Study Of 27.8M Americans May Have Revealed Direct Alzheimer’s Cause
Scientists have just found a direct link between air pollution and Alzheimer’s disease—suggesting that improving air quality could be an important way to prevent dementia and protect older adults. Alzheimer’s disease is the most common form of dementia, which affects about 57 million people worldwide, and there is currently no cure for it, making prevention is crucial. (Azzurra Volpe, 2/17)

Mark Zuckerberg Set To Testify In Watershed Social Media Trial
Mark Zuckerberg will testify in an unprecedented social media trial that questions whether Meta’s platforms deliberately addict and harm children.

FDA Investigating Salmonella Outbreak Connected To Moringa Powder
Public health officials are investigating a Salmonella outbreak linked to Rosabella-brand moringa powder, according to the U.S. Centers for Disease Control and Prevention. The CDC, Food and Drug Administration and state public health officials are looking into drug-resistant Salmonella infections linked to some lots of the product. Seven illnesses, three of which resulted in hospitalizations, across seven states could be linked to the Rosabella capsules, according to the FDA, which said it continues to investigate the outbreak. At least one Salmonella case has been reported in Arizona, Florida, Iowa, Illinois, Indiana, Tennessee and Washington. (Cerullo, 2/17)

Study: SARS-CoV-2 RNA Found In 39% Of Hospital Air Samples During Outbreaks, Despite Good Ventilation
COVID-19 genetic material was frequently detected in hospital air during community outbreaks, even in well-ventilated settings, according to a new study published in Respiratory Medicine. A team led by Kirby Institute researchers conducted air and surface sampling in the emergency department (ED) and intensive care unit (ICU) of a large metropolitan hospital in Sydney, Australia, during two COVID-19 waves between November 2023 and July 2024. Their testing found that 39% (20 of 51) of aerosol samples were positive for SARS-CoV-2 RNA. (Bergeson, 2/17)

Excruciating Tropical Disease Can Now Be Transmitted In Most Of Europe, Study Finds
An excruciatingly painful tropical disease called chikungunya can now be transmitted by mosquitoes across most of Europe, a study has found. Higher temperatures due to the climate crisis mean infections are now possible for more than six months of the year in Spain, Greece and other southern European countries, and for two months a year in south-east England. Continuing global heating means it is only a matter of time before the disease expands further northwards, the scientists said. (Carrington, 2/18)
