Scientists Solve Century-Old Feline Mystery

Animals often rely on scent marks to communicate identity across time, yet how chemically dynamic signals remain individually informative is unresolved; Ichizawa et al. show that domestic cats achieve durable chemical individuality through a reservoir-buffered system based on branched-chain fatty acid. Image credit: Ichizawa et al., doi: 10.1016/j.cub.2026.07.045.

For nearly 110 years, biologists have puzzled over why domestic cats’ kidneys are packed with unusually large numbers of fat-storing structures called lipid droplets. Professor Masao Miyazaki of Iwate University and colleagues suggest that these kidney droplets serve as a chemical reservoir, helping cats maintain a stable ‘scent signature’ in their urine even as the odor changes over time. Animals...

Australia’s North Pole Dome Crater is Earth’s Oldest and Only Known Archean Impact Structure

The North Pole Dome crater: (A) simplified map of the East Pilbara Terrane (EPT, Western Australia), showing Paleoarchean granite domes (pink) and greenstone belts (greens and blues); the North Pole Dome (NPD) lies near the terrane center; (B) geological map of the NPD and the shatter-cone field (yellow star); (C) A quartz (Qtz)-carbonate vein cutting shatter-cone lineation.
