What the frac(k) is the problem?
Hydraulic fracturing - a technology commonly known as "fraccing" or "fracking" - widely used in the oil and gas industry overseas has recently triggered some controversy in New Zealand, with critics raising questions over potential environmental impacts.
Though the technology has not long been used in New Zealand, it is expected to be a key part of some future coal seam gas extraction projects, as well as conventional oil and gas extraction.
The technology is already being widely
used across the Tasman - where a similar environmental
debate has been gathering momentum. The SMC went to Australian scientists to get
their views on fracking.
Dr Gavin Mudd, Lecturer in Environmental Engineering, Monash University said fracking had been around for decades in oil and gas industry, but only in the past two decades has it been applied to coal seam gas projects on an increasing scale.
"The process does deserve significant environmental attention due to the potential severity of long-term groundwater impacts. Comparing the impacts entirely depends on what you compare it to - such as normal coal mining and energy production, conventional gas, baseload solar thermal or hydro-electricity," he said.
Local scientists have been cautious in commenting on fracking - its methods and environmental impacts, because those who are knowledgeable on it have close links to the energy industry. The industry itself has been vocal in downplaying concerns over fracking, calling for arguments based on "real evidence".
Fracking is also generating headlines in the US, where a report just released by the Department of Energy claims the environmental impacts of fracking have exaggerated.

Commissioner calls for smarter meters
New Zealand needs to up its game in developing smart meters for use in the electricity industry, according to the Parliamentary Commissioner for the Environment, Dr Jan Wright.
She told the Commerce Select Committee this week that standardization among smart meters was necessary to ensure the industry could in future better manage electricity usage across the country, and prepare for rolling out new technologies such as electric cars.
"My main message is that smart meters don't need to be identical in every respect, but that standardisation of key features is urgently required if we are to achieve a smart grid," Dr Wright told the committee.
Food insecurity concerns grow
The price of milk in New Zealand will be the subject of a Parliamentary Commerce select committee enquiry. The decision comes as debate rages over the rising price of staple food items.
Statistics New Zealand revealed last month that food priced had increased seven per cent in the last year, with a portion of the increase down to the Government's move last October to increase GST from 12.5 to 15 per cent.
The rising costs of basic food staples has been flagged as an arrea of concern by researchers looking at the impact of food insecurity on public health.
Dr Cliona Ni Mhurchu, programme leader in nutrition and physical activity at the Clinical Trials Research Unit of the University of Auckland, said most recent national data (from 2002) showed that food insecurity was an issue for 20-22% of New Zealand households with children, with higher rates among Pacific peoples and Maori.
"While much focus is directed towards tackling problems of obesity and other diet-related non-communicable diseases, there remains a substantial number of people in New Zealand who do not have sufficient nutritious food to eat, and are classified as food insecure."
Her colleague at the University of Auckland, Dr Nikki Turner said inadequate incomes among many families remained the central issue.
"Nutrition has profound effect on the physical, mental and developmental outcome of the child," said Dr Turner, senior lecturer in the Division of General Practice and Primary Health Care at the University of Auckland and health spokesperson for the Child Poverty Action Group.
"A poor diet affects a child's immune system, making them more prone to infections and, paradoxically, obesity, and developmentally makes it harder to concentrate, focus and learn."

number of researchers on food insecurity - you can read it here.
lunacy gets spooned
The media coverage of 'moon man' Ken Ring's theories has been given the dubious honour of the Bent Spoon, the NZ Skeptics Society's award for poor journalism.
The society awarded the Spoon for
"journalistic gullibility" to all news media and
commentators who who took Mr Ring's earthquake prediction
claims at face value.
Ken Rings theories that earthquakes could be predicted by lunar patterns, while completely unscientific, attracted much media attention.
Skeptics NZ media commentator Vicki Hyde said,
"We believe that it is the business of the professional media to ask pertinent questions on behalf of the public when presenting material as factual,"
"Many, many media outlets and journalists failed the basic standards of their profession...they did us all a disservice."
Regarding the moon man media circus, several news personalities were singled out by the society including: Mark Sainsbury (Close Up), John Campbell (Campbell Live), Marcus Lush (Radio Live), Chloe Johnson (Herald on Sunday) and Brian Edwards (Media Blog).
The Skeptics also commended several journalists for critical thinking with their Bravo awards. Bravos went to Janna Sherman (Greymouth Star) for critical coverage of Ken Ring and to Philip Matthews (Marlborough Express) for being direct about the science on 1080 poison.

MS genetics study
offers new leads: A large, international study has
identified many new genetic variations linked to multiple
sclerosis (MS). The study, which included New Zealand
researchers and patients, provides new clues to the
mechanisms underlying this complex neurodegenerative
disorder. Several known genetic factors were confirmed but
new leads were also identified, suggesting novel targets for
skin: An ultra-thin electronic which device attaches to
the skin can be used to measure heart rate and other vital
signs without the bulky electrodes used in current hospital
monitoring. Thinner than a human hair, the device sticks to
the skin relably and contains all the apparatus required to
record and transmit data. The device could also potentially
be used as an electronic bandage to speed up wound healing,
burns and other skin conditions, and it could even provide
touch sense to prosthetic devices such as artificial legs or
Longer working hours
linked to alcohol problems: New research has found that
working at least 50 hours a week increases the risk of
alcohol problems by up to three times.
The New Zealand research used data from the Christchurch Health and Development Study. Data from more than 1000 participants at ages 25 and 30 showed a significant association between longer working hours and alcohol-related problems.
antibiotic resistance in organic poultry farms: A new
study provides data demonstrating that poultry farms that
have transitioned from conventional to organic practices and
ceased using antibiotics have significantly lower levels of
drug-resistant enterococci bacteria. The study is the first
to demonstrate lower levels of drug-resistant bacteria on
newly organic farms and suggests that removing antibiotic
use from poultry farms can result in immediate and
significant reductions in antibiotic resistance for some
