Childhood trauma leaves mark on DNA of some victims

A study by Max Planck Institute of Psychiatry found that genetic variants of the FKBP5 gene can influence epigenetic alterations caused by early trauma, leading to lifelong dysregulation of stress hormones. This can result in increased risk of depression, post-traumatic stress disorder, and anxiety disorders in adulthood.

Shifting the safety balance for overnight workers

A new screening tool has been developed to help identify individual vulnerability to health and safety impacts of shift work. The tool, for a condition known as shift work disorder, aims to reduce workplace accidents and illnesses caused by shift work, including cardiovascular disease and cancer.

Record high for global carbon emissions

Global carbon dioxide emissions are projected to rise by 2.6% in 2012, reaching a record high of 35.6 billion tonnes, with China contributing 28% and the US 16%. The analysis highlights the urgent need for radical emission reductions to keep global warming below 2 degrees.

Gap between present emissions and the 2-degree target

The Global Carbon Project warns that current trends are no longer aligned with the goal of limiting global warming to 2°C. To bridge this gap, a sustained global CO2 mitigation rate of at least 3% is needed to peak emissions before 2020 and follow an emission pathway that can keep temperatures below 2˚C.
