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; […]
Continue readingBack in 2008, Dr Anthony Fauci (yes, that Dr Fauci) co-authored a paper that examined the interplay between influenza infection and secondary bacterial infection in mortality from the “Spanish flu¹” pandemic of 1918-19. He and his colleagues examined tissue samples taken during autopsies at the time of the pandemic, using their findings plus notes taken during […]
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 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 […]
Continue readingI’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 […]
Continue readingThis 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 & […]
Continue readingMidas 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 […]
Continue readingThe 2015 Schol Bio paper included a question about a group of birds known as honeycreepers, specifically, the 56 species endemic to the Hawaiian islands. (Or, were endemic: 18, or perhaps 19, are still living; the others are extinct.) Students who’ve already had a look at this paper as part of their preparation for the exam will […]
