Scientists sequence world’s largest pangenome to help unlock genetic mysteries behind finer silk

Silk worms

BGI Genomics, in collaboration with Southwest University, the State Key Laboratory of Silkworm Genome Biology, and other partners, has constructed a high-resolution pangenome dataset representing almost the entire genomic content in a silkworm. Previously, due to the scarcity of wild silkworms and technical limitations of former studies, many trait-associated sites were missing. This is the first research ever to digitize ...

Astronomers Detect Protective Shield Defending Pair of ‘Dwarf Galaxies’ with help of FUSE, Hubble

For billions of years, the Milky Way’s largest satellite galaxies – the Large and Small Magellanic Clouds – have followed a perilous journey. Orbiting one another as they are pulled in toward our home galaxy, they have begun to unravel, leaving behind trails of gaseous debris. And yet – to the puzzlement of astronomers – these dwarf galaxies remain intact, with ongoing vigorous star ...
