Exploring the genomic diversity of tubeworm endosymbionts

Tubeworms are cool. (To be read only in your best (eleventh) Doctor Who voice). Although, depending on how close they are to a hydrothermal vent, they might be more on the hot side….Regardless, if you’re on the fence about how … Continue reading

Retrieving a million sequences and avoiding primer bias, a new method that might have it all

We have come a long way since the early days when sequencing was a breakthrough method initially used to identify uncultured microbes from the environment. It is now been almost three decades, in fact, since the first microbial 16S rRNA … Continue reading

Diving deep: Exploring microbial communities under the seafloor

As we all sat staring at three large monitors in the front of the room, the remotely operated vehicle (ROV) Jason hung on to a borehole observatory with one hydraulic arm as the other arm plugged our sampling equipment into … Continue reading

0.80994 leagues under the sea

After a month on the water (and a few weeks getting my land legs again), I’m happily settling back in at home. I just returned from an expedition to a site known as North Pond along the western flank of … Continue reading

Missing symbionts: do some animals lack resident gut microbiomes?

It seems like the field of “gut microbiomics” is having major breakthroughs almost every month these days. It’s very exciting to follow what is being discovered and gut microbes have now been linked with an array of important host traits, … Continue reading

Genomes are coming: Sequence libraries from the honey bee reflect associated microbial diversity

One of the coolest of reasons that cheap sequencing is nifty, in my opinion, is that it has allowed researchers to study individual eukaryotic organisms, and their associated microbes (their microbiome). Let’s be real, we are in the midst of … Continue reading

When less might be more: The evolution of reduced genomes

The advent of affordable genome sequencing has provided us with a wealth of data. Researchers have sequenced everything from Escherichia coli (4.6 Mbp genome size), to sea urchins (810 Mbp), chimpanzees (3.3 Gbp), and humans (3.2 Gbp). Then there are the … Continue reading
