One of the things that strikes me about the commenters actively opposing vaccinations – e.g. on the many news stories about NZ’s measles outbreak – is their continued readiness to state and repeat mistruths and inaccuracies. You see it all the time, & I have to wonder – is there just this underlying assumption that […]
Continue reading“i’ve done my research!”
New Zealand’s measles outbreak keeps on ticking along. So do the media stories about it. (The FB posts associated with each article aren’t moderated and I suspect this is partly because they generate so many clicks.) A couple of days ago, TVNZ’s Breakfast show carried an interview with a doctor, on the importance of Gardasil, […]
Continue readingwhat happened to the neanderthals?
One of the questions students often ask, when we’re discussing human evolution, is “what happened to the Neanderthals?” After all, this was a large-brained species closely related to our own, with some fairly complex tool technologies and the ability to survive (and thrive) in harsh environmental conditions. Yet they appear to have been replaced by […]
Continue readingmeasles infection & immune amnesia
Measles infection has a couple of longer-term sequelae. One, SSPE, is thankfully rare (although for infants with measles the odds of subsequently developing SSPE are considerably higher than for other age groups). The other, “immune amnesia”, is also strongly associated with having had measles, though this doesn’t stop those opposed to vaccination claiming otherwise. In […]

I’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 readingthe package insert: misunderstood & misrepresented
UNICEF estimates that in the period 2010-2017, 169 million children missed their first dose of the measles vaccine – that’s around 21 million children each year. Sadly, this has simply set the conditions for the measles outbreaks we’re seeing around the world, in high- and low-income countries alike. In the first three months of 2019, […]
Continue readingmeasles infection is not a cure for cancer
I never thought I’d need to write that title for a post. We’re continuing to hear of new measles cases in New Zealand, most recently in this Stuff story about 4 new cases in Auckland (with the possibility that up to 1600 people may have been exposed). One of those ill with the disease is a […]
Continue readingessential oils in the classroom: a rose (or other flowers) would smell as sweet
A story about essential oils being used in classrooms hit the headlines this week. It described how an Auckland primary school had put diffusers into 20 classrooms, using oil blends that would supposedly “stop the spread of viruses and keep children focused at school.” A parent subsequently used the threat of a legal injunction to […]
Continue readingplants, their predators, and early warning systems
People 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 readingthoughts on a question about kākāpō
My 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, […]
