Social media-based movements like #BlackLivesMatter and #SayHerName have taken off over the past decade as a response to highly scrutinized police shootings of African American people. Recordings from body cameras or bystanders are frequently posted online and shared by activists and others as a way to press for police accountability.

But those videos may also have deleterious effects on the mental health of young members of the same racial communities as the victims in those shootings, suggests a new study published today in the Journal of Adolescent Health.

(Glasgow, 8 June, 2019) A new blood test could become clinical practice within five years, reducing the need for a liver biopsy in the management of paediatric Non-Alcoholic Fatty Liver Disease (NAFLD), as a major new international paediatric liver registry collaboration yields early results [1].

Bochum-based researchers from the Cluster of Excellence Ruhr Explores Solvation (Resolv), together with cooperation partners from Nijmegen, have investigated how acids interact with water molecules at extremely low temperatures. Using spectroscopic analyses and computer simulations, they investigated the question of whether hydrochloric acid (HCl) does or does not release its proton in conditions like those found in interstellar space. The answer was neither yes nor no, but instead depended on the order in which the team brought the water and hydrochloric acid molecules together.

BUFFALO, N.Y. - A University at Buffalo-led research team has used public narratives, an increasingly popular form of person-centered advocacy offering a forum for sharing previously untold stories, to study the undue stress experienced by women in relation to abortion.

Storytelling is a universal characteristic of humanity, present throughout history and manifest in every culture. Stories told over time on similar themes present rich patterns that enhance understanding, encourage empathy and provide insights into a lived experience that can be unfamiliar to its audience.

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.

Clinicians often feel that they have a role in preventing firearm injury. But few talk with patients about the risk of firearms and safe firearm practices during office visits.

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.
