I knew it! Fiber is for cleaning the pipes. For cats, it's all about clearing upstairs pipes. Humans need it for downstairs pipes. 🧪🐈

What does grass and a drain snake have in common? Both contain jagged edges that help dislodge clumps of hair. Great for pipes--and, it turns out, also for cats. 🐱
Gold-covered hairballs may reveal why cats eat grass
Spiky projections on plant matter may act like “drain snakes,” helping felines dislodge wads of fur

@science.org exclusive! Scientists--and owners--have puzzled for years about why cats eat grass, only seemingly to throw it up for no reason. Could a new study finally solve the mystery? Cool--and very fun--story by Christa Lesté-Lasserre

“It’s the most challenging time I’ve ever seen for animal care." Facing enormous challenges, the USDA agency that oversees the animal welfare act--covering everything from lab to zoo animals--is struggling to do its job. The impact on animal welfare could be devastating. My latest for @science.org
Facing ‘impossible’ workload, USDA struggles to oversee lab animal welfare
Shrinking staff and other handicaps threaten enforcement of federal law that protects research animals

Honored to be featured on @sheltercatspodcast.bsky.social this week, where I do a deep dive into how cats and dogs evolved from wild animals to family members. I highly recommend the last 4 minutes, where I give my thesis statement about why cats are so special.

Extending up to 2.3 micrometers, this is the longest virus tail described to date--19 times larger than the tail of the coronavirus that causes COVID-19. Cool stuff from @nazeefa-ahmed.bsky.social for @science.org

Crab-like creatures are famed for having evolved five times in evolutionary history. But anteaters have evolved at least 12 times--in half the evolutionary span. Cool story by @jakebuehler.bsky.social for @science.org
‘Things keep evolving into anteaters.’ Odd animals arose at least 12 separate times

EXCLUSIVE @science.org: In an unorthodox approach to needle-free vaccines, researchers have developed a special kind of floss that can protect against infectious disease. “The results are quite impressive.” Cool story by @annikainampudi.bsky.social

Cover a person’s hand and place a rubber hand next to it, then stroke their hand and its facsimile, and suddenly the person will begin to “feel” the touch in the fake appendage. Octopuses also fall for this rubber arm trick. Cool story by @jasmin-galvan.bsky.social for @science.org
Octopuses fall for the ‘rubber arm’ illusion, just like us
Experiment shows octopuses feel body ownership, a trait previously seen only in mammals

Between June 2024 and January 2025, a full 62% of commercial honey bee colonies in the U.S. died, the largest on record. USDA efforts were slowed by funding cuts and layoffs. Now, USDA scientists have finally identified a culprit. But it may be too late. www.science.org/content/arti...

When exposed to UV-C, the most radiation-resistant life form on Earth died in less than a minute. Not so for a hardy black lichen known as Clavascidium lacinulatum. It just kept going and going, even when scientists continued to blast it for moths. Really cool story by @hannah-richter.bsky.social
