Genomics, genetic persistence and the hihi - Genomics Aotearoa

Genomics Aotearoa Aug 20, 2019

Dr Anna Santure, University of Auckland How important is genetic diversity to species persistence? This is a question we’ve been puzzling over in New Zealand, and worldwide, for some decades. It has been difficult to address using ‘traditional’ approaches to determine genetic diversity, which sample just a handful of positions in the genome. However, in recent years, with much lower … Read More

Aotearoa: Land of the long or short chronology - Lost Worlds, Vanished Lives

Guest Author Aug 15, 2019

Lachie Scarsbrook “See the line where the sky meets the sea? It calls me. And no one knows how far it goes”. If you’ve seen Disney’s Moana, like me you probably just sung those first few lines whilst picturing a traditional double-hulled canoe sailing out into the sunny, blue abyss. Discovering new lands: a modern reconstruction of a … Read More

Student evaluations of teaching effectiveness tell us nothing about teaching effectiveness - Physics Stop

Marcus Wilson Aug 12, 2019

I thank my colleague Chris Lusk for bringing this paper by Uttl, White and Gonzalez to my attention. Many universities and polytechnics acquire Student Evaluation data on courses and teacher quality at the end of a course. There are different ways this can be done – here at The University of Waikato students are asked (online) a series of questions … Read More

Quantum cryptography - Physics Stop

Marcus Wilson Jul 30, 2019

I was reading last week a children’s book about “Secret codes”.  You probably know the kind of thing I’m talking about – substituting one letter for another, or a squiggly shape for a letter, rearranging letters, and so on. Fun things to do, but not the basis of modern cryptography. However, the book didn’t just stop at these codes, but … Read More

The complexity of stick insect genomes and why it could help New Zealand conservation - Genomics Aotearoa

Genomics Aotearoa Jul 25, 2019

Dr Ann McCartney We have recently completed the first high-quality genome of a stick insect using link read technology, but what does this mean? And why is a gold standard reference genome important to New Zealand’s conservation efforts? Stick insects are actually biologically interesting. Firstly, in times of stress, they have the ability to become parthenogenic, meaning the females lay … Read More
