Republican candidates offer a diverse set of economic plans


SLIDE SHOW(66)
By Karen Tumulty and Perry Bacon Jr. – At a moment when the fragility of the economy ranks at the top of American concerns, sharp differences have begun to emerge in how the leading GOP presidential contenders would solve the problem — illuminating not only a diversity in approach, but a striking contrast in the candidates’ governing philosophies.

The proposals range from those that are incremental, complex and possibly achievable, to slogans and ideological rallying cries that would have enormous difficulty becoming law. more> http://twurl.nl/rc7kof

European leaders head for financial summit with no solution in sight


SLIDE SHOW(71)
By Howard Schneider and Michael Birnbaum – “We need to act together jointly,” German Chancellor Angela Merkel said Wednesday (10/25/11). “It’s not possible to have a simple solution. We will have to deal with this situation for years. . .We have a historical obligation to fulfill.”

But underlining how many issues remain unresolved, Merkel said that she would not commit any more Germany money to supporting Europe. more> http://twurl.nl/3ug8qn

Scientists target bacteria ‘quorum sensing’ as route to antibacterial therapies


R&D Mag – During quorum sensing, bacteria produce, detect, and exchange signaling molecules known as autoinducers. This process is crucial to disease development because it ultimately controls the way that bacteria express “virulence factors“—the molecules that enable the bacteria to colonize a host, evade and compromise the host’s immune response, exit and enter cells, and obtain nutrients.

By studying how to inhibit quorum sensing, scientists may be able create antibacterial pharmaceuticals for a variety of ailments.

Recently, in part due to work performed at NSLS, researchers from Princeton University and the Howard Hughes Medical Institute learned how to block a quorum-sensing mechanism in the bacteria. more> http://twurl.nl/1pn07z?

Will California’s cap-and-trade experiment catch on?


By Brad Plumer – The California Air Resources Board is putting the finishing touches on a statewide cap-and-trade system for greenhouse-gas emissions. You can bone up on the details in the Los Angeles Times. But here’s a broader question: Will California’s adventure have any effect on climate policy in the rest of the country?

A few things need to happen for California’s carbon fever to spread.

Other states will be watching to see whether California suffers from trying to reduce its carbon-dioxide emissions 25 percent below 1990 levels by 2020. Will cement plants flee the state? Will electricity bills go through the roof? more> http://twurl.nl/lmn5au
