Genes responsible for red coloration in birds found

An international team of researchers has found the genes responsible for converting yellow carotenoids in birds to red ketocarotenoids. In their paper published in the journal Cell Biology, the group describes the steps they ...

Dinosaur faces and feet may have popped with color

Most birds aren't as colorful as parrots or peacocks. But if you look beyond the feathers, bright colors on birds aren't hard to find: Think pink pigeon feet, red rooster combs and yellow pelican pouches.

Why some of Darwin's finch nestlings have yellow beaks

Carotenoids are the underlying pigment for much of the enormous variety of color found across birds and form the basis for the colors red, yellow and orange. In a study published in Current Biology, researchers from Uppsala ...

Tweaking carotenoid genes helps tomatoes bring their A-game

Cooked, fresh, sun-dried, or juiced, whichever way you prefer them, tomatoes are arguably one of the most versatile fruits on the planet—and yes, despite mainly being used in savory dishes, tomatoes really are a fruit.

How boundaries become bridges in evolution

There's a paradox within the theory of evolution: The life forms that exist today are here because they were able to change when past environments disappeared. Yet, organisms evolve to fit into specific environmental niches.

Shedding light on the brown color of algae

For many people, algae are just an odorous nuisance on their vacation beach or unwelcome guests in the garden pond and aquarium. This does not take into account, however, the enormous effects these mostly microscopic aquatic ...

Better anchor roots help crops grow in poor soils

A metabolite in plants that regulates the growth of anchor roots—vital for sustaining water and nutrient uptake in plants—has been identified and may have useful applications in agriculture.

How plants expand their capacity to use solar energy

Green plants capture light that spans the visible solar spectrum, and while a broad spectral range is required for sufficient absorption, the process requires energy to be funneled rapidly and efficiently downhill to drive ...
