Peer-review 'needs improvements'

28 July 2011 Last updated at 08:19 GMT By Daniel Boettcher BBC News Test tubes The committee recommended peer-review training in particular for early-career researchers MPs have recommended improvements to the way scientific papers are checked before they are published.

The House of Commons Science and Technology Committee report said this "peer-review" process of science journals should be more transparent.

Their recommendations include making scientific data publicly available, and formal training for reviewers.

Their report also recommends the appointment of an oversight body to ensure integrity in science research.

"Peer-reviewed" has become a byword for "scientifically sound and approved", but complaints have arisen in recent years that the process can sometimes work to suppress radical new ideas, and can fail to catch fraudulent research.

The committee said ethical and scientific misconduct damages peer-review and science as a whole, referring to examples like the MMR controversy.

Dr Andrew Wakefield, who suggested a link between the MMR vaccine and autism, was struck off the medical register by the General Medical Council last year after it found him guilty of serious professional misconduct over the way he carried out his research.

'Broader impact'

MPs want to see more consistent training for those involved in the review process, particularly for researchers in the early stages of their careers. In addition, they say appropriate use of internet tools could allow broader scrutiny of new research.

"Innovative approaches - such as the use of pre-print servers, open peer-review, increased transparency and online repository-style journals - should be explored by publishers," their report said.

The chair of the committee, Andrew Miller MP told BBC News: "The vast majority of science undertaken in this country is done with a high degree of integrity and the peer-review process broadly speaking is working well but we feel that improvements can be made."

One of the report's findings was that the oversight of research integrity was unsatisfactory. The MPs recommend that there should be an external regulator to deal with suspected cases of ethical misconduct, though the committee accepts that these are rare.

Mr Miller said: "It's not a case of how many times mistakes get made and how many times things slip through the net.

"It's the potential seriousness of errors or fraudulent activity that should cause us concern, and principally we need to think not just about the individual incident but the broader impact on public confidence in science."

Driving needs

27 May 2011 Last updated at 14:03 GMT Fish recently discovered in Indonesia Much of the oceanic food web will be affected by pH changes as well as by warming Whether you prefer the term "ocean acidification" or the less compelling but more accurate "ocean de-alkalisation", there's little doubt that the addition of carbon dioxide to the seas threatens to change them fundamentally over the course of the century.

Ocean acidification 101 says that the oceans absorb some of the extra CO2 going into the atmosphere.

That slowly makes seawater less alkali - or more acid, as you prefer - with major and potentially catastrophic impacts on sea life.

The science is well documented, so I won't go over that ground again except to raise an alert to look out for an interesting study coming out in the next few days.

If global ocean acidification from global CO2 emissions is the issue, you might think that the solution would necessarily be global as well.

That's certainly the way it's mainly been talked about - and in the long run, curbing carbon emissions probably is the only way to protect the coral and other shell-forming creatures that depend on seawater maintaining a constant average pH around 8.2.

But in an article in the journal Science this week, a group of US-based scientists and lawyers is making a different argument: local initiatives can be effective too, they say.

There are a couple of main strands to their argument.

Firstly, the pH of seawater varies from place to place; and in some coastal zones, it's already been pushed toward the acid by local pollution.

Ocean pH levels (Image: BBC) The oceans are thought to have absorbed about half of the extra CO2 put into the atmosphere in the industrial ageThis has lowered its pH by 0.1pH is the measure of acidity and alkalinityThe vast majority of liquids lie between pH 0 (very acidic) and pH 14 (very alkaline); 7 is neutralSeawater is mildly alkaline with a "natural" pH of about 8.2The IPCC forecasts that ocean pH will fall by "between 0.14 and 0.35 units over the 21st Century, adding to the present decrease of 0.1 units since pre-industrial times"

Secondly, there's a large and growing mound of evidence to suggest that keeping reefs, for example, safe from disease and destructive fishing and local pollution and invasive species gives them greater resistance to climate-related threats.

A couple of years ago, in sediments around Chesapeake Bay on the eastern US coast, scientists found that the northern quahog - a type of clam whose name will resonate with fans of the Family Guy cartoon series - were in trouble.

The problem was a lack of the calcium carbonate minerals from which they fashion shells.

Putting crushed-up old shells into the sediments raised the amounts available to them, which led to an increase in the number of live clams.

One of the projected impacts of ocean acidification is a decline in the availability of carbonate, which many sea creatures extract to form aragonite and calcite.

So here in Chesapeake Bay, the authors of the Science article suggest, is evidence that localised measures could provide some defence against the global trend.

If that's a science-based approach, laws and regulations may also help.

Enforcing rules on coastal erosion, and the quality of water in rivers running into the sea, can reduce local pollution that's pushing in an acidifying direction, the article argues.

And they imply that anyone who takes an interest in the issue should scrutinise local laws to see what remedies may be available.

The US, for example, has the Clean Air Act, Clean Water Act, Coastal Zone Management Act and many others at federal and state level that might be deployable.

As discussed here a few weeks ago (and more recently by David Adam in Nature Climate Change), campaign groups have regularly attempted to use legal avenues to force action on emissions - not, it should be said, with a vast amount of success.

The latest case - an intriguing twist - has been brought by Micronesia against plans to enlarge the Prunerov coal-fired power station in the Czech Republic.

Whatever the merits of the case, it's clearly one where lawyers will have ample scope to argue about the limits of jurisdiction, the attribution of climate impacts, and indeed the scale of impacts given that projections of sea level rise are far from accurate.

Lots of the difficulties melt away when local laws are used for local change.

It might not be a strategy that solves the problem - but it could bring some relief to beleaguered bivalves.
