Too many male animals in zoos could hamper conservation of endangered species, warn scientists

A large-scale study found that zoos are often breeding endangered animals in skewed sex ratios, which can limit genetic diversity and increase the risk of extinction. The research highlights the need for zoos to collaborate and share data on their animal populations to manage conservation efforts effectively.

Stepping for digital rewards

A study found that users who exchanged daily walking steps for digital train tickets increased their walking by an average of 626.2 steps/day. Those using shopping coupon incentives walked 715.2 steps/day more on average than non-users. The results suggest effective promotion of active travel through well-designed mHealth apps.

Researchers find interbreeding intervention for Florida panthers decreased effects of harmful mutations

A recent study by UCLA researchers found that introducing new genetic variation from Texas reduced the influence of harmful mutations in Florida panthers, improving their fitness. However, the effect of this intervention may be temporary, and continued protection is needed to preserve the subspecies.

Neighborhood watch: why closely related tropical animals live together

A study published in the Royal Society's Proceedings B found that closely related bat and bird species share the same habitat due to their shared evolutionary history. This challenges previous ideas about competition driving species apart, suggesting that animals with similar needs tend to group together in suitable habitats.

Immune ‘bouncers’ protect the brain from infection

Researchers at WashU Medicine discovered that mast cells stand guard at tiny gates through which fluid waste leaves the brain, mounting a response when a pathogen is detected to close the gates and prevent invaders from entering. Enhanced mast cell activity before an infection reduced bacterial load.
