There’s No Such Thing As Too Many Hobbies—A Psychologist Explains
Some people come to therapy feeling overwhelmed and uncertain about their tendency to pick up and put down hobbies on a whim. They ask questions like:“Why do I feel so scattered, hopping from one interest to another?”
“Is it normal to want to learn so many things, or am I just avoiding commitment?”“Why do I feel like I’m not truly excelling in any one area despite my many pursuits?”
The pervasive cultural narrative has often celebrated specialization, making those with multifaceted interests feel out of place. Society has long valued depth over breadth, equating mastery in a single field with success and purpose. This has led to a collective anxiety: the fear of missing out on becoming an… More.
While we once frowned upon the “jack of all trades,” an array of hobbies might reveal a quest for a psychologically rich life—one that fosters depth, curiosity and growth.
Researchers find high concentrations of microplastics in cave water and sediment
In two recent papers, Saint Louis University researchers report finding high concentrations of microplastics present in a Missouri cave system that had been closed to human visitors for 30 years.
Elizabeth Hasenmueller, Ph.D., associate professor of Earth and Atmospheric Sciences and associate director of the WATER Institute at SLU, and her team published findings in the journals, Science of the Total Environment and Water Research, finding significant microplastic levels in Cliff Cave in Saint Louis County, Missouri.
The research, which originated from Hasenmueller’s research group and Karst Hydrology class, allowed students on the team to participate in field research and publish their findings.

New model describes synchronized cilia movement driven by border regions
What do the crowd at a football stadium, the feet of a centipede, and the inside of your lungs have in common? All of these systems show the same specific kind of organization, as recently discovered by a group of scientists from MPI-DS.
The crowd wave in a stadium looks like a pattern traveling across the tiers. Similarly, the legs of a centipede move in canon with illusory waves sweeping along its entire length. On a microscopic level, tiny hairs in our lungs called cilia wave together to transport mucus. This serves as a first line of defense against invading pathogens.
To create a synchronized and efficient wave, cilia need to accurately coordinate their beating motion. Unlike football fans watching their neighbors and the nervous system coordinating the centipede’s legs, cilia have no such intelligent control system.
Dolphins learn the ‘names’ of their friends to form teams—a first in animal kingdom
Like members of a street gang, male dolphins summon their buddies when it comes time to raid and pillage—or, in their case, to capture and defend females in heat. A new study reveals they do this by learning the “names,” or signature whistles, of their closest allies—sometimes more than a dozen animals—and remembering who consistently cooperated with them in the past. The findings indicate dolphins have a concept of team membership—previously seen only in humans—and may help reveal how they maintain such intricate and tight-knit societies.
Findings reveal the marine mammals have a sense of team membership.
