NIWA climate record stands - High Court
The High Court of New Zealand has backed the science behind NIWA's temperature data, rejecting claims in a legal challenge brought against them.

In 2010 the New Zealand Climate Science Education Trust applied to the high court for a judicial review of the National Institute of Water and Atmospheric Research (NIWA)'s actions in publishing its national temperature record, claiming that adjustments in the data used led to an artificial increase of 1 deg C warming between 1909 and 2008.
Justice Geoffrey Venning, in a High Court ruling released today, rejected the Coalition's challenge of the official NIWA temperature record:

"The plaintiff alleges that by departing from recognised scientific opinion NIWA breached its statutory obligations, including its obligation to pursue excellence. I am satisfied on the evidence that NIWA applied credible scientific methodology and, as such, did not breach any obligation it may have had to pursue excellence."

"The plaintiff does not succeed on any of its challenges to the three decisions of NIWA in issue. The application for judicial review is dismissed and judgment entered for the defendant."

In a media statement responding to the ruling - endorsed by a number of leading climate scientists - Prof James Renwick of Victoria University said:

"Scientific analysis and discussion is carried out through the peer-reviewed literature. The basic science of climate change (global warming) has been established for well over a century, and almost all scientists active in climate research agree that human activity is causing the climate to change. For a small group of scientists to appeal to a court of law to find otherwise is bizarre."

Justice Venning also awarded legal costs to NIWA - which Prof Renwick said were estimated at at well over $100,000.

Ag-biotech future in spotlight
Agricultural Biotechnology International Conference (ABIC 2012) wrapped up in Rotorua this week, with headline appearances by scientists from some of the biggest global players in the industry.

The conference brought together international visiting speakers and local experts to provide insight into the latest advances in agbiotech and discuss how technologies can be applied to global issues such as climate change, sustainability, food production, energy, health and nutrition.

The Science Media Centre hosted a briefing with a panel of ABIC speakers on the topic of food security. You can play back a full recording of the media briefing on our website.

Prof Robert Reiter, a molecular biologist and VP Biotechnology at Monsanto, whose presence attracted substantial reaction from protesters and garnered significant attention in media coverage of the conference, led off his plenary session with images of blasted corn from the severe drought currently hammering US farmers, making a direct link to climate change impacts and the challenges of planning now for more extreme conditions in future.

Conventional crop breeding requires a 7 - 8 year cycle, compared to 10 - 15 years from inception to development for genetically modified crops. Both require an ability to accurately anticipate future needs, and incorporating climate change impacts is now a key part of that for the big industrial players.

In response to this, Monsanto is preparing to launch a drought-resistant hybrid corn, which will be the first of a new class of biotech products. To date, Dr Reiter said, GM crops from the company have targeted single traits -- like insect or herbicide resistance - an approach that only requires the plant to express a single new protein to be effective. By contrast, engineering for drought tolerance involves a complex interaction of genes - over 30,000 genes in corn - which makes the process enormously more difficult and time consuming.

Pesticide resistance is a growing problem, one that Monsanto acknowledges, with more weeds every year developing a tolerance for formerly unsurvivable herbicides like glyphosate (a.k.a. RoundUp). New technologies in the pipeline highlighted the increasingly intensive escalations underway in the inexorable arms race between farmers' crops and resistant weeds.

One response from Monsanto involves stacking resistance to multiple herbicides in the next rollout of GM crops, enabling these crops to survive when farmers dose resistant weeds with a new cocktail of chemicals -- an approach that seems a stop-gap measure at best.

A second, more experimental approach -- still in early stages of development -- Reiter termed "agbiologicals", a new class of topical sprays that contain RNA targeted to specific resistant weed varieties and other pests. Intriguingly, the RNA sprays will also be able to fight off viral infections in crops, something outside the scope of conventional agricultural sprays. Sprayed plants will absorb the RNA and with it the ability to express new proteins, without altering their own genes. According to Reiter, the sprays will have a temporary effect, lasting as long as it takes for the RNA molecules to degrade.

Golden bananas

In a shift away from the focus on big industry players, Professor James Dale from Queensland University of Technology honed in on the issue of using genetic engineering to combat malnutrition and poverty -- a selling point heavily emphasised by boosters of the technology. Prof Dale called attention to the scarcity of essential nutrients like iron and vitamin A in the world's staple crops, and highlighted global efforts to change this through fortification of the plants themselves. The most famous example is Golden Rice, a rice variety genetically modified to be rich in beta carotene, widely touted for its potential to save lives and prevent blindness in SE Asia, but mired in prolonged regulatory battles that have prevented its release since its development nearly 15 years ago.

Much of the world's poor survive on less well-known staple crops, like millet, cassava and sorghum. Dale's group have won funding from the Bill & Melinda Gates Foundation to work on bananas, which provide the main source of dietary starch for large populations in sub-Saharan Africa. Unlike the dessert varieties sold in the West, these are cooking bananas, selected from wild-growing varieties and never targeted by breeding programmes for improvement. Although they are often the only food source for people who rely on them, with an average consumption of over half a kilo of bananas a day, they are relatively deficient in key vitamins and minerals.

Dale's team, working in parallel with scientists in Uganda, are developing an orange-fleshed cooking banana rich in vitamin A, by inserting a gene derived from a Papua New Guinea wild banana variety that is high in beta carotene. Queensland regulators fast-tracked the project to allow it to go straight from the lab to field trials, and the most promising genes are already being reproduced by local scientists in field trials of Ugandan bananas.
Plain branding stubs out appeal
A new international study has added weight to literature showing plain packaging of cigarettes reduces appeal - and highlighted the contentious policy discussions currently underway in New Zealand.

The research, published in BMC Public Health this week found that removal of all description from the packs, leaving only the brand, led to a sample of 640 Brazilian females rating the packs significantly less appealing. When offered a (hypothetical) free gift participants were three times more likely to choose a branded pack then plain packaging.

The results from this study, the first to look at the effect of plain cigarette packaging on smoking in Latin America, backs up a wealth of similar research carried out in other countries (including New Zealand), which has found that plain packaging makes cigarettes less appealing to young people.

Professor Alistair Woodward, Head of School of Population Health, University of Auckland, commented:

"The findings from the Brazil study fit with what has been observed elsewhere. Tobacco packaging affects the opinions and behaviours of smokers. Many controlled studies of the kind carried out in Brazil have demonstrated this. The tobacco industry knows very well the value of brand packaging. This is why they have invested so heavily in design and illustration in the past, and why the industry now opposes plain packaging so vehemently."

Also commenting on the research was Canterbury economist and SciBlogger Dr Eric Crampton. He pointed out that as plain packaging has not been implemented anywhere, we have no robust evidence of its effects. He suggests a controlled trial of policy,

"If we cared about knowing whether tobacco plain packaging has any effect, we could find out pretty easily. Set the whole thing up as a randomized policy trial. Some parts of the country get plain packs, some parts don't, and watch what happens over the subsequent few years."

You can read more expert commentary on the SMC website.

Quoted: New Zealand Herald

"The gene modification industry does its case no favours with apocalyptic predictions of population growth and food shortages. It is enough that genetics can increase crop yields, reduce the need for insecticides and make farming more profitable.

"A nation that depends crucially on farm exports and needs to keep up with all advances in the field, cannot close its mind on this subject forever. It is time for a rethink".

Research highlights

Please note: hyperlinks point, where possible, to the relevant abstract or paper.

Bottom trawling 'ploughing' the sea floor: The practice of bottom trawling in the fishing industry is drastically changing the shape of the sea floor, according to new research. US scientists have documented the remarkable 'smoothing' impact of trawling on the submarine landscape, noting the changes could impact ecosystems adapted to live in the rough and ragged submarine terrain. While drawing data from a US example, the authors point out that that New Zealand is among the world's bottom trawling hotspots.
Nature

Spinach biohybrid cells: Researchers have taken a page from Popeye's book and harnessed the power of spinach. They have developed a 'biohybrid' solar cell which uses photosystem-1, a photosynthetic protein extracted from spinach, and doesn't require rare and expensive materials like platinum or indium. The researchers believe that, with further development, the cells could be an effective competitors in solar energy generation within three years.
Advanced Materials

Slowing down time: Professional ball game players report the feeling of the ball 'slowing-down' just before they hit it. Confirming these anecdotal comments, a new study shows that time is perceived to slow down during the period of action preparation. The authors suggests that the slowing down of subjective flow of time during action preparation is due to the increased intake of sensory information just before executing an action.
Proceedings of the Royal Society B: Biological Sciences

War changes the brain: A before and after brain scanning study of soldiers serving in Afghanistan revealed that exposure to combat stress, such as armed combat, enemy fire, combat patrols, asymmetric warfare, and improvised explosive device blasts, affected the structural integrity of the midbrain, negatively influenced its activity, and interfered with the soldiers' ability for sustained attention during cognitively exacting tasks.
