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.

Lung cancer patients with pockets of resistance prolong disease control by 'weeding the garden'

Researchers have found that targeting resistant lung cancer 'pockets' with focused radiation can prolong disease control in patients who initially respond to crizotinib or erlotinib. This approach showed significant benefits in patients whose cancers progressed in the brain, where the drugs are less effective.

Long-term research reveals how climate change is playing out in real ecosystems

A recent study published in BioScience reveals surprising results on the effects of climate change on ecosystems, highlighting the value of long-term ecological research. The analysis shows how changes in temperature and precipitation affect hydrologic variables, plant and animal community composition, and ecosystem services.

Making sustainability policies sustainable

Researchers examine China's massive Grain to Green Program, which has invested over $32 billion to persuade farmers to return cropland to forest and grassland. The study found that too much land is being enrolled in the program in flat areas, and policymakers need to communicate more with farmers to better understand their needs.

Wayne State part of international effort to understand chemical movement, processes in oceans

A Wayne State University researcher is part of an international effort to study the movement of chemical compounds through the world's oceans. The project aims to investigate how carbon is exported from the upper 100 meters of ocean water to deeper waters and how hydrothermal waters affect the removal of polonium and lead.

Researchers discover how C. diff red lines immune response

A recent study published in PLOS One reveals that a common diarrhea-causing bacterium triggers an overactive immune response, worsening illness in hospital-acquired infections. Researchers found that activating a protective mechanism involving the PPARgamma pathway can reduce disease severity and be activated by existing diabetes drugs.

Penn Study finds residents believe vacant land threatens community, physical and mental health

Residents in a new study by University of Pennsylvania researchers emphasize the negative impact of vacant land on physical and mental health. Participants expressed concerns about crime, stress, and feelings of helplessness when confronted with vacant lots, which often harbor garbage, vermin, and other hazards.

Hospital cleaning protocol ineffective against A. baumannii

Researchers found that hospital cleaning protocols are often inadequate to remove multidrug-resistant Acinetobacter baumannii from patient rooms, with over half of rooms still contaminated after terminal cleaning. Persistent room contamination poses a risk for future patients, highlighting the need for improved infection control measures.
