Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian impact glass could hold traces of organic compounds.

When an earthquake and tsunami struck the Fukushima Daiichi nuclear plant complex in 2011, neither the quake nor the inundation caused the ensuing contamination. Rather, it was the aftereffects — specifically, the lack of cooling for the reactor cores, due to a shutdown of all power at the station — that caused most of the harm.

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.

A forest in South Carolina, a supercomputer in Ohio and some glow-in-the-dark yarn have helped a team of field ecologists conclude that woodland corridors connecting patches of endangered plants not only increase dispersal of seeds from one patch to another, but also create wind conditions that can spread the seeds for much longer distances.

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.
