Luciferin, Luciferase, etymology, & innuendo

Alison Campbell • Feb 17, 2021

On Friday (5 February) we went for a walk in the Karangahake Gorge, and were very happy to discover (during the Windows Walk) that there are glow-worms in the darker parts of the mine workings. (Strictly speaking they’re glow-maggots as they’re the larvae of small flies/midges, but that is perhaps less attractive to the ear ) These little … Read More

Vaccines, viruses, & mRNA

Alison Campbell • Dec 13, 2020

Today I was told that the Pfizer-BioNTech vaccine (now approved for use in the US, UK, & Canada) is a virus (screencap at the bottom of this thread). It really isn’t, but I’ve seen this one several times & so I think it’s worth unpacking a little further. (You can also read about mRNA vaccines here, here, & … Read More

Mammoth bones – and … potatoes???

Alison Campbell • Dec 11, 2020

Today I came across an interesting share in a science group that I follow – an article about a “huge 25,000-yr-old hut” made of mammoth bones. Having really enjoyed Jean Auel’s “Earth’s Children” series, of course, I was going to read on. But alas, the article was disappointing: the headline image didn’t match the story; the apparent construction … Read More

Those vaccine ingredients again

Alison Campbell • Dec 11, 2020

A year ago I posted an explanation on vaccine “ingredients”, in relation to some wild claims made about the measles vaccine in the context of Samoa’s measles epidemic. From what I’ve seen on recent RNZ comments threads, an update for the time of SARS-Cov-2 is required. So, here’s purple making a statement about the Pfizer covid-19 vaccine that – … Read More

It always pays to check before you share

Alison Campbell • Nov 19, 2020

Back in 2008, Dr Anthony Fauci (yes, that Dr Fauci) co-authored a paper that examined the interplay between influenza infection and secondary bacterial … Read More

Crabs, carcinisation, and crappy headlines

Alison Campbell • Nov 10, 2020

This is a post of two parts: the interesting tale of convergence involving crab-like creatures, and the very poor – nay, crappy (because I like the alliteration) – headline on a popular article about it. Part 1: the history of carcinization in crustaceans, described in this 2017 paper in the Biological Journal of the Linnean Society (Keiler, Wirkner, & … Read More

First steps: Jerry DeSilva on the evolution of bipedalism

Alison Campbell • Sep 25, 2020

Yesterday morning I got up (at the rather early and unaccustomed hour of 3.30am) to listen to a webinar by paleoanthropologist Dr Jeremy DeSilva¹. Titled “First Steps”, his presentation was about the origins of bipedalism in the human lineage. It was a fascinating session & I thought I’d turn my notes into this post, to share with students, teachers, and … Read More

It’s “only” a 1% death rate

Alison Campbell • Aug 31, 2020

I’m seeing a bit of that phrase in my social media feeds at the moment, in relation to covid-19. In practice, this would mean that if everyone in New Zealand were to catch the virus eventually, that would be 50,000 people dead. The ‘normal’ annual all-cause mortality in this country is around 33,000. It’s been argued that we just … Read More

COVID myths & politics

Alison Campbell • Aug 11, 2020

This year’s election campaign in New Zealand has attracted a number of “fringe” parties, at least some of whose supporters seem to have a fairly tenuous hold on reality and a highly flexible approach to the truth. I mean, how else could one describe some of those affiliated with the NZPP/Advance coalition, whose members & supporters regularly share myths about … Read More

A fishy story: midas cichlids in nicaraguan lakes

Alison Campbell • Jun 11, 2020

Midas cichlids (Amphilophus spp.) are a popular aquarium fish, but in the wild they’re found in South America, ranging from Nicaragua to Costa Rica. The 2018 Schol Bio paper included a really interesting question about a Nicaraguan ‘species complex‘ of these fish, based on a paper in Nature Communications. and a monograph in Cuadernos de Investigacion … Read More
