A new PNAS study fed more than three decades of black-browed albatross records into an evolutionary model, allowing traits such as wing length, breeding timing and behavior to change as the climate warms. The results show that so-called evolutionary rescue can extend the species' survival under mild warming, but that strong warming overwhelms this adaptive capacity, raising concerns about the long-term future of albatross populations.

A new long read examines the paradox of leadership and stress. It cites a 2012 PNAS study finding that leaders had lower cortisol levels and less anxiety than non-leaders, largely because leadership brings a greater sense of control. The piece argues the picture reverses when responsibility outpaces actual control, and when isolation strips away social support, leaving leaders worn down despite their apparent power.

A PNAS commentary argues that current tax and policy approaches risk undermining the workforce that sustains American science, warning that burdening researchers and skilled immigrants could weaken US innovation. It calls attention to how fiscal decisions affect the recruitment and retention of scientific talent, a concern gaining urgency amid funding pressures and global competition for researchers.
