Killer whales 'massage' each other using kelp
Scientists have captured footage of orcas engaging in what looks like a spa day—using long strands of kelp to gently rub and "massage" each other. This playful behavior suggests these intelligent marine mammals might use seaweed not just for play, but possibly for social bonding or even skin care.
Editor’s Note: Beyond being adorable, this discovery adds to growing evidence that orcas are even more socially sophisticated than we thought. If they’re using kelp deliberately for comfort or connection, it challenges how we understand animal intelligence and social rituals. Plus, who doesn’t love the idea of whales giving each other seaweed back rubs?

Turns out, your grandpa might have been onto something with his gardening gear. While flashy electric tools dominate store shelves, this piece digs into why classic manual tools—think sturdy trowels and trusty pruning shears—still hold their own.

Editor’s Note: In a world obsessed with upgrades, this is a refreshing reminder that older doesn’t always mean obsolete. For gardeners, it’s not just nostalgia—these tools can save money, reduce waste, and even make the work more enjoyable. Plus, it’s a subtle nudge to rethink our "newer is better" default setting.
Weird space weather seems to have influenced human behavior on Earth 41,000 years ago – our unusual scientific collaboration explores how
NeutralScience
Scientists have uncovered a fascinating link between bizarre space weather—think intense auroras and cosmic radiation—and shifts in human behavior around 41,000 years ago. A quirky research collaboration suggests that our ancestors might have adapted their survival strategies in response to these celestial disruptions, though the exact "how" remains a mystery.
Editor’s Note: This isn’t just a fun "space did something weird" story—it hints at how deeply cosmic events might shape life on Earth, even in ways we’re only starting to piece together. If ancient humans really did tweak their behavior because of auroras or radiation, it adds a wild new layer to our understanding of human resilience. Plus, it’s a reminder that the universe isn’t just a backdrop; sometimes, it’s an active player in our history.
