DNA shows tiny tardigrades are just as cool as we thought - News

Jean Balchin Jul 28, 2017

New genome sequences have revealed exciting new information about the origins of tardigrades as well as the genes that underlie their extraordinary ability to survive in extreme conditions.  A team of researchers led by Mark Blaxter and Kazuharu Arakawa from the universities of Edinburgh, Scotland and Keio, Japan respectively, have carefully stitched together the DNA code for two … Read More

Five things you should know about taxonomy - Guest Work

Guest Work Jul 10, 2017

Kevin Thiele, University of Western Australia; David Yeates, CSIRO; Kym Abrams, University of Western Australia, and Nerida Wilson, Western Australian Museum Earlier this year, a Canadian scientist named a new moth species Neopalpa donaldtrumpi (read that name out loud for full effect). It’s an insect with a golden hairdo and relatively … Read More

Unravelling the twisted story of DNA - A History of NZ Science in 25 Objects

Jean Balchin Jun 28, 2017

This grainy, black and white photograph is quite possibly the most important photograph in human history. Photograph 51, the unimaginatively-named X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a PhD student under the supervision of Rosalind Franklin at King’s College London. Photograph 51 triggered the development … Read More

Ancient rat dung a window into the past - News

John Kerr Nov 03, 2016

The bits of plant and animal matter found in fossilised rat poo can tell us a rich and detailed story of New Zealand’s past. Rat droppings are something most people actively avoid, but not Associate Professor Janet Wilmshurst. She has just been awarded a $830,000 grant from the Marsden Fund to take a closer look at preserved … Read More

Why isn’t there a gene for depression? - Guest Work

Guest Work Sep 14, 2016

Sarah Bailey, University of Bath Depression is sometimes categorised as a mental, rather than a physical illness – as though somehow mental health is different from physical health. But the brain is not a magical black box inside your head. It is an organ, just like the heart or lungs, made up of cells and supplied with … Read More

23 and NZ: Genetic testing results restricted - The Dismal Science

Eric Crampton Sep 06, 2016

I knew that genetic testing service 23andMe was having FDA trouble in the US: the FDA restricted 23andMe from providing health advice based on its genetic tests except where the FDA approved the specific tests. As Gizmodo put it, you’re getting less service for more money, but with an FDA seal of approval on those tests you … Read More

Ice ages led to ‘explosive’ diversity in Kiwi species - News

John Kerr Sep 01, 2016

Ancient walls of ice separating kiwi populations have left their mark in the DNA of New Zealand’s most iconic species. A new study published this week in PNAS has revealed the enormous impact historic cold snaps had on the evolution of kiwis. Researchers based in Canada, in collaboration with Department of Conservation scientists, examined a database of kiwi DNA across the geographic … Read More

Can genes really predict educational achievement? - Guest Work

Guest Work Jul 27, 2016

Daphne Martschenko, University of Cambridge Researchers at King’s College London say they are able to predict educational achievement from DNA alone. Using a new type of analysis called a “genome-wide polygenic score”, or GPS, they analysed DNA samples from 3,497 people in the ongoing Twins Early Development Study. They found that people whose DNA had … Read More

The Earth’s biodiversity could be much greater than we thought - Guest Work

Guest Work Jun 30, 2016

By Mike Lee, Flinders University and Paul Oliver, Australian National University After centuries of study, you’d think we’d have at least a rough idea of how many different species of life exist on Earth. This is becoming even more pressing as biodiversity disappears at an increasing pace due to human impacts. Some species are going … Read More
