A new study published today in JAMA Network Open projects that reductions in federal funding for syringe service programs (SSPs) could lead to substantial increases in mortality among people who inject drugs in the United States. The worst-case scenario projected 39,600 additional deaths and 15,600 additional overdose deaths.

National and international security alike depend on the military being both willing and able to comply with the political preferences of a civilian-led government – but how can we accurately describe the role of the military in politics? Drawing on a new theory of military compliance and a method for structured, theory-grounded analysis, a doctoral thesis at Åbo Akademi University in Finland presents a new framework for describing the role of the military in foreign policy. The thesis applies the framework to Putin’s military campaigns in Georgia and Syria.

Ensuring the research that we all rely on – whether for our health, environment or economy – is trustworthy is important for universities, governments and business. A new study sheds light on the key factors that drive research misconduct in universities, offering crucial insights for strengthening research integrity worldwide.

A major global analysis led by the University of Bath in the UK finds policy reform that removes criminal penalties for cannabis possession, or introduces tightly controlled legalisation, is not associated with increased levels of use. However, legalisation that allows cannabis to be sold for profit is followed by increases in use, addiction and psychiatric hospital admissions.

Women who lift weights may have a lower risk of major heart disease, especially when combined with aerobic exercise, according to a new study published today in JACC, the flagship journal of the American College of Cardiology. Findings show that heart health is better understood by looking at overall movement habits, rather than focusing on single behaviors alone, and resistance training can result in additional health benefits when incorporated into an active lifestyle.
