We're turning the official semester Nunez lab photo into a tradition, and I'm absolutely here for it. Every semester it's a chance to see all the wonderful people doing science in my lab, both old and new. Feeling grateful for this amazing group and excited for what we'll accomplish together.

A breathtaking coastal night scene with a sky full of stars. The calm ocean reflects the faint glow of the night, while rugged coastal rocks stand silhouetted against the horizon. In the distance, the first light of sunrise begins to emerge, casting a soft, golden hue that blends seamlessly with the deep blues and purples of the night. The atmosphere is serene and magical, capturing the quiet beauty of the transition between night and day.

Crimson-collared Tanager at @tapirvalley.bsky.social #birds #costarica #nature
A striking bird perched on a slender branch in a lush green environment. Its body is adorned with deep black plumage, contrasting sharply with a vivid red head, neck, and chest. The bird’s small, stout beak is pale and sharply defined against its dark face, while its red eyes add an intense gaze. Tiny droplets of water cling to its feathers, suggesting a recent rainfall. The blurred green foliage in the background provides a natural, vibrant setting that enhances the bird’s brilliant colors.
