Two species of dung beetles have been released on two New Zealand farms, where the beetles will bury dung that will be broken down by their grubs, earthworms and microorganisms.
New findings from NASA’s Curiosity rover include that only trace amounts of methane exist on Mars, which contradicts earlier observations, and that there is evidence of some Mars meteorites on Earth.
The Department of Conservation will oversee the clean-up of the old mine site at Waiuta, which has extremely high levels of arsenic contamination due to roasting of arsenic-bearing sulfides in the processing of ore for gold.
Scientists have found the biggest single shield volcano on Earth under the north-western Pacific Ocean. They integrated core samples and data from three different research expeditions to confirm the find.
Studies of a well preserved mosasaur fossil found in Jordan have shown that they had tail fins similar to whales and extinct ichthyosaurs. This means they adapted well to their marine environment.
Scientists have written software that uses observations of pulsars to navigate spacecraft travelling in the Solar System and beyond. This is much more accurate than existing navigation methods.
The June 2013 decision by the Hamilton City Council to stop fluoridation of the water supply has been challenged by a referendum in which 70% of voters favour resuming fluoridation.
A biological mechanism used by a native New Zealand soil bacterium to release toxins to kill crop pests like the diamondback moth may be used to generate new insecticides.
The Global Burden of Disease Study has found that mental health and substance abuse disorders are the leading cause of non-fatal illness and the fifth leading contributor to death and disease worldwide.
Cold, oxygen-rich water combined with a methane seep in the seafloor off the North Island have created a unique food web with methane-fuelled bacteria preyed on by thousands of worms, which contribute to the methane release.
A team of mechanical engineering students from the University of Waikato are racing an electric car in the World Solar Challenge in Australia to demonstrate the low environmental impact of the vehicle.
Scientists have worked out how mussels remain attached to various surfaces despite the impact of waves. This knowledge could be used to created better glues and other materials.
Sleep researchers have shown that humans’ biological clocks synchronise to a natural midsummer light-dark cycle when there is no artificial light interference. A typical, modern environment causes a 2-hour delay in the circadian clock.
Inspired by echolocation, researchers developed an algorithm that can reconstruct the 3D geometry of a room from a single sound emission. There are many applications including architectural acoustics and audio forensics.
Researchers used statistical models to analyse how languages change over time. They suggest that seven language families of Eurasia form a linguistic super-family that evolved from a common ancestor language.
Recent research has found that North Island robins have the ability to recognise different people. The finding that there are distinct personalities among bird populations has implications for conservation efforts.
GPS instruments show that, 40 km below Wellington, the Pacific and Australian tectonic plates are slipping past each other. This major seismic event is not felt at the surface.
Hamilton’s public water supply ceased being fluoridated on 21 June 2013. Many of the public submissions to the council were based on inappropriate interpretations of scientific studies, according to some scientists.
The magnitude 6.5 earthquake in Cook Strait in July 2013 struck on a previously unknown fault. Seismologists say an earthquake in that area is not surprising, and aftershocks will continue during the next year.
New Zealand ranks among the five countries with the highest mean expectations for the future in research into optimism. Age was the strongest predictor of optimism.
