Plague enthusiasts: do they assume no-one checks?

Alison Campbell Jul 19, 2019

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, and I have to wonder – is there just this underlying assumption that no-one will actually check? … Read More

What happened to the Neanderthals?

Alison Campbell Jun 12, 2019

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 Yet they appear to have been replaced by anatomically-modern humans (in Europe, anyway) … Read More

Measles infection and immune amnesia

Alison Campbell Jun 04, 2019

Measles infection has a couple of longer-term sequelae.

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, more than 110,000 measles … Read More

Measles infection is not a cure for cancer

Alison Campbell Apr 30, 2019

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 10-month-old child, too young to have received her first dose of the MMR vaccine. Completely predictably, … Read More

Essential oils in the classroom: a rose (or other flowers) would smell as sweet

Alison Campbell Apr 08, 2019

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 stop this practice, at … Read More
