A new study published in *Nature Communications* finds that small mammals that are highly adapted to specific climates tend to evolve more rapidly, while older groups of mammals simply accumulate more species over time. Researchers analyzed thousands of species worldwide and discovered that nearly 40% of small mammals live in very narrow climate conditions, and many of these have diversified quickly. However, older families of mammals don't necessarily diversify faster, they just have had more time to build up their number of species. The study suggests that climate specialization can drive rapid evolution, but the passage of time plays a bigger role in how many species exist in a group.
Why it matters: This research helps explain why some animal groups become extremely diverse while others remain limited in species count. It highlights the complex relationship between environmental adaptation and evolutionary history.

A new study shows that patterns of daily activity, like when people wake up and go to sleep, can reveal signs of how fast someone is aging. Researchers used data from thousands of people wearing Fitbit devices over several years and compared it to biological markers of aging. They found that people with more consistent and intense daily rhythms, like waking up at the same time every day, tended to age slower. Women showed stronger links between activity patterns and aging than men, while men who had irregular schedules experienced faster aging. This suggests that everyday wearable devices could one day help track aging and health risks on a large scale.
Why it matters: This research connects everyday behavior tracked by common fitness trackers to real biological changes linked to aging. It opens the door to using widely available technology for early detection of aging-related health issues.
