WCSJ 2011

The World Conference of Science Journalists wrapped up this week in Doha, Qatar.

The gathering offered a chance for established Science Media Centres (from Japan, Australia, Canada, the UK, Denmark and NZ) meet and discuss the expanding network. Interest in the SMC model is now emerging in China, Norway, Italy, Germany and Nigeria

The SMCs also presented a panel on their role during the Fukushima nuclear crisis, and debated the value of experts put forward -- did nuclear scientists 'play down' the threat, and did their contributions help or hinder journalists?

Peter Griffin has been present at the proceedings and sent this post on public sector scientists being discouraged or even banned from discussing science-related issues in the media.

Phenazepam halts Pineapple Express

Yesterday the Ministry of Health announced a recall of a popular brand of 'synthetic cannabis' after it was discovered that the smoking mixture contained a prescription sedative.

Testing by Environmental Science and Research (ESR) detected the prescription drug phenazepam, in a sample of Kronic - Pineapple Express.

Phenazepam is a benzodiazpeine, belonging to the same class of anti-anxiety pharmaceuticals as drugs like Valium and Xanax. Originally developed in the USSR, phenazepam is not widely used clinically but has been known to be recreationally abused.

The brand found to contain phenazepam, Kronic, is just one of many varities of herbal smoking blends treated with legal, psychoactive synthetic cannabinoids. These 'legal highs' have been causing public debate over their effects, safety and accessibility.

The revelation that the Pineapple Express variety contained phenazepam has complicated the debate further. Speaking to the Science Media Centre, Dr Keith Bedford, Forensic Manager at ESR, said:

"My suspicion is that phenazepam is contributing to the effects of the product, including reports of adverse effects.

"I think that has clouded the public debate on these synthetic cannabinoids, because in my opinion it is quite probable that at least part of the adverse effects have been due to this adulterated Pineapple Express product, which seems to be one of the more common products in the market."

The Ministry of Health is currently reviewing drug legislation and hope to soon bring in changes requiring manufactures to prove the safety of uncontrolled psychoactive substances before sale.

Expert commentary collected by the Science Media Centre is available here.

Earthquakes, insurance and risk

A Science Media Centre briefing earlier this week explored the ramifications for rebuilding, retrofitting and insuring buildings and structures in earthquake-prone regions following the quakes in Christchurch.

Panelists explained the types of damage that had occurred, the implications of tightening building codes, and considered whether New Zealand will eventually find itself in a similar situation to California, where the majority of property owners do not have earthquake insurance because it is unavailable or prohibitively expensive.

The briefing coincided with the launch of an information paper, jointly produced by several scientific and engineering professional societies including the Royal Society of New Zealand (RSNZ), the Institution of Professional Engineers New Zealand (IPENZ). It can be accessed here.

Audio from the briefing is on our website.
Ice, sea and brain conferences next week

It's a busy week for scientific gatherings coming up. Monday, the University of Waikato will host the annual Antarctic Conference, bringing together researchers in diverse fields who work on the polar continent, as well as artists and media who have travelled there.
Stewart Island will be the remote location for this year's NZ Marine Sciences Society conference which begins Tuesday. The theme is "Understanding, Managing, and Conserving our Marine Environment"
'The social brain' will be the topic of discussion at the INS/ASSBI Pacific Rim Conference in Auckland from Wednesday. Keynote speakers will address neuroimaging, memory, language and normal human psychology as well as brain disorders.

Quoted: Otago Daily Times

"I am exasperated ... shocked that they willy-nilly put in other chemicals to increase psychotropic effects on the user ... And they have no idea of the dose."

Research highlights

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

Aircraft influence weather: As airplanes fly through the clouds, they often punch holes through the ones that contain supercooled water, or water that has remained in liquid form below its freezing point. Now, researchers say that this phenomenon can lead to increased snowfall around the world's airports - including in Antarctica. New research shows that numerous private and commercial flights have been drilling holes and canals through clouds all along, influencing the snow and rainfall below them without even knowing it. Images available.
Science

Antarctica's last stand: In the warmest period in Earth's past 55 million years, Antarctica was ice-free and forested. The continent's vast ice sheet, began forming about 38 million years ago. Analysis of pollen and sediment from deep drill core samples has revealed that the last remnant of Antarctic vegetation existed in a tundra landscape about 12 million years ago on the continent's northern peninsula, the last part of the Antarctica to succumb to the ice.
Proceedings of the National Academy of Sciences

Water energy needs examined: A new study argues that greater focus on the energy requirements of the water sector will be a crucial part of the policy response to the huge challenges it faces in the coming decades. The authors of the study review energy usage in the water industry and link their findings to global warming considerations. Transpar¬ency in the industry's energy use is likely to be important for it to meet carbon-reduction commitments while responding to other factors such as stricter quality standards and increasing demand.
Nature Climate Change

Sugar battery shows sweet success: A glucose biofuel cell which offers the best performance yet has been reported in a new study. The cell, created by wiring glucose oxidase and laccase enzymes in a carbon nanotube disc, may provide a way of efficiently producing energy from clean sources. Not only is the energy source for such cells easily provided, the energy -producing reactions can occur at near-room temperature and neutral pH.
Nature

New alloy handles the heat: Researchers have developed a superelastic alloy that can revert back to its original shape after being deformed under a wide range of temperatures. Whereas most superelastic alloys have a strong temperature dependence to this restorative effect, this new alloy can recover from deformation at temperatures anywhere from -196 to 240 degrees Celsius with little variability over this wide temperature range.
Science

Wallaby bacteria go easy on the methane: Despite eating the same sort of grassy diet that cows do, Australia's grazing marsupials don't produce nearly as much methane gas. Scientists have now identified a gut microbe that helps explain this difference in the Tammar wallaby. By devising a culture that mimicked the conditions of this wallaby gut, the researchers eventually grew a bacterium with a genome nearly matching the dominant organisms originally seen in the foregut. The researchers propose that the bacteria may hold clues for efforts to modify fermentation in livestock so as to produce less methane.
Science

Crows hold a grudge: Crows don't just remember a transgression, they'll also tell their friends. Research into crow social learning has found that not only will crows 'scold' (cry out at) a person they saw trapping a bird, they will influence the behaviour of other crows who never wittnessed the trapping.The researchers, who used a mask when trapping birds, found that some crows scolded them when wearing the mask, despite never seeing them trap any birds.
Proceedings of the Royal Society B

Neural light switch maps mouse behaviour: Researchers have used a new method called 'optogenetics' to control reward-related neural activity in mice. By genetically altering mice to have light-sensitive neurons, scientists were able to manipulate the activity of specific areas of the brain using light via fiber-optic cables. This methodology allowed them to identify a new pathway involved in reward seeking behavior and shed light on the neurobiology of addiction.
Nature

Genes influence face gazing:
New research has found variations in the cannabinoid receptor (CNR1) gene alter the amount of time people spend looking at happy faces. Researchers analyzed the DNA from 28 adult volunteers and tested (using a "gaze tracker") how long the volunteers looked at faces in video clips showing different emotions. The team found variations in CNR1 correlated with a longer gaze at happy faces but not with faces showing disgust. The findings may provide insight into emotion processing and conditions such as autism.
Molecular Autism

X-rays reveal prehistoric plumage: A new study has used X-ray synchrotron techniques, which penetrate an object with an intense X-ray beam to probe its molecular makeup, to map out the distribution of copper and other metals in a variety of fossils. The researchers compared tissues from a range of fossil and modern animals and found that the method could resolve, to a certain extent, the coloration of fossilized bird plumage - never seen by human eyes.
Science

Blueprint for ovarian cancer revealed: A large-scale genomic analysis of the most common form of ovarian cancer has revealed the number and type of mutations in cancer cells is surprisingly simple and distinct from other ovarian cancer subtypes. The landmark study identifies aberrant genes and networks that have the potential to be targeted with therapies selected to be effective against these specific aberrations.
Nature

Obesity greatest threat for non-smoker women: While established research has shown clearly that smoking is linked to premature death and health inequalities, it is not known which causes of death are related to the social position of women who have never smoked. The results of a new study show that women in lower occupational groups were more likely to die of diseases of the heart and circulation, but not cancer.
