Ocean circulation in North Atlantic at its weakest

A recent study by HKU researchers found that ocean circulation in the North Atlantic is at its weakest since the past 1,500 years. The weakening of the Atlantic Meridional Overturning Circulation (AMOC) is attributed to global warming and associated melt of the Greenland Ice-Sheet, which has significant implications for climate change.

Climate change predicted to end truffle production

A new study predicts that climate change will lead to a decline of 78-100% in European truffle production between 2071 and 2100, with significant economic and social impacts. The study highlights the need for conservational initiatives and management strategies to mitigate soil temperature fluctuations and conserve soil moisture.

Powerful new map depicts environmental degradation across Earth

A powerful new map by the University of Cincinnati illustrates dramatic changes in land use over the last quarter century, showing widespread deforestation and urbanization. The map highlights the devastating effects of climate change on the environment, including the shrinking Aral Sea and growing desertification in the Sahara Desert.

ESCMID defines generic competencies in antimicrobial prescribing and stewardship

A new set of generic competencies has been established by ESCMID to guide healthcare professionals in using antibiotics responsibly. The competencies cover three main areas: antimicrobial prescribing, diagnosing infections, and stewardship. This framework aims to harmonize approaches to antibiotic use across Europe.

History of early settlement and survival in Andean highlands revealed by ancient genomes

Researchers uncovered genetic adaptations in ancient Andeans, including cardiovascular modifications and a starch-digesting enzyme variant, allowing them to thrive in the harsh environment. The study suggests that these adaptations enabled highlanders to survive European contact with less population decline than lowlanders.

Oldest evidence of dairying on the East Asian Steppe

Researchers discovered dairy pastoralism in Mongolia as early as 1300 BC through cultural transmission rather than population replacement or migration. Milk proteins were found in tooth tartar and dental calculus of ancient Mongolians, indicating the livestock were cattle, sheep, and goats introduced by Western Steppe herders.

Updated European guidance for the diagnosis and management of osteoporosis in women

The new guidelines review and update the 2013 European guidance for diagnosing and managing osteoporosis in postmenopausal women. Key findings include the importance of evaluating bone microstructure and using FRAX tools in fracture risk assessment, as well as the need for long-term dietary intakes and monitoring drug treatment.

Tobacco smoking pre-dated European contact in Pacific Northwest

Researchers found biomarkers of nicotine in 1,200-year-old stone pipes from the Columbia River Basin, challenging the idea that bearberry was the main ritual smoke plant. The discovery establishes a history of ritual tobacco use in the interior Pacific Northwest, informing education and smoking abatement programs.

Can forests save us from climate change?

A new study published in Nature found that sustainable forest management can only provide modest, local benefits rather than a significant impact on the global climate. Forests themselves will need to be adapted to climate change to sustain their ecological and social services.

Physical activity has health benefits for smokers, regardless of air pollution levels

A new study finds that regular physical activity improves lung function in current smokers, regardless of air pollution levels. The study, led by the Barcelona Institute for Global Health, analyzed data from over 4,500 people and found that physical activity benefits even in areas with high air pollution.

Long-term exposure to ozone has significant impacts on human health

A new study by Duke University and the University of York estimates that long-term ozone exposure in Europe, the USA, and China led to 266,000 premature mortalities in 2015. The research uses observed air quality data instead of chemical transport models, finding smaller human-health impacts compared to prior modeling results.
