Image from Pixabay, via photosforclass.com A couple of days ago TVNZ rather credulously carried a story under the headline that “garlic can help” cure flu or covid-19, seemingly based on this article in the Financial Review. Presumably with the added benefit of keeping vampires away. However… from the Financial Review piece That is, the TVNZ headline […]
Continue readingPermafrost 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 readingJust this morning a journalist sent me a link to a press release about a new paper looking at how SARS-Cov-2 affects the vascular system, & asked me to comment on it for a article. If you’d like to read the actual paper you can find it here, but be aware that it does get […]
Continue readingRecently I was told I needed to go to the Youtube channel of Dr Sam BaileyA and watch one of her videosB. So I did. This particular video is called The Truth About Virus Isolation, and yes it’s on Youtube, and no I’m not linking directly because I refuse to link to such a misleading […]

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 readingThis 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 […]
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 readingThis 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 […]
Continue readingFor the last few years it’s been pretty much received wisdom that African populations shared only a tiny proportion of their genes, if any, with Neanderthals. In contrast, other non-African sapiens populations had a small but significant admixture of Neanderthal genes. The underlying reason for this, it’s been assumed, is that Homo sapiens and neandertalensis only bred with […]
