March of the mammoths Improvements in our genetic tinkering capabilities have led several people to suggest potential uses for our newfound powers. Although we ought to add some nuance and note that those powers are still in development. In any case, one of those powers is quite impressive. De-extinction, or the process of bringing back […]...

The real cost of sequencing is as hard to pin down as a sumo wrestler.

Practically all Blastocystis research has focussed on identifying a role for the parasite in disease. Meanwhile, no one has really tried to looked into what Blastocystis may tell us about human health. Together with partner labs, our lab has produced data suggesting that Blastocystis carriage is extremely common, and probably also extremely long lasting. We have also shown that the parasite is associated with certain gut microbial communities and that it is more common in healthy individuals tha........ Read more »

Metagenomic profiling, also called metagenomic shotgun sequencing (MSS) represents a powerful application made possible by the digital nature of next-gen sequencing technologies. In it, one basically sequences a sample isolate obtained from somewhere — a shovelful of dirt, a scoop of plankton, or anything else that contains living organisms. MSS has proven particularly useful to […]... Read more »

A significant fraction of the functional variation in humans lies outside of known protein-coding regions. We all know that. Yet every individual’s genome harbors millions of noncoding variants, most of which are likely neutral with respect to phenotypes. Identifying the subset of noncoding variants that are functional remains notoriously difficult, and represents a considerable scientific challenge we face as […]... Read more »
