Martian moisture makes headlines
Salty streaks identified by an orbiting spacecraft could be the first solid evidence ofliquid water – a key ingredient for life as we know it – on the Red Planet.
Evidence of salty water flows on Mars have been identified by NASA’s Mars Reconnaissance Orbiter. The findings werepublished this week in the journal Nature Geoscience.
Streaks on the surface on the planet have now been found to show evidence of hydrated salt minerals that come from water, while the surrounding area does not. The findings strongly suggest a link between the transient streaks on Martian slopes and the flow of liquid briny water.
The discovery of liquid water, and it's potential to sustain Martian life has excited New Zealand scientists.
“The discovery of moving water on Mars would really add momentum to the search for life," AUT's Prof Steve Pointing told the SMC.
"When water moves there is the opportunity for weathering of minerals and creation of nutrients to sustain life. Any Martian life would also be able to use flowing brines to disperse and colonise new areas of Mars' surface."
Prof Kathleen Campbell, from the School of Environment, University of Auckland, said Mars could be compared to the ultra-dry Atacama Desert in Chile, "where microbes living in salt crystals can survive on tiny amounts of water absorbed directly from the atmosphere.”
New Zealand-based NASA scientist Dr Duncan Steel agreed:
"There is certainly life in very salty environments on Earth... Indeed New Zealand has various extreme environments of great interest in this regard, for example hot sulphur springs.”

Kermadec sanctuary surprise
The Kermadec Islands and surrounding ocean – one of the Pacific’s most diverse and pristine marine environments – is to be protected from all forms of fishing and mining.
The Prime Minister announced the proposed Kermadec Ocean Sanctuary this week at the United Nations in New York.
The new sanctuary will extend out to the 200 nautical mile limit of New Zealand’s Exclusive Economic Zone (EEZ) around the Kermadec Islands– covering a total area of 620,000 square kilometres. All forms of resource extraction will be prohibited.
Marine scientists in New Zealand were delighted with the somewhat unexpected announcement.
“It is marvellous news and the government should be congratulated on it," said Assoc Prof Mark Costello, from the University of Auckland's Institute of Marine Science.
Victoria University Wellington's Prof Jonathan Gardner also congratulated the government on the "big and brave decision."
"The Kermadec region is an exceptional place and is very much in need of protection before large scale exploitation really commences," he said
However, Prof John Thompson, Wold Family Professor in Environmental Balance for Human Sustainability at Cornell University, was more circumspect. He warned that the decision runs the risk of scoring an own goal down the track by limiting the options for other economic or human activities.
"I’m concerned that the decision to set aside such a vast area might have been made without consideration of our limited knowledge if the area and the options and choices that it offers for the future,” he commented to the SMC.

'Blue skies' funding scrutinised
New Zealand’s leading ‘blue skies’ research fund boosts Kiwi science, but could be tweaked for greater efficiency, says a new study.
An evaluation conducted by researchers at Motu Economic and Public Policy Research institute has found that Marsden fundingincreases the scientific output of the funded researchers.
Compared to similar groups that do not receive funding, a team that is given Marsden funding shows a 6-12 percent increase in their academic publications and a 13-30 percent increase in the papers that cite their work.
Before a decision is made to fund a project, it must go through two rounds of evaluation. The new study asserts that “the significant resources devoted to the second round evaluation could be reduced without degrading the quality” of funded research.
Te Punaha Matatini Director, Professor Shaun Hendy, described the research as a "watershed study".
"Most importantly it shows that receiving a Marsden grant does lead to higher productivity and impact, at least in terms of papers published and the citations those papers receive. This does not surprise me, but it is very exciting to see the benefits of Marsden funding quantified for the first time. The study also suggests that there are no diminishing returns – if we were to double or treble the size of the Marsden fund, we would likely not see any decrease in the quantity and impact of the research carried out."
The Prime Minister's Chief Science Advisor, Professor Sir Peter Gluckman, commented:
“It is clear from this report that the Marsden fund is adding real value to our scientific enterprise as judged by traditional academic criteria. Unfortunately the study design does not allow an assessment of the broader potential impacts of basic investigator led science on, for instance public policy, social or environmental health or commercial opportunities.
"Discovery research of the type the Marsden scheme funds is ultimately at the core of our ability to innovate, to make informed decisions and to advance as a society with the knowledge and knowledge products that flow from it."
