Today is a big day for the genomics of egg-laying animals, with the coordinated publication of three papers on animal sex chromosome evolution and diversity in GigaScience , Nature , and Genome Research by the Qi Zhou lab at Zhejiang University.

With the recent launch of our new GigaByte journal you may have noticed some interesting genome datasets being published, including the banjo frog, common dragonet fish, and extremely rare Nyssa yunnanensis tree. Joining these species on the genomics tree of life this month is a small mouse-like marsupial called the brown antechinus.

GigaScience has spawned a new smaller and more agile sibling: GigaByte, and is the first journal to come from our new GigaScience Press.

As publishers of a lot of plant and animal genomes, the biggest conference for this research community is the appropriately named Plant and Animal Genome Conference (PAG). We’ve attended a number of these giant meetings in their San Diego base, and in recent years they have been branching out to host satellites in Asia (PAG Asia, which last year included a workshop that we participated in). And we attended the 28 ^th edition of the

Regular readers will know GigaScience has published a lot of plant and animal genomes, and the biggest conference for this research community is the appropriately named Plant &

A New High-Quality Reindeer Genome Sequence Provides Resources for Studying Evolution, Domestication, and Adaptation to Arctic Climate. But not the secrets of Christmas. Ewan Birney has previously blogged on the Genome Days of Christmas, but today the full-text version of a particularly Christmassy species has just been published to add to that list.

Deep (ocean) sequencing. Big-(fish) data. The ocean sunfish, must officially be one of the world’s weirdest creatures to enter the “genome club”, and have its genetic code mapped. Laying the most eggs of any other known vertebrate (up to 300,000,000 at a time), and starting out as the size of the head of a pin, sunfish grow to become to largest bony fish in the sea.

The use of “big data” genomics technologies may gather most attention and funding in “big money” settings such as healthcare and agriculture, but due to a precipitous drop in cost its use has become increasingly ubiquitous in all corners of biological research, including biodiversity research and conservation.

Another busy week for the GigaScience team, with the release of a new-look database, more datasets, and a number of talks and announcements at BGI’s annual International Conference of Genomics in Shenzhen.
