Global Catastrophic Risk and the Drivers of Scientist Attitudes Towards Policy.

An anthropogenic global catastrophic risk is a human-induced risk that threatens sustained and wide-scale loss of life and damage to civilisation across the globe. In order to understand how new research on governance mechanisms for emerging technologies might assuage such risks, it is important to ask how perceptions, beliefs, and attitudes towards the governance of global catastrophic risk within the research community shape the conduct of potentially risky research. The aim of this study is to deepen our understanding of emerging technology research culture as it relates to global catastrophic risks, and to shed new light on how new research governance mechanisms might be developed.

Global policymakers and catastrophic risk.

There is a rapidly developing literature on risks that threaten the whole of humanity, or a large part of it. Discussion is increasingly turning to how such risks can be governed. This paper arises from a study of those involved the governance of risks from emerging technologies, examining the perceptions of global catastrophic risk within the relevant global policymaking community.

The Benefits of High-Intensity Interval Training on Cognition and Blood Pressure in Older Adults With Hypertension and Subjective Cognitive Decline: Results From the Heart & Mind Study.

The impact of exercise on cognition in older adults with hypertension and subjective cognitive decline (SCD) is unclear. We determined the influence of high-intensity interval training (HIIT) combined with mind-motor training on cognition and systolic blood pressure (BP) in older adults with hypertension and SCD. We randomized 128 community-dwelling older adults [age mean (SD): 71.

The role of surgical shunts in the treatment of pediatric portal hypertension.

Background: Portal diversion by surgical shunt plays a major role in the treatment of medically refractory portal hypertension. We evaluate our center's experience with surgical shunts for the treatment of pediatric portal hypertension.

Methods: All patients who underwent surgical shunt at a single institution from 2008 to 2017 were reviewed.
