Emotions an overlooked key to whistle-blowing, study says

A University of Illinois study suggests that connecting with workers' emotions and personal identity can produce powerful triggers for calling out wrongdoing in the workplace. The study found that half of employees who witnessed wrongdoing on the job failed to report it due to fear of retaliation, but those who did reported being drive...

Waste water treatment plant mud used as 'green' fuel

Researchers from Rovira i Virgili University find that using mud from waste water treatment plants as an alternative fuel reduces CO2 emissions by 140,000 tonnes between 2003 and 2006. This sustainable solution enables cement factories to power their operations without harming human health.

Ethanol plants no panacea for local economies, study finds

A new study by University of Illinois researchers warns that ethanol plants can pose significant risks to local economies. The research found that employment gains from ethanol plants are often overstated and that the industry is plagued by uncertainties such as shifts in energy policy, global economics, and changing technology.

Boost for 'green plastics' from plants

Australian researchers have achieved a major advance by accumulating 30% of an unusual fatty acid (UFA) in the model plant Arabidopsis. This breakthrough could lead to the production of biofactories capable of producing oils for replacing petrochemicals used in plastics, paints, and cosmetics.

Chemical culprit in 'popcorn worker's lung' identified
