After the Rio Earth Summit in 1992, world leaders committed to pursue a sustainable development agenda. This commitment has resulted in tens of billions of dollars invested in forest conservation to mitigate climate change. But do these financial incentives work? A new study says, yes, but only if payments continue.
A new guideline from the Canadian Task Force on Preventive Health Care recommends against routine screening for thyroid dysfunction in nonpregnant adults without symptoms or risk factors. This guideline, which is based on a rigorous systematic review of the latest evidence, is published in CMAJ (Canadian Medical Association Journal).
Findings from a new study led by researchers at Dartmouth's Geisel School of Medicine show that the way in which pharmaceutical companies are permitted to share information about their drugs can influence physician prescribing practices.
The ocean hosts an inconceivable wealth of marine life, most of which remains unknown. International plans to mine minerals from the deep seafloor threaten this biodiversity hotspot. States are currently seeking to develop a legal framework for deep seabed mining. An international team of researchers from the Institute for Advanced Sustainability Studies has published a study warning against a rush to exploit deep seafloor resources and calling for coordinated efforts to develop alternative approaches.
The study analyzes the availability of non-nutritious food in Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and the Dominican Republic in the years after the Dominican Republic-Central America Free Trade Agreement (CAFTA-DR) was signed between those countries and the US, going into effect in 2006.
Social media is a rich vein of data for researchers to discover important trends in human environmental behaviour. But analysing this staggering quantity of data is a major challenge -- until now.
New research published today in the Canadian Medical Association Journal (CMAJ) reveals that brand-name drug discount cards are leading to higher health care spending in Canada -- increased costs that are ultimately passed on to patients.
Scientists say a failure of Australian management means excessive amounts of harmful chemicals -- many now banned in countries such as the EU, USA and Canada -- are damaging the country's waterways and the Great Barrier Reef.
Unless well-funded, coordinated efforts are stepped up, ongoing over-withdrawals compounded by climate change will cause dangerous water shortages for 70 million people in Central Asia's Aral Sea Basin, says a new book by 57 experts from 14 countries and the United Nations. The Basin's 2 major rivers discharge only ~10% of what once entered the Aral Sea, shrinking it by more than 80% -- 'one of the world's most severe and emblematic environmental disasters.'
By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected.
