Experts argue that campaigns focusing on climate science consensus are likely to backfire and fuel debate rather than promoting policy efforts. The messaging strategy promotes confusion over the extent of consensus and has an uncertain evidence-base.
A recent study published in the International Journal of Radiation Biology found that low doses of radiation can cause permanent alterations in coronary artery endothelial cells, leading to reduced nitric oxide production and increased oxidative stress. This damage can result in long-term premature dysfunction and an increased risk of ...
A study in the journal Temperature found that high temperatures can lead to a 27% labor loss and 15% decrease in work time for grape-picking workers in European wine production. The research highlights the potential negative impact of global warming on the industry, which is a significant contributor to world GDP.
The use of remote sensing technologies has the potential to revolutionize the management of the oil palm industry, providing quick and accurate information on huge areas of oil palms. Key applications include identifying lands suitable for expansion and improving yield prediction accuracy.

A new study published in the Journal of the American College of Nutrition found that vegetarian diets are more effective than conventional low-calorie diets in reducing body weight. Vegetarian diets also improve glucose and lipid metabolism, which is particularly important for people with metabolic syndrome and type 2 diabetes.
Researchers compared visual functions in elite and intermediate footballers to healthy non-athletes, finding that elite players had better visual clarity, contrast sensitivity, and near-far quickness. Defensive players showed faster near-far quickness than offensive players, suggesting this may be an advantage for defenders.
Parents' understanding of antibiotic risks and watchful waiting approaches can significantly impact their adherence to delay antibiotic use for common childhood illnesses. By enhancing physician instruction, compliance rates with this approach could be increased, potentially reducing unnecessary antibiotic overuse.
