Ripple Bugs
Ripple bugs are a type of water strider capable of moving at a blazing fast 120 body lengths per second across the water surface. In addition to their speed, ripple bugs are incredibly agile and are active almost constantly. (Video credit: Science; research credit: V. Ortega-Jimenez et al.)
I am such a hydrophilic person that I can lie in the bath for 4-5 hours. Actually, that is why I usually take a shower and not a bath. Otherwise, I would live in it.
Turning everyday filter paper into a miniature microfluidic platform with DLP 3D printing
Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, designed in different geometries, guide liquids along precise paths and shape their flow behavior, demonstrating effective use in mixing, gradient generation, and two-phase separation within miniaturized systems. Filter paper properties and potential Filter paper plays important roles in everyday laboratory work, from simple solid-liquid separation to chromatography, thanks to its microstructural properties. It is composed of small paper fibers, forming a network with different densities throughout the sheet, allowing different grades to be manufactured for different uses. A denser fiber distribution produces smaller pores, which affects the hydrophilicity and overall performance of the filter paper.

Science Teacher Moments
Teaching about solubility and water as the universal solvent:
Me: and so another word for nonpolar is hydrophobic, aka afraid of water.
Students: *nod with understanding of the root words*
Me: and therefore, another word for polar is hydrophilic, or water-loving.
Students: *blank looks*
Me: like how Philadelphia is "the city of brotherly love" same root word.
Students: *blank looks*
Me: ok, then let me give you a different word that maybe will connect better for you.
Me: necrophilia!
Students: *horrified looks*
Me: well, you'll remember it now, won't you!
