Featured image from https://www.environment.nsw.gov.au/topics/animals-and-plants/native-animals/native-animal-facts/brush-tailed-possum Recently I shared this Spinoff article about extinction on Twitter, & tagged the Science Learning Hub as the NZ focus makes the article a good fit with their mahi supporting student learning. But I was somewhat surprised to have someone else pop up saying that they wouldn’t read it because, […]
Continue readingI 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 readingImage from Science News, courtesy S.Mitoh Autotomy. There’s a word you don’t see every day – but those familiar with lizards may well have seen the result. For autotomy is the scientific name for what I suppose we could also call “self-amputation”: the process whereby an animal deliberately sheds a part of its body (a […]
Continue readingI wrote this post a couple of years ago, but I think it’s worth revisiting it. Why? Because these crayfish are in the news again – apparently they’ve “taken over” a Belgian cemetery (or, more correctly, the waterways in that cemetery). Local scientists believe that someone must have had the crustaceans in a home aquarium […]
Continue readingn July this year, the Seattle Times ran a story on an orca called Tahlequah – she was pregnant, again. And just yesterday, she gave birth. The story is particularly noteworthy because a couple of years ago, Tahlequah also bore a calf, which died, and she then carried the dead baby on her nose for […]

(They’re not an isolated example; a range of parasites change their hosts’ behaviour. See here and here for example – though as you’ll find, […]
Continue readingI’ve learned quite a bit about spiders over the years. (And I have never been able to understand the “burn it with fire!” some folks take towards these 8-legged creatures.) For example, it turns out that some spiders actively hunt fish, while others are vegetarian! Then, late last year, I came across a couple of […]
Continue readingPeople tend to think that plants don’t do much from day to day – certainly when I asked my first-year students at the start of the course, they were far more interested in animals than in plants. Poor plants! But then, to the casual eye I guess they’re fairly static creatures 🙂 However, it turns […]
Continue readingMy interest in kākāpō way back in my honours year at uni: a guest speaker told us that as far as anybody knew, the last remaining birds were a few males, somewhere in Fiordland. I remember feeling that that sounded really sad – those lonely males booming for females who never came. Shortly after that, […]
Continue readingA substantial proportion of the CO2 we release into the atmosphere, via burning fossil fuels, ends up dissolved in the ocean. The impact of this is a change in the ocean’s acidity: the pH drops. According to the Smithsonian, oceans have become substantially more acidic over the last 200 years (the period of the Industrial […]
