A new report from Public Health England estimates that long-term particulate air pollution is responsible for substantial levels of mortality in the United Kingdom. Figures range from 3.8-3.9% of the proportion of deaths that can be attributed to this cause in Northern Ireland and Scotland up to 5.6% in England. Asthma UK responded to the report with concern as the majority of asthma sufferers find that air pollution makes their symptoms worse.

Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements in process efficiency, the biofuel could supplement limited supplies of petroleum-based JP-10, and might also facilitate development of a new generation of more powerful engines.

Footbridges, also commonly known as pedestrian bridges, used to link two areas are nowadays becoming beautiful works of engineering and architecture that add visual value to a landscape. While often wondrous to look at, these small structures can come at a high price if not constructed in a key location or if designed with typical materials.

Community levels of air pollution significantly reduce physical activity levels in Americans according to a new study published in PLOS One. The association of air pollution with physical inactivity was particularly strong in normal weight individuals as opposed to obese people. The study, carried out by researchers in the Uniformed Services University and The Unites States Air Force School of Aerospace Medicine, correlated levels of airborne pollutants including particulate matter and ozone with leisure-time physical inactivity in adult Americans.

Increasing energy efficiency in buildings requires substantial coordination between design engineers and architects. Researchers at Princeton University applied a common structural form-finding technique to predict the equilibrium shapes and elastic energies of dielectric elastomer minimum energy structures (DEMES).

In a new study, researchers from Imperial College Business School carried out a comprehensive nationwide analysis of the UK fleet of wind turbines, using local wind speed data from NASA. They showed that the turbines will last their full life of about 25 years before they need to be upgraded.
