A new Physiological Reports study reveals that evening use of light-emitting tablets can induce delays in desired bedtimes, suppress secretion of melatonin (the hormone that regulates sleep and wakefulness), and impair next-morning alertness. Nine healthy adults participated in a randomized and counterbalanced study comparing 5 consecutive evenings of unrestricted use of light-emitting tablet computers versus

In a new study, researchers have developed updated guidelines for classifying a serious form of skin cancer called invasive melanoma. The American Joint Committee on Cancer, an organization that provides information on “cancer staging,” or the severity of individual cases of cancer, recently updated its guidelines for melanoma. The researchers found that when pathologists used

Among couples being treated for infertility, depression in the male partner was linked to lower pregnancy chances, while depression in the female partner was not found to influence the rate of live birth, according to a study funded by the National Institutes of Health. The study, which appears in Fertility and Sterility, also linked a

Patients with stroke caused by bleeding on the brain (intracerebral haemorrhage) may benefit from receiving a drug currently used to treat blood loss from major trauma and bleeding after childbirth, an international trial has revealed. The study, led by experts at The University of Nottingham and funded by the National Institute for Health Research (NIHR)

Inflammation can be good. It’s part of the body’s innate immune system, our first line of defense against illness and injury. However, if the inflammatory response goes on for too long, it can lead to a condition called chronic inflammation, where the body essentially attacks itself, wreaking biological havoc on our organs and systems. Chronic

Sleep is known to be important for creative thinking, but exactly how it helps and what role each sleep stage—REM and non-REM—plays remains unclear. A team of researchers have now developed a hypothesis, outlined in an Opinion published May 15 in the journal Trends in Cognitive Sciences, to explain how the interleaving of REM and

A meditation and stress reduction program may be as effective at getting people to move more as structured exercise programs, according to a new study led by an Iowa State University researcher. The study compared two intervention programs—mindfulness-based stress reduction and aerobic exercise training—with a control group and measured changes in exercise, general physical activity

A fight with a spouse may end in hurt feelings, but for those with chronic conditions like arthritis or diabetes, those arguments may have physical repercussions as well, according to researchers. They found that in two groups of older individuals—one group with arthritis and one with diabetes—the patients who felt more tension with their spouse

Mental health problems are more common than we might think. The National Institutes of Mental Health (NIMH) estimate that 16.2 million people in the United States have experienced major depression at least once in the past year. Depression is considered the leading cause of workplace absenteeism in the U.S., as well as the leading cause

The National Institutes of Health (NIH) estimate that more than 30 million people in the United States live with type 2 diabetes. Many of the risk factors for diabetes are lifestyle habits that can be changed. Being physically active, eating right, and trying to maintain a healthy weight can all lower the risk. Some other

(HealthDay)—Resistance exercise training (RET) is associated with reduced depressive symptoms among adults, according to a meta-analysis published online May 9 in JAMA Psychiatry. Brett R. Gordon, from the University of Limerick in Ireland, and colleagues examined the correlation of efficacy of RET with depressive symptoms using data from 33 randomized clinical trials involving 1,877 participants.

Strength training is good for your body and your mind, according to a new review of more than 30 previously published studies. The paper, published in the journal JAMA Psychiatry, found that resistance exercise training (RET), such as weightlifting and strength training, is associated with a significant reduction in depressive symptoms. It also, of course,

Lung cancer is the second most prevalent form of cancer in men and women and the top cancer killer among both sexes. The American Cancer Society (ACS) estimate that in 2018, 154,050 people in the United States will have died from the disease. The World Health Organization (WHO) suggest that 1.69 million deaths are brought

A brain protein called tau is known to play a key role in the development of Alzheimer’s disease. Our brain cells have a “transport system” made of straight, parallel “roads,” along which food molecules, nutrients, and discarded parts of cells can travel. In a healthy brain, the protein tau helps these tracks to stay straight.

(HealthDay)—For reasons that aren’t yet clear, people who battle PTSD may also be at heightened risk for the common heart rhythm disorder atrial fibrillation, researchers report. It’s the first time a connection has been made between post-traumatic stress disorder (PTSD) and “A-fib,” which typically arises with age and is the most common type of heart

An FDA-approved drug can reverse an ionic imbalance in neurons that leads to hyper-excitability in mice modeling an autism-related genetic disorder, according to a Northwestern Medicine study published in Molecular Psychiatry. These findings suggest that the sensory hypersensitivity experienced by patients with fragile X syndrome, a syndromic autism, may be caused by elevated intracellular chloride

The percentage of people who died by suicide and who had opiates in their system more than doubled from 2006 to 2017, particularly in the most recent years, according to new research being presented today at the American Psychiatric Association’s Annual Meeting here. The rate of suicide in the U.S. is on the rise; about

Hypertensive adults with low platelet count who took a combined daily pill of both enalapril and folic acid saw a 73 percent reduction in their risk of first stroke compared to patients who took only enalapril daily, according to a study published in the Journal of the American College of Cardiology. Stroke is the second

A team from the University of Oxford and Cardiff University have used mathematical models to re-enact the complex process of brain development that occurs as initialising cells, otherwise known as progenitor cells, start to grow and begin to differentiate into more specialist cells at various points in time. By applying this experimentally realistic model to

Researchers have discovered a new family of substances which has been found to display highly potent activity against the release of pro-inflammatory cytokines and the toxicity induced by reactive oxygen species (ROS). The novel compounds synthesized and evaluated belong to a family of low molecular weight substances named indolines. In early experiments, these compounds have
