Desert Sand could be the next bonanza for desert countries

Researchers have developed a new construction material that, unlike concrete, can be made from round grains of desert sand. Finding an alternative to conventional concrete sand would relieve environmental pressure around the world. But it would be a tragedy if the discovery of the usefulness of this readily available commodity led to an unregulated gold rush.

Non-lethal impacts of seabirds’ plastic ingestion

A new study of seabirds that had ingested plastic debris has revealed a range of non-lethal impacts on their health and physiology. While seabird deaths due to swallowing plastic debris or becoming entangled in it have received global attention, the non-lethal effects on seabirds that survive plastic ingestion are less well-known.

Energy from seawater

A new battery made from affordable and durable materials generates energy from places where salt and fresh waters mingle. The technology could make coastal wastewater treatment plants energy-independent and carbon neutral.

How airplane contrails are helping make the planet warmer

New research shows that condensation trails from aircraft exhaust are playing a significant role in global warming. Experts are concerned that efforts to change aviation engine design to reduce CO2 emissions could actually create more contrails and raise daily temperatures even more.
