EHPnet: Greener Education Materials for Chemists

Research The incidence of asthma has escalated over the past 20 years. Increasingly, initial asthma episodes are observed early in life (Holt 1998; Weiss 1998). In 2004, nearly 30% of the 30 million diagnosed asthmatics in the United States were < 18 years of age. The highest asthma prevalence rate (148/1,000) exists in 5-to 17-year-olds (American Lung Association 2006). Despite the often early...

Who needs a greener revolution?

How do we feed the nine billion people who are projected to inhabit the Earth by 2050? the issue is one of serious concern (ash et al, 2010; Butler, 2010), as an increase in food production of up to 40% will be needed to cope with the growing population. in response, many scientists, politicians and economists have proposed a second ‘green revolution’. their call references the first green revo...

Routes to greener plastics

How to hide a dimension from view Compacted dimensions are essential ingredients of advanced string theories; the extra dimensions used to describe the world are hidden from view, or compacted. Pendry et al. used concepts of transformation optics, in which metamaterials are designed to produce specific optical properties, to show theoretically that compacted dimensions could be possible in plas...

Will genomics guide a greener forest biotech?

Forest biotechnology has been increasingly associated with wood production using plantation forestry, and has stressed applications that use pedigreed material and transgenic trees. Reasons for this emphasis include limitations of available technologies to conform to underlying genetic features of undomesticated forest tree populations. More recently, genomic technologies have rapidly begun to ...
