Food can trigger overconsumption similar to alcohol and drugs, but it is not the whole story

A large analysis of personality studies has found that people with obesity behave somewhat like people with addictions to alcohol or drugs. But obesity is also a complex condition that cannot be fully explained by the addiction model.

The loss of biodiversity continues at an alarming rate despite decades of research and international policies setting out clear goals in the area. In an article published this week in Nature Sustainability, an international team of scientists including researchers from McGill identified seven key areas for future research in order to tackle, effectively, the root causes of the problem.

It鈥檚 a proven way to improve patient safety and outcomes, and meet the evolving health needs of the aging Quebec population. It鈥檚 a way to make higher education in nursing available to all communities in the province. It鈥檚 a way to increase the pool of potential candidates for graduate-level education to produce the next generation of nurse leaders, researchers and educators, as well as nurse practitioners. It鈥檚 a way to ensure more nurses have the required level of training if, and when, Quebec follows all other Canadian provinces and requires a nurse to have a university-level education.

Wastewater-based epidemiology is a rapidly developing scientific discipline with the potential for monitoring close to real-time, population-level trends in illicit drug use. By sampling a known source of wastewater, such as a sewage influent to a wastewater treatment plant, scientists can estimate the quantity of drugs used in a community from the measured levels of illicit drugs and their metabolites excreted in urine.

A new study, published in Science, which focuses on mapping biodiversity change in marine and land ecosystems shows that loss of biodiversity is most prevalent in the tropic, with changes in marine ecosystems outpacing those on land. The research, led by scientists from the University of St Andrews, in collaboration with leading universities across Europe, the USA and Canada, including McGill, aimed at reaching a consensus about variation in biodiversity change.

Nature supports people in critical ways, often at a highly local level. A wild bee buzzes through a farm, pollinating vegetables as it goes. Nearby, wetlands remove chemicals from the farm鈥檚 runoff, protecting a community drinking water source. In communities all around the world, nature鈥檚 contributions are constantly flowing to people. A team of international scientists including from 香蕉视频, have mapped these contributions at local levels for years, but a new Stanford-led study closes a critical gap in how this information can be used to drive global policy and development.

The diversity of life is staggering. From microscopic algae to elephants, life has devised countless ways to thrive in every environment on the planet. But while biologists have tended to focus on the many varied forms that species have evolved, the age of 鈥榖ig data鈥� offers an unprecedented view of some surprisingly common features shared by all creatures, great and small.
