Details of a new process have been revealed, for alloying electrochemical production of iron, either for making iron (and oxygen!) on the moon or making electrolytic iron (and oxygen) on earth. The original process was developed for release of oxygen from moon rocks, using iridium metal electrodes. The new process uses chromium-iron electrodes.
The process has the potential to further reduce the carbon dioxide produced during steelmaking, when combined with electricity production from ‘carbon-dioxide neutral’ source.

The dangers of using spreadsheets for calculations should never be underestimated, it’s so easy to make a copy paste error, or inadvertently corrupt your calculation. But it seems from reports that this may have been one of the more costly mistakes, and somehow not picked up by the peer review process, or public dissemination sufficient to reproduce the results. Economists from Harvard studied debt and GDP growth level and found that a 90% GDP ratio was a magic number which was bad for the economy, but recently an undergraduate repeated there calculations and found they were wrong (-0.1% GDP growth predicted should have been +2.2% growth). This results has been quoted by policy leaders to justify austerity measures around the world. The economists stand by their conclusions.
Correlation is not causation?

The Boeing dreamliner has made some return to service with operations beginning in Africa after the US Federal Aviation Administration issued an “air worthiness directive” allowing 787s to fly after being fitted with the modified battery.
Boeing says it put 200,000 “engineer hours” into fixing the problem, with staff working round the clock. They have not been able to find the source of the burning which took place which grounded the all 787s, instead they have had to identify all the possible ways the heating could take place and introduce measures to

BBC report about scientist jailed for faking results. Steven Eaton from Cambridgeshire was convicted in March 2013 under the 1999 Good Laboratory Practice Regulations. The court heard that while working at the Edinburgh branch of US based pharmaceutical firm Aptuit in 2009, Mr Eaton manipulated experimental results, so that a drug would proceed to human trails.
Mr Eaton was convicted by Sheriff Michael O’Grady QC, and received the maximum possible sentence of three months, the Sheriff said his powers were inadequate for this case, and a longer sentence would be justified. Mr Eaton’s defence lawyer, claimed his client did not benefit financially from the fraud, as he was only making £35,000 per year.
Mr Eaton was reported by his employers after they became suspicious and reported him to the Medicines and Healthcare Products Regulatory Agency.

Bitcoin (Bitcoin on wikipedia) has had a lot of exposure in the media recently due it’s apparent rise in value. Also with apparent troubles in the world economy it is of interest to talk about Bitcoin as a alternative to centrally managed currencies. The recent price rises seems to have triggered some speculation which pushed the price to rise exponentially, and eventually fall.
Charts from http://bitcoincharts.com/
News media has had a lot of stories talking up the price rise and the fall.
This rapid adjustment in price against the dollar has been described as a crash.
If we take a look on a logarithmic chart of the bitcoin price against dollars, we can see similar movements have occurred before. I think this would count as a crash for a centrally managed currency because it would call into question the managing authorities ability to provide price stability.
