Measuring broken hearts: divorce has negative effects on physical and mental health

Going through a divorce is extremely challenging and previous research has highlighted the adverse effects that it can have on divorcees. A recent study in open-access journal Frontiers in Psychology is the first to examine health impacts immediately after a divorce. The study found that the mental and physical health of recent divorcees was worse […]

First recommendation of its kind in new global guidelines on physical activity and sedentary behavior — ScienceDaily

New additional research shows that increasing physical activity can counter early death risk linked to long periods of sedentary time The health harms associated with prolonged sitting can be offset by exceeding weekly recommended physical activity levels, says the World Health Organization (WHO) in new global guidelines on physical activity and sedentary behaviour, published in […]

Physical distancing polices not enough to protect lower-income people: BU study

A new Boston University School of Public Health study of the first four months of America’s coronavirus epidemic, published in the journal Nature Human Behaviour, shows that physical distancing (also called “social distancing”) policies had little effect on lower income people still needing to leave their homes to go to work–but does show them staying […]

Melding biology and physical sciences yields deeper understanding of cancer — ScienceDaily

An evolving understanding of cancer that incorporates the physical properties of tumors and their surrounding tissues into existing biologic and genetic models can direct cancer researchers down previously uncharted avenues, potentially leading to new drugs and new treatment strategies, say investigators from Massachusetts General Hospital (MGH), Harvard Medical School (HMS) and the Ludwig Center at […]

Long-term data show a recent acceleration in chemical and physical changes in the ocean — ScienceDaily

New research published in Nature Communications Earth & Environment uses data from two sustained open-ocean hydrographic stations in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The study shows decadal variability and recent acceleration of surface warming, salinification, deoxygenation, and changes in carbon dioxide (CO2)-carbonate […]
