microneedle patch

Caption: 

In healthy adults, a flu-vaccine patch (seen here) packed with “microneedles” painlessly delivers a dose of flu vaccine and causes only mild side effects — ones similar to what a traditional flu shot causes.

frying egg

Caption: 

Many old-style nonstick frying pans relied on coatings containing PFOA or related perfluorinated compounds. Although there has been a move to alternative coatings, these perfluorinated pollutants live on in the environment. And that is driving new research aimed at removing them.
