Chatham Islanders could be forgiven for believing they are living largely alone, in the most easterly part of New Zealand, more than 800km from the South Island. But some visitors will be arriving there next week — a high-powered team of science outreach educators from the Otago Museum and University of Otago.
The "mini-expedition" will include museum director, physicist and astronomer Dr Ian Griffin, Dodd-Walls Centre for Photonics and Quantum Technologies director Prof David Hutchinson and museum science presentation co-ordinator Amadeo Enriquez-Ballestero. They will fly to the remote islands from Wellington on Monday and return late next week.
Prof Hutchinson and Mr Enriquez-Ballestero said they were excited about undertaking the "Extreme Science" project trip, backed by the Ministry of Business, Innovation and Employment’s Unlocking Curious Minds funding. They aimed to inspire young school pupils on the Chathams with what science and technology could already tell them about their world, and potential employment prospects. Museum science engagement director Dr Craig Grant said he also hoped the wider Chathams community "might see how new technologies can help offset some of the challenges of their remoteness, and enable them to take advantage of their unique location", such as linking the science of astronomy with night sky watching and "astrophotography" tourism.
Prof Hutchinson, of Otago University, stressed the expedition aimed "to build a relationship", and the funding included support for one of the teachers on the Chathams "to visit us back here at the university".
A telescope and seismometer would be taken to the Chathams and left behind with other science equipment. The legacy was important, he said. The team viewed this "as the start of a long relationship, not a one-off visit that is then forgotten".

Time stretch and its applications
02 June 2017
Observing non-repetitive and statistically rare signals that occur on short timescales requires fast real-time measurements that exceed the speed, precision and record length of conventional digitizers. DWC Principal Investigator Neil Broderick and collaborators have written a paper on Time Stretch and its applications in Nature Photonics (in PDF format).

View the DWC Interface Challenge video.
The Dodd-Walls Centre and the MacDiarmid Institute connected their top scientists with some of New Zealand’s most innovative companies to showcase what they could do for them. The Interface Industry Challenge was launched late last year asking companies to come up with commercial problems they couldn't solve within their own technological capability, which the Centres of Research Excellence (CoREs) would help solve for free.
The CoREs are virtual institutions that draw on the talent of top scientists from anywhere in the country in a particular research area. The Dodd-Walls Centre specialises in photonic and quantum technologies while the MacDiarmid Institute focuses on materials science and nanotechnology. Having signed non-disclosure agreements, the two CoREs are working on proofs of concept to solve problems for seven companies they’ve matched to various scientists. The scientists are now starting to produce some solutions the companies can use as a competitive advantage, and in some cases may even lead to new intellectual property.
The directors of both institutes, Professor David Hutchinson from the DWC and MacDiarmid’s Professor Thomas Nann say New Zealand industry needs to keep innovating to stay ahead. The challenge was a fun way of letting companies know what scientific help they could tap into, and both CoREs hope funding the initial research now will benefit them with longer-term research partnerships. The seven companies involved range from larger companies such as Fisher & Paykel Healthcare and Buckley Systems to start-ups Avertana, Lanaco, Aquafortus Technologies and Invisi Shield.
Andy West, a director on the boards of Aquafortus and Lanaco, says it is unusual to get free research from CoREs and that’s helpful for both companies he's helping govern which are still at the stage of “burning capital and are yet to enter full revenue profitability,” although Lanaco is close. Lanaco is a materials science company that uses fine wood blended with synthetic fibres to produce what it dubs as the world's most breathable air filter, while Aquafortus Technologies is developing water extraction technology involving organic chemistry which could potentially extract water from liquid waste materials and help desalination. “We have access to some extremely clever people across a range of universities as CoREs are not normally in just one site – they draw the best people from around the country in any given field. And we have access to really expensive scientific equipment we couldn’t afford ourselves,“ Dr West says.

Extreme hydrothermal conditions at an active plate-bounding fault; DWC Investigator, Professor Neil Broderick, is among a group of scientists who have recently had their paper published in "Nature".
Extremely high temperatures and fluid pressures have been measured in a borehole in the Alpine Fault in New Zealand, a Nature paper reports. The fault is expected to rupture in a magnitude-8 earthquake in the next few decades and the study could have broad implications for understanding earthquakes and fault zone geology.
The Alpine Fault is a major plate boundary fault that runs most of the length of New Zealand’s South Island. The fault produces large earthquakes approximately every 300 years, and it last ruptured in 1717. Rupert Sutherland and colleagues drilled a scientific borehole into the fault to examine the hydrothermal conditions therein.
They collected comprehensive rock, mud and seismological observations and found that temperatures and fluid pressures in the borehole were much higher than expected, particularly in the ‘hanging wall’ above the fault, where the average temperature gradient reached around 125 degrees Celsius per kilometre of depth. Values above 80 degrees Celsius per kilometre tend to be associated with volcanic regions, but there is no evidence for volcanism near this site. The authors conclude that these extreme hydrothermal conditions result from rapid fault movement, which transports rock and heat from greater depths, and fluid movement through fractured rocks, which concentrates heat into valleys.

DWC Investigator Dr Maarten Hoogerland was a contributing author of the following article recently published in Optica.
Large-scale quantum networks could allow a wide variety of applications in quantum computing and simulation. We have demonstrated the operation of a single node for use in such a network. A fiber ring cavity contains a nanofiber section, which mediates atom–light interactions through the evanescent field. We observe collective enhancement of the coupling rate between the ensemble of atoms and the light in the fiber.
This work, published in “Optica”, represents an important step toward implementing such a large-scale all-fiber quantum network.

The equipment Dr Mikkel Andersen and fellow researchers have developed to control individual atoms looks like the stuff of historic science fiction. There are seven lasers and a host of other scientific apparatus in a large machine, and when one researcher let a wire fall in front of a powerful laser it promptly began to smoke in a slightly alarming manner. But the equipment in a lab in a University of Otago science block has helped Dr Andersen and his team do what has not been done before; control individual atoms, making them appear wherever they want them to.

New gas sensing using photonic technology
13 February 2017
Dunedin-based Photonic Innovations has acquired complementary gas detection technology that makes workplaces such as meat processing companies and cool stores safer. The technology was acquired from Auckland company Southern Photonics. Both companies use lasers for detecting gases instead of chemical sensors, which were part of the safety problem at Pike River mine. Photonic Innovation chief executive Dr Ojas Mahapatra said lasers are more reliable and cheaper to operate.

Otago Museum to celebrate Women and Girls in Science
9 February 2017
To celebrate the annual United Nations International Day of Women and Girls in Science, Otago Museum, in collaboration with the Dodd Walls Centre of Research Excellence, is hosting a group of Year 11 Otago students this Friday 10 February for a behind-the-scene visit at the Museum. The student’s tour will include a visit to the Museum’s Collection and Conservation labs, Discovery World Tropical Forest, and will finish with a Women in Science panel discussion and question and answer session.
The panel will consist of female staff members from both the Museum and the University of Otago who trained in science and are now involved in a wide range of activities, from researching climate change in Antarctica, to taxidermy, to caring for thousands of butterflies in Australasia’s only three-level live butterfly house. This includes Bianca Sawyer (Physics), Alison Heather (Physiology), Lisa Craw (Geology) and Nysa Mildwaters (Otago Museum).
Nathalie Wierdak, Otago Museum Outreach Coordinator, is pleased that the Museum and the Dodd Wall Centre are be able to offer this event to female students in the region. “This week’s event is an exciting one – not only does it mark a significant date in our science calendar, it once again highlights the importance of encouraging females of all ages to pursue a career in science,” says Wierdak.
