Recent research published in Nature Climate Change has found that reef fish can inherit from their parents the genetic tools to adjust to warming oceans. Obviously, given that our climate is rapidly changing, the decline of animal populations – particularly marine populations – is a distinct concern. For the first time, researchers from the ARC Centre of Excellence for Coral … Read More

When I was a child, I was rather prone to misbehaving. On occasions when I was particularly naughty, my father would sit me down with a copy of the Encyclopaedia Britannica, and would order me to rewrite four of my favourite entries. It wasn’t actually that bad a punishment; being rather childish and petulant, … Read More

Fecal microorganism transplant (FMT) is a process wherein fecal matter (aka poo) is collected from a tested donor, mixed with a saline solution, strained, and reintroduced to a patient, … Read More

Students often get to look at hydras – tiny, fresh-water members of the group that includes sea anemones, jellyfish, corals, and the Portuguese man’o’war. All these cnidarians have a simple body-plan: two layers of true tissue with a jelly-like layer between them, a sac-like gut with a single opening that acts as both mouth and anus, and the characteristic stinging cells – … Read More
