The totality of bacteria, viruses and fungi that exist in and on a multicellular organism forms its natural microbiome. The interactions between the body and these microorganisms significantly influence the host organism's functions and health. Among other things, researchers have shown that the microbiome plays an important role in defense against pathogens.

On the other hand, they suspect that imbalances in the microbiome's composition are linked to the development of so-called environmental diseases, such as chronic inflammation.

Predicting jumping genes' roles in changing genome size

A genome contains all of the DNA of every living organism, but its contents don't stop there—most of these structures also contain snippets of DNA that can copy and paste themselves to "infect" a genome, expanding its size. Precisely why that happens remains a mystery.

The FDA wants to pull its approval of a drug. It’s not so easy.

In May 2021, the US Food and Drug Administration released a lengthy briefing document on an experimental medication for a rare autoimmune form of vasculitis that often damages the kidneys and lungs. The agency was on the fence about whether to approve the treatment, and it wanted
