Is social media any good for science?
Amid a deluge of Facebook updates, Twitter "retweets" and blog posts, science is increasingly getting an airing on social networks, but the scientific community is proceeding with caution.
The Media140 conference in Brisbane yesterday looked specifically at how science-related issues are dealt with in the world of social media, from using platforms like Facebook as a forum to discuss climate change to leveraging the power of the web to run citizen science projects.
Kicking off the conference Andrew Maynard, Director of the University of Michigan Risk Science Cente, compared social media to a Jackson Pollock painting - seemingly messy and complicated, but containing underlying clarity and truth. He said social media held huge promise for science communication efforts, but a battle for authority and domination of online discussions often drowned out sensible debate.
Elsewhere conference goers heard about "sock puppets" - cynical attempts to win over online arguments with fake personailities or organisations weighing in with seemingly legitimate commentary.
Science Media Centre manager Peter Griffin joined a panel of journalists and science communicators to discuss the Pepsigate affair - how a major respected science blogging platform was nearly devastated by its move to feature a paid-for blog by scientists from beverages giant Pepsi.
Finally, futurist Kristin Alford closed things out with a keynote address on digital dysphorias - examples of how people are losing themselves in the online world with often devastating results.
If the overall impression was that there's more to lose than gain from engaging in discussion of science-related issues online, there were examples of where the medium really works for science - the use of data visualisation, crowd-sourcing science communication projects and using social networks as a form of peer-review.

Every Royal wedding has a science angle
With thousands of scientists converging on London for tonight's wedding of Prince William to Kate Middleton, even science is going out of its way to get in on the action.
The website Embargowatch has collated some of the more interesting and bizarre attmepts by scientific institutions and publications to captialise on the Royal wedding frenzy - incuding the journal Current Biology which asked in a press release pushing some research:
"Will Kate Middleton's brain response toward others change along with her title? A new paper in Current Biology examines how our social status influences the way our brains respond to others of higher or lower rank."
Back in New Zealand, Landcare Research chose to examine the weighty mountain of carbon the wedding will generate with people travelling from all around the globe to attend the wedding in person.
As Time magazine noted:
"Experts from Landcare Research predict the occasion will generate more than 12 times as much greenhouse gases than Buckingham Palace in a whole year, totaling 6,765 tons of carbon dioxide."
Elsewhere on Twitter a different science-related discussion was underway - what should the 29 year-old Prince do to address his growing bald patch - try Rogaine, hair plugs, a number 1 buzz cut or as one tweeter put it: "just leave it be, advertising his testosterone!"
OECD to New
Zealand: Go green
The Organisation for Economic Cooperation and Development (OECD) has released a report which suggests New Zealand should focus on producing and exporting technology which will counter green house gases (GHGs).
The OECD's Economic Survey of New Zealand, in addition to recommending the introduction of a capital gains tax and raising the retirement age, has stated that "Green growth would be key advantage" and "policies to pursue inclusive economic growth with sound environmental effects are essential to secure New Zealand's natural advantages in international competition"
The report notes that New Zealand has the second highest greenhouse gas output intensity in the OECD (after Australia) - almost half of which can be attributed to the agricultural sector. While there isn't any technology currently available to mitigate methane emission from farm animals, the document suggests that New Zealand could become a pioneer in developing such agri-tech and exporting it to the world.
The report also lauded the implementation of the Emissions Trading Scheme, but stressed that pricing signals in the scheme need to be strengthened. There was a further warning that other environmental assets may also need to be monetised - for instance water. With increases in intensive dairy farming, water scarcity and quality has become an issue of increasing importance.
As noted in an accompanying press release from the OECD, "The emissions trading scheme is a major development, but market based instruments to give natural assets a value should be used more broadly, notably to allocate water efficiently."

On the science radar
Quoted: Dominion Post
"There ought to be a stick as
well as a carrot...This is very contentious, but it's
starting to say that a condition of employment, or enrolment
in a childcare centre or school, is that these are the
vaccinations you must have."

In the news:
Royal carbon footprint analysed - When the UK newspaper the Telegraph wanted an estimate of the royal wedding's carbon footprint, they turned to Kiwi experts. At the request of the newspaper, the CarboNZero team at Landcare Research has completed a slightly tongue-in-cheek analysis of the carbon emissions arising from the event.
OECD recommends NZ become green exporter - The Organisation for Economic Cooperation and Development (OECD) has released its 2011 Economic Survey of New Zealand, which suggests the country focus on environmentally beneficial technology for an overseas market.
Immunisation promoted - This week (25-29 April) is New Zealand's National Immunisation Week, promoted by the Ministry of Health. An awareness campaign, which will continue in the coming months, aims to raise New Zealand's immunisation rate for under twos to 95%.
Some of the highlights of this week's posts include:

Brain areas 'nap' while you're awake: New research reveals how the brains of sleep-deprived rats briefly 'switch off' some brain regions while still being technically awake. This phenomenon was associated with the rats making mistakes in taxing motor tasks, leading the authors to hypothesise that it is also the basis of some fatigue-related errors in tired humans.
GPS captures Chilean earthquake: High-resolution GPS data has unraveled the physics of the giant earthquake that shook Chile in 2010. Satellite data allowed the researchers to model the earthquake in greater detail and with better resolution than prior earthquakes. From the models, they were able to revise the epicenter of the earthquake and calculate the speed of the fault rupture - which reached 3.1 kilometers per second.
Street smart birds need big brains: Identifying the biological traits that determine which species are likely to succeed in urbanized habitats is important for predicting global trends in biodiversity New research links relative brain size with the ability to persist in novel urban environments in passarine birds, and has important implications for our understanding of recent trends in biodiversity.
Record number of whales, krill found in Antarctic bays: Scientists have observed a "super aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula. the research highlights the changes in feeding behaviour caused by climate change and sea ice loss.
Jellyfish look up to get around: The already convoluted visual system of the box jelly fish just got a little more complex. Research has shown how four of the organisms 24 eyes always look upwards regardless of orientation. Field experiments suggest that this allows the jellyfish to use the overhead leaves of its mangrove swamp habitat as a visual guide for navigation.
Caterpillars inspire rolling robots: Researchers have been examining the diverse behaviors of caterpillars to find solutions for the new generation of search and rescue soft robots. Their work has focused on the extraordinary ability of some caterpillars to rapidly curl themselves into a wheel and propel themselves away from predators. Called 'ballistic rolling', this action serves as the basis for the design of the GoQBot, a soft material robot prototype.

Carbon nanotube TV: Carbon nanotubes may soon be part of a display screen near you. A new study shows that transistors made out of carbon nanotubes use less power than standard silicon transistors, while keeping display colors just as bright. The findings could aid ongoing efforts to make organic light-emitting diodes more energy efficient and longer lasting.
Fungus defence uncovered: Botrytis bunch rot, a disease caused by the fungal pathogen Botrytis cinerea, can devastate grape vineyards. Yet other plants can repel the invader and protect themselves by mounting a form of chemical warfare against the fungi through the production of antimicrobial substances, called phytoalexins.Scientists have uncovered a key component in the signaling pathway that regulates the production of phytoalexins to kill the disease-causing fungus.
Volcanic ash warranted air travel shutdown: Airspace closures in Europe potentially averted tragic consequences after Iceland's Eyjafjallajökull volcano shot ash high into the atmosphere in April 2010.e. Danish researchers have analysed the samples and determined that the costly flight cancellations had likely been warranted. The volcano produced ash particles that were especially fine-grained, hard, sharp, and capable of sandblasting airplane surfaces such as windows and exposed aluminum parts.

What does ecosystem collapse look like? Researchers monitoring a range of ecological vital signs in a remote lake have detected what they say is an unmistakable warning -- a death knell -- of the impending collapse of the lake's aquatic ecosystem. Their study examined the impact of species introduction in an aquatic environment and identified the extensive changes that occur as an ecosystem restructures.
Parrot vision: Although they generally have good vision, it seems Senegal parrots cannot see whats right under their noses. A new study describes for the first time the parrot visual field and suggests that parrots compensate for a lack of vision directly below their eyes by having a very touch sensitive bill.
