The big science stories of 2012
2012 was mercifully free of major disaster-related science stories for New Zealand with the exception of this month's fatal "microbust" in West Auckland.
But plenty of science-related stories captured headlines and kept the SMC busy. Check out our archive of rapid round-ups to see some of the commentary we gathered from scientists on fracking, freshwater quality, infectious diseases, Tongariro eruption, Ross Sea protection, alcohol and tobacco policy, the Kiwifruit blight and many more issues.
Here's our picks for the top science stories of the year - picked from a top 10 list put together by our colleagues at the AusSMC in Adelaide.
1. Physicists found signs of the Higgs boson - CERN (the European Organisation for Nuclear Research) announced in July that the long-sought-after Higgs boson is real following a series of experiments conducted in the Large Hadron Collider. The Higgs boson, first postulated by Peter Higgs in the 1960s and often referred to as the 'God particle', explains why mass exists, and is the final particle required to confirm the Standard Model of physics.
2. Curiosity landed on the red planet - NASA's $US2.5bn rover Curiosity landed on Mars in August. After a 36-week voyage, the rover has started studying potentially habitable Martian environments.
3. Our genome was unravelled - Far from being junk, the vast majority of our DNA acts in at least one biochemical event in at least one cell type, according to the Encyclopedia of DNA Elements (ENCODE) Project. Analysing the entire genome to map regions of function and modification has expanded our understanding of how our blueprint is modified, and has identified new leads for understanding the genetic basis of many common diseases. ENCODE was published in over thirty research papers in four journals, including Nature.
4. First embryonic stem cell study in humans was completed - In the first report of embryonic stem cells being used in humans for any purpose, US researchers reported that transplants for eye disease (macular degeneration) in two patients appeared safe and gave them some improvement in vision after four months. This was published in the The Lancet.
5. Rare transit of Venus returned - In June, the planet Venus passed in front of the Sun for only the eighth time since the invention of telescope, and onlookers in cloud-shrouded New Zealand were lucky enough to catch a glimpse.
Interestingly, in the top Google
searches for NZ in 2012, the Transit of Venus came third
after Kim Dotcom and Tongariro in the news event category,
and ahead of the Marmite crisis and the new Give Way rule.

Science Media SAVVY - Auckland
The SMC will be holding another two-day Science Media Savvy training programme in Auckland in March 2013, following on from the very successful workshop in Christchurch earlier this year.
New Zealand academics are not expecting the world to end today, citing the poor track record of doomsday predictions thus far, but they note that human belief systems don't always follow rational lines of thinking.
The date December 21st, 2012 (today), is at the centre of a number of vague theories which predict an impending apocalypse and have attracted growing media attention.
Save the date:The workshop is planned for the 14-15th of March 2013. More details on applications will be sent out early next year.
Actual believers in the 2012 predictions are very thin on the ground, but this hasn't stopped the media from covering the issue extensively.
In response to growing interest, the US space agency NASA has provided a number of resources offering more information about the 2012 phenomenon and debunking many of the assertions made by doomsday theorists.
Earlier this week, the Science Media Centre in New Zealand has contacted experts seeking insights into the basis of such theories and why they persist in the face of contrary evidence.
Dr Matthew Dentith, Faculty Member, Department of Philosophy, University of Auckland, said:
"All doomsday theories thus far have relied upon controversial interpretations of their supporting evidence. For example, the Mayan Long Count Calendar does not predict a catastrophe on the 21st of December but, rather, the end of a cycle. To infer that the end of a cycle entails an apocalypse is like claiming the world is going to end because the year is coming to a close.
"Even if the evidence wasn't controversial, the actual argument doesn't strongly suggest, let alone entail, that we should believe there is going to be a worldwide calamity this Friday. Given the poor track record of doomsday predictions in general and the various other rival, non-doomsday hypotheses, the 21st of December, 2012, is likely to be as interesting as the 21st of December, 2011 or, indeed, any random day of the year.
Prof Marc Wilson, Victoria University Wellington, noted that even the outright absence of cataclysmic event may not lead to some people admitting they were wrong:
"What will happen when people awaiting doomsday inevitably wake up on the 22nd and everything's still there?
"This is a fundamentally uncomfortable position to be in because we all have a drive to believe that we're rational and sensible rather than gullible and credulous! The phenomenon is technically called cognitive dissonance.
"Well, people will deal with this through rationalisation. Some will rationalise it by claiming they didn't believe it in the first place (sour grapes type behaviour) and they will really convince themselves that this was the case. Some will rationalise it by revisiting the evidence and finding the flaw that leads to them to what the REAL date will be (and it starts over again)."

further commentary from both these researchers on the Science Media Centre website.
Seasons greetings from the SMC team!
It has been a busy year for the Science Media Centre and we've enjoyed working with old friends in science and the media and welcoming newcomers to the fold. Thanks for your support in what has been another big news year.
SMC Christmas/New Year hours:
Dec 21st - closed from
Jan 9th - SMC re-opens
We'll be on hand to help with queries throughout the holiday period should breaking news require scientific input. Contact SMC manager Peter Griffin - (021 859 365 email@example.com) should you require assistance over the holiday break.
Merry Xmas and a safe and happy New Year!

"If people actually believed in the end times - and economists have done work on this - then people would have pulled all the money out of their banks, they would have stopped saving and wouldn't be investing."

vaccine: Possums are a major contributor to the
spread of TB in livestock. The latest results from an
ongoing New Zealand research programme show that oral
vaccine confers TB protection in wild possums for up to 28
months. The authors state that the "longevity of protection
demonstrated here shows that an operable wildlife vaccine
against TB is feasible," and say that the next step is field
trials at a population level.
meal of mealworms: Food enthusiasts interested in
sustainable farm practices may soon have a new meat
alternative: insects. Beetle larvae (called mealworms) farms
produce more edible protein, require less land and generate
fewer greenhouse gas emissions than traditional farms for
chicken, pork, beef or milk.
Some of the policy highlights from this week:
Food safety: New Zealand this week signed an agreement with the US recognising each other's food safety systems as providing a comparable degree of food safety assurance.
Mental health: The Ministry of Health has this week signalled the launch of 'Rising to the Challenge', a new national five-year plan for mental health and addiction setting priorities for action until 2017.
