Untangling the tree of life
Just what makes that little old ant… change a flower's nectar content?
Ants play a variety of important roles in many ecosystems. As frequent visitors to flowers, they can benefit plants in their role as pollinators when they forage on sugar-rich nectar. However, a new study ...

Viruses: More survival tricks than previously thought
Among eukaryotes with modified nuclear genetic codes, viruses are unknown. Until now it had been believed that the modifications to the genetic code effectively prevented new viral infections. However, researchers have now ...

Evaluating evolutionary rates could shed light into functions of uncharacterized genes
Genes that have roles in the same biological pathways change their rate of evolution in parallel, a finding that could be used to discover their functions, said a researcher at the University of Pittsburgh School of Medicine ...

'Rhythm' of protein folding encoded in RNA, biologists find
(Phys.org)—Multiple RNA sequences can code for the same amino acid, but differences in their respective "optimality" slow or accelerate protein translation. Stanford biologists find optimal and non-optimal ...

Scientists rise to the challenge of identifying and comparing yeast genomes
If you think yeast is most useful for beer and pizza crust, here's something else to chew on: a team of U.S. researchers has identified and compared the genetic codes for all known species of yeasts closely related to bakers' ...
