Galaxies ‘Dance’ In Stunning New JWST Image | Why Some Cats Scratch Furniture

As the James Webb Space Telescope marks two years of operations, NASA unveils a new image of two galaxies interacting. And, new research shows that cats’ tendency to scratch is affected by stress, certain kinds of play, and how active they are at night.

Galaxies ‘Dance’ In Stunning New JWST Image

The James Webb Space Telescope, the most powerful telescope created by humans, has been successfully operating in space for two years now. Since its launch, the telescope has dazzled astronomers and the public with new kinds of scientific data about the universe and with stunning, highly detailed pictures. And on its two-year anniversary, the telescope continues to return impressive visuals: NASA released a mesmerizing image today of two intermingling galaxies nicknamed the Penguin and the Egg.

Jason Dinh, climate editor at Atmos, joins guest host Kathleen Davis to talk about that and other top science stories of the week, including a new study that shows that children with autism have a unique microbiome, new FEMA rules that factor in climate change when rebuilding in flood-prone areas, and how invasive insects use hitchhiking to spread their populations.

Why Some Cats Scratch Furniture So Much

If you have a cat, you’ve probably endured your fair share of unwanted furniture scratching. Maybe you’ve purchased scratching posts, rearranged your furniture, or played with your cats before bed, to try to prevent it. And yet, you wake up to shredded upholstery or bedding.

Furniture scratching is often a stress response, and cats who live with kids or are more playful and active at night are more likely to scratch.

SciFri producer Kathleen Davis spoke with Dr. Yasemin Salgirli Demirbas, a physiology professor at Ankara University in Turkey and visiting fellow at the Atlantic Veterinary College at the University of Prince Edward Island, about her recently published study which tracked why some cats are more prone to scratching destruction than others and explored the best way for cat owners to achieve a mostly intact living room.
