Scientists discover a hidden brain “cleaning” effect triggered by movement
Regular physical movement may do more for your brain than previously understood. Researchers have found that contracting your core muscles triggers pressure changes in blood vessels that cause the brain to subtly shift within the skull, driving the circulation of cerebrospinal fluid. This fluid movement appears to help clear toxic waste from the brain, suggesting even minor physical activity could play a direct role in neurological health.

Plant-based diets cut climate impact by more than half, randomized clinical trial shows
Switching to a plant-based diet could be one of the most immediate and impactful steps individuals can take against climate change. A randomized clinical trial published in *Current Developments in Nutrition* found that participants following a low-fat vegan diet cut their diet-related greenhouse gas emissions by 55% and energy demand by 44% in just 12 weeks. The findings add rare clinical rigor to the growing body of evidence linking dietary choices to environmental outcomes.

Proton beam timing tool could check radiotherapy energy before nearly every treatment
Researchers at Poland's Institute of Nuclear Physics have developed two tools that use beam timing data to verify proton energy levels before radiotherapy sessions. The advance addresses a critical quality-control gap in proton therapy, where beam accuracy directly determines whether treatment destroys tumors or damages surrounding healthy tissue. Routine pre-treatment verification could significantly reduce delivery errors and improve patient outcomes.

Hidden plant molecules show up to 25 times stronger activity against Ebola and COVID-19
Researchers at Montreal's Clinical Research Institute have uncovered a previously overlooked family of plant-derived molecules that demonstrate antiviral activity up to 25 times stronger than existing compounds against both Ebola and SARS-CoV-2. The findings add a promising new lead to the global search for broad-spectrum antivirals drawn from natural sources. With pandemic preparedness increasingly urgent, the discovery could accelerate development of next-generation treatments ahead of future outbreaks.
