Water droplets might seem simple at first. But when nearing evaporation, a desperate power struggle of competing physical forces can emerge, with explosive effects. In a Proceedings of the National Academy of Sciences publication, researchers have taken a closer look at the physics of charged water droplets on frictionless surfaces, observing spontaneous jets of microdroplet emissions. Their insights may open new opportunities in nanoscale fabrication and electrospray ionization. ... Read full Story
Merriam-Webster's Word of the Day for May 4, 2026 is:
scrupulous \SKROO-pyuh-lus\ adjective
Scrupulous describes someone who is very careful about doing something correctly, or something marked by such carefulness. Scrupulous can also describe someone who is careful about doing what is honest and morally right.

// Less scrupulous companies find ways to evade the law.
“Scrupulous directors make sure that the sound of their movies is grossly efficient, so that the dramatic meaning of a scene is apparent even in the worst theatre or home system in the country …” — David Denby, The New Yorker, 9 Mar. 2026
Did you know?
People described as scrupulous might feel discomfort if their work is not executed with a sharp attention to detail. Such discomfort might present itself as a nagging feeling, much as a sharp pebble in a shoe might nag a walker intent on getting somewhere. And we are getting somewhere. The origin of scrupulous is founded in just such a pebble. Scrupulous and its close relative scruple (“a feeling that prevents you from doing something that you think is wrong”) both come from the Latin noun scrupulus, “a small sharp stone,” the diminutive of scrupus, “a sharp stone.” Scrupus has a metaphorical meaning too: “a source of anxiety or uneasiness.” When the adjective scrupulous entered the English language in the 15th century, it described someone careful about preserving their moral integrity, but it now is also commonly used for someone who is careful in how they execute tasks.
