This gorgeous little insect is a female Australian bag moth (Cebysa leucotelus) – in this image she’s sitting on the netting we’re using to keep the late-season cabbage butterflies off our brassicas, but I suspect that normally she’d have been a little harder to spot. After all, from the tips of her antennae to the […]

I suspect many of those reading (like many of my friends) will have watched the series The Last of Us. (I haven’t, because I’m fairly sure I’d be spending a fair bit of time with my eyes shut!¹) What you might not realise is that the fungal “protagonist” (for want of a better word) is actually […]
Continue readingpermafrost, viruses, and silly zombie headlines
Permafrost is “any ground that remains completely frozen – 0°C or colder – for at least two years straight”, and as you’d expect is found at high altitudes or in polar regions. It acts like a deep-freezer – scientists have found mammoths buried in permafrost that were so well preserved that at least one field […]
Continue readingmastodons in greenland
What is a mastodon, anyway? Like mammoths (on the left in the image above), mastodons were common during the last ice age, but the two elephant-like creatures are fairly distant relatives. The more-familiar mammoths were close cousins of modern elephants (a fact that is of interest to those considering doing a Jurassic Park on mammoths – […]
Continue readingschol bio exam – a performance standard
This post is intended for students who are preparing for the 2023 Schol Bio exam, and discusses material covered in a tutorial meeting. One of the obvious questions is, what’s the examiner looking for? Like the NCEA subjects. Scholarship subjects all have assessment specifications. You’ll find the Biology one here. The written exam will comprise […]
Continue readingpoor little pangolins – driven to destruction by human greed & stupidity (redux)
When I wrote this, 5 years ago, pangolins were in deep strife due to human greed & stupidity (plus a side order of habitat destruction). I saw this bittersweet video on Twitter today, & thought I’d repost my original article, since nothing has changed.

Continue readingit’s not on to play one discipline off against another
The topic of an ad for a university not that far to the north of where I live popped up in casual conversation today. It was – IMHO – a pretty awful advert, with the implication that science doesn’t change so do an arts degree if you want to think differently. I mean, yuck. But […]
Continue readingnuremberg, & history
There’s a lot been said recently about the Nuremberg code. So what is it, and why is it popping up now? As described in this excellent NEJM article, the Code was developed over 80 years ago in August 1947, by judges involved in the “Doctors Trial” at Nuremberg. There were a total of 13 court trials […]
Continue readingtrends in human evolution – the shoulder
Humans are the only living hominid that can throw objects accurately & at speed – while some of the other great apes can throw objects, their speed & accuracy is not the best. (In his musing on human evolution, Darwin noted that adaptations allowing this would be at a selective advantage as they would increase […]
Continue readingwhat is the “magneto” protein, & why are references to a 2016 paper suddenly in my feed?
A few days back an article in The Guardian popped up in my newsfeed. It was quite old – published in 2016 – but it looked interesting, so I read it & also tracked down the original paper. The article & research paper describe work done to develop and test a potential tool for unpicking […]
