Thrilled to see this published today! Truly special because we made the initial discovery >15 yrs ago! We found two copies of a human gene called BC200 embedded in a human poxvirus. BC200 blurs the line between gene & transposon—both functional & mutagenic! www.science.org/doi/10.1126/... 🧵1/n

Chromosomal inversions are both engines of repeatability and innovation. They drive parallel genetic divergence between snail ecotypes across Europe, while also harbouring local variants that contribute to site-specific trait variations and adaptation: doi.org/10.1093/jeb/... Pajot et al 2026

This beautiful dictionary of colours found in nature dates back to more than a century before Pantone. 🎨 Werner's Nomenclature of Colour was an indispensable resource for Charles Darwin, helping him describe new species. We love these natural colours - which page do you like best?
A page of an old book titled “Blues” with a chart of different shades, naming each shade with an example of an animal, vegetable and mineral of that colour.Another page titled “Reds” with a chart various shades with an animal, vegetable and mineral for each.An old book page titled “Yellows” with a chart citing various shades of yellow with an animal, vegetable and mineral of each colour for reference.Another page titled “Greens” with a chart of various shades of green with an animal, vegetable and mineral of each shade.

How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.
