemists, lead by two PhD students in the Department of Chemistry, Alyx Thiessen and Michelle Ha.

Many pesticides that have been banned or are being phased out in the EU, Brazil and China, are still widely used in the USA, according to a study published in the open access journal Environmental Health.

Analyzing the data on 10,077 citizen complaints lodged against the Chicago Police Department between 2011 and 2014, a pair of New York University researchers has found that just 2 percent of allegations made by black Chicagoans resulted in a recommendation for sanction against an officer, compared to 20 percent for white complainants and 7 percent for Latino complainants.

Adversity early in life tends to affect a child's executive function skills -- their ability to focus, for example, or organize tasks.

Experiences such as poverty, residential instability, or parental divorce or substance abuse, also can lead to changes in a child's brain chemistry, muting the effects of stress hormones. These hormones rise to help us face challenges, stress or to simply "get up and go."

Science professors go through years of training to learn about their field, yet they often don't receive any formal education in how to teach students about it. A new study takes a decade-long look at one way that science departments in the California State University (CSU) system are trying to amend that by bringing faculty with educational expertise into the fold.

CLEVELAND, Ohio (June 5, 2019)--Physical fitness is associated with a number of key health outcomes, including heart disease, cognition, mortality, and an overall feeling of well-being. A new study from Singapore now links physical performance with mental health and emotions, suggesting that weak upper and lower body fitness can cause more serious depression and anxiety in midlife women. Results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

There is concern about the misuse of the sedative anti-anxiety medication alprazolam (Xanax®) because of the "high" it can create. A new British Journal of Clinical Pharmacology study found that non-medical use of alprazolam in the United Kingdom is a significant issue, and it appears to be more prevalent in younger adults.

Research at the University of York has shown that women are underrepresented in research into links between cannabis and psychosis, which could limit understanding of the impact of the drug.

In a review of scientific literature over a number of years, Ian Hamilton from the University of York's Department of Health Sciences, found that the majority of research reflects the experience of male cannabis users, with very limited information on how women react to the drug.

LOWELL, Mass. - The risk of heart disease and death increases with the number of eggs an individual consumes, according to a UMass Lowell nutrition expert who has studied the issue.

Ask just about any parent whether napping has benefits and you'll likely hear a resounding "yes," particularly for the child's mood, energy levels, and school performance. New research from the University of Pennsylvania and the University of California, Irvine, published in the journal SLEEP backs up that parental insight.

Children exposed to paternal tobacco smoking before birth are more likely to develop asthma - and associated changes to immune genes predict the level of risk.

These are the findings of a new study of Taiwanese families, whose lifestyle and genetic make-up were analyzed to determine how fathers' tobacco smoking during pregnancy relates to asthma risk in their children.

An international study involving researchers from UBC Okanagan has shown that MDMA, also known as ecstasy, may be a valuable tool for treating post-traumatic stress disorder (PTSD).

Published recently in Psychopharmacology, the study demonstrated substantial improvements in individuals who had not responded to prior treatments, explains UBCO Associate Professor of psychology Zach Walsh. This is also, he adds, the most comprehensive evaluation of the safety and effectiveness of MDMA-assisted psychotherapy for PTSD.
