This year my husband planted a little patch of glass gem corn (apparently a type of “flint” corn) in our vege garden. We harvested the cobs today, and you can see where the name comes from. I noticed that you could get a good idea of what the main colour of each cob would […]

or, more specifically, a question of lethal allelesA. Lethal alleles were first noticed back in 1905 by Lucien Cuénot, and identified for what they were by Castle & Little in 1910. These two studies, looking at inheritance of yellow coat colour in mice, found that only mice heterozygous for this gene had yellow coats, despite […]
Continue readingYou’ve probably come across the name Kary Mullis recently, via social media. He’s best remembered for his invention (along with a team of other researchers) of the Polymerase Chain Reaction, or PCR for short (and for many biology students was probably immortalised in their memories via this earworm of an advertisement¹). This turned out to […]

You’re probably aware that the Achievement Standards used to assess senior school students’ learning are being reviewed. Science is one of the ‘pilot’ subjects in this process, where a ‘Subject Expert Group’ has developed 4 draft Science standards¹ (a significant step away from the current 30+, and a response to advice from several high-level advisory […]

A couple of days ago newsroom published an article about smallpox, by Farah Hancock. It’s a very good story that covers the nature of smallpox and the history of efforts to develop a […]
Continue readingOver the last few years, OracA has written quite a bit about the so-called 'right to try' legislation that has been enacted in many US states – and, as this post of his describes, will now most likely become a thing at the federal level. (I say "most likely", given President Trump's history of wanting to […]
Continue reading'Raw water' – the latest foolish fad to hit people's screens, pockets, & in some instances I'd guess their toilet paper expenditure as well. I first heard of this particular litre of woo when I read an article in the New York Times with the headline: Unfiltered Fervor: the rush to get off the water […]
Continue readingThe Butchering Art is medical historian Lindsey Fitzharris's first book. And what a book! Descriptions that bring the horrors of pre-anaesthesia, pre-antisepsis surgery shudderingly into view? Very definitely. Science and history? Oh yes, lots of it, and beautifully told. And through it all, the humanity and vision of Joseph Lister and others like him, working to […]

That’s the title of this excellent article by Jennings Brown, and I urge you to go and read the whole thing. It’s the tale of perhaps the last 3 people in the US who are still alive because they are still living in iron lungs. It’s a story of courage and endurance that lets them […]
Continue readingA recent FB post from Stuff discussed the rising concerns around the evolution of antibiotic-resistant bacteria. (This is something that Siouxsie Wiles has often written about: here and here, for example; her excellent book on the subject is reviewed here.) Fairly predictably, it didn't take long for the proponents of essential oils to turn up, soon to be joined by the usual […]
