Arsenic-tolerant microbe raises possibility of new types of life on Earth , or elsewhere

The discovery of a strange bacteria that can use arsenic as one of its nutrients widens the scope for finding new forms of life on Earth and possibly beyond .

While researchers discovered the unusual bacteria here in Earth , they say it shows that life has possibilities beyond the major elements that have been considered essential .

“ That makes it very peculiar , though it falls short of being some form of truly ` alien ' life , ” commented Paul C. W. Davies of Arizona State University , a co-author of the report appearing in Thursday 's online edition of the journal Science .

Six major elements have long been considered essential for life - carbon , hydrogen , nitrogen , oxygen , phosphorus and sulfur .

But the researchers found that the bacteria , discovered in Mono Lake , Calif. , is able to continue to grow after substituting arsenic for phosphorus .

“ It makes you wonder what else is possible , ” said Ariel D. Anbar of Arizona State University , a co-author of the report .

The find is important in the search for life beyond Earth because researchers need to be able to recognize life , to know what life looks like , Anbar said .

Some 31 % say that either they or a close relative have been victims of crime over the past year , but that is down from 38 % last year and is the lowest figure since 1995 .

A more robust economic performance is reflected in rising support for private enterprise and the market economy : some 71 % of respondents across the region say that private enterprise is indispensable for development , up from 56 % in 2007 ( see chart 6 ) .

Some 58 % agree that the market economy is the only system that will make their country developed , up from 47 % last year .

Interestingly , 62 % of respondents in Venezuela hold that view ( and 80 % there back private enterprise ) even though their left-wing president , Hugo Chávez , is expropriating many private companies .

Brazil is the country which exercises most leadership in the region , mentioned by 19 % of respondents ( up from 18 % last year ) , followed by the United States ( 9 % , unchanged from last year ) and Venezuela ( 9 % , down from 11 % last year ) .

“ This stunning breach of ethics and indifference to the code belies claims by several justices that the court abides by the same rules that apply to all other federal judges , ” said Bob Edgar , the president of Common Cause .

“ The justices were wining and dining at a black-tie fundraiser with attorneys who have pending cases before the court . ”

Their appearance and assistance in fundraising for this event undercuts any claims of impartiality , and is unacceptable .

Scalia and Thomas have shown little regard for critics who say they too readily mix the business of the court with agenda-driven groups such as the Federalist Society .

And Thomas ” wife , Ginni , is a high-profile conservative activist .

Moreover , conservatives argue that it 's Justice Elena Kagan who has an ethical issue , not Scalia and Thomas .

In his program , François Hollande confines himself to banalities , saying that co-development would allow our immigration problem to be solved . ”

This notion of immigration being a burden and a problem , may be an electoral asset , but it is economically very costly .

As the economists Ian Goldin and Geoffrey Cameron , remind us in a recent book summarising the most recent knowledge of immigration ( Exceptional People : How Migration Shaped Our World and Will Define Our Future , mai 2011 , Princeton University Press , 352 pp . ) , there is wide consensus among specialists on the positive impact of migration flows on economic growth , wages and employment in countries , which admit immigrants .

Restraining immigration leads to anaemic growth and harms employment .

Fears about the impact of immigrants are based on the notion that they are liable to replace native workers , in particular unskilled ones , exerting downward pressure on wages .

Fears about the impact of immigrants are based on the notion that they are liable to replace native workers , in particular unskilled ones , exerting downward pressure on wages .

But experience shows that in reality immigrants are much more complementary to , rather than replacements of , local labor , exercising trades in which there is a shortage of local labor .

Unskilled immigrants work in sectors , which do not attract local labor and the most highly skilled ones in dynamic sectors where training does is not linked to offers of employment .

A positive effect on wages

A positive effect on wages

In the same way as a surgeon would find it difficult to work in a country with a shortage of anaesthetists , the complementarities existing between locals and immigrants bring it about that the arrival of immigrants has a positive effect on the pay of locals .

Giovanni Peri has calculated that a rise of 1 % in the migratory flow causes an increase of between 0,6 and 0,9 % in real long-term pay .

And does so without taking into account the fact that the diversity contributed by immigrants contributes to the creation of ideas and to economic growth ( a large proportion of naturalised immigrants are among American Nobel prize winners , whilst Google , Intel , Paypal , eBay and Yahoo were all founded by immigrants ) .

Migrants are also net contributors to social systems , averaging 1 % of the total budgets of European countries .
