Research brings swine industry closer to broad virus protection

After eight years of gathering data from more than 1,000 pigs infected with porcine circovirus 2, University of Nebraska–Lincoln researchers have identified the gene associated with pigs' susceptibility to the deadly swine ...

Plant characteristics shaped by parental conflict

Different subpopulations of a plant species can have distinct traits, varying in size, seed count, coloration, and so on. The primary source of this variation is genes: different versions of a gene can lead to different traits. ...

How to make fish shine

Scientists from the University of Bath have helped to figure out why shoals of fish flash silver as they twist through the water by studying how the shiny silver cells are created in zebrafish.

Why huskies have blue eyes

DNA testing of more than 6,000 dogs has revealed that a duplication on canine chromosome 18 is strongly associated with blue eyes in Siberian Huskies, according to a study published October 4, 2018, in the open-access journal ...

Common genetic toolkit shapes horns in scarab beetles

Horns have evolved independently multiple times in scarab beetles, but distantly related species have made use of the same genetic toolkit to grow these prominent structures, according to a study publishing October 4, 2018 ...

In a tiny worm, a close-up view of where genes are working

Scientists have long prized the roundworm Caenorhabditis elegans as a model for studying the biology of multicellular organisms. The millimeter-long worms are easy to grow in the lab and manipulate genetically, and have only ...

What's all the 'excitement' about flight?

Have you ever wondered how tirelessly the tiny fruit fly buzzes around your fruit bowl? This behavior not only demands tremendous energy but also requires highly coordinated neuronal signaling that enables continuous flight. ...

How do fruit flies grow legs? Solving a molecular mystery

What do cancer and the growing legs of a fruit fly have in common? They can both be influenced by a single molecule, a protein that tends to call the shots inside of embryos as they develop into living, breathing animals. ...
