In a 2025 study, researchers show the grass species felines eat tend to be jagged and covered in spikelike projections. That allows them to latch onto intestinal hairballs, the team proposes, potentially helping cats dislodge them. Learn more: scim.ag/4ntn8VB #ScienceMagArchives

At the center of my message to faculty yesterday was: 1.) We may not be adequately prepared for how angry students are about tech. 2.) They are not all angry for the same reasons. 3.) Being angry at it doesn’t mean they aren’t using it. The sense of entrapment fuels the anger.
