Unprecedented fires that raged in Canada and parts of the Amazon were at least three times more likely because of climate change, the first annual assessment of wildfires has shown. The first “state of wildfires” report – which is set to be published annually – assesses extreme wildfires that took place between March 2023 to February 2024, their causes, whether they could be predicted and how the risk of similar events will increase with future [...]

Researchers estimate that poor diet contributed to more than 14.1 million cases of type 2 diabetes in 2018. This represents more than 70% of new diagnoses across the world, the study suggests. The analysis, which looked at data from 1990 and 2018, provides insight into which dietary factors are driving the type 2 diabetes burden by world region. The findings are based on a research model of dietary intake in 184 countries, developed by researchers at the Friedman School of Nutrition [...]

Mice experiments have revealed that extreme levels of stress causes the sympathetic nervous system, which is responsible for the body’s rapid involuntary response to dangerous or stressful situations, to become hyperactive. This, in turn, drives the rapid depletion of stem cells responsible for hair colour, leading to pigment loss and development of [...]
