You’ve probably seen forensic scientists on TV taking swabs and fingerprints from crime scenes. They aren’t wearing labcoats, hairnets and gloves to look cool but to prevent them contaminating their forensic evidence with their own DNA. But how do scientists deal with items that are already contaminated with unwanted human
The shift from hunting and gathering to cultivating crops and livestock was one of the most important developments in human history. But despite its significance, many questions still remain about how crops were first domesticated. One much debated question has been at what point during domestication is genetic diversity lost?
Karaka, with its large shiny leaves and bright orange fruit, is one of New Zealand’s most distinctive trees. But in pre-European New Zealand, karaka was much more than just a handsome tree – the kernels of its fruit provided an important food source for Māori. This was despite the poisonous
New Zealand has a new species of seabird. Te Papa scientists recently described Imber’s petrel (Pterodroma imberi) from the Chatham Islands as a new species. A previous study that measured a large number of seabird bones from the Chatham Islands found three size categories. The largest bones belong to
Last week I performed the first DNA extraction in Te Papa’s brand new genetics laboratory. Our lab is the first genetics lab in a New Zealand museum and will allow Te Papa scientists to analyse the DNA of our unique plants and animals. Genetic information is increasingly being used to examine the
A new paper by Te Papa researchers and their colleagues from Massey University, NIWA and the Swedish Museum of Natural History, describes not one but THREE new species of hagfish. This increases the total number species found in New Zealand waters to eight. What are hagfish? These strange creatures, also
Citizen science is all the rage right now in New Zealand, especially given its emphasis in the National Science Challenges and Science and Society project. Getting the public participating in science experiments is seen as a way to get them engaged in science. Te Papa is currently running its own
