A study of nomadic pine siskins, a type of finch often seen on backyard feeders, found that when male migratory siskins were paired with a settled male bird in captivity, they started exhibiting signs of ending migration too. They stopped restless flying and lost body mass, fat stores and muscle size, compared to a control group placed in solo enclosures. The apparent reliance on social cues for the end of migration has implications for other nomadic animals as well.

Scientists and other experts are calling on governments to start including animal welfare in sustainable development governance now in order to work towards a healthier, more resilient, and more sustainable world for all.

The National Guard Bureau has taken a bold step toward securing and enhancing Warfighter brain health, and ensuring cognitive combat readiness with the launch of a new initiative to measure, track and improve cognitive performance and psychological well-being. The Warfighter Brain Fitness program is a research protocol with almost 1,000 participants across the United States. In partnership with Applied Research Associates, Inc., the Center for BrainHealth® at The University of Texas at Dallas, Posit Science, and Cortical Metrics, the Warfighter Brain Fitness program will collect data to optimize the online delivery of scientifically validated cognitive training approaches to reserve and active-duty populations.

Researchers from McGill University have identified a form of chemical signaling in mice to defend their offspring. The researchers found that proximity to pregnant and lactating female mice increased stress hormones in males and even decreased their sensitivity to pain.
