How do air filters work?

How do filters remove particles from the air and reduce exposure - especially the small ones? As this Risk Bites primer shows as it dives into the science of aerosol particle capture, it may not be how you think! Air filters are an important tool for protecting health, improving air quality, and reducing air pollution by removing potentially harmful particles from the air you breathe. But how they work isn't that intuitive -- especially at small particle sizes. #filter #risk #dust #exposure USEFUL LINKS Video techniques for effective science communication: https://riskinnovation.asu.edu/video-techniques/ RISK BITES Risk Bites videos are devised, created and produced by Andrew Maynard, in association with the Arizona State University School for the Future of Innovation in Society (http://sfis.asu.edu).

Is this America's most bizarre Thanksgiving Dish?

Okay so this has nothing to do with risk. Or science (sort of). But I couldn't resist making it! I love Thanksgiving. This has to be one of the best holidays, period. Negligible commercialization, great food, and a chance to relax, catch up with family and friends, and contemplate everything you

What's a gene drive?

A gene drive is a radical new way of re-engineering the genetic makeup of an entire species - including harmful insects like the mosquito. But as the technology steams head, fueled by powerful gene editing techniques coming out of synthetic biology like CRISPR Cas9, what are the risks, and how can w
