TORONTO, ON - A new study from researchers at the University of Toronto found that 63% of Canadians with migraine headaches are able to flourish, despite the painful condition.

AMES, Iowa -- A new study of small Iowa towns found that vulnerable populations within those communities face significantly more public health risks than statewide averages.

The study, published this week in PLOS ONE, a peer-reviewed open access journal, was led by Benjamin Shirtcliff, associate professor of landscape architecture at Iowa State University.

Middle school, a time when children's brains are undergoing significant development, is often also a time of new challenges in navigating the social world. Recent research from the Center for BrainHealth at UT Dallas demonstrates the power of combining a virtual platform with live coaching to help students enhance their social skills and confidence in a low-risk environment.

Beware of those snack attacks. A new study in Appetite has confirmed the small luxuries, from sweets and chocolate to salty treats, have helped to lift our spirits - and kilojoule intake - during COVID-19 lockdowns.

Researchers in England and Australia have gathered evidence about similar experiences in the UK and Victoria, Australia to warn about the effect of extended pandemic lockdowns on our eating behaviours.

A beetle bores a tree trunk to build a gallery in the wood in order to protect its lay. As it digs the tunnel, it spreads ambrosia fungal spores that will feed the larvae. When these bore another tree, the adult beetles will be the transmission vectors of the fungal spores in another habitat. This mutualism among insects and ambrosia fungi could be more than 100 years old --more than what was thought to date-- according to an article published in the journal Biological Reviews.

COLUMBIA, Mo. - Throughout her 20-year career as a nurse practitioner, Jennifer Hulett noticed survivors of breast cancer would often express gratitude for being alive and mention God or a divine acknowledgement that had improved their health and well-being.

Now an assistant professor at the University of Missouri Sinclair School of Nursing, Hulett is researching the benefits of spirituality on improving immune health and reducing stress, as well as the chances of cancer reoccurrence, among breast cancer survivors.

Chronic psychosocial stress--which involves a pathway called the hypothalamic-pituitary-adrenal axis (HPA axis)--may contribute to the development of Alzheimer's disease. A new review published in Biological Reviews describes how environmental and genetic factors can impact individuals' HPA axis, and ultimately their risk of Alzheimer's disease.

The authors of new research say supporting children and young people's mental health is as important as supporting their academic progress, and that particular attention should be paid to the fact that some young people have struggled more than others.

Washington, DC, June 21, 2021 - Depression in youth, between the ages of 10 and 24 years, is both a leading cause of stress and a possible risk factor for future diseases and impairment.

New findings published this week in Physical Review Letters, Measurement of the Iron Spectrum in Cosmic Rays from 10??GeV/n to 2.0??TeV/n with the Calorimetric Electron Telescope on the International Space Station, suggest that cosmic ray nuclei of hydrogen, carbon and oxygen travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently.

Researchers have shown why people with mental health disorders, including anorexia and panic disorders, experience physical signals differently.

The researchers, from the University of Cambridge, found that the part of the brain which interprets physical signals from the body behaves differently in people with a range of mental health disorders, suggesting that it could be a target for future treatments.

Post-traumatic stress disorder (PTSD) and migraine often co-occur, but researchers knew relatively little about how or why this happens. A new study in Frontiers in Neuroscience is the first to investigate if the conditions have a common genetic basis. By studying identical twins, where one twin in each pair lives with PTSD or migraines and the other twin does not, the researchers found common genes that may play a role in both conditions.

Washington, D.C. - June 20, 2021 - Increased screen time among young adults during the COVID-19 pandemic correlated with a rise in pandemic-related distress, according to research led by investigators at the Saint James School of Medicine on the Caribbean island nation, Saint Vincent. The increase in time spent viewing entertainment on a screen both prior to and during the pandemic was associated with a boost in anxiety scores. Students scored higher than non-students in pandemic-related distress.

After graduating or leaving college, many students face a difficult choice: Try to pay off their student loans as fast as possible to save on interest, or enroll in an income-based repayment plan, which offers affordable payments based on their income and forgives any balance remaining after 20 or 25 years.

Study Highlights

New research reveals how key proteins interact to regulate the body's response to stress

Targeting these proteins may help treat or prevent stress-related psychiatric disorders

The biological mechanisms behind stress-related psychiatric conditions, including major depressive disorder and post-traumatic stress disorder (PTSD), are poorly understood.
