Models to predict dengue, zika and yellow fever outbreaks are developed by researchers

A groundbreaking study aims to create predictive models to monitor and combat epidemics of yellow fever and other mosquito-borne diseases. By analyzing factors such as deforestation, rainfall variations and non-human primate populations, researchers hope to develop models that can predict outbreaks and protect the public.

Oxidation processes in combustion engines and in the atmosphere take the same routes

A research team at TROPOS and University of Helsinki has discovered that alkanes in fuels produce highly oxygenated compounds that can form organic aerosol and contribute to air pollution. The study uses state-of-the-art measurement technology to demonstrate an efficient autoxidation chain reaction for saturated hydrocarbons.

For students of color, online racism leads to real-world mental health challenges

A recent study found that online racism has a significant impact on the mental health of college students of color, even more so than in-person experiences. The study suggests that social media platforms can be a breeding ground for racialized aggressions and assaults, which can lead to real and significant mental health impacts.

Low-level jets create winds of change for turbines

Researchers found that low-level jets can increase power production by up to 30% when positioned below turbines. Turbines placed above or at the same height as LLJs experience reduced efficiency due to blocked airflow. The study highlights the importance of optimizing turbine height for maximum energy capture.

Climate impacts drive east-west divide in forest seed production

A new study finds that eastern forests are more responsive to climate change, with younger trees increasing their seed production. In contrast, older western trees have been less responsive, which could limit their ability to regenerate after diebacks. The study reveals a continental divide in forest responses to climate change.

Study finds COVID risk communication targeting younger adults may have biggest impact

A US study suggests that young adults (under 40) perceive COVID-19 risks differently than older generations, with lower perceived risk and fewer preventive measures taken. Effective targeted communication efforts could encourage more risk reduction behaviors among younger generations.

'Missing ice problem' finally solved

Climate researchers at the Alfred Wegener Institute have developed a new method to reconcile sea-level height and glacier thickness, advancing our understanding of past climate history. By analyzing sediment cores and geological conditions, they found that glaciers were larger than previously thought, resolving the 'missing ice problem'.
