Impacto Social y Económico en el uso de Biocombustibles

Biofuels currently represent a potential source of renewable energy. As well as that could lead to major new markets for farmers. However, only some of the current biofuel programs are feasible, and most involve high social costs and environmental ironically. The economic, environmental and social impacts of biofuels are widely debated and needs to be carefully assessed before extending public support to programs of biofuels on a large scale.The country strategy on biofuels should be based on a thorough assessment of these opportunities and costs in the medium and long term. One factor to consider is that oil reserves will run out, experts say, in fifty years. This article presents the social and economic impact of biofuel production in industrialized countries and developing countries that are or could become, efficient producers in export markets and profitable new.

Assays that Predict Outcomes Make Slow Progress Toward Prime Time

A ssays that predict outcomes in chemotherapy or monitor the effects of treatment in real time, such as Oncotype DX and Mammaprint, could see increasing use with the current emphasis on personalized medicine and avoiding unnecessary treatments. Unlike diagnostic assays, such as prostate-specific antigen measurements , these tools are intended specifically to guide decisions about when, and when not, to use chemotherapy. “We could save a lot of money and avoid a lot of side effects if these tests were more broadly adopted,” said Lee Newcomer, M.D. , senior vice president for oncology at Minneapolis-based United Healthcare, one of the largest U.S. health insurance companies. But clinicians have been slow to endorse and adopt such assays. The reasons have partly to do with continued doubt about the validity of the evidence. Most studies to date have been retrospective analyses, and although large, prospective trials are currently under way on both sides of the Atlantic, none has yet completed accrual. Also, some experts say, practice-related reasons may be behind the slow uptake of the assays.

Cloned Neandertals Still in the Realm of Sci-Fi

Since the idea of sequencing the Neandertal genome became more than a glimmer in a paleogeneticist's eye, some have asked, "Could we, should we, would we, bring this extinct human species back to life?" But for both technical and ethical reasons, experts say, bringing back a Neandertal is a pipe dream.

New Law May Be Having Some Effect on Publication Bias

P ositive trials get reported more often than negative trials, according to many studies. And despite efforts in the past decade to combat publication bias, it remains a substantial problem, according to two articles published last fall. One found that results had been published from fewer than half of the trials registered in the federal database, clinicaltrials.gov. The second article found that approximately one-third of the trials eventually published in journals changed the trial endpoint prior to publication. Despite the disconcerting results, experts are cautiously optimistic that a federal law may be having an effect. The law requires not only registration of trials but also that researchers enter results into the database. Journal policies had previously encouraged trial registration, but the new law adds clout. “The only way trial registration was going to have an effect was if someone was going to enforce it, and this is the enforcement that is needed. I think it could well address publication bias,” said Virginia Barbour, M.D., chief editor of the open-access journal PLoS Medicine, in the Public Library of Science in London. Although experts look forward to evaluating the infl uence of the law, no one — including Barbour — expects that it can entirely cure the problem. Other efforts are needed, experts say, including increased scrutiny of trial protocols and registration information during the peer-review process.

IMPACT OF GM’S BANKRUPTCY

GENERAL MOTORS’ bankruptcy, the largest ever by a U.S. manufacturer, won’t have as big an impact on the chemical industry as the precipitous decline in U.S. auto sales already has had, experts say. GM plans to emerge as the “new GM” in 60 to 90 days. It will have new owners, the largest of which will be the U.S. government, with a 60.8% stake. The governments of Canada and Ontario will have an 11.7% share, the unions will have a 17.5% stake, and the balance is going to unsecured creditors. No chemical firms are named as major creditors in the bankruptcy filing. But the list includes parts suppliers—such as Delphi, Lear, and Johnson Controls—that buy plastics from chemical companies. The economic downturn slammed the automotive industry, which already was severely struggling with its finances, says T. Kevin Swift, chief economist at the American Chemistry Council, an industry trade group. “The extent of the downturn surprised ...
