A plant's roots do much of their work out of sight, pulling in water and nutrients and holding the plant in place. That makes it hard to see how plants respond when conditions underground change, and how a warming climate ...
Sustainable packaging is only the beginning. What a medicine is made from—and how its ingredients are produced—matters just as much. Yet the synthesis of compounds for pharmaceutical research can still depend on fossil feedstocks, ...
From the hairs on our arms to the microscopic sensory structures of the inner ear, many tissues in the body are built with a clear sense of direction. To build these structures throughout development, individual cells must ...
The writer Malcolm Gladwell popularized the term "tipping points" to refer to the moment when a trend or social behavior crosses a threshold and rapidly spreads everywhere. In physics, tipping points occur when systems—say, ...
Wetland reclamation has long been regarded as a strategy to meet growing food demand, given the favorable soil and water conditions of wetlands. However, the trade-off between potentially greater crop production and the ecological ...
A research team has found that molten rock can carry more oxygen than its chemical composition would seem to allow. Their study is published in National Science Review.
Arabidopsis thaliana, a small flowering mustard plant used worldwide as the primary genetic model in plant biology, was long believed incapable of forming relationships with underground fungal networks. New research published ...
Wind does more than sway trees. It also plays an important role in determining an ecosystem's water-use efficiency—defined as the amount of carbon an ecosystem absorbs per unit of water lost. Water-use efficiency is an important ...
Proteases are naturally occurring enzymes that break down proteins into peptides and even single amino acids. They are useful in medicine and industrial processes, where they clean tissue, digest waste and help in the manufacture ...
Wastewater reclamation is increasingly regarded as an alternative water source to mitigate water scarcity in China. However, expanding wastewater treatment capacity alone may not be enough to ease this scarcity, since wastewater ...
