As measles cases rise, views of MMR vaccine safety and effectiveness -- and willingness to recommend it -- drop

A new survey by the Annenberg Public Policy Center finds a small but significant drop in the proportion of the public that would recommend getting the MMR vaccine, citing concerns over its safety and effectiveness. The survey also shows declines in perceived safety and effectiveness for other vaccines, such as seasonal flu and Covid-19.

Embargoed: New evidence points to potential treatment for vascular dementia

Researchers at the University of Vermont discovered that adding a missing phospholipid back into the circulatory system could restore normal brain blood flow and reduce symptoms of dementia. Boosting PIP2 levels may become a new treatment strategy to enhance brain function and prevent neurovascular diseases.

Online platform algorithmic control and gig workers’ turnover intention in China: The mediating role of relative deprivation

A new study reveals that algorithmic control's three-dimensional functions exert significantly different impacts on gig workers' turnover intention. Behavioral constraints and tracking evaluation exacerbate relative deprivation, while standardized guidance mitigates this effect, directly reducing turnover intention.

When satellites fall short: How 5G and GNSS team up for reliable urban positioning

A new study presents a deeply integrated positioning approach combining commercial 5G signals with Global Navigation Satellite Systems (GNSS) to overcome limitations in dense cities. The method significantly improves both ranging stability and positioning accuracy, delivering reliable performance even in heavily obstructed environments.

Capturing the moment a cell shuts the door on free radicals

Researchers at Lund University have discovered a cell's protective mechanism against excessive hydrogen peroxide, a key free radical. The study shows that the channel in the cell membrane closes automatically when high concentrations of hydrogen peroxide are detected, preventing damage and cell death.
